The invention provides a torque distribution method, a vehicle and a storage medium, and relates to the technical field of automobiles, the method comprises the following steps: determining the driving condition of the vehicle based on the driving data of the vehicle; if the driving working condition is the longitudinal economic working condition, the driver input torque, the average rotating speed of the multiple motors and the target rotating speed interval of each motor are determined, and the target rotating speed interval is the rotating speed interval where the kinetic energy conversion efficiency of the motors is larger than a first preset threshold value; based on the driver input torque, the average rotating speed of the multiple motors and the target rotating speed interval of each motor, the torque distribution proportion of front and rear shafts of the vehicle is determined; and performing torque distribution on the front and rear axles of the vehicle based on the torque distribution ratio of the front and rear axles of the vehicle. According to the scheme, torque distribution is carried out on the front shaft and the rear shaft of the vehicle on the basis of the driver input torque, the average rotating speed of the multiple motors and the kinetic energy conversion efficiency of each motor, so that the torque distribution mode better conforms to the longitudinal economic working condition, and the torque distribution accuracy is improved.
