VEHICLE CONTROL DEVICE, VEHICLE, AND VEHICLE CONTROL METHOD

摘要

To further improve fuel efficiency of vehicles. A vehicle control device that is mounted on a vehicle that has an engine, and a battery that can be charged by the amount of electric power that is generated by an alternator that is driven by power from the engine. The vehicle control device includes an idling stop control part 90, a battery SOC calculation part 120 that obtains the SOC of the battery, a target SOC estimation part 110 that sets a capacity for idling stop that is predicted to be used in a stop and start period between stop and restart of the engine by the idling stop control within the usable SOC range of the battery while the vehicle is running; and a remaining capacity control part 130 that controls the amount of electric power that is generated by the alternator to prevent the remaining capacity in the usable SOC range from falling below the capacity for idling stop while the vehicle is running that corresponds to the SOC.
