摘要： In a brake control apparatus (20) that controls braking forces which are applied to wheels based on the pressure of a brake fluid, when a hydraulic pressure actuator (40) controls the hydraulic pressure that is transferred to wheel cylinders (23) using the hydraulic pressure of the brake fluid in a power hydraulic pressure source (30), a brake ECU (70) closes a simulator cut valve (68) if the pressure of the brake fluid in the power hydraulic pressure source (30) falls below a predetermined value (Pssc) or if it is determined that the number of times the brake operation member (24) is operated within a predetermined value. In addition, the ECU (70) may change the timing for closing the simulator cut valve (68) based on the road surface condition estimated at the time of antilock control start. Thus, a driver is less likely to feel unusual brake feel when a braking control mode is changed.
