Abstract
A system for recording collisions in motor vehicles. The system includes a control unit that is connected to ultrasound sensors that can be disposed on or in the vehicle and is connected to acceleration sensors that can be disposed in the vehicle. Accident events are detected by the control unit based on acceleration values that are above a limit. Also, events below this limit are recorded when an approach to or contact with a collision object is determined by the ultrasound sensors.

16. A system for recording collisions in a vehicle, comprising:
-
a plurality of ultrasound sensors arranged at least one of on and in the vehicle; at least one accelerometer arranged in the vehicle; and a control unit arranged in the vehicle, and connected to the plural ultrasound sensor and the at least one accelerometer. wherein accident events are detected by the control unit based at least in part on an acceleration value above a limiting value, and even events below the limiting value are recorded when the plural ultrasound sensors detect at least one of an approach to and contact with a collision object. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 31)

25. A method for operating a collision recording system in a vehicle, wherein the system has a control unit connected to a plurality of ultrasound sensors and at least one accelerometer, the method comprising:
-
detecting an acceleration value; comparing the detected acceleration value to an acceleration limiting value, wherein accident events are detected based on the acceleration value above the acceleration limiting value; and recording events below the acceleration limiting value when the plural ultrasound sensors indicate a contact. - View Dependent Claims (26, 27, 28, 29, 30, 32, 33)
