Abstract:
1. A rotary electric machine control apparatus for controlling a rotary electric machine, which has two winding sets formed of coils corresponding to plural phases, the rotary electric machine control apparatus comprising: two inverter units provided in correspondence to the two winding sets for converting electric power from a power source to the rotary electric machine by turning on and off plural switching elements, which include high-potential side switching elements provided at a high-potential side of the power source and low-potential side switching elements provided at a low-potential side, the high-potential side switching element and the low-potential side switching element forming a switching element pair corresponding to a phase of the winding in each of the winding set; a current detection device for detecting a phase current flowing in each of the two inverter units; and a control unit for controlling driving of the rotary electric machine by controlling on/off operations of the switching elements of the two inverter units, wherein the control unit includes an abnormality detection device for detecting, before starting of drive control for the rotary electric machine, a short-circuit abnormality between the two winding sets or the two inverter units based on a current detection value of the current detection device by turning on only at least one of the high-potential side switching elements of one of the two inverter units and at least one of the low-potential side switching elements of the other of the two inverter units.
