How Manual Transmissions Work by Marshall Brain If you drive a stick-shift car, then you may have several questions floating in your head. How does the funny "H" pattern that I am moving this shift knob through have any relation to the gears inside the transmission? What is moving inside the transmission when I move the shifter? When I mess up and hear that horrible grinding sound, what is actually grinding? What would happen if I were to accidentally shift into reverse while I am speeding down the freeway? Would the entire transmission explode? In this article, we'll answer all of these questions and more as we explore the interior of a manual transmission. Cars need transmissions because of the physics of the gasoline engine. First, any engine has a redline -- a maximum rpm value above which the engine cannot go without exploding. Second, if you have read How Horsepower Works, then you know that engines have narrow rpm ranges where horsepower and torque are at their maximum. For example, an engine might produce its maximum horsepower at 5,500 rpm. The transmission allows the gear ratio between the engine and the drive wheels to change as the car speeds up and slows down. You shift gears so the engine can stay below the redline and near the rpm band of its best performance. Photo courtesy DaimlerChrysler Mercedes-Benz Actros, manual transmission. See more transmission pictures. Ideally, the transmission would be so flexible in its ratios that the engine could always run at its single, best-performance rpm value. That is the idea behind the continuously variable transmission (CVT). A CVT has a nearly infinite range of gear ratios. In the past, CVTs could not compete with four-speed and five-speed transmissions in terms of cost, size and reliability, so you didn't see them in production automobiles. These days, improvements in design have made CVTs more common. The Toyota Prius is a hybrid car that uses a CVT. The transmission is connected to the engine through the clutch. The input shaft of the transmission therefore turns at the same rpm as the engine
不断增加的城市空气污染 经过20年的改革开放，中国私人汽车数量迅速增加，汽车开始进入普通人的家庭生活。汽车需求的迅猛增长是推动2002年中国经济增长的重要力量。去年汽车制造商制造并销售了325万辆，比2001年增长了37%。此外，去年载客汽车的销售首次突破了100万大关，猛增56%，达到了万辆。 2001年后加入世界贸易组织（WTO），中国已经将汽车的进口关税从70-90%降低到44-51%，到2005年将进一步降低到25%。随着汽车价格的下降以及中国人较低的汽车拥有量，中国的汽车市场将会进一步繁荣。 随着轿车进入家庭，主要城市及近郊的交通拥挤状况会进一步加剧，从而使汽车废气排放问题更加严重。中国有2000万辆汽车和1亿辆摩托车，而其中大多数都在城市。在城市环境污染物中，汽车所排放的氮氧化物占到了45至60%，而一氧化碳则占到了85%。因此，中国城市居民所吸入的劣质空气主要是由汽车所排放的废气造成的。 除非政府愿意牺牲这方面的经济支柱产业，限制上路汽车数量。因此，要控制汽车废气排放问题，利用电子技术来减少汽车的废气排放是解决方案之一。 排放标准 2001年底，中国政府宣布对中国三大汽车制造商降低30%的汽车消费税，前提是他们所制造的汽车得满足欧II标准。六个月后，在第三届中国亚洲清洁燃料国际会议上，政府的另一项声明进一步表明了控制汽车排放的决心。