The invention provides a method for starting an engine of a parallel oil-electricity hybrid power vehicle model, which comprises the following steps of: starting a key T50, judging a high-voltage power-on permission condition, and controlling a power battery BMS (Battery Management System) to be powered on; after the high-voltage power-on system is completed and the driving motor is in a ready state, the HCU controls the rotating speed of the driving motor to be a set value through a rotating speed control mode, and meanwhile, the clutch is controlled to be combined; and after the clutch is combined, the driving motor drives the engine and the driving motor to coaxially rotate through the intermediate shaft, and engine starting is completed after it is judged that the rotating speed of the engine reaches a set value and is stable. The purpose of rapidly and successfully starting the vehicle can be achieved by controlling the rotating speed of the motor to drive the engine to start. According to the method, the mode that the engine is controlled to be started at the proper rotating speed is adopted, uncertain values caused by external factors can be avoided, the engine can be rapidly and stably started, and the situation that a vehicle shakes during starting is avoided.

    本发明提供了一种并联油电混合动力车型启动发动机的方法,包括钥匙T50启动,判断高压允许上电条件,控制动力电池BMS系统上电;当高压上电系统完成且驱动电机处于准备就绪状态后,整车控制单元HCU通过转速控制模式控制驱动电机的转速在设定值,同时控制离合器结合;当离合器结合后,驱动电机通过中间轴带动发动机与驱动电机同轴转动,判断发动机的转速达到设定值且稳定后,发动机启动完成。本发明通过控制电机转速来带动发动机启动可达到快速成功启动车辆的目的。本发明采用合适转速控制启动发动机的方式既可以既可以不受外界因素引起的值不确定,又可以快速平稳的启动发动机,避免启动时车辆抖动的情况。
