Vehicle Key Off Load Reduction Via Off-Board Sensor
Abstract
A remote sensing device is utilized to activate boundary alert
sensors in a vehicle to reduce current loading during a key-off
condition. Communication between the remote sensing device and the
vehicle is via a radio-frequency interface that is part of a remote
keyless entry system. The remote sensing device transmits a signal
to the vehicle when an object is detected within a predetermined
range of the remote sensing device. In response to the signal, the
vehicle activates one or more boundary alert sensors. The boundary
alert sensors may include a camera, a radar, and an ultrasonic
sensor. The remote sensing device can be configured to extend a
range of the radio-frequency interface by repeating messages that
it receives.

Description
TECHNICAL FIELD
[0001] This application relates generally to vehicle power
consumption in a key-off condition.
BACKGROUND
[0002] A vehicle includes various systems that may operate during
an ignition-off condition. For example, a theft deterrent system
may be active during the ignition-off condition to detect potential
theft and generate a warning signal. Systems that are active during
the ignition-off condition draw power from a battery which is not
charged during the ignition-off condition. Over time, the active
systems can cause the battery state of charge to fall below a
threshold at which the battery can no longer provide sufficient
power to start the engine. Including more electronic systems that
operate during ignition-off conditions further aggravates this
problem. An obvious solution might be to increase the power
capability of the battery. Such a solution increases the size and
weight of the battery and can affect cost, packaging, and fuel
economy.
SUMMARY
[0003] A vehicle includes a boundary alert sensor and a remote
keyless entry system including a radio-frequency (RF) interface.
The vehicle further includes a controller programmed to, in
response to the vehicle being in an ignition-off state and
receiving a signal from a non-contact object detection sensor
remote from the vehicle via the RF interface indicative of an
object being within a predetermined range of the non-contact object
detection sensor, activate the boundary alert sensor for a
predetermined time interval. The boundary alert sensor includes one
or more of a microphone, a camera, a radar, an infrared sensor, and
an ultrasonic sensor. The controller may be further programmed to
store signals received from the boundary alert sensor for the
predetermined time interval. The vehicle may further include an
alerting device, and the controller may be further programmed to,
in response to receiving the signal, activate the alerting device
for a predetermined amount of time. The alerting device may include
one or more of a light and a horn. The vehicle may further include
a wireless network interface. The vehicle may further include a
display module, and the controller may be further programmed to, in
response to receiving a video signal via the wireless network
interface from the non-contact object detection sensor, activate
the display module and display the video signal on the display
module. The controller may be further programmed to, in response to
receiving a second signal via the RF interface indicative of a
request for activation of the boundary alert sensor, activate the
boundary alert sensor and output data from the boundary alert
sensor via the wireless network interface.
[0004] A remote sentinel device includes an object detection sensor
and a radio-frequency (RF) interface configured to communicate with
a remote-keyless entry system of a vehicle. The remote sentinel
device further includes a controller programmed to, in response to
a signal from the sensor indicative of an object being within a
predetermined range of the object detection sensor, transmit a
message to the vehicle via the RF interface to activate a boundary
alert sensor of the vehicle. The object detection sensor may be a
camera, a radar, an infrared sensor, or an ultrasonic sensor. The
controller may be further programmed to, in response to receiving a
remote sentinel message at the RF interface from a second remote
sentinel device, transmit the remote sentinel message via the RF
interface. The controller may be further programmed to, in response
to receiving a vehicle message at the RF interface from the
vehicle, transmit the vehicle message via the RF interface. The
remote sentinel device may further include a wireless network
interface. The remote sentinel device may further include a camera,
and the controller may be further programmed to, in response to the
signal, activate the camera and transmit video data from the camera
via the wireless network interface.

interface. The controller may be further programmed to, in response
to receiving an activation message to activate the boundary alert
sensor via the wireless network interface, transmit the activation
message to the vehicle via the RF interface to activate the
boundary alert sensor of the vehicle. The controller may be further
programmed to, in response to transmitting the message greater than
a predetermined number of times in a predetermined time interval,
transmit an engine start command to the vehicle via the RF
interface to start an engine of the vehicle. The controller may be
further programmed to, in response to receiving a departure message
from the vehicle via the RF interface indicative of the vehicle
leaving a vicinity of the remote sentinel device, enter a low power
mode to reduce power consumption.
[0006] A method of activating sensors of a vehicle includes
receiving, by at least one controller, a signal indicative of
motion of an object within a predetermined range of a non-contact
sensing device remote from the vehicle during a key-off condition
of the vehicle. The method further includes activating, by the at
least one controller, one or more of the sensors of the vehicle for

Various combinations and modifications of the features consistent
with the teachings of this disclosure, however, could be desired
for particular applications or implementations.
[0013] A vehicle 10 may be configured to provide various security
related features. FIG. 1B depicts a possible vehicle configuration
that includes systems that may be utilized for security related
features. A vehicle 10 may include a theft-deterrent system (TDS)
12. The theft-deterrent system 12 may interface with various
components to detect potential threats and generate alerts to deter
theft of the vehicle 10 and its contents. The theft-deterrent
system 12 may interface with a proximity or motion sensor 14 to
detect movement of the vehicle 10. The motion sensor 14 may be a
vibration sensor that detects vibrations of the vehicle 10 that may
be caused by movement of or contact with the vehicle 10. The
theft-deterrent system 12 may interface with sound or pressure
sensors 16 to detect noise or pressure changes that may be
associated with broken glass or other forced entry. The motion
sensor 14 may include infrared sensors to detect the presence of
persons within the passenger cabin. The theft-deterrent system 12
may interface with door sensors to that indicate when a door is
opened or closed.
