Problems solved by technology

[0012] In this solution, however, rapid successive counter-adjustments of the steering angle can be mistakenly identified as disturbing oscillations, so that the measures to counteract the oscillations themselves are perceived as disturbing.

Abstract

The invention relates to a method for damping oscillations of a superposition steering system of a vehicle, in which method a sensor of the superposition steering system detects the actual steering angle of a motor of the superposition steering system, and a controller of the superposition steering system Periodic changes in the detected actual steering angle are identified as oscillations of the superposition steering system, and measures for reducing the oscillations are carried out for the identified oscillations.

Description

technical field [0001] The invention relates to a method for damping oscillations of a superposition steering system of a vehicle. In the method, a sensor of the superposition steering system detects the actual steering angle of a motor of the superposition steering system, and a controller converts the detected actual Periodic changes in the steering angle are detected as oscillations of the superposition steering system, for which oscillations are determined measures are taken to reduce the oscillations. The invention also relates to a controller for a superposition steering system and a superposition steering system with the controller. Background technique [0002] The steering system of the vehicle is used to determine the direction of travel by steering during driving, that is to say the rotation of the wheels about a vertical pivot axis. For this purpose, the steering system of a vehicle usually includes a steering gear that applies torque to the steered wheels, usua...
