Development of Car Drive Cycle for Simulation of Emissions and Fuel Economy

This paper describes the development of car drive cycle for simulation of vehicles exhaust gas emissions and fuel economy. In this research work, the development of light vehicle drive cycle for city of Tehran has been performed. First, the approach to develop a drive cycle has been described. The necessary measuring tools and software have then been provided, and the car speed has been recorded in the city traffic condition. Based on the analysis of the recorded data, a drive cycle has been developed for city of Tehran. Applying the statistical analysis, the cycle has then been modified, and a real world smoothed cycle has been presented. Finally, characteristics of this cycle have been compared with some of light vehicles cycles provided for other countries.
