【摘要】：文章針對(duì)增程式電動(dòng)汽車增程器燃油經(jīng)濟(jì)性和CO、HC排放問(wèn)題進(jìn)行優(yōu)化。首先,將問(wèn)題利用歸一化和加權(quán)平均的方法轉(zhuǎn)化為單一目標(biāo)問(wèn)題,以增程器外特性、功率區(qū)間需求和其他特性參數(shù)作為約束條件,利用MATLAB軟件基于map圖進(jìn)行建模和仿真,使用改進(jìn)的差分進(jìn)化算法予以實(shí)現(xiàn)。最后,在AVL Puma Open臺(tái)架實(shí)驗(yàn)平臺(tái)上對(duì)HWFET工況下的增程器燃油經(jīng)濟(jì)性和CO、HC排放運(yùn)用文章所提出的策略進(jìn)行實(shí)驗(yàn)驗(yàn)證。實(shí)驗(yàn)結(jié)果表明,以增程器的燃油經(jīng)濟(jì)性和CO、HC排放為目標(biāo),可以實(shí)時(shí)精確地控制發(fā)動(dòng)機(jī)轉(zhuǎn)速、發(fā)電機(jī)轉(zhuǎn)矩,有效實(shí)現(xiàn)降低整車油耗和排放。
[Abstract]:In this paper, the fuel economy and CONHC emission of range booster of extended range electric vehicle are optimized. Firstly, the method of normalization and weighted average is used to transform the problem into a single objective problem. The external characteristics of the range adjuster, the power interval requirements and other characteristic parameters are taken as the constraint conditions, and the MATLAB software is used for modeling and simulation based on the map graph. The improved differential evolution algorithm is used to implement it. Finally, on the AVL Puma Open bench platform, the fuel economy and the strategy proposed in the paper are verified. The experimental results show that the engine speed and generator torque can be accurately controlled in real time by taking the fuel economy and CONHC emission of the range booster as the target, and the fuel consumption and emission can be effectively reduced.
