A BOOSTER CONTROL APPARATUS AND AN IDLING-STOP SYSTEM USING THE SAME

A booster control apparatus (22) for controlling a booster (20) provided between a battery (10) and a load (30) in an idling-stop vehicle in which a boosting operation of the booster is initiated in connection with a restart of an engine after an idling-stop, is disclosed. When the boosting operation of the booster is initiated in connection with the restart of the engine after the idling-stop, the booster control apparatus (22) sets the target voltage in such a manner that the target voltage gradually increases from a second target voltage, which corresponds to the battery voltage at the beginning of the boosting operation of the booster, to a first target voltage which corresponds to the battery voltage at the time of a stop of the engine.
