Abstract
An automatic control system for a friction-encumbered signaling device (50) in a motor vehicle with the system including a first automatic controller (10) that compares an actual signaling-device position (UI) to a desired signaling-device position (US), with the first automatic controller being capable of calculating at least one input variable for the two-step action controller (40) that is connected to the load side of the first automatic controller, and the two-step action controller (40) including the capability for determining a variable hysteresis width E which is dependent upon system operating parameters.
