Abstract

An electronic switch for a device in an automotive vehicle comprises an input pad mounted in an interior of the automotive vehicle, the input pad comprising a sensing mechanism operable to generate a plurality of control signals associated with a plurality of sensing positions of the input pad. The electronic switch further comprises a controller in communication with the input pad and the device, the controller configured to actuate a plurality of switch control functions of the device in response to the plurality of control signals.

Claims

1. An electronic switch for a device in an automotive vehicle, the electronic switch comprising:

an input pad mounted in an interior of the automotive vehicle, the input pad comprising a sensing mechanism operable to generate a plurality of control signals associated with a plurality of sensing positions of the input pad; and

a controller in communication with the input pad and the device, the controller configured to actuate a plurality of switch control functions of the device in response to the plurality of control signals.

2. The electronic switch of claim 1, wherein the sensing mechanism comprises a projected capacitive sensing unit, which allows functionality before the sensing input pad is touched.

3. The electronic switch of claim 1, wherein the input pad is operable either on or behind various materials, these materials being molded or wrapped skins of instrument panels, dashboards, door trims, center consoles, overhead consoles, seats, pillars, and the like.

4. The electronic switch of claim 1, wherein the input pad comprises a continuum of sensing positions.

5. The electronic switch of claim 1, wherein the electronic switch is mountable for optimal access by an operator.

6. The electronic switch of claim 1, wherein the electronic switch generates each of the plurality of control signals by transitory sensing detections of an object by the input pad.

7. The electronic switch of claim 1, wherein the controller is programmable such that each of the plurality of sensing positions of the input pad corresponds to a unique resultant control signal.

8. The electronic switch of claim 1, further comprising a light source so as to be visible and readable whenever surrounding light is insufficient.

9. The electronic switch of claim 8, wherein the light source is controllable by the controller to provide visual feedbacks.

10. The electronic switch of claim 9, wherein the visual feedbacks correspond to control functions that are requested, are being executed, have been executed or are un-executable.

11. The electronic switch of claim 1, further comprising a haptic feedback mechanism controllable by the controller to provide sensory feedbacks in response to predetermined switch control functions.

12. The electronic switch of claim 11, wherein the haptic feedbacks are vibrations and/or mechanical clicks.

13. The electronic switch of claim 1, further comprising markings and/or graphic overlays provided as indicators for corresponding control functions.

14. The electronic switch of claim 13, wherein the markings and/or graphic overlays placed directly on the input pads do not interfere with projective sensing properties of the input pads.

15. The electronic switch of claim 13, wherein the markings and/or graphic overlays are engraved, indented, or printed on covering materials behind which the electronic switch is located.

16. The electronic switch of claim 13, wherein the covering materials are molded or wrapped skins of instrument panels, door trims, center consoles, overhead consoles, seats, or pillars.

17. The electronic switch of claim 1, wherein vehicle applications of the electronic switch include human machine interface (HMI) controls.

18. The electronic switch of claim 1, wherein the electronic switch is retrofitted to existing vehicle devices to replace a factory installed switch or switches.
