Recently, considerable effort has been devoted to improving vehicle fuel efficiency and emissions during real road trips. An analysis of vehicle driving energy is typically based on vehicle dynamics, and it has been very effectively used for the analysis of vehicle operation, brake down analysis of the required energy, prediction of vehicle performance, and vehicle control design. In this work, on the basis of the results of driving and powertrain operation analyses performed for diesel sport utility vehicles, a new trip unit of CO2 emission and NOx emission model that reflects real road operating conditions such as the coolant temperature and engine and vehicle efficiency changes is presented. In particular, the developed model does not require detailed powertrain specifications and performance maps, and is constructed to enable simple configuration, easy utilization, and extended application. The model was verified by comparing its results with those of the National Institute of Environmental Research (NIER) driving mode test, which is a domestic vehicle driving mode test, and with the results of an actual road driving analysis. Finally, a model analysis of energy consumption factors for different vehicle speeds on real roads is presented.
