Hardware-in-the-Ioop simulation (HIL) for production engine development

The demands engine developers face today are increasingly complex. Improved driving comfort in conjunction with stricter legal emissions laws and shorter development times require new innovative technologies and forward-looking methods need to be developed and established. In this regard, the Hardware-In-the-Loop simulation (HiL simulation) at the test bench can make an important contribution to decrease the development times. The following gives an overview on the goals of the HiL simulation as well as the configuration of the HiL test bench at IAV. Furthermore, the used physical models are introduced. Finally, some first measurements of the simulation at the test bench are shown.
