ABSTRACT:
The pressure increase of the brake hydraulic pressure starts again at a time point where the wheel speed, which has been decelerated due to an increase in the brake hydraulic pressure, recovers the speed due to the subsequent pressure decrease and holding of the brake hydraulic pressure and reaches the speed (Vv-Vx) which is lower than the computed vehicles speed Vv by a predetermined value .DELTA.Vx, where the predetermined value .DELTA.Vx varies in accordance with the magnitude of the friction coefficient of the road surface.
