Controlling recording of accident data recorder in motor vehicle by determining time interval for recording by evaluating video signal from sensor

摘要

The method involves detecting the surrounding area of a motor vehicle in the direction of travel using a video sensor. The video signal is supplied to the accident data recorder (10). The video signal is analyzed and evaluated in the accident data recorder in accordance with a predetermined model. The evaluation signal is used in a characteristic diagram to determine the time interval of the recording of the accident data recorder. The analysis of the video signal may be based on safety and diagnostics systems, such as carriageway detection, object detection or road sign detection. The characteristic diagram may also receive data such as an airbag signal, vehicle speed, braking signal, travelling direction signal, acceleration signal or engine status signal. An Independent claim is included for an accident data recorder.
