Abstract
This paper is about a fixed step size time-stepping scheme for the computation of solutions of complementarity problems. As we want to optimise chassis dynamics by solving optimal control problems, we took a closer look at modeling contact conditions. The latter are important, as the contact force is directly related to handling caracteristics of the automobile. This plays an important role particularly in certain driving situations, e.g. driving over a pothole. Hereafter the motivation for the development is carried out and the components of the scheme are explained. At the end we compare the calculation of a quartercar with a spring-damper road to wheel interaction to those resulting from the complementarity problem.
