The invention relates to an engine starting control method and device, a medium, a vehicle control unit and a vehicle. In the hybrid vehicle, one end of a driving motor is connected with an engine through a clutch, the other end of the driving motor is in transmission connection with wheels, and the method comprises the steps that the output torque of the driving motor and the joint state of the clutch are obtained; and when the clutch is in the open state and the output torque of the driving motor is smaller than the driving demand torque, the driving motor is controlled to start the engine through the clutch. Therefore, the engine can be started through the motor system, a 12V starter system, a 12VBSG system or a high-voltage BSG system does not need to be additionally carried on the hybrid power vehicle, and the cost of the whole vehicle is reduced. The motor system is a high-voltage system, the starting power is high, and the rotating speed of the engine can be dragged to a high rotating speed, so that the engine can be quickly started. In addition, in the running process, the driving motor can independently provide running driving force for the hybrid power vehicle and can also be used for starting the engine at the same time.

    本公开涉及一种发动机启动控制方法、装置、介质、整车控制器及车辆。其中,在混合动力车辆中,驱动电机的一端通过离合器与发动机连接,另一端与车轮传动连接,方法包括:获取驱动电机的输出扭矩和离合器的接合状态;在离合器处于打开状态、且驱动电机的输出扭矩小于驾驶需求扭矩时,控制驱动电机通过离合器启动发动机。这样,通过电机系统即可实现发动机启动,而无需在混合动力车辆上额外搭载12V起动机系统、12VBSG系统或高压BSG系统,降低了整车成本。电机系统为高压系统,启动功率较高,可将发动机转速拖动到较高转速,从而可快速启动发动机。此外,在行车过程中,驱动电机既可单独为混合动力车辆提供行驶驱动力,同时也可用于启动发动机。
