ENGINE START CONTROLLER, ENGINE START CONTROL METHOD, AND RECORDING MEDIUM HAVING PROGRAM RECORDED THEREIN FOR PERFORMING THE METHOD

摘要

An engine start system comprises a starter (600) for starting an engine, a starter drive relay (300) for controlling the starter (600), and an engine ECU (100) connected to a starter switch (200) for on-off controlling the starter drive relay (300) on the basis of predetermined start conditions. The engine start system includes a normally closed relay (400) connected to the starter switch (200), engine ECU (100), and starter (600), and adapted to establish an electrically non-conductive state between the starter switch (200) and the starter (600) when an exciting coil is energized from the engine ECU (100) and to establish an electrically conducive state between the starter switch (200) and the starter (600) when the exciting coil is not energized. The engine ECU (100) includes a circuit adapted to energize the exciting coil for the normally closed relay (400) when the engine ECU (100) is turned on.
