METHOD OF CONTROLLING ELECTRIC BOOSTER FOR IMPROVING HETEROGENEOUS BRAKING PROPERTIES

A method of controlling an electric booster including a reaction disk, a boosting body and a pedal push rod connected to a pedal and configured to come into contact with the reaction disk, the electric booster being subjected to braking control according to a braking map, includes: a first braking control step of controlling and generating a reaction force at normal times in accordance with a pedal effort by compressing and expanding a fluid while moving the pedal push rod; and a second braking control step of controlling and generating the reaction force in accordance with the pedal effort only in a condition in which the reaction disk and the pedal push rod are in contact with each other by detecting a size of an air gap between the reaction disk and the pedal push rod.
