摘　　要：设计了基于横摆角速度与质心侧偏角的联合滑模变结构控制策略,基于Car Sim和MATLAB软件建立了电动轮汽车整车模型和整车控制模型,对电动轮汽车的驱动DYC系统进行了仿真分析。结果表明,设计的联合滑模变结构控制器具有良好的鲁棒性,能较好地控制车辆的横摆角速度和质心侧偏角;所采用的轴载比例分配算法对车辆的纵向加速度影响较小,既实现了车辆横向稳定性的控制,同时提高了车辆的舒适性。In this research, a joint sliding mode variable structure control strategy based on yaw rate and center-of- mass side-slip is designed, and the vehicle model and the vehicle control model of the electric wheeled vehicle are established based on CarSim and MATLAB, and driving DYC of the electric vehicle is simulated and analyzed. The results showed that the designed joint sliding mode variable structure controller has good robustness and can achieve good control of vehicle yaw rate and the center-of-mass angle. The axle load distribution algorithm applied has less influence on vehicle longitudinal acceleration, which not only achieves vehicle lateral stability control, but also improves driving comfort.
