An engine start system includes a starter (600) starting an engine, a starter drive relay (300) controlling the starter (600) and an engine ECU (100) connected to a starter switch (200) for controlling on/off of the starter drive relay (300) based on a predetermined start condition. The engine start system further includes a normally closed relay (400) connected to the starter switch (200), the engine ECU (100) and the starter (600) for establishing a de-energized state between the starter switch (200) and the starter (600) upon energization from the engine ECU (100) to an exciting coil and establishing an energized state between the starter switch (200) and the starter (600) upon de-energization of the exciting coil. The engine ECU (100) includes a circuit energizing the exciting coil of the normally closed relay (400) upon turn-on of the engine ECU (100).
An engine start control device comprising:
An engine start control method of an engine start control device including a motor (600) for starting an engine of a vehicle, a motor control relay (300) making a switch between supply and stop of electric power to said motor (600), a control circuit (100, 700) connected to an engine starter switch (200) and controlling opening/closing of said motor control relay (300) based on a predetermined start condition, and a normally closed relay (400) connected to said engine starter switch (200), said control circuit (100, 700) and said motor (600), establishing a de-energized state between said engine starter switch (200) and said motor (600) upon energization from said control circuit (100, 700) to an exciting coil and establishing an energized state between said starter switch (200) and said motor (600) upon de-energization of the exciting coil, and
