Abstract
An anti-skid brake control system includes a fluid pump which facilitates brake release when wheel deceleration, as indicated in a derived wheel acceleration value, exceeds a predetermined level. Since at low vehicle speeds, the sensors used to derive the wheel acceleration value are of unsatisfactory accuracy, the wheel acceleration value itself may be inaccurate. Accordingly, at low vehicle speeds, the fluid pump is effectively disabled by replacing the derived wheel acceleration value with a fixed value greater than the predetermined level.
