Abstract:
An ignition control device for controlling an ignition coil device for an internal combustion engine having at least one cylinder and at least one driver stage, comprising:an engine speed detection device for detecting an engine speed of the internal combustion engine; an angle detection device for detecting an instantaneous crankshaft angle of the internal combustion engine; a first determination device for determining an ignition angle, a charging time, and a start-of-charging angle corresponding to the detected engine speed; a second determination device for determining an instantaneous temperature of the at least one driver stage; a calculation device for calculating a future temperature of the at least one driver stage; and an output device that is one of operable in a charging time output mode if one of the instantaneous temperature and the future temperature of the at least one driver stage exceeds a temperature threshold and operable in an ignition angle output mode if one of the instantaneous temperature and the future temperature of the at least one driver stage does not exceed the temperature threshold, wherein: the output device operating in the charging time output mode outputs the start-of-charging angle and the charging time, the output device operating in the ignition angle output mode outputs the start-of-charging angle and the ignition angle, a time elapsed from a given reference is determined by a comparison to a timer, and an angle from a given reference point is determined by a comparison to a signal of the angle detection device.
