The invention provides a hybrid power speed change system and a vehicle, and belongs to the technical field of vehicles. The hybrid power speed change system comprises an engine, a planetary gear train, a double-rotor motor, a speed reduction mechanism and an output shaft. The planetary gear train comprises a planet carrier, a sun gear, a planet gear and a gear ring, the sun gear is sleeved with the gear ring, the planet gear is located between the gear ring and the sun gear, the input end of the planet carrier is connected with the engine, and the output end of the planet carrier is connected with the planet gear. The dual-rotor motor comprises an inner rotor, an outer rotor, a stator and a battery pack, the stator is provided with a first coil and a second coil, the battery pack drives the outer rotor through the first coil, and the inner rotor charges the battery pack through the second coil. The inner rotor is coaxially connected with the sun gear, and the outer rotor is connected with the input end of the gear ring. The gear ring, the speed reducing mechanism and the output shaft are sequentially in transmission connection, and the output shaft drives wheels. The size of the double-rotor motor is small, so that the size of the hybrid power speed control system is small, and the hybrid power speed control system can be conveniently arranged in a vehicle.
