A vehicle steering device and control method for use in steer-by-wire steering systems. A steering instrument (1) is operable to receive input from a driver and a turning device (14) is operable to turn at least one wheel (15). A selectively engageable backup clutch (7) is positioned between the steering instrument (1) and the turning device (14). Engagement of the backup clutch (7) results in a mechanical connection between the steering instrument and the turning device for assisting control of the at least one wheel, and release of the backup clutch (7) results in a separation of the steering instrument and the turning device for steer-by-wire control of the at least one wheel. A controller is operable to switch from the steer-by-wire control to the assisting control when the backup clutch (7) engages during operation of the steer-by-wire control.
