Abstract:
A control unit of a rotary electric machine control apparatus includes a rotation position calculation section, which calculates a sensor angle by correcting a detection signal of a rotation position sensor based on correction value information specific to each sensor, and a correction value abnormality check section, which checks whether the correction value information is normal. When the correction value information is abnormal, the rotation angle calculation section corrects the detection signal of the rotation position sensor by using default value information in place of the correction value information. Each default value is limited to be different from the correction value within a predetermined range. A current command value calculation section sets a d-axis current command value to zero and fixes a current command phase to 90[°]. The current command phase is changed to be most remote from 0[°] and 180[°] thereby ensuring a tolerable range.
