Clutch actuator, detection system and method for detecting an angular position of a rotary component

A method for detecting an angular position of a rotational component rotatable about a rotational axis, the method comprising:

• providing, via a sensor unit, a first sensor signal and a second sensor signal to an evaluation unit, wherein the sensor unit includes a fixed sensor element and a rotational element rotatable relative to the sensor element and jointly with the rotational component, and wherein the first sensor signal is dependent on the angular position, and the second sensor signal is phase-shifted by 90° with respect to the first sensor signal;
• determining, via the evaluation unit, a noise value that is superimposed on each sensor signal due to noise in the corresponding sensor signal;
• then correcting, via the evaluation unit, each sensor signal based on the noise value determined for the corresponding sensor signal;
• determining, via the evaluation unit, highest amplitudes for each of the first and second sensor signals as a maximum value of amplitudes of the respective sensor signals detected over multiple revolutions of the rotational element;
• and
• determining, via the evaluation unit, the angular position based on output from an atan2-function that takes the first and second sensor signals and the highest amplitudes as input.
