The invention discloses a motor torque control method and device. The method comprises the following steps: acquiring the rotating speed of a motor; the working state of the motor is determined based on the rotating speed of the motor, and the working state comprises whether the motor is in a locked-rotor state or not; heat accumulation data, corresponding to the working state, of the motor are determined, and the heat accumulation data are used for representing the heating degree of the motor; the torque of the electric machine is derated based on the heat accumulation data. The technical problem that the control efficiency of the motor torque is low is solved.

    本发明公开了一种电机扭矩的控制方法和装置。其中,该方法包括:获取电机的转速;基于电机的转速确定电机的工作状态,其中,工作状态包括电机是否处于堵转状态;确定电机的与工作状态对应的热累积数据,其中,热累积数据用于表征电机的发热程度;基于热累积数据,对电机的扭矩进行降额。本发明解决了对电机扭矩的控制效率低的技术问题。
