摘要:This specification discloses a method for adaptively controlling enginecalibration control values. The strategy includes the steps of (1) predicting a drivingpattern based on analysis of recent past driving patterns and (2) selecting engine controlvalues appropriate for the predicted driving pattern and a desired emission constraint.The adaptive strategy adjusts spark timing and magnitude of EGR as a function of engineenergy usage per distance traveled while maintaining feedgas emissions at a constantlevel over a wide variety of driving patterns including urban, suburban and highway. Aplurality of driving cycle segments are analyzed to generate a table of engine calibrationcontrol values for the adaptive spark and EGR control strategy. This adaptive strategyhas fuel consumption characteristics which are most advantageous at the most
constrained feedgas levels. Drivability can be enhanced because of the greater calibrationflexibility inherent to the adaptive technique.
