BRAKE CONTROL SYSTEM FOR AN AUTOMOTIVE VEHICLE

摘要

A brake control system has a means for determining wheel r.p.m., a means for determining acceleration ratio of the wheel r.p.m. and generating a signal when the determined acceleration ratio becomes equal to or more than a predetermined value, a means for determining target wheel r.p.m. based on the wheel r.p.m. and being operatively responsive to detecting of the peak of friction coefficient, and a control means for controlling applying and releasing of pressure fluid to wheel cylinders for skid controlling the wheel deceleration ratio. The target wheel r.p.m. determining means determines ratio of deceleration of wheel r.p.m. based on the difference of wheel r.p.m. between the time detecting the peak of friction coefficient and the time detecting immediate preceding peak and the length of period between detecting of the peaks and thereby determining the target wheel r.p.m. by subtracting a deceleration value obtained based on the determined ratio of deceleration from the wheel r.p.m. determined at the time of detecting of the peaks of friction coefficient.
