STATEMENT OF RELATED APPLICATIONS
[0001] The present application is related to commonly assigned U.S.
Pat. No. 6,009,355.
[0002] The present application is a continuation of application
Ser. No. 11/240,732 filed on Sep. 30, 2005, which is a continuation
of application Ser. No. 09/900,391 filed on Jul. 6, 2001, now U.S.

08/904,855 filed on Aug. 1, 1997, now U.S. Pat. No. 6,275,231, the
disclosures of which are incorporated by reference herein.
FIELD OF THE INVENTION
[0003] The invention relates generally to control and management
systems and, more particularly, to a system for use in an
automobile which facilitates the user's control and management of
various vehicle functions.
BACKGROUND OF THE INVENTION
[0004] The concept of an automated highway system (AHS) has been
fervently pursued. Although the interpretation of the AHS concept
varies from one person to another, people implementing the concept
are incorporating more and more technology into an automobile to
improve its operations, better its safety measures, and add
conveniences to the vehicle user.
[0005] A prevalent interpretation of the AHS concept is hands-free
driving. To that end, magnets have been buried along an
experimental automated highway, and automobiles have been equipped
with magnetometers to sense the magnets to guide the moving
vehicles, thereby obviating manual steering. In another approach,
an automobile is equipped with a video system in which cameras
monitor different segments of the road ahead and feed images to
on-board computers that control steering, acceleration and braking
of the vehicle.
[0006] Although the above hands-free driving systems are at various
stages of development and will be made available to the public in
years to come, a less comprehensive system known as an "adaptive
cruise control system" will soon be publicly available. This system
is capable of adjusting a vehicle's speed to keep it moving with
the flow of traffic. Specifically, it relies on radar or infrared
sensors to measure the distance to the vehicle just ahead. If the
vehicle ahead speeds up or slows down, an onboard computer adjusts
the throttle or brakes to maintain a safe distance.
[0007] Although the ultimate AHS is in the works, it is believed
that the building blocks therefor are in place. These building
blocks include the well-known "drive-by-wire" system, TRAXXAR
stability control system, global positioning satellite (GPS)
navigation system, etc. The drive-by-wire system refers to a
throttle system responsive to electrical control signals to adjust
the speed of a vehicle, and plays a major role in the
aforementioned adaptive cruise control system.
[0008] In the TRAXXAR system, sensors are used to measure the
steering wheel position, yaw rate and lateral acceleration of the
vehicle. These sensors work with an onboard computer to
controllably apply brakes at selected wheels to avoid potential
skids.
[0009] In a well-known manner, the GPS navigation system receives
signals from a constellation of satellites. In response to such
signals, the navigation system pinpoints the vehicle's location (in
latitude and longitude). It also detects the vehicle's speed and
direction. With geographic information stored on an onboard
computer, the navigation system is capable of verbally and visually
communicating to the user instructions for reaching the
destination.
SUMMARY OF THE INVENTION
[0010] Today's automobiles are commonly equipped with an anti-lock
brake system (ABS), a cruise control system, a climate control
system, a compact disk (CD) player, a radio receiver, an
audiovisual system, a restraint system, an air bag system, a
cellular communication system, a car alarm system, and so on and so
forth. The users are overwhelmed and confused with a large number
of knobs, switches and buttons used to control the discrete
functions of the individual systems. We have recognized that as
more and more systems are being incorporated into an automobile to
implement the AHS concept, the management of the systems will be
more unwieldy than ever.
[0011] The invention overcomes the prior art limitations by
employing a master interface to manage system functions in a
vehicle. In accordance with the invention, a plurality of items are
exhibited on a display in the master interface. Each item
represents a respective one of the systems in the vehicle. The
exhibited items are arranged on the display in substantially the
same relation to one another as the systems represented thereby in
the vehicle. At least one of the items can be selected using an
indicator device (e.g., a mouse). The system represented by the
selected item can be operated to realize the functions associated
therewith.
[0012] Accordingly, it is an object of the invention that the
master interface for controlling the system functions is simple and
well organized, as opposed to using the large number of knobs,
switches and buttons to control same as in the prior art.
[0013] It is another object of the invention that the master
interface centralizes the system functions so that the user can
focus on a single interface while driving, rather than being
distracted by the large number of knobs, switches and buttons used
in the prior art, which are dispersed throughout the vehicle.
[0014] It is yet another object of the invention that the access to
the system functions through the master interface is intuitive and
direct so that a user who is not familiar with the vehicle can
instantly learn to manage such functions.
[0015] The master interface is connected to a central processor in
accordance with a system architecture wherein the central processor
also connects traditionally unrelated vehicle systems together.
With such an architecture, the central processor can coordinate the
actions of the connected systems to realize synergistic functions
such as smart driving, automatic parking, etc.

DETAILED DESCRIPTION
[0036] The present invention is directed to a technique for
effective management and control of vehicle functions in an
automobile. Traditionally, an automobile incorporates a
multiplicity of discrete systems such as a climate control system,
an audio system, an anti-lock brake system (ABS), a cruise control
system, etc. These systems are individually controlled and managed
by their own user interfaces including knobs, switches, buttons,
and displays. As the automobile industry is fervently pursuing the
automated highway system (AHS) concept, more and more systems are
being added to the automobile. As a result, the management of all
these systems becomes more unwieldy than ever.
[0037] FIG. 1 illustrates control and management system 100 for use
in an automobile, which embodies the principles of the invention.
In accordance with the invention, system 100 places the previously
unrelated automobile subsystems under centralized control, thereby
coordinating their functions synergistically and allowing data
sharing among the subsystems effectively. In addition, system 100
provides a user-friendly master control interface for the user to
manage the subsystems in an efficient manner.
[0038] As shown in FIG. 1, central to system 100 is processor 103
of conventional design. Processor 103 is connected to non-volatile
memory 107 and subsystem interface 111. The latter is an ensemble
of standard inputs/outputs (I/O's) connecting processor 103 to the
subsystems to be described. Processor 103 performs various tasks in
system 100 according to certain routines stored in memory 107. For
example, through interface 111, processor 103 collects information
from the subsystems for analysis, and transmits data and control
signals to the subsystems, thereby controlling the vehicle
functions.
[0039] Interface 111 connects the aforementioned subsystems through
common bus 113, which include master control interface 117,
automobile control subsystem 121, brake subsystem 125, traction
control subsystem 127, suspension subsystem 129, detection
subsystem 130, steering subsystem 132, operation control subsystem
136, access control subsystem 139, accessory control subsystem 143,
turn signal subsystem 147, speedometer subsystem 149, safety
subsystem 151, clock subsystem 154, wheel subsystem 157 and
application module 161.
[0040] Referring also to FIG. 2, master control interface 117 in
accordance with the invention affords the user centralized control
and management of the vehicle functions interface 117 includes
display 205, driver control keys 211, operating keys 215, accessory
keys 219, access keys 232, and indicator devices 227 and 229. When
a particular key or device is depressed or operated, the
corresponding signal is generated by interface 117 and interrupts
processor 103 to inform the latter the depression of the key or the
operation of the device.
[0041] By way of example, display 205 is a liquid crystal display
(LCD) located on a dashboard of the automobile. Display 205
includes a LCD driver (not shown) for processor 103 to control the
display graphics. This driver is also responsive to signals
generated by indicator devices 227 and 229 to perform certain tasks
to be described. In this illustrative embodiment, both devices 227
and 229 are each a mouse device which may be wireless, and can be
used to point and click at displayed options on display 205 and to
scroll various menus or screens. However, it will be appreciated
that devices 227 and 229 may be joysticks, light pens, trackballs,
touchpad, or a combination thereof, instead.
[0042] Display 205 also incorporates well-known touch-screen
circuitry (not shown) With this circuitry, the user can interact
with processor 103 by, say, touching a displayed option on display
205. Through interface 117, processor 103 receives from the touch
screen circuitry a signal identifying the location on display 205
where it has been touched. If such a location matches the
predetermined location of one of the displayed options, processor
103 determines that the option has been selected. With such
touch-screen and displayed option selection capabilities, the user
is able to obtain information on and control selectable functions
of the automobile.
[0043] Automobile control keys 211 relate to the functions provided
by automobile control subsystem 121. Subsystem 121 monitors many
aspects of the vehicle operation including the exhaust temperature,
fuel flow, engine temperature, ignition timing, individual cylinder
operations, heat exchange, etc.
