Abstract
An antiskid brake system for an automotive vehicle is provided which includes a parameter determining circuit and a braking condition determining circuit. The parameter determining circuit determines a parameter reflecting on brake torque applied to a wheel of the vehicle. The braking condition determining circuit compares the phase of a change in speed of the wheel with the phase of a change in the parameter to determine a phase delay of the change in speed of the wheel and determines the braking condition based on the phase delay, thereby allowing a wheel skid used in the antiskid brake control precisely without employing parameters such as vehicle speed and wheel speed as employed in conventional antiskid brake systems.
