Abstract

Claims (11)

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.

2. The method of claim 1 wherein the penalty functions are used to ensure a stable, non-oscillatory solution to said engine calibration sub-problems.

3. The method of claim 2 further comprising using weighting to control performance.
