Subsequently the impact model was analyzed for its sensitivity to specific input parameters. Real accidents were re-simulated using pre-defined input parameters for the impact model (virtual forward simulation – VFS). In this study a momentum based impact model is assessed in terms of reliability to solve the collision mechanics and therefore to predict delta-v for frontal car collisions. In order to assess the effects on injury severity developing methods, that are able to predict collision parameters correlating with the risk of getting injured, such as delta-v, for different impact situations is a mandatory task. Up to now the assessment is mostly based on the decrease of the collision speed due to CMS (collision mitigation systems). ![]() ![]() The advent of active safety systems calls for the development of appropriate testing methods that are able to assess their capabilities to avoid accidents or lower impact speeds and thus, to mitigate the injury severity.
