Abstract
An anti-lock controller controls the brake fluid pressure of a wheel brake to 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 a duty pressure increasing mode which is corresponds to the pressure increasing mode, values of predetermined values D, Dwhich put a current value to be applied to the normally-opened electromagnetic valve in a relationship such as 100>D>D>0 if in the pressure decreasing mode, a current value resulting when the normally-opened electromagnetic valve is continuously turned on is 100, while a current value resulting when the normally-opened electromagnetic valve is turned off is 0 are repeated at predetermined time intervals.
