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.
