`ABSTRACT
`[57]
`The present invention provides a vehicle tracking and
`security system which allows immediate response in
`case of vehicle theft, an accident, vehicle breakdown, or
`other emergency. Guardian and tracking functions are
`provided through Mobile Units installed in hidden loca-
`tions in vehicles to be monitored. The Mobile Units
`communicate with a Control Center. Preferably, the
`Mobile Unit provides vehicle theft and intrusion protec-
`tion using an in-vehicle alarm and security system
`linked to the Control Center by a transceiver in the
`Mobile Unit. Also, a keypad or other human interface
`device is provided, allowing a vehicle driver or occu-
`pant to signal the Control Center that a particular type
`of assistance is needed. The vehicle’s location may be
`automatically transmitted to the Control Center along
`with any automatic alarm signal or manually entered
`request, the location being precisely determinable any-
`wherein the world through use of Global Positioning
`System (GPS) information. The present invention pro-
`vides continuous monitoring of a large numberof vehi-
`cles for a broad range of status and emergency condi-
`tions over a virtually unlimited geographic area, also
`allowing manual communication of requests for assist-
`ance to that specific location. Advantageously, the sys-
`tem is implemented using existing commercial or police
`communications equipment.

`SUMMARYOF THE INVENTION
`an experienced auto thief can break into almost any
`vehicle in aslittle as six seconds, regardless of whether
`or not it has an alarm system. On average, fewer than
`one in five of the vehicles stolen in the United Statesis
`recovered and the thief prosecuted. Clearly, known
`alarm systems do not stop determined, experienced
`motor vehicle thieves.
`Various anti-theft devices are known in the art. The
`simplest devices take the form of physical restraints,
`such as doorlocks, steering wheel bars, or wheel locks.
`More sophisticated systems involve passive alarms that
`activate automatically when the driver leaves the car.
`Morerecently, electronic homing devices have been
`developed that can track a vehicle, but only after it is
`reported stolen. After the vehicle is discovered to be
`stolen and reported to police, the police are able to
`track and capturethethief, provided the vehicle owner
`and the police have both invested in special communi-
`cations devices. In addition to being useful only after
`the vehicle is reported stolen, these systems are useful
`only in the geographical areas where the corresponding
`police receivers are located. Moreover, these systems
`are in some cases prohibitively expensive.
`Therefore, there is a need in the art to provide a
`cost-effective automatic vehicle theft detection device
`which immediately alerts the police to the theft, allow-
`ing them to track the vehicle over a wide geographic
`area.
`
`The present invention provides a vehicle tracking
`and security system which provides round-the-clock
`vehicle security, allowing immediate response in case of
`vehicle theft, an accident, vehicle breakdown, or other
`emergency.
`Guardian and tracking functions are provided
`through Mobile Units which are preferably installed in
`hidden locations in vehicles to be monitored. The Mo-
`bile Units communicate with a Control Center in at
`least one-way, and preferably two-way, communica-
`tion. Preferably, the Mobile Unit provides vehicle theft
`and intrusion protection using a in-vehicle alarm and
`security system linked to the Control Center by a trans-
`ceiver in the Mobile Unit. Also, a keypad or other
`human interface device is provided in the vehicle, al-
`lowing a vehicle driver or occupant to signal the Con-
`trol Centerthat a particular type of assistance is needed.
`The vehicle’s location may be automatically transmitted
`to the Control] Center along with any automatic or
`manual request, the location being precisely determin-
`able anywherein the world. In this manner, the present
`invention provides continuous monitoring of a large
`numberof vehicles for a broad rangeof status and emer-
`gency conditions overa virtually unlimited geographic
`area, also allowing manual communication of requests
`for assistance to that specific location. Advantageously,
`the system is implemented using existing Jocation-detec-
`On a related matter, breakdowns, accidents, and med-
`tion systems and conventional commercial or police

`Clearly, it is desirable to be able to quickly and conve-
`According toafirst aspect of the invention, there is

`it is desirable to

`is needed. The presenceofcitizens band radios or cellu-
`tion. The mobile unitalso has a satellite receiver (prefer-
`lar telephones has increased, but these systems suffer

