Rotary electric machine control apparatus

A rotary electric machine control apparatus for controlling driving of a rotary electric machine, which is a drive power source of a vehicle, the rotary electric machine control apparatus comprising:

• a temperature calculation part for calculating a system temperature of a rotary electric machine driving system in response to a temperature of an inverter part or a temperature of a booster part sensed by a temperature sensor;
• and
• a torque limitation part for limiting a torque of the rotary electric machine, when the system temperature increases to be higher than a limitation starting temperature,
• wherein the torque limitation part continues a torque limitation performed at a peak temperature of the system temperature until a limitation continuation period elapses, the peak temperature indicating a change of the system temperature from increasing to decreasing as a result of limiting the torque of the rotary electric machine,
• wherein the rotary electric machine driving system includes the rotary electric machine and a driving circuit part, and
• wherein the driving circuit part includes the inverter part for switching over current supply to the rotary electric machine and/or the booster part for boosting DC power of an output voltage.
