  • Patent number: 11207968
    Abstract: In a constant-speed traveling mode or a follow-up traveling mode, reduction of fuel consumption and improvement of drivability are both achieved. An ECU 110 has an ISG connected to an engine and a battery connected to the ISG. The ECU 110 has an ISG control unit 606 that performs control for supplying power to the ISG from the battery to rotationally drive the ISG, or to drive the ISG to generate power for charging the battery. In one cycle of a traveling mode until completion of deceleration traveling after acceleration traveling is started so as to achieve a target vehicle speed, the ISG control unit 606 drives the ISG such that a remaining charge amount of the battery falls within a set range at completion of the deceleration traveling, and a traveling acceleration/deceleration falls within a predetermined requested acceleration/deceleration.
