汽车铆钉

有没有去除汽车大梁上铆钉的专用工具?

●用“扁铲”手工就可以把铆钉头打掉,再用冲头冲掉铆钉体。一般钳工用的扁铲就可以,铆工用的扁铲更好。如果量大,可将风镐头部修磨成扁铲状贴着大梁就行,扁铲头部就像一字螺丝刀的头部形状,只不过硬度要相当高才行。

无人驾驶汽车是怎么开的?

●用GPS卫星系统导航
●无人驾驶汽车能灵活自如地自动驾驶汽车,实际上就是模仿人在开汽车,因为它有模仿人“眼”“脑”“脚”功能的装置。
具体来说,在无人驾驶汽车的前方,通常装有两部电子摄像机,这就是它锐利的“眼睛”。

————————
它与人眼不同的是,其两眼是上下排列的,相距50厘米。在汽车行驶时,这两部电子摄像机像人的双眼一样不断地扫描车前方的道路景物,形成实物影像。由此,这两部摄像机就能在前后和上下两个方向上识别阴影的变化,从而准确地分清是阴影还是障碍物。

它的“眼睛”通常能看清前方5~20米范围内的景物。一般是把高度在10厘米以上的物体作为障碍物来处理。这双“眼睛”在扫描过程中,若遇到前方有障碍物,就发出电信号;如果没有障碍物,就不发出电信号。这样,就能及时发现汽车前进方向上的障碍物。当汽车的“眼睛”获得有障碍物的信号后,就及时传送给它的“大脑”微型计算机进行判断,及时决定是继续前进还是停下来,是后退还是绕行?
【这都要求电脑根据实际情况正确处理,并选出最佳的实施方案】
由于人们将预估的各种情况及解决不同问题的最佳方案数据预先输入到电脑中,所以电脑只要相应地从所储存的方案中选择合适的就行了。无人驾驶汽车的“脚”,实际上就是控制汽车行驶的转向器、制动器等,其“脚”是根据电脑下的命令来操控汽车的。

无人驾驶汽车原理是怎样的

●无人驾驶汽车是一种智能汽车,也可以称之为轮式移动机器人,主要依靠车内以计算机系统为主的智能驾驶仪来实现无人驾驶。它一般是利用车载传感器来感知车辆周围环境,并根据感知所获得的道路、车辆位置和障碍物信息,控制车辆的转向和速度,从而使车辆能够安全、可靠地在道路上行驶 无人驾驶汽车集自动控制、体系结构、人工智能、视觉计算等众多技术于一体,是计算机科学、模式识别和智能控制技术高度发展的产物。其中制约无人驾驶汽车量产的原因在与激光雷达的价格以及量产。国外的Velodyne供货周期在8周,国内做的好的速腾聚创供货周期在4周。

乘无人驾驶汽车晕车?

●是不是太紧张造成的。
●无人驾驶的车和普通的车一样的,原本晕车还是晕车,原本不晕还是不晕,区别不大的。
● 在那些鼓吹无人驾驶的人对车里只有乘客的未来期望很高,他们描述未来人类司机可以在无人驾驶的汽车里做其他事情:读书看报、用笔记本工作或者小睡一会什么的。但对于部分人来说,这只是另一个虚无缥缈的未来罢了。根据2014年密歇根大学提供的一项研究报告显示,除去23%的美国人不愿意接受无人驾驶外,剩下的人里有36%虽然愿意把驾驶权交出去给程序,但表示会一直盯着路面。其中一些人盯着车外的原因是这样有助于避免恶心、头晕和呕吐,特别是他们属于那5%-10%的经常晕车的人群的时候。

