Abstract

L'invention concerne un système de détection pour direction comportant : - un premier capteur de position angulaire (11) mesurant l'angle du moteur électrique (3) et délivrant un premier signal ; - un deuxième capteur de position angulaire (12) mesurant l'angle de la direction située entre le réducteur (4) et un premier côté de la barre de torsion (7), et délivrant un deuxième signal ; - un troisième capteur de position angulaire (13) mesurant l'angle de la direction situé d'un deuxième côté de la barre de torsion (7) et délivrant un troisième signal ; - et une unité de traitement (15) effectuant d'une part, un calcul de Vernier sur la base du premier et du deuxième signal pour produire un premier signal calculé (θ 2) proportionnel à l'angle volant absolu sur plus d'un tour mécanique (θ 2) et d'autre part, une somme pondérée angulaire du troisième signal et de l'un des signaux pris parmi, le premier signal, le deuxième signal et le premier signal calculé (θ 2), pour produire un deuxième signal calculé (T) proportionnel au couple (T).
