Abstract

The disclosure relates to an apparatus and a method for adapting control of a brushless electric motor in order to influence a position of an actuator, wherein at least two values of an output variable of a sensor are recorded in order to determine a position of the actuator, an item of information relating to the position of the actuator is determined on the basis of the at least two recorded values, the determined information relating to the position of the actuator is assigned to an item of information relating to a rotor position of the electric motor, wherein the at least two recorded values are recorded at two different times in a predefined interval of time, and wherein a duration of the predefined interval of time is determined on the basis of a characteristic of the electric motor.
