摘要

根据增程式电动汽车传动系统的工作模式,计算得到发动机特性map和电池系统特性,基于传统的动力学方程,运用Matlab建立了传统系统的各个工作模块,对建立的模型进行分析,并使用遗传算法对RES系统的开启-关闭区域进行了优化处理。仿真结果表明,控制策略改善了SOC的波动范围,并提高了整车系统的燃油利用率。

Abstract

Based on the working modes of the transmission system of range-extended electric vehicle,the map of internal combustion engine and battery system characters are obtained through calculation,the main components of transmission are set up in Matlab on the basis of dynamics equation,and the model is analyzed,the genetic algorithm is combined into control strategy in order to optimize the start-close area of range extended system.The simulation results show that the optimized strategy can not only improve the fluctuation range of SOC,but also improve the fuel consumption of transmission system.
