    Abstract: The vehicular brake device includes a determination unit, a ratio setting unit, and the control unit. The determination unit determines the operating condition of a vehicular brake device. The ratio setting unit sets, on the basis of the result of determination by the determination unit, a first ratio which is the ratio of a wheel pressure generated by a piston drive unit to a target wheel pressure, and a second ratio which is the ratio of a wheel pressure generated by a hydraulic pressure adjusting unit to the target wheel pressure. The control unit controls the piston drive unit and the hydraulic pressure adjusting unit on the basis of the first ratio and the second ratio.

    Abstract: This vehicle brake device comprises: a simultaneous driving determination section which determines whether it is necessary to simultaneously drive an upstream-side motor and a downstream-side motor; and a PWM control section which, when the determination result by the simultaneous driving determination section is in the affirmative, changes the duty ratio of the PWM signal to be output to the upstream-side motor so as to be smaller than when the determination result by the simultaneous driving determination section is in the negative, and uses PWM control to drive the upstream-side motor.

    Abstract: A vehicle-use brake apparatus has a control unit which includes a correcting pressure acquisition section that acquires a flow rate correcting pressure corresponding to a discharge amount of brake fluid discharged by a pump, a command differential pressure acquisition section that acquires a command differential pressure by performing a flow rate correction where the flow rate correcting pressure is subtracted from a target wheel cylinder pressure, and a correction restriction section that performs a correction restriction by which the flow rate correcting pressure is reduced or the flow rate correction is not performed if an actual wheel cylinder pressure is smaller than a target wheel cylinder pressure.

    Abstract: A braking device includes: a reservoir; a master cylinder in which when the amount of operation performed on a brake pedal reaches or exceeds a predetermined amount, a port communicating between a pressure chamber and the reservoir is cut off and hydraulic pressure corresponding to the brake pedal operation amount is generated; a hydraulic pressure unit for adjusting the wheel cylinder hydraulic pressure; and a control unit for controlling the hydraulic pressure unit. The control unit determines, based on a temperature-related value related to the temperature of a friction member pressed by the wheel cylinder hydraulic pressure against a rotating member fixed to a wheel, whether the friction member is in a fade state. When the friction member is in a fade state, the control unit controls the hydraulic pressure unit to suction brake fluid from the reservoir through the port, and is fed to the wheel cylinder.

    Abstract: A braking device includes a stroke simulator, a hydraulic pressure generation unit, a reaction hydraulic pressure detection unit, a master hydraulic pressure detection unit, and a bottoming determination unit. The stroke simulator includes a cylinder and a piston slidably movable inside the cylinder in conjunction with an operation of a brake operation member. The stroke simulator causes a reaction force chamber to generate a reaction hydraulic pressure and applies a reaction force. The hydraulic pressure generation unit generates a master hydraulic pressure by driving a master piston and supplies a hydraulic pressure to a wheel cylinder. The reaction hydraulic pressure detection unit detects the reaction hydraulic pressure. The master hydraulic pressure detection unit detects the master hydraulic pressure. The bottoming determination unit determines whether the master piston is in a bottoming state based on the reaction hydraulic pressure and the master hydraulic pressure.
