Abstract

Système de freinage antidérapant comportant des premiers moyens pour engendrer un premier signal représentatif de la pression souhaitée dans un moteur de frein et un circuit pour engendrer un second signal représentatif de la pression réelle dans le moteur de frein. Un modulateur est commandé en fonction du résultat de la comparaison des premier et second signaux. Les moyens pour engendrer le second signal comportent un comparateur qui compare un signal représentatif du courant d'actionnement du solénoïde du modulateur, avec un signal de référence. Une capacité sur laquelle est délivrée le deuxième signal est chargée ou déchargée en fonction du niveau du signal de sortie du comparateur.
