The invention relates to a method of controlling a vehicle brake that is adapted to exert a braking force in response to an actuation setpoint, the method comprising the following steps: -from a braking setpoint, determining a nominal actuation setpoint for the brake actuator, taking account of all of the components of the braking setpoint; -from the same braking setpoint, and from a measurement of the torque developed by the brake, determining a correction for the nominal actuation setpoint, this correction taking account only of low-frequency variations in the braking setpoint; and adding the correction to the nominal setpoint.
L'invention concerne un procédé de commande d'un frein de véhicule adapté à exercer un effort de freinage en réponse à une consigne d'actionnement, dans lequel : - à partir d'une consigne de freinage incluant des composantes à basse fréquence et des composantes à haute fréquence, on détermine une consigne nominale d'ac- tionnement de l'actionneur du frein tenant compte de tou- tes les composantes de la consigne de freinage ; - à partir de cette même consigne de freinage, et d'une mesure du couple développé par le frein, on déter- mine une correction de la consigne nominale d'actionne- ment, la correction ne tenant compte que des évolutions de basse fréquence de la consigne de freinage; - on ajoute la correction à la consigne nominale.
