The invention discloses a dual-mode combined power shunting type parallel-serial mixed power system. The dual-mode combined power shunting type parallel-serial mixed power system is composed of an engine, an input shaft, a planetary gear train, a first motor, a second motor, an inverter, a power battery, a first clutch, a second clutch and an output gear. The planetary gear train comprises a front-row sun gear, a front-row planet wheel, a front-row gear ring, a back-row gear ring, a back-row planet wheel and a planet carrier. The dual-mode combined power shunting type parallel-serial mixed power system is simple in structure; mode switching can be completed by controlling the working state of the two clutches, and control is easily achieved. The dual-mode combined power shunting type parallel-serial mixed power system is a three-node input type power shunting system in a low-speed power shunting mode and is a four-node combined type power shunting system in a high-speed power shunting mode; the higher transmission efficiency is achieved in a full-vehicle-speed scope; in addition, the requirement for the loading power of the second motor can be reduced, and miniaturization of the second motor is facilitated.
