摘要： 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.

摘要： A main power supply having a large capacity and a backup power supply having a small capacity are switchable by a power supply switching determination unit in a system. A motor control device drives a motor by the main power supply or the backup power supply. A drive control unit outputs a drive signal, calculated by feedback control of the current detection value with respect to the current command value, to an inverter circuit. When the power supply switching determination unit switches from the main power supply to the backup power supply, the drive control unit moves from a normal control using the main power supply to a backup control that restricts an electric power consumption and prevents the backup power supply from stopping.
