The invention relates to a method and a system for operating a steering-by-wire of a motor vehicle, and to a steering-by-wire, comprising a steering rod, a slip-free rotational/translational transmission and an electric motor by means of which the steering rod is moved, and also comprising an electronic control unit for controlling the electric motor, and an electric motor having an energy supply, a storage element, a main controller device and a rotor position sensor, the electric motor having a cogging torque which prevents the steering lever from moving when the electric motor is stopped, when the main controller device is in a shutdown state, the rotor position sensor detects a rotor position as a previous rotor position when it recognizes a point in time at which the electric motor stops operating and transmits it to the storage element for storage and thereby determines a previous spindle position. And when the main controller device is restarted, the main shaft position determined by the stored previous rotor position is used as a reinitialization value in order to determine the current position of the steering rod, and the main shaft position is transmitted to the position adjustment subsequently started by the main controller device.

    用于运行机动车辆的线控转向器的方法和系统以及线控转向器,线控转向器具有转向杆、无滑动的旋转/平移传动装置和借助其使转向杆移动的电马达,还设有操控电马达的电子式控制器,其具有能量供应部、存储元件和主控制器设备和转子位置传感器,电马达具有齿槽扭矩,其防止转向杆在电马达停止运转时发生移动,在主控制器设备置于关机状态下转子位置传感器检测当其识别到电马达停止运转的时间点时的转子位置作为前一转子位置且将其传递到存储元件以进行存储并由此确定前一主轴位置,并且当主控制器设备重新启动时其将由存储的前一转子位置确定的主轴位置用作重新初始化值以便确定转向杆的当前位置,主轴位置被传输到主控制器设备随后启动的位置调节。
