Abstract

The present invention relates to a system and a method for controlling a feedback torque actuator in a steering system. The steering system comprises a steering assistance actuator (140) with a torsion bar (128) and a feedback torque actuator (130) with an Electric Control Unit, ECU, for giving feedback to a driver, a steering wheel (120) to which the driver applies a driver torque, TD. Only the torsion bar of the steering assistance actuator (140) comprises a torsion-bar torque sensor, and a target torque for the feedback torque actuator (130) is a target steering feel torque compensated for torque sensed in the torsion bar (128).
