Benefits of technology

The invention proposes a sensor device that can detect contact events on a vehicle by measuring impact sound. The device is easy to assemble and can be retrofitted into an existing vehicle. The sensor device utilizes already existing wiring, reducing labor costs. It can be connected to existing ultrasound distance sensors and can detect contact events across the entire outer shell of the vehicle. The device is cost-effective and can be easily installed. The vehicle can also have a sensor device in the area of ultrasound distance sensors for parking assistance. This invention allows for efficient and cost-effective monitoring of contact events without increasing assembly costs.

Problems solved by technology

The wiring of impact sound sensors, especially in the outer areas of the vehicle outer shell, is very cumbersome, so that it is favourable to utilise already existing wiring.

Embodiment Construction

[0023]FIG. 1 shows an impact sound sensor 1 arranged between the outer shell 2 of a motor vehicle and the mounting part 3 of an ultrasound distance sensor 4. The ultrasound distance sensor 4 is arranged on a housing part 5 and comprises a signal processing means 6, a piezo element 7 and a membrane 8 in the outer contour of the outer shell of the vehicle. The ultrasound distance sensor 4 together with its housing 5 is retained by the mounting part 3 on the inside of the outer shell 2 of the motor vehicle. The impact sound sensor 1 is arranged between the mounting part 3 and the inside of the outer shell 2. Therefore, an electrical contact (e.g., electrical contact 18) is established between the impact sound sensor 1 and the ultrasound distance sensor 4. The impact sound sensor 1 may for example be configured as a piezo-electric foil, which is self-adhesive on both sides so that the mounting part 3 is retained on the outer shell 2 by the piezo-electric foil. It is also possible for th...

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.
