SimbaV - Simulation-based test evaluation

A large amount of measurement data is recorded during crash tests for the objective assessment of vehicle safety components. Particularly in the case of prototype tests, which are usually very expensive, it is important to generate as much information as possible about the installed protection systems based on the recorded measurement data. The demands on the test technology are also constantly increasing in order to record new information that is important for the development engineers. Knowledge of the resulting dummy kinematics is also of great interest. At present, 3D film analysis is usually used to determine the precise dummy kinematics. However, this proven method requires that the body under consideration is visible from at least two cameras at all times. However, this requirement is generally not possible, as the dummy is partially obscured by various vehicle components (airbag, B-pillar, etc.) during the test. For this reason, the Institute for Vehicle Safety, in co-operation with two OEMs, has developed a new method which enables the calculation of precise trajectories of individual body parts from the fusion of sensor and video data. This process is being used successfully for development trials.
