The invention discloses a power driving device, a hybrid power system and a vehicle. The power driving device comprises an engine, a first motor and a second motor, the engine is connected with the first motor through an input shaft, and the first motor comprises a first stator and a first rotor; the planetary gear mechanism comprises a sun gear, a planet gear, a planet carrier and a gear ring, the planetary gear mechanism is connected with an intermediate shaft, the first motor is selectively connected with the intermediate shaft through a clutch, and the planetary gear mechanism is further connected with the output shaft; the first brake is used for braking the intermediate shaft, and the first brake and/or the clutch are/is embedded in the first rotor; the second motor is connected with the sun gear through a second motor shaft, and the second motor comprises a second stator and a second rotor; the second brake is used for braking the second motor shaft, and the second brake is embedded in the second rotor. By embedding the first brake and/or clutch in the first rotor and embedding the second brake in the second rotor, the axial dimension can be significantly reduced.
