Abstract
The present invention relates to an anti-skid brake control apparatus for a brake system of wheeled vehicles. The control apparatus according to the present invention is essentially composed of a slip speed meter, a threshold value setting device and a brake oil pressure control device. The slip speed meter calculates at least one of a slip speed and a wheel acceleration. The acceleration is a time derivative of the rotational speed of a wheel. The threshold value setting device temporarily determines a threshold value for at least one of the slip speed and the wheel acceleration with reference to at least one of the slip speed and the wheel acceleration. The brake oil pressure control device controlling braking force of the brake system with reference to at least one of a comparison of the slip speed and the threshold value thereof, and a comparison of the wheel acceleration and the threshold value thereof, whereby skidding of the wheel is prevented by temporarily controlling the braking force.
