Description
TECHNICAL FIELD
[0001] The present invention relates to a method and apparatus for
monitoring unauthorized usage of a vehicle and, more particularly,
the present invention relates to a method and apparatus that
detects conditions of a driver and a vehicle that indicate
operation of the vehicle is unauthorized and provide a response to
the detected conditions.
BACKGROUND ART
[0002] Unintended usages of a vehicle, such as a tractor trailer,
include driving under the influence of drugs or alcohol, driving of
a vehicle when fatigued, driving of a stolen vehicle, deviating
from a planned route, driving a vehicle into a restricted area,
uncoupling a trailer at an unplanned location, and driving a
vehicle in need of maintenance.
[0003] Driving of a vehicle by an impaired operator greatly
increases the chance that the vehicle will be involved in an
accident. Federal Motor Carrier Safety Standard #49 C.F.R. 392.3
requires fatigue impaired drivers to stop. According to the
National Highway Traffic Safety Administration (NHTSA), one out of
eight traffic fatalities in 1998 resulted from a collision with a
large truck. Alcohol related fatalities accounted for 38% of all
traffic fatalities in 1998. According to the Commercial Car Journal
(CCJ) survey, 55% of drivers violate hours of service (HOS) rules
by driving more than 10 hours without an 8 hour break. Stolen
tractors and/or trailers cost fleet owners a large sum of money per
occurrence. Vehicles may become unsafe when they are not properly
maintained.
[0004] Prior art disclosures have dealt with monitoring vehicle
drivers. Examples include detecting a drowsy driver by monitoring
eyelid movement of the driver, detecting drowsiness by sensing
meandering of a vehicle in a lane of a road, monitoring heart rate
and skin vibrations to detect the mental condition of the driver,
testing a drivers alertness by requiring the driver to move a turn
signal lever in a sequence of requested directions, detecting
intoxication by monitoring a driver's iris, monitoring acceleration
and deceleration and steering irregularities to determine a drivers
fitness.
[0005] Prior art disclosures have dealt with tampering with a
trailer. It is known in the prior art to sense penetration into a
trailer. A camera and sound recorder is used during theft. One
prior art theft prevention system monitors doors and alerts a
central control.
[0006] It is known in the prior art to track travel of a long haul
truck within an acceptable rectangular zone and report exceptions
to a central control or generate an exception report.
[0007] What is needed is an interactive monitoring system that
detects conditions that indicate unauthorized vehicle usage and
provides for a response to the detected conditions that assures
that the usage is not unauthorized or shuts the vehicle down.
DISCLOSURE OF INVENTION
[0008] The present invention relates to a method and apparatus for
monitoring unauthorized usage of a vehicle. One embodiment of the
method of monitoring unauthorized usage of a vehicle concerns
testing the competency of a driver to operate a motorized vehicle.
A randomly generated number is displayed in the vehicle for a given
period of time. A user interface is provided in the vehicle for the
driver to enter digits that correspond to the randomly generated
number. The system determines whether the driver has entered the
digits that correspond the randomly generated number in a proper
sequence within a given period of time. In the exemplary
embodiment, a vehicle computer is used to generate the randomly
generated number. The user interface is connected to the vehicle
computer. A display is coupled to the computer for displaying the
randomly generated number. The computer is programmed to determine
whether the driver has entered digits that correspond to the
randomly generated number in a proper sequence.
[0009] In one embodiment of the method of testing the competency of
a driver to operate a motorized vehicle, a forward sequence
notation or a reverse sequence notation is displayed. The forward
or reverse sequence notation provides an indication to the driver
to enter the digits in one of a forward sequence or a reverse
sequence. The proper sequence corresponds to the displayed sequence
notation. A driver reaction time may be logged when it is
determined that the driver has entered digits that correspond to
the randomly generated number in the proper sequence within the
given period of time. The driver is retested after a given period
of time. The driver may be required to enter a driver
identification code before the randomly generated number is
displayed. A new driver is tested when the driver enters a driver
identification code. At least one of the driver reaction time and
an ability to enter the digits that correspond to the randomly
generated number are logged when the driver fails to enter digits
that correspond to the randomly generated number in the proper
sequence within the given period of time. A central control is
notified when the driver has failed to enter the digits that
correspond to the randomly generated number in the proper sequence
within a given period of time. The vehicle may be disabled when the
driver fails to enter digits that correspond to the randomly
generated number in the proper sequence within the given period of
time.
[0010] In one embodiment, a vehicle is disabled when a potential
theft occurs. The system determines that a driver is not authorized
to operate the vehicle. The system also determines that the vehicle
has deviated from a planned route. The vehicle is disabled when it
is determined that the driver is not authorized to operate the
vehicle and has deviated from the planned route.
[0011] Variations of the method of disabling a vehicle when a
potential theft occurs include tracking the location of the vehicle
and notifying a central control location when it is determined that
the driver is not authorized to operate the vehicle and it is
determined that the vehicle has deviated from the planned route. In
the method, the driver may be requested to enter an authorized
driver code and route code within a given period of time. The
system will determine whether an authorized driver code has been
entered by the driver. The vehicle will be disabled if an
authorized driver code is not entered by the driver.
[0012] In one embodiment, a vehicle computer and a global
positioning system are used to determine that the driver is not
authorized to operate the vehicle and the vehicle has deviated from
the planned route. The vehicle computer has an interface that
allows the driver to enter a driver authorization code. The
computer is programmed to determine whether the driver is
authorized to operate the vehicle. The global positioning system is
coupled to the computer for determining that the vehicle has
deviated from the planned route. The computer is programmed to
disable the vehicle when the driver is not authorized and the
vehicle has deviated from the planned route.
