This paper first describes a joint development project between Mannesmann Kienzle GmbH and VOLVO Car Corporation regarding an advanced Crash Recorder (CR) to be installed in the vehicle test fleet by VOLVO. The objective of the project is mainly to gain experience concerning the correlation between crash severity, vehicle damage and bodily injuries of the occupants by getting access to extensive and accurate in-vehicle data from real life accidents. The Crash Recorder monitors and records a number of variables during the phases of pre-impact, impact and post-impact. Parallel to this device a low-cost consumer's device has been developed by Mannesmann Kienzle and the full concept of this device will be presented. The objective of this low-cost Accident Data Recorder (ADR) is to provide a qualified in-vehicle monitoring system providing vehicle trajectories data for direct use in computeraided accident reconstruction. The result of the specific accident reconstruction can be used for settling liabilities of driver and/or product or for aggregating data in the society's traffic research activities.
