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.

Hybrid vehicle control apparatus and hybrid vehicle

Provided is a transmission control device which can improve drivability in an acceleration section even while taking a reduction of fuel consumption in a deceleration section into consideration. The transmission control device (transmission controller) which controls a transmission in a running control of a vehicle includes a shift timing calculation unit which determines an acceleration position at which the vehicle accelerates on the basis of a target speed pattern generated from external information, a target gear ratio calculation unit which determines a required gear ratio which is required at the acceleration position, and a gear ratio overwriting command unit which outputs a command of overwriting the gear ratio such that the gear ratio at the acceleration position approaches the required gear ratio. In the control of the transmission of the transmission controller, the gear ratio is set to the required gear ratio (target gear ratio) at a predetermined point after the vehicle exits the deceleration section and reaches the acceleration position.
