Abstract

X-in-the-Loop simulations enable the prediction of interactions between virtual or real components during transient operation and allow early system integration and testing in the vehicle development process. According to the concrete applications, the models used must achieve a compromise between model accuracy, modelling effort and computational effort. The one-dimensional simulation of internal combustion engines allows physical and causal modelling of the air path. Its integration in the X-in-the-Loop simulation is the focus of the dissertation. A basic model design to enable real-time capability is presented followed by the model calibration process and the validation results using measurement data. Detailed feasibility studies on application examples for system design and function development based on model-in-the-loop simulation as well as engine control unit application based on hardware-in-the-loop simulation along with system-wide validation results are among the most important contributions of this dissertation.