[0014] The vehicle 10 may include various devices that may not
traditionally be part of the theft-deterrent system 12 but that may
be useful for enhancing the theft-deterrent function. The vehicle
10 may include various systems and sensors that may be described as
a boundary alert system. The boundary alert system may include any
vehicle sub-system that senses objects within a range or boundary
surrounding the vehicle 10. For example, the boundary alert system
may include one or more cameras 18, 20, 22, 24 that are part of
various vehicle sub-systems. The cameras 18, 20, 22, 24, may be
configured to provide a video signal when activated. The video
signal may be displayed and further processed (e.g., for object
detection). For example, a reverse parking aid (RPA) or backup
monitoring system 26 may include a back-up camera 24 which provides
video of an area behind the vehicle 10. The vehicle 10 may also
include a forward-looking camera 18 that may be part of an Adaptive
Cruise Control (ACC) and Collision Warning (CW) system 28 or a
Lane-Departure Warning (LDW) system 30. Additional side-facing
cameras 20, 22 may be part of a Blind Spot Warning System (BLIS)
32.
[0015] The boundary alert system may include one or more radar
systems 34, 36, 38, 40 to detect objects in various positions
around the vehicle 10. The radar systems 34, 36, 38, 40 may detect
objects around the vehicle 10 and a relative motion of the objects.
The radar system 34, 36, 38, 40 may operate by transmitting an
electromagnetic wave and receiving a reflected electromagnetic wave
from objects in the path of the transmitted electromagnetic wave.
The output of the radar systems 34, 36, 38, 40 may include a
presence of the object, a position of the object relative to the
vehicle 10, and a relative velocity of the object. The ACC/CW
system 28 may include a radar 34 that provides information
associated with objects located in an area to the front of the
vehicle 10. The BLIS 32 may include side-facing radars 36, 38. The
backup-monitoring system 26 may include a rear-facing radar 40. The
radar systems 34, 36, 38, 40 may detect motion of objects at a
greater range than the proximity sensors 14 of the theft deterrent
system 12. The radar systems 34, 36, 38, 40 may be configured to
detect objects in front of the vehicle, behind the vehicle, and
along the sides of the vehicle. The radar systems 34, 36, 38, 40
may be laser-based radar systems (e.g., lidar).
[0016] Electronic modules in the vehicle 10 may communicate via a
vehicle network 60. The vehicle network 60 may include a plurality
of channels for communication. One channel of the vehicle network
60 may be a serial bus such as a Controller Area Network (CAN). One
of the channels of the vehicle network 60 may include an Ethernet
network defined by Institute of Electrical and Electronics
Engineers (IEEE) 802 family of standards. Additional channels of
the vehicle network 60 may include discrete connections between
modules and may include power signals from the vehicle battery 54.
Different signals may be transferred over different channels of the
vehicle network 60. For example, video signals may be transferred
over a high-speed channel (e.g., Ethernet) while control signals
may be transferred over CAN or discrete signals. The vehicle
network 60 may include any hardware and software components that
aid in transferring signals and data between modules.
[0017] The boundary alert system may include an ultrasonic sensor
42. The ultrasonic sensor 42 may be part of the backup monitoring
system 26 or a front parking aid system. The ultrasonic sensing
system 42 may detect objects within a predetermined range of the
vehicle 10. The ultrasonic sensing system 42 may emit
high-frequency sound waves and detect a signal reflected from an
object.
[0018] The sensors associated with the boundary alert system may be
referred to as boundary alert sensors. The boundary alert system
may include various warnings and indicators. The warnings and
indicators may include visual indicators such as lamps and a
display 44. The warning and indicators may include one or more
audible indicators 46. The audible indicators 46 may include
speakers, buzzers, alarms, and horns. The warnings and indicators
may include tactile indicators 48 that cause a vibration (e.g.,
steering wheel vibration). Various control elements such as relays
or switching devices may be associated with the warning and
indicators to allow control modules to modify the state of the
warnings and indicators. The warnings and indicators may be
configured to be sensed by persons external to the vehicle 10. For
example, the vehicle 10 may include headlights 50 that may be
utilized as an indicator. Additional lights that may be used
include tail lights, brake lights, and dome lights. Some warnings
and indicators may be configured to be sensed by persons that are
in the vehicle 10.
[0019] The display 44 may be configured to display pictures and
video from the cameras 18, 20, 22, 24. The display screen 44 may be
located in a dashboard of the vehicle 10. In some configurations,
the display screen 44 may be configured to display video from an
active camera under certain conditions. For example, when a
transmission of the vehicle 10 is in a reverse gear, video images
from the backup camera 24 may be displayed. In some configurations,
the video from the cameras 18, 20, 22, 24 may be displayed when the
vehicle 10 is in a parked condition (e.g., transmission gear is
PARK). In some configurations, the video signal may be displayed
during a parking maneuver. In some configurations, the video signal
that is displayed may be selected by an operator. In some
configurations, display of video on the display 44 may be inhibited
when the vehicle 10 is moving. In some configurations, the display
screen 44 may be a touch screen device configured to accept input
data and commands. In some configurations the display 44 may be a
touchscreen display configured to allow user input by touching
locations on a screen of the display.
[0020] In some configurations, the theft-deterrent system 12 may be
activated when the vehicle 10 is locked. Locking of the vehicle 10
may be performed in a variety of ways. For example, inserting a key
into the locking mechanism and rotating in a predetermined
direction may lock the vehicle 10 and activate the theft deterrent
system 12. In some configurations, the sensors of the
theft-deterrent system 12 may be activated and monitored when the
vehicle 10 is unlocked and unarmed.
