Post Impact Stability Control Verifcation in driving simulator

Abstract

During the thesis an implementation and verifcation of the Post Impact Stability Control (PISC) function was done in a driving simulator. The aim of the function is to avoid, or at least mitigate, secondary collisions by minimising the lateral deviation of the vehicle after the initial impact in a multiple-event accident. The PISC function was developed and tested offline for debugging and tuning purposes as well as to serve as a guideline for the simulator tests. The results were as expected. The PISC function was also tested in the Chalmers S2 simulator in a study where four different tests were ran, where a set of unprepared test drivers were used in order to evaluate the benefits of the function and to analyse the reaction of the drivers and their interaction with the function. It was found that the PISC function is beneficial in most situations however a more sophisticated settling controller should be implemented to mitigate some of the undesired effects.
