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.

2. The switch image control system of claim 1 wherein said at least one operating condition corresponds to at least one of 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 heating, ventilation, air conditioning system (HVAC system) of the vehicle, an ON or OFF state of a communication system of the vehicle.

3. The switch image control system of claim 2 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.

4. The switch image control system of claim 2 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.

5. The switch image control system of claim 1 further including:

a first subsystem controller corresponding to said first subsystem and a second subsystem controller corresponding to said second subsystem wherein said first sub-system corresponds to said first switch and said second sub-system corresponds to said second switch.

6. The switch image control system of claim 5 wherein input of said first switch is communicated to said first sub-system controller and input of said second switch is communicated to said second sub-system controller wherein a backlighting controller receives indications from at least one of said first sub-system controller or second sub-system controller based on at least one of input of said first switch, or input of said second switch.

7. The switch image control system of claim 6 wherein said backlighting controller provides actuation to initialize said backlighting to be applied to one or both of said first switch or said second switch based on at least one of the following:

said operating condition of the vehicle, receiving an indication from said first sub-system controller, or receiving said indication from said second sub-system controller.

8. The switch image control system of claim 7 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.

9. 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.

10. The switch image control system of claim 9 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.

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

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

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, wherein said second images are representative of a function of said second group of switches; and

a third switch having a third image viewable thereon when said backlighting is applied thereto, wherein said third image is representative of a function of said third switch,

wherein one or more of said first group of switches, said second group of switches, and said third switch are selectively and independently backlit to illuminate the images thereon based on at least one operating condition of the vehicle,

wherein the operating condition represents the function of at least one of the at least one first group of switches or the at least one second group of switches.

12. The switch image control system of claim 11 wherein said first group of switches includes a heating, ventilation, air conditioning system (HVAC system) control switches and said first vehicle sub-system is the HVAC system, and wherein said second group of switches includes audio control switches and said second vehicle sub-system is an audio system.

13. The switch image control system of claim 12 wherein said backlighting of said first group of switches indicates said HVAC system control switches are active, and said backlighting of said second group of switches indicates said audio control switches are active.

14. The switch image control system of claim 13 wherein said backlighting is applied to each of said first group of switches, and said second group of switches based on at least one of an ON or OFF state of a lighting system of the vehicle, an ON or OFF state of said audio system of the vehicle, an ON or OFF state of said HVAC system of the vehicle, and an ON or OFF state of a communication system of the vehicle.

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

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

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; and

a third switch having a third image viewable thereon when said backlighting is applied thereto,

wherein one or more of said first group of switches, said second group of switches, and said third switch are selectively and independently backlit to illuminate the images thereon based on at least one operating condition of the vehicle, and

wherein said third switch includes an audio power switch and said backlighting is applied to said audio power switch based on at least one of;

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 heating, ventilation, air conditioning system (HVAC system) of the vehicle, and an ON or OFF state of a communication system of the vehicle.

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

providing at least one first switch having a first image corresponding to a first vehicle sub-system, wherein said first image is representative of a function of said at least one first switch;

providing at least one second switch having a second image corresponding to a second vehicle sub-system, wherein said second image is representative of a function of said at least one second switch; 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,

wherein the operating condition represents the function of at least one of the at least one first switch or the at least one second switch.

17. The switch image control method of claim 16 wherein said at least one operating condition corresponds to at least one of 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 heating, ventilation, air conditioning system (HVAC system) of the vehicle, or an ON or OFF state of a communication system of the vehicle.
