Abstract

in newly type-approved or newly registered vehicles. These are primarily warning systems that alert the driver to the occurrence of a hazardous situation as well as emergency functions that can temporarily actively intervene in the vehicle's driving dynamics. In addition to these installed ADAS, vehicle manufacturers also offer numerous ADAS as optional equipment. These are mainly comfort functions that take over the lateral and longitudinal control of the vehicle for a longer period and are thus intended to relieve the driver of his driving task. Despite the opportunities associated with the presence of ADAS in terms of road safety, not all traffic accidents can be fully prevented due to the laws of physics. If a traffic accident does occur, it is often the task of a forensic expert to clarify the circumstances of the accident completely and beyond doubt. Due to the influence of activated ADAS on the vehicle's driving dynamics and on the driver's behavior, this can have a significant impact on the results of the simulation calculations of the accident. Consequently, the ADAS-driver interactions that have taken place must be considered during forensic accident reconstruction. Since not all ADAS activities must be stored in the Event Data Recorder (EDR), there is often a lack of doubtlessly usable facts. Consequently, experimental analyses are the only remaining alternative. To be able to guarantee that the experimental results can be used in court, however, numerous potential factors influencing the behavior of the ADAS must be considered when conducting the experiments, and these were identified in the present work. As a result, it could be determined that the accident recording, and the detailed technical inspection of the vehicles are the essential fundamentals to generate reproducible, comprehensible, and thus court-proof test results. Due to the high sensitivity of the ADAS to small changes in the test setup and procedure, the limits of the tolerance bands of the reconstruction parameters should also always be considered during the tests and tested several times to be able to derive a statistical conclusion.