不过不用担心,解决方法马上就要面世了。上文晕车研究报告的作者们Michael Sivak和Brandon Schoettle都在该大学的交通研究所里就职,他们刚刚取得了一项可以用来对抗晕车的专利。 晕动病是由于机械性地检测运动状态的内耳与以光学的方式检测运动的眼睛传输到大脑的信号冲突引起的,如果乘客在看车内的静止物体如看书,他的眼睛就会告诉大脑说它看到的东西没有动哦。而他的内耳因为检测到车辆在运动,从而与眼睛的信号冲突。起码有一种以上的类似理论解释说,信号的冲突让大脑得出结论说,这个傻X肯定是吃了毒蘑菇之类的导致产生幻觉了,我还是帮他把毒蘑菇吐出来,免得挂掉了,于是大脑发指令给肠胃催吐。 Sivak博士和Schoettle先生的想法是首先在车上安排一系列的小灯光,让乘客无论在车内看什么都会有这些小亮点出现在他们的视野外围。这些灯可能是小型的LED,也可以安装在耳机、帽子或者眼镜框上。这些灯受各种传感器控制,在汽车开起来之后以模仿车辆的速度,滚动,俯仰和其他运动的方式闪烁。 对于用户来说,这些灯光的效果是让视觉信号与内耳检测到的运动信号同步。例如,当车辆向前行驶时,眼睛两侧的灯光可能从前到后闪烁,停车的时候灯光也相对应停下来。同理,当车辆王左右转的时候,也可以用灯光的闪烁速度和亮度模拟车辆的加速度。Sivak博士和Schoettle先生的专利里,灯光阵列还可以布置在车辆内的各个位置,例如车门支柱,侧壁和座椅上。这样一来乘客就不需要佩戴专门的设备就可以感知灯光。 密歇根大学的团队正在制造这个专利的原型机并希望能商业化,为此大学正在与汽车制造商及供应商进行讨论。当然,这个系统可以安装在有人驾驶汽车上面,特别是儿童特别容易晕车,虽然儿童比成人坐车敏感的原因至今不明。尽管飞机和船只的移动方式和汽车大相径庭,但这套系统也可能助于解决晕机晕船等其他形式的晕动病。对于大众来说,这套系统可以让自己有一次舒适的乘车体验就够了。而对于像优步和Lyft这种计划在未来提供无人驾驶出租车服务的公司来说,这些闪闪的小灯可以省下一大笔清洁费。

