The invention discloses a double-rotor motor planetary gear type hybrid power system and an operating mode switching method. The hybrid power system comprises an engine, clutches, a double-rotor motor, an internal gear, an external gear, locking devices and a planetary gear train. By controlling the state of the engine, an inner rotor and an outer rotor in the double-rotor motor, the first clutch, the second clutch, the third clutch, the first locking device and the second locking device, the double-rotor motor planetary gear type hybrid power system can operate among a pure electric operating mode, an operating mode of starting the engine through the motor, an operating mode of single driving of the engine, an operating mode of combined driving of the engine and the motor, an operating mode of engine driving and motor charging, and an operating mode of motor braking energy recovery, and the starting function of the engine is finished by utilizing the double-rotor motor; an engine flywheel is omitted and replaced by the inner rotor of the double-rotor motor, and therefore the system structure is more compact. The adaptability and the operating efficiency of the hybrid power system are improved.
