  • Publication number: 20080201025
    Abstract: 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 (12, 13) of brakes: estimating an energy level (?E) to be dissipated by the brakes of the group; and estimating individual braking setpoints (Fi) for each of the brakes of the group so that the individual braking setpoints make it possible, at least under normal operating conditions of the brakes, to implement braking that dissipates said energy level, the individual braking setpoints also being determined so as to satisfy at least one other given operating objective.

  • Publication number: 20080154471
    Abstract: The invention provides a braking control method for a vehicle having a plurality of wheels fitted with tires and with brakes, the control method including generating a braking setpoint for each wheel in response to a braking order, and comprising the following steps for each wheel: regularly updating a grip model Ca/C0=fq1, . . . qn (?) representative of a relationship between a coefficient of friction and a wheel slip rate; using the regularly rest grip model and its characteristic shape to establish in a given prediction horizon, the variation for the braking setpoint that, while complying with the braking order and predictable variation therein during the prediction horizon, also complies with a given calculation constraint; and retaining as the value for the braking setpoint a value of the variation as determined in this way that corresponds to a first calculation cycle in the prediction horizon.
