Control device for a motor vehicle
View Patent ↗A control device for a motor vehicle, comprising a display element, a projection unit, and a capacitive proximity sensor. At least one control element can be projected onto a visible surface of the display element by the projection unit. Actuation of the control element can be detected by the capacitive proximity sensor.
1. A control device for a motor vehicle, comprising
a display element;
a projection apparatus configured to project at least one control element onto a viewing surface of the display element, wherein the viewing surface is on a first side of the display element, wherein the projection apparatus comprises:
a light source and at least one lens located on a second side of the display element opposite the first side of the display element; and
a reflection surface located on a second, opposite side of the display element; and
a capacitive proximity sensor configured to detect an actuation of the control element,
wherein the reflection surface is a different surface from the viewing surface and faces the viewing surface, and wherein the reflection surface is configured to receive light beams from the light source and the at least one lens and to reflect reflected light beams from the reflection surface toward the viewing surface and onto the viewing surface.
2. The control device according to claim 1 , wherein the display element is non-conductive.
3. The control device according to claim 2 , wherein the capacitive proximity sensor is arranged at a side of the display element that lies opposite the viewing surface.
4. The control device according to claim 2 , comprising:
a shielding apparatus for selectively influencing an effective region of the capacitive proximity sensor.
5. The control device according to claim 2 , wherein the projection apparatus comprises:
the light source configured to generate the light beams;
a plurality of lenses, including the at least one lens, configured to capture and parallelize the light beams;
a projection object to be projected; and
the reflection surface with which the reflected light beams are projected onto the viewing surface as the control element.
6. The control device according to claim 2 , comprising:
an evaluation apparatus configured to generate a switch signal corresponding to the detected actuation, wherein the switch signal is configured to control and/or trigger a function.
7. The control device according to claim 1 , wherein the display element is a textile, a leather, and/or an imitation leather.
8. The control device according to claim 7 , wherein the capacitive proximity sensor is arranged at a side of the display element that lies opposite the viewing surface.
9. The control device according to claim 1 , wherein the capacitive proximity sensor is arranged at a side of the display element that lies opposite the viewing surface.
10. The control device according to claim 9 , comprising:
a shielding apparatus for selectively influencing an effective region of the capacitive proximity sensor.
11. The control device according to claim 9 , wherein the projection apparatus comprises:
the light source configured to generate the light beams;
a plurality of lenses, including the at least one lens, configured to capture and parallelize the light beams;
a projection object to be projected; and
the reflection surface with which the reflected light beams are projected onto the viewing surface as the control element.
12. The control device according to claim 9 , comprising:
an evaluation apparatus configured to generate a switch signal corresponding to the detected actuation, wherein the switch signal is configured to control and/or trigger a function.
13. The control device according to claim 1 , comprising:
a shielding apparatus for selectively influencing an effective region of the capacitive proximity sensor.
14. The control device according to claim 13 , comprising:
an evaluation apparatus configured to generate a switch signal corresponding to the detected actuation, wherein the switch signal is configured to control and/or trigger a function.
15. The control device according to claim 1 , wherein the projection apparatus comprises:
the light source configured to generate the light beams;
a plurality of lenses, including the at least one lens, configured to capture and parallelize the light beams;
a projection object to be projected; and
the reflection surface with which the reflected light beams are projected onto the viewing surface as the control element.
16. The control device according to claim 1 , wherein the reflection surface is configured to be arranged at a three-dimensional control device configured to control a function of the motor vehicle.
17. The control device according to claim 1 , comprising:
an evaluation apparatus configured to generate a switch signal corresponding to the detected actuation, wherein the switch signal is configured to control and/or trigger a function.
