Abstract

Equipement de régulation antiblocage, comportant des moyens de commutation qui, dans des conditions particulières prédéterminées, produisent une sélection en parallèle des organes de commande de la pression, en tenant compte du signal de sélection présent dans un canal de régulation. Des moyens il contrôlent le fonctionnement des capteurs 1, 2 et délivrent un signal en cas de dérangement d'un capteur. Des moyens 15, 16 bloquent les signaux de sortie du canal de régulation affecté au capteur défectueux. En présence d'un signal de dérangement, des moyens de commutation 20, 22 sélectent en parallèle les deux organes de commande de la pression 5, 6 ou 7, 8 à l'aide des signaux de commande du canal de régulation non perturbé. Des opérateurs temporels prolongent pour les deux freins de roue, après le couplage en parallèle, la phase de réduction de pression et le cas échéant la phase suivante à pression constante.Anti-lock regulation equipment, comprising switching means which, under specific predetermined conditions, produce a parallel selection of the pressure control members, taking into account the selection signal present in a regulation channel. Means it control the operation of the sensors 1, 2 and deliver a signal in the event of a sensor fault. Means 15, 16 block the output signals of the regulation channel assigned to the defective sensor. In the presence of a fault signal, switching means 20, 22 select in parallel the two pressure control members 5, 6 or 7, 8 using the control signals of the undisturbed regulation channel. Time operators extend the pressure reduction phase for both wheel brakes after parallel coupling and, if necessary, the following phase at constant pressure.
