Abstract
Provided is an ignition control device capable of suppressing wear of an ignition plug due to occurrence of a re-strike without adding a component. An ECU 123 used as an ignition control device includes: an ignition signal calculation unit 203 that calculates a start timing and an end timing of re-energization with a primary current in one ignition process, compares the end timing of the re-energization with the timing at which the frequency of occurrence of a re-strike decreases, and determines whether to perform the re-energization; and an ignition signal generation unit 204 that generates an ignition signal for generating at least one or more spark discharges in the ignition process, outputs the ignition signal to the ignition coil, then generates the ignition signal when the ignition signal calculation unit determines to perform the re-energization, outputs the ignition signal to the ignition coil at the start timing of the re-energization, and does not generate the ignition signal when the ignition signal calculation unit determines not to perform the re-energization.
