2021年上海车展前夕,搭载华为自动驾驶系统ADS的北汽极狐阿尔法S华为HI版车型的实测视频开始在网上刷屏。视频中的华为ADS在交通复杂的闹市表现出了极高的算法鲁棒性,宛如一个驾龄多年的老司机。
华为自动驾驶量产的横空出世引起了所有人的关注,其引发的热度不亚于两年前的那个上海车展,华为低调到访,宣布全面进军汽车产业。
这似乎是华为一贯的风格,不鸣则已,一鸣惊人。
4月16日,类星频道来到华为上海研究所,采访了华为ADS的负责人苏箐。苏箐从海思芯片做起,曾领导开发了华为达芬奇AI芯片架构,目前担任华为汽车BU智能驾驶产品线总裁、首席架构师。
苏箐是那种能迅速俘获媒体的被访者。他思维敏捷、语速极快、对自动驾驶有非常前瞻的视野,并极度自信,并不吝于分享对业内其他企业的看法——当然,在讲完后也不忘非常职业地补充一句:这是我个人看法,不代表公司立场。
我们整理了类星频道和其他媒体采访苏箐的实录,一刀未剪,Enjoyit。
关于阿尔法S华为HI版
媒体:现在咱们的系统支持在哪些城市使用?
苏箐:可能简单先讲一下系统几个模式的构成,不是一个简单的Robotaxi,它有NCA、ICA和ICA+这个模式,我想你可能问到的问题和今天体验的主要是NCA模式,NCA模式是完全全自动的,有点像Robotaxi的体验。
在今年底量产的时候,我们会开放北上广深四个城市,大约每三个月我们会开放一批新的城市,这个是NCA的体验。我们也看到国内毕竟还有很多二线、三线、四线城市,大家也要买车也要用,这个时候我们会提供一个ICA+的模式,因为我们车会自学习整个的交通环境和自构图。
这个车只要你开过,或者你的邻居伙伴开过,这个车会自动学习这个的路况,它会实时去构图,然后这个车会达到一个类似于Robotaxi,但是肯定会稍微差一点,因为它的数据不够全,会达到这样的体验。
特别是现在比较火的highway,包括像上海的内环、中环、外环是完全不需要地图的,可以达到基本一样的体验。所以这个东西是可以在全国今年年底就泛化的,没有任何问题。
媒体:后面每三个月一个城市?
苏箐:不止一个,每三个月一批。
媒体:一个季度大概的量是多少?
苏箐:现在没法说,也许一开始6个?我只是举个例子,大概这样的水平。
媒体:现在的测试范围是怎么样的?
苏箐:全国已经都在泛化了,一二线城市都在泛化。
媒体:能把所有的硬件配置讲一下吗?
苏箐:我们有两个配置,标准版的是400TOPS的算力,豪华版配800TOPS的算力。
媒体:能说一下激光雷达的寿命吗?
苏箐:激光雷达在乘用车上看到10年没什么问题。
媒体:量产吗?
苏箐:量产的,现货。
媒体:什么时候交付?
苏箐:今年11、12月份。
媒体:我们的车主要在中国哪些地区测试?
苏箐:第一是北上广深,北上广深是重点跑的,其他是全国的高速路网,所有主要城市的环路也在跑,这是第一批要覆盖的。我们很快,下半年开始在二线城市跑。
媒体:我们说的北上广深是全市所有道路吗?
苏箐:全市所有,但北京有点特殊。北京从法规上五环以内进不去。
媒体:这两天没有体验到AVP的功能,这块的研发进度和量产规划怎么样?
苏箐:AVP其实是最早完成的一部分,我以为大家可能对泊车可能已经比较没太大兴趣了,下次可以安排大家体验一下,因为 AVP我们的量产车里面肯定是最好的,大家应该会很惊艳。
媒体:能够做到L4级AVP吗?人可以下车?
