Aim of the study is the automated computation of exhaust gas emissions from timerelated measuring data sets. For the determination of the exhaust gas emissions in real world conditions, the test vehicle was equipped with a new On Board Measurement (OBM) system. The raw data provided by the OBM must be post processed to describe the vehicle performance. It is required to find out faulty data sets, to correct them, then to calculate necessary variables and to draw diagrams. In order to decrease the required time, all of these procedures have been automated. The data sets coming from the OBM system and the experimental data achieved during the driving tests are used to compute exhaust gas emissions, the driving resistance, characteristic engine curves, fuel consumption et. All of these computations were automated using a website script interface in Matlab Simulink. For the identification and correction of the erroneous measured data, m-files with Matlab code were also written. As a result of this post-processing calculation several diagrams has been implemented. It is important to visualize gained information with diagrams, for this reason the procedures to obtain necessary diagrams were also automated. It can be concluded that the use of automated functions enables a more efficient study of the vehicle performance from real-world data. The real-world measurements of an Opel Zafira 1.6 CNG ECOTEC with manual gearbox were used as a sample to calculate the engine characteristic maps. Nevertheless, the application of the calculation program can be used for other test vehicles including Hybrid powertrains.
