Abstract
Système de freinage anti-dérapage à mémoire incorporée La mémoire enregistre une pression mémorisée fonction de la pression de freinage au point de dérapage de manière à former une information définissant un point de commutation entre une première et une seconde étape de rétablissement de freinage. La seconde étape consiste à poursuivre le rétablissement de la pression avec un taux réduit d'accroissement de pression, la pression mémorisée étant utilisée directement pour commander le fonctionnement des moyens de soupapes pendant la première étape du rétablissement de la pression. Application au freinage anti-dérapage des véhicules.