苏箐:我觉得是这样,大家现在总是喜欢讲脱手、脱眼、脱脚,我知道作为融资也好、噱头也好是很好的,但是说实话,我自己做自动驾驶这么多年,我其实很不喜欢这个说法。
我觉得更需要解决的不是在某一个特定的商业区或者是特定的Building搞一个Demo,这个不是我要干的事情,我要解决的是解决你每天上下班通勤的问题。
明显一个问题是你不可能对每一个上下班的人群、工薪族,你对他的Office和家里面的小区,把他这个地图和车库的地图全部建出来,这是不可能的,没有任何人能做到这一点。
我愿意解决的是用车的自学习技术,去解决每个人每天上下班自己的办公室和家的车库的自动泊车。
第一步我要追求的不是这个人下车,离开车,我要追求的是这个人到了小区门口的闸机的地方,车就告诉你你现在不用再管它了,你只要激活这个功能以后,车会自动帮你停到车位里面去,这是我第一步解决的问题。
媒体:您提到的NCA、ICA+、ICA,能不能简单展开讲一下?
苏箐:简单点说,NCA模式就是大家看到的车内有预制的高精地图的,ICA+是没有高精度地图的,但是车会根据自车或者是他车开过的环境自动学习地图,这就是ICA+。
在你第一次开的地方,总有这种地方,谁也没开过,别人车也没有开过,这是完全的ICA模式,大家看到特斯拉现在就是ICA模式,分这三种。
媒体:像在ICA+模式下用户的感受怎么样?
苏箐:你会发现ICA+是基于NCA和ICA中间的一个地带,你车开过的次数越多,或者是他车开过的次数越多,他的体验就会越向NCA这边靠拢。而开得比较少的时候,开一次的时候体验有点像ICA,它是逐步提升的自我学习的过程。
媒体:可以理解为有没有地图,可能这个系统的信心不一样,在某一种情况下比较容易退出?
苏箐:我简单点说,你自己去一个陌生复杂的城市,你自己开车会速度会变慢,会变得小心,因为你不知道前面有没有一个豁口,会不会有行人蹿出来,就这种问题,其实是一样的,对车来讲它也有这样的问题。
媒体:昨天咱们工程师说降级到ICA+以后没有办法实现点对点?
苏箐:不完全对,说点对点,意思就是任何出发的时候在地图里面都可以搜索这个目标点。但是在ICA+的时候,理论上是没有全局地图的,那么在你去过的地点,简单点就是每日通勤的上下班这个点因为你开过,所以其实是可以实现的。
但是如果你要泛化到所有地点上去,它确实是实现不了的,你可以理解它的地图是不完整的一个地图,你这么理解这件事情就好理解了。
媒体:因为精度没有高精地图的精度高,所以能力可能会稍微弱一点?
苏箐:地图精度是够的,但是数据是不完整的。我举个例子,你只开过一次的时候,可能你自车车道是被构出来的,你离很远的车道可能是有缺失的,你的对向的车道也是有缺失的,你得开得越来越多才会累计得更完整。
有点像以前打《星际争霸》你记得吗?开始地图是黑的,你开过的地方就白了,就是这样的过程,很像。
媒体:今天我们体验的天气比较好,不知道像暴风雨、台风的天气,还有包括夜间模式和隧道的模式处理得怎么样?
苏箐:隧道没有任何难度,不知道大家为什么老是讲隧道,隧道没有任何难度,隧道只是一个定位问题,没有GPS。但话说回来你在城市里面开,你在高架下开也不能靠GPS混,这个也不现实,除非你做Demo做着玩,这显然没有难度。
暴风雨可以看一下去年我们发车展发的一个视频,相当于是暴雨天气,所以对我们来说也不是问题,还有什么场景?
媒体:夜间?
苏箐:我们有同学体验过夜间模式,夜间也没有什么难度。下雨天因为传感器有遮挡所以车行为会更小心、更保守一点,但是夜间和白天比并没有可见的难度提升。
媒体:我们和北汽如何分工?华为合作的这几家车企有什么差异化?
