Abstract: A braking control device includes a master unit including a master chamber connected to a front wheel cylinder and a servo chamber that applies forward force opposing a reverse force applied to a master piston by the master chamber to the master piston, a pressure adjustment unit that adjusts brake fluid discharged by a pump to a first liquid pressure by a first solenoid valve and introduces the first liquid pressure to a rear wheel cylinder, and adjusts the first liquid pressure to decrease to a second liquid pressure by a second solenoid valve and introduces the second liquid pressure to the servo chamber; and a regenerative coordination unit having an input piston operable in conjunction with a braking operation member and an input cylinder fixed to the master cylinder, and in which a gap between the master piston and the input piston is controlled by the second liquid pressure.

Abstract: A brake control device including a pressure adjusting unit including an electric pump and an electromagnetic valve, and that adjusts, using the electromagnetic valve, a brake liquid discharged by the electric pump to an adjusted liquid pressure and introduces the adjusted liquid pressure to the wheel cylinders of the rear wheels; and a master unit that includes a master cylinder and a master piston, and that includes a master chamber connected to the wheel cylinders of the front wheels and a servo chamber to which the adjusted liquid pressure is introduced and which provides, to the master piston, an advancing force that opposes a retreating force applied to the master piston by the master chamber.

Abstract: A vehicle includes a regenerative generator on a front wheel. A braking control device includes an actuator that applies a front wheel torque and a rear wheel torque, and a controller that individually adjusts the front wheel torque and the rear wheel torque. The controller is configured to determine the front wheel torque and the rear wheel torque to zero when a regenerative braking force Fg generated by the regenerative generator has not reached a maximum regenerative force Fx which is a generatable maximum value. On the other hand, the controller is configured to increase the rear wheel torque from zero before increasing the front wheel torque from zero when the regenerative braking force Fg reaches the maximum regenerative force Fx.

Abstract: A hydraulic circuit comprises: a first pressure-boosting flow path that connects a first main flow path and a first wheel cylinder; a first pressure-boosting valve that is disposed in the first pressure-boosting flow path and that opens in a non-energized state; a first pressure-reducing flow path that connects the first wheel cylinder and a reservoir; a first pressure-reducing valve that is disposed in the first pressure-reducing flow path and that closes in a non-energized state; a second pressure-boosting flow path; a second pressure-boosting valve; a second pressure-reducing flow path; and a second pressure-reducing valve. A control unit comprises: a first drive circuit that controls the first pressure-reducing valve; and a second drive circuit that is separate from the first drive circuit and that controls the second pressure-reducing valve.
