Abstract
A pressure braking unit including an operating pressure applying unit that applies an operating pressure to a working fluid according to operation of an operating member; a pressurizing unit that applies a pressurized pressure to the working fluid; a braking force generating unit that generates pressure braking force on wheels by a total pressure of the operating pressure and the pressurized pressure; a regenerative braking unit that generates regenerative braking force on the wheels; and a controlling unit that executes switching control to switch the regenerative braking force to the pressure braking force according to the pressurized pressure, and by prohibiting increase in the pressurized pressure by the pressurizing unit, it is possible to inhibit braking operation feeling from deteriorating while ensuring the braking force.
