The invention provides a torque distribution method and device, a storage medium and a vehicle, and belongs to the technical field of vehicles. According to the embodiment of the invention, under the condition that the current whole vehicle motor efficiency is smaller than an efficiency threshold value, a reference motor and an adjusting motor are determined in a front axle motor and a rear axle motor; the reference torque of the reference motor and the whole vehicle demand torque of the vehicle are determined, the target torque of the adjusting motor can be determined based on the whole vehicle demand torque and the reference torque, and then the reference motor is controlled to output the torque according to the reference torque under the condition that the reference torque and the target torque meet the torque adjusting condition. And controlling the adjusting motor to output the torque according to the target torque. According to the embodiment, when it is detected that the efficiency of the motor of the whole vehicle is low, the whole vehicle can run in an efficient interval through torque cooperation between the reference motor and the adjusting motor, and therefore the comprehensive efficiency of the motor is effectively improved while the vehicle driving requirement is met.

    本申请提供了一种扭矩分配方法、装置、存储介质和车辆,属于车辆技术领域,本申请实施例通过在当前整车电机效率小于效率阈值的情况下,在前桥电机和后桥电机中确定基准电机和调节电机,并确定基准电机的基准扭矩以及车辆的整车需求扭矩,能够基于整车需求扭矩和基准扭矩,确定调节电机的目标扭矩,进而在基准扭矩和目标扭矩满足扭矩调节条件的情况下,控制基准电机按照基准扭矩输出扭矩,并控制调节电机按照目标扭矩输出扭矩。本申请实施例能够在检测到整车电机效率较低时,通过基准电机和调节电机之间的扭矩配合,使得整车能够运行在高效区间,进而在满足车辆驱动需求的同时,有效提升电机的综合效率。
