The invention relates to a series-parallel configuration plug-in hybrid power system and a control method thereof. The series-parallel configuration plug-in hybrid power system comprises an engine, afirst driving motor, a second driving motor, a power storage battery, an input shaft, a first intermediate shaft, a second intermediate shaft and an output shaft, and the input shaft is connected to afirst gear and a first synchronizer in sequence; one end of the output shaft is sequentially connected to a second synchronizer, a seventh gear, a fourth gear, a third synchronizer, a fourth synchronizer and a fifth gear, and the other end of the output shaft is used for driving a vehicle to run. The first intermediate shaft is sequentially connected to a second gear, a third gear and the first driving motor; the second intermediate shaft is sequentially connected to an eighth gear, a sixth gear and the second driving motor; the first driving motor and the second driving motor are both connected to the power storage battery; and the engine is connected to the input shaft through a clutch. Compared with the prior art, the system can prevent the engine from being dragged reversely, and hasthe advantages of high working efficiency, quick response, good fuel economy and the like.
