Abstract
According to one example implementation, an angle sensor apparatus is provided, including: a sensor arrangement that is configured to respond to a rotational movement of a rotatable object by providing at least two phase-shifted measurement signals, an angle determination device that is configured to take the at least two phase-shifted measurement signals as a basis for determining an angular position, and a difference calculation device that is configured to determine a difference between the angular position determined by the angle determination device and an output from a counter, the counter being configured to be controlled based on the difference.

An angle sensor apparatus, comprising:
- a sensor device that is configured to respond to a rotational movement of a rotatable object by providing at least two phase-shifted measurement signals,
- an angle determination device that is configured to take the at least two phase-shifted measurement signals as a basis for determining an angular position of the rotatable object, and
- a difference calculation device that is configured to determine a difference between the angular position determined by the angle determination device and an output from a counter,
- the counter being configured to be controlled based on the difference between the angular position determined by the angle determination device and the output from the counter.
A method, comprising:
- detecting a rotational movement of a rotatable object and generating at least two phase-shifted measurement signals in response to the rotational movement,
- determining an angular position based on the at least two phase-shifted measurement signals,
- calculating a difference between the determined angular position and an output from a counter, and
- controlling the counter based on the difference between the determined angular position and the output from the counter.
