基于驾驶员驾驶习惯的增程式电动汽车参数匹配研究

Study on Parameters Matching of Extended-Range Electric Vehicle Based on Driver's Driving Habits

纯电动汽车由于电池低能量密度导致续驶里程短,高价格导致用户购买力低,增程式电动汽车(EREV)通过增加增程器(发动机-发电机组)克服了这一缺陷,基于驾驶员的驾驶习惯分析了增程式电动汽车的性能,并对动力传动系统参数进行匹配,基于Cruise仿真软件对增程式电动汽车进行仿真分析,仿真表明,匹配的动力系统参数完全满足要求。

Batteries for electric vehicle have limitations,such as low energy density and high price,which causes short driving distance and low purchasing power. Extended-Range Electric Vehicle( EREV) will overcome the shortages by adding extended-range device( internal combustion engine and generator). EREV's performance index were analyzed based on driver's behavior in this paper. Power-train parameters of EREV were matched and simulated based on cruise simulation software. The results showed that power train parameters can meet the requirements for applicaiton.
