摘　　要：相对于传统车辆,分布式驱动电动汽车自由度增多,从而稳定性下降,所以对其稳定性的研究尤为重要。文章以某分布式驱动电动汽车为对象,结合其各车轮驱动转矩可单独控制的特点,探究有效防止其侧翻的控制方法。根据车辆运动方程及车辆参数,使用Simulink建立了车辆动力学模型;针对分布式驱动电动汽车设计了基于车轮差动驱动的防侧翻控制策略,并选取典型车辆侧翻工况进行仿真实验。实验结果表明:所设计的差动驱动防侧翻策略能有效提高车辆防侧翻能力,其模糊自适应比例-积分-微分(PID)控制器能根据车辆实时运动情况给出动态指令,差动驱动控制方式则能根据控制器指令迅速有效地阻止车辆侧翻。Compared with traditional vehicles,the degree of freedom of distributed drive electric vehicles increases,and the stability decreases,so the research on its stability is particularly important.This paper takes a distributed drive electric vehicle as an object,and explores effective control methods to prevent rollover based on the characteristics of each wheel drive torque that can be individually controlled.According to the vehicle motion equation and vehicle parameters,the vehicle dynamics model is established using Simulink;A rollover prevention control strategy based on wheel differential drive is designed,and the typical vehicle rollover conditions are selected for simulation experiments.The experimental results show that the designed differential drive anti-rollover strategy can effectively improve the anti-rollover ability of the vehicle,its fuzzy adaptive proportionalintegral-derivative(PID)controller can give dynamic instructions according to the real-time motion of the vehicle,and the differential drive control mode can quickly and effectively prevent the vehicle from rollover according to the controller instructions.
