A device for predicting energy consumption includes an obtaining unit (), an air resistance calculating unit (), and an energy consumption predicting unit (). The obtaining unit () is configured to obtain road information including traveling speed information set for each route. The air resistance calculating unit () is configured to calculate air resistance as a calculated air resistance value by an air resistance calculation formula on the basis of the traveling speed information of the scheduled traveling route and to correct the calculated air resistance value so that the air resistance is higher according as the traveling speed along the scheduled traveling route is lower. The air resistance is caused when a vehicle travels along a scheduled traveling route. The energy consumption predicting unit () is configured to predict an energy consumption of the scheduled traveling route on the basis of the corrected air resistance value.

Device for predicting energy consumption and method for predicting energy consumption

A vehicle includes a fuel tank, a fuel amount detecting device and a control device. The fuel amount detecting device is configured to detect an amount of fuel inside the fuel tank. The control device is configured to calculate an estimated refueling amount that diminishes fuel inside the fuel tank from degrading based on a usage history of the vehicle. The control device is further configured such that the control device stops refueling based on an amount of fuel detected by the fuel amount detecting device and the estimated refueling amount.
