The embodiment of the invention provides a vehicle motor torque control method and device, equipment and a medium. By responding to gear shifting operation of a vehicle, a mark signal corresponding to the gear shifting operation is generated; then acquiring the driving state information of the vehicle, and smoothing the torque of the rear motor of the vehicle according to the driving state information and the sign signal; and obtaining the required torque of the whole vehicle, and carrying out torque distribution on a front motor and a rear motor of the vehicle according to the required torque of the whole vehicle and the first torque distribution logic during the period of carrying out smoothing processing on the torque of the rear motor of the vehicle. The smoothness during torque gradient processing is further improved in a torque distribution mode on the basis of torque gradient smoothing processing, the stability of a vehicle in the gear shifting process and even in the starting process after gear shifting is improved, and the impact phenomenon occurring when a brake is slightly stepped on and creep torque exists is avoided; and the overall driving experience and the vehicle power performance are improved.

    本发明实施例提供了一种车辆电机扭矩的控制方法及装置、设备、介质,通过响应于车辆的换挡操作,生成与换挡操作相对应的标志信号;随后获取车辆的行驶状态信息,并根据行驶状态信息与标志信号,对车辆的后电机扭矩进行平滑处理;进而获取车辆的整车需求扭矩,并在对车辆的后电机扭矩进行平滑处理期间根据整车需求扭矩与第一扭矩分配逻辑对车辆的前电机与后电机进行扭矩分配的方式,实现了在对扭矩梯度平滑处理的基础上进一步通过扭矩分配的方式增加扭矩梯度处理时的平滑性,提高了车辆在换挡过程中乃至换挡后起步时的平稳性,避免了当轻踩刹车并存在蠕行扭矩时出现的冲击现象,提升了整体驾驶体验和车辆动力性能。
