Abstract:
1. An ignition control device for controlling a multi-spark operation associated with an internal combustion engine, comprising: an ignition coil including a primary coil and a secondary coil; a first electric energy generator for generating a first electric energy; a second electric energy generator for generating a second electric energy, a voltage of the second electric energy being larger than a voltage of the first electric energy; a switching element capable of controlling the supplying of the first electric energy and the second electric energy to the primary coil by switching on and off, the switching causing a secondary current of the secondary coil; an ignition timing signal generator for generating an ignition timing signal having a pulse waveform based on a driving state of the internal combustion engine; a multi-spark period setting element for setting a multi-spark period of the multi-spark operation based on a width of the ignition timing signal; and an ignition control element for setting an amount of electric power supplied to the first electric energy generator and the second electric energy generator based on the multi-spark period set by the multi-spark period setting element, and for controlling the switching element.
