The invention relates to a motor torque control method, device, motor controller and system, and relates to the technical field of automobile power. The method comprises the steps that the motor torque control device obtains the motor torque, the motor rotating speed and the driving wheel rotating speed of the vehicle under the target working condition; and determining the wheel end load of the vehicle under the target working condition according to the motor torque, the motor rotating speed and the driving wheel rotating speed. Further, the motor torque control device receives the required torque sent by the vehicle control unit, and the required torque is determined based on the control parameters of the vehicle under the target working condition; and the required torque is adjusted according to the wheel end load, and then a motor of the vehicle is controlled to operate according to the adjusted required torque. Therefore, the motor is controlled to output reasonable torque, and abnormal shaking of the whole vehicle is avoided.

    本申请涉及一种电机扭矩控制方法、装置、电机控制器及系统,涉及汽车动力技术领域。该方法包括:电机扭矩控制装置获取车辆在目标工况下的电机扭矩、电机转速以及驱动轮转速;并根据电机扭矩、电机转速以及驱动轮转速,确定车辆在目标工况下的轮端负载。进一步的,电机扭矩控制装置接收整车控制器发送的需求扭矩,需求扭矩为基于车辆在目标工况下的控制参数确定;并根据轮端负载,对需求扭矩进行调整,进而根据调整后的需求扭矩控制车辆的电机运行。由此,实现控制电机输出合理的扭矩,避免整车出现异常抖动。
