Abstract:
A vehicular brake controlling apparatus comprising:a brake unit arranged to enable an independent control of braking liquid pressures for respective wheel cylinders to brake their corresponding road wheels of the vehicle; a plurality of road wheel velocity sensors to detect respective wheel velocities of the road wheels of the vehicle, the road wheels being front left and right and rear left and right road wheels; and a controller, the controller including: a road wheel acceleration calculating section to calculate road wheel accelerations of the respective road wheels from respective road wheel velocity values detected by the road wheel velocity sensors; a road wheel velocity select processing section to select any one of the road wheel velocities including the road wheel velocity of one of the road wheels that is an object to be controlled in an anti-lock brake control during a brake operation on the basis of a predetermined condition, the selected road wheel velocity serving as a control-purpose road wheel velocity; a control-purpose road wheel acceleration generating section to select any one of the road wheel accelerations from among results of calculations of the road wheel accelerations by means of the road wheel acceleration calculating section which corresponds to one of the road wheel velocities which is selected by the road wheel velocity select processing section so as to generate a control-purpose road wheel acceleration; and an anti-lock brake controlling section to execute the anti-lock brake control for each road wheel through the brake unit during the brake operation using the control-purpose road wheel velocity and the control-purpose road wheel acceleration so as to prevent a wheel's lock for each road wheel from occurring.
