1. A method of controlling a steering rack position based on a steering wheel position in a steer-by-wire system of a vehicle, the method comprises:
obtaining a vehicle speed and the steering wheel position;
calculating a steering rack position value using a steering map based on the vehicle speed and the steering wheel position, wherein:
the steering map comprises tunable steering wheel limits, each being smaller than or equal to an absolute steering wheel limit, and tunable steering rack limits, each being smaller than or equal to an absolute steering rack limit, and
the tunable steering wheel limits and the tunable steering rack limits differ for different combinations of the vehicle speed; and
changing the steering rack position based on the steering rack position value.
