The invention discloses an electronic control hydraulic type brake boosting system comprising a brake booster hydraulic system and a brake booster hydraulic cylinder body. A first piston and a secondpiston are arranged in an inner cavity of the brake boosting hydraulic cylinder body; a boosting cavity partition plate is fixed in the inner cavity of the brake boosting hydraulic cylinder body between the first piston and the cylinder top of the brake boosting hydraulic cylinder body so as to form a boosting cavity. A boosting cavity push rod is fixed to the first piston and penetrates the boosting cavity partition plate; a main push rod sliding hole is concavely formed in the end part of the boosting cavity push rod; a main push rod is inserted into the cylinder top of the brake boosting hydraulic cylinder body and is in sliding fit with the main push rod sliding hole; and a displacement sensor is arranged in the main push rod sliding hole and can detect the relative displacement of themain push rod and the boosting cavity push rod. According to the brake boosting hydraulic system, the pressure of oil in the boosting cavity is controlled according to a displacement signal, and thencontrol over the first piston and the second piston is achieved. The system is simple in structure, the piston is controlled by controlling the pressure of oil in the boosting cavity, and the systemis convenient and reliable.
