The invention discloses a hybrid power system. The hybrid power system comprises a hybrid power driving module, wherein the hybrid power driving module comprises an engine, a driving wheel system, a first motor and a second motor; the first motor comprises a first stator and a first rotor which can freely rotate; the second motor comprises a second stator and a second rotor which can freely rotate; an output shaft of the engine is sequentially, coaxially and fixedly connected with the first stator and the second stator; the rotating direction of the first rotor is opposite to that of the second rotor; and an output shaft of the second rotor is fixedly connected with a driving shaft of the driving wheel system. According to the hybrid power system disclosed by the invention, the rotating freedom degree of the stator of the first motor and the rotating freedom degree of the stator of the second motor are released, and according to the vehicle speed of the driving wheel system, torque of the first motor and torque of the second motor are controlled; and speed adjustment is performed on the engine through the first motor and the second motor, so that the purpose that the rotating speed of the engine and the vehicle speed are completely decoupled is realized.