[0021] The vehicle 10 may include one or more microphones 62. The
microphone 62 may be located in the passenger cabin to receive
sound from inside the vehicle 10. In some configurations, the
microphone 62 may be configured to receive sound from outside of
the vehicle 10. The microphone 62 may be incorporated into the
boundary alert system to record sound during an event. Usage of the
microphone 62 to record sounds in and around the vehicle may be
limited by state laws.
[0022] The vehicle 10 may include a wireless communications module
56 to communicate with devices remote from the vehicle 10. The
wireless communications module 56 may include an onboard modem
having an antenna to communicate with off-board devices. The
wireless communications module 56 may be a cellular communications
device to enable communications via a cellular data network. The
wireless communications module 56 may be configured to communicate
according to the IEEE 802.11 standard. The wireless communications
module 56 may be configured to utilize Bluetooth low energy (BTLE),
dedicated short-range communication (DSRC) or any other standard
wireless communication methods. The wireless communications module
56 may be configured to establish communication with a nomadic
device (e.g., phone, tablet, computer). The nomadic device may be
connected to an external network. The controller 58 may be
programmed to implement an appropriate communications protocol in
hardware and software that is compatible with a selected mode of
wireless communication.
[0023] The boundary alert sensors may be activated and monitored
via the wireless communications module 56. The operator may
activate the boundary alert sensors using a nomadic device and
establishing communication with the vehicle 10. Sensor data from
the boundary alert sensors may be transmitted to the nomadic
device.
[0024] The vehicle 10 may include a keyless entry system 52 that
may referred to as a remote keyless entry (RKE) system or a Passive
Entry-Passive Start (PEPS) system. The keyless entry system may
include a low-frequency (LF) radio transceiver for PEPS fob
detection and an ultra-high frequency (UHF) transceiver for
communicating signals to and from a RKE key fob or a PEPS key fob.
The keyless entry system 52 may utilize a radio frequency (RF)
communications interface to wirelessly transmit and receive signals
from a key fob 100. FIG. 1A depicts a key fob 100 that may be
configured to interface with the keyless entry system 52 of the
vehicle 10. The RF communication interface may be configured to
provide limited distance communications with the vehicle 10. That
is, the key fob 100 may directly communicate with the keyless entry
system 52 when the key fob 100 is located within a predetermined
distance of the vehicle 10. The RF communication interface may
include associated circuitry and an antenna. The RF communication
interface may include an associated controller to decode the RF
messages and interface with the vehicle networks 60 to transfer the
received message data to other modules. The associated controller
may also receive information from the vehicle networks 60 to encode
and send over the RF communication link.
[0025] The key fob 100 may include one or more buttons 102, 104,
106, 108 that perform a specific function. In some configurations,
a first button 102 may cause transmission of an RF signal to lock
one or more doors of the vehicle 10 and activate the
theft-deterrent system 12. A second button 106 may cause
transmission of an RF signal to unlock one or more of the doors of
the vehicle 10 and deactivate the theft-deterrent system 12. A
third button 104 may cause transmission of an RF signal to open a
trunk or hatch of the vehicle 10. A fourth button 108 may cause
transmission of an RF signal to start an engine of the vehicle 10.
Various combinations and functions of the key fob buttons 102, 104,
106, 108 are possible and the examples cited are merely exemplary.
A key fob 100 may be configured with more or fewer buttons than
depicted and described. In configurations in which the key fob 100
is a smart PEPS key fob, the functions (e.g., lock, unlock) may be
performed by the key fob 100 being in proximity with an appropriate
vehicle zone or depressing release switches mounted on vehicle
closures (e.g., handles, decklid, or other structures).
[0026] In some configurations, the key fob 100 may receive signals
from the vehicle 10 and provide a display 110 or other indication
(e.g., vibration, light) of the signal from the vehicle 10.
Usefulness of this feature may depend upon being within the
predetermined distance of the vehicle 10 over which the RF
communication interface is effective.
[0027] The theft-deterrent system 12 may monitor the one or more
proximity or motion sensors 14. The motion sensors 14 may detect
motion of the vehicle 10 or motion of an object in the passenger
cabin. The theft-deterrent system 12 may include a controller to
monitor the motion sensors 14 to trigger the audible indicator 46
under certain conditions. For example, the detection of motion of
the vehicle 10 may activate the horn continuously or with a
predetermined on-off pattern. In some configurations, the detection
of vehicle movement may trigger a controller to record video from
one or more of the cameras 18, 20, 22, 24. In some configurations,
the system may be configured to capture video before the actual
alarm trigger to capture events leading up to the triggering of the
alarm. In such a configuration, one or more of the cameras 18, 20,
22, 24 may be activated as part of the theft-deterrent system
12.
[0028] The theft-deterrent system 12 may draw power from a vehicle
battery 54. As the theft-deterrent system 12 is active during
key-off conditions, the amount of power used by the theft-deterrent
system 12 should be minimized to prevent discharging the vehicle
battery 54 below a predetermined level. As current is provided by
the battery 54 (e.g., battery is discharging) a state of charge of
the battery may decrease. The state of charge may represent an
amount of energy stored in the battery. As the state of charge
decreases, the battery voltage may decrease. As the state of charge
and battery voltage decrease, the ability of the battery 54 to
provide current is reduced. A prolonged interval without a key-on
cycle combined with insufficient engine on-time or alternator
current production may cause the vehicle battery 54 to discharge to
a level at which sufficient current is no longer available to start
the engine. It may be useful to reduce a key-off current load (KOL)
during key-off/ignition-off situations to prevent a condition in
which the engine cannot be started.
[0029] Although there may be benefit to utilizing the boundary
alert sensors to enhance the theft-deterrent function, there are
potential limitations. A system configured to utilize the
additional cameras and sensors of the boundary alert system to
record video and sensor data may increase the KOL. There may be a
trade off in earlier collection of data and maintaining the KOL at
a low level. For example, the cameras 18, 20, 22, 24 and other
sensors may be powered on periodically or continuously during the
key-off condition thereby increasing the KOL of the vehicle 10. The
additional KOL associated with the boundary alert sensors may
increase the risk that the engine cannot be started.
