Task 1.3 of PENDANT Work Package 1 has numerous objectives. In a first step statistical analysis has to be performed to compare the casualty of single vehicle accidents of cars with and without Electronic Stability Programme (ESP), (or other safety feature, as agreed with the EC depending on data availability). In a WP 1 meeting it was decided to use ESP for this purpose. Most of the cars are already equipped with ABS and another investigation to this active safety feature didn’t sound reasonable. In a second step the most well documented 30 (if available) single car accidents with cars not equipped with ESP should be identified. Those accidents were additionally investigated and reconstructed. In comparison each case should be simulated with the assumption that the cars are equipped with ESP. The differences regarding accident avoidance or severity as well as reduction of injury risk will be investigated and the effectiveness will be documented. An additional part for this analysis was the possibility that ESP could prevent accidents. Of course not every situation can be handled. In the end 26 cases were available for analysis. Another important issue is the influence of engineering countermeasures. Therefore a general simplified multi-body car model for the collision phase will be used to predict acceleration, deformation and intrusion behaviour of the cars during a real world accident. The possibility of adapting this multi-body model to specific car makes and models will be explored. The validation of these models will be based on the crash test database developed in task 1. The simulation results of this new tool can than be used as input for occupant simulation to predict injuries or the effect of engineering countermeasures on the injury risk of the occupants. Partners of this task were VSRC, VW, TNO and TUG and within those four parties the work were spread. (Author/publisher)
