The invention discloses a hybrid power system, a hybrid power vehicle and a hybrid driving method. The hybrid power system comprises an internal combustion engine, a front planetary gear set and a rear planetary gear set. The front planetary gear set comprises a front sun gear, a front planet carrier and a front gear ring. The rear planetary gear set comprises a rear sun gear, a rear planet carrier and a rear gear ring. The front planet carrier of the front planetary gear set is connected with a first motor, a rear gear ring of the rear planetary gear set is connected with a second motor, and the front gear ring of the front planetary gear set is connected with the rear sun gear of the rear planetary gear set. The output end of the internal combustion engine is connected with the front sun gear of the front planetary gear set. The rear planet carrier of the rear planetary gear set is connected with a system output shaft. A front lock-up clutch used for locking or unlocking the front planet carrier is connected to the front planet carrier. A middle lock-up clutch used for locking or unlocking the rear sun gear is connected to the rear sun gear. A rear lock-up clutch used for locking or unlocking the rear gear ring is connected to the rear gear ring. A mode clutch is arranged between the rear gear ring and the rear planet carrier. The hybrid power system, the hybrid power vehicle and the hybrid driving method have the advantages that various hybrid power working conditions including series connection type working conditions can be achieved, and adaptability to different travelling conditions and requirements is improved.
