The invention discloses a power system of a hybrid electric vehicle, particularly relates to an integrated type planetary gear oil-electricity parallel serial two-mode hybrid power system, and overcomes the defects that the climbing ability is limited at a low speed and the transmission efficiency is lower at a high speed area of the current single-mode hybrid power system. The integrated type planetary gear oil-electricity parallel serial two-mode hybrid power system comprises a front planetary row, a rear planetary row, a clutch, a brake and a motor system. The front planetary row comprises a front row planetary carrier power input shaft, a shared gear ring and a front row sun wheel axle; the rear planetary row comprises a rear planetary carrier body frame power output gear and a rear row sun wheel axle; the rear planetary carrier body frame power output gear is supported on the rear row sun wheel axle through a sliding bearing; the rear row sun wheel axle is supported on the front row sun wheel axle through another sliding bearing; a motor/generator MG II is matched with the front row planetary carrier power input shaft 1 through another sliding bearing; the motor/generator MG II is connected with the shared gear ring through splines; a motor/generator MG I is connected with the front row sun wheel axle through splines.
