The invention relates to an electric control booster, and belongs to the field of automobile brake systems. Comprising a motor, a transmission system, a valve body and a hydraulic cylinder, the motor, the transmission system and the hydraulic cylinder take the valve body as a carrier, the axis of the motor, the transmission system and the hydraulic cylinder are coaxially fixed on the valve body through screws or fastening glue, one end of the transmission system fixes a first positioning sleeve on the valve body through screws, and the first positioning sleeve is connected with a cylinder body cover through a first small screw. The planetary gear train and the lead screw piston component are limited in the cylinder body cover, a sun gear of the planetary gear train is riveted to a motor rotor shaft in a radial interference mode, the front end of the motor rotor shaft is limited in the radial direction through a second positioning sleeve, and the lead screw piston component is in axial sliding fit with the hydraulic cylinder. The hydraulic cylinder has the advantages that the structure is novel, large input force is provided for the hydraulic cylinder under the small output torque of the motor through a planetary gear train in the speed reducing mechanism, the product size is small, the transmission efficiency is high, the cost is low, and the manufacturing and assembling process is easy to achieve.
