The invention discloses a dual clutch transmission (DCT) hybrid power drive system based on synchronizer coupling. The system comprises an internal combustion engine, an ISG motor which is integrated at the front end of a dual clutch transmission and the dual clutch transmission which is connected with a differential mechanism mounted at a rotating shaft of an automobile wheel, wherein the dual clutch transmission comprises an odd input shaft and an even input shaft which are connected with an engine, the rotating shaft of the motor and an output shaft; the front end of the output shaft is supported in a motor input shaft gear inner circular hole by a needle bearing; the rear end is supported on a transmission rear end shell by a bearing; the ISG motor is capable of realizing dynamic coupling or decoupling with the engine in full gears to realize various working modes of the hybrid power system. The arrangement of a reverse gear is omitted in the hybrid power drive system, the hybrid power drive system is com
