Abstract

L'invention concerne un dispositif de commande de dérapage pour véhicules automobiles. Ce dispositif comprend une soupape 72 ouverte pour un freinage normal et fermée pour une commande de dérapage, un piston de détente 58 mobile entre deux positions pour ouvrir et fermer ladite soupape, et des moyens 84, 114 produisant un signal destiné au conducteur uniquement quand le piston 58 est dans une position de commande de dérapage. L'invention permet de faire la distinction entre un signal indiquant le blocage des roues et un signal correspondant à un défaut du système hydraulique.
