Automobile lamps adaptive development and reviewed in this paper

With the development of the society and the continuous improvement of people's living standard, people on the requirements of the car has not only confined to performance, cost, but more and more requirements modern car safer, more environmental protection and more human. Car manufacturers are using more security, more environmental protection, design is more elegant and more province oil advantages to attract users. And at the same time, the new car should also must comply with the latest regulation, this has led to a new technology to get the application. As the big three auto safety thing, automobile lighting systems is one of the main active safety device, to the traditional automobile lighting system improvement and innovation also has become a hot spot in the study of the world automobile manufacturers.

Therefore, how to make automotive lighting, driving more intelligent safety, more comfortable will become a very urgent and has the important practical significance of the subject. The traditional automobile lighting system mainly by the headlamps system, lighting system, signal car lighting system composed of three. With the progress of science and technology, traditional lighting system also experienced rapid progress, the corresponding traffic regulations also more and more perfect, headlamps system has gone through a kerosene lamp from the original to incandescent lamp, halogen lamp to now discharge lamp of the development process, the signal from the first portable lighting system development now widely applied to a kerosene lamp LED lights, the car lighting system is more and more kinds, more and more humane. But the actual use of traditional headlamps system, there are many problems. For example, the existing in the light of the close on lighting effect is very bad, especially in the urban traffic is more complex, often have a lot of drivers in the evening nearly light, and front fog lamps entirely open headlights; Vehicles in turning the corner, there are also lighting dark areas, the serious influence the driver on the

corners on the judgment of the obstacles; Vehicles driving on a rainy day, the ground water reflected the headlights, produce light reflected glare, and so on. According to statistics, about 50% of the night accident happened without lighting facilities of the dark road, road lighting the poor, the greater the likelihood of accident. The night accounted for 33.1% of the total number of accidents accident (although driving at night accounts for only 1/5 of the rate during the day). The death toll is about 50%, compared to 12.4% during the day, the death rate from the accident, and the night for 33, 7%. The night and high death rate from multiple accident, and the reason is the eyesight of the driver and the lower than about 1/2. In addition the rain and fog will also make vision loss, glass and dirty water before not only reduced vision, still can make the distance distortion, which must be the attention of the driver. European car lighting research institutions in the once a special investigation, the results showed that the most wants to improve the European drivers of the wet weather is the lighting of the water came in second, a rural road lighting, the next is in turn corners lighting, highway lighting and urban lighting. The above of these problems, make developing a DuoZhong lighting function with the lighting system become necessary, and the function of switching, for security reasons, and must be automatically, thus, adaptive lighting system (ALS) will emerge as The Times require.

At present, our country of all motor vehicle testing lines are equipped with headlamps inspection instrument, many experts and scholars are many important is also discussed in the paper. But, through the test of a station exploits the year two thousand Taiwan client survey analysis, vehicle headlamps a total qualified by only 45%, and these qualified vehicles and most of all foreign imports of the vehicle. Is Cause the situation are the main reasons: (1) the car factory products do not meet the national standards, and many of the car factory in just when examination is not qualified, headlamps But others just a factory qualified, but can't use how long and then aging, poor durability. (2) the most vehicles have the lack of units and the unit testing conditions and means, in the headlamps for maintenance, adjust the inaccurate even will not be adjusted. (3) because some leadership and drivers are subjective

safety, think in car headlamp is not safety testing is very important, as long as the car brake performance that can assure safety, so for lack of maintenance and maintenance, headlamps on schedule maintenance and replacement cannot. (4) for most of the testing station can't test results in a timely and accurate to inform owners in testing station, in the practice of the factory also cannot fundamentally solve the problem. Make a complete year after year while still driving. This is CheJian departments and testing station should be improved and self perfection in. Automobile lamps when regular testing unqualified has the following three conditions: (1) the luminous intensity enough; (2) the bad light distribution, main beam axis skewed a quantity to exceed bid; (3) above two kinds of circumstances exist. The influence factors of its own problems have vehicles, such as: battery electric power system can't deficit or charging, test power system should be in charge state; Wire corrosion; Tire pressure is insufficient; Tire model about different; Adjustment screws to adjust the improper; Glass chimney on the dirt and headlamps quality problem. Also have a plenty of testing lines light inspection instrument installation accuracy and precision is unqualified, such as: light meter guide levelness enough; Lines of the ground does not level off; When parking lights and the level of the instrument headlamp distance is not accurate; The longitudinal axis and inspection instrument vehicle guide not vertical; Instrument range is not accurate. These are caused by the unqualified headlamp factors, among which light inspection instrument because every year by special inspection agency calibration and qualified rear can use, therefore, the vehicle itself problem is the main reason. Vehicles unit, drivers and keep the repair personnel should be paid much attention to. Automobile lamps adaptive system to, corner sensor, abundant between front axle, control unit altitude sensor (ECU), and stepper motor of headlights. The basic principle is: when the automobile longitudinal swing, ECU acquisition sensor signal, through the internal control strategy, control the stepping motor rotation, thus promote headlamps turned the corresponding point of view, the main design to car longitudinal swing automobile lamps automatic adjust the Angle made drivers can have greater vision, reduce the driver's blind area, and avoiding risk, improve the security and stability of the car, this is very important.

