The invention provides a wheel end torque control method and system of a vehicle, a storage medium and the vehicle, and belongs to the technical field of vehicles, and the wheel end torque control method of the vehicle comprises the steps that the required wheel end torque distribution coefficient of a first drive axle is determined based on working condition parameters; determining a limit value range of a required wheel end torque distribution coefficient based on the total wheel end required torque and the maximum limit values of the respective wheel end torques of the first drive axle and the second drive axle; adjusting a required wheel end torque distribution coefficient based on the limit value range to obtain a target wheel end torque distribution coefficient of the first drive axle; and controlling the wheel end torque output by the first drive axle and the second drive axle based on the target wheel end torque distribution coefficient of the first drive axle. According to the method, effective torque distribution is performed on the first drive axle and the second drive axle through the target wheel end torque distribution coefficient of the first drive axle, and a reliable scheme is provided for wheel end torque distribution of the four-wheel-drive vehicle.
