考虑换道轨迹的车辆油耗模型改进
Improvement of Vehicle Fuel Consumption Model for Vehicles with Changed Lane Tra-jectories
摘要
Abstract
In the traffic flow established based on the cellular automata model,through the analysis of vehicle lane-changing behavior,it can be known that the cellular lane-changing behavior does not match the actual lane-changing situation,resulting in deviations in the calculated fuel consumption values.In this study,the isokinetic offset-sinusoidal combined lane-changing model is adopted to recalculate the length of the vehicle lane-changing trajectory to improve the calculation accuracy of the fuel consumption model.The calculation results of the improved fuel consumption model show that as the vehicle density increases,the average fuel consumption per 100 kilometers of the vehicle presents a U shape,and the vehicle density has a quintic polynomial relationship with the fuel con-sumption value.The calculated fuel consumption value is 0.8～1.7 percentage points higher than that of the tradi-tional model.The simulation calculation results show that the optimal economic speed of the vehicle on the express-way is stably between 55～80 km·h-1,and the fuel consumption under road congestion and high-speed driving condi-tions is slightly higher than that under other driving conditions.The calculation results of the fuel consumption mod-el based on the constant-speed offset-sinusoidal combined lane-changing trajectory verify that the calculated values of the improved model are more in line with reality and the results are more accurate.关键词
