Calibration of diesel and gasoline engines
- Minimization of consumption and emissions
- Controller calibration (e.g. drivability, boost-pressure, idle)
- Complex function parameterization (e.g. air charge, torque structure)
Further application of ETAS ASCMO
- Optimization of valves, sensors and other hardware components
- Acceleration of calculation time and improved accuracy of physically based simulations
- Modeling and calibration of actuators considering transient operating states
- Creation of highly-accurate dynamic models
- Optimization and calibration of many other technical systems such as batteries, gear boxes, hydraulic pump units, electric engines
The main use case is the creation of models describing the behavior of combustion engines based on measurement data. By using the DoE (Design of Experiment) approach to identify the data required to train the model, the effort can be reduced considerably. Easy-to-use ETAS ASCMO enables the task to be performed by anyone involved in the engine development process and is no longer restricted to modeling experts only.
ETAS ASCMO also handles desktop emissions testing, allowing the calibrator to evaluate multiple calibration solutions on the desktop. Emission testing becomes a matter of minutes instead of spending several days on the test bench.
For users of GT-Power or other simulation models, supplementing these models with data-based ETAS ASCMO models explicitly improves the predictive accuracy of emissions simulations, resulting in a reduced number of test runs on the dyno or HiL system for validation.
Other use cases are optimization of hardware components such as injection valves, sensors, or alternators, transient prediction of emissions and fuel consumption for driving cycles or complex function parameterization.
