The invention relates to a method for operating a steer-by-wire system of a motor vehicle, according to which a steering command input via a steering control device is acquired, a control signal for a steering gear actuator is generated by means of an adjusting control unit depending on the steering command, the steering gear actuator is mechanically separated from the steering control device, and an actuating signal is generated by means of the adjusting control unit and is used for exciting a force feedback actuator associated with the steering control device to apply haptic feedback on the steering control device. The method according to the invention is characterized in that at least one natural frequency of the steering control device is determined, and the control signal generated by means of the control unit is coordinated with the determined at least one natural frequency, so that excitation in the natural frequency range of the steering control device is avoided.

    本发明涉及一种用于运行机动车的线控转向系统的方法,根据该方法获取经由转向操纵装置输入的转向命令,借助调节控制单元根据该转向命令生成用于转向传动机构执行器的控制信号,该转向传动机构执行器与转向操纵装置机械分离,借助调节控制单元生成操控信号,该操控信号用于激励配设给转向操纵装置的力反馈执行器以在转向操纵装置上施加触觉反馈。本发明方法的突出之处在于,确定转向操纵装置的至少一个固有频率,使借助调节控制单元生成的操控信号与所确定的至少一个固有频率相协调,从而避免在转向操纵装置的固有频率范围内的激励。