声明称，北京将从2003年1月开始对在北京销售的机动车辆实行欧II标准，并计划于2005年实施欧III标准。 要控制废气排放所面临的挑战并不仅仅是要设计一个具有清洁燃烧能力的完美发动机，还要利用合适的半导体电子器件对发动机的燃烧过程进行合理的控制。英飞凌为今天的发动机管理平台提供了所需要的单片机、传感器和功率半导体器件。 用于动力总成系统的半导体器件 为控制废气排放量，可利用半导体传感器来精确测量吸入空气的成份。利用单片机快速计算出所使用的燃料数量，然后再起动燃料喷射器。由于有正确的空气-燃料比，因此可以达到近乎完美的燃烧状态，从而使废气的排放达到最少。 汽车动力总成应用中需要多个传感器来将"真实"环境与电子部分连接起来。基于半导体的传感器专用于测量速度、位置、温度和压力。对于动力总成应用来说，最大的变化趋势是利用集成了传感器单元和信号处理部分的有源传感器来代替过去的被动式传感器。由于需要更精确地测量发动机的状态，因此这一趋势发展很快。 在通过传感器测量到发动机的状态以后，单片机就可以处理这些数据并提供合适的控制信号来控制致动器的动作。单片机是利用逻辑技术制造的，而集成度的提高使得可以将功能强大的处理器与外设集成在一起。目前的趋势是将DSP功能集成进来，从而允许实现更为复杂和精确的信号处理软件算法。这样就可用软件实现以前采用硬件实现的功能。 一旦单片机"知道"下一步该做什么，单片机就发送合适的信号到致动器。通常，致动器需要高电压或者大电流才能动作。因此，需要利用功率半导体器件来驱动致动器，如燃料喷射器或火花塞。过去几年里，功率半导体技术的发展主要集中于优化现有系统的成本和部分集成。这产生了能够集成功率输出级（DMOS或双极）、模拟电路和数字逻辑的混合集成技术（BCD）。高集成度功率器件的优势是可以支持诊断，从而可使系统具有更好的可靠性（动力总成是汽车中的关键应用）。同时，这还可使最终产品所需要的外部器件数量大大降低。 系统解决方案 目前的动力总成电子控制单元（ECU）中，电子器件部分主要是半导体器件。 半导体传感器 传感器位于动力总成系统的前端。传感器用来测量物理参数，如水温、空气压力以及发动机曲轴的转动速度。这些数据非常关键，它们为闭环控制系统提供了关键信息。除了温度传感、压力传感和霍尔传感器以外，微机械技术还带来了崭新的加速和偏向角速度传感器，同时还允许利用标准晶圆制造工艺集成信号处理电路和数字化电路。 1.温度传感器 根据扩展电阻原理，线性和稳定的半导体传感器可低成本地替代镍或铂金属膜传感器，同时还可提供比PTC热电阻技术上更优越的器件。 2.位置和速度传感器 动态差分霍尔IC可以测量曲轴或凸轮轴速度、传动速度和车轮速度。通过使用位于单个芯片上的两个霍尔单元，一个差分放大器和处理电路，可以测量到磁场差。这意味着可以将温度漂移、制造容差和外部电磁环境等破坏性环境影响降到最小。同样的信号水平，与单片机的接口要比采用旧式的有感线圈简单得多、便宜得多。 英飞凌新开发的TLE4925C特别适合曲轴应用。其集成电路（基于霍尔效应）提供了频率与转速成正比的数字信号输出。额外的自校正模块提供最优的精度。利用新的模块型封装所集成的滤波器电容器可以减少干扰。 3.进气管绝对压力/大气绝对压力传感器 在新一代传感器中，复杂的处理电路完全集成在传感器芯片上。随着表面微机械技术得以在标准BiCMOS工艺进行微机械加工，利用其技术制造的传感器称为MEMS(微电子机械系统)。利用微机械技术，可以制作出厚度仅有400 m的多晶硅薄膜。这些薄膜构成在芯片上的多个电容器和两个参考电容器。信号则源于压感区域和参考区域的差别。 由于需要利用模拟的绝对压力传感器来测量进气管绝对压力和大气绝对压力，因此标准BiCMOS技术就特别重要。这是因为需要复杂的电路来提供模拟输出信号，进行线性化和偏差补偿。一个MAP传感器测量进气管中空气的绝对压力，并为发动机管理系统提供一个重要的参数（空气体积）。另一方面，一个BAP传感器则测量环境空气压力（是汽车高度的函数），这也是发动机管理系统所需要的同样重要的一个参数（空气密度）。有了这两个参数，就可算出空气的质量，并利用算出的空气质量来决定喷入多少燃料以实现最佳的燃烧。英飞凌的BAP传感器KP120适用于柴油和汽油发动机的管理。 单片机 单片机是动力总成系统的大脑。实时运行的高度复杂的算法用来在各种情况下管理发动机及传送动作。由于系统位于发动机罩下的恶劣环境中，因此除了合适的CPU以外，单片机的整个系统架构对于系统性能来说非常重要。目前在动力总成应用中使用的CPU架构有8位、16位和32位。 8位架构主要用于非常低端的汽车产品，但在摩托车ECU中的应用前景看起来很好。英飞凌提供低成本的增强8位C500核心，以及适合在成本敏感的摩托车市场中应用的高性能外设。由于相应的软件和工具集与业界标准的80C51单片机完全兼容，因此可加快软件开发周期。 32位单片机的市场份额正越来越大。但是，大批量生产的16位产品仍然在目前的汽车中有很大的市场。英飞凌的16位C167系列旨在满足实时嵌入式控制应用的高性能要求。该系列单片机的架构针对大指令吞吐量和对外部刺激（中断）的快速响应而优化。集成的智能外设子系统可将所需要的CPU干预降低到最低的程度。这还减少了对通过外部总线接口进行通信的需要。C167系列的成功源于其CPU，以及对于动力总成应用的要求来说非常理想的外设组合。 称为C166v2内核的新一代C166内核采用了单时钟周期执行技术，因此性能提升了一倍。内置的高级乘法和累加指令（MAC）执行单元极大地提高了DSP性能。 目前功能最强大的单片机采用了32位CPU。此类CPU中的一些源于单片机架构。而象英飞凌TriCore这样的CPU则是针对实时环境中的嵌入式控制应用而设计的，因此非常适用于象动力总成这样的应用。 功率半导体器件 在动力总成应用中，需要开关驱动喷射器、氧气传感器加热器、放气阀、冷却风扇以及一些继电器等负载。在单片IC中集成多个开关可以缩小电路板尺寸，从而降低成本。目前可提供2至18通道的多通道开关器件。根据特定的应用，可驱动从50mA直到30A的电流。负载可以是欧姆负载、容性负载或感性负载。 越来越多的数字逻辑可以在功率输出级一起实现。随着BCD技术的发展，可以在器件中集成许多此前必须由专用ASIC或单片机完成的新功能。 除了这一控制功能外，目前的开关器件还集成了保护和检测功能，如短路、过载、超温、过压、负载开路、静电放电（ESD）和反向电流保护等。此外，还可通过实现在过载时断路以及限流模式等故障保护模式来进一步提高系统可靠性。多通道开关器件通常可利用标准通信接口（SPI）进行控制。诊断信息通过SPI传输回单片机。英飞凌公司还提供了一种高速点到点通信接口，可为未来时间关键的应用（如PWM电流调整）提供更大的数据带宽，并降低微控制器和功率开关器件（如超过 8通道的器件）的I/O端口数量。

