Abstract

Procédé de synchronisation, estimant la position angulaire d'un moteur, modulo un cycle moteur, au moyen d'un capteur vilebrequin (CRK) comprenant un détecteur vilebrequin en regard d'une roue dentée vilebrequin, effectuant deux tours par cycle moteur, et comprenant un grand nombre de dents régulières et au moins un repère, et d'au moins un capteur arbre à cames (CAM), chaque capteur arbre à cames (CAM) comprenant un détecteur arbre à cames en regard d'une route dentée arbre à cames, effectuant un tour par cycle moteur, et comprenant un petit nombre de dents avantageusement irrégulières, caractérisé en ce que le procédé produit un intervalle (IP) continu, contenant ladite position angulaire du moteur.Synchronization method, estimating the angular position of an engine, modulo one engine cycle, by means of a crankshaft sensor (CRK) comprising a crankshaft detector opposite a crankshaft gear, performing two revolutions per engine cycle, and comprising a large number of regular teeth and at least one marker, and at least one camshaft sensor (CAM), each camshaft sensor (CAM) comprising a camshaft detector facing a camshaft toothed road , making one revolution per motor cycle, and comprising a small number of advantageously irregular teeth, characterized in that the method produces a continuous interval (IP), containing said angular position of the motor.
