Zusammenfassung

Due to the increasing complexity of engines and the limited resources virtual development methods are essential throughout the whole development process. Especially in motorsports, virtual engineering methods can accelerate the development and finally make a difference.
Focusing on the engine a wide portfolio of different simulation approaches ranging from advanced 3D-CFD simulations, for detailed in cylinder analysis, to simplified engine surrogate models, for the highest vehicle system level, is available. The particular requirement for each virtual development tool are mainly related to the investigation goal but selecting a model approach is always making a compromise. In terms of practical engine simulations state-of-the-art 0D/1D approaches are able to close the gap between several demands. The ability to adapt the model complexity in combination with an efficient usage enhanced nowadays the application in the development process of
engines.
0D/1D model approaches are typically first choice for the concept and design investigations but due to the computational speed constraints rarely used for later development phases. As a result it is common to change the model type and use simplified approaches that brings several disadvantages like further modelling effort, loss of physical description and lack of predictability. To counteract the disadvantages this paper gives an insight into a proposed proceeding of a continuous implementation of 0D/1D engine models. Based on a detailed model different engine models are derived. Exemplary applications in a “Hardware-in-the-Loop” – system and in a “Driver-in-the-Loop” – system underline the potential of the model approaches as well the advantage of using virtual development tools.
