The invention provides a vehicle deflection control method and device and a storage medium, a vehicle comprises a front side left wheel and a front side right wheel, and a first torque of the front side left wheel and a second torque of the front side right wheel are obtained; if the torque difference between the first torque and the second torque reaches a differential torque threshold value, first steering torque corresponding to the torque difference is determined; target torque expected by a driver and required for steering is obtained; according to the target torque and the first steering torque, the power-assisted torque actually executed by an electric power-assisted steering system of the vehicle is determined; and controlling a motor of the electric power steering system to respond to the power torque. A distributed driving system and an electric power steering system are subjected to fusion control, and when torque difference exists between two wheels on the front side of the vehicle, part of torque is compensated through the electric power steering system, so that vehicle deflection caused by the torque difference is overcome, and normal running of the vehicle and the vehicle is ensured.

    本说明书提供一种车辆偏转控制方法、设备及存储介质,车辆包括前侧左车轮与前侧右车轮,获取所述前侧左车轮的第一扭矩和所述前侧右车轮的第二扭矩;若所述第一扭矩与所述第二扭矩的扭矩差达到差扭阈值,确定所述扭矩差对应的第一转向力矩;获取驾驶员期待的转向所需的目标力矩;根据所述目标力矩与所述第一转向力矩,确定所述车辆的电动助力转向系统实际执行的助力力矩;控制所述电动助力转向系统的电动机响应所述助力力矩。也即将分布式驱动系统与电动助力转向系统融合控制,当车辆前侧两个车轮存在扭矩差时,通过电动助力转向系统补偿部分力矩,以克服扭矩差所引起的车辆偏转,确保车俩的正常行驶。
