Simulation using a full dummy model enables to analyse the kinematics of the human body when impacted by a car's front end. So the parameters influencing the pedestrian's kinematics as well as the car's crash behaviour can be investigated and critical impact zones can be localized. Concerning the subsystem tests according to EEVC resp. ACEA a highly simplified model allows general determination of the influence different parameters have on the results for the prescribed test criteria (deceleration of tibia, knee bending angle and knee shear displacement) for the lower legform to bumper test. A parameter model offers the advantage of very easy and quick alteration of the model and a minimum of calculation time. So the influence of various parameters can be investigated in a fast and convenient way. Examination using a parameter model can be applied for first studies, in an early state of development when no concrete boundaries are given yet. Of course this examination enables to work out tendencies only, concrete values depend on the baseline conditions applied to the parameter model. Nonetheless, a parameter model provides an useful tool in discussion with other departments and allows to develop guidelines for future car design and construction.
