Abstract
In a motor control device for a steer-by-wire steering device, the motor control device having a redundant system consisting of two systems, a first turning current command value is calculated in a first system, and a second turning current command value is calculated in a second system. A third processor outputs the first turning current command value when the two current command values are not divergent and outputs the second turning current command value when the two current command values are divergent. When a determination of a rapid steering operation is made, the third processor outputs the first turning current command value regardless of whether or not the two current command values are divergent.
