A control apparatus for driving a three-phase rotary electric machine that generates torque including magnet torque and reluctance torque is provided. AC current supplied to two winding groups of the rotary electric machine have the same amplitude and the mutually different phases defined as 30±60×n[deg]. The control unit calculates d-axis current and q-axis current of 6 (2k+1)th order component superposed on a fundamental wave component on dq coordinate, to reduce a peak of the first order component in the phase current, thereby controlling the three-phase rotary electric machine. The control unit calculates current such that an amplitude of the q-axis current of the 6 (2k+1)th order component is larger than an amplitude of the d-axis current of the 6 (2k+1)th order component.

Electronic control units (ECUs) provided with circuits for backing up other ECUs lack versatility and increase costs. In the present invention, motor control ECUs respectively control motors via signal wires that perform motor control. In addition, a dedicated substitute ECU is connected to each motor via signal wires that perform motor control. A substitute control circuit part of the dedicated substitute ECU runs to a network, is continuously receiving malfunction information and stability information via a signal wire, and detects the malfunction of the motor control ECU from said information. Then the dedicated substitute ECU substitutes for the motor control ECU and performs a backup operation to continue control of the motor via the signal wire.
