Abstract
Abstract A method and apparatus for locating and communicating with vehicles is provided, including at least one mobile cellular unit connected to at least one microprocessor and installed within a vehicle. The microprocessor interrogates the mobile cellular unit to obtain location information from an overhead message stream transmitted from cellular telephone transmitter sites. The location is displayed on a display located in the vehicle or the microprocessor periodically instructs the mobile cellular unit to initiate a call to a host controller and, upon receipt of transmitting instructions from the host controller, transmits the location information for display on a screen connected to the host controller.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
145 words
A system for locating and communicating with a vehicle by a cellular telephone system, said cellular telephone system emitting data containing cellular telephone system information, comprising: a remote host controller coupled to the cellular telephone system having a display for displaying communications and geographic location data transmitted from the vehicle; a cellular transceiver within the vehicle; and a controller in the vehicle connected to said cellular transceiver wherein said controller interprets the data received from said cellular telephone system and determines geographic location data transmitted from the cellular telephone system providing communication services to said cellular transceiver said controller further communicating with said remote host controller and transmitting the geographic location data, said remote host controller receiving and processing the geographic location data for determining an approximate geographic location of the vehicle and for displaying the approximate geographic location of the vehicle on said display.
Claim 2
Independent Claim
145 words
A system for locating and communicating with a vehicle by a cellular telephone system, said cellular telephone system emitting data containing cellular telephone system information, comprising: a remote host controller coupled to the cellular telephone system having a display for displaying communications and geographic location data transmitted from the vehicle; a cellular transceiver within the vehicle; and a controller in the vehicle connected to said cellular transceiver wherein said controller interprets the data received from said cellular telephone system and determines geographic location data transmitted from the cellular telephone system providing communication services to said cellular transceiver said controller further communicating with said remote host controller and transmitting the geographic location data, said remote host controller receiving and processing the geographic location data for determining an approximate geographic location of the vehicle and for displaying the approximate geographic location of the vehicle on said display.
Claim 3
Dependent Claim
35 words
The locating and communicating system of claim 1, wherein said cellular transceiver further comprises a hands-free microphone with voice actuation to enable an operator of the vehicle to input verbal information to said cellular transceiver.
Claim 4
Dependent Claim
31 words
The locating and communicating system of claim 1, wherein said controller further comprises a vehicle status monitor providing information for transmission to said remote host controller for display on the display.
Claim 5
Dependent Claim
40 words
The locating and communicating system of claim 1, wherein said controller further comprises an alarm system that activates said cellular transceiver to establish a communication link with said remote host controller to report unauthorized entry and operation of the vehicle.
Claim 6
Dependent Claim
41 words
The locating and communicating system of claim 1, further comprising a timer connected to said controller to determine predetermined time intervals for interrogating said cellular transceiver and then initiating a communications link between said cellular transceiver and said remote host controller.
Claim 7
Independent Claim
102 words
A method for locating a vehicle equipped with a cellular transceiver using a cellular telephone system, said cellular telephone system including a transmitter emitting data containing cellular telephone system information, comprising the steps of: determining geographic location data from said cellular telephone system information; establishing a communications link between the cellular transceiver and a remote host controller having a display; transmitting to said remote host controller the identity of said vehicle and geographic location data; determining an approximate geographic location of said vehicle by interpreting said geographic location data; and graphically displaying on said display the approximate geographic location of said vehicle.
Claim 8
Independent Claim
102 words
A method for locating a vehicle equipped with a cellular transceiver using a cellular telephone system, said cellular telephone system including a transmitter emitting data containing cellular telephone system information, comprising the steps of: determining geographic location data from said cellular telephone system information; establishing a communications link between the cellular transceiver and a remote host controller having a display; transmitting to said remote host controller the identity of said vehicle and geographic location data; determining an approximate geographic location of said vehicle by interpreting said geographic location data; and graphically displaying on said display the approximate geographic location of said vehicle.
Claim 9
Dependent Claim
47 words
The locating method of claim 6, further comprising the step of measuring the time interval following the transmission of information from said cellular transceiver to said remote host controller and initiating transmission of information from said cellular transceiver upon the expiration of a predetermined period of time.
Claim 10
Dependent Claim
40 words
The locating method of claim 6, further comprising the step of remotely programming authorized access numbers in said cellular transceiver from said remote host controller for inhibiting calls from said cellular transceiver other than calls to said authorized access numbers.
Claim 11
Dependent Claim
34 words
The locating method of claim 6, further comprising the step of interrogating a data base to identify said transmitter providing service to the cellular transceiver to determine said approximate geographic location of said vehicle.
Claim 12
Dependent Claim
106 words
The locating method of claim 6, further comprising steps for locating the vehicle between transmissions including: determining the location of the vehicle at the time of the last transmission; identifying the final destination and anticipated route of the vehicle; calculating the average speed of the vehicle from previous transmissions; determining the approximate geographic location of the vehicle by calculating the distance traveled along the anticipated route using the average speed of the vehicle and the elapsed time since the last transmission from the vehicle; interrogating a data base to obtain system geographic location data and system connection data for the cellular telephone system serving the vehicle.
Claim 13
Dependent Claim
22 words
The locating method of claim 6, wherein the step of transmitting to said remote host controller further comprises transmitting vehicle performance information.
