A sensor system for determining an absolute rotational angle of a shaft, a method for determining an absolute rotational angle of a shaft, and a vehicle having a sensor system

摘要

The present invention relates to a sensor system (1) for determining an absolute rotation angle (?) Of a shaft (10) having a rotation angle range of more than one wheel, and a method and a vehicle equipped with the sensor system The main rotor 1 is provided with a main rotor 2 which can be connected to the shaft 10 in a synchronously rotatable manner, a first auxiliary rotor 3 mechanically coupled to the main rotor 2, A first sensor device SE1 which is attached to the first auxiliary rotor 3 to generate a first sensor signal depending on the rotation angle of the first auxiliary rotor 3, A second sensor device SE2 which is attached to the second auxiliary rotor 4 to generate a second sensor signal which depends on the rotation angle of the auxiliary rotor 4, a second sensor device SE2 which is attached to the main rotor 2, A third sensor device SE3 used to generate a third sensor signal that depends on the relative rotational angle y of the main rotor 2, And an evaluation device for determining the absolute rotation angle [delta] of the sensor devices SE1, SE2, SE3 from the sensor signals of the sensor devices SE1, SE2, SE3. The detection range [alpha] of the third sensor device is smaller than 360 [deg.].
