Abstract
An engine controller controls an engine, which drives a generator, an auxiliary device, and a vehicle. The generator generates electricity, and supplying the electricity to a battery and a plurality of current consumers. A generator controller controls the generator. An auxiliary device controller controls the auxiliary device. An electric power generation calculation unit calculates one of a requested power generation of the generator and a present power generation of the generator. An engine speed changing unit evaluates tendency of power generation on the basis of the one of the requested power generation and the present power generation. The engine speed changing unit requests increase or decreases in the engine speed when the engine speed changing unit determines the power generation to be inclined toward shortage or excess.
