Title:
VEHICLE BRAKE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2015027821
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle brake control device capable of suppressing generation of impact noise by suppressing hydraulic pulsation when brake fluid flows in a drive hydraulic chamber side from a high hydraulic pressure source.SOLUTION: A vehicle brake control device is constituted by comprising: a master cylinder 1 which communicates a high hydraulic pressure source 6 with a drive hydraulic chamber 23 by transfer of a spool valve 21 according to a brake operation, assists a power piston 22, and generates master cylinder pressure Pmc in master hydraulic chambers, 111, 112; a hydraulic control unit 3 as a wheel cylinder hydraulic pressure supply source capable of boosting the wheel cylinder pressure Pwc by supplying brake fluid to brake circuits 71, 72; and a brake control device 4 which controls boosting by the hydraulic control unit 3, in which the brake control device 4 executes boosting processing for performing the boosting by the hydraulic control unit 3 in addition to the master cylinder pressure Pmc to wheel cylinders WC1-WC4 when the brake operation is started.