苏箐:这个是一个好问题,我到现在想看也没有很明确的分工界面,因为大家联合来打造这辆车。
你如果说一定要分的话,北汽可能更多在Cover这个车的机械系统、底盘系统,相对来讲比较传统的部分。
华为帮他搞定整个车的计算机化这一块,包括自动驾驶、座舱,还有后端云端的这些事情,如果长期分的话,大概是这样,其实这个事情也没有这么简单。
差异化坦率点说真的是很严重的问题,你觉得智能机有什么差异化?手机有什么差异化?越是复杂的电子系统,每个主体开发成本达到几十亿美金的时候,不应该在这个地方做差异化。这是有严重问题的。
媒体:华为和北汽的合作是一款车型还是一系列平台?
苏箐:一系列车型,因为这种东西不论对于我们还是对于北汽来讲投资都是非常巨大的,不会只做一个车型。
媒体:长安和广汽也是吗?
苏箐:一样。
媒体:一系列车型什么时候会来?
苏箐:明年上半年到上半年,你会看到有大量的车上市。
媒体:刚才你说我们体验车的完成度只有30%?
苏箐:算法。
媒体:我们自己测试的车能达到百分之多少?
苏箐:不能说100%,一旦变成这样复杂软件系统以后没有100%,每两三个月迭代一次,而且迭代挺大的。拿急刹来说少大概百分之七八十,我只是举一个例子。
媒体:我们做的这个车是多久以前的稳定版?
苏箐:只适配了两个月,版本是一样的版本,它只适配了两个月。
媒体:车企教会了你们些什么?
苏箐:举个简单的例子,一开始所有做Robotaxi的人在车顶上有一大坨,像一个塔一样的传感器塔。
坦白地讲,我们还很羡慕的,那样算法会简单非常多。我们曾经最早做的时候,很多年前,也希望上面放一个塔,哪怕矮一点的塔,被我们一个大客户坚决制止,绝对不允许你这样干。
所以你看到现在的ADS车和普通车长得一样,这就是我们和车厂学到的很重要的一点。
关于华为ADS部门的规划
媒体:ADS有多少人?上这样的一个车大概多长的周期?
苏箐:极狐是深度合作的第一辆车,这辆车本身可能开发应该有3年了,后面应该会快一些,第一代的问题总是比较多的。你可以认为很多后面的导入,我猜应该在24个月左右,再短可能就很难了。
媒体:ADS团队规模有多大?
苏箐:自动驾驶这一块 2千多人。
媒体:关键的研发都在国内吗?
苏箐:都在国内,是的。
媒体:可以讲一下2000多人的团队里面,做盒子、激光雷达和算法的人有什么划分吗,大概占比是多少?
苏箐:你可以认为纯算法1200人左右,算法里面可以分几个大块,我们叫大感知,就是你说的视觉、激光都在大感知团队里面,下面不再分。还有第二个预测,第三个我们叫PNC,规控,PNC里面又会细分。
你可以认为每个团队的规模大概都在200-300人不等,剩下1000人就是做你刚才说的其他东西。
媒体:除了极狐这个车,下一阶段有增加新的车型和品牌吗?
苏箐:有,可能现在公司已经发布了我看到三家,极狐、长安、广汽,后面还有一些其他的大厂,你们后面会看到的。
媒体:是我们ADS出海了还是他们在国内的车型?
苏箐:首先是他们在国内的车型。
媒体:你们对Robotaxi是什么看法?会不会考虑做运营?
