Abstract

A system and method for controlling an in-vehicle entertainment system in a vehicle having a remote keyless entry system. A receiver to be mounted on-board the vehicle is provided in communication with a vehicle access device associated with the remote keyless entry system and receives a radio frequency vehicle access signal for use in controlling a vehicle access function. The receiver is further provided in communication with the in-vehicle entertainment system and receives a radio frequency command signal for use in controlling the in-vehicle entertainment system.

Claims

1. In a vehicle having a remote keyless entry system and an in-vehicle entertainment system, a system for controlling the in-vehicle entertainment system comprising:

a remote transmitter for transmitting a radio frequency vehicle access signal for use in controlling a vehicle access function; and

a receiver to be mounted on-board the vehicle for receiving the vehicle access signal, the receiver to be provided in communication with a vehicle access device for performing the vehicle access function, the receiver further to be provided in communication with the in-vehicle entertainment system and for receiving a radio frequency command signal for use in controlling the in-vehicle entertainment system.

2. The system of claim 1 further comprising a remote transmitter for transmitting the radio frequency command signal.

3. The system of claim 1 wherein the receiver is provided in communication with the in-vehicle entertainment system and the vehicle access device using a vehicle bus.

4. The system of claim 2 wherein the in-vehicle entertainment system comprises a compact disk player, and the radio frequency command signal comprises a signal for use in playing a compact disk.

5. The system of claim 2 wherein the in-vehicle entertainment system comprises a monitor and a video cassette recorder, and the radio frequency command signal comprises a signal for use in playing a video cassette.

6. The system of claim 2 wherein the in-vehicle entertainment system comprises a monitor and a digital video disk player, and the radio frequency command signal comprises a signal for use in playing a digital video disk.

7. The system of claim 4 wherein the vehicle access device comprises a vehicle door lock mechanism and the vehicle access function is a door unlock function.

8. The system of claim 1 wherein the receiver is for receiving a further radio frequency signal associated with a further vehicle device.

9. The system of claim 8 wherein the further vehicle device comprises a tire pressure monitor and the further radio frequency signal comprises a tire pressure signal.

10. In a vehicle having a remote keyless entry system and an in-vehicle entertainment system, a system for controlling the in-vehicle entertainment system comprising:

a remote transmitter for transmitting a radio frequency command signal for use in controlling the in-vehicle entertainment system; and

a receiver to be mounted on-board the vehicle, the receiver to be provided in communication with the in-vehicle entertainment system and for receiving the command signal, the receiver further to be provided in communication with a vehicle access device and for receiving a radio frequency vehicle access signal for use in controlling the vehicle access device.

11. The system of claim 10 further comprising a remote transmitter for transmitting the radio frequency vehicle access signal.

12. The system of claim 10 wherein the receiver is provided in communication with the in-vehicle entertainment system and the vehicle access device using a vehicle bus.

13. The system of claim 12 wherein the in-vehicle entertainment system comprises a compact disk player, and the radio frequency command signal comprises a signal for use in playing a compact disk.

14. The system of claim 10 wherein the in-vehicle entertainment system comprises a monitor and a video cassette recorder, and the radio frequency command signal comprises a signal for use in playing a video cassette.

15. The system of claim 10 wherein the in-vehicle entertainment system comprises a monitor and a digital video disk player, and the radio frequency command signal comprises a signal for use in playing a digital video disk.

16. The system of claim 13 wherein the vehicle access device comprises a vehicle door lock mechanism and the vehicle access signal is for use in controlling the vehicle door lock mechanism to perform a door unlock function.

17. The system of claim 10 wherein the receiver is for receiving a further radio frequency signal associated with a further vehicle device.

18. The system of claim 17 wherein the further vehicle device comprises a tire pressure monitor and the further radio frequency signal comprises a tire pressure signal.

19. In a vehicle having a remote keyless entry system and an in-vehicle entertainment system, a method for controlling the in-vehicle entertainment system comprising:

transmitting a radio frequency vehicle access signal from a remote transmitter associated with the remote keyless entry system;

transmitting a radio frequency entertainment system command signal from a remote transmitter associated with the in-vehicle entertainment system;

receiving at a vehicle mounted receiver the radio frequency vehicle access signal; and

receiving at the vehicle mounted receiver the radio frequency command signal, wherein the vehicle mounted receiver is provided in communication with the in-vehicle communication system and with a vehicle access device associated with the remote keyless entry system.

20. The method of claim 19 further comprising receiving at the vehicle mounted receiver a further radio frequency signal associated with a further vehicle device.
