A method for controlling a steer-by-wire steering system involves determining a torque request signal with a position controller based on desired and actual steering angles, checking with a checking device for an error state of the position controller, selecting the torque request signal as a checked torque request signal if the error state has not been determined, selecting a reference torque signal as the checked torque request signal if the error state has been determined, and transmitting the checked torque request signal to the steering actuator. By evaluating a cumulative deviation variable, which is calculated by a calculation unit of the checking device as a time integral over a control deviation between the desired and actual steering angles, the checking device determines whether the error state is present and determines the reference torque signal with a reference controller based on the control deviation.