`
`In describing preferred embodiments of the present
`invention illustrated in the drawings, specific terminol-
`ogy is employed for the sake of clarity. However, the
`invention is not intended to be limited to the specific
`terminology so selected, and it is to be understood that
`each specific element includes all technical equivalents
`which operate in a similar manner to accomplisha simi-
`lar purpose.
`the invention is a multi-featured
`Stated generally,
`electronic tracking and security system which includes
`devices that calculate a vehicle’s position, detect local
`events, and calculate a system response based on
`weighted variables. Based on the calculated response,
`the system notifies the vehicle occupants. In certain
`circumstances, the system notifies a Control] Center via
`a preferably two-way communication channel,to allow
`the Control Center to respond appropriately such as by .
`summoning emergency vehicles or remotely control-
`ling the vehicle in some way. Provision of a two-way
`communication system allows the Control Center to
`positively verify the message which was sent by the
`vehicle.
`The preferred embodiment of the present invention
`provides computerized graphic maps which display
`vehicle locations using information ultimately derived
`from the existing Global Positioning System (GPS),
`thereby providing a highly accurate, real-time vehicle
`tracking system. The preferred system provides an inte-
`grated location system, communication network, map-
`ping system, and dispatch capability. The system is
`especially suitable for use in fleet vehicle management,
`vehicle theft deterrent, stolen vehicle tracking, railroad
`car tracking, cargo location, and so forth. The system
`may be customized toa particular user’s needs and, due
`to the preferred embodiment’s use of the GPS, may be
`installed and used virtually anywhere in the world.
`Referring to FIG. 1, the invention involves a set of
`“Mobile Units” 100A-100E which are provided on
`respective vehicles 102A-102E that are to be moni-
`tored, protected, or tracked. A communications link
`110 is provided between the Mobile Units (hereinafter
`collectively indicated 100) and a “Control Center” 150
`which is manned by one or more trained operators 152.
`The Mobile Unit may automatically detect certain sta-
`tus and alarm conditions, or a driver or passengerin the
`vehicle may manually request certain assistance, both of
`which actions may be immediately communicated to
`the Control Center along with automatically generated
`GPS-derived positioning data. The Control Center
`operator may take action as appropriate, including dis-
`patching of emergency vehicles 160, 162, 164, 166, 168,

`commanding the appropriate Mobile Unit 100 to repeat-
`edly transmit position data, or ignoring the Mobile
`Unit’s communication. Certain functions may be either
`automated or manually controlled by the Control Cen-
`ter operator, such as whether the vehicle horn is
`sounded in response to an unexpected motion sensor
`activation indicating theft of the vehicle.
`In particular, the vehicles may include a conventional
`passenger automobile 102A, a setoffleet vehicles 102B,
`102C, 102D (such as buses or other mass transit vehi-
`cles, courier vehicles, delivery vehicles, utility vehicles,
`sanitation trucks, armored cars, police cars, rental cars,
`and so forth), as well as a train 102E. The communica-
`tions link 110 is preferably implemented as a conven-
`tional cellular telephone link, but of course need not be
`so limited. The Control Center 150 may appropriately
`summonhelp in the form ofpolice 160, a fire truck 162,
`an ambulance 164, a wrecker 166, or other appropriate
`help, generally indicated as element 168. Each Mobile
`Unit 100 preferably includes means for determining the
`present location of the vehicle 102 in which it is in-
`stalled. Preferably, this means for determining the loca-
`tion is a Global Positioning System (GPS)receiver, not
`only for its accuracy but because the location informa-
`tion transmitted from GPSsatellites is provided free of
`cost.
`
`As readily appreciated by those skilled in the art, the
`GPS was developed by the U.S. Department of Defense
`and placed into service in the 1980’s. The GPS includes
`a constellation of radio-navigation satellites which con-
`stantly transmit precise timing and location information
`to substantially the entire surface of the earth. The GPS
`receiver in the Mobile Unit is preferably implemented
`using a multi-channel GPS receiver so as to acquire
`many (for example, five) transmissions from a corre-
`sponding plurality of GPS satellites simultaneously.
`This allows the Mobile Unit to determine the location
`of the vehicle (within appro
