Abstract

L'invention concerne un procédé et un dispositif correspondant pour allouer des détecteurs (6, 6') d'un type à des objets à mesurer de moteur à combustion interne (1). Les valeurs mesurées des objets à mesurer sont modifiées par des variables de réglage du moteur à combustion interne (1) concerné. Ces modifications sont détectées par des détecteurs (6, 6') dans le cours temporel des valeurs mesurées. L'allocation des détecteurs (6, 6') aux objets à mesurer du moteur à combustion interne (1) s'effectue sur la base des signaux résultant des valeurs mesurées modifiées. Le procédé selon l'invention présente comme avantage de ne pas nécessiter, pour l'allocation, de fiches de détecteurs codées ou de câbles de détecteurs de différentes longueurs. Le nombre de variantes de détecteurs installées se trouve ainsi réduit comparativement aux procédés habituellement utilisés et les frais d'entreposage sont également diminués.
