Abstract
An ignition coil control system includes: a plurality of ignition coils that respectively include a primary coil and a secondary coil; a spark plug that generates a spark discharge by a discharge current generated by the plurality of ignition coils and that includes a center electrode and a ground electrode; a sensing part measuring a current applied to the primary coil; and an ignition controller that adjusts a reference duty signal based on an amount of the current applied to the primary coil sensed by the sensing part to adjust discharge energy generated between the center electrode and the ground electrode through the secondary coil.
