The invention discloses a hybrid electric vehicle power transmission system and a power transmission method thereof. The system comprises an engine, a gearbox, a torsion damper, a motor output shaft and a motor, the gearbox comprises an input shaft and an output shaft, and the input shaft is fixedly connected with the driven end of the torsion damper; the input shaft is sleeved with a first driving gear and a second driving gear in a spaced mode. The first driving gear and the second driving gear are each provided with a joint gear ring, the first bilateral synchronizer is located between thefirst driving gear and the second driving gear and connected with the input shaft, and the input shaft is connected with or separated from the first driving gear and the second driving gear through left-right movement of a joint sleeve of the first bilateral synchronizer. The problem of power interruption in the gear shifting process of the gearbox is solved, and meanwhile four-gear engine driving, three-gear pure electric driving, two-mode parking power generation and engine starting are achieved.
