Abstract

Provided is a steering control apparatus configured to suppress the occurrence of abnormalities in components in respective systems at the same timing. A first assist torque calculation circuit calculates a first command value and a second command value based on a steering torque. A first current feedback control circuit calculates a control signal by using the first command value. A second current feedback control circuit calculates a control signal by using the second command value. When the steering torque is equal to or smaller than a steering torque threshold, the first assist torque calculation circuit executes calculation so that the first command value is larger than the second command value. After the steering torque exceeds the steering torque threshold, the first assist torque calculation circuit executes calculation so that the first command value is equal to the second command value.
