Abstract:
1. An engine control device for controlling a startup of an engine in a vehicle by directing an electric current from a power source to a starter motor and a coil for switching a connection state between an output shaft of the starter motor and the engine, the engine control device comprising: a delay unit configured to delay and cut-off a flow of the electric current from a first current system which directs the electric current to the coil to a second current system which directs the electric current to the starter motor; and a control unit configured to control a first switch to be energized by turning on the electric current from the power source to the first current system and to be cut-off by turning off the electric current from the power source to the first current system, and to control a second switch to be energized by turning on the electric current from the power source to the second current system and to be cut-off by turning off the electric current from the power source to the second current system, wherein the delay unit delays a flow of the electric current from the first current system to the second current system when a starting switch which is configure to be energized when a user turns on the electric current from the power source to the first current system and to be cut off when the user turns off the electric current from the power source to the first current system is turned on to cause the electric current to flow in the first current system, and wherein the delay unit cuts off the flow of the electric current from the first current system to the second current system when the first switch is turned on to cause the electric current to flow in the first current system.
