The invention relates to an electrically adjustable steering column (1) for a motor vehicle, comprising: a bearing unit (4) which holds a positioning unit (2) in an adjustable manner; an adjusting device (5, 6) which has an adjusting motor (7, 8) and is designed to adjust the positioning unit (2) relative to the bearing unit (4); a mechanical adjustment stop (22, 23) which mechanically limits the adjustment of the positioning unit (2) in the first adjustment direction (40); and a control unit (9). The control unit (9) is designed to activate the adjustment motor (7, 8) and defines a virtual adjustment stop upstream of the mechanical adjustment stop (22, 23) with respect to the first adjustment direction (40). The steering column (1) is designed to adjust the positioning unit (2). In order to adjust the positioning unit (2), the positioning unit (2) is adjusted in a first adjustment direction (40) by means of an adjustment motor (7, 8), and the positioning unit (2) is adjusted beyond a virtual adjustment stop according to a defined first specification. Then, the positioning unit (2) is stopped for reversing the direction, and the positioning unit (2) is adjusted into the holding position against the first adjustment direction (40) according to a defined second specification and then stopped.

    本发明涉及一种用于机动车辆的可电动调节转向柱(1),该可电动调节转向柱包括:支承单元(4),该支承单元以可调节的方式保持定位单元(2);调节装置(5、6),该调节装置具有调节马达(7、8)并且设计成用于相对于支承单元(4)对定位单元(2)进行调节;机械调节止挡件(22、23),该机械调节止挡件机械地限制定位单元(2)在第一调节方向(40)上的调节;以及控制单元(9)。控制单元(9)设计成启用调节马达(7、8),限定有虚拟调节止挡件,虚拟调节止挡件相对于第一调节方向(40)位于机械调节止挡件(22、23)的上游。转向柱(1)设计成对定位单元(2)进行调节。为了调节定位单元(2),定位单元(2)借助于调节马达(7、8)在第一调节方向(40)上被调节,定位单元(2)根据限定的第一规定被调节超过虚拟调节止挡件。然后,定位单元(2)停止以进行方向反转,并且定位单元(2)根据限定的第二规定逆着第一调节方向(40)被调节到保持位置并然后停止。
