Verfahren zur Bestimmung eines Position eines sich linear bewegenden Aktorgetriebes in einem Aktorsystem, insbesondere einem Kupplungsbetätigungssystem eines Kraftfahrzeuges und ein Aktorsystem

摘要

The invention relates to a method for determining a position of a linearly moving actuator gear, in particular a clutch actuating system of a motor vehicle, wherein the actuator gear is driven by an electric motor, wherein a position signal of a rotor of the electric motor is received by a sensor. In a method wherein a highly accurate referencing between the path of the actuator gear and the position signal of the rotor of the electric motor is possible despite a soft stop, a sensor designed as an absolute angle encoder measures, as a position signal of the rotor, a current angle, which is allocated in dependence on an initial angle of a rotation of the rotor identified during an initialization process, from which the position of the actuator gear is determined.
