The present invention relates to power assisted Steer by Wire steering system (100) for a vehicle or similar comprising a steering arrangement (1), a steering shaft (2) connected to the steering arrangement (1), steerable elements (13,13), an electrically controllable actuator (8) arranged on or connected to a link arrangement (9) connected to the steerable elements (13,13), an Electronic Control Unit, ECU, (5) controlling the electrically controllable actuator (8) and a feedback arrangement (10) connected to the ECU (5). The feedback arrangement (10) comprises an electric feedback motor (3) and a mechanical feedback arrangement (4). The mechanical feedback arrangement (4) comprises a deformation reactive, clastic arrangement arranged to react on a force produced by the steering arrangement (1) by generation of a reaction force counteracting the force produced by the steering arrangement (1) to provide a mechanical feedback force. The feedback force applied to the steering arrangement (1) comprises a combination of, or the sum of, the mechanical feedback force and an electric feedback force provided by the electric feedback motor (4).
A STEERING SYSTEM, A METHOD FOR PROVIDING STEERING FEEDBACK IN SUCH A SYSTEM AND A STEERING SYSTEM FEEDBACK ARRANGEMENT
