The invention discloses a single-clutch dual-motor multi-gear hybrid power driving system, which can realize the functions of pure electric driving, series driving, parallel driving, speed regulation and gear shifting and the like by only utilizing one clutch. Compared with a steam EDU GEN1 system, a clutch at the end of a driving TM motor is omitted, precise speed regulation and gear shifting of the TM motor are achieved through control, various mode functions of the hybrid power system are achieved, and meanwhile the cost of the power system is reduced. Compared with a public P2 system, series efficient charging and driving can be achieved, good drivability and economical efficiency are achieved at the low speed and the low electric quantity, an engine can be started through a single motor, and the drivability problem caused when the P2 system is started in a sliding friction mode is solved. Compared with a Ba Dii P3 system, the motor is arranged at the front end of the gearbox, gear shifting can be achieve