With more and more bright lights at night at the same time, improve visibility, how to avoid strong light onto the driveway, and to cause to car drivers of smooth shadow produces visual residual, losing the ability to identify and road conditions should be a body in a dangerous situation, so can effective improve the scope of the automotive lighting and Angle, is improve the night driving safety important issue. In addition to the steering wheel steering Angle according to the head lamp or so direction adjustment, reduce the parameters of the night vision blind Angle, but also must pay attention to the fluctuation level, because body vulnerable to load average or not is the way, ups and downs changes, resulting in body produce Angle, joint influence round the point of view of the project lamp. Pledge lamp too high, easy to make projection Angle to car drivers have dazzle light problem, when cast Angle is too low, the line of sight of driving itself could be a deficiency, or less than myself or others will be exposed to danger, so level (elevation Angle) control is necessary to maintain the stability of the lighting Angle. The head lamp level control from the early passive manual adjustment, half active into the present automatic type, half is active in a car the adjustment, automatic type is braking can also do real-time adjustments. Level automatically adjust the system based on the foundation of the original setting Angle, through the height difference sensors detect body under circumstances, calculate the light cast Angle offset, upwards or to adjust HID DengZu, maintain proper illuminate Angle. Advanced level automatically adjust the Angle projection system, will also make adjustment screw with speed. A high speed will further, in beam to real time see the greater distance road conditions, slow speed, lighting Angle to correction, avoid exposure to the driveway. Intelligent lamp is the lamp of the technology another development the mainstream. Adaptive headlights integrated operation speed, steering Angle and the degree of body forward has happened to adjust the parameters as the direction of the light source, so according to strictly can only be regarded as passively accept driver needs to adjust the lighting Angle, and active steering head lamp still had some differences. Released in 2008 and is expected to active the head lamp system, to receive more information to determine the appropriate again after the head lamp brightness and Angle projection, to the

so-called active safety state. In addition to the existing wheel shaft height difference sensors, steering sensors,, the electronic control unit can order early to drive system, adjust the lighting Angle and light type.

汽车前照灯自适应发展综述

随着社会的发展和人们生活水平的不断提高，人们对汽车的要求已不仅仅局限于性能，成本，而是越来越多的要求现代汽车更加安全，更加环保，更加人性化。汽车生产商们也正在用更安全、更环保、设计更精美以及更省油料等优点来吸引用户。而同时，新车款型也必须符合最新的规定，这就导致了新技术不断得到应用。作为汽车的三大安全件之一，汽车照明系统是最主要的主动式安全装置，对传统汽车照明系统的改进和创新也日益成为全世界汽车厂商研究的热点问题。

因此，如何使汽车照明智能化，驾车更安全，更舒适就成为一个十分紧迫而又有重大现实意义的课题。传统的汽车照明系统主要由前照灯系统，信号照明系统，车内照明系统三大部分组成。随着科技的进步，传统照明系统也经历了长足的发展，相应的交通法规也越来越健全，前照灯系统就经历了从最初的煤油灯到白炽灯，卤素灯到现在的气体放电灯的发展过程，信号照明系统从最初的手提煤油灯发展到现在普遍应用的LED信号灯，车内照明系统更是种类越来越多，越来越人性化。但是实际的使用中，传统的前照灯系统存在着诸多问题。例如，现有近光灯在近距离上的照明效果很不好，特别是在交通状况比较复杂的市区，经常会有很多司机在晚上将近光灯、远光灯和前雾灯统统打开；车辆在转弯的时候也存在照明的暗区，严重影响了司机对弯道上障碍的判断；车辆在雨天行驶的时候，地面积水反射前灯的光线，产生反射眩光等等。据统计，夜间事故中约有50％发生在没有照明设施的黑暗道路上，道路照明越差，事故发生的可能性就越大。夜间事故占事故总数的33．1％(虽然夜间出车率只占白天的1／5)。死亡人数则为50％左右，对比致死率，白天事故为12．4％，而夜间为33、7％。夜间事故多发和高的致死率，其原因就是驾驶员的视力与白天相比约降低1／2。此外雨和雾也会使视力下降，前窗玻璃脏得和水滴不仅使视力降低，还会使距离感失真，必须引起驾驶员的注意。欧洲汽车照明研究机构曾经就此作过专项调查，结果显示，欧洲司机们最希望改善的是阴雨天气积水路面的照明，排在第二位的是乡村公路的照明，接下来依次是弯道照明、高速公路照明和市区照明。上述这些问题的存在，就使得研制一种具有多种照明功能的照明系统成为必要，并且这些功能的切换，出于安全上的考虑，必须是自动实现的，由此，自适应照明系统(ALS)也就应运而生了。

