The invention discloses a traction control method for a four-wheel independent drive electric automobile under an extreme working condition, which comprehensively considers the control requirement ofa driver and the stability principle of the vehicle, adopts three different drive modes to replace a single torque distribution mode, and utilizes the longitudinal and lateral attachment margins of tires to the maximum extent. The motion tracking precision and the automobile body stability requirement of the four-wheel independent drive electric vehicle on a low-adhesion road surface are guaranteed; meanwhile, an upper-layer control target and a bottom-layer execution result are kept consistent, a driver can conveniently control the vehicle under the limit working condition, and the active safety of the automobile is improved.

    本发明公开一种极限工况下的四轮独立驱动电动汽车牵引力控制方法,综合考虑了驾驶员的控制需求以及车辆的稳定性原则,采用三种不同的驱动模式取代了单一的转矩分配方式,最大程度地利用了轮胎的纵、侧向附着裕度,保证了四轮独立驱动电动汽车在低附着路面的运动跟踪精度和车身稳定要求,同时也使得上层控制目标和底层执行结果保持一致,方便了驾驶员在极限工况对车辆的操纵,提高了车辆的主动安全性。
