DYNAMIC CHARACTERISTICS OF A WHOLE WHEEL STEERING VEHICLE WITH YAW VELOCITY FEEDBACK REAR WHEEL STEERING

The whole wheel steering system is considered as a means of further improving vehicle characteristics. In this paper, authors have studied this system and proposed a whole wheel steering system using yaw velocity feedback rear wheel steering. In addition, the dynamic characteristics of the vehicle with this steering system were theoretically analyzed, and experiments were carried out to make sure of its validity. The results of the study showed that any vehicle with this control system could greatly improve: (1) tracking; (2) steering properties; and (3) response to an external disturbance.
