1. A method for operating a steer-by-wire steering system of a motor vehicle having at least one steering function, an arbitration unit, and an actuator, the method comprising:
requesting, by the at least one steering function of the steer-by-wire steering system, one or more steering angle changes for at least one vehicle axle;
weighting, by the arbitration unit (AE), the one or more steering angle changes as target steering angles (SLw_i);
determining a selected target steering angle (G_SLw), taking into account at least one of the target steering angles (SLw_i);
determining that a gradient of the selected target steering angle (G_SLw) is smaller than or equal to a gradient of the at least one of the target steering angles (SLw_i) taken into account; and
setting, by the actuator of the steer-by-wire steering system, the selected target steering angle (G_SLw) for the at least one vehicle axle.
