The invention discloses a motor torque determination method and device, equipment and a storage medium, and belongs to the technical field of vehicles. The method comprises the steps of firstly determining a target working condition currently met by a target vehicle, then determining a second corresponding relation corresponding to the target working condition based on a first corresponding relation, then obtaining a current target temperature and a current target rotating speed of a motor, determining a target torque corresponding to the motor from the second corresponding relation, and controlling the torque of the motor based on the target torque. Since the temperature limit value in the second corresponding relation is smaller than the derated temperature, the target torque determined based on the second corresponding relation is smaller than the derated torque of the trigger generator, so that the situation that the temperature of the motor reaches the derated temperature, consequently, the torque fluctuation of the motor is too large can be avoided, the motor obtains continuous and smooth torque, and the service life of the motor is prolonged. Therefore, the driving experience of the whole vehicle is improved.

    本申请公开了一种电机扭矩确定方法、装置、设备及存储介质,属于车辆技术领域。该方法先确定目标车辆当前所满足的目标工况条件,然后基于第一对应关系,确定目标工况条件对应的第二对应关系,再获取电机当前的目标温度和目标转速,从第二对应关系中确定电机对应的目标扭矩,基于目标扭矩控制电机的扭矩。由于第二对应关系中的温度限值小于降额温度,因此,基于第二对应关系确定的目标扭矩小于触发电机降额的扭矩,这样可以避免电机温度达到降额温度,造成电机的扭矩波动性太大,使电机获得持续的平顺的扭矩,从而提高整车的驾驶体验。
