The hybrid power module comprises a motor, a planetary gear system, and a first clutch. The planetary gear system is provided with at least three rotating shafts, which respectively are: a rotating shaft X, a rotating shaft X, and a rotating shaft X. The first clutch is arranged between any two of the three rotating shafts. A power output shaft of the engine is connected to the rotating shaft X or the rotating shaft X and to a second input shaft of the dual input shaft speed change mechanism. A rotor of the motor is connected to the rotating shaft X or to the rotating shaft X. The rotating shaft X is connected to a first input shaft of the dual input shaft speed change mechanism.
