  • Method for operating a steering apparatus of a motor vehicle comprising an electromechanical steering-assistance device
    Patent number: 9296416
    Abstract: A method for operating a steering apparatus of a motor vehicle includes detecting interference-induced vibrations which act on a torsion bar of the steering apparatus and analyzing a frequency and amplitude of the interference-induced vibrations. A steering-stabilization function of the steering-assistance device is activated when a limit value for the amplitude of the interference-induced vibrations is exceeded. A drive signal is provided, with the steering stabilization function, for an electric motor of the steering-assistance device, so that the electric motor generates a compensation torque Mbar which acts on the torsion bar and at least partially counteracts the interference-induced vibrations. An indicator is formed from the frequency and the amplitude of the interference-induced vibrations and the carriageway induced vibrations are distinguished from vibrations caused by instabilities in the steering apparatus.
