Abstract: A brake device includes: a first pressurizing unit configured to increase a WC pressure by supplying brake fluid into wheel cylinders provided in wheels RL and RR; a second pressurizing unit connected to a reservoir tank via a fourth flow passage and configured to increase the WC pressure by supplying the brake fluid taken in from the reservoir tank into the wheel cylinders; and a brake control unit configured to control at least one of the first pressurizing unit and the second pressurizing unit based on a target WC pressure. The brake control unit is configured to, when the WC pressure is to be increased by operating the second pressurizing unit, execute an auxiliary brake control in which the first pressurizing unit is operated to assist the second pressurizing unit to increase the WC pressure.

Abstract: A control device includes an electric motor, a battery, a capacitor, a power source selection portion, a determination unit configured to determine whether the battery is normal, and a control unit configured to select, as a control mode of the electric motor, one of a first mode and a second mode in which a power consumption amount of the electric motor is reduced as compared to when the electric motor is driven in the first mode, and drive the electric motor in the selected control mode. When the battery is transitioned from a state of being determined to be normal to a state of being determined to be not normal, the control unit switches the control mode from the first mode to the second mode and then makes the power source selection portion select the capacitor.
