Abstract
A steering control apparatus is provided which suppresses possible vibration of a steering system resulting from differential steering processing when a steering angle or a steered angle has a large value. A differential steering processing circuit calculates a differential steering correction amount based on a difference value of a target steering angle, and increases or reduces the target steering angle using the calculated amount to obtain a target steered angle. A limiting reaction force setting processing circuit increases a limiting reaction force when a maximum value of the target steering angle and the target steered angle is equal to or larger than a common threshold. When the maximum value approaches the common threshold, an angle-sensitive gain setting processing circuit reduces an angle-sensitive gain so as to correct and reduce the differential steering correction amount.
