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 first sensor signal is dependent on the angular position and is associated with a first detection position, and the second sensor signal is associated with a second detection position lying about the rotational axis perpendicular to the first detection position;
• converting, via the evaluation unit, an orthogonal error into an amplitude difference between respective amplitudes of the first and second sensor signals based on a coordinate transformation of the first and second sensor signals;
• adjusting, via the evaluation unit, each of the first and second sensor signals based on the amplitude difference;
• determining, via the evaluation unit, the angular position based on output from an a tan 2-function that takes the adjusted first and second sensor signals as input;
• determining, via the evaluation unit, a common phase shift of the first and second sensor signals, wherein the phase shift is determined after applying the a tan 2-function;
• and
• adjusting, via the evaluation unit, the angular position based on the phase shift.