[0030] In addition to enhancing vehicle security, some
configurations may utilize the boundary alert sensors for other
purposes. The vehicle 10 may include a surveillance mode in which
video from the cameras 18, 20, 22, 24 is displayed on the display
screen 44. The surveillance mode may be useful for law enforcement
activities. The surveillance mode may be enabled when the vehicle
10 is in a parked condition to avoid distraction while driving. The
operator may select to enter the surveillance mode. During a
key-off condition, the boundary alert sensors may be activated to
detect moving objects near the vehicle 10. The movement may cause
the video signal from one of the cameras 18, 20, 22, 24 to be
displayed on the display screen 44.
[0031] In some configurations, the vehicle 10 may include a
boundary alert function. The boundary alert function may operate by
detecting movement in a particular area near the vehicle 10. For
example, the front-facing radar 34 may be activated to detect
movement in the area in front of the vehicle 10. When movement is
detected, the audible indicator 46 or the visual indicator (e.g.,
lights 50) may be activated to alert persons nearby. Potential
usage of the boundary alert function may be in a campground. The
vehicle 10 may be placed facing a tent or other shelter. The
boundary alert function may be activated to provide a virtual
boundary around the shelter for which movement is to be detected.
This may provide a warning to those inside the shelter as to
intruders present in the area. This feature may also provide
protection near a house or other structure. For example, when
parked in a driveway of a house, the vehicle 10 may be facing a
garage or shed.
[0032] These additional functions (surveillance and boundary alert)
may be operated during an ignition-off condition and thereby
increase the KOL of the vehicle 10. As additional boundary alert
sensors are activated during the ignition-off condition, the
potential for draining the vehicle battery 54 increases. Operating
for prolonged periods with the boundary alert sensors and alert
features activated may increase the KOL and increase the risk of a
no-start condition.
[0033] FIG. 1A depicts a remote sensing device 200 that may be
configured to interface with the vehicle 10. In order to minimize
the risk of increasing KOL, it may be useful to utilize one or more
remote sensors 200. The remote sensor 200 may be referred to as a
remote sentinel (RS) device or module. The remote sentinel device
200 may include one or more object sensors 202 to detect objects
near the RS device 200. The RS device 200 may also include a camera
204 to record video. The object sensor 202 may include a proximity
sensor to detect the presence of objects near the RS device 200.
The object sensor 202 may include an infrared sensor. The object
sensor 202 may include a laser-based sensor. The object sensor 202
may include a radar system. The object sensor 202 may include any
form of touchless sensor capable of detecting a nearby object. The
object sensor 202 may be configured to detect the presence of the
object as well as motion of the object.
[0034] The RS device 200 may include a controller 210 to process
and manage signals within the RS device 200. The RS controller 210
may interface with the object sensors 202 and process signals from
the object sensors 202. The RS controller 210 may include volatile
and non-volatile memory for storing data.
[0035] The RS device 200 may interface with the vehicle 10 to
enhance the detection of objects near the vehicle 10. The RS device
200 may be configured to detect an object and activate the vehicle
10 boundary alert sensors. In this manner, the boundary alert
sensors of the vehicle 10 do not draw power from the vehicle
battery 54 during the ignition-off condition until activated by the
RS device 200. The boundary alert sensors may be activated when the
vehicle 10 receives a signal from the RS device 200 that an object
has been detected nearby. An added benefit of this configuration is
that the RS device 200 can extend the detection range around the
vehicle 10 and enhance the vehicle security function. Further, the
direction in which objects are detected may be changed by adjusting
an orientation of the RS device 200. Multiple RS devices 200 may be
placed in various positions around a vehicle to provide detection
zones that may not be possible with the vehicle 10 alone. For
example, boundary alert sensors in the vehicle 10 may be obstructed
by objects. The RS devices 200 may be placed in a position to avoid
the obstructions. Further, the boundary alert sensors of the
vehicle 10 may only activate upon detection of activity that is
within the range of the sensors which may cause the sensor to miss
capturing a portion of the activity. The off-board RS device 200
allows the boundary alert sensors of the vehicle 10 to be fully
active before a potential thief has entered the vicinity of the
vehicle 10 and its boundary alert sensors.
[0036] The RS device 200 may include a communications module 206
configured to communicate with the vehicle 10, additional RS
devices 200, and other compatible devices (e.g., computers, phones,
and tablets). The communication module may include wired and
wireless communications. For example, the wired communications may
include an Ethernet connection defined by the IEEE 802 family of
standards. The wired communication interface may provide
communication with other devices when connected. The communication
module 206 may include a wireless network interface defined by the
IEEE 802.11 standard. The wireless network interface may also
employ other wireless communications solutions such as Wi-Max. The
wireless network interface may also include a Bluetooth interface.
A communication protocol that defines messages and message timing
may be defined for communicating between the various devices. The
RS controller 210 may interface with the communications module 206
to manage and control the operation of the communications module
206. The RS controller 210 may process messages received via the
communications module 206 and may provide messages to be
transmitted via the communications module 206. The RS device 200
may be configured to communicate with the vehicle 10 and remote or
nomadic devices (e.g., phones, tablets, computers).
[0037] The communications module 206 may include a cellular
communications device to enable communications via a cellular data
network. The communications module 206 may be configured to
establish communication with a nomadic device (e.g., phone, tablet,
computer). The RS controller 210 may be programmed to implement an
appropriate communications protocol in hardware and software that
is compatible with a selected mode of communication.
