The invention relates to the field of motors, and provides a motor control method, a vehicle control method and a temperature control system.The method comprises the following steps that target output parameters of a motor are obtained; determining an initial magnetic field component current according to the target output parameter; acquiring magnetic field component current increment; determining a target magnetic field component current according to the magnetic field component current increment and the initial magnetic field component current; determining a target torque component current according to the target magnetic field component current and the target output parameter; and controlling the motor to operate with the target magnetic field component current and the target torque component current. According to the scheme, heating of the motor can be improved under the condition that the target output parameters of the motor are maintained, then heat generated by the motor can be conveyed to the power battery through the cooling liquid flow channel to heat the power battery, and therefore battery heating is achieved when the vehicle runs, additional PTC equipment does not need to be added, cost is saved, and the service life of the vehicle is prolonged. And direct current control on the battery is not needed, so that the battery is prevented from being damaged.

    本发明涉及电机领域,提出一种电机控制方法、车辆控制方法及温控系统,包括如下步骤,获取电机的目标输出参数;根据所述目标输出参数确定初始磁场分量电流;获取磁场分量电流增量;根据所述磁场分量电流增量和所述初始磁场分量电流确定目标磁场分量电流;根据所述目标磁场分量电流和所述目标输出参数确定目标转矩分量电流;控制所述电机以所述目标磁场分量电流和所述目标转矩分量电流运行。上述方案中可以在维持电机目标输出参数的情况下提升电机发热,然后可以通过冷却液流道将电机产生的热量输送至动力电池处对动力电池进行加热,从而实现车辆行驶时的电池加热,无需增加额外的PTC设备节约成本,且无需对电池进行直接的电流控制,避免电池损坏。