[0044] When ENGINE CONTROLS key 211a is depressed, processor 103 is
prompted to collect information from, among others, engine control
system 319 (in FIG. 3) within subsystem 121. Processor 103
thereafter causes the screen of FIG. 4 to be displayed on display
205. FIG. 4 illustratively includes "ENGINE RESOURCES", "ENGINE
CAPABILITIES", "ENGINE SYSTEMS", and "ENGINE LOADS" categories
relating to the engine controls of the vehicle. Under each
category, the user may use indicator device 227 or 229 to point and
click at various engine related options to select same.
Alternatively, utilizing the touch-screen capability, the user may
touch the options on the screen with his/her finger to achieve the
selection. The selected options are highlighted in a first color,
and the readings and/or statuses corresponding thereto are shown in
the respective blanks following the items.
[0045] For example, when OIL LEVEL option 371 is selected, the
amount of oil in the engine is indicated, i.e., whether the current
level of engine oil is high, medium or low. By selecting
PERFORMANCE MODES option 373, the user learns whether the engine is
in an aggressive mode or a fuel economy mode. The aggressive mode
offers a high power output and should be used when sudden
accelerations and decelerations (e.g., passing other vehicles) are
anticipated. Otherwise, the fuel economy mode is recommended. When
one of the two modes is indicated on line 375, the line is
highlighted in a second color, indicating that another performance
mode option is available for selection. In this instance, when the
user points and clicks at line 375, the other performance mode
option is displayed. The user may then point and click at such
other option to change the performance mode.
[0046] In accordance with an aspect of the invention, subscreen 377
is used to graphically depict the engine compartment of the
vehicle. By way of example, displayed items 381 through 389 in
subscreen 377 depict the radiator, battery, fuse box, air cleaner,
brake fluid reservoir, transmission fluid reservoir, windshield
washer reservoir, oil compartment and engine block in the engine
compartment, respectively. It should be pointed out that the
relative positions of these displayed items correspond to those of
the depicted components in the actual engine compartment. Knowing
the relative positions of the components under the hood of the
vehicle, the user can easily identify and point and click at
selected items to quickly access information concerning the
corresponding components. For example, when displayed item 381
depicting the radiator is selected, options 391 and 392 relating to
the radiator are highlighted, and the readings of the current
coolant temperature and coolant level are shown in the respective
blanks. When displayed item 388 depicting the oil compartment is
selected, options 393, 371 and 394 relating to the oil compartment
are highlighted, and the readings of the current oil pressure, oil
level and oil temperature are shown in the respective blanks.
[0047] As shown in FIG. 3, subsystem 121 also includes electronic
transmission/throttle system 325, which operates under the control
of processor 103 in accordance with certain drivetrain routines.
The program instructions defining these routines are stored in
memory 107 in this instance. Alternatively, they may be stored in a
memory (not shown) in subsystem 121.
[0048] Instructed by one of the drivetrain routines, which is
denoted 400 in FIG. 5, processor 103 detects whether the user has
selected a transmission gear different from the currently engaged
gear, as indicated at step 403. The gear selection is achieved by
depressing DRIVETRAIN key 211b, followed by operating indicator
device 227 or 229. For example, after depressing key 211b and
moving device 227 forward (backward) causes processor 103 to
initiate a signal to system 325 to select a forward (reverse)
gear.
[0049] If the user has selected a different gear at step 403,
routine 400 proceeds to step 405 where processor 103 determines
whether the selected gear is opposite the automobile's moving
direction. If the selected gear is a reverse (forward) gear, and
the automobile is moving forward (backward), processor 103
overrules the user's selection, as indicated at step 407. Routine
400 then returns to step 403. Otherwise if the selected gear and
the moving automobile direction are both forward or reverse,
routine 400 proceeds to step 408 where processor 103 causes brake
subsystem 125 to apply the brakes of the vehicle, and thereafter to
step 409 where it causes system 325 to engage the selected gear.
Routine 400 proceeds from step 409 to step 417 to be described.
[0050] If at step 403 processor 103 does not detect any gear change
by the user, it causes system 325 to enter an automatic
transmission mode in which system 325 automatically shifts the
gears in a well-known manner, as indicated at step 413. Routine 400
then proceeds to step 417 where processor 103 coordinates the
operation of system 325 with that of traction control subsystem
127, which may be of the type of the TRAXXAR stability control
system, to prevent skids. At step 421, processor 103 coordinates
the operation of system 325 with that of suspension subsystem 129
including shock absorbers to afford a smooth, comfortable and safe
ride. From step 421, routine 400 returns to step 403 described
above.
[0051] Another drivetrain routine causes system 325 to perform gear
shifting in cooperation with other subsystems such as detection
subsystem 130 and brake subsystem 125 to handle certain road
conditions, Detection subsystem 130 includes radar, sonar, infrared
sensors, Doppler radar, magnetometers and/or other object finder
mechanisms, and is used for, among other things, monitoring the
road condition ahead. For example, when an upcoming curve is
detected, system 325 handles the transmission accordingly while the
brakes are controllably applied by brake subsystem 125 to avoid any
skid.
[0052] It should be noted at this point that suspension subsystem
129 also includes a height actuator, whereby processor 103 can
controllably adjust the height of the vehicle. Thus, continuing the
above example, when detection system 130 detects the upcoming
curve, processor 103 may also cause the vehicle height to be
lowered to increase its stability. In another instance, when
detection system 103 detects a raised road surface ahead, processor
103 causes the height of the vehicle to be increased to clear the
elevation, thus avoiding scraping the bottom of the vehicle.
[0053] Navigation system 329 in FIG. 3 provides onboard and/or
on-line navigation capability. In a well-known manner, system 329
receives signals from a constellation of satellites which is part
of the global positioning system (GPS). In response to these
signals, system. 329 pinpoints the automobile's location in
latitude and longitude. In addition, system 329 receives the
vehicle directional and speed information from a compass subsystem
(not shown) and an accelerometer (not shown), respectively.
[0054] Specifically, the user depresses NAVIGATE key 211c to
request instructions for a given destination from navigation system
329. When the depression of key 211c is detected by processor 103,
the user is elicited for information concerning the destination,
any intermediate stops, etc. Such elicitation is realized by posing
questions on display 205 and/or by uttering those questions using a
synthesized voice through an audio output. The user then provides
verbal responses thereto through an audio'input. Relying on
standard speech recognition circuitry in system 100, navigation
system 329 recognizes and registers the responses. Using stored map
information, system 329 then provides on display 205 a suggested
route leading to the destination. Furthermore, based on the
knowledge of the vehicle's instantaneous speeds and directions,
system 329 is capable of verbally and visually directing the user
to the destination.
[0055] Because of the limited capacity of the storage for the map
information or because the map information needs to be updated from
time to time, it will be appreciated that system 329`would instead`
obtain the necessary, latest map information from an on-line
service through a cellular or wireless connection.
[0056] In addition to directing the user to a given destination;
system 329 through processor 103 cooperates with weather system 332
and traffic system 336 to be described. In accordance with an
aspect of the invention, systems 332 and 336 jointly provide on
display 205 updates regarding traffic congestions, weather
conditions, hazards, highway warnings along the route suggested by
system 329.
[0057] FIG. 6 illustrates one such navigation screen on display
205. On this screen, indicator 450 marks the current position of
the vehicle. The suggested route (shown in boldface) by navigation
system 329 is numerically denoted 453. Traffic indicator 455 is
provided by system 336 to indicate where traffic congestion is on
route 453. Similarly, weather indicators 457, 459 and 461 are
provided by system 332 to indicate the cloudy, rainy and foggy
conditions, respectively, at different points along route 453. It
will be appreciated that these traffic and weather indicators may
be colored and/or flashing to attract the user's attention.
[0058] Weather system 332 derives weather conditions from computer
files obtained from an on-line service through a cellular or
wireless connection. In an alternative embodiment, system 332 may
include such well-known avionics as weather radar and lightning
strike finders to detect weather conditions. By depressing WEATHER
key 211d, the user is provided on display 205 with a map centered
at a reference point indicative of the vehicle location. As to be
described, system 100 runs a windows based operating system. With
such an operating system, the user may operate indicator device 227
or 229 to point and click at a selected point on the map, and drag
same to create a window surrounding a desired location, which may
or may not include the vehicle location. Processor 103 causes
system 332 to retrieve the relevant computer weather files, and
derives therefrom the weather information regarding the area
defined by the window.
