Abstract:
1. A method for executing tasks for an internal combustion engine comprising two control devices each operable to process tasks independently of the other, the method comprising: adjusting operating parameters of the engine, wherein an adaptive adjustment is performed only by one of the two control devices at a time, wherein adjusting the operating parameters comprises: checking whether a first adaptive task is to be executed by the first control device; if the first adaptive task is to be executed, maintaining an active level for a first release signal associated with the first control device and an inactive level for a first switchover signal associated with the first control device during execution of the first adaptive task; upon completion of the first adaptive task, reducing the first release signal to the inactive level and increasing the first switchover signal to the active level; receiving the first release signal and the first switchover signal at the second control device; and interpreting the inactive level first release signal and the active level first switchover signal as permission to implement a second adaptive task at the second control device; wherein the two control devices cooperatively control respective engine actuators.
