Abstract
A method for operating a motor-adjustable steering column may be employed by a motor vehicle with an actuating unit supported by a supporting unit. A steering spindle may be rotatably supported in the actuating unit. The actuating unit may be adjustable relative to the supporting unit by means of at least one adjustment drive. The adjustment drive is controlled by a control unit, and the adjustment speed caused by the adjustment drive is determined based on measurement data of a sensor. The control unit controls the adjustment drive in a control loop based on a control deviation between a specifiable speed profile and the determined adjustment speed.
