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.
Claims10
A method for damping an oscillation of a superimposed steering system of a vehicle, comprising:
- a sensor of the superimposed steering system detects an actual steering angle of a motor of the superimposed steering system,
- a control device determines an oscillation of the superimposed steering system as a periodic change of the detected actual steering angle and upon a determined oscillation it carries out a measure for reducing the oscillation, and
- wherein the control device carries out the measure as a function of a period number or semi-period number of the periodic change.
A control device for a superimposed steering system of a vehicle, comprising:
- a sensor of the superimposed steering system detects an actual steering angle of a motor of the superimposed steering system,
- a control device determines an oscillation of the superimposed steering system as a periodic change of the detected actual steering angle and upon a determined oscillation it carries out a measure for reducing the oscillation, and
- wherein the control device carries out the measure as a function of a period number or semi-period number of the periodic change, which is configured to determine an oscillation of the superimposed steering system as a periodic change of an actual steering angle of a motor of the superimposed steering system which motor is connected to the control device, and which is configured to carry out, upon a determined oscillation as a function of a period number or semi-period number of the periodic change, a measure against the oscillation.
A superimposed steering system, comprising:
- a sensor of the superimposed steering system detects an actual steering angle of a motor of the superimposed steering system,
- a control device determines an oscillation of the superimposed steering system as a periodic change of the detected actual steering angle and upon a determined oscillation it carries out a measure for reducing the oscillation, and
- wherein the control device carries out the measure as a function of a period number or semi-period number of the periodic change
- a control device, a motor connected to the control device and comprises a sensor connected to the control device for detecting an actual steering angle of the motor, in which the control device is configured to determine an oscillation of the superimposed steering system as a periodic change of the actual steering angle detected by the sensor and, if an oscillation is determined as a function of a period number or of a semi-period number of the periodic change, to carry out a measure against the oscillation.
