Electrical source control apparatus

An electrical source control apparatus for controlling a vehicle which travels by using an electrical source system including both of first and second electrical sources,

• the first electrical source performing an input/output of a first electrical power,
• the second electrical source performing an input/output of a second electrical power, a capacity of the second electrical source being smaller than that of the first electrical source and an output of the second electrical source being larger than that of the first electrical source,
• the electrical source control apparatus comprising a controller,
• the controller being programmed to:
• select a first driving mode which prioritizes a fuel efficiency over a driving performance and a second driving mode which prioritizes the driving performance over the fuel efficiency on the basis of a characteristic which is required for the vehicle from a plurality of driving modes, each driving mode being associated with a ratio of the first electrical power with respect to a required electrical power which is required for the electrical source system, the ratios in the plurality of driving modes being different from each other;
• and
• control the first and second electrical sources such that the input/output of the first and second electrical powers are performed in accordance with the ratio of the selected first or second driving mode.
