Abstract
The present invention is to make it possible to effectively recover regenerative energy and improve a fuel efficiency. Thus, there is provided an HCMof a hybrid vehicle, in which the hybrid vehicle includes: an engine; a drive wheel to which a driving force of the engine is transmittable; a motor to which the driving force from the engine is transmittable and which is capable of transmitting a driving force to the drive wheel; and a battery which supplies power for driving the motor and stores power generated by the motor. The HCMis configured to include: a high efficiency range information storage unitthat stores information specifying a high efficiency range in which an engine efficiency of the engine is high in an engine characteristic of the engine; a power generation amount measurement unitthat measures a low efficiency range power generation amount, which is an amount of power generated by the motor and stored in the battery when the engine operates in a low efficiency range being out of the high efficiency range; and an integrated control unitthat controls power of the low efficiency range power generation amount to be supplied from the battery to the motor when it is necessary to supply power for driving the motor.