[0038] During a key-off condition of the vehicle 10, the keyless
entry system 52 may continue to be active. To provide
communications during a key-off condition of the vehicle 10, the RS
device 200 may include an RF communications interface 208 that is
compatible with the keyless entry system 52 of the vehicle 10. The
RF communications interface 208 may be configured to communicate
with one or more RS devices 200 and the vehicle 10. The RS
controller 210 may be coupled to the RF communications interface
208. The RS controller 210 may implement a message protocol for RF
communications with the vehicle 10.
[0039] The RS device 200 may be placed or mounted at a distance
from the vehicle 10. A maximum distance from the vehicle may be a
function of the RF communication range and the RF signal
transmission strength. The RS device 200 may monitor an area or
zone for objects or movement. In some configurations, the RS device
200 may monitor a configurable zone. For example, the RS device 200
may be mounted to a wall and objects or movement may be detected in
a predetermined area in front of the wall. The monitoring zone may
include a predetermined arc radiating from the RS device 200 for a
predetermined distance. In some configurations, the RS device 200
may monitor an area around the RS device 200. For example, an
electric motor having a shaft coupled to the object sensor 202 may
rotate the object sensor 202 to enable complete circular coverage
about the RS device 200.
[0040] The RS device 200 may be mounted in a variety of ways. The
RS device 200 may include a magnetic surface that is capable of
coupling to a metal surface. The RS device 200 may include an
adhesive backing for mounting. The RS device 200 may include slots
for straps, pins, and tabs that allow for additional mounting
options. The RS device 200 may be mounted on a post.
[0041] The RS device 200 may be coupled to a power source. The
power source may be a battery which may be rechargeable or
replaceable. In some configurations, the power source may include a
solar panel to recharge the battery. In some configurations, the
power source may be a standard electrical outlet. The RS device 200
may include additional circuitry to convert from alternating
current (AC) inputs to direct current (DC) levels that may be
utilized by the RS device 200. The power source may be electrically
coupled to the various components of the RS device 200 and provide
appropriate voltage and current levels to power the components.
[0042] The RS device 200 may be camouflaged to blend in with the
environment in which it is placed. A housing of the RS device 200
may be formed in a variety of ways depending on the application.
The RS device 200 may be disguised within other common objects in
the environment. For example, the RS device 200 may be incorporated
into a light bulb base such that power is drawn from the light bulb
socket. The RS device 200 may include a light bulb socket to permit
a light bulb to be installed (e.g., RS device 200 electrically in
series with the light bulb and original socket). Such a
configuration disguises the presence of the sensor and provides a
motion-activate light.
[0043] The RS device 200 may further be configured with a camera
204. The RS controller 210 may interface with the camera 204 to
receive video signals. The RS controller 210 may provide controls
signals to the camera 204 to manage operation of the camera 204.
Upon receiving signals from the object sensor 202 indicative of an
object in the monitoring zone, the RS controller 210 may activate
the camera 204 and transmit video information over the
communication module 206. In some configurations, the camera 204
may be utilized as the object sensor 202. That is, the object
sensor 202 may be a camera. The RS controller 210 may process video
signals from the camera 204 to detect the presence of objects. The
RS controller 210 may be configured to store video information in
controller memory. The video information may be transmitted via the
communication module 206 for a predetermined period of time. In
some configurations, the video may be transmitted until the object
is no longer detected in the monitoring zone. The video may be
received by the vehicle 10 and displayed in the vehicle 10 to
provide occupants with visual feedback in areas that may not be
visible from the vehicle 10. The video may also be transmitted to
the nomadic device. Such a configuration may allow a surveillance
function in a vehicle 10 that is parked with the ignition off
without increasing the KOL.
[0044] The RS controller 210 may monitor signals from the object
sensor 202 to detect the presence of an object in the monitoring
zone. When an object is detected in the monitoring zone, the RS
controller 210 may initiate transmission of a signal or message via
the RF communication interface 208 indicative of an object near the
RS device 200. If the vehicle 10 is in RF communication range, it
may receive the signal or message via the keyless entry system 52
interface. Upon receiving the message, the vehicle 10 may activate
the boundary alert sensors.
[0045] The RS device 200 may be configured to allow an operator to
activate a boundary alert sensor on the vehicle 10 via the nomadic
device in the absence of any detected activity. For example, an
operator may, through the nomadic device, activate the camera in
the vehicle to check conditions near the vehicle 10. The operator
may activate the camera to view snow accumulation, status of trash
pick-up, or other routine uses unrelated to theft risk. The RS
device 200 may communicate to the vehicle 10 via the communication
module 206 and the RF interface 208. For example, the RS device 200
may wake the vehicle over the RF interface 208. The vehicle 10 may
transmit video data via the wireless communications module 56.
Depending on the particular configuration, the video data may be
relayed by the RS device 200 or may be received by a nomadic
device.
[0046] In some configurations, the vehicle 10 may be configured to
transmit an arrival message via the RF communication interface 208
when entering a vicinity of the RS device 200. In response to
receiving the arrival message, the RS device 200 may wake up and
operate as described. Upon leaving the vicinity of the RS device
200 (e.g., drive-off of the vehicle 10), a departure message may be
transmitted. In response to receiving the departure message, the RS
device 200 may enter a low-power mode to prolong battery life. Upon
returning to the vicinity of the RS device 200, the vehicle 10 may
transmit the arrival message. The RS device 200 may be configured
to wake up upon receiving the arrival message from the vehicle
10.
