The invention relates to a single-motor hybrid power assembly and a hybrid electric vehicle, and belongs to the technical field of hybrid electric vehicles. The single-motor hybrid power assembly comprises a planetary gear mechanism, a gear selecting mechanism and a motor; the planetary gear mechanism comprises a small sun gear, a large sun gear, a first-stage planetary gear engaged with the small sun gear, a second-stage planetary gear engaged with the first-stage planetary gear and the large sun gear, an outer gear ring engaged with the second-stage planetary gear, and a planet carrier rotationally connected with the first-stage planetary gear and the second-stage planetary gear; and thesmall sun gear and large sun gear are coaxially arranged; the gear selecting mechanism is in transmission connection with an engine and comprises a first clutch and a second clutch, the first clutch is connected with the sun through a first transmission shaft, and the second clutch is connected with the planet carrier through a second transmission shaft; and the motor is connected with the small sun gear through a third transmission shaft. Various motor and engine coupling modes can be achieved, more flexible selection modes can be achieved when different working conditions are coped, and therefore better dynamic property and economical efficiency are achieved.