[0013] In one embodiment, a vehicle is disabled when a
predetermined number of service hours is exceeded. The system
determines whether an allowable number of service hours has been
exceeded by a driver. A central control is notified when the
allowable number of vehicle service hours has been exceeded by the
driver. The system determines whether the central control provided
authorization to exceed the allowable number of service hours. The
driver is notified that the vehicle will be disabled within a given
period of time when authorization to exceed the allowable number of
vehicle service hours is not granted. The vehicle is then
disabled.
[0014] In variations of the method for disabling a vehicle when a
predetermined number of service hours is exceeded includes
reactivating the vehicle by entering a valid drivers code. The
driver code may be. revalidated after a defined rest period has
lapsed.
[0015] In one embodiment, a vehicle computer and a communication
system are used to disable a vehicle when a predetermined number of
service hours is exceeded. The vehicle computer is programmed to
determine whether an allowable number of service hours has been
exceeded by the driver. The communication system is coupled to the
computer for notifying the central control when the allowable
number of service hours has been exceeded. The communication system
is configured to receive authorization from the central control to
exceed the allowable number of service hours and to notify the
driver that the vehicle would be disabled within the given period
of time when authorization to exceed the number of allowable
vehicle service hours is not granted. The computer is programmed to
disable a vehicle when authorization to exceed the allowable number
of vehicle service hours is not granted by the central control.
[0016] In one embodiment, a route traveled by a vehicle is
controlled. An authorized route is defined with an acceptable
deviation radius. When it is determined that a location of the
vehicle is outside the acceptable deviation radius, the vehicle is
shut down. A computer and global positioning system may be used to
control the route traveled by the vehicle. The computer is
programmed to define the authorized route with the authorized
acceptable deviation radius. The global positioning system is
coupled to the computer for determining location of the vehicle.
The computer is programmed to determine whether the location of the
vehicle is outside the acceptable radius. The computer shuts down
the vehicle if the vehicle is outside the acceptable deviation
radius for a predetermined period of time.
[0017] In variations of the method for controlling a route traveled
by the vehicle, the driver and a central controller is notified
that the vehicle has deviated from the authorized route. An
interface between the driver and the central control is provided
that allows the driver to request authorization to deviate from the
authorized route. The system determines whether authorization from
the central control to deviate from the authorized route is
granted. The vehicle is allowed to deviate from the authorized
route when authorization to deviate from the authorized route is
granted by the central control. The vehicle is shut down if the
vehicle fails to enter the acceptable deviation radius or obtain
authorization to deviate from the authorized route from the central
control. Emergency start instructions may be displayed when the
vehicle is shut down. Control information may be displayed that
allows emergency personnel to obtain a valid driver code and
temporary route deviation code.
[0018] In one embodiment, a route traveled by the vehicle is
controlled. A perimeter is defined around a restricted area. When
it is determined that a location of the vehicle is inside the
perimeter around the restricted area, the vehicle is shut down. The
computer and a global positioning system may be used to define the
perimeter around a restricted area and determine whether the
location of the vehicle is inside the perimeter. The computer is
programmed to define a perimeter around the restricted area. The
global positioning system is coupled to the computer for
determining the location of the vehicle. The computer is programmed
to determine whether a location of the vehicle is inside the
perimeter. The computer shuts the vehicle down if the vehicle is
inside the perimeter.
[0019] In variations of the method for controlling a route traveled
by a vehicle the driver, a central controller, and a restricted
area site are notified that the vehicle is in the perimeter around
the restricted area. The system determines whether authorization
from the restricted areas site to enter the perimeter of a
restricted area is granted. The vehicle is allowed to enter the
perimeter of a restricted area when authorization to enter the
perimeter is granted. The vehicle is shut down if the vehicle fails
to leave the perimeter or obtain authorization to enter the
perimeter from the restricted area site. Law enforcement officials
may be notified that the perimeter has been breached. The vehicle
may be reactivated by entering a valid drivers code and the
temporary route deviation code. Emergency start instructions may be
displayed when the vehicle is shut down. Contact information may be
displayed that allows emergency personnel to obtain a valid driver
code and a temporary route deviation code that allows the vehicle
to be moved.
[0020] In one embodiment, uncoupling of a vehicle trailer is
monitored. A planned trailer uncoupling area is defined. When it is
determined that the trailer has been uncoupled outside the planned
uncoupling area, the system determines the location of the vehicle
with a global positioning system. Uncoupling of the vehicle trailer
may be monitored using an onboard vehicle computer and a global
positioning system. The vehicle computer is programmed to define a
planned trailer uncoupling area. The global positioning system is
coupled to the computer for determining the location of the
trailer. The computer is programmed to determine that the trailer
has been uncoupled outside the planned uncoupling area.
[0021] In variations of the method for monitoring a vehicle
trailer, a trailer battery backup is activated. The doors of the
trailer are automatically locked. The fifth wheel of the vehicle is
automatically locked. Spring brakes of the trailer are
automatically applied. The tires may be automatically deflated. The
trailer battery backup, the doors of the trailer, the fifth wheel
of the vehicle, tire inflation and/or deflation and the spring
brakes of the trailer may be controlled by the on board vehicle
computer.
