中文摘要： 乘用车出行路径选择的不同会带来油耗和排放的较大差异，而目前导航系统的路径规划往往以距离和时间最短作为优先选择，但两者并不一定是油耗和排放最低的路线，面临的主要问题是传统的油耗和排放模拟没有考虑与实时路况耦合的需要、最优路径规划没有考虑油耗和排放的差异等。为此，本项目拟通过实际道路车载测试实验，分析道路及行驶特征对乘用车油耗和排放的影响机理；构建综合考虑车速、加速度和道路坡度的基于VSP的油耗和排放模型，并分析四种等级道路不同车速范围内VSP的分布规律，研究基于实时路况的出行路径油耗及排放模拟方法；以路段和交叉口的油耗和排放值作为权值，采用增量式D* 算法作为路径搜索算法，结合驾驶模拟实验平台通过仿真实验完成路径规划，并构建车载导航实验平台通过道路试验对算法进行改进。研究为基于实时路况信息在给定的数字地图中寻找从出发地到目的地的最优油耗及排放路径，开发乘用车经济环保出行路径导航系统奠定基础。

英文摘要： Different travel routes of passenger vehicles will bring huge differences in energy consumption and emissions, the current route planning in vehicle navigation system often takes routes of the shortest distance, shortest time as the preferred option, but both are not necessarily the lowest energy consumption and lowest emission paths. The main problems are such like, traditional energy consumption and emission model are not suitable for coupling with real-time traffic operation, the optimal route planning does not take account of differences in energy consumption and emission. Therefore, this project intends to analyze the mechanism by which road characteristics and driving characteristics affect passenger car energy consumption and emissions; this project will built a VSP-based energy consumption and emission model which contains speed, acceleration and road slope, and analyze the VSP distribution in different speed ranges of four road grades, and study travel routes energy consumption simulation and emission simulation based on real-time traffic operation; this project puts energy consumption and emission values on road and interaction as weights, uses incremental D * algorithm as the search algorithm for an optimal path, achieves route planning through driving simulation experiment platform and improves the algorithm through on-board navigation system test. Based on the real-time traffic operation, this research is to investigate an optimal energy consumption route and an optimal emission route from origin to destination in a given digital map, thus lay a theoretical basis for the development of economical and environment-friendly route navigation system.
