In a hydraulic brake system, when a main power supply is in an abnormal condition in which it cannot supply electric power to a pump motor, etc., the pump motor is operated with electric power supplied from an auxiliary power supply, irrespective of the presence of a braking request. Thus, when the main power supply is in the abnormal condition, the number of times inrush current flows is reduced. As a result, the voltage of the auxiliary power supply is less likely to be lower than an operation minimum voltage, and the hydraulic brake system is less likely to be unable to be operated.