[0047] In response to receiving the signal indicative of the object
near the RS device 200, a vehicle controller 58 may activate the
boundary alert sensors. The vehicle controller 58 may include
volatile and non-volatile memory for storing data from the boundary
alert sensors. For example, in a configuration in which the
boundary alert sensor is a camera 18, 20, 22, 24, the RS device 200
may allow earlier detection of the object so that video footage may
be obtained at an earlier time. The vehicle controller 58 may
activate the cameras 18, 20, 22, 24 in response to receiving the
signal indicative of the object near the RS device 200. Video may
be captured before the object causes activation of the
theft-deterrent system 12. In this manner, video may be captured of
the object that triggered the theft-deterrent system 12. In some
configurations, the RS device 200 may not be placed within a line
of sight of the vehicle 10. The RS device 200 may be placed around
corners to detect objects approaching from various directions. The
use of the RS device 200 may extend the range of the vehicle
boundary alert system.
[0048] The use of the RS device 200 in conjunction with the
boundary alert sensors of the vehicle 10 may find use in military
or law enforcement applications. Various configurations of the RS
device 200 and the vehicle 10 may include surveillance and
monitoring capabilities. For example, a police car may be parked on
a street a distance from an intersection. One or more RS devices
200 may be placed on a cross street running perpendicular to the
street in which the police car is parked. The RS device 200 may
detect vehicles approaching on the cross street. The RS devices 200
may transmit a signal to the police car via the RF communications
interface 208.
[0049] The reception of the signal from the RS device 200 may also
trigger activation of one or more of the radar systems 34, 36, 38,
40. The vehicle controller 58 may activate the radar systems 34,
36, 38, 40 in response to receiving the signal indicative of the
object near the RS device 200. The police car may include an
additional radar system configured for speed limit enforcement.
When receiving the signal from RS device 200 that an object is in
range, the additional radar system may be triggered to measure the
speed of approaching vehicles. In addition, cameras 18, 20, 22, 24
in the 10 and the RS device 200 may be triggered to record video.
The vehicle controller 58 may store video in non-volatile
controller memory for later retrieval and processing. In the event
of a speed violation, video of the driver and the vehicle may be
available as further evidence. Such a configuration may be
beneficial as the additional radar system is not detectable until
the approaching vehicle is near, thereby rendering radar detection
devices less useful.
[0050] Other potential applications may include campsite security.
FIG. 2 depicts a configuration of vehicle and RS devices 200 that
may be used for a campsite security function. The vehicle 10 may be
parked near a campsite 300. One or more RS devices 302, 304 may be
placed around the campsite 300 to provide monitoring about the
campsite 300. The RS devices 302, 304 may communicate with the
vehicle 10 when movement of an object is detected around the
campsite 300. For example, a first RS device 302 may monitor a
first zone 306. A second RS device 304 may monitor a second zone
308. The first zone 306 and the second zone 308 may overlap. In
addition, one or more of the first zone 306 and the second zone 308
may include the campsite 300 or the vehicle 10. In response to
signals from the RS device module 302, 304, the vehicle 10 may
record video, turn on headlights 50, or activate the audible
indicator 46 to generate an audible alarm signal. Such a response
may warn those at the campsite 300 as to movement around the
campsite as well as ward off any potential intruders.
[0051] In some configurations, the RS device 200 may communicate
directly with the nomadic device of the operator to notify the
operator of any detected activity in the vicinity of the RS device
200. The operator may then elect to communicate with the vehicle 10
via the nomadic device to enable functions such as perimeter
lighting, or camera/sensor activation. The nomadic device may
include a processor that executes an application configured to
interface with the RS device 200. The nomadic device may be used to
configure operation of the RS device 200, receive status
information from the RS device 200, and transmit commands to the RS
device 200 intended for the RS device 200 and the vehicle 10.
[0052] The previous example was with reference to a campsite but
the concept is easily extended to other applications. Other
configurations may be used for household or property security. For
example, the campsite 300 may be a house, a garage, or other
structure or area for which monitoring is desired. One or more RS
devices 200 may be placed in various locations around a house. For
example, one RS device 200 may be placed in a back yard and another
RS device 200 may be place in a front yard. The vehicle 10 may be
parked in a driveway or in the street. The RS devices 200 may each
monitor a predetermined zone near the house. As objects are
detected, the RS devices 200 may transmit signals to the vehicle
10. When the vehicle 10 receives message that objects are detected
by the RS devices 200, additional sensors and cameras of the
vehicle 10 may be activated. In a household application, the
signals may be integrated with a home security system via the
keyless entry system 52 interface or the wireless communication
interface 56. Video recorded by the vehicle 10 may be transferred
over the wireless communication interface 56 to a computer or other
device connected to the same network. The controller 58 may be
programmed to output status via the remote communications module in
response to receiving the object detected message from the RS
devices 200. For example, an operator may receive status via a
cellular network whenever the vehicle 10 is activated by the
detection of an object.
[0053] Advantages of utilizing the RS devices 200 include earlier
warning of moving objects (e.g., persons or vehicles) near the
vehicle 10. The system also extends the sensing range further from
the vehicle 10 so that movement in sensitive zones may be
identified sooner. In addition, the boundary alert sensors of the
vehicle 10 may be utilized without the vehicle in a key-on
condition which reduces noise and reduces fuel consumption.
Further, the boundary alert sensors may be effectively utilized
without excessive KOL that may drain the battery. The RS device 200
may activate the vehicle boundary alert sensors via an RF
transmission to the vehicle keyless entry system 52 since the RF
receiver may be configured to be in listen mode when the vehicle is
in a stationary or ignition-off condition.
[0054] In some configurations, the RS device 200 may include a
repeater function. In some configurations, the RS devices 200 may
be placed at increasingly further distances from the vehicle 10. In
such configurations, each RS device 200 may be capable of receiving
signals from the other RS devices 200 and re-transmitting them to
the vehicle 10. This extends the communication range of the RS
devices 200 and key fobs 100 and also extends the distance from the
vehicle 10 that may be monitored.
