The invention discloses a motor torque determination method and device, a vehicle and a storage medium. The method comprises the steps that a torque request source in a current period is determined; determining a target torque request source of the current period in the torque request sources, wherein the target torque request source is the torque request source with the highest priority in the torque request sources; determining a target torque value of the current period according to the target torque request source; according to the target torque value and the number of execution motors working normally in the vehicle, the output torque value of each execution motor working normally in the current period is determined; and controlling each execution motor which works normally to output a corresponding output torque value in the current period. According to the motor torque determination method provided by the invention, the implementation complexity of independently considering the torque limit value corresponding to each torque request source is reduced, the multi-channel full-redundancy control of the torque value is realized, and the safety of the whole vehicle is improved by fully utilizing the capability provided by a hardware mechanism of the whole vehicle.

    本发明公开一种电机扭矩的确定方法、装置、车辆及存储介质,包括:确定当前周期内的扭矩请求源;在扭矩请求源中确定当前周期的目标扭矩请求源,目标扭矩请求源为扭矩请求源中优先级最高的扭矩请求源;根据目标扭矩请求源确定当前周期的目标扭矩值;根据目标扭矩值和车辆中正常工作的执行电机的数量,确定各个正常工作的执行电机在当前周期内的输出扭矩值;控制各个正常工作的执行电机在当前周期内输出对应的输出扭矩值。本发明提供的电机扭矩的确定方法,降低了独立考虑各个扭矩请求源对应的扭矩限值实现的复杂性,实现了扭矩值的多通道全冗余控制,充分的利用整车的硬件机构提供的能力提高整车的安全性。
