This paper deals with the pre- and post-impact motion of vehicles. In general, vehicles incline their chassis due to the variation of wheel loads during motion. The authors have already suggested the analytical method for the motion of four-wheel vehicles in which the wheel loads were solved as unknown values. However, the inclination of chassis was not considered in the previous paper. When the chassis is inclined, the moments about the vehicle center of gravity vary because the projective distances between the center of gravity and the wheel contact points to road surface change. Therefore, we take the inclination of chassis into consideration in this paper. Since the equations of motion of the vehicle become nonlinear with respect to the wheel loads, they are solved iteratively under influence of inclination of chassis at each time step of calculation.
