The invention relates to a motor torque compensation method and device, a vehicle, a medium and a product, and the method comprises the steps: obtaining the required torque and working temperature of a motor at the current moment; according to the working temperature of the motor at the current moment and a preset mapping relation, the torque corresponding to the working temperature is determined, and the preset mapping relation is the mapping relation between the temperature and the torque; and calculating the torque difference between the torque corresponding to the working temperature and the reference torque, and compensating the required torque of the motor at the current moment according to the torque difference to obtain the target torque of the motor. Therefore, the problems that the influence rule of the motor temperature on the torque is not considered in a motor torque compensation mode in the related technology, so that the torque control precision is reduced, the driving safety of a user is reduced, the energy utilization efficiency of the vehicle is reduced, and the energy consumption in the vehicle driving process is increased are solved.

    本发明涉及一种电机扭矩补偿方法、装置、车辆、介质及产品,其中,方法包括:获取当前时刻电机的需求扭矩和工作温度;根据当前时刻电机的工作温度和预设映射关系确定工作温度对应的扭矩,其中,预设映射关系为温度与扭矩的映射关系;计算工作温度对应的扭矩与参考扭矩的扭矩差值,根据扭矩差值补偿当前时刻电机的需求扭矩得到电机的目标扭矩。由此,解决了相关技术中的电机扭矩补偿方式通常存在没有考虑电机温度对扭矩的影响规律,从而降低了扭矩控制精度,降低了用户的行驶安全、降低了车辆的能源利用效率,增加了车辆行驶过程中的能耗等问题。
