Abstract :
The control of emissions has been addressed in the past to comply with environmental regulations. In particular air-to-fuel ratio control is key to reach the allowed pollution levels. The aim of this work is to present an alternative approach which allows for more flexibility to account for the type of signals and requirements of automotive applications, specifically, handling of time and event triggered tasks. An air-fuel ratio nonlinear controller is developed for an automobile engine. The controller is then implemented using the event-driven real-time programming language xGiotto on the OSEK platform provided by WindRiver. Special attention is given to show the advantage that can be gained from using an event driven paradigm for implementing automotive controllers.
