1. A steer-by-wire system for a vehicle, the steer-by-wire system comprising:
a steering wheel;
a feedback actuator connected to the steering wheel;
a detection device equipped to detect a driver's intention to enter the vehicle and/or a driver's intention to exit the vehicle; and
an electronic control system, which, following detection of the intention to enter the vehicle and/or the intention to exit the vehicle, is equipped to electrically control the feedback actuator to hold the steering wheel in a predetermined rotational position by generating a holding torque, wherein when an actuating torque which exceeds the holding torque is applied manually to the steering wheel and the steering wheel is consequently rotated out of the predetermined rotational position, the electronic control system is equipped to continuously approximate a turning angle of the predetermined rotational position to a turning angle of a current rotational position of the steering wheel using a specified time-based adjustment function on the basis of a difference between the actuating torque and the holding torque.
