Abstract
A battery supplies electric power to electric equipments of the vehicle. An alternator generates the electric power and charges the battery when an engine of the vehicle is operated. An economical running control section is operable to perform an economical running in which the engine is automatically stopped when the vehicle is in a predetermined engine stopping condition and the engine is automatically restarted when the vehicle is in a predetermined engine restarting condition. A calculate section is operable to calculate an available current value which is available to supply to the electric equipments from the battery. A feed limiting section is operable to limit to supply the electric power to the electric equipments from the battery. The economical running control section controls the economical running based on a total value of necessary current values which are necessary for the respective electric equipments and the available current value. The feed limiting section limits to supply the electric power to the electric equipments from the battery based on the total value of the necessary current values and the sum of the available current value and a generated current value of the alternator.
