ABSTRACT:
Each time a prescribed cycle comes to an end, an ECU estimates an average retaining amount of brake fluid in a reservoir of the current prescribed cycle on the assumption that a pump has sucked a constant amount of brake fluid in the current prescribed cycle. The ECU calculates deviation between the average retaining amount at the end of the previous prescribed cycle and the average retaining amount at the end of the current prescribed cycle. The greater the deviation is, the greater a deviation correction amount the ECU sets. The ECU performs deviation pump control in which the target suction amount of the pump is set based on the reference suction amount and the deviation correction amount.
