The invention discloses a serial-to-parallel control method of an electrical-electric connecting type hybrid power system. The method is that when a vehicle meets the condition of entering parallel connection and an engine is failed to be started, ISG (Integrated Starter Generator) is subjected to rotating speed control, namely, the target rotating speed is the rotating speed of a main motor; the engine supplies air when reaching the set rotating speed n1, and is ignited when reaching the set rotating speed n2; when starting successfully, the ISG remains the rotating speed control; on the basis of the rotating speed of the main motor, the engine control is replaced by accelerator control, and a proper accelerator value is provided; when the rotating speed difference between the engine and the main motor is less than the set rotating speed difference value, a clutch is connected, and the vehicle enters the parallel connection mode. The method has the outstanding characteristics that the ISG is subjected to rotating speed control under a serial-to-parallel mode; the engine is subjected to accelerator control and the proper accelerator value is provided on the basis of the rotating speed of the main motor, so that the speed regulating can be responded fast; in addition, the response of the engine in the parallel connection mode is faster than that of the mode that the engine control is performed and the accelerator value is 0 during speed adjustment; the hybrid power system is free of power cut-off after the clutch is connected.
