Vehicular brake controlling apparatus and method

Abstract

Road wheel accelerations are calculated in a controller from respective road wheel velocity values. Any one of the road wheel velocities, including the road wheel velocity of one of the road wheels that is a controlled system in an anti-lock brake control during a brake operation, is selected on the basis of a predetermined condition, any one of the road wheel accelerations is selected from among results of calculations of the road wheel accelerations which corresponds to one of the road wheel velocities which is selected so as to generate a control-purpose road wheel acceleration, and anti-lock brake control is executed for each road wheel during the brake operation using the selected road wheel velocity and the control-purpose road wheel acceleration so as to prevent a wheel's lock for each road wheel from occurring.
