METHOD AND DEVICE FOR OPERATING A STEERING MECHANISM OF A MOTOR VEHICLE, AND CONTROL UNIT AND STEERING MECHANISM

The invention relates to a method for operating a steering mechanism (12) of a motor vehicle, wherein a steering rod (27) can be held or moved along its longitudinal axis a by means of an electric motor (22) such that the wheel steering angle (8, 9) of at least one wheel (5, 6) of at least one vehicle axle (1) can be maintained or varied. In the event of a force Fext acting substantially axially on the steering rod (27), movement of the steering rod (27) is at least inhibited by means of a detent torque RM of the electric motor (22) and/or a self-induced torque Msip of the electric motor. The invention also relates to a device for carrying out the method and a steering mechanism which is preferably designed as a steer-by-wire steering mechanism. A control unit is provided for carrying out the method. 本发明涉及一种用于操作机动车辆的转向器(12)的方法，其中转向杆(27)能够借助电动马达(22)沿着转向杆的纵向轴线(a)保持或者移位，从而使得至少一个车桥(1)的至少一个车轮(5，6)的车轮转向角(8，9)能够被保持或者移位。在基本上轴向地作用到转向杆(27)上的力(Fext)的情况下，借助于电动马达(22)的卡锁力矩(RM)和/或电动马达的自感力矩(Msip)至少对转向杆(27)的移位进行制动。此外，本发明涉及一种用
