Recent developments in the EU introduce a new emissions testing procedure called real-driving-emissions (RDE). The tests are taking place on public roads and within "real" surroundings, to deliver more realistic results. These changes are causing some challenges due to the hardly reproducible test conditions. A solution can be found by using an improved chassis dynamometer, which replicates the environmental influences in a realistic way. Especially emissions and fuel consumption must be well reproducible. This paper shows the current status of the investigations to determine the necessary extensions and modifications to existing chassis dynamometers.

21 physical parameters occurring during on-road driving within "real surroundings", influencing exhaust emissions and fuel consumption, were found and analyzed with the aid of theoretical investigations. Based on those findings, comparative tests were performed with a Plug-In-Hybrid vehicle, showing the potential of reproducing on-road driving on a chassis dynamometer. Exemplarily, further results are shown and discussed, indicating differences between on-road driving and testing on a chassis dynamometer.
