The invention provides a longitudinally-arranged dual-motor hybrid power transmission system and a control method thereof. The transmission system comprises an engine, a first motor, a planet row, a second motor, a speed reducing mechanism and a rear axle which are sequentially arranged from front to back. A flywheel of the engine is connected with a planet carrier of the planet row through an input shaft, and a sun gear of the planet row is arranged at the rear end of a motor shaft of the first motor. A gear ring of the planet row is connected with the rear axle through an output shaft, and the output shaft is coaxial with the input shaft. The speed reducing mechanism comprises a first gear, a second gear, a third gear, a fourth gear, a fifth gear, a sixth gear, a synchronizer and an intermediate shaft, the first gear is arranged at the rear end of a motor shaft of the second motor, and the fourth gear and the sixth gear are both arranged on the output shaft; the second gear, the third gear, the fifth gear and the synchronizer are all arranged on an intermediate shaft, and the intermediate shaft is parallel to the output shaft. According to the invention, energy conservation and consumption reduction of the vehicle can be well realized.