[0055] The repeater functionality may be useful in a parking lot
application. A parking lot may be configured with multiple RS
devices 200. FIG. 3 depicts a diagram for a possible configuration
of RS devices 200 for a parking lot application. For example, a
first RS device 400 may be located in the parking lot. The first RS
device 400 may have a communication range that is effective in a
first zone 412. In this example, the vehicle 10 is in this first
zone 412 so that the first RS device 400 may communicate directly
with the vehicle 10. The vehicle 10 may have a communication range
that is effective within a second zone 414 such that the first RS
device 400 is within the second zone 414. A second RS device 402
may be located a distance from the first RS device 400. The second
RS device 402 may be located within the first zone 412 so that
messages may be exchanged with the first RS device 400. The second
RS device 402 may have a communication range that is effective
within a third zone 416. A third RS device 404 may be located
within the third zone 416 so that messages may be exchanged between
the second RS device 402 and the third RS device 404. The third RS
device 404 may have a communication range that is effective in a
fourth zone 418. Within the fourth zone 418 an operator may utilize
a remote computing device 406 having a communication range that is
effective in a fifth zone 420. Additionally, the operator may be
carrying the key fob 100 that has a communication range that is
effective in the fifth zone 420. The third RS device 404 may be
within the fifth zone 420. Note that the communication range of the
vehicle (e.g., second zone 414) does not include the second RS
device 402, the third RS device 404, the key fob 100, or the remote
computing device 406. Note that additional RS devices may be placed
in various configurations. In some configurations, a number of RS
devices 200 may be placed in a grid such that a vehicle 10 may
communicate with at least one of the RS devices 200. The
communication zones are depicted as circles but the actual shape of
the communication zone may vary based on terrain, antenna
characteristics, and structures in the area.
[0056] A communication protocol for signals transmitted over the RF
interface may be defined. Each of the RS devices 200 and the
vehicle 10 may be assigned a unique identifier. Each RS device 200
may monitor the communication traffic within its communication
range. In some configurations, the vehicle 10 may transmit an
acknowledge message in response to receiving a message from the RS
device 200. The RS devices 200 may monitor the acknowledgement
messages to determine if the message should be relayed. If an RS
device 200 receives a message from another RS device 200 but does
not see an acknowledgement from the vehicle 10 in a predetermined
time, the RS device 200 may attempt to retransmit the message from
the other RS device 200. In this manner, the message may be
repeated until it reaches the vehicle 10. Upon receiving the
vehicle acknowledgement, the RS device 200 may re-transmit the
acknowledgment message to relay it to the source RS device 200.
Other communication protocols for relaying the messages are
possible.
[0057] As an example of the parking lot repeater functionality, the
operator may desire to start the engine using the key fob 100. The
user may press a button the key fob 100 associated with a remote
start. The key fob 100 may transmit a first RF signal over the
keyless entry system interface. In this case, the first RF signal
422 may only be received by the third RS device 404 as it is the
only RS device in the fifth zone 420. The third RS device 404 may
receive the first RF signal 422 and may wait a predetermined time
to determine if the first RF signal 422 was received by the vehicle
10. In this case, the vehicle 10 is not within the fifth zone 420
and will not receive the first RF signal 422. The third RS device
404 may then transmit the first RF signal 422 as a second RF signal
424. As the second RS device 402 is within the fourth zone 418, the
second RS device may receive the second RF signal 424. The second
RS device 402 may receive the second RF signal 424 and repeat it by
outputting a third RF signal 426 that may be received by the first
RS device 400. The first RS device 400 may receive the third RF
signal 426 and repeat it by outputting a fourth RF signal 428 that
may be received by the vehicle 10. The transfer of data between the
vehicle 10 and the remote computing device 406 and the key fob 100
may be bi-directional. Messages from the vehicle 10 to the key fob
100 may follow a path in the opposite direction. In this example,
the vehicle 10 may receive the fourth RF signal 428 and start the
engine.
[0058] The relay function may also include relaying data via the
wireless network interface of the communications module 206. For
example, the operator may issue a command from a remote computing
device 406 (e.g., computer, phone, or tablet) to provide video from
the vehicle 10. The remote computing device 406 may be configured
to output an RF signal 430 with the appropriate command. The RF
signal 430 may be propagated through the RS devices 400, 402, 404
as described previously. The vehicle controller 58 may receive the
command and activate one or more cameras 18, 20, 22, 24 on the
vehicle 10. The video signals may be recorded on the vehicle 10. In
some configurations, the video may be transmitted through the
wireless communication module 56. The video data may be routed to
the remote computing device 406 through the communications module
of the RS devices 400, 402, 404. The video may be received by the
remote computing device 406 and displayed. The effective range of
the wireless network interface may be different from the RF
communication interface. In FIG. 3, the wireless network in
depicted with dashed lines. Propagation of the wireless network
messages may be performed in any suitable manner.
[0059] The relay function of the RS device 200 extends the range of
the RF interface of the keyless entry system 52. Extending the
range of the RF interface allows for additional functionality. For
example, a vehicle 10 may be remote started from a further distance
when repeater functionality is deployed. Alarm signals from the
vehicle 10 may be received over longer distances which enhances the
alarm function. In addition, video from the vehicle may be received
over the network via the communications modules 206 to enable an
operator to view conditions around the vehicle 10.
[0060] The repeater function for a parking lot application may
include multiple vehicles and multiple operators. The example
described considered only one vehicle 10, but the concept is easily
extendable to multiple vehicles. Additional data transmission
security features may be incorporated into the RS devices 200 to
ensure that the signals transferred are secure.
[0061] The RS device 200 may be configurable over the Bluetooth or
wireless network established by the communications module 206. When
a control device that includes Bluetooth is in range, the RS device
200 may establish communication with the control device. In some
configurations, camera positioning and focusing may be adjusted. In
some configurations, a time of day and week may be configured that
specifies when the RS device 200 should actively monitor an area.
