Steer unit for steer-by-wire comprising angle sensing means ( 12 ) for detecting the angular position of a steering wheel ( 11 ), processing means ( 10 ) connected to the angle sensing means ( 12 ) and connectable to a wheel position sensor ( 22 ), the wheel position sensor ( 22 ) being arranged for providing an output signal representing the position of steered wheels ( 20 ) of a vehicle. The processing means ( 10 ) are connectable to a steering actuator ( 21 ) mechanically coupled to the steered wheels ( 20 ), the processing means ( 10 ) being arranged for driving the steering actuator ( 21 ) dependent on the angular position of the steering wheel ( 11 ). The steer unit further comprises friction means ( 14 ) for providing a friction force on the steering wheel ( 11 ), the friction means ( 14 ) being connected to the processing means ( 10 ), and the processing means ( 10 ) being arranged for driving the friction means ( 14 ) in dependence of the wheel position sensor output signal.
