Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a Continuation Application of U.S.
application Ser. No. 13/768,093, filed on Feb. 15, 2013, which is a
Continuation Application of U.S. application Ser. No. 12/259,768,
filed on Oct. 28, 2008, the disclosures of which are incorporated
by reference herein in their entirety.
BACKGROUND OF THE INVENTION
[0002] 1. Technical Field
[0003] The present disclosure relates to a portable transceiver
communicating with a vehicle control system, more specifically, to
a portable transceiver communicating with a vehicle control system
and including a vehicle locator feature.
[0004] 2. Discussion of the Related Art
[0005] A remote transmitter is typically used in conjunction with a
remote keyless entry (RKE) system to allow a user to lock and
unlock vehicle doors, trunks, control alarm systems, or activate
vehicle features such as remote start, without the need to use a
key. A remote transmitter typically includes a small handheld
transmitter housing that can be mounted to a user's key chain. One
or more small buttons are located on the housing to allow the user
to send desired control signals to a receiver in a vehicle.
[0006] As RKE systems have become integrated with vehicle control
systems, remote transmitters used therewith have been designed to
handle additional non-RKE functions, such as arming/disarming
alarms or remote start of the vehicle's engine, etc. As a result,
such remote transmitters include additional switches or buttons
while retaining the convenient small size of their predecessors.
This, however, has led to remote transmitters having a multitude of
finger-operated buttons thus complicating the operation
thereof.
[0007] In an effort to reduce the proliferation of keys on remote
transmitters, remote transmitters have been designed to include a
user interface, such as a display, in combination with a small
number of buttons.
[0008] In addition to the one-way communication between remote
transmitters and vehicle control systems, remote transceivers have
been developed for bi-directional communication. In particular,
remote transceivers are capable of communicating with vehicle
control or security systems while at the same time are able to
receive status information associated with such systems.
[0009] Forgetting where a vehicle is parked can be a serious
problem in large parking lots such as in shopping malls,
multi-level parking lots, and the like.
[0010] Global Positioning System (GPS) devices are examples of a
radio-based technology that provides direction and distance
information to a pre-determined starting point (waypoint), and
display this information on a display screen, for example.
[0011] GPS is a world-wide radio navigation system formed by a
group of 24 satellites and their associated ground stations. GPS
uses these satellites, appropriately called NAVSTAR (Navigation
Satellite Timing and Ranging), to calculate ground positions. The
basis of GPS operation is the use of triangulation from the
satellites. To triangulate, a GPS receiver measures distance using
the travel time of radio signals. However, to measure travel time,
GPS needs very accurate timing, plus it needs to know exactly where
the satellites are in space. To solve this problem, each of the 24
satellites is inserted into a high enough orbit (12,000 miles) to
preclude interference from other objects, both man-made and
natural, and to insure overlapping coverage on the ground so that a
GPS receiver can always receive from at least four of them at any
given time. In addition, compensation is inserted for any delay the
signal experiences as it travels through the atmosphere to the
receiver.
[0012] With the satellites operating at 12,000 miles above the
earth's surface, they are arranged in strategic positions and orbit
the earth every 12 hours. Each satellite transmits a low-power
radio signal in the UHF frequency range; the frequencies used are
designated as L1, L2, and so forth. GPS receivers listen on the L1
frequency of 1575.42 MHZ. This signal, since it is line-of-sight,
will reach the ground receiver unless it is obstructed by solid
objects, such as buildings and mountains.
[0013] The L1 signal is accompanied by a pair of pseudo-random
signals (referred to as pseudo-random code) which is unique to each
satellite. These codes are identified by the GPS receiver and allow
for the calculation of the travel time from the satellite to the
ground. If this travel time is multiplied by the speed of light,
the result is the satellite range (distance from satellite to
receiver). The navigation information provided by each satellite
consists of orbital and clock data, plus delay information based on
an ionospheric model. Signal timing is provided by highly accurate
atomic clocks. The GPS receiver uses NAVSTAR satellite signals as a
way of determining exact position on earth.
[0014] GPS receivers are intended for navigational use, wherein the
calculated latitude and longitude location is displayed on some
form of geographic or topographical map. These GPS receivers may be
used to locate a vehicle but they can be bulky and require the user
to carry them around along with their RKE system. Further, the user
has to remember to activate the GPS receiver to set the waypoint of
a parked vehicle, for example.

BRIEF DESCRIPTION OF THE DRAWINGS
[0034] A more complete appreciation of the present disclosure and
many of the attendant aspects thereof will be readily obtained, as
the same becomes better understood by reference to the following
detailed description, when considered in connection with the
accompanying drawings, wherein:
[0035] FIG. 1 is a block diagram of a portable transceiver with
vehicle security control and locate features, according to an

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
[0039] In describing exemplary embodiments of the present
disclosure illustrated in the drawings, specific terminology is
employed for the sake of clarity. However, the present disclosure
is not intended to be limited to the specific terminology so
selected, and it is to be understood that each specific element
includes all technical equivalents which operate in a similar
manner.
