Abstract :
This paper examines the feasibility of proposed control for independent four-wheel drive electric vehicle. According to vehicle longitudinal velocity and the tire-road condition, a new method to determine the target value, i.e., vehicle yaw rate and side slip angle, is presented. The effectiveness of the designed controller based on sliding mode control is investigated by simulations using a seven-degree-of-freedom dynamic model with a unified non-linear and non-steady tire model. The simulation results indicate a satisfactory handling performance through an external yaw moment which is achieved by sliding mode control strategy.
