Abstract

L'invention concerne un procédé pour déterminer une caractéristique de commande d'une soupape hydraulique à commande analogisée ou analogique d'un système de freinage destiné à des véhicules automobiles équipés de freins de roues à actionnement hydraulique. Une pression de freinage (pDBE) générée à l'aide d'un dispositif de fourniture de pression (101, 5) apte à être commandé par voie électrique et entraîné par un moteur électrique (110, 35), aboutit dans un frein de roue (105a, 105b; 8-11) via une soupape d'admission (102a, 102b; 6a-d), et peut être évacuée du frein de roue et cédée à un réservoir de fluide sous pression (104, 4) notamment via une soupape de sortie (103a, 103b, 7a-d). Le fonctionnement du système de freinage implique que le dispositif de fourniture de pression et les soupapes d'admission, et notamment les soupapes de sortie, puissent être commandés par une unité électronique de commande et de régulation (110, 12). La détermination de la caractéristique de commande d'une soupape d'admission ou de sortie à commande analogisée ou analogique par l'intermédiaire de l'unité de commande et de régulation implique la génération d'une pression de freinage au moyen du dispositif de fourniture de pression, et la détermination de la pression de freinage (pDBE) par un capteur de pression (106, 19) associé au dispositif de fourniture de pression. La pression de freinage déterminée et une grandeur (I, U) de commande de soupape associée sont enregistrées comme point d'étalonnage de la caractéristique de commande (f, F). L'invention concerne également un système de freinage.
