Document Type and Number:
WIPO Patent Application WO/2022/181779
Kind Code:
A1
Abstract:
A brake device 40 comprises a hydraulic pressure generation device 41, a brake actuator 60, and a brake control unit 82. The brake control unit 82 executes an assistance process that, according to a master pressure in hydraulic pressure chambers 521, 522 of a master cylinder 43 in the hydraulic pressure generation device 41, or according to an operation-related force which is the operation force inputted to a brake operation member by a driver, controls an assisting hydraulic pressure which is the amount of increase in the wheel pressure due to movement of the brake actuator 60. The brake control unit 82 executes reduction control that reduces/corrects the assisting hydraulic pressure when pistons 511, 512 of the master cylinder 43 are located further in a retreating direction X2 than a second position during the assistance process.
