<p>A brake controlling apparatus (electronic control unit (1)) of a braking device including a booster valve (50, 51, 52, 53) to be opened at a time of request to boost a pressure of a brake liquid to supply to a wheel (W FR , W RL , W RR , W FL ) to be controlled, and a piston pump (69A, 69B) for supplying pressurized brake liquid to an upstream side of the booster valve (50, 51, 52, 53), the brake controlling apparatus including a brake liquid pressure controlling means that sets a duty ratio between a closing period and a opening period of the booster valve (50, 51, 52, 53) so that a dischargeable period of the brake liquid in the piston pump (69A, 69B) appears in the opening period of the booster valve (50, 51, 52, 53), and controls the booster valve (50, 51, 52, 53) based on the duty ratio.</p> |
