摘要:
An ignition control device includes an ignition coil, a main ignition circuit unit for performing a main ignition operation, and an energy input circuit unit for performing an energy input operation. A main ignition signal generation circuit generates a main ignition signal such that a point in time when a waiting time has passed from a detection start time of a first signal of an ignition control signal at which a signal level of the ignition control signal changed from a first level to a second level for the first time, and the signal level of the ignition control signal is the second level, is a start of the main ignition signal, and a detection end time of a second signal of the ignition control signal at which the signal level of the ignition control signal shifts to the first level thereafter is an end of the main ignition signal.
