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: 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.
