Abstract:
A method for automatically generating smoothed characteristic diagrams for electronic engine controls on piston-type internal combustion engines, characterized in that on a reference piston-type internal combustion engine, the adjustment variable combination of the individual, successive operating points is input by means of an engine control and by specifying desired values for the marginal operating conditions of a piston-type internal combustion engine, that the piston-type internal combustion engine is driven at this operating point and the resulting actual values and/or marginal conditions are detected and are compared to the desired values for the marginal conditions in an optimization system that is assigned to the engine control and that in case of deviations, the adjustment variable combinations are changed and optimized step-by-step with the optimization system, wherein a quality function for the respective change in the adjustment variable combination is predetermined in the optimization system, and that the quality function is corrected, respectively by taking into account already fixed values for the adjustment variable combination of at least one neighboring operating point.