目前，我国所有的机动车检测线都装有前照灯检验仪，许多专家学者对此也做过许多重要的论述。但是，通过对哈市检测一站的本年度二千台受检车辆进行

调查分析，前照灯一检总的合格仅为45％，而这些合格的车辆当中大多数又都是外国进口的车辆。造成这种局面的主要原因有：①汽车制造厂的产品不符合国标标准，有许多刚刚出厂的汽车在检验时前照灯就是不合格的；也有的是刚出厂时合格，但用不了多久就老化，耐久性差。②大多数车辆保有单位和调修单位缺乏检验条件和手段，在对前照灯进行保养时，调整不准确甚至不予调整。③由于一些领导和驾驶员缺乏主观安全性，认为前照灯在汽车安全检测中并不是非常重要的，只要汽车的制动性能好就可保证行车安全，因而对前照灯缺乏维护和保养，不能按期检修和更换。④对于大多数检测站不能把检测结果及时准确地通知车主，在检测站内设置的调修厂也不能从根本上解决问题。使得在用车辆年复一年仍然带病行驶。这是车检部门和检测站应该改进和自我完善之处。汽车前照灯定期检验时不合格有如下三种情况：①发光强度不够；②配光不好，主光轴偏斜量超标；③以上两种情况同时存在。其影响因素有车辆自身的问题，比如：电瓶亏电或电源系统不能充电，测试时电源系统应处于充电状态；导线锈蚀；轮胎气压不足；左右轮胎型号不同；调整螺钉调整得不当；玻璃灯罩上有污物以及前照灯质量问题等。也有的是检测线的灯光检验仪安装精度和检测精度不合格，比如：灯光仪导轨水平度不够；检测线地面不平整；停车时前照灯与灯光仪的水平距离不准确；车辆纵轴线与检验仪导轨不垂直；仪表量程不准确等。这些都是造成前照灯不合格的因素，其中由于灯光检验仪每年都要由专门检验机构进行标定，合格后方可使用，因而，车辆自身问题是最主要原因。车辆保有单位、驾驶员和调修人员对此应十分注意。汽车前照灯自适应系统丰要，转角传感器，前后轴高度传感器，控制单元(ECU)，步进电机及前灯组成。其基本工作原理是：当汽车纵向摆动时，ECU采集传感器信号，通过内部控制策略，控制步进电机转动，从而带动前照灯转过相应角度，此次设计主要偏向汽车纵向摆动时汽车前照灯自动调整角度使驾驶员能有更大的视野，减小驾驶员的盲区，避免发生危险，提高汽车的安全性和稳定性，这是非常重要的。

随着车灯愈来愈亮，提升夜间能见度的同时，如何避免强光投射到对向车道，造成来车驾驶者产生视觉的光影残留，失去对路况应有的辨识能力而身处于险境，所以能有效的改善汽车照明的范围与角度，才是提高夜间行车安全的重要课题。除了依据方向盘的转向角去作头灯的左右方向调整，减少夜间行车的视觉死角之外，还需注意到上下水平，因为车体容易受到载重不平均或者是道路起伏变化，造成车身产生倾斜角度，连带影响到头灯所投射的角度。当头灯投射角度过高，容易使来车驾驶人产生炫光问题，当投射角度过低，本身驾驶的视线则会不足，过或者不及都会将自己或他人暴露于危险，所以水平(俯仰角)控制是必需的，

