基于最佳碳排放与油耗最优化的行驶车速区间研究

Research on Driving Speed Range Based on Optimum Carbon Emission and Fuel Consumption Optimization

在碳排放实验的基础上,文章研究了CO2排放比例与行车速度之间的关系,并提出最佳碳排放行驶车速区间这一概念。文章结合前人提出的油耗与车速模型,建立了高速公路最优车速区间的计算模型,车辆在此区间上行驶时,油耗低并且燃油充分,即CO2排放比例高。利用面积法确定了最优行驶车速区间的计算方法,求得了这一车速区间,从而达到经济效益与社会环境效益的最大化,同时也能够为高速公路的运营管理提供理论支撑。

Based on the carbon emission experiment,the relationship between CO2 emission ratio and driving speed was studied and the concept of optimal carbon emission driving speed range was proposed.Combining with the fuel consumption and speed model proposed by predecessors,the calculation model of the optimal speed range of freeway is established.When the vehicle runs in this interval,the fuel consumption is low and the fuel is full,which means the CO2 emission ratio is high.Using the area method to determine the optimal driving speed interval calculation method,obtained the speed range.So as to achieve the maximization of economic benefits and social environmental benefits,and at the same time,it can provide theoretical support for the operation and management of expressways.
