Abstract
An antiskid brake controller, which can secure safety by avoiding a cascade caused when a braking pressure is reduced in a four-wheel-drive vehicle, includes wheel speed sensors braking force adjuster for adjusting a braking pressure and an ECU for calculating the control amount of a breaking force adjuster so as to prevent the locking tendency of each of the wheels based on a wheel speed Vw. The ECU includes means for the wheel deceleration calculator Gw corresponding to the locking tendency of each of the wheels, a basic vehicle calculator speed, a slip amount calculator SL based on the wheel speed Vw and the basic vehicle speed, cascade determination device for determining the occurrence of the cascade state when an unstable state occurs such that the slip amounts of three wheels are larger than a predetermined value and control amount corrector for changing the control amount of the braking pressure in an increasing pressure reduction amount when the occurrence of the cascade is determined.
