摘要： The present invention is to make it possible to effectively recover regenerative energy and improve a fuel efficiency. Thus, there is provided an HCM 50 of 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 HCM 50 is configured to include: a high efficiency range information storage unit 53 that 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 unit 51 that 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 unit 52 that 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.

摘要： There is provided a control device for vehicles which can improve quietness and fuel economy, while maintaining high responsiveness to acceleration of a vehicle. Therefore, the control device 100 for vehicles includes a gear ratio control unit 10 that controls a gear ratio of a vehicle V, and a determination unit 20 that determines whether or not there is an acceleration limit of the vehicle V. The gear ratio control unit 10 is configured to limit an increase in gear ratio Rt, when the determination unit 20 determines that there is an acceleration limit.

摘要： 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.
