  • Vehicle control apparatus, vehicle, and vehicle control method
    Patent number: 9567967
    Abstract: An auxiliary current amount that is used in an auxiliary that is mounted in a vehicle is calculated. A stop time ratio of the vehicle is calculated based on a running history of the vehicle, and an estimated stop time of the vehicle that is estimated based on the stop time ratio is calculated. An SOC threshold is set based on an estimated consumption current amount that is obtained from the estimated stop time and the auxiliary current amount. A generator that is mounted in the vehicle is operated such that a value of a storage state of the battery recovers to become larger than the SOC threshold when the value of the storage state of the battery is smaller than the SOC threshold.
