Abstract

The invention relates to an ultrasonic sensor arrangement (2) for a motor vehicle (1) with a cladding component (4, 5, 8, 9) and a first ultrasonic sensor (10 to 13), which with its membrane is disposed on a rear side of the cladding component (4, 5, 8, 9), so that the membrane is designed for transmitting and/or receiving ultrasonic signals through the cladding component (4, 5, 8, 9), wherein the cladding component (4, 5, 8, 9) is a wing (4, 5, 8, 9) for the motor vehicle (1).

Claims

1. An ultrasonic sensor arrangement for a motor vehicle, comprising:

a cladding component; and

a first ultrasonic sensor, which with a membrane of the sensor is disposed on a rear side of the cladding component so that the membrane is designed for transmitting and/or receiving ultrasonic signals through the cladding component,

wherein the cladding component is a wing of the motor vehicle.

2. The ultrasonic sensor arrangement according to claim 1, wherein the wing is made of plastic.

3. The ultrasonic sensor arrangement according to claim 1, wherein the ultrasonic sensor arrangement further comprises a bumper for the motor vehicle and a second ultrasonic sensor, which is disposed with its membrane on a rear side of the bumper, so that the membrane of the second ultrasonic sensor transmits and/or receives ultrasonic signals through the bumper.

4. The ultrasonic sensor arrangement according to claim 3, wherein the first and the second ultrasonic sensors are sensors with a same method of construction with a same resonant frequencies in the uninstalled state.

5. The ultrasonic sensor arrangement according to claim 3, wherein a frequency of the ultrasonic signals transmitted by the first ultrasonic sensor is the same as a frequency of the ultrasonic signals transmitted by the second ultrasonic sensor.

6. The ultrasonic sensor arrangement according to claim 3, wherein the wing is made of a same material as the bumper, at least in a region of the first ultrasonic sensor.

7. The ultrasonic sensor arrangement according to claim 6, wherein at least in the region of the first ultrasonic sensor, the wing has a same thickness as the bumper in a region of the second ultrasonic sensor.

8. A motor vehicle with an ultrasonic sensor arrangement according to claim 1.