[0059] FIG. 7 illustrates one such window which is created on
display 205 and which surrounds the Los Angeles area. In this
instance, the vehicle location is numerically denoted 481. As shown
in FIG. 7, temperatures (denoted 483 and 485' for example) are
indicated in parts of the subject area corresponding thereto. In
addition, among others, weather indicators 487, 489, 491, 493 and
495 respectively indicate the rainy, cloudy, sunny and foggy
conditions and storm warnings in the corresponding parts of the
area. Moreover, weather center 496 and surface observation center
497 are indicated. The user may point and click at the respective
centers to obtain the corresponding reports on weather and surface
observation of the local area. These reports are generated on
display 205 in text and/or read to the user through the audio
output of system 100.
[0060] By default, system 332 provides the current weather
information on display 205. Otherwise if the user specifies a time,
system 332 provides the user with a weather forecast if the
specified time is in the future, and weather history if it is in
the past. With such future, current and/or past, short and/or long
range weather information, the user can effectively plan his/her
trip, and avoid unfavorable weather conditions.
[0061] Using the weather information from system 332, processor 103
issues on display 205 travel advisories such as requesting the user
to check tire pressures after a drastic temperature change. In
addition, processor 103 may cause a release of heat to warm the car
battery to boost its starting power in cold weather, cause
additional venting of engine heat in hot weather, and ensure
closing of windows and doors in inclement weather.
[0062] It will be appreciated that weather system 332 may also be
capable of obtaining weather information from such systems as the
United States satellite systems, Delta radar, local area radar,
etc. In addition, system 332 may be capable of gathering further
information including United States current surface maps, wind
chill maps, jet stream maps, winter travel hazards, forecast
highs/lows, tropical weather, surface wind maps, grain and farm
weather maps, etc.
[0063] Traffic system 336 will now be described. Similar to weather
system 332, system 336 is capable of obtaining computerized traffic
information from an on-line service through a cellular or wireless
connection. In an alternative embodiment, system 336 may include
such well-known electronics as a line-of-sight radar, forward
infrared radar, and/or Doppler radar, each with terrain following
capabilities, to sense surrounding traffic conditions.
[0064] By depressing TRAFFIC key 211e, the user is similarly
provided on display 205 with a map centered at a reference point
indicative of the vehicle location. The user may then operate
indicator device 227 or 229 to point and click at a selected point
on the map, and drag same to create a window surrounding a desired
location, which may or may not include the vehicle location. In
responses processor 103 causes traffic system 336 to obtain the
relevant traffic information regarding the area defined by the
window. In accordance with another aspect of the invention, the
traffic information may be overlaid on an existing window (e.g., a
window previously created for obtaining weather information) by
pressing TRAFFIC key 211e.
[0065] Referring again to FIG. 7, the illustrative weather window
includes overlaid traffic information in this instance. For
example, traffic indicator 498 indicates traffic congestion near
"Anaheim" inside the window. In addition, by pointing and clicking
at traffic center 499, the user may obtain a traffic report in text
and/or voice concerning the local traffic. After learning the
traffic situations in the area of interest, the user can
effectively plan his/her route to avoid potential traffic
congestion or hazards.
[0066] In addition, traffic system 211e is capable of storing and
recalling traffic maps and sending same to third parties using a
cellular or wireless connection.
[0067] The aforementioned detection subsystem 130 also helps
provide an adaptive cruise control capability. Specifically,
subsystem 130 measures the distance to the vehicle just ahead. With
electronic transmission/throttle system 325 and brake subsystem
125, processor 103 adjusts the vehicle's speed to keep it moving
with the traffic flow. If the vehicle ahead speeds up or slows
down, subsystem 130 signals processor 103 to accordingly adjust the
throttle or brakes to maintain a safe distance.
[0068] When SMART DRIVING key 211f is depressed, processor 103
causes a menu to be displayed on display 205. This menu includes
selectable items such as automatic driving and automatic parking.
If automatic driving is selected, upon detecting by detection
subsystem 130 an automated highway processor 103 graphically
depicts on display 205 the highway segment. Illustratively,
processor 103 causes the screen of FIG. 8 to be displayed.
[0069] In FIG. 8, indicators 503, 507, 509 and 511 demarcate the
highway lane incorporating AHS technology which the subject vehicle
(denoted 513) is in. In this instance, these indicators mark the
locations of magnets buried in the AHS highway lane, which are
detected by the magnetometer in subsystem 130. Steering subsystem
132 relies on the detection of the magnets which are separated in
predetermined intervals on both sides of the lane to properly steer
subject vehicle 513, thereby realizing automatic driving. In
accordance with an aspect of the invention, processor 103 keeps
track of the occurrences of the magnets in the AHS highway lane. If
for any reason the magnets are missing or undetected for a
predetermined number of intervals in a row, which may adversely
affect the proper steering of the vehicle, processor 103 causes a
warning to come on the display. If the user in response to such a
warning redirects arrow 516 which is aligned with the AHS lane to
point toward, say, the left lane, which is a non-AHS lane,
processor. 103 is interrupted to terminate the automatic driving. A
textual message 517 immediately comes on to confirm the termination
of the automatic driving. With such a confirmation, processor 103,
among other things, causes turn signal subsystem 147 to be
described to activate the left turn signal. The user may then
manually steer the vehicle into the left lane.
[0070] In accordance with another aspect of the invention, the user
may define comfort zone 528 surrounding subject vehicle 513, in
which any of left vehicle/object 521, right vehicle/object 523,
front vehicle/object 525, and rear vehicle/object 527 is not
allowed. Comfort zone 528 may be realized by using indicator device
227 or 229 to point at indicators 529a, 529b, 529c and 529d
individually, and dragging same away from subject vehicle 513.
Alternatively, the user may select CLEARANCE options appearing in
the respective boxes representing the vehicles/objects to define
the comfort zone. The selection of one such option is followed by a
prompt for the desired minimum distance from the corresponding
vehicle/object, if any.
[0071] Processor 103 is programmed to control the steering,
throttle and brakes of the vehicle in an attempt to keep any
surrounding vehicles/objects outside comfort zone 528. If any such
vehicle/object unavoidably comes within zone 528, processor 103
would issue on display 205 a warning of the zone violation,
provided that COMFORT ZONE warning option 531 has been selected. A
reference zone is defined by the vehicle manufacturer to be the
minimal space surrounding the subject vehicle to avoid collisions
with a good confidence, taking into account the instantaneous speed
of the subject vehicle relative to the surrounding
vehicles/objects. By design, comfort zone 520 cannot be made
smaller than the reference zone. Selection of REFERENCE ZONE option
533 enables the user to set comfort zone 520 to be the same as the
reference zone. In any event, no matter how large comfort zone 520
is, any vehicle/object coming within the reference zone
automatically causes issuance of a collision alarm. In response to
such an alarm, the user takes emergency measures to avoid any
collision.
[0072] Subsystem 130 in this instance detects not only the
vehicle/object ahead as in the adaptive cruise control case, but
also any other surrounding vehicles/objects. Subsystem 130
periodically communicates to processor 103 data concerning the
speeds and the coordinates of any surrounding vehicles/objects,
relative to the subject vehicle, to realize the above comfort zone
and reference zone protections. If the user selects SHOW TRAFFIC
option 535, processor 103 causes display 205 to show the current
positions of any actual surrounding vehicles/objects, relative to
the subject vehicle. With such visual information, the user is
fully aware of his/her driving environment, thus improving the
user's safety especially in night driving.
[0073] As mentioned before, the user can also select automatic
parking of the vehicle from the above menu invoked by depression of
SMART DRIVING key 211f. If the automatic parking option is
selected, after the vehicle comes to a complete stop, automatic
parking routine 500 stored in memory 107 is invoked. When
instructed by this routine, which is depicted in FIG. 9, processor
103 causes display 205 to show thereon the positions of the
surrounding objects relative to the subject vehicle, as indicated
at step 543.
[0074] At this point, the user may touch the screen of display 205
to define a parking space into which the vehicle is to be parked.
In order to carry out parallel parking effectively, this parking
space needs to be reasonably suitable for the vehicle to be
maneuvered into. Processor 103 at step 547 computes the coordinates
defining the selected parking space. Knowing the respective
coordinates of the subject vehicle, the surrounding objects and the
parking space, processor 103 at step 551 determines the instants at
which and extents to which the vehicle, is to be accelerated and
decelerated in the course of the parking, and at step 553 the
instants at which and extents to which the steering wheel is to be
turned and returned. At step 555, processor 103 causes a computer
simulation to be performed using the speed and steering parameters
just determined to verify that the automatic parking is, feasible,
without running into any surrounding objects. At that point, the
user may depress ANIMATION key 219j to view on display 205 the
simulation in which the subject vehicle moves into the user defined
parking space in an animated fashion. At step 559 processor 103
determines whether the vehicle can be properly parked under the
above conditions. If processor 103 determines that the automatic
parking is unrealizable, processor 103 informs the user of same, as
indicated at step 563. In response, the user needs to select
another parking space or may attempt to park the vehicle
manually.