[0022] In one embodiment, a location of the vehicle is monitored
when the main electrical power that is supplied to an onboard
vehicle computer is removed. The system determines a main
electrical power supply is not available to the vehicle onboard
computer. A battery backup is activated to power the vehicle
onboard computer. The system determines the location of the vehicle
using a global positioning system. The location of the vehicle is
transmitted to a central control. An onboard vehicle computer, a
backup battery, a global positioning system and a communication
system may be used to monitor the vehicle location when electrical
power supplied to the onboard vehicle computer is removed. The
onboard vehicle computer is programmed to determine that the main
electrical power supply is not available to the vehicle onboard
computer. The backup battery is coupled to the onboard computer.
The computer is programmed to activate the battery backup when the
main electrical power supply is not available to the computer. The
global positioning system is coupled to the computer for
determining the location of the vehicle. The communication system
is coupled to the computer for transmitting the location of the
vehicle to a central control.
[0023] In one embodiment, vehicle maintenance is scheduled. Vehicle
mileage is compared to a predetermined mileage required for
maintenance. A number of hours a vehicle operation is compared to a
predetermined number. of hours of vehicle operation. An indication
that maintenance is required is provided when the vehicle mileage
exceeds the predetermined mileage or when the number of hours of

BEST MODE FOR CARRYING OUT THE INVENTION
[0038] The following disclosure concerns a system 10 that detects
various conditions of a vehicle 12 and a driver 14 or operator that
indicate that the vehicle is being used in an unauthorized manner
and responding to the detected conditions.
[0039] Referring to FIGS. 1 and 2, the illustrated vehicle 12 is a
tractor trailer 16a, 16b. It should be readily apparent that the
system could be used with any type of vehicle, such as an
automobile. In the illustrated embodiment, the tractor 16a is
equipped with an onboard computer 18, a display 20 coupled to the
onboard computer 18 and a user interface 22 coupled to the onboard
computer 18. The display 20 is located in the vehicle dash in the
exemplary embodiment. The display displays messages from the
onboard computer 18. The display 20 is also used for communication
with central control personnel. In the illustrated embodiment, a
digital camera 19 is coupled to the computer 18. The digital camera
is mounted inside the vehicle and is positioned to take a picture
of the driver 14. The camera is mounted on the vehicle dash or the
driver's side "A" pillar facing the person in the driver's
seat.
[0040] Referring to FIG. 2, a global positioning system antenna 24
and a satellite communications unit 26 are coupled to the computer
18. The computer 18 is used to monitor driver identification, hours
behind the wheel, travel distance, driver reaction time and state
of alertness, global positioning system information, such as
location, time and date, speed, direction and distance traveled,
trailer coupling status, main power supply to the unauthorized
vehicle usage system (UVU) 10 and vehicle maintenance data and
status relative to planned vehicle maintenance and status.
[0041] Referring to FIG. 1, the system 10 monitors driver
identification and driver competency using the user interface 22.
The system 10 communicates with a central control 28 and a
restricted area site 30 and receives information from a global
positioning satellite 32 to detect conditions that indicate that
the vehicle 12 is being used in an unauthorized fashion.
[0042] Referring to FIG. 5, in one embodiment the trailer 16b
includes a separate onboard computer 34, a global positioning
system antenna 36 and a satellite communications unit 38.
[0043] FIG. 3 shows the communication between the on-board
computer, the driver, the tractor & trailer, central control,
and restricted areas. The computer 18 is linked to the satellite
communications unit 26 which allows satellite and transceiver
communication and receipt of disabling commands from the control
center 28 or restricted area 30. The satellite communications unit
26 of the tractor 16a and the satellite communications unit 38 of
the trailer 16b allow two way communication between the tractor 16a
and the trailer 16b. A sensor 40 is included on a trailer door 42
that is monitored by the onboard computer 18 or 34 to determine
whether the trailer door 42 is open or closed. The onboard computer
18 monitors whether the trailer electrical connection 43 is open or
closed. The onboard computer 18 controls inflation and deflation of
tires 44 of the tractor trailer 16a, 16b. The onboard computer 18
monitors engine and vehicle data, driver input data and vehicle
mileage. The onboard computer 18 activates tractor disabling
commands, such as fuel shut-off, ignition disabling and flashing
lights, etc.
[0044] FIG. 6 is a flow chart that lists tests performed by the
system 10 that detect conditions that indicate the vehicle is being
used in an unauthorized manner or by an unauthorized person.
Although FIG. 6 illustrates six tests that are performed by the
illustrated system 10 to detect conditions that indicate
unauthorized vehicle usage, it should be readily apparent to those
skilled in the art that each of the tests listed on FIG. 6 can be
used separately to detect conditions that are indicative of
unauthorized vehicle use. In the illustrated embodiment, the system
10 includes a driver competency test 46 and unauthorized driver and
hours of service check 48, a deviation from planned route check 50,
an unplanned trailer uncoupling routine 52, an unplanned loss of
main electrical power to the unauthorized vehicle use onboard
computer check 54 and a daily reporting and preventative
maintenance scheduling check 56.
[0045] FIG. 7 illustrates the driver competency test 46. In the
illustrated embodiment, the driver is prompted to enter a driver
identification code at 58. A randomly generated number is flashed
on the display 20 at 60. In one embodiment, the randomly generated
number is a four digit number that is flashed on the driver's
display screen 20 for four seconds. In one embodiment, a sequence
notation, such as a forward or reverse sequence notation, is
displayed with the randomly generated number. It should be readily
apparent that the number of digits of the number could be a number
other than four.
