The embodiment of the invention discloses a torque distribution method and device for a multi-motor system, equipment and a medium. The method comprises the steps that the pedal opening degree and the current speed of a current vehicle are obtained, and the current required torque of the current vehicle is determined according to the pedal opening degree and the current speed; determining at least one candidate torque distribution mode matched with the current demand torque; for any candidate torque distribution mode, candidate torque distribution combinations of different motors in the candidate torque distribution mode are determined; determining motor output power corresponding to each candidate torque distribution combination in different candidate torque distribution modes; and according to the motor output power of different candidate torque distribution combinations, selecting a target torque distribution combination from the candidate torque distribution combinations. According to the scheme, the motor torque of the multi-motor system is reasonably distributed.

    本发明实施例公开了一种多电机系统的扭矩分配方法、装置、设备及介质。该方法包括:获取当前车辆的踏板开度和当前速度,并根据所述踏板开度和所述当前速度,确定所述当前车辆的当前需求扭矩;确定与所述当前需求扭矩,相匹配的至少一个候选扭矩分配模式;针对任一候选扭矩分配模式,确定该候选扭矩分配模式下不同电机的候选扭矩分配组合;确定不同候选扭矩分配模式下各候选扭矩分配组合相对应的电机输出功率;根据不同候选扭矩分配组合的电机输出功率,从各所述候选扭矩分配组合中,选取目标扭矩分配组合。上述方案,实现了对多电机系统进行电机扭矩的合理分配。
