Stability Analysis of Automatic Lateral Motion Controlled Vehicle with Four Wheel Steering System

The inherent dynamics of a vehicle are important factors in automatic vehicle control systems. This paper discusses the stability of an automatic lateral motion controlled vehicle equipped with a four wheel steering system focusing in particular on the vehicle dynamics. The four wheel steering system is configured around a model following control theory. The results of a stability analysis and simulations are presented to show that the four wheel steering system is effective in increasing the stability and performance of an automatic lateral motion controlled vehicle.
