VEHICLE CONTROL DEVICE, VEHICLE, AND VEHICLE CONTROL METHOD

There is a need to further improve the fuel consumption of a vehicle. There is provided a vehicle control device mounted on a vehicle having: an engine; a battery that is chargeable with an amount of electric power generated by a generator which is driven with power of the engine; and auxiliary machinery that are operated with electric power of the battery. The vehicle control device comprises an idle reduction controller, an SOC detector, a current value obtaining section, a current correcting section, an idle reduction capacity setting section and a remaining capacity controller. The current correcting section comprises: a smoothing process section that makes the current value obtained by the current value obtaining section subject to a smoothing process (S160); a specific auxiliary machine operation detecting section that determines whether a specific auxiliary machine, which is included in the auxiliary machinery and is likely to have a temporary abrupt change of the current value, is in an operating state (step S140); and a current change suppressing section that suppresses an effect of a latest current value obtained by the current value obtaining section, in the smoothing process, when the specific auxiliary machine is determined to be in the operating state (S180).
