The invention discloses a longitudinal series-parallel hybrid power transmission system and a control method. The longitudinal series-parallel hybrid power transmission system comprises an engine, a P1 motor, a P3 motor and a rear axle. The engine, the P1 motor and the P3 motor are coaxially arranged, and the engine and the P1 motor are connected through a speed increasing mechanism so that power can be transmitted between the engine and the P1 motor. The P3 motor is connected with the rear axle through a speed reducing mechanism so as to realize wheel driving; the P1 motor and the P3 motor are connected through a clutch so that connection or disconnection of the engine and the P3 motor can be achieved. The functions of pure electric drive, engine direct drive, series/parallel hybrid power transmission and the like are achieved, and the purposes of energy conservation and consumption reduction of the whole vehicle are achieved. The planet row structure is adopted to solve the problems of insufficient modular design, large radial arrangement space and the like of the system.
