This invention relates to a wheel speed controller in an anti-lock brake system for avoiding the locking of wheels when a vehicle such as an automobile is braked. In addition to a main brake pressure controller (15) operating primarily on the basis of a differential type judgement, an integration type brake pressure controller (16) is used in order to detect an excessively small slip speed state due to insufficiency of a brake pressure in a wheel lock recovery process, which could not be detected by the differential type main brake pressure controller (15), to apply a small pressure with a small increase rate of a brake pressure and to make the wheel speed control more accurate and more effective. |
