The invention discloses a multi-working-mode series-parallel hybrid power coupling system which solves the problems that existing working modes are few, power is interrupted during gear shifting, the utilization rate of a motor is low, and endurance is difficult. Comprising an engine, a first motor, a second motor, an engine damping device, a first clutch, a second clutch, a third clutch, a fourth clutch, a gearbox, a first transmission shaft, a second transmission shaft, a first meshing gear, a second meshing gear, a gear ring, a locking device, a planet wheel, a planet carrier, a sun wheel, a main speed reducer, a drive axle, an axle and wheels. When the driving mode is switched, different power sources are dynamically coupled in the planetary gear mechanism by controlling the working states of the clutch and the locking device; various modes such as an engine direct drive mode, a single-motor pure electric mode, a dual-motor pure electric mode, an engine and single-motor hybrid drive mode, a three-power-source power dividing mode, a series range extending mode, a dual-motor mutual charging mode, an engine driving charging mode, a parking charging mode and a braking energy recovery mode can be achieved. And driving modes are switched in a coordinated mode through an appropriate control strategy, so that the engine and the motor are in a high-working-efficiency area for a long time.
