SIMULATION OF AUTOMOBILE MOTION INCLUDING NON-STEADY-STATE SIDE SLIP PHENOMENON

Abstract

The aim of the article is to present the application of simple single-track planar model of automobile to investigate non-steady-state side slip. The so-called “bicycle” model can be used to simulate curvilinear motion of vehicle. It is successfully applied for the development of electronic stability program (ESP). In this work two different approaches to describe side slip phenomenon are shown. First one is based on simple linear dependence between lateral force acting on pneumatic wheel and side slip angle as a result of this interaction. However, this approach is proper for steady-state conditions of side slip, though usually in narrow range of side slip angle. In case of non-steady-state maneuvers such as slalom, double lane change, the dependence between lateral force and side slip angle should also include such parameter that would describe the dynamics of side slip phenomenon. In this article side slip angle derivative is used to represent the dynamics of side slip angle changes. Exemplary simulation results are presented using two different side slip phenomenon descriptions.
