Abstract

Une chute brutale de la vitesse d'un véhicule ou un bruit anormal peuvent être provoqués par un accroissement subit du coefficient de frottement qui peut se produire lorsque le véhicule est sur le point de s'arrêter, immédiatement après avoir été lavé ou tôt le matin, en hiver. Afin d'éviter cette chute brutale de la vitesse, on cherche à déterminer si le véhicule est sur le point ou non de s'arrêter et si un accroissement subit du coefficient de frottement de l'élément de friction du frein se produit ou non. Lorsqu'un accroissement subit du coefficient de frottement ν de l'élément de friction est détecté, la pression hydraulique appliquée au frein est réduite.
