Summary:

The potential of determining the change of injury severity inthe accident event taking passive as well as active measures intoaccount at the vehicle (integral systems) are at present limited topedestrian protective systems. Therefore, an extension of theexisting methods for the application with common integral systems(front protection, side protection, et cetera) is suggested. Nowadaysthe effectiveness of passive safety systems is determined in crashtests with very high accident severities. However, approximately90% of real-world accidents have a lower accident severity as therequired crash tests. Thus, this paper will present a methodcalculating the effectiveness of such an integral system based onreal-world accident data. For these reasons, this paper ispresenting a method for a more valid prediction of injuryseverity.The German In-Depth Database GIDAS allows clustering theaccident event in relevant car-to-car scenarios. The vehicledynamics of all scenarios from the database will be simulated inPC-Crash, an accident-reconstruction software. Since the brakeassist is obligatory from 2012 on, the system and its effect oneach single accident scenario will be modeled. The effect of therestraint system will be calculated with Finite Element SimulationPAM-Crash. The outcome of the occupant simulation, the FMVSS injurycriteria (e.g., HIC₃₆), will be converted into the risk factor tosuffer an AIS3+ injury for each body region. Finally, the sum ofall the injury risks weighted with the relevance of each scenariodetermines the expected value of MAIS3+ injured persons.Consequently, the percentage of protected MAIS3+ occupants can becalculated and the real-world benefit of an integral safety systemcan be evaluated.The method described above covers all requirements forcalculating the effectiveness of an integral safety system.Therefore, systems influencing vehicle dynamics will be modeled.The effect of these systems on impact situation will be calculatedand implemented in the occupant simulation. In combination, by theuse of this method the effectiveness of an integral safety systemis determined
