Abstract
A brake control device is applied to a vehicle including a regenerative generator. The brake control device includes a pressure adjustment unit that includes an electric pump and a pressure adjustment valve, and that adjusts adjustment liquid pressure of a pressure adjustment fluid path between the electric pump and the pressure adjustment valve; and a controller that controls the electric pump and the pressure adjustment valve. The controller, before starting a replacement operation to replace a regenerative braking force by the regenerative generator with a friction braking force by the adjustment liquid pressure, performs preceding pressurization to increase the adjustment liquid pressure from '0' and maintain the adjustment liquid pressure at predetermined liquid pressure, and after performing the preceding pressurization, increases the adjustment liquid pressure more than the predetermined liquid pressure by increasing a rotation speed of the electric pump, and then execute the replacement operation.
