Steering apparatus for vehicle and control method therefor

A control method for a vehicle for steering based on a steering-by-wire (SBW) system, the control method for a vehicle comprising: calculating a maximum limit steering value of a steering wheel when an abnormality occurs in the SBW system; calculating a correction coefficient for the maximum limit steering value on the basis of a speed of the vehicle and a road surface condition; generating endpoint reaction force feeling for the steering wheel; determining whether a required steering value input to the steering wheel exceeds the maximum limit steering value; and transmitting a warning sound and applying a reaction force to the steering wheel when a determination is made that the required steering value exceeds the maximum limit steering value.
