Reachable range calculation device, method, and program

摘要

A reachable range calculation device for calculating a reachable range of a vehicle traveling with accumulated energy, wherein information on a required energy amount consumed when the vehicle moves is obtained in advance for each area obtained by dividing the map into a plurality of areas. A storage unit for storing and an accumulating unit for accumulating the required energy amount every time the vehicle moves between the areas based on the required energy amount stored in the storage unit for the movement of the vehicle from the designated start point position to the surroundings And a range determining unit that determines a reachable range that is a range of a region that the vehicle can reach with the specified energy amount, based on the given specified energy amount and the integrated required energy amount that the integrating unit has integrated the consumed energy amount; ,have.
