US Patent 7440837 Mechanism for interconnecting independent functionalities of an engine controller

Electronic engine controllers contain a multitude of individual components that, in part, trigger one another. Until now, a change made to these trigger connections required a change, for example, in the source code of the engine controller. According to the invention, all trigger connections are realized by interconnecting wrappers, which receive the trigger signal from a component and—optionally after translating the trigger signal into a trigger signal of a differing type route this trigger signal to the second component to be triggered. In order to produce or change a trigger connection, it is only required to change the configuration of the wrappers.
