Abstract

A braking apparatus according to an embodiment includes: a fluid pressure circuit that is provided between a master cylinder and a wheel cylinder, and that includes both a first system flow channel connecting a reservoir and at least one of the plurality of wheel cylinders, and a second system flow channel connecting at least one of the plurality of wheel cylinders and the master cylinder, and that forms a flow channel for supplying operating fluid to each of the wheel cylinders; and a pump provided in the first system flow channel and driven by the motor to increase the fluid pressure of the operating fluid to be supplied from the reservoir to the wheel cylinders. A control unit controls the driving state of the pump in order to drive, when a predetermined fail standard for braking control has been satisfied, the motor in accordance with the information detected by an operating state detection means, and executes fail-safe control for providing braking force by supplying the operating fluid discharged from the pump to the fluid pressure chamber in the master cylinder.
