Claim Text:
1. A steering control system for a vehicle, comprising: an electric motor configured to apply assist force to a turning operation of a steering wheel; a torque sensor configured to detect a torque that is generated in a steering system including the steering wheel and that varies with the turning operation of the steering wheel; an angular velocity sensor configured to detect an angular velocity that is generated in the steering system including the steering wheel and that varies with the turning operation of the steering wheel; and a control unit configured to compute an assist control amount for the turning operation of the steering wheel by using the torque and the angular velocity, and configured to, when there occurs an abnormality in an operation of the torque sensor to detect the torque, increase a first control amount that is computed by using the angular velocity detected by the angular velocity sensor among control amounts that constitute the assist control amount as compared to that when the operation of the torque sensor to detect the torque is normal and execute drive control over the electric motor on the basis of the assist control amount.
