Abstract:
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 calculates a rack axial force based on currents iu, iv, and iw flowing through a steering operation motor. A correction processing circuit corrects a target steered angle based on the rack axial force to obtain a target steered angle. A steered angle control processing circuit calculates a torque command value as the amount of operation for adjusting a steered angle to the target steered angle through feedback control. An operation signal generation processing circuit controllably adjusts a torque of a steering operation motor to the torque command value.
