Abstract: An ignition coil control method may include receiving first pulse signal and second pulse signal following the first pulse signal by a delay time transmitted from an engine control unit; charging the first ignition coil when the first pulse signal is on; charging the second ignition coil when a predetermined time period elapses from a time at which the first pulse signal is on; discharging the first ignition coil when the first pulse signal is off; discharging the second ignition coil when a maintaining time of the first pulse signal from a time at which the second ignition coil is charged; when the second pulse signal is on, charging the first ignition coil for a dwell time and then discharging the first ignition coil; and charging the second ignition coil for the dwell time and then discharging the second ignition coil when a predetermined time period elapses from a time at which the second ignition coil is discharged.
