Abstract

Circuit de compensation (42) d'un capteur de vitesse de lacet (38) comprenant une première unité d'exploitation (72, 76) générant un signal de compensation en quadrature (73) en tenant compte d'une valeur de différence ou de somme formée à partir d'une première valeur de mesure (621) et d'une seconde valeur de mesure (622). Le circuit de compensation (42) comporte une seconde unité d'exploitation (86) générant un signal de compensation des vibrations (99) en tenant compte d'une valeur de somme ou de différence (90) entre la première valeur de mesure saisie (621) et la seconde valeur de mesure saisie (622).
