Abstract
(EN)
Disclosed is a device for detecting an angle of rotation, in which a first angle of rotation calculation section (21) calculates a first angle of rotation (θ1) corresponding to the angle of rotation of a rotor (1), in accordance with an output signal (V1) of a first magnetic sensor (11) and an output signal (V2) of a second magnetic sensor (12). A second angle of rotation calculation section (22) calculates a second angle of rotation (θ2) corresponding to the angle of rotation of the rotor (1), in accordance with the output signal (V2) of the second magnetic sensor (12) and an output signal (V3) of a third magnetic sensor (13). An angle of rotation selection section (23) obtains the final angle of rotation (θ) using the first angle of rotation (θ1) and the second angle of rotation (θ2).

L'invention concerne un dispositif de détection d'un angle de rotation, comportant une première section de calcul d'angle de rotation (21) qui calcule un premier angle de rotation (θ1) correspondant à l'angle de rotation d'un rotor (1), selon un signal de sortie (V1) d'un premier capteur magnétique (11) et un signal de sortie (V2) d'un second capteur magnétique (12). Une seconde section de calcul d'angle de rotation (22) calcule un second angle de rotation (θ2) correspondant à l'angle de rotation du rotor (1), selon le signal de sortie (V2) du second capteur magnétique (12) et un signal de sortie (V3) d'un troisième capteur magnétique (13). Une section de sélection d'angle de rotation (23) obtient l'angle final de rotation (θ) au moyen du premier angle de rotation (θ1) et du second angle de rotation (θ2).