以维持照明角度的稳定。头灯水平控制从早期的被动式手动调整、半主动式到目前的自动式，半主动式是在汽车发动时调整一次，自动式则是做到刹车时也能做实时调整。自动水平调整系统依据原厂设定的基础角度，透过轮轴高度差传感器侦测车身的荷重情形，计算出光线投射角度的偏移量，往上或往下调整HID灯组，维持适当的照射角度。进阶的自动水平调整系统，投射角度还会随着车速的快慢做调整。高速行驶时，将光束照得较远，以便实时看清较远距离的路况，慢速行驶时，灯光角度往下修正，避免照射对向车道。智能车灯是当前车灯技术的另一个发展主流。适应性头灯综合运算车速、方向盘转向角度、车身侧倾程度等已发生的参数来做为调整灯源方向的依据，因此严格来说只能算是被动地接受驾驶者需求来调整照明角度，与主动式转向头灯仍有些许差异。预计于2008年推出的主动式转向头灯系统，接收更多信息之后再来判断适当的头灯投射亮度与角度，达到所谓的主动安全的境界。除了既有的轮轴高度差传感器、方向盘转向传感器、，电子控制单元可提早下命令至传动机构，调整灯光角度与光型。

01-文献综述范文-翻译-当前零翻译研究问题与对策

外国语学院2018届毕业论文文献综述（示范） 一、研究背景 近来多篇论文中出现零翻译的提法（杜争鸣，2000；邱懋如，2001；刘明东，2002；袁斌业，2002a，2002b，2002c，2002d；石琳，2003；余清萍，2003；余清萍，秦傲松，2004；肖耀田，2004），但国内学者所编三本译学词典（林煌天，1997；孙迎春，1999；方梦之，2004）均未出现零翻译这一词条，国外三本词典/术语著作（Shuttleworth & Cowie，1997；Baker，1998；Delisle，2004）亦未收入这一条目，只有国内孙迎春（2001）编著的《汉英双向翻译学语林》收进了“零翻译（音译、形译之一种）zero translation”（58页）及“zero translation零翻译（音译、形译之一种）”（268页）两个条目，同时又有贾影（2002）反对零翻译提法，并认为承认不可译有“积极作用”。但零翻译现象确实存在，如DIY（自己动手），IQ（智商），EQ（情商），这些零翻译词汇经常在汉语中出现。英语中也有类似情况，如美国《时代》周刊中报道中国特色事物时经常使用拼音，如aizi(矮子)，pizi（痞子），shiganjia（实干家），yuan（缘）（王祥兵，2002），shuangying(双赢)，guanxi(关系)（顾静，2005）。 这些研究成果揭示了零翻译现象的存在，引进了零翻译的概念，促进了翻译理论概念的扩大，但是从发表的论文及孙迎春（2001）的这两个条目来看，各自运用的名称虽同（也有不同，如杜争鸣称为不译），但概念的内涵及外延均有出入，因此有必要探讨当前零翻译研究的问题并提出相应研究对策。 二、研究现状及不足 1. 定义不统一、模糊不清 传统翻译理论多把零翻译归结为“音译法”、“移译法”，只看到技巧层面的意义，如秦建栋（1999）讨论“英汉词汇空缺现象刍议”列举“音译法”、“移译法”，袁斌业（2001）论及“英语本族人音译汉语词汇的语用分析”，虽然看到“音译在我国只能用来翻译名词，而在国外则可以用来翻译包括名词在内的各种词语”，但未能从中提炼出零翻译的概念，实际上这里已包含有零翻译与音译的某些区别。 国内最早使用zero translation这一术语的是杜争鸣（2000），但他称之为“不译”，并分析了直译、意译与不译三种翻译策略。他不停留于策略本身，从跨文化交际的视角分析了三种策略的社会语言学与跨文化交际涵义，并看到了不译的三层文化含义。不译背后体现译者对于翻译目的的认识，“而翻译的目的必然直接或间接地反映反映译者本人对翻译的文化含义的意识与潜意识，反映他翻译时所采取的文化姿态与立场。”即翻译观的问题。但从术语的精确性来说

