摘要：在动力系统中，汽车变速器是连接动力源和车轮的关键部位。为了提高燃油经济性、降低排放及增强驱动性能，近几年来，许多新的技术已经在变速器领域出现了。本文章首先介绍了不同类型的汽车变速器，并阐述了它们各自独特的控制特点。接着，我们又讨论了在汽车变速器控制上来自三个方面的挑战：校准、转换调度，传感、驱动和电子技术。一直以来，研究人员都在寻找进一步改善系统性能的方法。许多新兴的自动变速器（AT），离合器对离合器转换被用来降低成本和改进包装。这涉及到即将出现的和就要过时的离合器的电子控制，以及它们之间的正时和协调。除了省去转换阀，蓄电池等，离合器对离合器转换也省去了滑行离合器和自由轮，这就大大简化了变速器的机械构造。省去这些设备使离合器对离合器转换的稳定控制成为一种挑战。
1.介绍先进的汽车变速器技术
为了提高燃油经济性，减少废气排放及提高性能，汽车制造商一直都在开发新的动力传动技术。在变速器领域，新兴的技术，如传动比连续变化的无级变速器（CVT），双离合器变速箱（DCT），自动手动的综合变速器（AMT）和电动无级变速器（EVT）已经在由齿轮自动变速器（AT）和手动变速器（MT）居于主导地位的市场上出现了。在众多不同的开发这些新型变速器的技术挑战中，系统动力和控制在提供优越的性能的同时，对实现燃油经济性及排放优势也起到了

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.