[0075] Otherwise if processor 103 determines that the automatic
parking is realizable, processor 103 sends an audio and video
message to request the user to get off the vehicle before the
automatic parking is engaged, as indicated at step 567. In the
preferred embodiment, the user is provided with a transmitter
(e.g., transmitter 700 to be described) for remotely signaling to
processor 103 to carry out the actual parking after the user leaves
the vehicle. When it is so signaled, processor 103 at step 571
coordinates the actions of electronic transmission/throttle system
325, brake subsystem 125 and steering subsystem 132 to realize the
automatic parking according to the devised scheme. During the
automatic parking, for any reason, the user may also use the
aforementioned transmitter to signal processor 103 to abort the
parking. In addition, processor 103 may cause a predetermined
audible signal to be emitted to alert surrounding people while the
vehicle is being parked.
[0076] In addition, the automatic parking may also be achievable by
training the vehicle. For example, let's say the user often parks
his/her vehicle in a particular garage. In that case, processor 103
may be set in a training mode in which as the user maneuvers and
moves the vehicle from a predetermined location outside the garage
to a designated parking space in the garage, processor 103
registers the coordinated operations by the user of the systems
involved. Thus, with the training, each time when the vehicle is
placed at the predetermined location and put in an automatic
parking mode, processor 103 repeats the system operations, as
registered, and accordingly parks the vehicle in the designated
parking space.
[0077] Conversely, processor 103 can be programmed to perform the
inverse function to the above automatic parking, i.e., to direct
the vehicle out of a parking space.
[0078] When emergency key 211g is depressed, processor 103 causes
emergency options to be displayed on display 205. These options may
include police-type emergencies, medical emergencies, mechanical
problems, panic measures, etc. For example, upon selection of the
police-type emergencies option, the user may be queried whether
he/she is a victim. If the user responds affirmatively, processor
103, immediately establishes a phone or modem connection with a
police authority to automatically furnish such preliminary
information as the identity of the user, description of the vehicle
and emergency contacts, which are pre-recorded, along with the
current location of the vehicle identified by navigation system
329. If possible, the user may also add, in the communication, the
nature of the emergency and current statuses of the user and any
passengers. By automatically communicating at least the preliminary
information to the proper authority in case of an emergency, the
user can be instantly reached and helped.
[0079] System 100 also includes a panic alarm, audiovisual
recording facilities to audio- and video-tape potential crime
scenes for later review when the user selects the panic measures
option. In addition, system 100 may include broadcasting
capabilities to disseminate alarm signals (e.g., a car fire alarm)
via citizen's band (CB) for example.
[0080] Security system 343 in FIG. 3 works closely with access
control subsystem 139 to afford controlled access to the vehicle's
doors, windows, trunk, hood, accessories, system software, etc. In
this illustrative embodiment, the holder of a master key to
security system 343, who is mostly likely the vehicle owner, is
able to assign security levels and/or access codes to other
authorized users to implement the controlled access. This master
key may be in the form of a special code initially provided by the
vehicle manufacturer.
[0081] For example, using system 343, the master key holder assigns
to each authorized user a respective personal identification number
(PIN), along with a clearance level. When a person attempts to,
say, adjust an accessory, which is pre-assigned with a selected
security level, processor 103 elicits from the user his/her PIN
through display 205 or a similar interface. In response, the person
may enter a PIN by touching the appropriate keys on a displayed
keypad. Upon receiving the PIN entry, processor 103 checks with
system 343 whether the PIN is valid. Verification of the PIN
ensures that the person is an authorized user. If the PIN is valid,
processor 103 then compares the clearance level associated with the
PIN with the security level of the accessory in question. Only when
the clearance level is higher than the security level, would the
authorized user be allowed to adjust the accessory.
[0082] The above security measures may also be used to arm and
unarm anti-theft capabilities in the vehicle, which may be based on
infrared, sonar or other similar surveillance technology. In
addition, selected individual items in the vehicle are digitally
encoded so that they would not be functional if someone removes and
attempts to re-install them without proper codes.
[0083] Moreover, in this illustrative embodiment, security system
343 includes a receiver for receiving an RF signal containing
security and personal preference data. Before gaining access to the
subject vehicle, a user needs to furnish at least the security data
for verification. If the security data is valid, processor 103
causes system 343 to unlock the doors and unarm the anti-theft
capabilities of the vehicle. To that end, each authorized user is
provided with an access card (analogous to a driver's permit) in
the form of a standard integrated circuit (IC) card (also known as
a "Smart Card"). FIG. 10 illustrates one such IC card, denoted 600.
Security data including a user PIN and control information is
stored in memory 603 in card 600. This security data may be
encrypted in accordance with a well-known encryption algorithm such
as an RSA or a digital encryption standard (DES) algorithm.
[0084] The aforementioned control information includes an access
code indicative of the extent to which a user is allowed to control
the vehicle functions and/or access its hardware and software.
Depending on the access code, the user may be accorded full
operating privilege, or one of the more restricted operating
privileges respectively designed for family members, mechanics,
police officers, etc.
[0085] In addition to the aforementioned security data, personal
preference data may also be stored in memory 603. The personal
preference data contains information regarding the user preferred
settings of the doors, locks, windows, engine, performance
profiles, climate control, audio system and other vehicle
functions.
[0086] FIG. 11 illustrates transmitter 700 into which card 600 can
be inserted. Specifically, transmitter 700 includes transmitter
interface 703 for receiving card interface 607. Interfaces 703 and
607 are electrically compatible with each other, and may be in
accordance with the PCMCIA interface standard. Before entering the
subject vehicle, the user needs to couple interface 607 to
interface 703. To gain entry to the vehicle, the user needs to
depress a START button in operating portion 707 of the transmitter
to initiate an RF signal directed to the receiver of system 343. It
should be noted at this point that a PARK button is also provided
in portion 707 for initiating automatic parking described
before.
[0087] Upon detecting a depression of the START button, data
processor 709 communicates with card processor 611 to have a copy
of the above-described security data and personal preference data
in memory 603 transferred to transmitter 700. Data processor 709
formats the received data pursuant to a predetermined protocol, and
causes signal generator 711 to transmit the RF signal, whose
waveform is modulated by the formatted data.
[0088] After the receiver of system 343 receives the transmitted
signal, it recovers therefrom the security data and personal
preference data. Processor 103 then performs a security check based
on the received security data. If it determines that the user is
not an authorized user, he/she would be denied access to the
vehicle. Otherwise, processor 103 causes the driver door of the
vehicle to be unlocked, and accords the proper operating privilege.
In addition, processor 13 stores the received personal preference
data in memory 107. Based on such received data, processor 103
effects the preferred vehicle settings to personalize the vehicle
functions.
[0089] It will be appreciated that, instead of an IC memory, the
aforementioned security and personal preference data may be stored
in a magnetic medium such as a standard magnetic stripe, or in the
form of a one-dimensional or two dimensional bar-code on a card. In
the case where the bar-code is used, security system 343 may
incorporate a conventional bar-code scanner for reading the encoded
data. In addition, the stored data need not be transmitted via an
RF medium. It may well be transmitted via a laser, infrared or any
other medium, or through a telephone network, a private network, a
cellular network, the Internet or any other network, as long as the
vehicle is equipped with the appropriate data receiver.
[0090] Depression of LIGHTS key 211i in FIG. 2 invokes on display
205 displayed options including, for example, all lights on/off,
running lights on/off and flashers on/off. For each option, the
user may further select the light operation durations, and set
weather, hazardous, ambient light conditions under which the light
would be automatically turned on.
[0091] Depression of WARNINGS key 211j prompts processor 103 to
display on display 205 predetermined advisories and cautions on
operating the vehicle, such as the advisory "adjusting seat while
driving could result in loss of vehicle control."
[0092] Upon a start-up of system 100, periodically or when
DIAGNOSTICS key 211k is depressed, processor 103 polls each system
therein for a self-test result. The system, when polled, performs
an active self-test and reports the test results to diagnostic
system 349. The latter analyzes the results, and communicates any
exceptions to processor 103. Processor 103 causes display 205 to
display a clear status for those systems having no identifiable
problem, and to graphically indicate the locations of identified
irregularities for the other systems, along with messages
describing the irregularities. Some irregularities may cause
processor 103 to restrict certain vehicle operations until a
corrective action therefor is taken.
