Abstract

Ce dispositif comprend un capteur 10 de vitesse d'un roue, un convertisseur fréquence-tension 14 raccordé à un différenciateur 32 dont le signal de sortie, qui représente l'accélération ou la décélération de la roue, est appliqué à une jonction sommatrice 42 qui reçoit également un signal de référence de décélération et qui actionne un interrupteur 44 de commande du modulateur des freins. Une partie du signal de référence est fournie par un circuit de commande << souple >> 70 et, pour le cycle initial, par un circuit 72 qui fournit un signal de référence élevé pour rendre le dispositif insensible aux parasites et qui est commandé par le circuit de commande 70. Le signal du circuit 72 de cycle initial est ainsi maintenu jusqu'à ce qu'une condition de blocage imminent des roues soit détectée même si des parasites provoquent des desserrages prématurés et erronés des freins.
