Abstract

A method for operating a plurality of acoustic signal transmitters of a motor vehicle is disclosed, wherein booking information is obtained from an external computing unit by means of a control system of the motor vehicle. By means of the control system, a first part of the plurality of acoustic signal transmitters is deactivated depending on the booking information. By means of the control system, a control signal is generated for each of the acoustic signal transmitters of a second part of acoustic signal transmitters to generate an acoustic output.

First claim

What is claimed is:

1 - 10 . (canceled)

11 . A method for operating a plurality of acoustic signal transmitters of a motor vehicle, comprising:
obtaining booking information from an external processor using a control system of the motor vehicle; deactivating a first part of the plurality of acoustic signal transmitters depending on the booking information using the control system; generating a control signal using the control system for each of the acoustic signal transmitters of a second part of acoustic signal transmitters of the plurality of acoustic signal transmitters, which includes at least two of the plurality of acoustic signal transmitters, to generate an acoustic output.

12 . The method of claim 11 , wherein the control signals are generated depending on the booking information and/or depending on a preset sound profile.

13 . The method of claim 11 , comprising:
generating at least one sensor signal depending on a position and/or orientation of a seat of the motor vehicle using a sensor system of the motor vehicle; and generating the control signals depending on the at least one sensor signal.

14 . The method of claim 13 , comprising:
generating a rotary encoder signal depending on a rotational position of the seat by a rotary encoder of the sensor system; and generating the control signals depending on the rotary encoder signal.

15 . The method of claim 14 , wherein the rotational position corresponds to a rotational angle around a rotational axis, which is at least approximately parallel to a vehicle vertical axis of the motor vehicle.

16 . The method of claim 13 , comprising:
generating image data, which represents the seat at least partially, using a camera system of the motor vehicle; and generating the control signals depending on the image data.

17 . The method of claim 13 , comprising:
generating a seat occupancy sensor signa depending on a seat occupancy of the seat by a seat occupancy sensor of the motor vehicle; and generating the control signals depending on the seat occupancy sensor signal.

18 . A control system for a motor vehicle with a plurality of acoustic signal transmitters, wherein
the control system comprises a communication interface, which is configured to obtain booking information from an external processor; the control system comprises at least one control unit, which is configured to deactivate a first part of the plurality of acoustic signal transmitters depending on the booking information; and the at least one control unit is configured to generate a control signal for each of the acoustic signal transmitters of a second part of acoustic signal transmitters of the plurality of acoustic signal transmitters, which includes at least two of the plurality of acoustic signal transmitters, to generate an acoustic output.

19 . The control system of claim 18 , wherein
the control system comprises a sensor system, which is configured to generate at least one sensor signal depending on a position and/or orientation of a seat of the motor vehicle; and the at least one control unit is configured to generate the control signals depending on the at least one sensor signal.

20 . A motor vehicle with a plurality of acoustic signal transmitters and a control system of claim 18 .

21 . The method of claim 12 , comprising:
generating at least one sensor signal depending on a position and/or orientation of a seat of the motor vehicle using a sensor system of the motor vehicle; and generating the control signals depending on the at least one sensor signal.

22 . The method of claim 11 , comprising:
generating a rotary encoder signal depending on a rotational position of the seat by a rotary encoder of the sensor system; and generating the control signals depending on the rotary encoder signal.

23 . The method of claim 12 , wherein the rotational position corresponds to a rotational angle around a rotational axis, which is at least approximately parallel to a vehicle vertical axis of the motor vehicle.

24 . The method of claim 14 , comprising:
generating image data, which represents the seat at least partially, using a camera system of the motor vehicle; and generating the control signals depending on the image data.

25 . The method of claim 14 , comprising:
generating image data, which represents the seat at least partially, using a camera system of the motor vehicle; and generating the control signals depending on the image data.

26 . The method of claim 14 , comprising:
generating a seat occupancy sensor signa depending on a seat occupancy of the seat by a seat occupancy sensor of the motor vehicle; and generating the control signals depending on the seat occupancy sensor signal.

27 . The method of claim 15 , comprising:
generating a seat occupancy sensor signa depending on a seat occupancy of the seat by a seat occupancy sensor of the motor vehicle; and generating the control signals depending on the seat occupancy sensor signal.

28 . The method of claim 16 , comprising:
generating a seat occupancy sensor signa depending on a seat occupancy of the seat by a seat occupancy sensor of the motor vehicle; and generating the control signals depending on the seat occupancy sensor signal.
