Abstract
A method for monitoring a motor unit is provided. The method includes: detecting a starting rotor position: ascertaining a non-safety-critical position tolerance range; ascertaining a position offset for the rotor as a function of the ascertained position tolerance range; ascertaining a target rotor position for the rotor based on the starting rotor position and the position offset; specifying a target control pattern based on the ascertained target rotor position; generating and applying a motor control pattern to the motor unit to rotate the rotor to the specified target rotor position using the target control pattern; detecting an actual control pattern controlling the motor unit at an interface between the motor controller and the motor unit; detecting an actual rotor position resulting from the rotation of the rotor using the motor control pattern; and feeding back both the detected actual control pattern and the detected actual rotor position for verification thereof.
