The control of engine is becoming more complicated over the years for balancing clean exhaust gas with high merchantability in addition to the fuel mileage improvement demand today and is controlled by the computer, ECU (Engine Control Unit). As the example of complexes, there are the implementation of Variable Valve Technology, Direct Injection to Gasoline Engine/Common-Rail Injection to Diesel Engine and so on went with the exponential growth of those control targets, and how optimize the control depending on driving conditions will give the large influence on engine performance. Therefore, the decision making work on the optimum value, [ECU Calibration Task], is becoming the large burden of development and making efficient of the development is strongly requested. The [STARS Calibrate] which is [ECU Calibration Tool] for performing the work efficiently is introduced in this paper. This product is joint developed by HORIBA and Ricardo who is global engineering company, and especially its DoE part is coming from their “Efficient Calibration (ηCAL)” tools.
