The invention provides a series-parallel hybrid power configuration and a control method thereof. According to the series-parallel hybrid power configuration, an engine and two motors are arranged together. Three pairs of gears and two joint sleeves are used, while the switching of four gears can be achieved. The speed ratio range is wide, and the dynamic property and the acceleration property arehigh. The series-parallel hybrid power configuration comprises an engine, an IM motor, a TM motor and a coaxial double-input gearbox, the coaxial double-input gearbox comprises a shell, a first inputshaft, a second hollow input shaft, an output shaft and at least one intermediate shaft, and the first input shaft is coaxially arranged in a center cavity of the second hollow input shaft. An avoiding center cavity is formed in the position, corresponding to the first input shaft, of the IM motor, the hollow transmission end of the IM motor is connected with the input end of the second hollow input shaft, the first input shaft penetrates through the avoiding center cavity and then is connected with one end of a clutch device, and the output end of the engine is connected with the other end of the clutch device. When the clutch device is in a closed state, the engine is connected with the first input shaft.
