The invention relates to a range extender starting control method and device, a vehicle control unit and a medium. The method comprises the following steps: according to the current rotating speed andthe current water temperature of a range extender, the target output torque of an ISG motor in the range extender is determined, wherein the current rotating speed and the target output torque are inversely proportional; and the ISG motor is controlled to perform power output according to the target output torque so as to drag an engine in the range extender to operate; and when the next rotatingspeed of the engine reaches the target rotating speed, the engine is controlled to inject oil for ignition, so that starting of the range extender is completed. According to the method, vibration andnoise in the starting process of the range extender can be reduced. 本申请涉及一种增程器启动控制方法、装置、整车控制器和介质。该方法包括：根据增程器的当前转速和当前水温，确定增程器中的ISG电机的目标输出扭矩，其中，所述当前转速和所述目标输出扭矩之间成反比关系；控制所述ISG电机按照所述目标输出扭矩进行动力输出，以拖动增程器中的发动机运行；当所述发动机的下一转速达到目标转速时，控制