[0046] In the illustrated embodiment, a sequence direction notation
is also shown on the display 20. For example, a forward indicator
requires the driver to enter the number as flashed on the display.
A reverse indicator requires that the driver enter the same number,
but by entering the digits of the number in reverse order. For
example, if 4935 were shown on the driver's display 20, along with
a "forward" indicator, the driver would be expected to enter 4935.
If the number 4935 where shown on the driver's display along with
"reverse," the driver would be expected to enter 5394. In the
exemplary embodiment, the number of test digits can be increased at
the option of the vehicle owner. The onboard computer 18 randomly
selects the entry sequence required, "forward" or "reverse" in the
illustrated embodiment. The onboard computer 18 determines whether
the number entered by the driver is the correct number entered in
the proper sequence within a given time at 62. FIG. 7 illustrates
that the given time to enter the number in the proper sequence is
within 8 seconds. However, any times listed on the flow charts are
for illustrative purposes only and any time for entering the number
in the proper sequence can be selected.
[0047] If the number is entered in the proper sequence within the
given period of time, the onboard computer 18 logs the driver
reaction time, date and time of the driver competency check for
each attempt at 64. In the illustrated embodiment, a retest is
delayed for a few hours, a specific time of the day or until a new
driver code is entered 66.
[0048] If the driver failed to enter the displayed number in a
proper sequence within the given period of time, the onboard
computer 18 determines whether the driver had failed the test more
than twice within the given period of time at 68, such as 15
minutes in one embodiment. If the driver failed the test less than
three times, the driver is tested again. If the driver failed the
test more than twice within a given period of time, the driver
reaction time and inability to enter the proper number in the
proper sequence is logged and central control is notified of the
situation at 70. In the illustrated embodiment, the onboard
computer 18 may be programmed to optionally disable the vehicle for
one hour or until either central control provides an override code
or a new driver code is entered.
[0049] In the exemplary embodiment, when the driver fails the test
more than twice within the given period of time, fifteen minutes in
the illustrated embodiment, the system logs and transmit to central
control 28 a real time photo of the driver, the reaction time and
the inability to enter the proper number for each attempt at
70.
[0050] In the exemplary embodiment, the driver competency test 46
is required under the following conditions:
[0051] 1. Initial vehicle start-up;
[0052] 2. After a predetermined period of time within a normally
allowed hours of services. This time may be the function of the
planned route and timing. Generally, the predetermined time would
be after midway through the normal hours of service. However, the
driver could be given the flexibility to perform the retest any
time during the second half of his allowable hours of service,
allowing the driver to perform the test at a more convenient
stopping point for food or fuel.
[0053] 3. Each hour beyond the normally allowed hours of
service.
[0054] In the exemplary embodiment, the driver's reaction time is
kept in a history file. In the illustrated embodiment, the user
interface 22 is used to enter the digits of the displayed number.
In the illustrated embodiment, the user interface is a keyboard.
The user interface may also be a keypad or the stalk of an
electronic communications unit. Such as the stalk disclosed in
provisional patent application Serial No. 60/332,865, entitled
"INTEGRATED VEHICLE COMMUNICATIONS DISPLAY," filed on Nov. 6, 2001,
that is incorporated herein by reference in its entirety. The
random number may include numeric, alphanumeric or alphabetic
symbols. The display 20 may display the words "forward" or
"reverse" or the letters "F" or "R" or arrow signals "" or "" to
indicate that a forward sequence or a reverse sequence is required.
For a higher degree of difficulty, the test display can show
forward minus some value or reverse minus some value or forward or
reverse plus some value. For example, F-1 or R+2.
[0055] The degree of difficulty can be tailored to the load being
carried. General loads would use the first level of the test.
Driver's hauling flammable liquids, hazardous or high value
material would be required to pass the test using the higher or
second level of difficulty. The test measures alertness, the
ability to concentrate and reaction time. The degree of difficulty
of the test can be raised by adding digits.
[0056] Examples of two possible levels of difficulty for the test
follow:
1 Degree of Requested Displayed Proper Difficulty Sequence Request
Response NORMAL F 5894 5894 F - 1 6231 6230 R 7684 4867 F AXZ2 AXZ2
R W5BC CB5W HIGHER R - 2 6527 7254 F + 2 66251 66253 R 546W7

[0057] The computer 18 records the result of the test and gives a
warning when the test is failed, but does not necessarily impede
the ability to start or operate the vehicle. The driver competency
test 46 can be overwridden in case of an emergency. However,
overriding the test will be recorded as an intentional override for
a given driver and will be provided in the driver history for the
fleet manager. Recorded results of the driver competency test 46
can be used to counsel the driver, for real time intervention by
the fleet manager and may pass liability from the fleet to the
driver in case of an accident. The driver competency test 46
assesses driver fatigue and substance abuse.
[0058] In one embodiment, if the driver fails the test and ignition
is restricted based upon the failure of the driver competency test
46, an emergency override button can be depressed by the driver for
overriding the first negative evaluation and for starting the
engine during emergency conditions. However, the override action
would be noted for the specific driver, along with the date, time
and odometer reading of the tractor 16a. The fleet manager may
restrict the driving time or distance for an emergency override.
This would allow emergency movement of the vehicle, but would
require a satisfactory test to continue beyond a certain time or
distance.
