摘 要

隨著能源和環(huán)境對(duì)人類生活和社會(huì)發(fā)展的影響越來(lái)越大，要求盡快改善人類生存環(huán)境的呼聲日益高漲。為此，各種電動(dòng)汽車脫穎而出，但由于蓄電池的能量密度與汽油相差很大，遠(yuǎn)未達(dá)到所要求的數(shù)值，而燃料電池技術(shù)亦尚未取得重大突破。 在這種情況下，融合內(nèi)燃機(jī)汽車和電動(dòng)汽車優(yōu)點(diǎn)的混合動(dòng)力電動(dòng)汽車(HEV)異軍突起，成為當(dāng)前新型汽車開發(fā)的熱點(diǎn)。混合動(dòng)力電動(dòng)汽車是解決環(huán)境污染和能源問(wèn)題最具實(shí)際商業(yè)前景的清潔汽車。

ABSTRACT

As the stress of oil source scarcity and deterioration of urban environment become more and more severe, it is urgent to seek a new technology of saving energy and reducing the exhaust emission. Electric vehicle (EV) seems to be the best method to solve these problems, but its development is currently limited by battery’s low energy density . Fuel cell electrical vehicle (FCEV) is just on the laboratory level . On this occasion , hybrid electric vehicle (HEV) which have the merits of EV and conventional vehicle (CV) is invented, HEV investigations on become a new hotspot in international automobile field. HEV is regarded as one of the most realistic method to improve urban environment and relieve the stress of oil source scarcity.
The options of HEV Powertrain Schedule and Powertrain components are discussed in this thesis. As a conclusion, integrated starter/alternator mild HEV(ISG-MHV) which is suitable to mini car is put forward. The control strategy of idle-stop, power assist, engine drive lonely, power regeneration, friction brake are anslysed. In addition , some simulink modules of ADVISOR are modified according to the Powertrain Schedule ,control strategy and working mode of ISG-MHV in this thesis. Based on theoretical analysis and relative reference, the parameters designing method of the ISG-MHV powertrain components including ISG, engine, battery and gearbox are presented . The dynamic performance and fuel economy on the ECE+EUDC driving cycle are simulated by ADVISOR software. Compared with the conventional vehicle (CV) of similar dynamic performance, the fuel economy of the ISG-MHV increase above 11%, which prove the merit of ISG-MHV on fuel economy .


Key words：ISG, HEV, matching, simulation
