Various embodiments of the teachings herein include methods and/or systems for operating a power system having a central control unit and two power system components. The method may include: determining a self-estimated value for each power system component based on a respective state value; providing the central control unit with a present maximum amount of power for each of the components; receiving a request for a demanded electrical power; ascertaining a distribution variable relating to the demanded power for each component based on the self-estimated values and the maximum amount of power output; and distributing a demanded electrical power to the power system components. The power system components comprise an energy generator unit, an energy consumer unit, or an energy storage unit.

Various embodiments include a method for checking a sensor for soot particles in exhaust of an engine comprising: generating a sensor current between a first electrode and a second electrode of the sensor, wherein the first electrode and the second electrode define a gap through which the exhaust gas flows between the electrodes, by applying a difference in potential between the electrodes, wherein soot particles accumulate on the electrodes and, after a dwell time dependent on the preloading of the electrodes with soot particles, they move from a first electrode to the respective second electrode generating a flow of current as a measure of the quantity of soot in the stream of exhaust gas; determining whether a peak in the sensor current is measured after the switching off of the internal combustion engine; and if no peak in the sensor current is measured, flagging the particle sensor as faulty.

In a method for detecting rotational speed of an internal combustion engine (), a sector wheel () which is driven by the internal combustion engine () is scanned, the run of a specific segment of the sector wheel is detected, the duration of said segment-run is measured and a rotational speed value is determined therefrom, the duration of the run a specific segment is re-measured, a relative variation between two consecutive segment-runs is determined and the rotational speed value is determined therefrom.

Method for detecting rotational speed

In a method for detecting rotational speed of an internal combustion engine (), a sector wheel () which is driven by the internal combustion engine () is scanned, the throughflow of a specific segment of the sector wheel is detected, the duration of said segment-throughflow is measured and a rotational speed value is determined therefrom. Additionally, the throughflow of a specific part of the segment is detected before and after determination of the rotational speed value and a gradient of the duration of the partial segment throughflow is determined in order to update the rotational speed value.