[0059] The specific reaction time can be preset or left up to the
fleet manager's judgement. The fleet manager can set the system to
require a retest randomly or at set intervals like every six to
twelve hours. If the driver sees a request for retest on the
display 20, the driver should pull over within a set period of time
to perform the test only after the vehicle is safely parked. The
driver competency test 46 gives the driver a warning if reaction
times are not acceptable and that the driver should consider
pulling off the road until the driver is able to exhibit proper
reaction times. Acceptable reaction times for the test can be
reduced as the driver gains experience.
[0060] When a driver uses the emergency override feature, ignores
the computer request for retest or continues to drive with known
poor reaction time, a signal is sent via satellite or cell phone to
the fleet manager giving real time notification of a potentially
impaired driver operating the vehicle and its location in the
exemplary embodiment. The driver competency test 46 can
automatically, or upon the demand of the fleet manager disable the
cruise control feature of the tractor 16a.
[0061] FIG. 8 is a schematic showing the unauthorized driver and
hours of service check 48. The unauthorized driver and hours of
service check 48 detects violations of federal hours of service
requirements, unauthorized usage and route deviation and has the
ability to locate a stolen vehicle. The driver is prompted to enter
an authorized driver code and route code 72. In the exemplary
embodiment, the vehicle 12 does not run longer than a predetermined
amount of time, such as five minutes, if an authorized driver code
and route code are not entered. In the exemplary embodiment, a one
time grace period is available for emergency purposes to move the
vehicle away from a hazardous condition, like sitting on railroad
tracks. The vehicle owner can vary the times shown on FIG. 8.
[0062] The onboard computer 18 determines whether the driver is
authorized 74. If the driver is not authorized, the onboard
computer 18 determines whether the tractor trailer 16a, 16b has
deviated from the authorized route 76. The onboard computer 18
determines that the tractor trailer 16a, 16b has deviated from the
authorized route by comparing the position of the tractor trailer
16a, 16b provided to the onboard computer 18 by the global
positioning system 24 to the route programmed into the onboard
computer 18 as a result of entering a route code. The combination
of an unauthorized driver and deviation from the authorized route
provides an indication that the tractor trailer 16a, 16b has been
stolen or highjacked. The driver is notified to pull over as the
vehicle will be disabled within a given period of time, within five
minutes in the illustrated embodiment and the controller 28 is
notified at 78.
[0063] Vehicle shut down begins after the given period of time has
elapsed at 80. Central control is notified of the vehicle's
location. The vehicle can be reactivated by entering a valid driver
code.
[0064] When the onboard computer 18 determines that the driver is
not authorized, but the tractor trailer 16a, 16b has not deviated
from the authorized route, the system 10 asks the driver to enter
an authorized driver code or voluntarily shut down the vehicle
within a given period of time 82. The central control 28 is
notified that the driver is not authorized by a message that it
sent from the vehicle 12 through the satellite communications unit
26 in the exemplary embodiment. After the given period of time, ten
minutes in one embodiment, has elapsed, the onboard computer 18
determines whether an authorized driver code was entered at 84. If
the computer 18 determines that an authorized driver code was not
entered the driver is notified to pull over as the vehicle will be
disabled with a given period of time 78, five minutes in the
illustrated embodiment. The central control 28 is notified that the
driver is not authorized and in the illustrated embodiment a photo
of the driver is transmitted to central control. Vehicle shut down
begins after the predetermined time. Central control 28 is notified
of the vehicle location. The vehicle will be reactivated by
entering a valid driver code 80.
[0065] When the computer 18 determines that the driver is
authorized at 74 or that an authorized driver code was entered at
84 the computer 18 determines whether a maximum allowable number of
hours has been exceeded 86. If the maximum number of allowable
hours has not been exceeded, the unauthorized driver and hours of
service check is repeated after a given period of time, one hour in
the illustrated embodiment. If the predetermined maximum number of
hours allowed is exceeded, the driver is notified to pull off the
road for a rest period as hours have been exceeded 88. The computer
18 determines whether the driver shut down the vehicle within a
predefined time, thirty minutes in one embodiment or whether a new
driver took over 90. The computer determines whether the vehicle
shut down by monitoring the vehicle. The computer determines
whether a new driver took over by determining whether a new driver
code was entered.
[0066] If the vehicle was shut down within a predefined time,
thirty minutes in the illustrated embodiment, or a new driver took
over, the unauthorized driver and hours of service check 48 is
periodically repeated every one hour in the illustrated
embodiment.
[0067] If the driver did not shut the vehicle down within thirty
minutes and a new driver did not take over, the onboard computer 18
causes the satellite communications unit 26 to notify central
control that the driver has exceeded the maximum number of
allowable hours 92. In the exemplary embodiment, central control 28
may give the driver authorization to exceed allowable hours by one
hour. The onboard computer 18 monitors the satellite communications
unit 26 to determine whether central control gave the driver a
revised authorization code to exceed allowable hours. The onboard
computer 18 determines whether central control issued and the
driver entered the revised authorization code to exceed the
allowable hours by one hour at or a new driver took over at 94. If
central control gave the driver an authorization code that was
entered by the driver to exceed allowable hours by one hour, the
unauthorized driver and hours of service check is performed again
at a predefined time, one hour in the illustrated embodiment. If
central control did not give a revised authorization code to exceed
allowable hours or the driver did not enter the revised
authorization code to exceed allowable hours by one hour, the
driver is notified to pull over as the vehicle will be disabled
after a predefined time has elapsed at 96, thirty minutes in one
embodiment. Vehicle shut down begins after the predefined time,
thirty minutes in the exemplary embodiment has lapse 98. Central
control 28 is notified of the vehicle's location. The vehicle can
be reactivated by entering a valid driver code. The prior drivers
code will be valid again after the defined rest period has lapsed.
