Validation and Improvement of MVEM in HIL Simulator
In this master’s thesis, a validation method for engine models in a HIL simulator
is developed. To make the validation automatic, a script has been written in the
programming language Python that executes the engine model in the same way
as the real engine in a test cell at Scania CV. Variables in the model are recorded
in real-time and compared to recordings from the engine test cell. The validation
method handles static as well as dynamic engine model validation. The submodels
in the current engine model that causes the most deviation from engine test cell
data are identified. One of them, i.e. the turbine model, is improved by creating a
semi-physical model of a Variable Geometry Turbine (VGT). Furthermore, future
improvements have been suggested.