In some configurations, the sensitively of the object detection in
the RS device 200 may be adjusted. The RS device 200 may be
configured with different vehicle wake up criteria.
[0062] In some configurations, a limit may be specified that
indicates a maximum number of vehicle wakeups that may be issued in
a predetermined amount of time. In some configurations, when the
maximum number of vehicle wakeups is exceeded, the system may issue
a remote start command to the vehicle 10 via transmission of a
remote start signal through the RF communications interface 208. In
some configurations, the remote start command may be issued
automatically when waking the vehicle sensors. Some configurations
may allow remote start of the vehicle 10 only with operator
concurrence. For example, when the vehicle 10 is parked in a garage
the operator may choose not to permit a remote start. Other
configuration commands may include the ability to trigger vehicle
system from the control device for testing purposes.
[0063] FIG. 4 depicts a vehicle application for monitoring
cross-traffic at an intersection or an area where full-view
approach of vehicles or pedestrians is blocked by building,
landscaping, signs, or other obstructions. The vehicle 10 may be a
police car parked near an intersection. A first RS device 500 may
be placed along a street that passes in front of the vehicle 10.
The first RS device 500 may be configured to monitor a first zone
514. The first RS device 500 may have a RF communication
effectiveness within a first range 512. A second RS device 502 may
be placed along the street on an opposite side of the intersection.
The second RS device 502 may be configured to monitor a second zone
510 and may have a RF communication effectiveness within a second
range 508. A third RS device 506 may be placed near the
intersection to act as a repeater to pass RF communication data
between the vehicle 10 and the first RS device 500 and the second
RS device 502. The third RS device 506 may have a RF communication
effectiveness within a third range 516 that includes the vehicle
10, the first RS device 500, and the second RS device 502.
[0064] In some configurations, the first RS device 500, the second
RS device 502, and the third RS device 506 may be permanently
mounted on structures near the intersection. Such a configuration
may allow continued monitoring of the intersection without having
to manually place the RS devices for each usage. For example, the
third RS device 506 may be mounted along with traffic lights or on
a pole supporting traffic lights. The first RS device 500 and the
second RS device 502 may be mounted on light poles within the area.
In this configuration, a source of continuous power may be
available to the RS device modules.
[0065] In some configurations, the operator may be able to
establish communications with the RS device 200 via the
communications module 206. For example, the nomadic device of the
operator may be connected to a wireless network that includes the
RS device 200. The operator may be able to select which boundary
alert sensor(s) to activate and monitor. The operator may send
commands to wake the vehicle 10 via the wireless network. The RS
device 200 may transmit the commands to the vehicle 10 over through
the RF communication module 208. The vehicle 10 may activate
selected boundary alert sensors and transmit the data via the
wireless communications module 56. The data may be received by the
RS device 200 and transmitted to the operator. In some
configuration, the data may be received by the nomadic device of
the operator.
[0066] In some configurations, the vehicle 10 may have autonomous
capabilities. That is, the vehicle may be configured to control
propulsion and steering without driver intervention. The vehicle 10
may be configured to receive a command from the operator to move
the vehicle 10 to a different location. The command may be received
through the RS device 200 or the wireless communication module 56.
The operator may send a new location as a relative position from
the current position of the vehicle 10. In response to receiving
the command, the controller 58 may issue commands to propulsion,
braking and steering components to move the vehicle 10 to the new
position. For example, the view of the cameras may be obstructed in
the current position of the vehicle. The operator may send a
command to reposition the vehicle 10 to avoid obstructing the
cameras or other sensors.
[0067] The capability of the vehicle 10 to interface with RS device
modules 200 opens up many possible applications. Applications for
enhancing vehicle security are possible. Using the vehicle 10 to
monitor and secure an area is also possible.
[0068] The processes, methods, or algorithms disclosed herein can
be deliverable to/implemented by a processing device, controller,
or computer, which can include any existing programmable electronic
control unit or dedicated electronic control unit. Similarly, the
processes, methods, or algorithms can be stored as data and
instructions executable by a controller or computer in many forms
including, but not limited to, information permanently stored on
non-writable storage media such as ROM devices and information
alterably stored on writeable storage media such as floppy disks,
magnetic tapes, CDs, RAM devices, and other magnetic and optical
media. The processes, methods, or algorithms can also be
implemented in a software executable object. Alternatively, the
processes, methods, or algorithms can be embodied in whole or in
part using suitable hardware components, such as Application
Specific Integrated Circuits (ASICs), Field-Programmable Gate
Arrays (FPGAs), state machines, controllers or other hardware
components or devices, or a combination of hardware, software and
firmware components.
[0069] While exemplary embodiments are described above, it is not
intended that these embodiments describe all possible forms
encompassed by the claims. The words used in the specification are
words of description rather than limitation, and it is understood
that various changes can be made without departing from the spirit
and scope of the disclosure. As previously described, the features
of various embodiments can be combined to form further embodiments
of the invention that may not be explicitly described or
illustrated. While various embodiments could have been described as
providing advantages or being preferred over other embodiments or
prior art implementations with respect to one or more desired
characteristics, those of ordinary skill in the art recognize that
one or more features or characteristics can be compromised to
achieve desired overall system attributes, which depend on the
specific application and implementation. These attributes may
include, but are not limited to cost, strength, durability, life
cycle cost, marketability, appearance, packaging, size,
serviceability, weight, manufacturability, ease of assembly, etc.
As such, embodiments described as less desirable than other
embodiments or prior art implementations with respect to one or
more characteristics are not outside the scope of the disclosure
and can be desirable for particular applications.
