基于MATLAB平台下小汽车燃料消耗的仿真及评价

Simulation and evaluation of vehicle fuel consumption based on MATLAB platform

经济的增长伴随着城市化的不断加重,致使城市规模的爆炸性增长,在城市人口与规模增长到所承受最高值之前,对城市的改造成为重中之重。其中,交通能源问题是城市的核心与重点,是保证城市功能照常运行的关键,更是决定城市居民生活水平的重要因素。怎样克服城市因地理结构形态的不同形成的交通特征差异,以确保城市交通的正常运行,是我们正在研究的问题,同样地,掌握车辆在城市的运行过程中的环境情况以及燃料消耗规则,从而减少交通系统能源消耗保证城市环境也具有极其重要的意义。本文通过MATLAB软件特征建立仿真评价系统,再按照实验数据的内嵌完成陕西省西安市区道路的仿真行驶情况,建立起轿车仿真模型,最后获得了仿真运行所得的燃料消耗仿真数据,从而证实了仿真方式评价城市道路轿车的燃料消耗是可行且有效的。

The economic growth is accompanied by the increasing urbanization, resulting in the explosive growth of the urban scale, urban population and scale growth to the highest value, the transformation of the city has become the top priority. Among them, the traffic energy is the core and key of the city,is the key to ensure the functioning of the city as a whole, but also an important factor to determine the living standards of urban residents. How to overcome the city due to traffic characteristics of different formation of geographical differences in structure, to ensure the normal operation of the city traffic, which is the issue we are studying, similarly, grasp the environmental conditions in the operation process of the vehicle in the city and fuel consumption rules, thereby reducing the energy con- sumption to ensure the city traffic system environment also has an extremely important significance. This paper establishes a simulation e- valuation system by MATLAB simulation software, according to the experimental data of the Shaanxi province Xi＇an City Road in the car driving conditions,establish simulation model,finally obtained the simulation run the fuel consumption simulation data,which proves the simulation evaluation of city road car fuel consumption is feasible and effective.
