The invention relates to an electrically adjustable steering column for a motor vehicle, comprising: an actuation unit on which a steering wheel can be arranged; a support unit by means of which the actuating unit is held in an adjustable manner; and an adjusting device designed to adjust the actuating unit relative to the supporting unit, and comprising an electric motor (55) for adjusting the actuating unit. The steering column also has a control unit (8) which is designed to start the electric motor (55). The control unit (8) is further designed to generate a first signal (S1) and a second signal (S2) in order to start the electric motor (55), the start of the electric motor (55) requiring the application of the first signal (S1) and the second signal (S2), in particular to a first switching unit (12) and a second switching unit (13) of the control unit (8), said switching units being connected in series to the electric motor (55). The invention also relates to a method for operating such a steering column.

    本发明涉及一种用于机动车辆的可电动调节的转向柱,转向柱包括:致动单元,在致动单元上可以布置有方向盘;支承单元,致动单元借助于支承单元以可调节的方式保持;以及调节装置,调节装置设计成相对于支承单元调节致动单元,并且调节装置包括电动马达(55)以便调节致动单元。转向柱还具有控制单元(8),所述控制单元(8)设计成启动电动马达(55)。控制单元(8)还设计为生成第一信号(S1)和第二信号(S2)以便启动电动马达(55),其中,电动马达(55)的启动需要施加第一信号(S1)和第二信号(S2),特别是向控制单元(8)的第一开关单元(12)和第二开关单元(13)施加第一信号和第二信号,所述开关单元串联连接至电动马达(55)。本发明还涉及一种用于操作这种转向柱的方法。
