This thesis project focuses on the verification method of a safety function called PIC that stands for Post-Impact Control which controls the vehicle motion of passenger cars after being exposed to external disturbances produced by a 1st impact, aiming at avoiding or mitigating secondary events. The main objective was to select a promising method, among several candidates, to develop further for testing the function and the interaction with the driver. To do this is was first necessary to map the real destabilized states of motion that are targeted by the function. These states are referred as Post-Impact problem space and are a combination of variables that describes the host vehicles motion at the instant the destabilizing force has ceased. Knowing which states are requested by the solution candidates, it is possible to grade the rig candidates based on the capability of covering the problem space. Then, simulating the proposed rig solutions with Matlab/Simulink models to investigate which candidate fulfils best the problem space. The result of the simulations and other criteria is that a moving base simulator (Simulator SIM4) is most fitted to research verification. The second most advantageous solution is the rig alternative called Built-in Actuators.
