Abstract

A motor vehicle tracking and information system that uses a radio-frequency electronic vehicle license plate in conjunction with roadside receivers and an information system architecture. The system is used to identify and track vehicles, detecting vehicles operating in violation of the law, and automatically issuing citations.

Claims

1. A vehicle tracking system, the system comprising:

a unitary RF electronic license plate attached to a vehicle, the license plate having integrated therein tamper-proof ID and transmitting components, the electronic transmitting components capable of transmitting radio-frequency signals containing information about the license plate and the vehicle;

a series of spaced roadside or mobile receivers for detecting vehicles and decoding the transmission signals into data; and

a Central Information System (CIS) for tracking vehicles, for analyzing violations of law, and for making the data useful to law enforcement, industry, and private citizens.

2. The vehicle tracking system of claim 1 wherein the license plate is constructed with embedded ID electronics which provide a unique electronic signature to the license plate, with security features to detect tampering.

3. The vehicle tracking system of claim 2 wherein the code structure of the unique electronic signature and visible status illumination indicates if the plate has illegally been placed on another vehicle.

4. The vehicle tracking system of claim 2 wherein the electronic components comprise an antenna, an encoder and transmitter, multiple one-time programmable (OTP) memory circuits, an erasable programmable read-only memory (EPROM), a CPU and timing circuit, illumination electronics, security electronics, a battery and power conditioning, all integrated and embedded into the license plate.

5. The vehicle tracking system of claim 4 wherein the electronic transmitting components are mounted to a dielectric substrate in the license plate and encapsulated, or encased in composite materials to prevent tampering.

6. The vehicle tracking system of claim 4 wherein an asynchronous transmission mode, in which the plate randomly transmits the electronic code structure, provides inherent RF collision avoidance with other transponders within range of the receiver.

7. The vehicle tracking system of claim 4 wherein the electronic transmitting components are integrated into a unitary plate having retro-reflective letters and numbers to visually convey the identity of the vehicle, and electronic illumination for tamper-detection and for conveying operational status and other information.

8. The vehicle tracking system of claim 4 wherein a OTP chip is programmed with the license plate number at the time of manufacture and a second OTP chip is reserved for the vehicle ID number and is programmed by the Department of Motor Vehicles when the plate is issued, providing unique identity to the plate.

9. The vehicle tracking system of claim 4 wherein the EPROM is used by law enforcement for programming status illumination electronics on the plate.

10. The vehicle tracking system of claim 2 further comprising an electrical umbilical cord between the plate and the vehicle, from which umbilical cord the electronics in the plate derive power, and through which the plate communicates to the vehicle'"'"'s on-board computer, if so equipped.

11. The vehicle tracking system of claim 1 wherein the receiver uplinks stored records periodically to a Central Information System (CIS) by means of a communication link comprised of RF and/or landline components.

12. The vehicle tracking system of claim 1 wherein through the Central Information System insurance records, inspection records, DMV records, emissions records, commercial vehicle permit records, law enforcement records and other pertinent data files are utilized and accessible.

13. The vehicle tracking system of claim 12 wherein the Central Information System further comprises a dial-up access means for law enforcement agencies to access the records.

14. The vehicle tracking system of claim 12 wherein the Central Information System further comprises browser-based internet access to tracking information for use by industry and private consumers.

15. The vehicle tracking system of claim 1 wherein the receiver assigns a time/date stamp to each record, enabling the Central Information System to identify all vehicles which were in the proximity of a crime scene at a particular time.

16. The vehicle tracking system of claim 1 wherein the Central Information System checks for compliance with vehicle registration, insurance, inspection, emission requirements and commercial vehicle permits by integrating data from the Department of Motor Vehicles (DMV), law enforcement agencies, insurance companies, emissions testing records and other pertinent data sources.

17. The vehicle tracking system of claim 1 wherein by placing roadside receivers a few miles apart, average vehicle velocity can be determined.

18. The vehicle tracking system of claim 1 wherein receivers are installed at railroad gate crossings and operate in conjunction with signaling means to detect and identify vehicles crossing the tracks when warning lights are flashing, and/or gates are down.

19. The vehicle tracking system of claim 1 wherein receivers operate in conjunction with signaling means at traffic intersections.

20. The vehicle tracking system of claim 1 wherein through the Central Information System citations for moving vehicle violations are automatically processed and issued (e.g., via. Certified mail to the registered vehicle owner).

21. The vehicle tracking system of claim 1 wherein receivers are installed at toll booths for faster vehicle processing and automatic toll invoicing.

22. The vehicle tracking system of claim 1 wherein private enterprise can install readers for local security purposes, such as for limiting vehicular access to secure areas or for monitoring vehicles at fuel pumps in order to identify vehicles which drive off without paying.

23. The vehicle tracking system of claim 14 wherein through the Central Information System individuals and private industry can access information on specific vehicle location for the purpose of scheduling and tracking commercial shipments, tracking rental vehicles, and tracking private vehicles.

24. The vehicle tracking system of claim 1 wherein the Central Information System is used to facilitate traffic studies for community and transportation planning by reporting the specific demographics of vehicular traffic to more accurately assess traffic patterns.

25. The vehicle tracking system of claim 1 wherein the Central Information System is capable of analyzing traffic patterns across country borders for the purpose of identifying vehicles associated with smuggling, drug trafficking, or other illegal activities.

26. The vehicle tracking system of claim 1 including technologies and/or additional subsystems necessary to prevent consumer electronic jamming devices from rendering receivers ineffective.
