Control method for ISG of vehicle provided with manual transmission and vehicle of which the control method is applied

A vehicle implementing an idle stop-and-go (ISG) function and provided with a manual transmission, the vehicle comprising:

• a vehicle operation state detector including:
• a shift sensor configured to detect a shift stage of the manual transmission and output a corresponding signal,
• a clutch pedal sensor configured to output a top signal or a bottom signal based on an operation of a clutch pedal,
• a brake pedal sensor configured to detect an operation of a brake pedal and output a corresponding signal, and
• a vehicle speed sensor configured to measure a vehicle speed and output a corresponding signal;
• an injector configured to inject fuel into an engine;
• an operation motor connected to the engine and configured to selectively start the engine;
• a controller configured to control the injector and the operation motor based on the corresponding signals from the vehicle operation state detector;
• and
• a memory configured to communicate with the controller and configured to record the vehicle speed,
• wherein:
• based on the corresponding signals from the vehicle operation state detector, the controller is configured to:
• determine that an ISG function activation condition is satisfied when the shift stage of the manual transmission is a neutral stage, an operation signal of the clutch pedal sensor is not generated, and a current vehicle speed is lower than a predetermined first reference vehicle speed, and the vehicle speed recorded in the memory is higher than a predetermined second reference vehicle speed, and
• when the ISG function activation condition is satisfied, the controller is configured to control the injector to stop fuel injection into the engine.
