The invention belongs to the field of new energy vehicles and relates to a hybrid power coupling system and a vehicle. The hybrid power coupling system comprises an engine, a generator, a driving motor, a first planetary gear mechanism and a second planetary gear mechanism; the first planetary gear mechanism comprises a first sun gear, a first planet carrier and a first gear ring; the second planetary gear mechanism comprises a second sun gear, a second planet carrier and a second gear ring; the engine and the generator are connected with an input shaft; the first sun gear is fixedly arrangedon the input shaft; the second sun gear is connected to the first gear ring; the second planet carrier is connected to the first planet carrier; the first planet carrier and the second planet carrierare braked through a first brake; the first gear ring is braked through a second brake; the first gear ring is connected with the input shaft through a second clutch; the second gear ring and the driving motor are connected with an intermediate shaft; and the intermediate shaft outputs power to wheels. The load of the system can be reduced; multiple driving modes can be achieved; higher transmission efficiency is achieved; and the power performance and economy of the whole vehicle are improved.
