Engine starting apparatus
First Claim
1. An engine starting apparatus comprising:
- a microcomputer that operates on a control-use voltage generated by stepping down a battery voltage of a vehicle battery, and is configured to output a drive signal individually to first and second relays of a starter of said vehicle engine to drive said first and second relays to thereby cause said starter to operate when predetermined engine start conditions are satisfied, and to be reset when said control-use voltage decreases below a predetermined reset voltage; and
an inter-relay switch configured to make electrical connection between said first and second relays when said first relay is applied with said battery voltage, said second relay being applied with said battery voltage when said electrical connection is made;
said first relay being configured to be applied with said battery voltage when a manual start switch is operated.

Abstract
The engine starting apparatus operates on battery voltage when the battery voltage is higher than a predetermined voltage to control starting of an engine of a vehicle. The engine starting apparatus includes a relay control section configured to output a drive signal individually to first and second relays of a starter of the vehicle engine to drive the first and second relays when predetermined engine start conditions are satisfied, the starter being configured to operate when the first and second relays are driven, and an inter-relay switch configured to make electrical connection between the first and second relays when the first relay is applied with the battery voltage, the second relay being applied with the battery voltage when the electrical connection is made. The first relay is configured to be applied with the battery voltage when a manual start switch is operated.
