Abstract
An engine control apparatus is provided that controls an engine which is restarted using an AC motor. The engine control apparatus comprises an engine rotational direction determining section, a restart command determining section and an engine restart prohibiting section. The engine rotational direction determining section is configured to determine a rotational direction of the engine. The restart command determining section is configured to determine if a restart command occurred while a rotational speed of the engine is decreasing due to an idle stop command. The engine restart prohibiting section is configured to selectively prohibit the engine from being restarted by the AC motor in response to the restart command upon determining the engine is rotating backward.
