The embodiment of the invention provides a vehicle torque control method and device, electronic equipment and a storage medium. The method comprises the steps that the wheel speed of a wheel corresponding to a vehicle driving shaft is obtained, and the equivalent rotating speed of a motor is calculated according to the wheel speed of the wheel; obtaining the actual rotating speed of the motor corresponding to the driving shaft, and calculating the equivalent rotating speed difference of the motor of the driving shaft where the wheel is located according to the equivalent rotating speed of the motor and the actual rotating speed of the motor corresponding to the driving shaft; obtaining a corrected torque value according to the equivalent rotating speed difference of the motor of the driving shaft where the wheels are located; adjusting the output torque of a motor corresponding to the driving shaft according to the corrected torque value. The equivalent rotating speed difference of the shaft where the wheel is located can be calculated according to the wheel speed of the wheel and the rotating speed of the driving shaft, whether the shaft where the wheel is located needs torque reduction or not is judged according to the equivalent rotating speed difference, the difficulty of calculating the slip rate is reduced, torque can be transferred from the low-attachment end to the high-attachment end according to the state of the single wheel and the state of the single shaft, and the torque reduction efficiency is improved. And the attachment utilization rate of the whole vehicle is improved, so that the power performance is improved.

    本发明实施例提供了一种车辆扭矩控制方法、装置、电子设备以及存储介质,该方法包括:获取车辆驱动轴对应的车轮的轮速,根据车轮的轮速计算电机等效转速;获取驱动轴对应电机的实际转速,根据电机的等效转速、驱动轴对应电机的实际转速,计算车轮所在驱动轴的电机的等效转速差;根据车轮所在驱动轴的电机的等效转速差,获取修正扭矩值;根据修正扭矩值调整驱动轴对应电机的输出扭矩。本发明可以通过车轮的轮速和驱动轴的转速,计算出车轮所在轴的等效转速差,根据等效转速差判断车轮所在的轴是否需要降扭,降低了计算滑移率的难度,可以根据单轮的状态和单轴的状态,将扭矩从附着低的一端转移至附着高的一端,提高了整车的附着利用率从而提升了动力性能。
