Abstract:
An ignition device for an internal combustion engine, comprising:an output for electrical activation of an ignition element for a combustion area of the internal combustion engine, an electrical energy storage device for storing the electrical energy required to activate the ignition element, a control input to record a control signal controlling the charging process for the energy storage device and/or the ignition process from a controller, wherein the control input enables bi-directional data transmission with the controller, in order to give the controller feedback about the charging process for the energy storage device and/or the ignition process for the ignition element, while the control input is connected to a controllable current source in order to input a current signal at the control input to feed back to the controller, wherein the energy storage device is connected to a current metering unit, which records the charging current of the energy storage device, and a controllable sink connected to the control input, in order to input a current signal at the control input to feed back to the controller, whereby the current metering unit is connected to the controllable current sink or to the controllable current source, and the energy storage device is connected to a voltage metering unit, which monitors the ignition voltage, whereby the output side of the voltage metering unit is connected to the controllable current source or the controllable current sink, in order to input the current signal at the control input based on the ignition voltage.
