An engine start system includes a starter starting an engine, a starter drive relay controlling the starter and an engine ECU connected to a starter switch for controlling on/off of the starter drive relay based on a predetermined start condition. The engine start system further includes a normally closed relay connected to the starter switch, the engine ECU and the starter for establishing a de-energized state between the starter switch and the starter upon energization from the engine ECU to an exciting coil and establishing an energized state between the starter switch and the starter upon de-energization of the exciting coil. The engine ECU includes a circuit energizing the exciting coil of the normally closed relay upon turn-on of the engine ECU.

1. An engine start control device comprising:a motor for starting an engine of a vehicle; a motor control relay making a switch between supply and stop of electric power to said motor; and a control circuit connected to an engine starter switch and controlling opening/closing of said motor control relay based on a predetermined start condition, wherein said start control device includes a normally closed relay connected to said engine starter switch, said control circuit and said motor, establishing a de-energized state between said engine starter switch and said motor upon energization from said control circuit to an exciting coil and establishing an energized state between said starter switch and said motor upon de-energization of the exciting coil, and said control circuit includes control means for exercising control, based on a predetermined condition, to energize the exciting coil of said normally closed relay. 2. The engine start control device according to claim 1, whereinsaid control circuit enters an inoperative state when a voltage supplied from a power source installed in the vehicle drops below a predetermined voltage, and accordingly energization from said control circuit to said exciting coil is stopped. 3. The engine start control device according to claim 1, whereinsaid control circuit includes means for exercising control to energize the exciting coil of said normally closed relay upon satisfaction of a condition that supply of electric power from a power source installed in the vehicle to said control circuit is started. 4. The engine start control device according to claim 1, whereina switching circuit of said engine starter switch is closed so long as force is applied to the switch. 5. The engine start control device according to claim 1, whereinsaid normally closed relay is incorporated in said control circuit. 6. An engine start control method of an engine start control device including a motor for starting an engine of a vehicle, a motor control relay making a switch between supply and stop of electric power to said motor, a control circuit connected to an engine starter switch and controlling opening/closing of said motor control relay based on a predetermined start condition, and a normally closed relay connected to said engine starter switch, said control circuit and said motor, establishing a de-energized state between said engine starter switch and said motor upon energization from said control circuit to an exciting coil and establishing an energized state between said starter switch and said motor upon de-energization of the exciting coil, andsaid start control method comprising the step of exercising control, based on a predetermined condition, to energize the exciting coil of said normally closed relay. 7. The engine start control method according to claim 6, whereinsaid control circuit enters an inoperative state when a voltage supplied from a power source installed in the vehicle drops below a predetermined voltage, and accordingly energization from said control circuit to said exciting coil is stopped. 8. The engine start control method according to claim 6, whereinsaid step of exercising control to energize the exciting coil includes the step of exercising control to energize the exciting coil of said normally-closed relay upon satisfaction of a condition that supply of electric power from a power source installed in the vehicle to said control circuit is started. 9. The engine start control method according to claim 6, whereina switching circuit of said engine starter switch is closed so long as force is applied to the switch. 10. A recording medium having a program recorded thereon for allowing a computer to implement the start control method recited in claim 6.11. The engine start control device according to claim 2, whereinsaid control circuit includes means for exercising control to energize the exciting coil of said normally closed relay upon satisfaction of a condition that supply of electric power from a power source installed in the vehicle to said control circuit is started. 12. The engine start control device according to claim 2, whereina switching circuit of said engine starter switch is closed so long as force is applied to the switch. 13. The engine start control device according to claim 2, whereinsaid normally closed relay is incorporated in said control circuit. 14. The engine start control method according to claim 7, whereinsaid step of exercising control to energize the exciting coil includes the step of exercising control to energize the exciting coil of said normally-closed relay upon satisfaction of a condition that supply of electric power from a power source installed in the vehicle to said control circuit is started. 15. The engine start control method according to claim 7, whereina switching circuit of said engine starter switch is closed so long as force is applied to the switch. 16. A recording medium having a program recorded thereon for allowing a computer to implement the start control method recited in claim 7.
