Abstract
An apparatus for preventing a brake force from increasing in excess upon starting of an anti-lock brake control for enhancing initial brake performance of an anti-lock brake control system. Rotation speed of each of wheels is detected, and wheel acceleration is determined. Further, a corrected acceleration is determined by correcting the wheel acceleration with a torsion torque detected from a driving shaft. In dependence on the statuses of the wheel acceleration and the corrected acceleration, a rate at which the brake force is increased is modified. Enhanced brake performance in the initial control phase can be ensured when the motor vehicle is running on a road exhibiting high friction coefficient while stability of the motor vehicle running on a road of low friction can be realized. Besides, even when difference frictions act on left and right wheels, the motor vehicle is protected against yawing moment.
