Abstract

Brake pressure is varied briefly by means of pressure pulses at regular intervals during phases when brake pressure is otherwise maintained constant, and any variations in transverse acceleration at each axle are determined. These variations at the axles are used to modify the wheel slip by varying the brake pressure in order to increase stability while retaining an adequate steerability reserve or vice versa.
