摘 要

混合動(dòng)力汽車是當(dāng)前最具可行性的環(huán)保節(jié)能型汽車，成為汽車行業(yè)研究的熱點(diǎn)之一。由于混合動(dòng)力汽車具有兩套動(dòng)力源，動(dòng)力分配及能量管理比較復(fù)雜，因此，在混合動(dòng)力汽車基本結(jié)構(gòu)及其參數(shù)確定后，整車控制策略可以通過發(fā)動(dòng)機(jī)和電機(jī)的動(dòng)力分配，使得發(fā)動(dòng)機(jī)工作在低油耗、低排放的區(qū)域，避開發(fā)動(dòng)機(jī)怠速等高油耗區(qū)域，從而實(shí)現(xiàn)整車燃油經(jīng)濟(jì)性的提高和排放的改善。因此，研究混合動(dòng)力汽車控制策略對(duì)充分發(fā)揮其節(jié)油環(huán)保優(yōu)勢具有十分重要的意義。
本文以ISG型混合動(dòng)力汽車為研究對(duì)象，對(duì)驅(qū)動(dòng)工況下的ISG型混合動(dòng)力汽車控制策略進(jìn)行了研究，并對(duì)其進(jìn)行了二次開發(fā)。

ABSTRACT

Hybrid electric vehicle is the most feasible clean economical vehicle which becomes one of the research hotspot in automotive industry at present. But it’s complicated to distribute the power and manage the energy because the hybrid electric vehicles are always drove with two different power sources. When the basic configuration and parameters are confirmed, the control strategy of hybrid electric vehicle will optimize the internal combustion engine operation to improve the fuel economy and emission performance, through optimizing the power flow distribute engine and motor. Therefore, the research on control strategy is very important to exert the advantages of hybrid electric vehicle.
Using the ISG hybrid electric vehicle as the research object, the control strategy of ISG hybrid electric vehicle at drive condition was researched and done second development about it.
The numerical model of hybrid electric vehicle was built firstly in this paper. Based on the data of engine, ISG motor and NiMH battery, the numerical model of each power assembly was accomplished through analyzing the data. Then, the operation models of ISG hybrid electric vehicle were analyzed, and the best control strategy for hybrid electric vehicle at drive condition was built based on the numerical model aiming at the minimum equivalent fuel consumption.
Based on the analysis of modeling process for ADVISOR software, control strategy for ISG hybrid electric vehicle (insight) was read and analyzed. Through this, we can know about control strategy with motor assist.
At last, based on ADVISOR and the data that this paper provided, the second development was done about ISG hybrid electric vehicle. The simulation about ISG hybrid electric vehicle was done at some condition. From the simulation, we can know that the minimum equivalent fuel consumption is achieved.


Keywords: Hybrid electric vehicle, control strategy with motor assist, ADVISOR software, equivalent fuel consumption
