The invention provides a control method for a parallel hybrid power starting engine, which comprises the following steps that: a vehicle control unit (HCU) judges the current condition of allowing high voltage to be supplied, and controls high voltage power-on enabling; after receiving an enable signal sent by the HCU, the driving motor can receive the rotating speed and torque control state of the HCU at any time, and when the voltage of the driving motor reaches a certain threshold range of the voltage of a power battery and an acceptable driving state is fed back, high-voltage power-on is completed, and a high-voltage system is ready. After a vehicle control unit controls a clutch connected between a driving motor and an engine to be closed, the engine and the driving motor are coaxial, the driving motor is controlled to drive the engine to coaxially rotate at a certain rotating speed, the current rotating speed of the engine reaches a certain threshold value and is stable within a period of time, and the rotating speed of the engine is still kept in an idling state. The engine is started successfully.

    本发明提出一种并联混合动力启动发动机的控制方法,整车控制单元判断当前允许上高压的条件,整车控制单元HCU控制高压上电使能;驱动电机在接收到HCU发送的使能信号后,可随时接收整车控制单元HCU转速与扭矩控制状态,当驱动电机电压达到动力电池电压一定阈值范围内时,且反馈可接受驱动状态时,高压上电完成,高压系统就绪。整车控制单元控制连接驱动电机和发动机的之间的离合器闭合后,发动机与驱动电机同轴,控制驱动电机一定转速下,带动发动机同轴转动,发动机当前转速达到一定阈值内并在一段时间内稳定,发动机转速仍继续保持在怠速状态,发动机启动成功。
