Anti-skid for Electric Vehicles based on sliding mode control with novel structure

It is prone to skid or slip for wheel vehicles when driving on the low adherent surfaces. Due to the high nonlinearity of time-varying parameters and uncertainties, the anti-skid control is usually very difficult. A robust anti-skid control based on the sliding mode control and friction coefficient estimation is proposed. Furthermore, a novel anti-skid control structure utilizing the driver's demanded slip ratio is adopted to coordinate the automatic control and the man's operation on foot pedal. Co-simulations with SIMULINK and CarSim show the effectiveness.
