Abstract: The present invention is a vehicle brake device in which a brake fluid pressurized by a first pressurizing device and a second pressurizing device is supplied to wheel cylinders, wherein the vehicle brake device is provided with: an acquiring unit that acquires a heating correlation value indicating a heating state of the first pressurizing device; and a control unit that executes a first control that decreases the electric power supplied to the first pressurizing device when the heating correlation value acquired by the acquiring unit is equal to or larger than a prescribed threshold value, and a second control that controls the second pressurizing device to compensate for changes in the wheel pressures, i.e., the fluid pressures inside the wheel cylinders, accompanying the execution of the first control.

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.
