A Research on Driving Cycle for Electric Cars in Beijing

In this paper, the driving cycle for electric cars in Beijing is investigated. Firstly a reasonable experimental scheme is made, in which several electric cars are selected and a new type of data collection transmission and management system based on GPRS communication is used. Then the obtained data is preprocessed and divided into microtrips, and many characteristic parameters are selected. Finally, a representative driving cycle of electric cars for the typical roads in Beijing is worked out by principal component analysis and k-means clustering method. And compared with the test data, the results show that the fitted driving cycle can represent the overall traffic condition of electric cars in Beijing.
