A method for controlling a steer-by-wire steering system for a motor vehicle having steerable front and rear wheels in emergency steering operation comprises checking the steering system for the presence of a fault state and performing the emergency steering operation to maintain original driving behaviour if a fault state is detected, including: determining a target lateral acceleration on the basis of a current steering wheel position and a current vehicle speed, determining a yaw moment and, from the yaw moment, a general wheel steering angle for the original driving behaviour, where the general wheel steering angle is equal to a difference between a front wheel steering angle and a rear wheel steering angle, determining a front wheel steering angle correction and a rear wheel steering angle correction, and determining drive torques and/or braking torques for the front wheels and the rear wheels, which are distributed appropriately by the torque vectoring system.