[0040] Exemplary embodiments of the present invention seek to
provide a portable transceiver with vehicle security control and
locate features. The security control features may include the
arming and disarming of a vehicle alarm, and the locking and
unlocking of the vehicle doors.
[0041] FIG. 1 illustrates a remote transceiver 100 for
communicating with a vehicle control system according to an
exemplary embodiment of the present invention. The vehicle control
system may include security functions such as the arming and
disarming of a vehicle alarm, and the locking and unlocking of the
vehicle doors. As shown in FIG. 1, the remote transceiver 100
includes a central processing unit (CPU) 105 coupled to a memory
110. The memory 110 may include a random access memory (RAM) 115
and a read only memory (ROM) 120. The memory 110 may also include a
database, an electrically erasable programmable read only memory
(EEPROM), or a combination thereof. The CPU 105 processes data and
controls components of the remote transceiver 100. The RAM 115
functions as a data memory that stores data used during execution
of a program in the CPU 105 and is used as a work area. The ROM 120
functions as a program memory for storing a program executed in the
CPU 105.
[0042] A transceiver 125 and an antenna 130 are also coupled to the
CPU 105. The transceiver 125 includes a transmitter and a receiver
housed together for performing transmitting and receiving
functions, respectively. A vehicle locator device 170 is also
coupled to the antenna 130 and the CPU 105. An optional altimeter
180, such as a barometric pressure device, may also be coupled to
the CPU 105.
[0043] An external memory interface 135 may be further coupled to
the CPU 105. The external memory interface 135 may be, for example,
a memory card interface for enabling the remote transceiver 100 to
be upgraded with new functions and/or features associated with the
remote transceiver 100 or a vehicle control or security system. It
is to be understood that the external memory interface 135 could be
a universal serial bus (USB), Ethernet, FireWire, infrared (IR) or
Bluetooth interface for receiving and in some cases requesting
updated functions and/or features to be used by the remote
transceiver 100.
[0044] The remote transceiver 100 includes a button or switch type
input 140 that may include buttons, switches, a keypad, scroll
wheels or a combination thereof, and is employed by a user to
perform certain functions on and with the remote transceiver
100.
[0045] By way of example, the switch type input 140 may include
button 142 used to lock the vehicle, button 146 used to unlock the
vehicle, and button 144 used to find the vehicle. Other buttons
such as buttons for arming and disarming a vehicle alarm (not
shown) may also be included in the switch type input 140.
[0046] A display 155 is connected to the CPU 105. The display 155,
which may be a liquid crystal display (LCD), light emitting diode
(LED) array, organic light-emitting diode (OLED) graphic display,
plasma display, glasses-free three-dimensional (3D)-enabled
display, aluminum gallium arsenide (AlGaAs) LED array, or a liquid
crystal on silicon (LCoS) micro display, may include a dot-matrix
display area 160 or a graphic area for displaying information
thereon in either text or icons.
[0047] The vehicle locator device 170 determines the location
(waypoint) of the transceiver 100 in response to a lock vehicle
command input entered by pressing the lock vehicle button 142, for
example. Because the waypoint is determined whenever the vehicle is
locked, the waypoint represents substantially the location where
the vehicle is parked.
[0048] Further, because the vehicle locator device 170 may not be
capable of accurately measuring elevation, the altimeter 180 may be
used to measure an elevation of the waypoint. The elevation
measurement of the waypoint is particularly important to guide a
person back to their vehicle in a multi-level parking garage, for
example.
[0049] In an exemplary embodiment of the present invention a GPS
locating device may be used as the vehicle locator device 170.
However, other vehicle locator devices may be used such as devices
using radio-frequency (RF) ranging techniques or triaxial
accelerometers, independently or in combination with the GPS
locating device, as will be described below.
[0050] FIG. 2 illustrates a front view of the remote transceiver
100, according to an exemplary embodiment of the present invention.
The display area 160 of the remote transceiver 100 may include a
compass style pointer 200, a set of arrows 210 to display an
elevation direction to the measured waypoint, and distance to the
waypoint indicator 220.
[0051] To find the location of the parked vehicle, for example, the
user depresses the find vehicle button 144 and follows directions
displayed in the display area 155 of the remote transceiver 100.
The directions may also be displayed on an area map.
[0052] The transceiver 100 may also include audible indicators to
assist the user in finding the location of the parked vehicle.
These audible indicators may include a beeping tone of varying
frequency depending on the distance from the vehicle, or an actual
"audio utterance" of directions and remaining distance to the
vehicle.
[0053] The CPU 105 derives, when receiving a find vehicle command,
the displayed directions from directional information of the user's
current location, that is, the location where the find vehicle
button 144 was pressed, to the waypoint.
