The invention provides a method of managing the braking of an aircraft having a plurality of brakes comprising friction elements, the method comprising the following steps for at least one group of brakes:

Method of distributing braking within at least one group of brakes of an aircraft

A braking control method that includes: (1) regularly updating a grip model representative of a relationship between a coefficient of friction and a wheel slip rate; (2) determining, with an iterative calculation process including a plurality of calculation cycles a variation of a braking setpoint in a given prediction horizon, the variation of the braking setpoint in the given prediction horizon being established using the regularly updated grip model and its characteristic shape and so that the variation of the braking setpoint in the given prediction horizon complies with the braking order and complies with a given calculation constraint which is function of the wheel slip rate; and (3) retaining as the generated braking setpoint a value of the braking setpoint in the given prediction horizon which corresponds to a first calculation cycle of the plurality of calculation cycles of the iterative calculation process.

Method of adaptive braking control for a vehicle

The invention relates to a method of managing the braking of an aircraft while taxiing on an airport, the method comprising, on the basis of characteristics for a sequence of movements of the aircraft along at least one given path to be followed by the aircraft on the airport, the step of deducing information concerning the braking to be performed so that the aircraft does indeed travel in application of said sequence of movements.

Method of managing the braking of an aircraft by predicting its movements on an airport

A method of distribution braking between the brakes of an aircraft. The method includes a first step of estimating a braking force objective and a steering torque objective to be achieved by the brakes of the aircraft. It also includes the steps of defining at least two groups of brakes () and determining, for each group, a braking level that is to be achieved by the group. The braking levels being calculated in such a manner that braking performed in application of the braking levels is, at least under normal operating conditions of the brakes, in compliance with a braking force objective and with a steering torque objective.
