Engine control: task modeling and analysis

Engine control is characterized by computational activities that are triggered by specific crankshaft rotation angles and are designed to adapt their functionality based on the angular velocity of the engine. Although a few models have been proposed in the literature to handle such tasks, most of them are quite simplistic and do not allow expressing features that are presently used by the automotive industry. This paper proposes a new task model for expressing realistic features of engine control tasks and presents a sufficient real-time analysis for applications consisting of multiple engine control tasks and classical periodic/sporadic tasks scheduled by EDF.
