The invention provides an electromechanical coupling system of a hybrid electric vehicle, which belongs to the technical field of hybrid electric vehicles and comprises an engine, a motor, a clutch assembly and a speed change mechanism. An output gear of the speed change mechanism is connected with a driving gear of the differential mechanism, power of the speed changer is input to the differential mechanism, the electromechanical coupling system of the hybrid electric vehicle adopts a double-clutch and single-motor coupling mode, the speed change mechanism is more compact due to the double clutches, and the whole electromechanical coupling system is simpler in structure due to the design of the single-motor coupling system. And meanwhile, the speed change mechanism with the double clutches can better meet the requirements of the hybrid electric vehicle for the torque and the vehicle speed under different working conditions, the power matching performance of the hybrid electric vehicle is remarkably improved, and the dynamic property and the fuel economy are remarkably improved.
