The invention discloses a split-flow type hybrid power device of an automobile. Comprising an engine, a planetary gear mechanism, a first motor, a second motor, an input shaft connected with a planet carrier of the planetary gear mechanism, a synchronizer gear shifting mechanism connected with a sun gear of the planetary gear mechanism, a first one-way brake connected with the synchronizer gear shifting mechanism and a second one-way brake used for braking the planet carrier of the planetary gear mechanism. The output gear is connected with a gear ring of the planetary gear mechanism, the intermediate gear is connected with a rotor of the second motor, a rotor of the first motor is connected with a sun gear of the planetary gear mechanism, and the intermediate gear and the output gear are meshed with the primary driven gear. According to the split-flow type hybrid power device of the automobile, the one-way brake which is low in cost and simple in structure is adopted to be matched with the synchronizer gear shifting mechanism to brake the first motor, an engine direct driving gear is formed, the problems that the electric power flow efficiency is low, and the cost is high due to the arrangement of a clutch are solved, and therefore the cost can be reduced.
