The invention discloses a hybrid power system, a hybrid power vehicle with the hybrid power system, and a driving method. The hybrid power system comprises an internal combustion engine, a front planetary line and a rear planetary line. The front planetary line comprises a front sun gear, a front planetary carrier and a front gear ring. The rear planetary line comprises a rear sun gear, a rear planetary carrier and a rear gear ring. The front gear ring of the front planetary line is connected with a first motor. The rear gear ring of the rear planetary line is connected with a second motor. The output end of the internal combustion engine is connected with the front sun gear of the front planetary line. The front planetary carrier of the front planetary line is connected with the rear planetary carrier of the rear planetary line. The front sun gear is connected with a front lockup clutch which is used for locking or releasing the front sun gear. The front planetary carrier is connected with a middle lockup clutch used for locking or releasing the front planetary carrier. The rear sun gear of the rear planetary line is connected with an output shaft of the system. The rear gear ring is connected with a rear lockup clutch used for locking or releasing the rear gear ring. A mode clutch is arranged between the rear gear ring and the rear planetary carrier. According to the hybrid power system, the hybrid power vehicle with the hybrid power system, and the driving method, multiple hybrid power working conditions including the series working condition can be achieved, and the adaptability to different traveling conditions and requirements is improved.
