Abstract
Abstract An anti-skid control for use in an automotive vehicle is comprised of a brake control device for adjusting braking force of each road-wheel of a vehicle, the brake control device being set to be initiated upon receipt of a condition, a detecting device being set to be initiated upon receipt of a condition, a detecting device for measuring a load applied to the vehicle, and a changing device for less sensitivity of the initiation of the brake control device as the load decreases. Even if an instantaneous decrease of the load occurs due to the vehicle's jumping motion or turning motion, an expected initiation of the brake operation can be prevented.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
183 words
An anti-skid control system for use in an automotive vehicle having wheels comprising: braking means operable only upon operation of a brake pedal for applying a braking force to said wheels; speed sensor means and load sensor means operably associated with each wheel; brake control means for independently adjusting the braking force applied to each wheel; initiation slip rate setting means for setting the initiation slip rate for each wheel depending upon load applied to each wheel to determine when initiation of said brake control means is permitted; and prohibit slip rate setting means for setting the prohibit slip rate for each wheel depending on load applied to each wheel to determine when initiation of said brake control means is prohibited; said initiation slip rate setting means and said prohibit slip rate setting means constitute both a brake control initiation sensitivity setting means and a brake control initiation sensitivity changing means, whereby upon decrease of the load during vehicle deceleration, the initiation slip rate and the prohibit slip rate increase which results in poor sensitivity of the initiation of said brake control means.
