Abstract
A steering control apparatus is obtained which can achieve a sophisticated control function and redundancy of a motor output torque control unit with a simple construction. The apparatus includes a motorthat provides assist torque to a steering system, and a processing unitthat has an input processing sectionfor taking in detection signals of various kinds of sensors, and an inverterfor driving the motor, wherein a command is given to the inverterbased on the detection signals. The processing unithas a motor target output torque calculation section, a motor output torque control unit, a plurality of main-calculation sections, and a plurality of sub-calculation sections corresponding to the main-calculation sections, and determines abnormality of the motor output torque control unitbased on individual calculation results of the main-calculation sections and the sub-calculation sections.
