Sensor device and method for recording at least one contact event on a vehicle

Abstract

A sensor device for detecting at least one contact event on a vehicle, in particular a motor vehicle, with at least one impact sound sensor for detecting at least one impact sound signal. At least one impact sound sensor has at least one signal-transferring connection to at least one signal processing means already existing in the vehicle and associated with at least one other sensor means. With this arrangement, at least one impact sound sensor has an impact-sound-transmitting connection to a section of the outer shell of the vehicle. This allows contact events on the vehicle to be detected.

1 . A method for detecting at least one contact event on a vehicle, in particular a motor vehicle, with at least one impact sound sensor for detecting at least one impact sound signal, and with at least one ultrasound sensor, in particular with a sensor device,
 wherein an approximation of an object in direction of the vehicle is detected and/or an approximation of the vehicle in direction of an object is detected by the ultrasound sensor and in that when detecting an approximation, the impact sound sensor is switched into a ready-to-receive state.
