Abstract

A vehicle speed control system includes an RFID equipped vehicle having a computer system for controlling operating functions of the vehicle, a transmitting and receiving station positioned adjacent a speed control zone, capability for sending a speed control command from the transmitting and receiving station to the vehicle, cooperative components associated with the vehicle for receiving the speed control command from the transmitting and receiving station, and various elements associated with the vehicle for adjusting speed of the vehicle in response to the speed control command received from the station. The transmitting and receiving station includes electronic circuitry and related components for determining the speed of the RFID equipped vehicle as the vehicle enters the speed control zone.

means associated with said vehicle for receiving said speed control command from said transmitting and receiving station; and

means associated with said vehicle for adjusting speed of said vehicle in response to said speed control command received from said station.

4. The vehicle speed control system according to claim 1 wherein said means for determining speed of said RFID equipped vehicle includes a computer operatively associated with said transmitting and receiving station.

5. The vehicle speed control system according to claim 1 wherein said means for sending a speed control command from said transmitting and receiving station to said vehicle includes a radio system.

6. The vehicle speed control system according to claim 1 wherein said means associated with said vehicle for receiving said speed control command from said transmitting and receiving station includes a receiver circuit operatively associated with said computer system of said vehicle.

7. The vehicle speed control system according to claim 1 wherein said means associated with said vehicle for adjusting speed of said vehicle in response to said speed control command received from said transmitting and receiving station includes fuel flow adjustment.

8. The vehicle speed control system according to claim 1 wherein said means associated with said vehicle for adjusting speed of said vehicle in response to said speed control command received from said transmitting and receiving station includes vacuum diaphragm adjustment.

2. A vehicle authentication and immobilizer control system, comprising:

an RFID equipped vehicle including a computer system for controlling operating functions of said vehicle, said vehicle having a vehicle identification number;

a transmitting and receiving station positioned adjacent an entry zone, said transmitting and receiving station including a database of authorized vehicle identification numbers;

means associated with said vehicle for sending its vehicle identification number to said transmitting and receiving station as said vehicle approaches said entry zone;

means associated with said transmitting and receiving station to determine whether said vehicle identification number received from said vehicle is an authorized vehicle identification number; and

means for sending a disable commend from said station to said vehicle when said vehicle identification number received from said vehicle is determined to be unauthorized so that said computer system for controlling operating functions of said vehicle is thereby activated to prevent continued operation for said approaching vehicle.

9. The vehicle authentication and immobilizer control system according to claim 2 wherein said means associated with said vehicle for sending its vehicle identification number to said transmitting and receiving station includes an RFID transmitter.

10. The vehicle authentication and immobilizer control system according to claim 2 wherein said means associated with said transmitting and receiving station to determine whether said vehicle identification number received from said vehicle is an authorized vehicle identification number includes a computer associated with said database.

11. The vehicle authentication and immobilizer control system according to claim 2 wherein said means for sending a disable commend from said station to said vehicle includes a radio system.

3. A method for controlling the speed of a vehicle within a speed control zone, said method comprising the steps of:

providing a vehicle having a computer system for controlling operating functions of said vehicle including speed of said vehicle with an RFID system operatively associated with said computer system;

providing a transmitting and receiving station positioned adjacent said speed control zone, said transmitting and receiving station including means for determining speed of said vehicle as said vehicle enters said speed control zone;

sending a speed control command from said transmitting and receiving station to said vehicle as said vehicle enters proximity of said speed control zone;

receiving said speed control command from said transmitting and receiving station within said computer system of said vehicle; and

adjusting speed of said vehicle in response to said speed control command received from said station.

12. A vehicle speed control system, comprising:

an RFID equipped vehicle having a computer system for controlling operating functions of said vehicle including speed of said vehicle;

a transmitting and receiving station positioned adjacent a speed control zone, said transmitting and receiving station including a computer implemented therein for determining speed of said RFID equipped vehicle as said vehicle enters said speed control zone;

a radio system for sending a speed control command from said transmitting and receiving station to said vehicle;

a receiver circuit operatively associated with said computer system of said vehicle, said receiver circuit enabled to receive said speed control command from said transmitting and receiving station; and

an RFID reader enabled to receive said speed control command received from said station, said RFID reader operatively associated with said computer system of said vehicle to adjust speed of said vehicle in response to said received speed control command.

13. The vehicle speed control system according to claim 12 wherein said vehicle includes a fuel injector and adjustment of said speed of said vehicle in response to said received speed control command is achieved by reducing fuel flow supplied to said fuel injector.

14. The vehicle speed control system according to claim 13 wherein said vehicle further includes a speed sensor operatively associated with said RFID reader and with said computer system of said vehicle, said speed sensor providing desired feed back information to the vehicle computer so that when said received speed control command is processed, speed reduction is achieved in a predictable manner by controlled fuel flow reduction.

15. The vehicle speed control system according to claim 12 wherein said vehicle includes a vacuum control diaphragm and adjustment of said speed of said vehicle in response to said received speed control command is achieved by controlling an amount of vacuum applied to said vacuum control diaphragm.

16. The vehicle speed control system according to claim 15 wherein said vehicle further includes a speed sensor operatively associated with said RFID reader and with said computer system of said vehicle, said speed sensor providing desired feed back information to the vehicle computer so that when said received speed control command is processed, speed reduction is achieved in a predictable manner by controlled adjustments to vacuum control diaphragm.

17. A vehicle authentication and immobilizer control system, comprising:

an RFID equipped vehicle including a computer system for controlling operating functions of said vehicle, said vehicle having a vehicle identification number;

a transmitting and receiving station positioned adjacent an entry zone, said transmitting and receiving station including a database of authorized vehicle identification numbers;
