Abstract

Apparatus for use in a vehicle equipped with a vehicle-to-vehicle communication system. A remote keyless entry fob is provided for remote control of vehicle access. The fob includes a receiver for receiving a message broadcast by the vehicle-to-vehicle communication system and a memory for storing at least some elements of said message.

Claims

1. A vehicle safety system comprising:

a vehicle-based communication system adapted to transmit and receive wireless vehicle-to-vehicle (V2V) communication signals and to receive wireless remote keyless entry (RKE) communication signals; and

a fob adapted to transmit the wireless RKE communication signals and to receive the wireless V2V communication signals, wherein the vehicle-based communication system and the fob are configured such that the V2V communication signals and the RKE communication signals are transmitted and received on a shared communication frequency.

2. The vehicle safety system recited in claim 1, wherein the RKE communication signal comprises an RKE message.

3. The vehicle safety system recited in claim 2, wherein the vehicle-based communication system is configured to receive the wireless signal from the fob and to respond to the RKE message in the wireless signal transmitted by the fob.

4. The vehicle safety system recited in claim 1, wherein the fob comprises a transmitter and a receiver for communicating with the vehicle-based communication system.

5. The vehicle safety system recited in claim 1, wherein the fob comprises a transceiver for communicating with the vehicle-based communication system.

6. The vehicle safety system recited in claim 1, wherein the vehicle-based communication system comprises at least one of a transmitter, a receiver, and a transceiver for communicating with V2V communication systems of other vehicles within a predetermined vicinity and for communicating with the fob.

7. The vehicle safety system recited in claim 1, wherein the V2V communication frequency is a frequency within or above the high frequency radio frequency spectrum.

8. The vehicle safety system recited in claim 1, wherein the V2V communication frequency is a 5.8 GHz frequency.

9. The vehicle safety system recited in claim 1, wherein the fob is configured to re-broadcast the V2V communication signals received from the vehicle-based communication system to other vehicles within a predetermined vicinity of the fob.

10. The vehicle safety system recited in claim 1, wherein the fob is configured to adjust a fob signal transmission power level based on GPS information related to the location of the vehicle.

11. The vehicle safety system recited in claim 10, wherein the fob is configured to obtain the GPS information from at least one of the V2V communication signal received from the vehicle-based communication system, a GPS receiver inside the fob, and a device external to the fob.

12. The vehicle safety system recited in claim 1, wherein the vehicle-based communication system is further adapted to receive V2V communication signals from other vehicles within a predetermined vicinity and provide the recorded messages to onboard vehicle systems and subsystems for display or responsive action.

13. The vehicle safety system recited in claim 1, wherein the vehicle-based communication system is adapted to operate while the vehicle is operating, the vehicle-based communication system being adapted to notify nearby vehicles of safety data comprising at least one of velocity, direction, location, linear acceleration, and rotational acceleration.

14. The vehicle safety system recited in claim 1, wherein the vehicle-based communication system is adapted to remain powered and active for a predetermined period of time after the vehicle ignition is switched off in order to broadcast one or more final V2V communication signals, and wherein the fob is adapted to store at least a portion of the information received in the one or more final V2V communication signals in memory.

15. The vehicle safety system recited in claim 14, wherein the one or more final V2V communication signals comprise at least one of vehicle stationary status information, location information, and vehicle safety information.

16. The vehicle safety system recited in claim 14, wherein the fob is adapted to receive and store only the information in the one or more final V2V communication signals.

17. The vehicle safety system recited in claim 1, wherein the fob is adapted to receive and verify a vehicle ID portion of the V2V communication signal to verify that the signal is from the vehicle associated with the fob.

18. The vehicle safety system recited in claim 17, wherein the fob is adapted to ignore V2V communication signals from other vehicles based on the vehicle ID portion.

19. The vehicle safety system recited in claim 1, wherein the fob is adapted to store the information received in the V2V communication signal in the memory within the fob.

20. The vehicle safety system recited in claim 1, wherein the fob is adapted to permit a user to access the vehicle location information and other V2V communication signal elements including information regarding vehicle malfunctions associated with vehicle safety.

21. The vehicle safety system recited in claim 1, wherein the fob is adapted to provide selected elements of the V2V communication signal to the owner via an indicator comprising at least one of a display on the fob, a cell phone, a tablet computer, a personal or notebook computer, a television via at least one of a near field communication link, a low-power RF communication protocol, and a USB connection.

22. The vehicle safety system recited in claim 1, wherein the fob is adapted to utilize GPS location information from the V2V communication signal to determine the location of the vehicle relative to the fob.

23. The vehicle safety system recited in claim 1, wherein the fob comprises an embedded GPS receiver and is adapted to compare current GPS location of the fob with stored GPS location of the vehicle to determine the location of the vehicle relative to the fob.

24. The vehicle safety system recited in claim 1, wherein the fob is adapted to cooperate with an external device having GPS capabilities to determine the location of the vehicle relative to the fob.

25. The vehicle safety system recited in claim 1, wherein the fob and the V2V communication system are adapted to communicate on the same frequency, the fob being adapted to obtain safety information and location information from the V2V communication system and provide the safety and location information to an external system for at least one of vehicle diagnosis, vehicle locating, and vehicle information recordation and/or display.

26. The vehicle safety system recited in claim 1, wherein the fob is adapted to periodically ping the V2V communication system for information related to vehicle security systems, comprising glass breakage information, door lock information, vehicle ignition information, vehicle impact information, and vehicle security system information.
