Automated System for Optimized Calibration of Engine Management Systems 940151

Due to the stringent emission standards modern engine concepts require special equipment for reducing exhaust pollutants and minimizing fuel consumption. Usually all those engine functions are managed by an electronic engine control unit (ECU).
A good potential for emission reduction is dependent on a well optimized set of calibration maps, tables and constants, contained in the ECU. The time to evaluate an optimum data design strongly depends on the number of these calibration parameters. With an increasing number of such parameters, there is a need for sophisticated test systems which automatically initiate parameter variations, perform necessary measurements and search for an optimized engine calibration.
VEGA is an automatic optimization system that controls the whole calibration process from the first basic mapping until the final programming of the ECU. It performs much faster and, following exact mathematical algorithms, results in better reproducibility than with manual optimization.
The time required for an automatic operation depends on the Optimization-Algorithm and the chosen parameters. Various results are shown and discussed.
