Patent ID: 11697359

Abstract:
A distance-to-empty presentation apparatus of a fuel cell vehicle includes: a traveling speed acquisition unit configured to acquire a traveling speed of the fuel cell vehicle; a traveling distance acquisition unit configured to acquire a traveling distance of the fuel cell vehicle in a fuel filling period, the fuel filling period is a period from the time when the fuel is filled in the fuel cell vehicle previously to the time when the fuel is filled in the fuel cell vehicle this time; a fuel residual amount acquisition unit configured to acquire a fuel residual amount of the fuel cell vehicle; a fuel consumption amount acquisition unit configured to acquire a fuel consumption amount of the fuel cell vehicle; a fuel efficiency calculation unit configured to calculate fuel filling period fuel efficiency by using the traveling distance in the fuel filling period and a traveling period fuel consumption amount that is the fuel consumption amount during traveling preparation and during traveling in the fuel filling period, wherein the fuel filling period fuel efficiency is fuel efficiency in the fuel filling period; a distance-to-empty calculation unit configured to calculate a distance to empty of the fuel cell vehicle by using the fuel filling period fuel efficiency and the fuel residual amount; and a presentation device configured to present the distance to empty.
