Method and device for determining and / or controlling a position of an electric motor, in particular in a clutch actuation system of a motor vehicle

摘要

The invention relates to a method for determining and / or controlling a position of an electric motor, in particular in a clutch actuation system of a motor vehicle, wherein the position of a rotor of the electric motor (14) from a, arranged outside a rotational axis of the electric motor to a stator of the electric motor sensor is, wherein the removed from the sensor position signal is evaluated by an evaluation unit. In a method in which a very high position resolution of the rotor of the electric motor is ensured, the position signal output by the sensor system during a sinusoidal drive of the electric motor is plausibilized by means of at least one position signal detected during a block drive of the electric motor.
