Abstract
A method for operating an actuator arrangement for a clutch operating system includes providing an actuator arrangement with a transmission, a piston, and an inductive sensor device. The transmission has an electric motor and a metal lead screw that converts a rotary motion into a linear motion. The piston is connected to the metal lead screw. The method also includes energizing the electric motor to linearly displace the metal lead screw in an axial direction, axially displacing the piston with the metal lead screw, using the metal lead screw as a target for the inductive sensor device, and using the inductive sensor device to determine an axial distance traveled by the piston.
