The invention provides a hybrid power system suitable for a four-wheel-driving automobile. The hybrid power system comprises an engine, a motor and a coupling box, wherein the coupling box comprises a plurality of synchronizers, a second shaft, a third shaft and a plurality of gears, the gears on the second shaft comprise the first gear of the second shaft, the second gear of the second shaft and the third gear of the second shaft, the first gear of the second shaft is sleeved on the second shaft, a first gear of the second shaft is connected with the second shaft in a co-rotating mode through a synchronizer, a second gear of the second shaft and a third gear of the second shaft are installed on the second shaft in a co-rotating mode, gears on the third shaft comprise a first gear of the third shaft and a second gear of the third shaft, and the first gear of the third shaft and the second gear of the third shaft are connected with the third shaft in a co-rotating mode through synchronizers respectively; the first gear of the second shaft is meshed with the first gear of the third shaft, the second gear of the second shaft is meshed with the second gear of the third shaft , the third shaft transmits drive to the drive axle, an engine transmits drive to the first gear of the second shaft, and the motor transmits drive to the third gear of the second shaft. The hybrid power system is advantaged in that different power output modes are obtained, the structure is simple, the size is small, and the cost is low.
