Abstract

L'invention concerne essentiellement un capteur (100) inductif de véhicule automobile, comportant : - une bobine d'excitation (101) adaptée à former un champ électromagnétique, - une bobine de mesure (103) de champ magnétique adaptée à fournir un signal de sortie représentatif de la position d'une cible (102) métallique dans le champ magnétique formé par la bobine d'excitation (101), caractérisé en ce qu'il comporte au moins deux circuits électriques (111) branchés simultanément en parallèle sur des bornes de la bobine d'excitation (101), chaque circuit électrique (111) comportant un élément inverseur (112) et un élément capacitif (113), et formant avec ladite bobine d'excitation (101) un oscillateur électrique (110) adapté à former par phénomène de résonance électrique une tension alternative aux bornes de ladite bobine d'excitation (101), lesdits oscillateurs électriques (110) étant de même fréquence de résonance.
