Abstract

A method for controlling an air-conditioning device in a motor vehicle includes the air-conditioning device conveying an air flow into a vehicle interior of the motor vehicle through at least one air outlet opening which is arranged on a lower side of an operating element designed to operate at least one device of the motor vehicle. A detection device detects and signals, by using a detection signal, if a user'"'"'s hand is moved toward the operating element in order to actuate the operating element and/or if the operating element is actuated. The air-conditioning device then reduces and/or diverts the air flow.

Claims

1-11. -11. (canceled)

12. A method for controlling an air-conditioning device in a motor vehicle, the method comprising:

conveying, by the air-conditioning device, an air flow into a vehicle interior of the motor vehicle through at least one air outlet opening arranged on an underside of an operating element configured to operate at least one device of the motor vehicle;

determining, by a detection device, whether to generate a detection signal based on at least one of whether a hand of a user is moved toward the operating element to actuate the operating element, whether the operating element is actuated, and whether a recognition signal is generated by a gesture recognition device which generates the recognition signal only if an extrapolated movement trajectory of the hand is aligned with the operating element;

generating the detection signal, by the detection device, based on the determining; and

adjusting, by at least one of reducing and diverting, the air flow conveyed by the air-conditioning device, based on the detection signal.

13. The method as claimed in claim 12, wherein determining whether to generate the detection signal by the detection device is based on an operating signal from the operating element.

14. The method as claimed in claim 12, wherein determining whether to generate the detection signal by the detection device is based on an additional sensor system different from the operating element.

15. The method as claimed in claim 14, wherein the additional sensor system comprises at least one of a video camera, an infrared camera, a ToF camera, and a capacitive sensor.

16. The method as claimed in claim 12, wherein

determining whether to generate the detection signal by the detection device further comprises:

receiving sensor signals from a plurality of sensors,

determining a probability value for each of the sensor signals indicating whether operation of the operating element is imminent; and

determining a total probability value from all probability values determined for each of the sensor signals; and

wherein the detection device generates the detection signal only if the total probability value satisfies a predetermined triggering criterion.

17. The method as claimed in claim 12, wherein

the air-conditioning device includes an adjusting apparatus arranged at the at least one air outlet opening and is configured to adjust the air flow, and

while operating the adjusting apparatus, adjusting the air flow independently of a position of the hand and actuation of the operating element, and based only on operation of the adjusting apparatus.

18. The method as claimed in claim 12, wherein

the at least one air outlet opening is below a predetermined minimum height, and

determining whether to generate the detection signal by the detection device further comprises determining to generate the detection signal only if the hand is above the predetermined minimum height.

19. The method as claimed in claim 12, wherein

the operating element is a touchscreen, and

adjusting the air flow conveyed by the air-conditioning device changes the air flow based on a location at which a finger of the hand touches the touchscreen by reducing a portion of the air flow flowing under the touch location and maintaining a remaining portion of the air flow flowing under the touch location.

20. A motor vehicle, comprising:

an operating element configured to operate at least one device of the motor vehicle;

an air-conditioning device having at least one air outlet opening arranged on an underside of the operating element and configured to convey an air flow into a vehicle interior of the motor vehicle; and

a detection device configured to determine whether to generate a detection signal based on at least one of whether a hand of a user is moved toward the operating element to actuate the operating element, whether the user actuates the operating element, and whether a recognition signal is generated by a gesture recognition device which generates the recognition signal only if an extrapolated movement trajectory of the hand is aligned with the operating element, and to generate the detection signal based on the determination,

the air-conditioning device being further configured to at least one of reduce and divert the air flow based on the detection signal.

21. The motor vehicle as claimed in claim 20, wherein the operating element is a touchscreen.

22. The motor vehicle as claimed in claim 20, wherein the operating element is a pushbutton.

23. The motor vehicle as claimed in claim 20, wherein the gesture recognition device is disposed at the motor vehicle and includes at least one camera to detect movement of the hand of the user.

24. The motor vehicle as claimed in claim 20, wherein the air-conditioning device diverts the air flow in a downward direction or to a side of the at least one air outlet opening, based on the detection signal.

25. The motor vehicle as claimed in claim 20, further comprising at least one manually operable adjusting apparatus configured to regulate air flow through the at least one air outlet opening,

wherein

when a user manually operates the adjusting apparatus, the air flow is adjusted by the adjusting apparatus based on the manual operation of the adjusting apparatus and independently of a position of the hand of the user and independently of actuation of the operating element.

26. The motor vehicle as claimed in claim 20, wherein

the operating element is a touchscreen, and

the gesture recognition device generates the recognition signal only if the extrapolated movement trajectory of the hand is aligned with an object displayed on the touchscreen.

27. The motor vehicle as claimed in claim 26, wherein the air-conditioning device at least one of reduces and diverts the air flow based on the location of the object displayed on the touchscreen relative to a location of the at least one air outlet opening.
