摘　　要：针对纯电动商用车在载重变化、坡道变化等因素下存在转矩输出响应滞后、操控性能下降的问题,提出了一种基于转矩补偿的整车控制方法。该方法结合了模糊控制算法和转矩补偿策略,通过Simulink搭建整车控制器模型,将模型进行代码生成并刷写进控制器,同时使用CANoe和vTESTstudio搭建测试系统,对模型进行硬件在环测试。结果表明,基于转矩补偿算法的控制器显著提升了商用车根据驾驶员意图以及实时车况变化时的加速性能,提升了车辆的操纵性能。A vehicle control method based on torque compensation was proposed to solve the problems of response lag of torque output and deterioration of control performance of pure electric commercial vehicles under the influence of load changes,ramp changes,and other factors.The method combined the fuzzy control algorithm and the torque compensation strategy.The vehicle controller model was built through Simulink,and the model code was generated and written into the controller.At the same time,the test system was built using CANoe and vTESTstudio to perform hardware-in-the-loop testing on the model.The results show that the controller based on the torque compensation algorithm significantly improves the acceleration performance of commercial vehicles according to the driver’s intention and real-time changes in vehicle conditions and enhances the vehicle’s control performance.
