Abstract
An ignition control device for controlling an ignition coil device for an internal combustion engine, having an angle measuring device for measuring the current crank angle of the internal combustion engine and for outputting an equidistant angle pulse signal and an angle signal for indicating the respective beginning of a working cycle. The ignition control device includes a synchronization device for synchronizing the angular positions of the individual cylinders to the output signal of the angle measuring device, a rotational speed measuring device for measuring the rotational speed of the internal combustion engine at a measuring time point within the ignition cycle of an individual cylinder, and a calculating device for calculating a preestablished ignition angle corresponding to the measured rotational speed. A preestablished charging time corresponds to the measured battery voltage, and a beginning charging angle corresponds to the respective calculation angles in accordance with the synchronization. An ignition control value output device for outputting the beginning and the ending of the charging time.
