The invention discloses a vehicle heating control method. The method comprises the steps that 1, torque, rotating speed, a motor mode, environment temperature and system operation meeting the torque mode are obtained, and a pre-motor efficiency reduction heating available mark is sent; 2, when the VCU receives the front motor efficiency reduction heating available mark, a front motor efficiency reduction heating request is sent to start efficiency reduction heating; 3, according to the rated voltage, the rotating speed and the torque of the motor, requesting the MCU to inquire the current meters of the d axis and the q axis, and outputting the inquired current of the d axis and the q axis; and step 4, the current motor works at the active heating power to perform active efficiency reduction heating. According to the invention, after calibration conditions of torque, rotating speed, motor mode and environment temperature are met, motor efficiency-reducing heating can be carried out, and energy consumption can be reduced.

    本发明公开了一种车辆加热控制方法,步骤1:中获取扭矩、转速、电机模式、环境温度,系统运行满足扭矩模式,发送前电机降效加热可用标志;步骤2:VCU收到前电机降效加热可用标志时,发送前电机降效发热请求启动降效加热;步骤3:根据电机的额定电压、转速及扭矩,请求MCU查询d轴和q轴的电流表,并将查询的d轴和q轴电流输出;步骤4:当前的电机工作以主动加热功率主动降效发热。本发明在满足扭矩、转速、电机模式、环境温度的标定条件后才可进入电机降效加热,以电机进行降效加热,有助于减低能耗。
