Abstract
A current is supplied to a driving relay that drives a bypass relay when restarting an engine after idle reduction, and the current supply to the driving relay is interrupted when the engine is started for the first time based on operation of a driver.
Claims2
An engine starting device of an idle reduction vehicle that automatically stops an engine when a predetermined engine stopping condition is satisfied and that restarts the engine by operating a starter motor when a predetermined engine restarting condition is satisfied, the engine starting device comprising:
- a resistor that is arranged in series between the starter motor and a battery;
- a bypass relay that is arranged in parallel to the resistor and that has a structure of a normally close contact maintaining a relay contact in an open state by energization;
- a current supply path to which a current is supplied from the battery when an ignition switch is on, and to which the current supply from the battery is interrupted when the engine is started initially based on operation of a driver;
- and
- a control unit configured to control whether or not a supplied current from the current supply path is supplied to the bypass relay for the energization.
