Abstract

L'invention concerne un système et un procédé de commande d'un système de freinage anti-blocage dans un véhicule à moteur, le freinage anti-blocage étant effectué par un système de freinage électronique qui comprend un circuit de commande à modulation d'impulsions en durée connecté à un solénoïde (30) dans une vanne (20) de modulation. La vanne de modulation commande l'air envoyé par une source (12) d'air sous pression dans un cylindre de frein. Le circuit (100) de commande à modulation d'impulsions en durée permet au solénoïde de régler avec précision la pression dans le cylindre de frein lors de l'opération de freinage pour régler la souplesse des profils de courant et de force. Lors d'une opération de commande en régime permanent du système, une diode (146) dans le circuit de commande est connectée en parallèle au solénoïde. Lorsqu'une dissipation rapide se produit, la diode est éliminée du circuit grâce à l'ouverture du circuit de commande avec un système (44, 120) de commutation haute pression et basse pression. Cette opération garantit des performances optimales du circuit de commande lorsque le système de freinage électronique se trouve soit en mode de régime permanent soit en mode de dissipation rapide.
