基于车辆能耗状态的济南市道路行驶工况构建
Driving Cycle Construction of City Road Based on Vehicles Energy Consumption in Jinan
摘要
Abstract
A driving cycle was constructed to guide new vehicle development and power-train optimization. Key factors that affect vehicle energy consumption, such as road slope, vehicle transient specific power, and vehicle speed, were analyzed. Taking vehicle energy consumption and road slope into consideration, characteristic values of kinematic sequences were proposed. Then, candidate driving cycles were constructed according to the analysis result of kinematic sequences by using tools such as principal composition analysis and clustering analysis. Finally, the actual driving cycle for Jinan was selected from candidate driving cycles by comprehensive consideration of the correlation coefficient, relative error, and key parameters probability distribution. Results indicate that the average error between characteristic values related to vehicle speed and total samples is within 2. 82% , and the average error between other characteristic values and total samples is within 3. 40% . Therefore, the characteristic values of driving cycle calculated from the presented method can characterize the driving cycle of the real roads in Jinan.关键词
