ABSTRACT:
An anti-skid control system of a vehicle includes a wheel speed sensor for sensing a wheel rotation speed, a hydraulic pressure adjusting device for adjusting a brake pressure of hydraulic fluid of the control system, and an anti-skid brake controller for controlling the hydraulic pressure adjusting device based on the wheel rotation speed detected. The brake pressure is cyclically changed in accordance with a control cycle including at least a pressure reduction phase in which the brake pressure is reduced and a pressure increase phase in which the brake pressure is increased. A brake pressure control device detects the pressure reduction amount based on a wheel operation parameter. A brake pressure reducing action is repeatedly executed in the pressure reduction phase at a predetermined interval. Braking performance can be improved by use of the system of this invention.
