Abstract
AbstractTo prevent four‐wheel independent drive electric vehicle (4WID EV) wheels from slipping when they are accelerating, an acceleration slip regulation (ASR) control strategy is proposed. Based on the classification of road conditions and the calculation of the optimal slip ratio for road conditions, the slip ratio is adjusted around the optimal slip ratio through controlling the driving torque output. Meanwhile, considering the change of wheel longitudinal force actually, we design a compensator in the ASR control strategy. Then, the system stability is analytically investigated through the classical control theory. Finally, we design an ASR control system in Matlab/Simulink, and apply the advanced simulation software Carsim to build a 4WID EV model, then build a cosimulation model using Carsim and Matlab/Simulink. The simulation results show the effectiveness and validation of the proposed ASR control strategy. © 2019 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
