Abstract

An interface is in the form of a switch bank for the center stack of a motor vehicle. The switch bank comprises a motor vehicle interior trim component and at least one non-movable switch located behind the interior trim component. The switch is operable to actuate and de-actuate an electrically operated device of the motor vehicle.

Claims

1. A switch bank for a motor vehicle, the switch bank comprising:

a motor vehicle interior trim component; and

at least one non-movable switch located behind the interior trim component, wherein the switch is operable to actuate and de-actuate an electrically operated device of the motor vehicle.

2. The switch bank of claim 1, wherein the interior trim component is molded and has no openings at least where switches are located.

3. The switch bank of claim 1, wherein the interior trim component has tactile features to permit a user to easily identify the location of the switch via tactile sensations.

4. The switch bank of claim 1, wherein the interior trim component has a target area associated with a sensitive operating region of the switch.

5. The switch bank of claim 1, wherein the interior trim component is at least partially transparent or translucent and back-lit to enable a user to visually identify the location of the switch.

6. The switch bank of claim 1, wherein the switch carries indicia that allows a user to associate the switch with the electrically operated device that the switch controls.

7. The switch bank of claim 1, wherein the switch is one of either a resistive, inductive, piezoelectric or capacitive switch.

8. The switch bank of claim 1, wherein the switch is a capacitive switch including at least one dielectric substance and at least one electrode for sensing external disturbance by a stimulus.

9. The switch bank of claim 1, wherein the switch is a capacitive switch including two or more independent dielectric substances, a first one of the dielectric substances having a first electrode and a second one of the dielectric substances having a second electrode, the first and second electrodes having a three-dimensional separation therebetween, the first and second electrodes forming background capacitive sensors for detecting external disturbance by a stimulus, the second electrode having a greater coupling to the external disturbance than the first electrode.

10. The switch bank of claim 1, wherein the switch is a capacitive switch including a first electrode and a second electrode spaced from and surrounding the first electrode so as to be oriented in the same plane, whereby the switch is adapted to generate an electric field that is subject to disturbance by a stimulus, the disturbance being detected by a control circuit, which generates a control signal that controls the operation of the electrically operated device.

11. The switch bank of claim 1, further comprising an audio driver assembly located behind the interior trim component for producing an audio sensation when the switch is operated.

12. The switch bank of claim 1, further comprising an audio driver assembly located behind the interior trim component and sufficiently close to the interior trim component to produce a tactile sensation when the switch is operated.

13. The switch bank of claim 1, wherein the switch is supported on a flexible printed circuit board that is located behind the interior trim component and which conforms to the shape of the interior trim component.

14. The switch bank of claim 1, further comprising a tone generator located behind the interior trim component for producing an audible sensation when the switch is operated.

15. The switch bank of claim 1, further comprising a tactile transducer located behind the interior trim component for producing a tactile sensation when the switch is operated.

16. The switch bank of claim 15, wherein the tactile transducer is in the form of a solenoid that is adapted to be energized to displace a plunger that engages the interior trim component when the switch is operated.

17. The switch bank of claim 1, wherein the sensitivity of the switch is adjustable.

18. The switch bank of claim 1, further comprising an audio driver assembly that is programmable to operate at different frequencies to produce audio or tactile sensations.

19. The switch bank of claim 18, wherein the audio driver assembly also functions as a center speaker for the motor vehicle.

20. The switch bank of claim 1, wherein the switch bank is integrated with a motor vehicle center stack so that the interior trim component and the center stack are molded in a single piece having unitary construction.
