시내버스 연비평가를 위한 주행모드 개발의 필요성에 관한 연구

Foreign countries are actively developing driving cycles of a bus. In the case of City Bus, there are no driving cycles for fuel consumption test in korea which are considering road conditions and driving patterns. In this paper, the Central Business District(CBD) and New York Bus(NY Bus) driving cycles which have representatively been used in USA were analyzed to consider an alternative driving cycle in korea. The parameters of representative driving cycles were compared with domestic driving patterns which collected during on road operation within the city in Seoul. The results showed that the average velocity, idle times and acceleration of domestic driving were different from those of the CBD and NY Bus cycles. Fuel economy levels also were not similar to those of the CBD and NY Bus cycles. The representative driving cycles are not fit to test fuel economy of domestic buses. This paper discusses the necessity of the city bus driving cycle considering the road conditions and driving pattern to estimate fuel economy in korea.