The Competitive Dynamics in the Automotive Aftermarket: Branded Products and Private Label Products THE BUSINESS CASE Throughout the automotive aftermarket industry,senior executives are facing the reality of private brands. Similar dynamics exist outside of the automotive aftermarket and are intensifying in other sectors, such as traditional consumer goods. Also known as ―private label‖ and referred to across many consumer-oriented industries as ―store brands,‖ ―control brands‖ or ―own brands,‖ their risin g prominence has led top executives to ask: ? What issues and risks do U.S.-branded manufacturers face with respect to private brands? ? How are market forces different today than in years past? How will this landscape evolve? ? How can I better understand my operational blind spots in an increasingly competitive landscape? ? What can my management team focus on to protect and grow my brands? Where do we start? ?What are the similarities and differences between the private brand trends in the automotive aftermarket and the consumer products sector? ? What can be learned by automotive aftermarket executives from the private brand experiences in other sectors? Although answers to these questions are not simple and some market dynamics are not yet fully clear, the availability of private brands and other competitive trends are growing in the automotive aftermarket community, just as they are in many consumer product segments. One out of every three consumer products sold by one of the nation’s largest retailers is now private brand – up from one out of every five just a few years ago. With U.S. private brand sales in the grocery market surpassing well over $80 billion, for example, private brands can no longer be ignored by consumer product manufacturers. The U.S. market share of private brands in food, drug and mass merchant channels is more than 20 percent, according to industry data research firms. More than 80 percent of consumers shopping in big box, warehouse clubs and superstores frequently buy store brands and, depending on the specific product category, multiple store brands at a time. Retailers are focusing more resources on private branding to enhance margins, increase shelf velocity and expand store

摘要 将稳定控制系统应用于差动制动内/外轮胎是现在对客车车辆的标准（电子稳定系统ESP、直接偏航力矩控制DYC）。这些系统假设将两个偏航率(通常是衡量板)和侧滑角作为控制变量。不幸的是后者的具体数值只有通过非常昂贵却不适合用于普通车辆的设备才可以实现直接被测量,因此只能估计其数值。几个州的观察家最终将适应参数的参考车辆模型作为开发的目的。然而侧滑角的估计还是一个悬而未决的问题。为了避免有关参考模型参数识别/适应的问题,本文提出了分层神经网络方法估算侧滑角。横向加速度、偏航角速率、速度和引导角,都可以作为普通传感器的输入值。人脑中的神经网络的设计和定义的策略构成训练集通过数值模拟与七分布式光纤传感器的车辆模型都已经获得了。在各种路面上神经网络性能和稳定已经通过处理实验数据获得和相应的车辆和提到几个处理演习(一步引导、电源、双车道变化等)得以证实。结果通常显示估计和测量的侧滑角之间有良好的一致性。 1 介绍 稳定控制系统可以防止车辆的旋转和漂移。实际上，在轮胎和道路之间的物理极限的附着力下驾驶汽车是一个极其困难的任务。通常大部分司机不能处理这种情况和失去控制的车辆。最近,为了提高车辆安全，稳定控制系统(ESP[1,2]; DYC[3,4])介绍了通过将差动制动/驱动扭矩应用到内/外轮胎来试图控制偏航力矩的方法。 横摆力矩控制系统（DYC）是基于偏航角速率反馈进行控制的。在这种情况下,控制系统使车辆处于由司机转向输入和车辆速度控制的期望的偏航率[3,4]。然而为了确保稳定，防止特别是在低摩擦路面上的车辆侧滑角变得太大是必要的[1,2]。事实上由于非线性回旋力和轮胎滑移角之间的关系，转向角的变化几乎不改变偏航力矩。因此两个偏航率和侧滑角的实现需要一个有效的稳定控制系统[1,2]。不幸的是,能直接测量的侧滑角只能用特殊设备(光学传感器或GPS惯性传感器的组合)，现在这种设备非常昂贵,不适合在普通汽车上实现。因此, 必须在实时测量的基础上进行侧滑角估计，具体是测量横向/纵向加速度、角速度、引导角度和车轮角速度来估计车辆速度。 在主要是基于状态观测器/卡尔曼滤波器(5、6)的文学资料里, 提出了几个侧滑角估计策略。因为国家观察员都基于一个参考车辆模型,他们只有准确已知模型参数的情况下，才可以提供一个令人满意的估计。根据这种观点,轮胎特性尤其关键取决于附着条件、温度、磨损等特点。 轮胎转弯刚度的提出就是为了克服这些困难,适应观察员能够提供一个同步估计的侧滑角和附着条件[7,8]。这种方法的弊端是一个更复杂的布局的估计量导致需要很高的计算工作量。 另一种方法可由代表神经网络由于其承受能力模型非线性系统，这样不需要一个参

