Abstract
A method for detecting the position of a rotor element on the basis of a sensor signal of a sensor unit in order to detect a first angular position of the rotor element. The angular position relating to a repeating sub-section of a rotation of the rotor element within a rotational range. A computer program product and a sensor device are also provided.

A method to detecting a rotor position of a rotor element as a function of a sensor signal of a sensor unit to detect a first angular position of the rotor element, which relates to a repeating subsection of a rotation of the rotor element within a rotational range, the method comprising:
- determining the first angular position of the rotor element as a function of the sensor signal;
- sensing a piece of position information for localizing the first angular position within the rotational range;
- ascertaining a piece of error information of an expected angle error as a function of the first angular position and the position information;
- and
- determining the rotor position of the rotor element relating to the rotational range as a function of the error information.
