摘要：在動力系統(tǒng)中，汽車變速器是連接動力源和車輪的關(guān)鍵部位。為了提高燃油經(jīng)濟(jì)性、降低排放及增強(qiáng)驅(qū)動性能，近幾年來，許多新的技術(shù)已經(jīng)在變速器領(lǐng)域出現(xiàn)了。本文章首先介紹了不同類型的汽車變速器，并闡述了它們各自獨特的控制特點。接著，我們又討論了在汽車變速器控制上來自三個方面的挑戰(zhàn)：校準(zhǔn)、轉(zhuǎn)換調(diào)度，傳感、驅(qū)動和電子技術(shù)。一直以來，研究人員都在尋找進(jìn)一步改善系統(tǒng)性能的方法。許多新興的自動變速器（AT），離合器對離合器轉(zhuǎn)換被用來降低成本和改進(jìn)包裝。這涉及到即將出現(xiàn)的和就要過時的離合器的電子控制，以及它們之間的正時和協(xié)調(diào)。除了省去轉(zhuǎn)換閥，蓄電池等，離合器對離合器轉(zhuǎn)換也省去了滑行離合器和自由輪，這就大大簡化了變速器的機(jī)械構(gòu)造。省去這些設(shè)備使離合器對離合器轉(zhuǎn)換的穩(wěn)定控制成為一種挑戰(zhàn)。
1.介紹先進(jìn)的汽車變速器技術(shù)
為了提高燃油經(jīng)濟(jì)性，減少廢氣排放及提高性能，汽車制造商一直都在開發(fā)新的動力傳動技術(shù)。在變速器領(lǐng)域，新興的技術(shù)，如傳動比連續(xù)變化的無級變速器（CVT），雙離合器變速箱（DCT），自動手動的綜合變速器（AMT）和電動無級變速器（EVT）已經(jīng)在由齒輪自動變速器（AT）和手動變速器（MT）居于主導(dǎo)地位的市場上出現(xiàn)了。在眾多不同的開發(fā)這些新型變速器的技術(shù)挑戰(zhàn)中，系統(tǒng)動力和控制在提供優(yōu)越的性能的同時，對實現(xiàn)燃油經(jīng)濟(jì)性及排放優(yōu)勢也起到了

Abstract:
Automotive transmission is a key element
in the powertrain that connects the power source to
the wheels of a vehicle. To improve fuel economy,
reduce emission and enhance driving performance,
many new technologies have been introduced in the
transmission area in recent years. This paper first
reviews different types of automotive transmissions
and explains their unique control characteristics. We
then address the challenges facing automotive
transmission control from three aspects: calibration,
shift scheduling, and sensing, actuation and
electronics. Along the way, research opportunies to
further improve system performance are discussed.
1. Introduction to the Latest Automotive
many of the new automatic transmissions (AT),
clutch-to-clutch shift is adopted to reduce the cost and
improve packaging. This involves electronic control of
both the oncoming and offgoing clutches and the
timing and coordination between them. In addition to
eliminating the shift valves, accumulators, etc., clutch-
to-clutch control eliminates the coasting clutches and
freewheelers, greatly simplifying the transmission
mechanical content. The absence of these devices
makes the robust control of clutch-to-clutch shifts a
challenge.
