The invention provides a vehicle driving motor torque control method and device and a vehicle. The control method comprises the steps that a road surface image of a road where the vehicle is located in the driving process and vehicle driving parameters are obtained; in response to the fact that the road surface image is acquired, determining road surface type information corresponding to the road by using a preset road surface recognition model based on the road surface image; determining a torque limit value of a driving motor arranged in the vehicle based on the road surface type information and the vehicle driving parameters; and determining a target torque of the driving motor based on the torque limit value and a target torque coefficient correspondingly determined by the vehicle running parameters, and controlling the driving motor to output the target torque. By means of the method, the motor performance is fully exerted, tire slipping is actively restrained, the using efficiency of the vehicle driving motor performance is improved, and then the accuracy and stability of driving motor torque control are improved.

    本申请提供了一种车辆驱动电机扭矩的控制方法、装置及车辆,所述控制方法包括:获取车辆在行驶过程中所在道路的路面图像和车辆行驶参数;响应于所述路面图像被获取,基于所述路面图像,利用预设的路面识别模型确定所述道路对应的路面类型信息;基于所述路面类型信息和所述车辆行驶参数,确定设置于所述车辆中的驱动电机的扭矩限值;基于所述扭矩限值和由所述车辆行驶参数对应确定的目标扭矩系数,确定所述驱动电机的目标扭矩,并控制所述驱动电机输出该目标扭矩。通过上述方法,充分发挥电机性能并主动抑制轮胎打滑,提高了车辆驱动电机性能的使用效率,进而提高了驱动电机扭矩控制的准确性和稳定性。
