Zusammenfassung:A steering control apparatus is provided which allows mitigation of an adverse effect of a technique for fixing a regulation member to a vehicle body on a phenomenon resulting from execution of steering operation control on steered wheels. An axial-force acquisition processing circuit M42 calculates a rack axial force AF based on currents iu, iv, and iw flowing through a steering operation motor. A correction processing circuit M40 corrects a target steered angle ¸p1* based on the rack axial force AF to obtain a target steered angle ¸p*. A steered angle control processing circuit M36 calculates a torque command value Trqt* as the amount of operation for adjusting a steered angle ¸p to the target steered angle ¸p* through feedback control. An operation signal generation processing circuit M38 controllably adjusts a torque of a steering operation motor to the torque command value Trqt*.
