Abstract

L'invention concerne un système de commande de frein anti-blocage pour véhicule à roues freinées. Le systeme comprend des moyens de captage qui engendrent un signal proportionnel à la décélération/accélération de la roue freinée, des moyens de commutation qui, en réponse à ce signal, causent un relâchement de la pression du frein lorsque la décélération de la roue dépasse un seuil prédéterminé, et des moyens de commande comprenant un dispositif d'accumulation de charge qui fait varier la durée du relachement de pression. Les moyens de commutation comprennent un commutateur capteur de décélération qui engendre une impulsion de relâchement de pression du frein; les moyens de commande comprennent un dispositif d'accumulation de charge qui se charge de façon progressive et prédéterminée tant que l'impulsion de relâchement est engendrée et se décharge à un taux de dégradation prédéterminé. Des moyens de comparaison engendrent une impulsion de relâchement de prolongement en fonction de leurs valeurs relatives, et des moyens permettant de faire varier les potentiels sous la dépendance de l'accélération de la roue au-dessus d'un seuil d'accélération préréglé de sorte que l'impulsion de relâchement de pression du frein prend fin par suite d'un accroissement d'accélération de la roue. Application aux voitures à freins.
