Abstract
A vehicular accessories drive apparatus includes a main engine, a subsidiary engine, and vehicular accessories that are driven by the main engine or the subsidiary engine. Furthermore, a fuel consumption predicting portion predicts an amount of fuel that is consumed in order for the main engine to drive the vehicular accessories during operation of the engine, and an amount of fuel that is consumed in order for the subsidiary engine to drive the vehicular accessories. An electromagnetic clutch carries out the switching between driving force sources so that the vehicular accessories are driven by the subsidiary engine if the predicted fuel consumption of the main engine is greater than the predicted fuel consumption of the subsidiary engine, and so that the vehicular accessories are driven by the main engine if the predicted fuel consumption of the main engine is less than or equal to the predicted fuel consumption of the subsidiary engine.