Concept car indicates road traffic in the evolution of human behavior Concept foretells the future of the way road traffic trends Along with the development of automobile, the vehicle status is also slowly change, now car in people's minds as a symbol, a symbol of wealth and the embodiment of a status, but the car as a way of the nature of road traffic has overlooked. Concept car design is based on the nature of a car's innovative design predictability. Concept car at the design of the way through the daily life of mankind, human beings in road traffic in the use of methods such as behavior and ways of life all aspects of prediction and analysis, it is envisaged to solve the future in the way road traffic between the object harmonious factors. Strong and high-speed in today's technology enables the development of means of transport have a much broader space for development, more and more high-tech continuously applied at a new car. At present many of the world's major auto companies have realized that the development of the next car is no longer the biggest obstacles are technical limitations, but limits the designers thinking. Now appearing in major auto show concept cars are generally two types: one is based on the latest available technology can achieve another kind of concept cars are those who put forward some innovative technology options but is still in the research phase of the concept car. Able to express their feelings such as car, truck can random shell replacement car, be able to easily change the driving mode of motor vehicles, be able to swim in the water of the amphibious vehicle, able to fly in space vehicles, be able to change cars. Like from Toyota and Sony jointly developed by "POD" cars, will be able to through the car before the lights, mirrors, antenna, as well as the rear seat to the car owners to express their "feelings." Like Volkswagen's Seat International Auto Show in the United States on the introduction of multi-functional concept car "Sal? Juancheng sa", there are sports, comfort and three kinds of urban-type driving mode selection for you. Concept of culture differences in performance The United States as a world leader in the auto industry, concept cars at the manufacturing are on the forefront in the world. At the United States because of cultural blending, collision, so the concept car embodies the greater the diversity of cultures; are also caused by a