ABSTRACT:
This specification discloses a method for generating an engine energy output signal for use by an adaptive strategy in controlling the performance of a spark ignited automobile combustion engine. An estimated future energy output combines the weighted sum of a short term energy output average, a medium term energy output average and a long term energy output average. The adaptive strategy adjusts spark timing and distance of EGR as a function of engine energy usage per distance traveled while maintaining feedgas emissions at a constant level over a wide variety of driving patterns including urban, suburban and highway. This adaptive strategy has advantageous fuel consumption characteristics which are greatest at the most constrained feedgas levels. Drivability can be enhanced because of the greater calibration flexibility inherent to the adaptive technique.
