Anti-skid fuzzy control of an electric vehicle

In this paper, a new anti-skid fuzzy control for an electric vehicle was introduced, which controlled the motor torque to keep the slip ratio around the best slip ratio. The direct measurement of slip ratio was not needed in this method, instead the relationship between the increment of motor torque and that of adheson force was used. The simulation results indicate that the control system has good performance on controlling the slip ratio, enhancing the acceleration ability of the Electric Vehicle and ensuring its lateral stability.
