Accident data recorder with a standstill memory for providing a data set for accident reconstruction

摘要

In order also to accidents, which are difficult to detect with a conventional accident data memory to provide a belonging to a certain measurement time period data set for accident reconstruction, wherein the data set from a time clock is continuously sensorially detected motion data and status data of various vehicle assemblies of that vehicle in which the accident data memory is, it is proposed to extend the accident data memory at a standstill memory and to fix the measurement time period for the registration of accident-relevant data set temporally characterized in that the control unit of the accident data memory then causes the registration if simultaneously the following criteria are met: a) with a certain arranged in the vehicle pulse vehicle speed has the value zero for at least two seconds; b) decreased the changes in amount of two at a time interval .DELTA.t successive measured values ​​for the longitudinal and lateral acceleration of the vehicle for at least two seconds under a predetermined value a; c) since the last triggered according to these criteria data set registration, the vehicle has moved by at least 100 meters.
