Abstract: A brake control device to be applied to a vehicle having a hydraulic brake generating a hydraulic braking force, which is a braking force converted from a fluid pressure to a wheel of the vehicle, and an electric parking brake generating an electric braking force, which is a braking force different from the hydraulic braking force, on the wheel by a wheel brake mechanism driven by a motor. The brake control device includes an electric parking brake controller for determining a current target value, which is a target value of an electric current through the motor, by using a target braking force, and for controlling the electric parking brake by using the current target value. The electric parking brake controller is configured to estimate the fluid pressure in the hydraulic brake by using a current detection value, which is a detection value of an electric current through the motor.

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.
