Due to the deviation of greenhouse gas and pollutant emissions under laboratory and real conditions from passenger vehicles, the European Commission has adopted stricter limit values and the RDE test procedure for the approval of future vehicles. This is why novel methods for the virtual development and optimization of conventional and alternative drive systems are becoming increasingly relevant.

In this project a software for real-time emission prediction based on detailed chemistry in an innovative hardware-in-the-loop environment will be developed. In order to enable a fast and accurate prediction of particle emissions, a soot model for tabulated chemistry is developed. The aim is to be able to calculate the emission formation in real time under all operating conditions. A co-simulation for the complete powertrain simulation will be integrated into the combustion model. A functional mockup interface will be developed for this purpose. Finally, the models are validated in a hardware-in-the-loop environmennt with a real ECU in defindes test cases.
