Abstract
An increment of a fuel consumption rate caused by power generation is determined from a difference in fuel consumption rate between a case of performing power generation of an alternator and a case of stopping the power generation. The increment of the fuel consumption rate is divided by a power generation amount of the alternator to determine an increment of a fuel consumption per unit power generation amount. A use-frequency of the electric consumption is determined and also a possible power generation amount and average consumption power are calculated. A target electric consumption is set based upon the use-frequency, the possible power generation amount and the average consumption power so that the charge and discharge balance of the battery becomes zero. The present electric consumption is compared with the target electric consumption to determine whether or not to perform the power generation of the alternator.
