Hydraulic control system with starting and stopping functions and automatic gearbox using same

The invention discloses a hydraulic control system with starting and stopping functions. The hydraulic control system is composed of a high-pressure oil circuit, a gear switching oil circuit, a locking and separating oil circuit, a lubricating oil circuit and a starting and stopping oil circuit; by controlling the on-off states of five hydraulic actuating mechanisms (a first clutch, a second clutch, a third brake, a fourth brake and a fifth clutch), P/R/N/D gears are switched; a hydraulic torque converter is controlled to be switched to be in a locked state or an unlocked state according to different working conditions; and the hydraulic torque converter is in the unlocked state under the working conditions of needing torque increasing such as starting or climbing, and is in the locked state after a certain vehicle speed is reached, thus the high transmitting efficiency is guaranteed, and through an energy storage cavity solenoid valve, when the starting and stopping functions need tobe used, smooth combinati
