The invention relates to an electronic brake boosting system and method, and belongs to the field of automobile braking. The system comprises a double-cavity main cylinder, a main cylinder hydraulic sensor, a two-position three-way electromagnetic valve I, a pedal simulator, a displacement sensor, a two-position three-way electromagnetic valve II, a pressurizing cylinder hydraulic sensor, a main pressurizing mechanism, a liquid storage tank and a brake pedal. The system has the advantages that: the structure is novel, the motor is used as a booster power source to replace an original vacuum source for brake booster, hydraulic decoupling is completed in cooperation with the electromagnetic valves, and the two two-position three-way electromagnetic valves are used for hydraulic decoupling. Compared with five electromagnetic valves commonly used at present, the cost advantage is achieved, control is easy, the reaction speed is high, and the robustness is high. By controlling the two two-position three-way electromagnetic valves and the main pressurizing mechanism, the control system is controlled to form switching between braking and pressurizing logic.
