PROBLEM TO BE SOLVED: To reduce power consumption and heat generation without lowering control quality in a brake control device. SOLUTION: In this brake control device, a wheel cylinder pressure is intensified by driving a pump 4, and the wheel cylinder pressure is reduced by opening an outside gate valve 3 on the other hand. When outputting a control signal to keep the liquid pressure of the wheel cylinder WC, a control signal having a duty ratio corresponding to the liquid pressure of the wheel cylinder WC is outputted. Accordingly, power consumption in the outside gate valve 3 can be reduced and generation of heat can be also suppressed.
