Brake control apparatus and control method thereof

摘要

The controllability in the control for restraining slip of wheels is improved. A brake control apparatus (20) includes: wheel cylinders (23) that apply braking force individually to wheels by supplying a working fluid; retention valves (51 to 54) that are provided respectively upstream of the wheel cylinders (23) and that are opened and closed so as to restrain slip of the wheels; a common control valve (66,67) provided upstream of the retention valves (51 to 54) to supply the working fluid to the wheel cylinders (23); and a control portion (70) that controls the control valve (66,67) by different control laws so as to restrain a fluctuation in pressure on a primary side of the retention valves (51 to 54) caused by a fluctuation in a capacity to which the working fluid from the common control valve (66,67) is supplied, by opening or closing of the retention valves (51 to 54).
Also a break control method is disclosed.