[0093] The exception data received by processor 103 is stored in
memory 107. Alternatively, they may be stored in a secure storage
such as a "black box" which would survive an accident involving the
subject vehicle. In the event of an accident, the exception data
would be retrievable for determination of any mechanical cause for
the accident.
[0094] Key 2111 is currently unused. However, in accordance with an
aspect of the invention, key 2111 can be programmed to replace any
function key in system 100 and its associated function. For that
matter, as a provision for the user preferences, system 100 allows
the user to re-program or re-designate each function key in system
100 to realize his/her preferred key arrangement. The
re-designation is effected by the user's stepping through a
menu-driven program, and registered by processor 103 as one of that
user's preferences.
[0095] Depression of DEMO key 211m allows the user to access a
self-guided demonstration provided by demonstration system 353.
When the vehicle is in a showroom before its sale, the
demonstration comprises a multimedia presentation on display 205,
providing sales-type information including information on each
feature and aspect of the vehicle, and functions afforded by master
control interface 117. After the sale of the vehicle, the
demonstration may include pre-recorded video programs for showing
on display 205 operating procedures to realize different vehicle
functions. In particular, such video programs demonstrate
step-by-step operations of interface 117 to implement such
functions as smart driving, obtaining weather and traffic
information, etc. Thus, with this demonstration capability, a user
who is not familiar with the subject vehicle can instantly learn to
manage the various vehicle functions.
[0096] In accordance with another aspect of the invention,
demonstration system 353 may be put in a rehearsal mode in which a
prospective vehicle user can be trained and tested for his/her
dexterity and familiarity with the vehicle functions. In such a
rehearsal mode, traffic situations and vehicle conditions are
simulated on display 205. At the same time, the prospective user is
required to operate master control interface 117 to properly handle
each given scenario. Only after satisfying the operating
requirements, may the prospective user be granted the
aforementioned access card (or "driver's permit") according the
appropriate operating privilege.
[0097] Depression of RESET key 211n allows the user to
reset/restart selected systems in system 100 for reasons of
malfunction or nonperformance. The reset is accomplished by reset
system 357, and can also be selected by depressing MENU key 219c or
INDEX key 219g to be described. When a system is reset, power to
the system is temporarily cut off. After regaining power, the reset
system runs a restarting routine, and either resumes normal
operation or identifies any problems to processor 103. In the
latter case, processor 103 posts necessary messages to alert the
user of the reported problems.
[0098] Operating keys 215 relate to the functions provided by
operation control subsystem 136. With SHIFT key 215a, each other
key on interface 117 corresponds to two functions depending on
whether the key is depressed together with SHIFT 215a.
[0099] Depression of ENTER key 215b allows the user to initiate an
action. If no action is required, depression of key 215b causes
generation of a warning tone.
[0100] Depression of ZOOM(+) key 215c allows the user to obtain
information not presently displayed, thereby providing other
related subjects such as owner's manual material, tips, warnings,
cautions, etc.
[0101] Depression of ZOOM AWAY(-) 215d effects the inverse function
to depression of key 215c. That is, it allows the user to leave a
related subject to continue with the original subject.
[0102] Depression of SET-UP key 215e allows the user to set
parameters in system 100, which affect the functions of master
control interface 117, selected aspects of the vehicle, priority of
menu selections, access by other users to the hardware and software
of the vehicle, etc. To facilitate setting of new parameters, after
key 215e is depressed, operation control subsystem 136 causes
display 205 to show thereon information about installed features,
accessories, options, original equipment, dealer installed
equipment, after market installations/removals, etc. In addition,
information about the vehicle's capabilities, safety features,
legal requirements, equipment installers, repair facilities,
maintenance records, software revisions and updates, etc., which is
stored in subsystem 136, may be accessed and reviewed using the
set-up function as well.
[0103] In this illustrative embodiment, a windows based operating
system of the type of the MICROSOFT WINDOWS operating system is
installed on system 100. Specifically, a copy of the operating
system software is stored in memory 107. Utilizing such an
operating system, processor 103 can be programmed to control
display 205 to provide organized data presentation through one or
more windows.
[0104] By depressing SPLIT SCREEN key 215f, followed by clicking
and dragging indicator device 227 or 229, multiple windows can be,
created on display 205. Advantageously, with multiple windows,
certain actions can be effectively coordinated and cross-checked.
For example, a vehicle function may be monitored in a first window
while it is modified via menu selection in a second window. As a
result, the modification can be immediately observed in the first
window. Thus, with multiple windows, various menus and vehicle
functions can be simultaneously accessed and monitored.
[0105] FIG. 12 illustrates multiple windows numerically denoted
801, 803 and 805, respectively, created on display 205 using the
SPLIT SCREEN capability. As shown in FIG. 12, the user may utilize
window 753 to realize the navigation function provided by
navigation system 329. At the same time, windows 755 and 757
respectively provide first and second menus for the user's
selection.
[0106] Depression of RELEASE key 215g at a particular screen
effects the "enter" function, followed by an immediate return to a
predetermined screen such as the main menu or "home" screen. Thus,
unlike key 215d, depression of key 215g does not provide an
incremental return to a previous screen, but an instant return to
the home screen.
[0107] BRIGHTNESS key 215h comprises a standard variable resistor
such that when it is pushed one way (the other way), the intensity
of display 205 is increased (decreased). Utilizing the proper
intensity, the user can readily view display 205 under different
ambient light conditions (e.g., night time, excess glare, bright
sun, etc.).
[0108] Access keys 232 relate to functions provided by access
control subsystem 139 in FIG. 1. Depression of WINDOWS key 232a
invokes the screen of FIG. 13 on display 205. As shown in FIG. 13,
triangles 810, 812, 814 and 816 correspond to the driver side front
window, driver side rear window, passenger side front window and
passenger side rear window, respectively. Indicators 821, 823, 825
and 827 on the hypotenuses of the respective triangles indicate the
extents to which the corresponding windows are open. The user may
touch the indicator on the screen to raise (or lower) it along the
hypotenuse. In response, processor 103 causes access control
subsystem 139 to close (or open) the window accordingly.
Alternatively, the user may operate indicator device 227 or 229 to
point at one of the indicators and drag same along the hypotenuse
to control the corresponding window opening.
[0109] In addition, a SMART WINDOWS function on sub-screen 840 may
be selected by touching ON option 842 on the screen or pointing and
clicking at same. With the SMART WINDOWS function selected, for
example, subsystem 139 causes the windows to be completely closed
upon a shut-off of the engine or an activation of air conditioning.
When coupled with a SMART CLIMATE function to be described, the
SMART WINDOWS function includes slightly opening selected windows
to vent out excess heat prior to the user's arrival, thereby
pre-conditioning the vehicle. In addition, when an AUTO function on
sub-screen 840 is selected, the user can specify the vehicle speed
at which the driver side front window is made completely open or
closed. By touching on the screen, or pointing and clicking at
blank 845 or blank 850, choices of speed are listed beneath the
blank. For example, by selecting a zero speed for blank 845 ahead
of a toll plaza, the window in question would be completely opened
when the vehicle stops at a toll booth, thereby conveniently
allowing the user to pay tolls.
[0110] The screen of FIG. 13 may also be invoked by depressing
DOORS key 232b. Flaps 851, 853, 855 and 857 in FIG. 13 correspond
to the driver side front door, driver side rear door, passenger
side front door and passenger side rear door, respectively. By
touching one of the flaps on the screen with a finger or pointing
and clicking at the flap with indicator 227 or 229, subsystem 139
including a door actuator controllably closes the corresponding
door if it is previously open, and vice versa.
[0111] Subsystem 139 also includes door sensors to detect any
obstacle in the way of closing or opening each door. Upon detection
of any such obstacle, subsystem 139 immediately suspends the door
movement until the obstacle is removed. In this instance, both the
front doors are not fully open because of detected obstacles. This
fact is indicated by lines 871 and 873 marking the extents to which
the respective doors are open and closed. On the other hand, both
the rear doors in this instance are fully open as the corresponding
lines 875 and 877 have moved all the way toward the center.
[0112] It should be apparent by now that the above door control may
also be effectuated by voice command. For that matter, the locking
of the individual doors after they are closed, or activation of the
child lock system may also be realized by voice command.
