Abstract

Système de mesure du couple et de l’angle volant absolu multi tours pour direction de véhicule à l’aide de deux capteurs de position angulaire L’invention concerne un système de détection pour une direction (2) d’un véhicule 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 du côté de la barre de torsion qui est le côté opposé à celui où se trouve le réducteur (4), et délivrant un deuxième signal - et une unité de traitement (15) effectuant une somme pondérée angulaire du premier signal et du deuxième signal pour produire un premier signal calculé ( ) proportionnel à l’angle volant absolu sur plus d’un tour mécanique ( ) et pour produire un deuxième signal calculé ( ) proportionnel au couple (T). Figure pour l’abrégé : Fig. 1.System for measuring torque and absolute multi-turn steering wheel angle for vehicle steering using two angular position sensors The invention relates to a detection system for a steering (2) of a vehicle comprising:- a first angular position sensor (11) measuring the angle of the electric motor (3) and delivering a first signal - a second angular position sensor (12) measuring the angle of the steering on the side of the torsion bar which is the side opposite that where the reducer (4) is located, and delivering a second signal - and a processing unit (15) performing an angular weighted sum of the first signal and of the second signal to produce a calculated first signal ( ) proportional to the absolute steering wheel angle over more than one mechanical revolution ( ) and to produce a second calculated signal ( ) proportional to the torque (T). Figure for abstract: Fig. 1.
