The invention belongs to the technical field of vehicle power systems, and discloses an electromechanical coupling system and a hybrid electric vehicle. The electromechanical coupling system comprises an engine, a first motor, a second motor, a clutch and a battery. A first motor shaft is connected with a differential gear through a first gear set. In the clutch, the driving end is connected with a second motor shaft through a second gear set; the first driven end is connected with the output end of the engine; the second driven end is connected with a differential gear through a third gear set; the third driven end is connected with a differential gear through a fourth gear set; the driving end can be jointed with any one of the three driven ends; the driving end can be connected with the first driven end and the second driven end at the same time. The driving end can be connected with the first driven end and the third driven end at the same time. The battery can supply power to the two motors, and the two motors can also charge the battery. The three power sources can be freely decoupled and freely combined, driving force is output at different gears after being superposed, and the power requirements of different working conditions are met.