苏箐:首先我表达一个个人立场:你打死我我也不会去做Robotaxi。Robotaxi是一个结果,不应该是商业目标。
对美国人来讲,打车体验很差,我这么多年去美国出差,体验非常非常差;中国打车体验非常好,说实话也不贵,你如果真的说Robotaxi,那中国早就实现了,只不过那个Robo是个人,这个体验一点问题也没有。
今天你把它变成计算机了,这个体验一点儿都不会变好,坦白讲。我坚决不认为这东西会改变体验的基本盘、出行的基本盘,在中国,坚决不会。
第二,Robotaxi是一个最难的问题,从技术上讲,因为它需要扫掉所有的Cornercase。所以我为什么说他是一个结果,你在所有事都完美之前,一定有一个漫长的不完美的过程,你需要接管。
随着时间的演进和技术的成熟,总有一天能实现。但这个时间会非常非常长,需要大量的车,绝不是大家今天说的几万辆车。
什么时候你敢说这句话,什么时候你几十万几百万辆车跑N年,数据告诉你可以了,你才可以。所以说它是一个结果,它不应该作为目标。
我的个人看法:所有以Robotaxi为商业目标的公司,都得完蛋。而最后达到Robotaxi的,是做乘用车的人,那个市场一定是我的,但不是现在。
媒体:除了北汽之外,华为的长安、广汽几家车提供打造汽车,华为为什么会选择这几家车企呢,在合作之中华为的参与程度大概是怎么样的?
苏箐:选择客户的原因非常多,说实话国内合作伙伴的速度确实比国际厂要快,这也是大家能看到国内车厂东西先出来的原因,这可能也是中国速度的原因。
第二个选择几个车厂的原因各自不同,像北汽第一个客户这样,北汽非常有诚意,合作得非常好。今天你看到华为的方案还不错,三年前你看到的可能并不是这样的,也许那时候真的是一个原形的东西,那个时候北汽选择相信华为,和华为深度合作。
而且他们在自动驾驶底盘上面,调校方面真的做了很多的工作,这是和北汽深入合作的一个很大的原因。
长安其实也类似,都是有类似的故事,这里面当然有不同的原因,当然也有商业利益。
媒体:华为车BU里自动驾驶的优先级是怎样的?
苏箐:从我的角度来看的话,自动驾驶是绝对的第一,不是一点点的第一。
媒体:自动驾驶这方面华为未来的投入计划是多少?
苏箐:我们现在是2千多个人,一年大概花掉10亿美金,我猜未来应该会保持每年30%左右的增长速度。
华为自动驾驶在国内属于第几梯队的?
苏箐:绝对是第一。
媒体:未来的付费模式是什么样的,未来消费者购买这个车以后是一次性付费?
苏箐:有两种。第一,一次性付费模式。第二,订阅模式。这两种都会有。
媒体:订阅模式跟华为有关系吗?
苏箐:有关系,跟车厂分成,我做的东西为什么跟我没关系呢?
媒体:ADS这个部门什么时候能够盈利?
苏箐:我不着急,华为公司每做一件事情都是10年盈利,我现在唯一要做的事情把技术做到全球最顶尖,然后解决真正的问题。自动驾驶,其实我觉得不用担心盈利的问题。
我举个例子,我记得2006年开始,那个时候都是诺基亚很流行。我们那时候跟公司说要做智能机,一堆人说你疯了,拿咨询公司报告跟我说用户渗透率才0.000几,完全是发烧友的玩具,是你们这些理工男的玩具,说这东西能有什么市场。
所以首先是判断这个东西大势上对还是不对。如果对的话,市场是不用担心的,取决于你能不能把它做好。
关于自动驾驶的监管与责任
媒体:这个车的安全责任是怎么划分的?
苏箐:我们一贯坚持体验式往上做,做到L4这个级别的,但是从法律上就是L2,这个是没有任何含糊的。
而且我觉得如果自动驾驶想发展得迅速,能给大家带来更好的体验,必须这么做。就是把功能、体验和法律责任解耦,否则车厂会非常小心,给你提供最安全的,但是基本等于废物的功能,其实我们看到很多车厂就这么干的。
媒体:自动驾驶什么时候能跨过L2这个阶段?现在法规已经有些松动了?
苏箐:我坦白点讲,大家现在拿法规说事儿的都是骗人的,就是技术问题。
今天你已经看到我们的车已经是L4了,但是我明确告诉你,我不敢让驾驶员离开那个车。你做到1000公里哪怕10000万里接管一次,其实很快就跑到了对吧。在MPI做到极其大之前,不要谈什么L4,都是Demo。
然后大家一谈到这里就拿法律说事儿,我真的看到中国的法律已经非常非常宽松了,国家对自动驾驶是非常支持的,大家再把法律拿出来我觉得是不合适的。
关于华为ADS的技术
媒体:自学习的地图是传到云端,然后从云端再分发给所有车辆吗?
