ABSTRACT:
The present invention comprises a modulator which controls the brake fluid pressure which is provided to the hydraulic systems which extend from the brake fluid pressure source to each wheel, and a controller which controls said modulator. The controller lowers the rate of the increase in brake fluid pressure in one of the wheels on the opposite right or left side of a wheel which is being antiskid controlled, and by thus operating the modulator and maintaining or decreasing brake fluid pressure, relaxes the conditions for the initiation of antiskid control. Concretely, it lowers the threshold values for the slip ratio and the deceleration in the wheel speed, which are used in the decision to initiate antiskid control.
