The invention belongs to the technical field of automobile transmission systems, and particularly relates to a hybrid power coupling system and a hybrid electric vehicle. The hybrid power coupling system comprises a power input shaft, a first planet gear row, a second planet gear row, at least two clutches, at least two brakes, a first output gear and a motor driving assembly; two of a first sun gear, a second sun gear and a second planet carrier in the planet gear row are connected with the power input shaft through clutches respectively, two of the first sun gear, the second sun gear and the second planet carrier in the planet gear row are connected with a brake respectively, and a first output gear is arranged on the first planet carrier. The motor driving assembly is connected with the first output gear and wheels. The multiple gears can be formed by controlling the two clutches and the two brakes, a series-parallel connection coupled power system with the multiple gears is formed, the engine can be located in a high-efficiency area in the engine direct drive or parallel drive mode, and the fuel consumption of the whole vehicle is further reduced.
