The invention belongs to the technical field of power transmission and control, and particularly relates to a multi-mode series-parallel hybrid electric vehicle driving system which comprises a battery electrically connected with a first motor and a second motor, an engine, a gear shifting device and an inverter arranged between the battery and the first motor and between the battery and the second motor. The tail end of the gear shifting device is sequentially connected with a main reduction large gear, a differential mechanism and wheels, the second clutch and the first clutch are sequentially arranged at the tail end of the engine, and a fourth gear connected with the first motor and the fifth gear is arranged between the second clutch and the first clutch; the engine is further connected with a second gear and a third gear through the first clutch, the second gear and the third gear are connected with the gear shifting device, the second gear is connected with a seventh gear, the third clutch is connected with a sixth gear, and the synchronizer selectively controls power to be output from the sixth gear or the seventh gear. The second motor is connected with the main reduction large gear through the first gear and the main reduction small gear. On the basis of a series-parallel hybrid power structure, the clutch and the pair of gears are additionally arranged at the engine end, and the fuel economy and the dynamic property of a series-parallel hybrid power automobile are effectively improved.
