The invention relates to a temperature adjusting method for a vehicle-mounted component, which comprises the following steps that in response to a temperature adjusting request signal of the vehicle-mounted component, decoupling of a first driving motor and a first gear box with a half shaft of a vehicle is executed, and the first driving motor is coupled with the first gear box; determining a target rotating speed omega t of the first driving motor based on the obtained actual temperature Tr and target temperature Tt of the vehicle-mounted part; the rotating speed omega of the first driving motor is controlled at least based on the target rotating speed omega t of the first driving motor, when the rotating speed omega is smaller than or equal to a preset rotating speed threshold value, heat energy generated through a first gear box is adjusted by controlling the rotating speed omega of the first driving motor, and when the rotating speed omega is larger than the preset rotating speed threshold value, heat energy generated through a second gear box is adjusted. The thermal energy generated by the first drive motor is adjusted by controlling the stator current component Id of the first drive motor in the rotor magnetic field direction. According to the application, the temperature of the vehicle part is efficiently adjusted, and the energy utilization rate and the endurance mileage of the electric vehicle are improved.

    本申请涉及一种用于车载部件的温度调节方法,其包括以下步骤:响应于车载部件的温度调节请求信号,执行第一驱动电机连同第一齿轮箱与车辆的半轴的解耦,第一驱动电机与第一齿轮箱耦合;基于所述车载部件的获取的实际温度Tr和目标温度Tt确定所述第一驱动电机的目标转速ωt;至少基于所述第一驱动电机的目标转速ωt控制第一驱动电机的转速ω,在转速ω小于等于预设转速阈值时,通过控制第一驱动电机的转速ω调节通过第一齿轮箱产生的热能,在转速ω大于预设转速阈值时,通过控制第一驱动电机沿转子磁场方向的定子电流分量Id调节通过第一驱动电机产生的热能。根据本申请,实现对车辆部件高效地进行温度调节,并提高电动车辆的能源利用率和续航里程。
