ABSTRACT:
An anti-lock controller controls an anti-lock brake system so as to realize any of a pressure decreasing mode where a normally-opened electromagnetic valve is closed, while a normally-closed electromagnetic valve is opened, a holding mode where the normally-opened electromagnetic valve is closed and the normally-closed electromagnetic valve is closed, and a pressure increasing mode where the normally-opened electromagnetic valve is opened, while the normally-closed electromagnetic valve is closed. Then, in the holding mode, for example, in the event that a predetermined condition is established where the voltage of a power supply for a vehicle or the terminal voltage of the normally-opened electromagnetic valve is equal to or smaller than a set value which is determined in advance, a current value that is applied to the normally-opened electromagnetic valve is controlled so as to become smaller than a current value that is applied to the normally-opened electromagnetic valve in the pressure decreasing mode.
