Abstract

L'invention concerne un comparateur destiné au circuit de régulation d'un système de direction automatique. Ledit comparateur comporte deux palpeurs qui explorent soit une seule ligne directrice commune, soit deux lignes parallèles, de façon qu'il établisse comme grandeur d'entrée du régulateur la différence à partir de trois grandeurs, à savoir les deux signaux de sortie des palpeurs qui sont fonction des écarts par rapport à la ou les lignes directrices et une grandeur de réglage auxiliaire transmise mécaniquement par la direction du véhicule. Application aux circuits de régulation d'un mécanisme de direction automatique d'un véhicule, notamment d'un véhicule agricole.
