摘 要
混合動(dòng)力汽車兼顧了傳統(tǒng)汽車和純電動(dòng)汽車的優(yōu)點(diǎn),是目前最具可行性的低油耗、低排放汽車?,F(xiàn)有的混合動(dòng)力汽車若采用手動(dòng)變速器傳動(dòng),其性能受駕駛員個(gè)人習(xí)慣所影響,采用自動(dòng)變速器可減小不同駕駛員駕駛同種車輛時(shí)整車性能差異。對于配備了電控機(jī)械自動(dòng)變速器(AMT)的輕度混合動(dòng)力汽車,由于可利用 ISG 電機(jī)的輔助工作能力,從而提高換擋品質(zhì),改善整車的舒適性。
本文以配備了 AMT 的 ISG 型輕度混合動(dòng)力汽車為研究對象,對車輛的換擋過程,即換擋時(shí)間的長短進(jìn)行了研究。主要工作內(nèi)容如下:
①采用插值和擬合的方法,建立了相應(yīng)的數(shù)值模型。對ISG 電機(jī)的工作原理進(jìn)行了分析,并建立了相應(yīng)的數(shù)學(xué)模型。
②對換擋執(zhí)行機(jī)構(gòu)和整車換擋過程進(jìn)行了分析,預(yù)估了換擋時(shí)間。建立了整車的換擋仿真模型,并進(jìn)行換擋過程的仿真分析。
③針對影響換擋時(shí)間的主要因素,提出了利用 ISG 電機(jī)來縮小離合器主、從動(dòng)盤轉(zhuǎn)速差,從而提高輕度混合動(dòng)力 AMT 車輛換擋品質(zhì)的控制策略。
綜上所述,本文對ISG型輕度混合動(dòng)力AMT汽車進(jìn)行了理論分析和仿真研究為研發(fā)輕度混合動(dòng)力 AMT 汽車提供了理論及試驗(yàn)基礎(chǔ)。

ABSTRACT
Hybrid electric vehicle is very feasible, economic and clean by congregating the advantages of conventional vehicle and electric ones. The performance of HEV is influenced by driver’s driving habits if it is equipped with manual transmission. Using automatic transmission can reduced the difference between drivers in the same car efficiently. ISG motor can be used to give a support to meliorate the comfort of driving by improving the shift quality.
This paper focus on the ISG type mild HEV equipped with AMT, considering
about the shifting dynamic performance, driving comforts and parts’ durability, have
done some research described as following.
①The power source simulation model has been established to control it efficiently.
The experiment data of engine and battery also has been analyzed to model them by
interpolation and matching.
②The shifting actuator structure and shifting process have been studied to estimate
the shifting time. The complete vehicle simulation model has been established by
combining the power source, clutch, transmission models and so on. Using this vehicle
model, the simulation analyze about shift quality can be prosecuted to get the most
quality infective process and factors.
③Then the paper aimed at the factors and proposed an optimized control strategy
by using ISG motor to reduce the rotating speed difference between clutch’s plates to
improve the shift quality.
All in all, this paper has done some research on ISG type mild HEV equipped with
AMT, and provided basement of theory and testing for AMT sample vehicle research.
