Abstract
The present invention relates to vehicle steering system arrangement (100) comprising a vehicle suspension allowing wheels to be steered and power assisted vehicle steering with a feedback torque actuator (130), the steering feel being controlled by means of a torque and/or angle control system, TAC, (132). The vehicle suspension with steerable wheels comprises a plurality of vehicle suspension parameters and the geometry and/or dimensions of one or more of the vehicle suspension parameters or elements is/are designed to reduce or minimize the steering force required for steering the vehicle in driving. The torque and/or angle control, TAC, (132) is used for, based at least on directly or indirectly sensed and/or calculated steering wheel angle, controlling the wheel steer angle and providing feedback control by controlling the feedback torque actuator to generate a target feedback torque, and a target steering feel, and hence reducing or eliminating driver feedback provided by the vehicle suspension, such that the steering effort, if there is a fault in the steering control so that the assistance is lost, will be low enough for the driver to handle safely, hence without needing fa…
