Abstract:
1. A method for calibrating an engine control system, comprising: a) identifying engine calibration sub-problems for an engine calibration; b) seeding an initial generation for one of the engine calibration sub-problems with known/good individuals; c) optimizing free parameters in the one of the engine calibration sub-problems over a parameter/coefficient scheduling space using a genetic algorithm; d) using penalty functions; e) identifying a next one of the engine calibration sub-problems containing a prior one of the engine calibration sub-problems; f) seeding an initial population of the next one of the engine calibration sub-problems with known/good individuals; g) repeating steps c), d), e) and f) until the engine calibration containing the engine calibration sub-problems is solved; and h) operating an engine control system of a vehicle using the engine calibration.
