Abstract

L'invention concerne des mesures de vitesses relatives et sous-cycliques pour les diagnostics des moteurs à combustion interne. Le système de l'invention comprend des capteurs de détection de paramètres de moteur et des conditionneurs de signaux 10, certains de ces capteurs concernant des pressions, des températures et analogues, si bien qu'ils sont des signaux analogiques dont l'amplitude est une mesure du paramètre à détecter. Ces capteurs 10 sont raccordés, via des lignes 13, à un convertisseur analogique-numérique 11 lors d'une sélection par un multiplexeur analogique-numérique 12. Ce système est utilisé pour fournir des indications concernant la vitesse relative d'un moteur sans conversion en dimensions de vitesse.
