Abstract
An anti-skid brake control system includes a device for detecting the friction level of a road surface. The system performs mutually different modes of arithmetic operation for deriving wheel acceleration data on the basis of wheel speed monitoring data. Respective modes of arithmetic operations are provided different levels of response characteristics and noise elimination levels adapted for road friction levels. The system selects one of the arithmetic operation modes for deriving the wheel acceleration data depending upon the friction level on the road surface.
