A controller includes a first absolute rotation angle calculation section, a second absolute rotation angle calculation section, and an abnormality detection section. The first absolute rotation angle calculation section calculates a first absolute rotation angle as a first estimate of an absolute rotation angle of a steering wheel based on the first and third rotation angles. The second absolute rotation angle calculation section calculates a second absolute rotation angle as a second estimate of the absolute rotation angle of the steering wheel based on the third and fourth rotation angles. The abnormality detection section detects an abnormality by comparison between the first absolute rotation angle and the second absolute rotation angle.

Abstract: In related art technique, an average neutral point voltage is detected via a low-pass filter. Time constant of the low-pass filter must be set to cover the entire output frequency band of an inverter and voltage fluctuation due to modulated signal must be separated from that due to a short circuit to ground. According to the present invention, whether abnormality such as a short circuit to ground or to supply occurs in output lines can be determined based on an actual neutral point voltage of a motor, which changes in a stepwise fashion in conformity to a PWM pulse pattern output by an inverter device, and a normal neutral point voltage which depends on a PWM pattern output by the inverter device. Highly reliable abnormality detection in accordance with the waveform of the neutral point voltage and stable abnormality detection not depending on the inverter output frequency are feasible.

The command current correcting circuit corrects the command current so that when the normal input is judged, torque in the same direction as input shaft rotation direction generated by the electric motor is greater than a case of reverse input judgment.
