摘要：

Proposed in this paper is an ASR (Acceleration Slip Regulation) control method based on the fuzzy road identification for 4WID (Four-Wheel Independent Drive) electric vehicles. In this method, low road adhesion coefficient and slip rate are both estimated higher with fuzzy rules to quickly and accurately identify the road with low adhesion coefficient, and, according to the independent controllability of the drive torque as well as the accessibility of the rotational speed and torque of each wheel, both the road adhesion coefficient and the optimal slip rate are estimated in real time. Thus, the drive torque of each wheel is effectively controlled and the ASR is successfully implemented. Simulation results indicate that the proposed ASR control method helps to quickly and accurately identify the road with low adhesion coefficient, avoid the slip of the driving wheel, and improve the driving stability and power performance of vehicles.
