ABSTRACT:
The invention relates to controlling an electrohydraulic braking apparatus of a wheel set in which each wheel is fitted with a brake that is actuated from brake pedals by way of a servo-valve that is electrically controlled by a control unit which measures information relating to the degree of depression of the pedals. According to the invention, when an aircraft is taxiing, braking for the wheels in a first group is organized separately from braking for the wheels in a second group, applied braking pressure varying as a function of brake pedal depression in compliance with respective relationships specific to each of the groups of wheels, which relationships operate over the entire active range of brake pedal depression. One of the two relationships is a continuously increasing function that gives rise to braking torque from a low value of brake pedal depression, while the other relationship is a continuously increasing function that gives rise to braking torque only above a predetermined depression threshold of said pedals.
