Abstract (en)
[origin: WO2004074665A1] The invention relates to a method for controlling an internal combustion engine (20) of a certain model in accordance with a finite state machine (12). According to known methods, a possible operating state of the internal combustion engine is first adjusted which is associated with a level n of the finite state machine. In a further level (n+1), subordinate operating states relative to the operating state previously determined are specified by the known method. The aim of the invention is to streamline and simplify methods of the aforementioned type so that they can be adapted to control different models of internal combustion engines. For this purpose, the method and the finite state machine are designed in such a manner that the finite state machine comprises at least two groups of levels, the first group representing levels of operating states which the internal combustion engine of a certain model shares with internal combustion engines of a different model, and the second group of levels representing operating states which are specific for the internal combustion engine of a certain model.