中国的汽车产业英文介绍

问题补充:中国的汽车产业英文介绍
●A bus is a large road vehicle intended to carry numerous persons in addition to the driver and sometimes a conductor. The name is a shortened version of Latin omnibus, which means "for everyone."HistoryThe omnibus, the first organized public transit system, may have originated in Nantes, France in 1826, when Stanislas Baudry, a retired army officer who had built public baths (run from the surplus heat from his flour mill) on the city's edge, set up a short stage line between the center of town and his baths. The service started on the Place du Commerce, outside the hat shop of M. Omnès, who displayed the motto Omnès Omnibus ("Omnès for all") on his shopfront. When Baudry discovered that passengers were just as interested in getting off at intermediate points as in patronizing his baths, he shifted the stage line's focus. His new voiture omnibus ("carriage for all") combined the functions of the hired hackney carriage with the stagecoach that travelled a predetermined route from inn to inn, carrying passengers and mail. His omnibus featured wooden benches that ran down the sides of the vehicle; entry was from the rear.There is also a claim from the UK where in 1824 John Greenwood operated the first "bus route" from Market Street in Manchester to Pendleton in Salford.[citation needed]Whether by direct emulation, or because the idea was in the air, by 1832 the idea had been copied in Paris, Bordeaux and Lyons. A London newspaper reported in July 4, 1829 that "the new vehicle, called the omnibus, commenced running this morning from Paddington to the City". This bus service was operated by George Shillibeer. "Omnibus," crayon and watercolor drawing by Honoré Daumier, 1864 (Walters Art Museum).In New York, omnibus service began in the same year, when Abraham Brower, an entrepreneur who had organized volunteer fire companies, established a route along Broadway starting at Bowling Green. Other American cities soon followed suit: Philadelphia in 1831, Boston in 1835 and Baltimore in 1844. In most cases, the city governments granted a private company—generally a small stableman already in the livery or freight-hauling business—an exclusive franchise to operate public coaches along a specified route. In return, the company agreed to maintain certain minimum levels of service—though one of these standards was not upholstery. The New York omnibus quickly moved into the urban consciousness. In 1831, New Yorker Washington Irving remarked of Britain's Reform Act (finally passed in 1832): "The great reform omnibus moves but slowly."The omnibus had many repercussions for society, particularly in that it encouraged urbanization. Socially, the omnibus put city-dwellers, even if for only half an hour, into previously-unheard-of physical intimacy with strangers, squeezing them together knee-to-knee (illustration, left). Only the very poor remained excluded. A new division in urban society now came to the fore, dividing those who kept carriages from those who did not. The idea of the "carriage trade", the folk who never set foot in the streets, who had goods brought out from the shops for their appraisal, has its origins in the omnibus crush.The omnibus also extended the reach of the North Atlantic post-Georgian, post-Federal city. The walk from the former village of Paddington to the business heart of London in the "City" was a brisk one for a young man in good condition. The omnibus offered the nearer suburbs more access to the inner city.More intense urbanization was to follow. Within a very few years, the New York omnibus had a rival in the streetcar: the first streetcar ran along The Bowery, which offered the excellent improvement in amenity of riding on smooth iron rails rather than clattering over granite setts, called "Belgian blocks". The new streetcars were financed by John Mason, a wealthy banker, and built by an Irish contractor, John Stephenson. The streetcars would become even more centrally important than the omnibus in the future of urbanization. The world's first motorized bus - a Benz truck modified by the Netphener Omnibusgesellschaft in Netphen, Germany (1895)When motorized transport proved successful after c. 1905, a motorized omnibus was for a time sometimes called an autobus.Buses began to replace streetcars in the U.S. because of a continuing series of technical improvements: pneumatic "balloon" tires during the early 1920s, monocoque body construction in 1931, automatic transmission in 1936, the diesel-engine bus in 1936, the first acceptable 50+ passenger bus in 1948, and the first buses with air suspension in 1953. [1]Bus services were a focal point in the American Civil Rights Movement of the 1950s and 1960s in the United States. In the period after the American Civil War ended in 1865, racial segregation in public accommodations, including public transport such as rail and bus services, was enforced through Black Codes and Jim Crow laws. These were made to prevent African-Americans from doing things that a white person could do. For instance, Jim Crow laws required bus drivers to enforce separate seating sections. These laws and enforcement varied among communities and states. In 1955, after a long day of work, Rosa Parks, a black seamstress, was arrested in Montgomery, Alabama for refusing to give up her seat to a white man on a public bus, bringing attention to the injustice of differential and degrading treatment based solely upon race. This incident, boycotts of bus services, other protests, and court challenges led a U.S. Supreme Court ruling banning segregation on public buses and helped lead the U.S. Congress to pass the landmark 1964 Civil Rights Act which clarified the unconstitutionality of public racial segregation laws. Mexican BusIn some areas of the United States, a forced busing system has been used to achieve racial desegregation of public schools. Under such a busing plan, children do not necessarily go to the nearest school geographically, but to such a public school in the same district where there is an appropriate mix of racial diversity.Types of bus service A typical bus-stop in Singapore.Buses are an intrinsic part of everyday life, and play an important part in the social fabric of many countries. Many urban public transportation systems rely on bus services. The largest single city bus fleet in North America is in New York City.Bus services can fit into several broad classes. Local transit buses provide public transit within a city or one or more counties, usually for trips of only a few Kilometers or tens of km. Intercity, interstate or interprovincial buses provide transit between cities, towns, rural areas and places usually tens or hundreds of kilometers away. They generally provide fewer bus stops than local bus routes do. Greyhound Bus Lines and Trailways Transportation System are examples of US interstate bus systems. Some local transit systems offer bus lines to nearby cities or towns served by another transit agency. Intercity bus services have become an important travel connection to smaller towns and rural areas that do not have airports or train service.Some public transit bus systems offer express bus service in addition to local bus lines. Local lines provide frequent stops along a route, sometimes two or more per Kilometer, while express lines make fewer stops and more speed along that route. For example, an express bus line may provide speedier service between a local airport and the downtown area of a nearby city.Shuttle bus service provide transit service between two destinations, such as an airport and city center. Shuttle bus services are often provided by colleges, airports, shopping areas, companies, and amusement destinations.Tour bus service shows tourists notable sights by bus. City tour buses often simply pass by the sites while a tour guide describes them. Longer distance tour coaches generally allow passengers to disembark at specific points of interest. Some tourist buses are decorated to resemble pre-PCC streetcars in order to attract tourists or for other appearance purposes. A similar phenomenon is Duck Tours, which uses amphibious DUKWs converted into buses/cruise boats for tour purposes.School bus service provides transit to and from school for students. Some private schools use school buses only for field trips or sports events. Some school systems, such as the San Francisco public school system, do not operate their own school bus system but instead rely on the local public transit bus system to provide transportation for the system.Charter bus operators, provide buses with properly licensed bus drivers for hire
