The hybrid electric vehicle transmission system comprises an engine, a first motor and a planetary gear mechanism, and the planetary gear mechanism comprises a rotatable gear ring, a planet carrier, a planet wheel and a sun wheel; the sun gear is coaxially installed on an output shaft of the engine, and an output shaft of the first motor is meshed with the gear ring through a first gear. The planet carrier is provided with a main shaft which is coaxially mounted, and the main shaft is connected to a wheel axle through a gear transmission system; a first brake is arranged on the sun gear or an output shaft of the engine, a second brake is arranged on the planet carrier or the main shaft, and a third brake is arranged on the gear ring. The transmission system of the hybrid electric vehicle has the advantages that impact and vibration generated in the combining and separating process of the clutch can be eliminated, and the smoothness and comfort of the vehicle can be improved.
