Abstract

La soupape proportionnelle (80, 80A, 80B) actionnée par la défaillance d'un système de freinage adaptatif (10) comprend une soupape proportionnelle qui se trouve hors service pendant le fonctionnement normal du système de freinage adaptif. Lorsque le système de freinage adaptatif (10) subit une défaillance, et que, par conséquence, une ou plusieurs roues associées (49, 59) du véhicule ne reçoivent plus une pression de freinage appropriée à partir d'un mécanisme pressuriseur (12) du véhicule, la soupape proportionnelle (80, 80A, 80B) est actionnée par l'unité de commande électronique (70) du système de freinage adaptatif (10) afin que la pression de freinage soit proportionnée en conséquence.