highly developed country commercial, commercial design and pragmatism prevailed, so the design is set up at a deep aesthetic Ethics on the real and solve practical problems. With the American cars are in sharp contrast to the Japanese concept cars. Japan as the world's output of the second car big country, its concept car many practical and imagination, technology is better than art, more concerned about solving technical problems, it can be said in Japan This is the premise of the concept of car design, each model is to solve one kinds of technical problems developed. The Japanese car model to maintain a small, simple, style characteristics of the economy and harmonious relations between man-machine deal with the Japanese are reflected as a delicate oriental thinking and compromise approach to solve the problem. The United States put the design of commercial operation as an important aspect, Japan put out of Products Designed to accelerate as a tool, Germany put Designed as a social and cultural foundation, while the French took the design as a designer of stage performance. From various countries so the concept of car design in different styles, we can see different countries, different concepts, as well as their different cultural backgrounds design. 3 Concluding remarks The future of automotive design as the development of the inevitable progress of Automotive Technology with each passing day, many of the artistic style of the designer will make it even more widely and more strongly reflected in the car design, and give people a wider choice. Under high-tech, and personality of the car more humane 21st century will be the necessity of the development of the automobile industry, because it is consistent with human culture, the pursuit of individuality and needs.

新能源汽车是指采用非常规的车用燃料作为动力来源（或使用常规的车用燃料、采用新型车载动力装置），综合车辆的动力控制和驱动方面的先进技术，形成的技术原理先进、具有新技术、新结构的汽车。下面是学术堂整理的关于新能源汽车的论文题目，欢迎大家阅读参考：1、对汽车新能源技术的初步探讨2、2011第九届(上海)汽车电子与汽车新能源高峰论坛圆满落幕3、现阶段我国汽车新能源技术发展战略研究4、汽车新能源及润滑油的发展研究5、宝马汽车新能源发展战略6、汽车新能源之氢动力7、21世纪汽车新能源——燃料电池8、汽车新能源领域异军突起的新秀——来自EVS25珠海银通展区的报告9、宝马集团展示汽车新能源技术的现在和未来10、未来的汽车新能源11、汽车新能源的N种可能12、FPT菲亚特动力科技杯中国汽车新能源技术金牌榜揭晓13、汽车新能源开发蕴育绿色革命的到来14、CNG车型走俏 力帆汽车新能源战略将分“两步走”15、也谈汽车新能源——形形色色的清洁汽车“食谱”
具体题目包括：
1、汽车的总体设计(中等难度)。
2、高合器设计(简单)。
3、变速器设计(简单但计算复杂)。
4、液力机械变速器设计(较难度参考资料少)。
5、万向节与传动轴设计(中等难度)。
6、驱动桥设计(简单)。
7、以动桥设计(参考资料少)。
8、悬架设计(中下难度)。
9、转向系设计(简单不包括电动助力)。
10、车架与车身设计(中下难度)。

随着新能源汽车的发展，重本高校来说传统的汽油车类选题其实越来越少了，混动和新能源的课题越来越多，比如，基于比亚迪唐的能量回收系统、基于奇瑞新能源的电池结构设计、基于纯电动汽车的车架总体设计、基于凯美瑞混动的差速器设计等等。
还有一类是难度最高的 simulink matlab cruise ansys仿真，这类的题目也是属于车辆工程的，做的是偏车辆控制，一般研究生才会深入学习，但有些本科院校会要求，比如基于ansys的长安汽车驱动桥设计、基于simulink的四轮转向系统仿真分析、基于matlab的纯电动汽车起步控制策略等等。
