A vehicular accessories drive apparatus (1) includes a main engine (5), a subsidiary engine (6), and vehicular accessories (8a) that are driven by the main engine (5) or the subsidiary engine (6). Furthermore, a fuel consumption predicting portion (40b) predicts an amount of fuel that is consumed in order for the main engine (5) to drive the vehicular accessories (8a) during operation of the main engine (5), and an amount of fuel that is consumed in order for the subsidiary engine (6) to drive the vehicular accessories (8a). An electromagnetic clutch (30) carries out the switching between driving force sources so that the vehicular accessories (8a) are driven by the subsidiary engine if the predicted fuel consumption of the main engine (5) is greater than the predicted fuel consumption of the subsidiary engine, and so that the vehicular accessories (8a) are driven by the main engine (5) if the predicted fuel consumption of the main engine (5) is less than or equal to the predicted fuel consumption of the subsidiary engine. <IMAGE> |