[0113] Depression of MIRRORS key 232c again invokes the screen of
FIG. 13. Indicators 891, 893 and 895 correspond to the left
rear-view mirror, center rear-view mirror and right rear-view
mirror, respectively. The user may operate indicator device 227 or
229 to point at one of the indicators and drag same (or utilize the
touch-screen capability) to left or right to tilt the corresponding
mirror toward left or right accordingly.
[0114] Subsystem 139 also includes mirror heaters, sensors and
actuators. Based on the above personal preference data, subsystem
139 causes the mirror heaters to defrost the mirrors under certain
specified temperature and weather conditions. Upon the sensors'
detecting a tight parking space for example, subsystem 139 causes
the actuators to fold back one or both external mirrors to avoid
damages. In addition, processor 103 coordinates the action of
electronic transmission/throttle system 325 with that of the mirror
actuators such that when the gear is put in reverse, the actuators
automatically adjust the mirrors to provide a good rear view while
the vehicle is backing up.
[0115] It will be appreciated that subsystem 139 may also
incorporate mirror enhancement techniques for self-dimming the
mirrors or adjusting their clarity, density, opacity, reflectivity,
color, zooming, etc. based on specified light conditions.
[0116] It should be noted at this point that as long as the screen
of FIG. 13 is showing on display 205, the user can conveniently
adjust the windows, doors and/or mirrors at the same time, without
the need of depressing the corresponding access keys to invoke the
screen repeatedly.
[0117] Depression of WIPERS key 232d invokes the screen of FIG. 14.
Subsystem 139 further comprises wipers, wiper actuators and a
windshield debris detection system. The latter includes sensors
which are attached to the windshield of the vehicle to determine
the intensity of a vibration of the windshield. They also determine
the frequency of the vibration whose intensity is above a
predetermined threshold. This threshold accounts for the intensity
of the normal windshield vibration of a moving vehicle. When SMART
WIPE option 903 on the screen of FIG. 14 is selected, processor 103
causes the wiper actuators to operate the wipers in response to a
vibration of above-normal intensity caused by rain, snow, insects,
hail, and such falling on the windshield. The detection of such a
vibration is communicated by the windshield debris detection system
to processor 103, along with the information concerning the
frequency of the vibration. Accordingly, processor 103 varies the
rate of windshield sweeping with the communicated frequency. Thus,
for example, in the SMART WIPE mode, the windshield wiping rate is
adjusted lower when the vehicle stops in the rain, versus the
vehicle running against the rain (i.e., rain drops falling on the
windshield at a higher frequency).
[0118] Other wiper controls are also available on the screen of
FIG. 14. For example, selection of SINGLE WIPE option 907 causes
the wipers to sweep once across the windshield. Selection of CLEAN
WINDOW option 909 causes spraying of cleaning liquid onto the
windshield, followed a predetermined number of wipes. In addition,
the speed of the wipers can be specified by selecting SECONDS
option 911. After option 911 is selected, the user can point and
click at blank 913 to select one of the displayed numbers, thereby
specifying the wiper speed in terms of once so many seconds. Thus,
option 911 is convenient for the user to implement intermittent
wiping. To specify the speed of continuous wiping, the user may
select SPEED option 915. After such an option is selected, the user
can point and click at blank 913 to select one of the displayed
speed levels ranging from slow to fast.
[0119] Depression of TRUNK STORAGE key 232e provides controlled
access to the trunk/storage of the subject vehicle. In addition, it
allows the user to program climate control system 1105 to be
described to controllably cool or heat the trunk/storage to
properly preserve the cargo. Moreover, it enables the user to
instruct processor 103 to open (close) the trunk/storage upon a
shut-off (start-up) of the engine.
[0120] Depression of UNDER HOOD key 232f releases the hood of the
subject vehicle. Through processor 103, various systems may
communicate to the hood mechanism controlling the release of the
hood. For example, when certain fluid levels are detected low or
components under the hood need repair or replacement, upon the
user's agreeing to take a certain remedial action, processor 103
causes the hood mechanism to release the hood in anticipation of
such an action. In addition, each time when the engine is started
and the vehicle is ready to move, processor 103 checks with the
hood mechanism to ensure that the hood has not be accidentally
released.
[0121] Depression of USER'S VIEW key 292g invokes the screen of
FIG. 15. However, this screen is the default screen or "home"
screen on display 205. That is, it automatically comes on after the
vehicle is started, even without depression of key 292g. In
accordance with the invention, the screen of FIG. 15 allows the
user to control and manage certain basic vehicle functions based on
an intuitive approach, without the need of depressing any keys. To
that end, subscreen 950 is used to graphically depict the user's
view of the vehicle. By way of example, displayed items 953 through
959 in subscreen 950 depict the vents, windshield wipers,
instrument panel, audio system, rear-view mirror, seats and
windows/doors in the vehicle, respectively. It should be pointed
out that the relative positions of these displayed items correspond
to those of the depicted components in the actual vehicle. Knowing
the relative positions of the components in the vehicle, the user
can easily identify and point and click at selected items to
efficiently control the corresponding components, and/or access
information concerning them.
[0122] Specifically, when one of items 953 depicting a vent is
selected, processor 103 causes the screen of FIG. 16 (described
below) to be displayed for the user to adjust the air condition.
When one of items 954 depicting a windshield wiper is selected,
processor 103 causes the screen of FIG. 14 (described before) to be
displayed for the user to adjust the wiper function. When item 955
depicting the instrument panel is selected, processor 103 causes
the readings of the speedometer, tachometer, odometer and engine
coolant temperature to be displayed. When item 956 depicting the
audio system is selected, processor 103 causes the screen of FIG.
18 (described below) to be displayed for the user to adjust the
audio system. When item 957 depicting the rear-view mirror is
selected, processor 103 causes the screen of FIG. 13 (described
before) to be displayed for the user to adjust the rear-view mirror
and other mirrors. When one of items 958 depicting a seat is
selected, processor 103 causes the screen of FIG. 16 to be
displayed for the user to adjust the seat. Finally, when one of
items 959 depicting a window/door is selected, processor 103 causes
the screen of FIG. 13 to be displayed for the user to control the
window/door in addition, menu 961 including vehicle components
which are not depicted is provided in the screen of FIG. 15 for the
user's selection. Any selected component from the menu is
highlighted to indicate its selection.
[0123] Accessory keys 219 relate to the functions provided by
accessory control subsystem 143. Depression of SEATS key 219a
invokes the screen of FIG. 16. By pointing and clicking at DRIVER
selection 1005, processor 103 causes display 205 to show the
current configuration of the driver seat, denoted 1007. Similarly,
by pointing and clicking at one of displayed numerals "2" through
"4" next to the word "PASSENGER," processor 103 causes display 205
to show the current configuration of the corresponding passenger
seat.
[0124] The default configurations of the seats are defined by the
personal preference data initially provided by the user. Thus, upon
a start-up of system 100, processor 103 effects the default
configurations. However, by pointing at indicators 1013 and 1015
and dragging same using indicator device 217 or 219 (or using the
touch-screen capability), the user may accordingly adjust the
height of the cushion and the incline of the back support of the
seat, respectively. Nevertheless, for safety reasons not all
configurations of the driver seat are allowed. The arm rest, if
any, can be similarly adjusted. The lumbar support and massage
capabilities and seat temperature can be selected as well. All of
the above seat adjustments may be saved in memory 107.
[0125] As shown in FIG. 17, subsystem 143 includes climate control
system 1105 for effecting the climate control of the vehicle.
System 1105 may utilize additional power resources such as solar or
reserved batteries to provide the necessary cooling/heating.
Climate control system 1105 includes capabilities of providing
air-conditioning/heating local to the driver and passengers, and
also to the overall interior and trunk/storage space. System 1105
also manages air flows in the vehicle, and cooperates with access
control subsystem 139 to achieve window controls. In addition,
system 1105 includes air sensors to detect presence of contaminated
and stale air. When such air is detected, system 1105 automatically
vents it out before its spreading. Furthermore, processor 103
communicates to the user, through display 205, alarms regarding
presence of any hazardous gas or fume in the air, and to what
extent it is consumed by the user. System 1105 may also include
onboard filtration devices to purify contaminated air.
[0126] Depression of CLIMATE key 219b also invokes the screen of
FIG. 16. Vent indicators 1021, 1023, 1025, 1027, 1029 and 1031
indicate the locations of respective vents in relation to the seats
inside the vehicle, denoted 1020. By pointing and clicking at one
of the vent indicators, the user may select the air temperature,
and certain fan movement of the corresponding vent.
