摘要：
In a steering control system, an ECU calculates a basic transfer ratio in accordance with a steering angle detected by a steering angle sensor or a corrected transfer ratio by correcting the calculated basic transfer ratio in accordance with the position of a rack. The corrected transfer ratio decreases when the rack moves from a predetermined first position close to one end of a movable range, to the one end or from a predetermined second position close to the other end of the movable range, to the other end. The ECU determines either the basic transfer ratio or the corrected transfer ratio as the transfer ratio in accordance with the position of the rack. The ECU controls an actuator for a variable gear ratio system in accordance with the transfer ratio.
