Abstract
L’invention concerne un procédé d’augmentation d’une résolution d’un capteur magnétique pour moteur thermique de véhicule automobile. Le capteur délivre un signal électrique de synchronisation présentant des créneaux (13) successifs et espacés dont un des fronts ascendants ou descendants correspond à un angle de rotation respectif de l’élément du moteur. Une plage de tension de synchronisation (10) est intercalée entre une plage de modulation de tension supérieure (11) et une plage de modulation de tension inférieure (12) respectivement à la tension supérieure et inférieure de la plage de synchronisation (10), le signal électrique dans chacune des plages de modulation inférieure (12) et supérieure (11) étant modulé pour présenter des créneaux supplémentaires (14) aux créneaux (13) du signal de synchronisation correspondant à des créneaux d’horloge périodiques avec une période dépendant du régime moteur, un angle de rotation étant identifié par un des fronts ascendants ou descendants de chaque créneau supplémentaire (14).
