A method is disclosure for operating a steer-by-wire vehicle steering system with a steering wheel in a shut-down state of the vehicle. According to one step of the method, after the vehicle has been shut down a procedure is carried out to monitor whether the steering wheel of the vehicle is being moved. If a movement of the steering wheel is ascertained and the movement exceeds a defined first limiting value, the movement of the steering wheel is damped by a damping unit of the steering system. If no movement of the steering wheel exceeding the first limiting value was ascertained for a defined time period, no further monitoring of a movement of the steering wheel and no further damping of the movement of the steering wheel are undertaken, so long as the vehicle is shut down. If, alternatively or additionally, a movement of the steering wheel exceeds a second limiting value, which is lower than the first limiting value, but does not exceed the first limiting value was ascertained within the defined time period and it is ascertained on the basis of an evaluation of the movement profile of the movement of the steering wheel that the movement was not caused by a user, likewise no further monitoring of a movement of the steering wheel and also no further damping of the movement of the steering wheel are undertaken, so long as the vehicle is shut down. Moreover, a steer-by-wire steering system for a vehicle is specified.
