Abstract
With 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 comprises 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 comprises 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.
Claims8
A sensor device for recording at least one contact event at a vehicle, in particular a motor vehicle, with at least one impact sound sensor for detecting at least one impact sound signal,
- wherein at least one impact sound sensor comprises at least one signal-transferring connection to at least one signal processing means associated with at least one other sensor means already existing in the vehicle,
- in that at least one impact sound sensor comprises at least one impact-sound-transmitting connection to at least one section of the outer shell of the vehicle,
- in that at least one already existing signal processing means is associated with at least one ultrasound sensor,
- in that the ultrasound sensor comprises at least one mounting part for attaching the ultrasound sensor in an area of the outer shell of a vehicle,
- and in that the impact sound sensor is arranged between the mounting part and the outer shell of the vehicle.
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 according to the invention,
- wherein that 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.
