Control apparatus and control method for hybrid vehicle

A controlling apparatus of a hybrid vehicle comprising a motor generator that is mechanically connected to an internal combustion engine and that can generate power in response to rotation of the internal combustion engine and provide torque to the internal combustion engine, the controlling apparatus comprising:

• a rotation information acquiring unit that acquires rotation information of the motor generator with a higher resolution than rotation information of the internal combustion engine;
• and
• a power generation determining unit that makes a determination regarding the power generation by the motor generator based on the rotation information of the motor generator, wherein the power generation determining unit permits idle power generation by the motor generator when starting of the internal combustion engine is completed and a starting completion reference time has passed,
• wherein the power generation determining unit accepts or does not permit the idle power generation by the motor generator, based on a result of comparing a rotational speed of the motor generator and a power generation possible reference rotational speed.
