1. Steering system for a vehicle, the steering system comprising:
a steering unit comprising a steering wheel;
a steering-feel unit for generating a steering reaction force when the steering wheel is rotated, and comprising at least one spring coupled to the steering wheel, and an actuator for changing a spring loading and/or spring stiffness of the at least one spring;
a position sensor for measuring an angular position of the steering wheel and/or a speed sensor for measuring a vehicle speed; and
a control unit for controlling the actuator, the control unit operationally coupled to the actuator and to the position sensor and/or the speed sensor,
wherein the actuator is configured to change the spring loading and/or spring stiffness depending on the angular position of the steering wheel and/or the vehicle speed,
wherein the steering unit is mechanically coupled to the steering-feel unit via a coupling mechanism, and
wherein a rotational movement of the steering wheel is converted to a translational movement of the coupling mechanism or a rotational movement of the coupling mechanism.
