【Abstract】 A sliding mode based optimizer and traction control system which is used for a traction control system of in-wheel driven EV is developed in this paper. The basic idea of the proposed scheme can perform an on-line search for the optimal wheel slip that corresponds to the vehicle’s maximum acceleration. Thus, the robustness and adaptability of traction control systems are improved. The numerical results validate the proposed model and method.更多还原
