Abstract
A steer-by-wire system for a land vehicle, having a steering wheel, a feedback actuator, 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 controls the feedback actuator to hold the steering wheel in a predetermined rotational position by generating a holding torque. When an actuating torque which exceeds the holding torque is applied manually to the steering wheel and the steering wheel is rotated out of the predetermined rotational position, the electronic control system continuously approximates 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 based on a difference between the actuating torque and the holding torque.
