基于仿真技术的汽车能耗与质量关系的研究

Simulation–Based Study on Relationship of Auto Mass and Fuel Reduction

为了研究汽车能耗和汽车质量之间的关系,本文首先建立了仿真的目标,即以内燃机驱动、混合动力驱动和氢燃料驱动的车辆为研究对象,对这3种不同的研究对象又分别选取了3种类型的车辆。根据仿真目标建立了汽车仿真模型,并在MATLAB/SIMULINK环境下实现。仿真结果表明,汽车能耗随着质量减少而减少,驱动方式、车型、传动等因素对油耗也有很大的影响。

Simulation objects including internal combustion engine driving, mixed power driving and hydrogen battery power driving were decided to analyze the relationship of the auto mass and fuel reduction, with three cars for each driving model. A model car was established, and the simulation is realized in Matlab/Simulink. The result of the simulation shows that fuel consumption is less when the car is lighter, and the relationship of auto mass and fuel reduction is complex, influenced by parameters such as driving method, transmission, etc.
