The Concept of Performance-Oriented Yaw-Control Systems: Vehicle Model and Analysis

In the last few years, extended research has been performed by car manufacturers in order to improve the handling, safety and comfort of ground vehicles. As a results, modern cars are equipped with many electronic automatic control devices. Among them the yaw-control system is probably the most critical and challenging. Road vehicles are complex non-linear dynamic systems, and the control of some of their motions needs the development of adequate full-vehicle models. In this paper a complete dynamic model of a road vehicle is derived and discussed, which can be suitably used to develop the new concept of “performance-oriented” yaw-control system.
