Abstract

Modular auxiliary processor circuitry, capable of performing telematics services, including wireless communications, diagnostic assessment and reporting, location based services, and internetworking, couples with a vehicle head unit through an auxiliary processing module interface. When so coupled, the auxiliary processing module circuitry can perform tasks, services, functions, and aspect that a lower-capability processor of the head unit cannot perform as quickly or as efficiently, if at all. When the auxiliary processor module is coupled and active, its display output can couple to a display device either permanently fixed in the vehicle, or portable and mobile with respect to the vehicle, through conductors or a wireless link. When the auxiliary processor circuitry'"'"'s output couples to the display device, software running on the head unit, or the auxiliary processor module, may decouple the head unit from the display device unless a user interface requests its services, such as tuning an AM/FM radio circuit.

Claims

1. An auxiliary processing module, comprising:

processor circuitry configured for performing wireless communications, graphics processing, and application processing;

contacts that pass signals of the processor circuitry and that mate with complementary contacts of an auxiliary processing module interface connected to a vehicle'"'"'s audio-visual control unit when the auxiliary processing module has been coupled with the auxiliary processing module interface; and

wherein the wireless communications, graphics processing, and application processing supplement processing by the audio-visual control unit when the auxiliary processing module has been selected with a user interface.

2. The device of claim 1 wherein the processor circuitry includes a system on a chip.

3. The device of claim 1 wherein the processor circuitry includes an integrated circuit.

4. The device of claim 1 wherein the processor circuitry has a performance capability that exceeds that of a processor of the audio/visual control module.

6. A system, comprising:

an auxiliary processing module, comprising;

processor circuitry configured for performing wireless communications, graphics processing, and application processing;

contacts that pass signals of the processor circuitry and that mate with complementary contacts of an auxiliary processing module interface connected to a vehicle'"'"'s audio-visual control unit when the auxiliary processing module has been coupled with the auxiliary processing module interface;

wherein the wireless communications, graphics processing, and application processing supplement processing by the audio-visual control unit when the auxiliary processing module is selected using software running on the audio/visual control unit;

a display device coupled to the audiovisual control unit; and

a switching means that operates when use of the auxiliary processing module has been selected to couple output from the auxiliary processing module to the display device.

7. The device of claim 6 wherein the processor circuitry includes a system on a chip.

8. The device of claim 6 wherein the processor circuitry includes an integrated circuit.

9. The device of claim 6 wherein the processor circuitry has a performance capability that exceeds the processing capability of a processor of the audio/visual control module.

10. The system of claim 6 wherein the auxiliary processing module interface includes a slot.

11. The system of claim 6 wherein, the auxiliary processing module interface connection and the vehicle'"'"'s audio-visual control unit compose a head unit.

12. The auxiliary processing module of claim 6 wherein use of the auxiliary processing module has been selected using a user interface.

13. The auxiliary processing module of claim 12 wherein the user interface is generated by software running on the audio/visual control unit.

14. The auxiliary processing module of claim 12 wherein the user interface is generated by software running on they auxiliary processing module.