In the illustrated embodiment, the system 10 notifies central
control and logs and transmits a real time photo of the driver when
the unauthorized driver and hours of service check 48 determines
that the driver is not authorized.
[0068] Allowable hours of service can be entered into the onboard
computer 18 that can keep track of each identified authorized
driver to track the number of hours the driver operates the
vehicle. Using an internal clock or time obtained from a global
positioning system the onboard computer 18 can also determine when
enough time has elapsed to consider the driver to have had enough
time to rest and resume driving.
[0069] The vehicle owner can predetermine the degree to which the
vehicle is disabled or shut down. The disabling or shut down can
include activation of a fifth wheel or trailer door locks.
[0070] Vehicle operation without proper driver identification is
considered to be unauthorized use of a vehicle. Prolonged use of
the vehicle by an apparently known driver who fails to take or pass
the competency test 46 results in a message being sent via cell
phone, radio or satellite transmission to the fleet manager. Global
positioning system data will be sent to the fleet manager alerting
the fleet manager of the vehicle's location. In the illustrated
embodiment, manual entry of the driver identification is employed
since keys and bar codes could be inadvertently left in the
vehicle. Manual entry of the driver identification number may also
form part of the driver competency test 46.
[0071] After a limited number of attempts are made to enter the
driver identification number the system will lock down and notify
the fleet manager of the vehicle's location.
[0072] An active intervention option is available to the fleet
manager to restrict vehicle performance remotely, to encourage the
unauthorized driver to pull off the road, or the fleet manager
could pass along the vehicle description and its location to law
enforcement personnel
[0073] FIG. 9 is a flow chart that illustrates the deviation from a
planned route check 50. The global positioning system 24 tracks the
location of the vehicle 12 and provides the location of the vehicle
12 to the onboard computer 18. The onboard computer 18 determines
whether the vehicle has deviated from the authorized route in
excess of a predetermined limit at 110. If the onboard computer 18
determines that the vehicle has not deviated from the authorized
route, a predetermined amount of time, five minutes in the
illustrated embodiment, is allowed to elapse and the check 50 is
performed again.
[0074] If the vehicle onboard computer 18 determines that the
vehicle has deviated from the authorized route in excess of company
limits, the driver is notified to return to the planned route,
contact central control for route deviation authorization or
prepare to shut down the vehicle at 112. In one embodiment, the
driver is notified that the vehicle will be shutdown in 15 minutes.
The system 10 contacts central control 28 to notify central control
28 that the tractor trailer 16a, 16b has deviated from the
authorized route.
[0075] The onboard computer 18 then checks to determine whether the
vehicle has entered a restricted perimeter or is approaching a
restricted perimeter at 114. In the illustrated embodiment, the
vehicle onboard computer 18 determines that the vehicle 12 is in a
restricted perimeter when the distance between the vehicle global
positioning system location and the restricted perimeter global
positioning system location is less than a predetermined distance
X.
[0076] If the onboard computer 18 determines that the vehicle has
not entered a restricted perimeter or is not approaching a
restricted perimeter, the onboard computer 18 determines whether
the vehicle has returned to the planned route or obtained a route
deviation authorization code within a predetermined time at 116. In
one embodiment, the predetermined time is approximately 15 minutes.
If the vehicle has returned to the planned route or obtained a
route deviation authorization code within the predetermined amount
of time, the deviation from planned route check 50 is repeated
after a given period of time elapses.
[0077] If the onboard computer 18 determines that the vehicle has
not returned to the planned route or obtained a route deviation
authorization code within a predetermined amount of time, the
driver is notified that failure to enter a deviation authorization
code within a predetermined amount of time, five minutes in one
embodiment, will result in vehicle shut down at 118. The system 10
notifies central control of the vehicle location and impending shut
down. The system 10 logs and transmits a real time photo of the
driver in the illustrated embodiment.
[0078] Vehicle shut down begins after the predetermined amount of
time lapses at 120. The vehicle can be reactivated by entering a
valid driver code and temporary route deviation code. The display
20 shows a note on the driver's screen with emergency instructions,
a contact phone number for use by emergency. or law enforcement
personnel to obtain temporary authorization driver codes and route
deviation codes at 122.
[0079] If the onboard computer 18 determines that the vehicle has
entered a restricted perimeter at 114 the driver is notified that
an unauthorized perimeter has been breached and the vehicle will be
disabled within a given period of time, five minutes in the
illustrated embodiment, if a proper authorization code is not
entered 124. The system instructs the driver to pull off the road
or redirect the vehicle. The system notifies central control 28 of
the vehicle location and informs central control 28 that a breach
of a restricted area occurred. The system 10 logs and transmits a
real time photo of the driver.
[0080] The onboard computer 18 monitors information from the global
positioning system antenna 24 to determine the position of the
vehicle 12. The onboard computer 18 determines whether a route
deviation authorization code is entered within the given period of
time, five minutes in one embodiment, or the vehicle has left the
restricted perimeter at 126. If the onboard computer 18 determines
that a route deviation authorization code is entered within the
predetermined time or the vehicle has left the restricted area, the
onboard computer 18 determines whether the vehicle has returned to
the planned route or entered a route deviation authorization code
at 116.
