Abstract

A control unit controls a functional device of a motor vehicle. The control unit has a rotary adjuster that is mounted in a rotatable manner on a holding element. The rotary adjuster has at least one encoding element, a detecting device for detecting an absolute angle of rotation between the rotary adjuster and the holding element with reference to an encoding of the at least one encoding element and a latching device and the rotary adjuster is provided with a plurality of latching positions along a direction of rotation by the latching device. The detecting device is embodied so as with reference to the encoding of the at least one encoding element to detect the respective latching position and the absolute angle of rotation between at least two of the latching positions.
