ABSTRACT:
In an anti-skid control apparatus for a four-wheeled vehicle, fluid pressure control valve devices are arranged in the respective brake conduits, and a control unit determines which side of the road has a lower coefficient of friction. This side is called the low side. The fluid pressure control valve device connected to the one front wheel on the low side effects brake relieving control on the basis of the brake relieving signal of the one of the front and rear wheels on the low side which has generated the brake relieving signal sooner than the other. In the alternative, it effects brake relieving control on the basis of the brake relieving signal of the one or ones of the front wheels on the low side of the rear wheels which has generated the brake relieving signal sooner than the other or others.
