Abstract

Commande de frein anti-dérapage à détecteur délivrant un signal proportionnel à l'accélération d'une roue freinée Un commutateur COMP 1 sensible à ce signal engendre des signaux de déclenchement à des niveaux donnés d'accélération de manière à diviser des cycles anti-dérapage successifs en temps d'accélération successifs séparés par des temps intermédiaires, un intégrateur C2 sensible aux signaux de déclenchement engendre un signal de sortie Vc2 qui varie de façon progressive dans un sens pendant chaque temps d'accélération et en sens opposé pendant chaque temps intermédiaire, et un connecteur de sortie X, Y fournit un signal faisant varier un paramètre de commande au sein du système de manière à le caler en fonction des conditions de frottement de la surface.
