- Abstract:
- In the process of driving cycle construction,experimental data ’s analysis and processing will di-rectly affect the accuracy of driving cycle. Due to the complexity of urban road traffic structure and vehicle ’sspecial operating mode,fuzzy clustering method is introduced to analyze vehicle ’s typical motion data of Xi’an urban road traffic in order to establish driving cycle which is closely related to vehicle’s running state androad traffic flow. After average speed and speed standard deviation fuzzy clustering,following results arefound,sedan’s driving states on Xi’an urban road are divided into congestion running state ,steady flow run-ning state and free flow running state three categories. Furthermore,combining classification method withshort-stroke method,sedan ’s representative driving cycle in Xi ’ an city is built and verified. The resultshowed; the relative error between Xi’an representative driving cycle constructed by furzy clustering methodand experimental data is small,which would reflect the vehicle’s actual running state.
