Abstract

An energy consumption predicting device includes: an acquisition unit acquiring a parameter correlated with at least one of a vehicle speed when a vehicle traveled on a route from a first point to a second point on which a vehicle traveling using only a power source consuming an energy source supplied from outside of the vehicle and stored therein is able to travel, a different vehicle speed when a different vehicle traveled on the route, an output of the power source when the vehicle traveled on the route, and an output of a different power source when the different vehicle traveling using only the same type of different power source as the power source traveled on the route; and a calculation unit calculating a predicted consumption of the energy source which is predicted when the vehicle travels on the route from the first point to the second point.

4. The energy consumption predicting device according to claim 1, wherein the acquisition unit acquires the parameter from a server which is disposed outside the vehicle by radio communication.

5. The energy consumption predicting device according to claim 1, wherein the calculation unit calculates the predicted consumption based on a gradient of the route and the parameter correlated with at least one of the vehicle speed and the different vehicle speed.

6. The energy consumption predicting device according to claim 1, wherein the calculation unit calculates the predicted consumption based on the output of the power source which is consumed by an air-conditioning device of the vehicle or consumption of the energy source.

7. The energy consumption predicting device according to claim 1, wherein the power source is a fuel cell that consumes fuel gas as the energy source stored in a fuel tank.

8. An energy consumption predicting method comprising:

acquiring a parameter correlated with at least one of a vehicle speed when a vehicle traveled on a route from a first point to a second point on which the vehicle traveling using only a power source consuming an energy source supplied from outside of the vehicle and stored therein is able to travel, a different vehicle speed when a different vehicle traveled on the route, an output of the power source when the vehicle traveled on the route, and an output of a different power source when the different vehicle traveling using only the same type of different power source as the power source traveled on the route as an acquisition step; and
