摘要：
In a vehicular steering control device, a steer-by-wire system, and a method for controlling a steer-by-wire system according to the present invention, if an abnormality of a rotation angle sensor of a turning motor is detected, open-loop control is performed on the turning motor based on a rotation angle of a motor shaft before the abnormality of the rotation angle sensor is detected and information concerning a reaction generation device that applies reaction torque to steering wheel. Consequently, it is possible to continue control of a turning angle even if the rotation angle sensor of the turning motor fails, while suppressing an increase in system cost.
