Self-drivingcars—destinationknown?自动驾驶汽车----目的地

目的地格兰酒店。家庭模式。出发。”汽车立即响应，平稳驶入繁忙的车流，避开路上的障碍。车里面，一家人已经在弹出式显示面板上选好了娱乐项目，为前方的旅途作好准备。这个想象中的场景展示了自动驾驶汽车，也叫自主汽车，一种可能的未来的现实。However,beforethisevolutionintransportbecomesarevolution,itmustbefullyunderstoodhowself-drivingcarswork.Putsimply,self-drivingcarsmust"see"and"behave"appropriatelytobesafeontheroad.Theydothisthroughvarioushardwareanddeep-learningAI.Camerasaswellassensorslikeradarandlidarcaptureavarietyofdatafromtheexternalenvironment.OncethedataissenttotheAIsystem,the"brain"ofthecar,itisanalysedandputtogetherlikeapuzzlesothattheself-drivingcarcan"see"itssurroundingsanddetermineitsposition.Meanwhile,theAlsystemidentifiespatternsfromthedataandlearnsfromthem.Anactionplanisthencreatedtoinstructthecarhowto"behave"inrealtime:stayinthelane,moveintoanotherone,speeduporslowdown.Next,thenecessarymechanicalcontrols,suchastheacceleratorandbrakes,areactivatedbytheAIsystem,allowingthecartomoveinlinewiththeactionplan.然而，在这种交通方式的变革成为一场革命之前，必须充分了解自动驾驶汽车的工作原理。简言之，要想在路上安全行驶，自动驾驶汽车必须恰当地“看”和“做”。它们通过各种硬件和深度学习人工智能(AI)

来实现。摄像头以及雷达、激光雷达等传感器从外部环境中获取各种数据。数据一日发送到人工智能系统，即自动驾驶汽车的“大脑”，立即被分析并像拼图一样被拼凑起来，于是汽车就能“看到”周围的环境并确定自身方位。同时，人工智能系统从数据中识别出模式，从中学习。然后一份行动计划被创建出来，用以指导汽车如何实时“行动”:沿车道行进，变道，加速或减速。接下来，人工智能系统激活油门、刹车等必要的机械操纵装置，让汽车按照行动计划行驶。Thismaysoundperfectintheory,butinrealitytechnologicalbarriersinAVdevelopmentexist.Theself-drivingcar'sperceptionsystempresentsone.Roadtrafficintherealworldissocomplicatedthatunfamiliarorunexpectedconditionsmayoccuratanytime.Sinceitisunreasonableforthedatabasetoincludeeverypossibleobjectineverypossibleconditionaheadoftime,thesystemmightnotrecognizeeverythingontheroad.Inonetragicreal-lifecase,aself-drivingcar'sperceptionsystemfailedtoidentifyawhitetruckagainstthebright,sunlitsky.Itassumedthattherewasnoobstacleinitspathanddidnotactivatethebrakes,causingthedeathofthedriverintheself-drivingcar.Accidentslikethisposethequestionofhowself-drivingcarscanbetterlearnandimprovetheirbehavioursontheroadtoensuresafejourneys.这理论上听起来很完美，但实际上，自动驾驶汽车的开发还存在技术障碍。其感知系统就是一个例子。真实世界中的道路交通如此复杂，以至于不熟悉或意外的情况时有发生。既然数据库将每种可能发生的情况下的每个可能存在的物体都预先包含是不合理的，系统就无法识别路上所有东西。在一个悲惨的真实案例中，一辆自动驾驶汽车的感知系统未能从明亮晴空的背景下识别一辆白色卡车。它只当行进路线上没有障碍物，没刹车，导致自动驾驶汽车的司机死亡。此类事故提出了这样一个问题，即自动驾驶汽车怎样才能更好地学习，改进行驶中的行为以确保安全出行。Anotheraspectthatneedscarefulconsiderationistheethicalresponsesself-drivingcarswouldmakeinspecificcircumstances.TheTrolleyProblemisoftenusedtodiscussdifficultethicalchoicestheymayface.Forexample,shouldthoseintheself-drivingcaralwaysbeprotectedfirstevenifitmeansendangeringthelivesofpedestrians?Shouldaself-drivingcarhitasinglepedestriantoavoidcrashingintoagroupofpedestrians?Andwoulditmakeadifferentdecisionifthepedestrianwereachildoraseniorcitizen?Themoraldilemmathatcomeswithhowtoethicallyprogramself-drivingcarshasyettoberesolved.另一个需要仔细斟酌的方面是自动驾驶汽车在特定情况下的伦理反应。人们经常援引“电车难题”来讨论自动驾驶汽车可能面临的棘手的伦理抉择。例如，自动驾驶汽车内的人是否应该始终受到优先保护，即使这意味着危及行人的生命?为避免撞到一群行人，自动驾驶汽车是否应该去撞一个行人?

这个行人如果是一个小孩或老人，自动驾驶汽车会作出不同的决定吗?如何编写程序让自动驾驶汽车合乎伦理，这个问题带来的伦理困境尚待解决。Besidessuchethicalconcerns,thelegalsituationstheAVindustryislikelytobeconfrontedwithhavefuelledheateddebates.Inthisemergingindustry,manufacturingandprogrammingstandardsarenotyetuniform.Moreover,thequalityandsafetyofAVtechnologyisstillbeingchallenged.Thiscouldleadtoextraordinarycaseslikewhoshouldbeheldresponsiblewhenself-drivingcarsareinvolvedinaccidents-shoulditbethedriver,thesoftwareprogrammerorthemanufacturer?Manufacturingandprogrammingstandardsfirsthavetobeagreedupontomakeitpossibleforlawcourtstodecidewhoisatfaultwhenthingsgowrong.AsadvancesinAVdesignandtechnologyareinprogress,thefinalagreementonlawsandregulationsinthisindustryremainstobeseen.除了这些道德方面的担忧，自动驾驶汽车行业可能面临的法律处境已经引发了激烈争论。在这个方兴未艾的行业里，制造和编程标准尚未统一。此外，自动驾驶汽车技术的可靠性和安全性依然受到质疑。这会导致一些意想不到的情况，例如，当自动驾驶汽车发生事故时，责任该由哪一方承担一

是

自动驾驶汽车的司机，软件程序员，还是生产商?首先要有统一的制造和编程标准，法庭才能在出现问题时裁定谁有过错。自动驾驶汽车的设计和技术正在不断进步，而管理该行业的法律法规的最终-致尚待确定。

年首次亮相的“复兴号”电力动车组(EMU)是彰显高铁设计和建设专门]技术的又一项卓越成就。

“复兴号”完全由中国研发和制造，功能现代化，设计优雅，技术先进，优于以往车型。它使用寿命更长，并配有降低风阻的节能设计。所有这些成就展示了工程师的全身心投入、铁路工人的不懈努力以及全体中国人民的大力支持。
