The invention discloses an automatic pressurizing system of a hydraulic booster, which comprises the hydraulic booster, a power steering gear, an oil tank and an oil pump which are sequentially connected in series through a hydraulic pipeline to form a closed loop, and an energy storage device is arranged in the hydraulic booster; the automatic pressurizing system is characterized in that an electric control throttle valve is arranged on a hydraulic pipeline between the hydraulic booster and the power steering gear. The invention further discloses a control method for the automatic pressurizing system of the hydraulic booster. The control method is characterized by comprising a pressure detection method and a method for controlling pressurizing and pressure releasing of the energy accumulator of the hydraulic booster through the electric control throttle valve. The system has the beneficial effects that the structure is simple, full-automatic adjustment is achieved, and the driving safety can be effectively improved.