[0054] The directions may be displayed using the compass style
pointer 200 which would, by using an arrow, direct the user to the
vehicle, the set of arrows 210 would direct the user to go up or
down to find the vehicle, and the distance to the vehicle may be
displayed on the distance indicator 220.
[0055] FIG. 3 shows a vehicle locator device 170 according to an
exemplary embodiment of the present invention. As shown, the
vehicle locator device 170 includes a GPS receiver 310, an
accelerometer device 320, and an RF ranging device. The three
devices shown can be used independently of one another or in any
combination to perform vehicle location functions. For example, if
the user of the vehicle location device according to an embodiment
of the present invention parks his vehicle primarily in an
environment where GPS signals are readily available, such as
outdoors, then a GPS receiver 310 by itself will suffice to receive
signals necessary for processing to guide the user back to his
vehicle, essentially as described above. However, there are
environments where GPS signals from GPS satellites cannot be
received, such as within an indoor parking lot, and use of the GPS
receiver 310 by itself may not be effective in locating the
vehicle.
[0056] According to an exemplary embodiment of the present
invention, an accelerometer device 320 is used to track movement of
the user to guide the user back to a vehicle. The accelerometer
device 320 includes a multi-axis accelerometer 322 and an inertia
reference unit 324. The multi-axis accelerometer can be a triaxial
accelerometer that tracks in three axis the orientation of the
remote transceiver 100. A triaxial accelerometer measures and
outputs acceleration data in three dimensions, e.g., over X, Y, and
Z axis. Acceleration in any one axis can be integrated to obtain
velocity, and the velocity data can be further integrated to obtain
the distance of travel. The triaxial accelerometer includes a
gyroscopic function that measures a shift in the axial direction as
well to thus provide the distance and direction of travel. An
inertia reference unit (IRU) can be used to detect change in
orientation beyond an ordinary amount, such as when a device is
pointed in an axial direction and then pointed in a totally
different direction without axial movement, such as when the device
is put away in the user's purse or pocket.
[0057] FIG. 4 is a flowchart of a process using an accelerometer
and an IRU to direct a user back to his vehicle according to an
exemplary embodiment of the present invention. Upon leaving the
vehicle, the user starts the location tracking process by pressing
on the transmitter. According to one embodiment, the arming of the
vehicle's security system and the start of the location ranging
process can be effected by pressing one button on the transmitter.
Upon initiation, the accelerator starts measuring the distance the
transmitter is moved away from the vehicle in three dimensions
(step 401). Compensation is made to return the remote transceiver
100 to the `true` position when the IRU detects a large change in
orientation of the remote transceiver 100 without substantial axial
movement (step 402), such as when the transmitter is put away,
e.g., in the user's pocket or purse. The accelerometer measures the
distance and direction of each path the user traverses away from
the vehicle (step 403). Data on each change in direction is
recorded (step 404) to facilitate later retrieval by the CPU 105 to
reconstruct the return path for the user (step 405). As each path
is reconstructed for the user, upon the user's pressing of a
`locate` button, the CPU 105 causes the display of the return path
on the display (step 406). The display can be in radial distance,
vertical height, bread crumb trail, or flashing arrow, etc.
[0058] According to another exemplary embodiment of the present
invention, an RF ranging device may be used as the vehicle locator
device 170. The RF ranging device operates by determining a
location by sending out a series of RF pulses of a particular
frequency or frequencies, and measuring received signal strengths
(RSS) to calculate the location.
[0059] RF ranging devices are suitable for indoor use in locations
such as multi-level parking garages in buildings.
Since indoor environments present shadows and reflections of the RF
signals from walls and objects, an RF ranging device may use a
plurality of frequencies, referred to as frequency diversity, to
perform its ranging operations. In an exemplary embodiment of the
present invention, four frequencies may be used such as 315 MHz,
434 MHz, 900 MHz, and 1.6 GHz.
[0060] Furthermore, in another exemplary embodiment of the present
invention, a GPS system, an altimeter, and a transceiver (not
shown) may be installed in the vehicle. When the user presses the
find vehicle button 144, the remote transceiver 100 interrogates,
via the transceiver in the vehicle, the GPS system in the vehicle
to obtain its location.
[0061] The communication between the vehicle and the remote
transceiver 100 is performed using their respective transceivers.
To communicate with each other, the transceivers may use wireless
techniques such as Bluetooth, Wi-Fi, or cellular technologies.
[0062] After the remote transceiver 100 receives the vehicle's
location from the vehicle via the transceiver 125, the CPU 105
derives the directions to the vehicle from the user's current
location to the vehicle's location.
[0063] Having the directions to the vehicle, the user follows the
directions displayed in the display area 155, or the audible
indicators, of the remote transceiver 100 to find the vehicle, as
described above.
[0064] Having described exemplary embodiments of the present
invention, it is to be understood that the invention is not limited
to the disclosed embodiments, but, on the contrary, is intended to
cover various modifications and equivalent arrangements included
within the spirit and scope of the disclosure.
