1. A method for operating a steering system comprising at least one wheel steering angle adjuster, the method comprising:
influencing and/or changing a wheel steering angle of at least one vehicle wheel depending on a target specification signal correlated with a steering specification using the at least one wheel steering angle adjuster, wherein the at least one wheel steering angle adjuster has a limited maximum wheel steering angle adjustment range for changing the wheel steering angle;
limiting the target specification signal based on saturation to the limited maximum wheel steering angle adjustment range; and
modifying the target specification signal, such that the modified, target specification signal has a constant and differentiable curve at least in an edge range of the limited maximum wheel steering angle adjustment range.
