摘　　要：针对目前国内车用驱动电机性能的现状,分析了电机输出转矩误差对车辆直线行驶稳定性的影响。利用横摆角速度作为反馈变量,对直线行驶过程中的驱动转矩进行协调控制。对应用该控制策略的某车型在所开发的电动轮驱动试验车平台上进行了不同速度下的道路试验。结果表明,该转矩协调控制策略能够保证车辆直线行驶稳定性。In view of the current technical status of automotive driving motor in China, the effect of motor output torque error on straight line driving stability is discussed in detail in the article. In this article, yaw velocity is taken as a feedback variable to coordinate the driving torque during straight line driving. Road test was made to a vehicle model which adopts this control strategy on the newly developed electric wheel-driven vehicle platform under different speeds. The results show that the torque coordinated control strategy can ensure vehicle＇s straight line driving stability.
