Abstract: A braking control device includes an upstream mechanism control unit, a determination unit, and a control unit. The upstream mechanism control unit is configured to feedback control the upstream mechanism in such a manner that a detected hydraulic pressure detected by a hydraulic pressure sensor is brought to an upstream target hydraulic pressure. The hydraulic pressure sensor detects a hydraulic pressure of the hydraulic pressure circuit. The determination unit is configured to determine, based on the detected hydraulic pressure by the hydraulic pressure sensor, whether hydraulic pressure hunting is occurring. The control unit is configured to control the downstream mechanism based on the upstream target hydraulic pressure and the target wheel pressure in a case where the determination unit determines that the hydraulic pressure hunting is occurring.

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 brake device includes a stroke simulator, a stroke sensor, and a brake start determination unit. The stroke simulator includes a cylinder, a piston, an orifice, and a pressure sensor. The cylinder defines a liquid pressure chamber to which a brake liquid is supplied via a fluid path. The piston slides in the cylinder by the brake liquid supplied to the liquid pressure chamber. The orifice is formed in the fluid path. The pressure sensor detects a reaction pressure. The stroke sensor is configured to detect the stroke. The brake start determination unit determines an operation of the brake operation member has been started in a case where the reaction pressure detected by the pressure sensor becomes equal to or greater than a first threshold value and the stroke detected by the stroke sensor becomes equal to or greater than a second threshold value.
