The invention belongs to the field of new energy automobiles, and particularly relates to a hybrid power coupling system, a control method thereof and a hybrid electric vehicle. The hybrid power coupling system comprises an engine, a first motor, a second motor, a planetary gear mechanism, a first transmission shaft, a first clutch, a first gear, a driving mechanism and a gear shifting mechanism; a rotor of the first motor is connected with an output shaft of the engine, the second motor is arranged at the end, away from the engine, of the first motor, the planetary gear mechanism is partially arranged in the second motor and connected with a rotor of the second motor, the first transmission shaft is connected with the planetary gear mechanism, and the first clutch is connected with the rotor of the first motor and the first transmission shaft. The first gear is connected with the planetary gear mechanism, the driving mechanism is in transmission connection with the first gear, and the gear shifting mechanism is connected with the planetary gear mechanism and the first transmission shaft. The gear shifting mechanism controls the transmission path between the first transmission shaft and the first gear, two-gear power output is achieved, and the dynamic property and economical efficiency of the whole vehicle are improved.
