Abstract

A switch image control system includes at least one first switch having a first image viewable when a backlighting is applied to the at least one first switch. The system also includes at least one second switch having a second image viewable when the backlighting is applied to the at least one second switch. The backlighting is independently applicable to either or both of the at least one first switch and the at least one second switch.

Claims

1. A switch image control system for a vehicle, comprising:

at least one first switch having a first image viewable when a backlighting is applied to said at least one first switch; and

at least one second switch having a second image viewable when said backlighting is applied to said at least one second switch, said backlighting applied to one or both said at least one first switch and said at least one second switch based on at least one operating condition of the vehicle.

2. The switch image control system of claim 1 wherein said at least one operating condition corresponds to an ignition state of the vehicle.

3. The switch image control system of claim 2 wherein said ignition state is based on an ignition switch having a key slot and said state include one or more of:

removed from a key slot, inserted in said key slot and in an OFF position, inserted in said key slot and in an ACC position, and inserted in said key slot and in an ON position.

4. The switch image control system of claim 2 wherein said ignition state includes an off state, an accessory ON state and a run state.

5. The switch image control system of claim 4 wherein the ignition state is determined by a push button of a push button start system.

6. The switch image control system of claim 3 wherein said at least one key position includes:

being inserted in said key slot and being in said ACC position, and being inserted in said key slot and being in said ON position, and wherein said backlighting is applied to one or both said at least one first switch and said at least one second switch based on whether a key is inserted in said key slot and said ignition switch is in said ACC position and based on whether said key is inserted in said key slot and said ignition switch is in said ON position.

7. The switch image control system of claim 1 wherein said at least one operating condition corresponds to an ON or OFF state of a backup power supply of the vehicle.

8. The switch image control system of claim 1 wherein said at least one operating condition corresponds to an ON or OFF state of a lighting system of the vehicle.

9. The switch image control system of claim 8 wherein said lighting system is parking lights of the vehicle, and wherein said backlighting is applied to one or both said at least one first switch and said at least one second switch based on an ON or OFF state of said parking lights.

10. The switch image control system of claim 1 wherein said at least one operating condition corresponds to an ON or OFF state of an audio system of the vehicle or to an ON or OFF state of an HVAC system of the vehicle.

11. The switch image control system of claim 1 wherein said at least one operating condition corresponds to an ON or OFF state of a communication system of the vehicle.

12. The switch image control system of claim 11 wherein said communication system is a hands free call system of the vehicle, and wherein said backlighting is applied to one or both said at least one first switch and said at least one second switch based on an ON or OFF state of said hands free call system.

13. The switch image control system of claim 1 wherein said first image is viewable only when said backlighting is applied to said at least one first switch, otherwise said at least one first switch has a black-out appearance, and said second image is viewable only when said backlighting is applied to said at least one second switch, otherwise said at least one second switch has a black-out appearance.

14. The switch image control system of claim 1 wherein said first image and said second image are not visible with ambient lighting or front side lighting when said backlighting is not applied to said at least one first switch and said at least one second switch.

15. The switch image control system of claim 1 wherein application of said backlighting to said at least one first switch corresponds with an operational status of said at least one first switch, and application of said backlighting to said at least one second switch corresponds to an operational status of said at least one second switch.

16. A switch image control system for a vehicle, comprising:

a first group of switches having first images viewable thereon when a backlighting is applied thereto, said first group of switches corresponding to a first vehicle sub-system; and

a second group of switches having second images viewable thereon when said backlighting is applied thereto, said second group of switches corresponding to a second vehicle sub-system, said backlighting applied to one or both of said first group of switches and said second group of switches based on ignition state of the vehicle, an ON or OFF state of a backup power supply of the vehicle, an ON or OFF state of a lighting system of the vehicle, an ON or OFF state of an audio system of the vehicle, an ON or OFF state of a HVAC system, and an ON or OFF state of a communication system of the vehicle.

17. The switch image control system of claim 16 wherein said first group of switches includes HVAC control switches and said first vehicle sub-system is an HVAC system, and wherein said second group of switches includes audio control switches and said second vehicle sub-system is an audio system.

18. The switch image control system of claim 17 further including:

an audio power switch having a third image viewable when said backlighting is applied to said audio power switch based on at least one of;

said ignition state of the vehicle, said ON or OFF state of said backup power supply of the vehicle, said ON or OFF state of said lighting system of the vehicle, said ON or OFF state of an audio system of the vehicle, an ON or OFF state of a HVAC system, and said ON or OFF state of said communication system of the vehicle.

19. The switch image control system of claim 18 wherein said backlighting is applied to each of said first group of switches, said second group of switches and said audio power button switch based on each of said ignition state of the vehicle, said ON or OFF state of said backup power supply of the vehicle, said ON or OFF state of a lighting system of the vehicle, said ON or OFF state of said audio system of the vehicle, an ON or OFF state of a HVAC system, and said ON or OFF state of said communication system of the vehicle.

20. A switch image control method for a vehicle, comprising:

providing at least one first switch having a first image;

providing at least one second switch having a second image; and

selectively and independently backlighting one or both of said at least one first switch to illuminate said first image and said at least one second switch to illuminate said second image based on at least one operating condition of the vehicle.

21. The switch image control method of claim 20 wherein said at least one operation condition of the vehicle includes at least one of:

an ignition state of the vehicle, an ON or OFF state of a backup power supply of the vehicle, an ON or OFF state of a lighting system of the vehicle, an ON or OFF state of an audio system of the vehicle, an ON or OFF state of a HVAC system, and an ON or OFF state of a communication system of the vehicle.

22. The switch image control method of claim 20 further including:

providing an audio power switch having a third image; and

selectively and independently backlighting said audio power switch to illuminate said third image based on said at least one operating condition of the vehicle.
