Abstract

La présente invention a pour objet un dispositif (9) de détermination de la position d'un axe mobile d'un véhicule automobile comprenant un capteur (10) de position linéaire inductif. Le capteur (10) comprend un circuit imprimé sur lequel est monté un agencement de bobines comportant une bobine primaire (12), une première bobine secondaire (14A) et une deuxième bobine secondaire (14B) de même longueur. Le dispositif (9) comprend un module cible (20) comprenant une première cible (21) et une deuxième cible (22) solidaires en translation réalisées dans un matériau conducteur de résistivité différente, ledit module cible (20) étant configuré pour se déplacer parallèlement au capteur (10) sur au moins la moitié de la longueur de la première bobine secondaire (14A) et de la deuxième bobine secondaire (14B) de sorte qu'au moins l'une de la première cible (21) ou de la deuxième cible (22) soit toujours en regard de la première bobine secondaire (14A) et de la deuxième bobine secondaire (14B).
