The present embodiments may provide a steer by wire type steering apparatus including a screw shaft rotating in conjunction with the steering shaft, a moving member coupled to an outer circumferential side of the screw shaft and moving in the axial direction when the screw shaft rotates, a housing in which the screw shaft and the moving member are embedded, and a guide member coupled to the housing to support the moving member and guide the axial movement of the moving member.

The disclosure relates in general to methods for operating a vehicle including an electronic steering system and to electronic steering systems for a vehicle. An example method for operating a vehicle including an electronic steering system includes determining an expected value, associated with a steering wheel parameter, comparing a detected steering wheel parameter with the expected value, and if the detected steering wheel parameter exceeds the expected value, triggering at least one compensation measure so that a change in a road wheel angle of a steerable road wheel of the vehicle towards a target road wheel angle is damped.

A control device for an electric power steering (EPS) system may include a first steering controller including a first inverter, a first locking circuit connected to the first inverter, and a first gate driver controlling driving of the first inverter, and a second steering controller including a second inverter, a second locking circuit connected to the second inverter, and a second gate driver controlling driving of the second inverter. If the first steering controller operates normally, the first steering controller may transmit a second lock disable signal for inactivating the second locking circuit, included in the first steering controller, to the second steering controller.
