Abstract
An anti-lock brake control system capable of performing optimal control of braking hydraulic pressure in a motor vehicle having four wheels while preventing brake application from being released by setting an optimal pseudo vehicle speed by effectively making use of the wheel speeds of four wheels in arithmetic determination of a pseudo vehicle speed on a wheel basis. The anti-lock brake control system includes wheel speed detector (101a to 101d) for detecting rotation speeds of four wheels, respectively, reference wheel speed arithmetic calculators (102a to 102d) for setting limits on the wheel speed of the wheels in consideration of positional relations of the wheels relative to one wheel of concern to thereby determine a reference wheel speed, and pseudo vehicle speed arithmetic calculators (103a to 103d) for arithmetically determining the pseudo vehicle speed on the basis of the reference wheel speed.
