ABSTRACT |
Recently, there has been increasing interest in reducing hazardous and CO2 emissions from vehicles. For
emission reduction, it is necessary to analyze operating conditions of vehicles by using real on-road data and to improve their
effective performance. In particular, for heavy-duty vehicles, technical improvements and operational management are
critical in terms of air quality management, for although the number of vehicles is small, the duration and level of emissions
are relatively high. However, research data obtained from analyses of driving characteristics of heavy-duty domestic delivery
vehicles are relatively insufficient. Technically, there are many difficulties in setting driving conditions for such analysis,
such as measuring driving resistance and determining variations in the vehicle mass with the amount of freight. In this study,
on the basis of the speed and engine output data of a heavy-duty gas delivery tractor obtained during real road driving, the
driving characteristics of the vehicle was analyzed, its weight was estimated, and the effect of the vehicle’s weight on the
driving energy and vehicle output was investigated. |