[0081] If the onboard computer 18 determines that a route deviation
authorization code was not entered within the prescribed period of
time, or the vehicle has not left the restricted perimeter, the
system 10 begins vehicle shut down 128. In one embodiment, vehicle
shut down begins immediately. The system 10 notifies central
control and law enforcement officials 9 of the vehicle location and
that the restricted area has been breached. The vehicle 12 can be
reactivated by entering a valid driver code and temporary route
deviation code. The system 10 shows a note on the driver's screen
with emergency instructions, a contact phone number for use by
emergency or law enforcement personnel to obtain temporary
authorized driver code and route deviation code 122.
[0082] In the exemplary embodiment, authorized vehicle routes are
defined by a central control similar to an aircraft flight plan and
given a route code number for entry into the onboard computer 18.
The driver may deviate from the authorized route within a defined
tolerance radius established by central control or if the driver is
given a temporary override code by central control. The onboard
computer 18 compares the vehicle's global positioning system
location to the authorized route to determine compliance.
[0083] Restricted areas are considered to be sensitive and should
not be entered without specific authorization by the site itself.
Examples of possible restricted sites are as follows:
[0084] 1. Nuclear facilities
[0085] 2. Military posts and/or National Guard Armories
[0086] 3. Water supplies
[0087] 4. Oil refineries
[0088] 5. Suspension bridges
[0089] 6. Tunnels
[0090] Specific global positioning system locations for each site
entered into the computer may be offset slightly to avoid providing
specific sensitive information about the site. The perimeter around
each site can be given a unique radius by the system 10.
[0091] In one embodiment, the onboard computer 18 sends a radio
message to the restricted site notifying the restricted site of the
approaching vehicle and the vehicle's identification. The
restricted site may then send a warning that the vehicle is not
authorized. If an unauthorized vehicle continues to approach the
restricted site after the warning is given, the restricted site
controller could then send a second radio signal to disable the
vehicle. In one embodiment, the default code could be to disable
the vehicle unless the restricted site sends a positive
authorization directed to a specific vehicle.
[0092] FIG. 10 is a flow chart that illustrates the unplanned
trailer uncoupling check 52. In the exemplary embodiment, the
onboard computer 18 monitors an-electrical cable 130 that supplies
power to the trailer 16b. In the exemplary embodiment the onboard
computer 18 is programmed to define a planned trailer uncoupling
location. The onboard computer 18 determines whether the trailer
electrical cable has been disconnected at a location outside the
planned uncoupling location at 132. In the exemplary embodiment,
the planned trailer uncoupling location includes a predefined
radius around the selected location.
[0093] If the onboard computer 18 determines that the trailer
electrical cable has not been disconnected at a location outside
the planned global positioning system radius for trailer
uncoupling, the routine ends and may be repeated periodically.
[0094] If the onboard computer 18 determines that the trailer
electrical cable has been disconnected at a location outside the
planned trailer uncoupling radius, the satellite communications
unit 26 of the system 10 transmits the vehicle location and fault
condition to central control 28 at 134. The system 10 notifies the
driver that the trailer cable should be reconnected and/or an
override code should be entered. An optional trailer battery backup
is activated and the satellite communications unit 38 of the
trailer 16b transmits the trailer. 16b identification and location
to the central control 28 if the location is different than the
location of the tractor 16a. In one embodiment, the onboard
computer 18 of the trailer 16b activates optional trailer door
locks, a fifth wheel 87 lock, deflates vehicle tires 89 and/or
applies trailer spring brakes. In an alternate embodiment, the
onboard computer 18 remotely applies trailer door locks and/or
applies trailer spring brakes.
[0095] In the illustrated embodiment, the system 10 retransmits the
tractor 16a and/or trailer 16b location to central control 28 each
time a predetermined amount of time elapses, only if the location
of the tractor 16a and/or trailer 16b changes. In the illustrated
embodiment, the camera 19 takes a picture of the driver and
transmits it real time if the vehicle is moving at 135. The onboard
computer 18 continues to monitor the electrical cable 130 that
powers the trailer 16b. The onboard computer 18 determines whether
the trailer cable has been reconnected and an override code entered
or the trailer 16b has been moved to an authorized uncoupling
location at 136. If the trailer cable has been reconnected and an
override code has been entered, or the trailer 16b has been moved
to an authorized uncoupling location, the routine ends or may be
repeated after a predetermined amount of time. If the trailer cable
has. not been reconnected, an override code has not been entered
and the trailer has not been moved to an authorized uncoupling
location as detected by the global positioning system, the system
10 retransmits the vehicle and/or trailer location if the location
has changed at 135.
[0096] The system on the trailer 16b is similar to the system on
the tractor 16a. Improper disconnection of the electrical cable 130
activates the system on the trailer 16b.
[0097] FIG. 11 is a flow chart that illustrates the unplanned loss
of power check 54 to the system onboard computer 18. The system 10
is equipped with a battery backup 100 in the illustrated embodiment
for limited satellite communications of global positioning system
location in case the main power is shut off prior to entry of
properly authorized maintenance codes. A minimum number of daily
transmissions of data would be expected. Failure of the system to
communicate with the central location may provide an indication of
vehicle tampering. An unplanned loss of main electrical power to
the system onboard computer indicates possible tampering. The
system onboard computer is powered by the vehicle's main power
supply 138. The battery backup powers the onboard computer 18 when
the main electrical power supply becomes unavailable to the onboard
computer 18. The onboard computer 18 determines whether the main
electrical power supply is available to the onboard computer 140.
