Summary

This chapter places an emphasis on the physical meaning of the vehicle dynamics. It covers the dynamic modeling of the vehicle/tire system and describes tire/road interactions. The chapter discusses tire forces/moments and consequently semi-empirical tire models. The quasi-static Pacejka’s Magic tire formula, Dugoff’s model and the linear model representing the tire behavior are presented and compared. Dugoff’s tire model is not as accurate as the Magic formula, but it has the advantage of synthesizing the main tire properties into two parameters. The linear tire model is the simplest, but it overestimates the tire forces when the tire slip is significant and tire nonlinear zone is reached. The transient behavior of the tire is presented according to a relaxation tire model. Longitudinal and lateral tire-road friction are also interpreted. Next, vehicle body dynamics are considered. Vertical, longitudinal, lateral and roll motions are modeled.