[0127] The individual vent settings are stored in memory 107. Thus
upon a start-up of the vehicle, processor 103 receives and analyzes
signals from various thermo-sensors in the vehicle. Based on such
an analysis, processor 103 adjusts the temperatures and air
movement of each vent according to the preferred settings.
[0128] Depression of MENU key 219c provides various menus on
display 205 for selection. Such menus enable the user to access
other features and capabilities of the vehicle which are not
accessible by depressing any other keys on interface 117. This
stems from the physical limit as to the number of keys used,
without overwhelming the user. Thus, any items which are not shown
may be accessed by a selection of an appropriate menu and/or
further selections within the menu using the hot spot touch-screen
capability, ENTER key 215b, or indicator device 227 or 229.
[0129] In addition, user preference selections may be presented by
icon selection bars, hot keys, or function keys, or may be realized
using a set-up screen. Moreover, where further information related
to a displayed option or item would be helpful, an icon or similar
graphical means identified as tips, warnings, etc. for accessing
such information is provided.
[0130] Depression of QUICK TIPS key 219d enables the user to obtain
answers to frequently asked questions (FAQs) and multimedia (i.e.,
audio, text and video) information regarding different features
(e.g., safety features) of the vehicle, and various systems and
subsystems embodied therein. A similar QUICK TIPS arrangement is
described in copending, commonly assigned U.S. patent application
Ser. No. 08/789,934 ("the '934 application"), entitled "Multimedia
Information and Control System for Automobiles," which is hereby
incorporated by reference as if fully set forth herein.
[0131] In this illustrative embodiment, the QUICK TIPS text is
written in well-known hypertext markup language (HTML), and
provides hyperlinks to owner's manual information, pictures,
videos, captions, tips and warnings relating to the subject being
reviewed. In addition, VOICE key 219e to be described may be
selected to have the text read to the user, along with its display.
Moreover, the QUICK TIPS feature may be indicated on display
screens in the form of a selectable icon or option. By selecting
such an option, the user is provided with further information on
the items appearing on the screen.
[0132] It should be noted at this point that the audio medium is an
important medium for presenting information to the user especially
when he/she is driving and needs to keep his/her eyes on the road.
As such, VOICE key 219e is provided to afford an option for voice
presentation of instructions, displayed options, and description of
various systems and features of the vehicle.
[0133] It should also be noted that it is advantageous to have a
sound library stored in memory 107, from which the user is able to
select favorable tones and sound clips to enhance the user's
comprehension while he/she is driving. For example, when a
displayed option is touched by the user on screen 205, a
pre-selected tone is generated through the audio output, indicating
that the option has been selected. Relying on the audio tone
confirmation, as opposed to a visual confirmation, the user while
driving can continually watch the road.
[0134] Depression of VISUAL key 219f provides different system
views, and visual information including warnings, cautions,
hazards, advisories, etc. It also provides a selection of display
systems such as head-up display, projection, three-dimensional
display, holographic and virtual reality systems which may be
provided in the vehicle in combination with or in lieu of display
system 205.
[0135] When coupled with SHIFT key 215a, depression of visual key
219f however activates video system 1107, which enables the user to
play on display 205 selected videos from a video library (e.g., a
compact disk (CD) jukebox) connected to system 100, to receive TV
programs, to record and playback of pictures and video clips from
such sources as video and digital cameras, and to run video files
on weather and traffic downloaded from an external information
source such as the Internet.
[0136] In this illustrative embodiment, the user is provided with
an alternative way of looking up information about the vehicle,
which is arranged by topics in alphabetical order. Depression of
INDEX key 219g enables the user to enter a keyword relating to the
subject of inquiry. Such a keyword may be entered by pointing and
clicking at the appropriate letter keys on a displayed keyboard.
After matching the keyword entry with one of the available topics,
processor 103 causes the information concerning the topic to be
presented in audio, video and/or text. A similar INDEX arrangement
is also described in the '934 application.
[0137] Depression of LIGHTS key 219h enables the user to program
the intensity of individual interior lights depending on the
ambient light condition, and the usage thereof such as the duration
of the respective on-times. The preferred light settings are stored
in memory 107.
[0138] Depression of AUDIO SYSTEM key 219i invokes the screen of
FIG. 18 on display 205. In this instance, audio portion 1205 for
controlling audio system 1109 shares the same screen with radio
portion 1207 for controlling radio receiver 1111. With audio system
1109, the user is able to distribute selected audio signals to
driver and passenger locations. These signals are communicated,
through processor 103, to such subsystems as headsets, earphones,
directional speakers, etc.
[0139] As shown in FIG. 18, portion 1205 enables the user to set
for each driver and passenger sound preferences. With the word
"DRIVER" clicked on and highlighted, the user may use indicator
device 227 or 229 to point at indicator 1245 and move same to
adjust the volume of the audio output, indicator 1247 to adjust the
bass level, and indicator 1249 to adjust the treble level. In
addition, the user may relocate speakers with respect to the user
location to obtain the optimum sound effects. For example, each
speaker is placed on a track and can be driven by an actuator along
the track to reposition it. The relocation of the speakers can be
achieved by pointing at indicators 1251, 1253, 1255 and 1257
corresponding to the respective speakers, and dragging same to the
desired individual locations using indicator device 227 or 229.
Accordingly, processor 103 causes the actuators to physically move
the speakers along the respective tracks to realize the desired
arrangement. Portion 1205 also provides other options such as fader
control, graphic presentation of sound events, and saving of the
preferred audio settings.
[0140] Portion 1207 shows a listing of radio stations for
selection. In accordance with an aspect of the invention, the
frequencies of the selected stations are stored based on geographic
locations such as Los Angeles, Santa Ana and Irvine. As is well
known, the geographic coverage of each station is limited. As a
user travels beyond the coverage, the broadcast from that station
becomes too weak to receive. As such, processor 103 continually
causes a frequency scanner to update the listed stations which are
within the receiving range. The user may save a subset of the
listed stations as his/her favorite stations according to the
current vehicle location.
[0141] Advantageously, by saving certain favorite stations
according to the locations which the user visits often, when the
user travels from one such location to another, he/she can
instantly change, the listing to contain the corresponding favorite
stations. As a result, the otherwise, cumbersome programming of the
stations back and forth between the locations is obviated.
[0142] In the preferred embodiment, the favorite radio station
frequencies are actually stored according to the GPS coordinates of
the locations shown on portion 1207. Navigation system 329
periodically communicates the GPS coordinates of the current
vehicle location to processor 103. The latter compares the
communicated GPS coordinates with those of the locations in
question. As soon as processor 103 determines that one such
location is close to the current vehicle location within a
predetermined range, processor 103 causes the listing of favorite
stations associated with the new location to come on for
selection.
[0143] In accordance with another aspect of the invention, for the
user's convenience, the radio stations are categorized, and listed
according to selected music types such as "country", "rock" and
"classic", and selected program contents such as "talk/news". To
that end, in each radio broadcast, the station transmits auxiliary
data concerning its identity, e.g., an icon, signage and/or call
number representing the station, and the type of program it airs,
e.g., the type of music. In FM stereo broadcast for instance, the
auxiliary data may be transmitted using subcarriers within a
subsidiary communications authorization (SCA) band which lies above
the 53 kHz portion of the station bandwidth allocated to the
transmission of conventional stereo audio signals. A variety of
prior art techniques may be used to modulate these subcarriers to
transmit the auxiliary data. In addition, in accordance with the
technique disclosed in U.S. Pat. No. 5,408,686 issued Apr. 18, 1995
to Mankovitz, the stereo audio portion of the station broadcast
band, rather than the SCA band, may also be used for transmission
of such auxiliary data.
[0144] The auxiliary data transmitted by each station is received
by radio receiver 1111 in the form of a digital message signal. By
decoding such a message signal, receiver 1111 recovers the
aforementioned information concerning the station identity and the
program type. Processor 103 screens the stations for the program
types pre-selected by the user. The desired stations are then shown
on display 205 according to the pre-selected program types.
Illustratively, the stations are represented by the respective
icons or signage, and frequencies. The user may point and click at
(or touch on the screen) one of the icons representing the station
which he/she wants to listen.
[0145] In this instance, the user has selected and is listening to
one of the stations denoted 1271, whose icon is highlighted in a
first color. In accordance with another aspect of the invention,
the previously selected stations, such as stations 1273, 1275 and
1277 are highlighted in a second color. Advantageously, with the
color highlighting, the user can readily back-track the previously
selected stations and settle on one of them, or explore new,
unheard stations.
