In order to solve the starting problem of the hybrid electric vehicle in the prior art, the invention provides an electromechanical coupling system and a hybrid electric vehicle starting control method and device, and the hybrid electric vehicle can have a high starting success rate on an abrupt slope section and have good economical efficiency on a flat road or a relatively smooth ramp. The electromechanical coupling system comprises an engine, a generator, a driving motor, a planetary gear mechanism and a differential mechanism, the engine is coaxially connected with the generator through a first clutch and an input shaft in sequence, the driving motor is connected with the differential mechanism through a transmission device, the planetary gear mechanism comprises a sun gear, a planet carrier and a gear ring, and the axis of the gear ring is fixed to the input shaft. The sun gear is connected with the gear ring through a second clutch, the planet carrier is connected with the differential mechanism through a transmission device, and the system further comprises a brake used for braking the sun gear. The hybrid electric vehicle can have a high starting success rate on an abrupt slope road section and has good economical efficiency on a flat road or a relatively gentle ramp.
