Abstract
A method for damping an oscillation of a superimposed steering system of a motor vehicle in which a sensor of the superimposed steering system detects an actual steering angle of a motor of the superimposed steering system and a control device of the superimposed steering system determines an oscillation of the superimposed steering system as a periodic change of the detected actual steering angle and, in the case of a determined oscillation, carries out a measure for damping the oscillation.
Claims7
A method for damping an oscillation of a superimposed steering system of a vehicle, comprising:
- detecting, using a sensor of the superimposed steering system, an actual steering angle of a motor of the superimposed steering system,
- determining an oscillation of the superimposed steering system as a periodic change of the detected actual steering angle by counting a number of periods or semi-periods of the periodic change, and
- upon a determined oscillation, executing a measure for reducing the oscillation as a function of a period number or semi-period number of the periodic change, when the number of periods or the number of semi-periods reaches or exceeds a predetermined actuation value, wherein the measure for reducing oscillation comprises supplying the motor with a control current opposed to the oscillation.
