Capteur et méthode de mesure d'un angle de rotation

Drehwinkelsensor und Verfahren zur Ermittlung eines Drehwinkels

Apparatus and method for detecting rotational angle

Abstract

Provided is a method for manufacturing an apparatus and a method for detecting a rotational angle with a high degree of design freedom, which may accurately detect the absolute angle of the rotational axis, and at the same time, readily cope with changes of the rotational axis, number of rotation, and measurement accuracy.    the apparatus (1) for detecting the rotational angle detects the rotational angle of the rotor (4) which is rotatably formed as absolute angle, and comprises a first transmission gear (4A) and a second transmission gear (4B) formed along the rotational axis member (2) of the steering wheel, which have a different pitch circles from each other, a first output gear (5) that rotatably teeth-engages with the first transmission gear (4A) to output a first angle signal based on their rotation, and a second output gear (6) that rotatably teeth-engages with the second transmission gear (4B) to output a second angle signal based on their rotation at the outer peripheral surface of the rotor (4), and detects the absolute angle of the rotor (4) from the first and second angle signals.
