Idle Speed Stopped Vehicle

The invention provides an idle speed stopped vehicle which prevents idle speed stopping on condition that an actual charging state is lower than an idle speed stopping permitting threshold. An engine controller (10) determines whether the charging state of a battery (7) exceeds the idle speed stopping permitting threshold. On condition that exceeding of the charging state of the battery over the idle speed stopping permitting threshold is determined, the battery (7) is charged through a maximal error amount of the charging state that exceeds the idle speed stopping permitting threshold relative to the actual charging state, and then an engine (2) is stopped automatically. On condition that automatic stopping of the engine (2) is permitted, the engine (2) is stopped automatically.
