ELECTRICALLY ACTUATED BRAKE BOOSTER, VEHICLE WITH ELECTRICALLY ACTUATED BRAKE BOOSTER, AND METHOD OF ELECTRICALLY ACTUATED BRAKE BOOSTING

摘要

PROBLEM TO BE SOLVED: To provide an electrically actuated brake booster capable of restraining the consumption of electric current in an actuator, even in the case where a brake fluid in a wheel cylinder is discharged while the discharged brake fluid is returned to a master cylinder.;SOLUTION: A position control is carried out such that the actuator is kept under a control based on the stroke amount of a brake pedal, and if a decompressive control takes place, a hydraulic pressure control for the actuator is performed based on the level of a hydraulic pressure of the master cylinder.;COPYRIGHT: (C)2010,JPO&INPIT
