System and method for controlling ignition coil

A method for controlling an ignition coil, the method comprising:

• determining an operation region of an engine;
• performing a multi-stage ignition or a single-stage ignition based on the determined operation region;
• while performing the multi-stage ignition, determining whether a misfire occurs in the engine;
• and
• in response to a determination that the misfire occurs in the engine while performing the multi-stage ignition, temporarily increasing a number of ignitions or a dwell time.

A vehicle comprising;

• a vehicle body;
• a battery mounted in the vehicle body;
• an engine mounted in the vehicle body, the engine comprising a plurality of cylinders;
• an ignition coil comprising a first ignition coil comprising a first primary coil and a first secondary coil and a second ignition coil comprising a second primary coil and a second secondary coil, wherein a first end of the first primary coil and a first end of the second primary coil are electrically connected to the battery;
• a spark plug mounted in a cylinder of the plurality of cylinders, the spark plug comprising a pair of electrodes configured to generate a spark discharge by a discharge current generated by the first ignition coil and the second ignition coil;
• a detector configured to detect whether a misfire of the engine occurs;
• and
• a controller configured to:
• determine an operation region of the engine;
• selectively perform a multi-stage ignition through the first ignition coil and the second ignition coil or a single-stage ignition through the first ignition coil or the second ignition coil based on the determined operation region of the engine;
• and
• while performing the multi-stage ignition, and in response to a determination that the misfire of the engine occurs, adjust a number of ignitions or a dwell time.
