摘　　要：针对汽车直接横摆力矩控制,基于Car Sim中已有的车辆模型参数,应用MATLAB/Simulink设计建立了四轮轮毂电机模型和电子稳定程序(ESP)的横摆力矩决策模糊PI控制器。分别在变车速双移线试验和变车速蛇形试验工况,通过Car Sim与MATLAB/Simulink联合仿真进行ESP控制策略仿真试验验证,并对采集到的数据进行分析。仿真试验结果证明,该控制方法能够使汽车很好地控制汽车行驶操纵的稳定性,验证了算法的可行性和有效性。Focused on vehiele direct yaw moment control, based on the parameters of existing vehicle model in CarSim, four wheel hub motor model and electronic stability program （ESP） yaw moment fuzzy decision PI controller were designed osing MATLAB/Simulink. ESP control strategy was verified through CarSim and MATLAB/Simulink co-simulation in variable speed double lane change test and pylon course slalom test, and the data acquired from the tests are analyzed. The resuhs show that the control method can make the ear has a good performanee of the vehicle running stability, and can verify the feasibility and effectiveness of the algorithm.
