Dual-clutch hybrid power coupling system and vehicle

The invention belongs to the field of new energy vehicles, and relates to a vehicle and a dual-clutch hybrid power coupling system which comprises an engine, a generator, a driving motor, a differential mechanism, a first clutch and a second clutch; the engine is connected with a driving part of the first clutch through a first input shaft; a driven part of the first clutch is connected with a driving part of the second clutch; the generator is connected with the driving part of the second clutch through a second input shaft; a driven part of the second clutch is connected with the differential mechanism; the driving motor is connected with the differential mechanism through a third input shaft. By selectively combining or separating the first clutch and the second clutch, whether the engine and the generator participate in driving or power generation can be controlled, so that multiple driving modes are realized, and higher transmission efficiency is obtained; especially, an engine direct drive mode and a du
