- Abstract
- This is a precedent study for the development of real road driving mode that has a similar NOx emission trend to that of the KD-147 test mode, which is a vehicle periodic test mode in Korea. The vehicle specific power, acceleration, and velocity were defined as driving parameters that have a significantly high effect on NOx emission, and the correlation between each parameter and NOx emission were analyzed. In the case of acceleration and velocity, we tried to analyze the independent effect of each parameter on NOx emissions by adjusting another driving parameter. Experimental results show that the defined driving parameters have a significant correlation with NOx emissions and several guidances of real road driving mode were proposed in order to yield similar NOx emission results of the KD-147 test mode based on the results of the study.