If the onboard computer 18 determines that the main electrical
power supply is available to the computer 18, the unplanned loss of
power routine ends and may be repeated at given time intervals. If
the onboard computer 18 determines the main electrical power supply
is not available to the onboard computer 18 the battery backup is
activated at 142. The onboard computer 18 causes the satellite
communications unit 26 to transmit the global positioning system
location, the vehicle identification number and fault condition to
central control 28. The system 10 also requires that the driver
enters a proper. disarming code or reestablishes main electrical
power to the onboard computer 18 within a predetermined period of
time, fifteen minutes in the illustrated embodiment, or the
vehicle. may be further disabled.
[0098] The onboard computer 18 determines whether the main
electrical power has been reestablished or proper disarming codes
are entered within the given time period at 144. If the main
electrical power is reestablished within the given time or proper
disarming codes are entered, the unplanned loss of power routine 54
ends and may start again after a predetermined amount of time
elapses. If the electrical power is not reestablished and disarming
codes are not entered within the given period of time, the system
10 transmits the global positioning system location, vehicle
identification number, real time photo of the driver and fault
condition to central control 28 if the vehicle location changes at
145. In the exemplary embodiment, this information is transmitted
each time a predetermined amount of time elapses, fifteen minutes
in one embodiment, until the vehicle stops moving.
[0099] In one embodiment, the vehicle owner may program a disable
feature that disables the vehicle if the power to the onboard
computer 18 is removed. When the disabling feature is programmed,
the vehicle 12 will be disabled at this point. The system 10 can be
reset by reestablishing the system power or overridden by entering
a disarming code.
[0100] FIG. 12 is a flow chart that illustrates the daily reporting
and maintenance check 56. In the illustrated embodiment, the
onboard computer 18 compares vehicle mileage from that required for
maintenance, identifies planned preventative maintenance
requirements and identifies maintenance that fault codes indicate
is required 148. The onboard computer 18 determines whether there
are any fault codes or there is any planned maintenance that is
required 149. If the onboard computer 18 determines that there are
no fault codes and no planned maintenance is required, the system
10 transmits vehicle fault and diagnostic codes, mileage, location,
driver logged hours of service information, compliance to route and
speed limits and the drivers decision regarding scheduling of
maintenance required at 150. The daily report/maintenance check 56
waits twenty-four hours or for a specific time of day to transmit
this information 152. The daily reporting and preventative
maintenance scheduling routine is repeated periodically.
[0101] If the onboard computer 18 determines that there are fault
codes or planned maintenance is required, the system 10 causes the
display 20 to indicate that maintenance is required and/or there
are fault codes 154. The onboard computer 18 uses the global
positioning system location of the vehicle relative to the nearest
authorized maintenance site and provides the driver the option to
view directions to the maintenance site and the area in proximity
with the maintenance site.
[0102] The system 10 then asks the driver if the driver wishes to
schedule repairs or maintenance per the onboard computer
recommendation at 156. If the driver answers "no" the system 10
transmits vehicle fault and diagnostic codes, mileage, location,
driver log hours of service information, compliance to route and
speed limits, and the driver's decision regarding scheduling of
maintenance at 150. If the driver decides to schedule repairs or
maintenance per the onboard computer recommendation, the onboard
computer 18 will request confirmation of scheduled maintenance at
the selected maintenance facility at 158. The onboard computer 18
notifies the driver whether or not maintenance has been scheduled.
The authorized maintenance site will update the maintenance status
of the computer 18 after the work has been completed. The vehicle
fault and diagnostic codes, mileage, location, driver log hours of
service information, compliance to route and speed limits and the
driver's decision regarding scheduling of maintenance is
transmitted to central control at 150.
[0103] The daily reporting and maintenance check allows the central
control 28 to monitor the vehicle's maintenance status and the
driver's decision regarding required maintenance.
[0104] In the exemplary embodiment, the extent to which the vehicle
is "shut down" is controlled by the vehicle owner, within limits.
The owner may disable or reduce any of the computer controlled
functionality of the vehicle to safely inhibit further unauthorized
usage of the vehicle. For example, the vehicle owner may reduce the
available fuel flow of the vehicle to limit the speed of the
vehicle or limit the load a vehicle can handle. A more drastic
measure would be to completely shut off the fuel flow or deflate
one or more of the vehicle's tires.
[0105] The following table provides examples of some of the
conditions detected by the unauthorized usage system 10 and
responses that may be provided by the system. Information that can
be logged with the system using the driver identification includes
GPS information, vehicle speed and engine running time. The system
can give an alert to the driver or fleet manager when a given
driver is approaching or exceeding the safe amount of time on the
road without proper rest. Non driving time can be separated by the
system using zero speeds or fixed global positioning system
positions as defining factors. The system 10 detects driver
identification or lack thereof, reaction time or alertness test
results, odometer reading and vehicle speed, real time clock and
data information, date and time of the usage of the emergency
override feature and time and distance driven in the emergency
override mode, failure to pull over for retest, including mileage
and time beyond reasonable request, global positioning system data
for vehicle location and vehicle identification number and
description. The driver may be identified by a bar code, a smart
key or manual entry of the driver identification number.