In particular, with the rise and rapid de velopment of independent brand’s vehicles, we pay more attention To the development processes and the technical requirements of hard Points’ layout. Through the three typical processes such as modern vehicle developing Process, body development process and using ergonomic to progress Inner auto-body layout, describe ergonomic layoationship between design, Aunt design in which stage of the process of vehicle development, the red The importance of working steps. The automobile body total arrangement is the automobile design most initial is also the most essential step, is other design stage premise and the foundation, to a great extent is deciding the body design success or failure. Picks generally in the actual design process With by forward and reverse two design method (1) to design (from inside to outside law) to design method namely "humanist", is coming based on the human body arrangement tool to define the pilot and the crew member gradually rides the space and the vehicle comes to pay tribute each article the arrangement, take satisfies the human body to ride with the driving comfortableness as the premise, said simply is determined first satisfies the human body to ride under the comfortable premise, carries on the indoor arrangement first, then carries on the complete bikes external styling design again. The concrete method and the step are as follows: ①Determine 5% and 95% manikin H position and the chair by the SAE recommendation's enjoyable line or the region law adjustment traveling schedule, seat

附录 图像科学综述 近几年来，图像处理与识别技术得到了迅速的发展，现在人们己充分认识到图像处理和识别技术是认识世界、改造世界的重要手段。目前它己应用于许多领域，成为2l世纪信息时代的一门重要的高新科学技术。 1.图像处理与识别技术概述 图像就是用各种观测系统以不同形式和手段观测客观世界而获得的，可以直接或间接作用于人眼而产生视知觉的实体。科学研究和统计表明，人类从外界获得的信息约有75%来自于视觉系统，也就是说，人类的大部分信息都是从图像中获得的。 图像处理是人类视觉延伸的重要手段，可以便人们看到任意波长上所测得的图像。例如，借助伽马相机、x光机，人们可以看到红外和超声图像：借助CT可看到物体内部的断层图像；借助相应工具可看到立体图像和剖视图像。1964年，美国在太空探索中拍回了大量月球照片，但是由于种种环境因素的影响，这些照片是非常不清晰的，为此，美国喷射推进实验室(JPL)使用计算机对图像进行处理，使照片中的重要信息得以清晰再现。这是这门技术发展的重要里程碑。此后，图像处理技术在空间研究方面得到广泛的应用。 总体来说，图像处理技术的发展大致经历了初创期、发展期、普及期和实用化期4个阶段。初创期开始于20世纪60年代，当时的图像采用像素型光栅进行扫描显示，大多采用巾、大型机对其进行处理。在这一时期，由于图像存储成本高，处理设备造价高，因而其应用面很窄。20世纪70年代进入了发展期，开始大量采用中、小型机进行处理，图像处理也逐渐改用光栅扫描显示方式，特别是出现了CT和卫星遥感图像，对图像处理技术的发展起到了很好的促进作用。到了20世纪80年代，图像处理技术进入普及期，此时购微机已经能够担当起图形图像处理的任务。VLSL的出现更使得处理速度大大提高，其造价也进一步降低，极大地促进了图形图像系统的普及和应用。20世纪90年代是图像技术的实用化时期，图像处理的信息量巨大，对处理速度的要求极高。 21世纪的图像技术要向高质量化方面发展，主要体现在以下几点：①高分辨率、高速度，图像处理技术发展的最终目标是要实现图像的实时处理，这在移动

Dashboard From Wikipedia, the free encyclopedia This article is about a control panel placed in the front of the car. For other uses, see Dashboard (disambiguation). The dashboard of a Bentley Continental GTC car A dashboard (also called dash, instrument panel (IP), or fascia) is a control panel located directly ahead of a vehicle's driver, displaying instrumentation and controls for the vehicle's operation. Contents 1.Etymology 2.Dashboard features 3.Padding and safety 4.Fashion in instrumentation 5.See also 6.References Etymology Horse-drawn carriage dashboard Originally, the word dashboard applied to a barrier of wood or leather fixed at the front of a horse-drawn carriage or sleigh to protect the driver from mud or other debris "dashed up" (thrown up) by the horses' hooves.[1] Commonly these boards did not perform any additional function other than providing a convenient handhold for ascending into the driver's seat, or a small clip with which to secure the reins when not in use. When the first "horseless carriages" were constructed in the late 19th century, with engines mounted beneath the driver such as the Daimler Stahlradwagen, the simple dashboard was retained to protect occupants from debris thrown up by the cars' front wheels. However, as car design evolved to position the motor in front of the driver, the dashboard became a panel that protected vehicle occupants from the heat and oil of the engine. With gradually increasing mechanical complexity, this panel formed a convenient location for the placement of gauges and minor controls, and from this evolved the modern instrument panel,
