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.

Abstract: Vibrations of a hydraulic pressure in an upstream portion due to operations of a slip control device during anti-lock control are transmitted to a control pressure chamber via a pressurizing piston of a master cylinder and a control piston of a regulator. During anti-lock control, in contrast, a pressure-increase linear valve and a pressure-reduction linear valve are opened, allowing change in volume of the control pressure chamber, resulting in reduction in stiffness. This reduction suppresses vibrations of a hydraulic pressure in the control pressure chamber, resulting in suppression of vibrations of a hydraulic pressure in a front pressure chamber. As a result, it is possible to reduce the lowering in control accuracy for a hydraulic pressure in a brake cylinder in anti-lock control using the hydraulic pressure in the front pressure chamber, which can well avoid a long braking distance.

Abstract: A hydraulic brake system, including: a brake operation member; a brake device; a master cylinder; a communication switching valve; a low-pressure-source shut-off valve; a high-pressure source; a regulator; a pressure adjuster; and a controller, wherein, when a pressurizing state of the master cylinder is switched from a first pressurizing state to a second pressurizing state after initiation of an operation on the brake operation member, the controller executes a pressurizing-state switching control in which switching of a state of the low-pressure-source shut-off valve from an open state to a closed state and switching of a state of the communication switching valve from a closed state to an open state are carried out after a pressure-regulating state of the regulator has been switched from a first pressure-regulating state to a second pressure-regulating state by controlling the pressure adjuster to increase a second pilot pressure while the first pressurizing state is maintained.
