A method and system for rack-and-pinion position adjustment for a steer-by-wire steering system for a motor vehicle. A module provides adjustment of the rack-and-pinion position, by determining a position error from a difference between desired and estimated value(s) of the rack-and-pinion position and the rack-and-pinion speed in a feedback structure, from which a control variable is determined for controlling the rack-and-pinion and a disturbance variable compensation for the control variable is carried out in a feedforward structure by means of a rack force estimation.