[0146] It should be noted that from the screen of FIG. 18, the user
may also access other entertainment systems such as cassette, CD,
VCR and TV systems, and the weather band and other functions.
[0147] It should also be noted that the above selection of the
displayed stations may be accomplished by voice command or
depressing preset buttons. In addition, with the proper
authorization, more than one user can save his/her preferred
listing of stations, along with special notes about each station.
In that case, when one wants to change the current listing of
stations, he/she needs to enter a PIN before his/her preferred
listing can be invoked. Moreover, the authorized user may also be
privy to other users' preferred listings, and allowed to choose
therefrom.
[0148] Depression of ANIMATION key 219j enables the user to view on
display 205 animations relating to selected vehicle functions
(e.g., automatic parking) which are being or to be performed. These
animations are instructional, and help the user implement the
functions in question and/or understand the effects thereof.
[0149] Like key 2111 previously described, key 219k is reserved for
future use in this instance.
[0150] Depression of ONLINE key 2191 enables the user to access
on-line systems through such communication links as telephone,
wireless, cellular, satellite, radio spectrum, infrared and sonar
connections. For example, while the vehicle is being operated, the
user may choose to access the vehicle manufacturer's computer to
run extensive diagnostic tests on the vehicle on-line. To that end,
processor 103 establishes a communication link with the
manufacturer computer. After an initial handshake between processor
103 and the manufacturer computer, the latter runs diagnostic
routines on the vehicle systems through processor 103, and elicits
from processor 103 information such as relevant operational
parameters. Test results are generated by the manufacturer computer
and transmitted to processor 103 for display. In addition, the
manufacturer computer can correct or adjust any operational
parameter values during the tests to improve the vehicle's
performance. Similarly, any software upgrade or downloading for the
vehicle systems can be realized through the on-line connection.
Notices of recalls can also be transmitted to processor 103 for the
user's information.
[0151] Depression of PHONE/MODEM key 219m allows the user to obtain
mobile phone, facsimile modem and data modem connections through
cellular and wireless networks.
[0152] Depression of PLANNERS/CALENDAR key 219n invokes reminder
routines for informing the user of past and upcoming events. For
example, certain maintenance reminders may be communicated by the
aforementioned manufacturer computer to processor 103 through an
on-line connection. Instructed by one of the reminder routines,
processor 103 accesses systems such as navigation system 329 to
identify the closest mechanic when the scheduled maintenance is
due.
[0153] Referring back to FIG. 1, turn signal subsystem 147 in
accordance with the invention not only provides the traditional
function of activating turn signals in response to the user's
initiation, but also causes furnishing of intelligence information
on an impending turn. Once processor 103 is interrupted by
subsystem 147 and notified of the impending turn into a particular
direction, processor 103 causes detection subsystem 130 to sense
any obstacles or moving objects in the street to which the vehicle
is turning. Processor 103 then causes display 205 to display such
obstacles and moving objects which may be hidden from the user's
view, along with verbal and visual warnings of any foreseeable
hazards. Thus, with such an assisted turning feature, the risk of
an accident occurring during a turn is substantially reduced.
Furthermore, in automatic driving, processor 103 orchestrates the
actions of steering subsystem 132, brake subsystem 125 and
electronic transmission/throttle system 325 to make a calculated
move around an obstacle, or simply stops the vehicle at the turn to
avoid any collision.
[0154] Speedometer subsystem 149 includes an accelerometer for
evaluating the instantaneous speed of the vehicle. The speed
information is communicated by subsystem 149 to processor 103 for
use in navigation, automatic driving, automatic parking, etc. The
speed information may also be stored with time and GPS information,
and recorded in memory 107 or the aforementioned "black box". The
memory content may be remotely accessed by a police authority, via
a dial-up connection, to determine any speed violation, along with
the associated time, and geographic location based on the GPS
information.
[0155] Safety subsystem 151 includes restraint devices and
air-bags. In accordance with yet another aspect of the invention,
subsystem 151 keeps track of the air-bag deployment and expiration
dates. Advance air-bag expiration and recharge notifications are
transmitted to processor 103. Also transmitted to processor 103 are
data collected by subsystem 151 concerning usage of safety devices,
tire and brake wear, etc., and data on intervals of maintenance
performed on and long term durability of those components. All such
safety information received by processor 103 can be accessed and
displayed at the user's request. In addition, tips and support for
the user's safety in response to certain vehicle malfunctions,
failures or eminent dangers are issued by safety subsystem 151 via
display 205.
[0156] Through processor 103, subsystem 151 cooperates with other
systems in system 100 in certain events. For example, in an
accident, as soon as subsystem 151 informs processor 103 of a
deployment of an air-bag, processor 103 signals engine control
system 319 to halt the engine activity, brake subsystem 125 to
apply emergency braking, and suspension subsystem 129 to stabilize
the vehicle. Processor 103 may further request from navigation
system 329 GPS coordinates identifying the accident scene, and
cause the audiovisual recording facilities in the vehicle to audio-
and video-tape the accident scene, and emergency data to be
transmitted to the authority to obtain help as described
before.
[0157] Clock subsystem 154 provides time and date information.
Relying on such information, processor 103 duly synchronizes system
activities and keeps track of events. For example, utilizing the
temporal information, processor 103 issues the above-described
reminders and notifications in a timely manner. Similarly, the
above-described planner functions such as scheduling maintenance
are made possible with such information.
[0158] Suspension subsystem 129 provides, as mentioned before,
wheel and stability control during the vehicle operation. In
addition, subsystem 129 includes sensors for evaluating the current
road condition, and adjusts the ride and comfort using yaw controls
and dampeners in response to the evaluated condition. It also
provides processor 103 with continuous updates about the road
condition. Utilizing such updates, processor 103 coordinates the
actions of other systems such as steering and brake subsystems to
handle the road in a manner prescribed by the user.
[0159] Wheel subsystem 157 includes sensors for reading tire
pressures, detection of loss of tire traction or tread, etc.
Relevant information is communicated by subsystem 157 to processor
103 to issue necessary alarms including abnormally low tire
pressures. Processor 103 also incorporates the received information
in a concerted effort to achieve ride stability and smoothness.
[0160] Application module 161 which may be located close to master
control interface 117 includes a standard interface such as an
RS232 serial interface. Through this interface, the user or service
personnel may use a conventional computer to update system programs
and personal preference data stored in memory 107, or run
diagnostic routines thereon to identify any system-problems.
[0161] In an alternative embodiment, the standard interface in
module 161, similar to interface 703, accepts IC card 600
previously described. In addition to the aforementioned security
data and personal preference data, space is allocated in card
memory 603 for storing system programs, diagnostic routines and
header information. Such header information includes instructions
for processing of certain contents of memory 603.
[0162] Utilizing a conventional IC card writer connected to a
standard computer which may be remote from the vehicle, the user or
authorized service personnel can revise the security data and
personal preference data in memory 603, and load new programs,
program upgrades and/or diagnostic routines onto the IC card. It
should be noted that any change in the card memory content requires
an initial entry of the aforementioned master key, or other
authorized keys allowing limited access. The IC card may be
inserted into the standard interface of application module 161 when
system 100 is powered down. On power up, after system 100 is
initialized, processor 103 checks the security data in memory 603.
Upon verification of the security data, processor 103 reads the
header information in memory 603, and accordingly causes a transfer
of any new system programs from memory 603 to memory 107 and any
upgrade to the existing programs. In addition, in the presence of
any diagnostic routines in memory 603, processor 103 runs the
routines directly off the IC card. Processor 103 then reads the
personal preference data in memory 603 to effect the preferred
settings' of the vehicle functions.
[0163] The foregoing merely illustrates the principles of the
invention. It will thus be appreciated that those skilled in the
art will be able to devise numerous other systems which embody the
principles of the invention and are thus within its spirit and
scope.
[0164] For example, in the disclosed embodiment, control and
management system 100 is illustratively used in an automobile. It
will be appreciated that a person skilled in the art may also
employ the inventive system in another type of vehicle such as a
boat, an airplane, etc.
[0165] Finally, although control and management system 100, as
disclosed, is embodied in the form of various discrete functional
blocks, the system could equally well be embodied in an arrangement
in which the functions of any one or more of those blocks or
indeed, all of the functions thereof, are realized, for example, by
one or more appropriately programmed processors or devices.
