Abstract

In a method for wireless communication between a vehicle, particularly a motor vehicle, and an external service facility, wherein at least one communication signal is sent to the vehicle by the service facility, it is provided as essential for the purposes of the invention that the communication signal is a sound signal, and that the communication signal is captured by at least one structure-borne sound sensor installed in the vehicle.

First claim

The invention claimed is:

1. A method for wireless communication between a vehicle, particularly a motor vehicle, and an external service facility, wherein at least one first communication signal is sent to the vehicle by the external service facility,
wherein the at least one first communication signal is a sound signal and the at least one first communication signal is captured by at least one structure-borne sound sensor installed in the vehicle,
wherein the at least one structure-borne sound sensor is embodied as a piezoelectrically active element that captures structure-borne sound,
wherein at least one second communication signal is transmitted to the external service facility via the at least one structure-borne sound sensor, and
wherein the at least one structure-borne sound sensor is mounted in the vehicle and arranged to detect contacts between an outer shell of the vehicle and external objects by capturing structure-borne sound conducted to the outer shell of the vehicle, and
wherein a voltage signal is applied to the structure borne sound sensor so that the piezoelectrically active element is caused to oscillate by a piezoelectric effect, thereby being enabled to transmit said at least one second communication signal.

2. The method according to claim 1 , wherein the at least one second communication signal is transmitted by the at least one structure-borne sound sensor in the form of an ultrasound signal.

3. The method according to claim 1 , wherein the at least one second communication signal is sent to the external service facility by the at least one structure-borne sound sensor as an authentication signal for the unique authentication of the vehicle.

4. The method according to claim 1 , wherein a control signal for operating an actuator of the motor vehicle is sent to the motor vehicle from the external service facility.

5. The method according to claim 4 , wherein the actuator is a closure device for a power supply interface and that the power supply interface is uncovered by the actuator upon receipt of the control signal.

6. A vehicle, particularly a motor vehicle, having at least one structure-borne sound sensor being embodied as a piezoelectrically active element that captures structure-borne sound and having at least one evaluation device for evaluating signals captured by the at least one structure-borne sound sensor,
wherein the at least one structure-borne sound sensor is designed to transmit an ultrasound signal from an external service facility,
wherein the at least one structure-borne sound sensor is designed to transmit an ultrasound signal to said external service facility, and
wherein the at least one structure-borne sound sensor is mounted in the vehicle and arranged to detect contacts between an outer shell of the vehicle and external objects by capturing structure-borne sound conducted to the outer shell of the vehicle, and
wherein a voltage signal is applied to the structure borne sound sensor so that the piezoelectrically active element is caused to oscillate by a piezoelectric effect, thereby being enabled to transmit the ultrasound signal to said external service facility.

7. The vehicle according to claim 6 , wherein the vehicle has at least one actuator, the vehicle has at least one control device for controlling the actuator, and the control device is connected in signal-conducting manner to at least one actuator and at least one evaluation device.

8. The vehicle according to claim 7 , wherein the actuator is a closure device for a power supply interface, particularly an opening mechanism for a closure flap.
