Abstract
A method for operating a steer-by-wire steering system for a vehicle having at least one steerable wheel. The method including: providing a predefined steering ratio characteristic curve, recording a first steering input value of the steering input variable, providing a magnified characteristic curve that defines a bijective relationship between the steering input variable and the steering output variable, in a magnified region around the first steering input value, forming a modified steering ratio characteristic curve on the basis of the predefined steering ratio characteristic curve, recording a second steering input value of the steering input variable, and determining a steering output value in order to drive the steerable wheel on the basis of the second steering input value and the modified steering ratio characteristic curve. The predefined steering ratio characteristic curve, in the magnified region around the first steering input value, is replaced by the magnified characteristic curve.
