Modeling and simulation of fuzzy control to traction control system of the four-wheel-drive vehicle

A mathematical model of the acceleration process of four-wheel-drive vehicle was established and a Traction Control System (TCS) which takes driving slip ratio as the control object was realized with fuzzy control method. The fuzzy controller was designed with Fuzzy Logic Toolbox of MATLAB, and dynamic simulation has been carried out with SIMULINK. The result showed that TCS based on fuzzy control could control driving slip round the optimal value, improve the performance of traction and kinetics effectively, and prevent driving wheel from excessive spinning.
