Starting system for vehicle

A starting system for a vehicle comprising:

• a power source switching unit for switching between a first voltage source and a second voltage source;
• a starting control unit for switching the power source switching unit in accordance with a state of the vehicle;
• an engine control unit for transmitting a starting signal to the starting control unit;
• and
• a magnet switch for controlling power from either the first voltage source or the second voltage source and routing it to a starter motor.

A method of controlling a starting control unit of a vehicle engine starting system, the method including the steps of:

• determining whether a key switch is connected to an ON terminal;
• determining whether an automatic starting signal is received from an engine control unit of the engine when the key switch is connected to an ON position;
• turning a magnet switch to an ON position when the automatic starting signal is received from the engine control unit to begin a passage of current to a starter motor;
• turning a second starter relay ON when the automatic starting signal is received from the engine control unit;
• determining whether an automatic starting signal is OFF after the second starter relay is turned ON;
• turning a second starter relay OFF when an automatic starting signal is OFF;
• and
• turning a magnet switch to an OFF position in order to stop a passage of current through the starter motor.
