Abstract
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.
