A 4WS Control Strategy for Improving Race Car Performances

Design and implementation of an active control system to enhance the vehicle’s performances is of great interest for any vehicle type, but for race cars, if allowed by the rules, is of fundamental importance since the vehicle is working most of the time in limit conditions. This paper presents a control strategy for rear wheels steering with the aim of increasing the reactivity of the vehicle while entering the curve and of stabilizing the vehicle in full curve, thus allowing higher vehicle speeds.
