Abstract

A vehicle system includes a fuel cell system, a battery, a drive device that operates with power, a load different from the drive device, a positional information acquisition unit, a traveling route setting unit, and a control device configured to control power to be supplied to the load from the fuel cell system and the battery based on positional information acquired by the positional information acquisition unit and a traveling route set by the traveling route setting unit.

First claim

What is claimed is:

1 . A vehicle system comprising:
a fuel cell system; a battery; a drive device that operates with power; a load different from the drive device; a positional information acquisition unit; a traveling route setting unit; and a control device configured to control power to be supplied to the load from the fuel cell system and the battery based on positional information acquired by the positional information acquisition unit and a traveling route set by the traveling route setting unit.

2 . The vehicle system according to claim 1 , wherein the traveling route setting unit sets one of an urban route for traveling an urban area and a non-urban route for traveling a non-urban area.

3 . The vehicle system according to claim 2 , further comprising:
a battery temperature information acquisition unit configured to acquire temperature information of the battery, wherein, when an urban route for traveling an urban area is set by the traveling route setting unit, and a temperature of the battery acquired by the battery temperature information acquisition unit is lower than a set predetermined temperature, power is supplied to the load from both of the fuel cell system and the battery.

4 . The vehicle system according to claim 2 , further comprising:
a battery temperature information acquisition unit configured to acquire temperature information of the battery, wherein, when an urban route for traveling an urban area is set by the traveling route setting unit, and a temperature of the battery acquired by the battery temperature information acquisition unit is equal to or higher than a set predetermined temperature, an operating status of the fuel cell system is changed according to a remaining capacity of the battery.

5 . The vehicle system according to claim 4 , wherein, when a remaining capacity of the battery is higher than a predetermined remaining capacity set based on positional information acquired by the positional information acquisition unit, the fuel cell system is stopped.

6 . The vehicle system according to claim 4 , wherein, when a remaining capacity of the battery is lower than a predetermined remaining capacity set based on positional information acquired by the positional information acquisition unit, an output of the fuel cell system is made to be higher than an output at which efficiency of the fuel cell system is maximized.

7 . The vehicle system according to claim 4 , wherein a plurality of fuel cell systems are included, and when a remaining capacity of the battery is lower than a predetermined remaining capacity set based on positional information acquired by the positional information acquisition unit, the number of the fuel cell systems to be operated is increased.

8 . The vehicle system according to claim 5 , wherein the predetermined remaining capacity is set based on at least one of positional information acquired by the positional information acquisition unit and a traveling route set by the traveling route setting unit.

9 . The vehicle system according to claim 2 , wherein, when a non-urban route for traveling a non-urban area is set by the traveling route setting unit, power is supplied to the load from the fuel cell system and the fuel cell system is controlled to have a predetermined amount of power generation.

10 . A control method of the vehicle system according to claim 1 , comprising:
controlling, by a computer, power supplied to the load from the fuel cell system and the battery based on positional information acquired by the positional information acquisition unit and a traveling route set by the traveling route setting unit.

11 . A control program of the vehicle system according to claim 1 causing a computer to execute
controlling power to be supplied to the load from the fuel cell system and the battery based on positional information acquired by the positional information acquisition unit and a traveling route set by the traveling route setting unit.
