The invention discloses a fault processing method for a hub motor distributed driving system. The method comprises the steps that whether each hub motor fails or not is judged; the torque T of a failure hub motor is adjusted, wherein the torque T of the failure hub motor is larger than 0 and smaller than the actual output torque of the failure hub motor; and the torque of each normal hub motor isadjusted according to the power performance requirement of a vehicle and the stability of the whole vehicle. The failure hub motor torque is controlled through the drive failure factor, on the premisethat the stability of the whole vehicle is maintained, the torque of other hub motors is controlled in combination with the intention of a driver to guarantee the dynamic property of the vehicle, andthe advantage that the distributed drive hub motor vehicle is independent and controllable is brought into play to the maximum extent; the problem that a four-hub motor driven vehicle is insufficientin dynamic property under a failure fault is effectively solved, and the safety and the working efficiency of emergency rescue work are improved.

    本发明公开了一种轮毂电机分布式驱动系统故障处理方法,判断每个轮毂电机是否失效;调整失效轮毂电机的转矩T,失效轮毂电机的转矩0<T<该失效轮毂电机实际输出转矩;根据车辆动力性能需求和整车稳定性调整每个正常轮毂电机的转矩。本发明利用驱动失效因子控制失效轮毂电机转矩,在维持整车稳定性的前提下,结合驾驶员意图,控制其他轮毂电机转矩保证车辆动力性,在最大程度上发挥分布式驱动轮毂电机车辆独立可控的优势,有效解决了失效故障下四轮毂电机驱动车辆动力性不足的问题,提高了抢险救援工作的安全性以及工作效率。