苏箐:取决于不同车厂的选择,这个可以始终保持在车端,也可以在云端重新再做融合。
媒体:那华为提供能做到最好的方案,光凭借车端或者是量产车,其实不需要通过做地图的车就可以把高精地图跑起来吗?
苏箐:如果你是解决每日通勤,点对点的上下班路线的话是可以的。
媒体:NCA是华为自己应用咱们车队做高精地图数据的采集吗?
苏箐:我们有两个部分,其实这样要简单介绍一下我们的系统,我们整个地图系统叫Roadcode,Roadcode里面有两部分组成,一个叫RoadcodeHD,一个叫RoadcodeRT。
HD的意思你可以理解为大家认为的传统的高精度地图,有专门的地图制作团队做的,是离线的。RoadcodeRT是车子的自学习地图。这两个东西是两位一体的。
我自己以前没有做这行也没有注意到整个城市的基建变化原来如此迅速,我发现整个上海的城市道路不停地翻新,红绿灯的更换速度比我想象快得多,如果你只是用RoadcodeHD传统的技术,你很快就挂掉了。
所以RoadcodeRT本身会不断地自学习后去更新HD,把数据沉淀下来,这样的沉淀迭代循环的过程。
媒体:昨天晚上我们发现车辆侧面遇到外卖小哥会比较纠结,这个有什么好的解决办法吗?
苏箐:你说的是对的,你会发现这个量产车它在侧后方的激光覆盖是有盲区的,它要靠视觉去补。另外这个车现在并不是最终量产的状态。这个车实际上,真正北汽从把底盘调到能用,能上路调自动驾驶是春节以后的事情,只有两个月的时间。
所以这个事儿你可以理解为算法完成度只有30%-40%。等你买到的时候这个问题一定会解决的。
媒体:这个解决办法是增加传感器吗?
苏箐:不不不,优化算法。
媒体:只依靠视觉能精确的对侧面的物体进行精确的位置检测吗?
苏箐:这个车其实有两圈视觉传感器,一圈远距的,还有一圈鱼眼,鱼眼我们也用了。
你会发现视觉的特点是,距离越远的时候,它的测量误差越大。当距离缩短的时候,它的测量精度会迅速提高,甚至可以比激光更高。
你这个问题是一个旁车道或者说nearcut-in的问题,这时候近距离的视觉测距是没有大问题的,从原理上来讲是如此。
媒体:所以我们在行车的工况,不止泊车工况会调用环视?
苏箐:当然,不然不是浪费吗?
媒体:想问一下前融合,既然是前融合,所有的这些信息都会归纳到一整套的计算中心或者是神经网络里面去消化它吗?
苏箐:你可以认为所有的信息都是网络的输入,但是不是一张网,不同的网络完成的功能不一样。
媒体:你们提过可以做到1000公里无接管,这个数据怎么得出来的?
苏箐:实话说MPI这个数据对衡量自动驾驶,到目前位置我没有找到更好的指标,但是 MPI这个值里面有很多的计算技巧和技术方法的,这是为什么我不愿意谈这个问题。
你可以看得到,简单点说MPI跟几个东西有关系:
第一,跟统计方法有关系,然后是跟时空有关系,时空的意思就是你选什么样的路段在什么时间去跑,跟这三个东西全都有关系,这里面的值可以差到一个数量级。
为什么刚才说的跟统计方法有关?我们可以看到加州的统计结果,如果你有几百辆车的时候,在一定时间内可以挑出比较好的样本和比较好的时间连续段统计它,MPI值会很漂亮。
我们内部这样去做MPI值的时候坦白点讲没有什么意义,更多是把所有的车,在所有时间段内做历史累计,这个时候算的统计意义的MPI才是一个真实的MPI。
我能讲的是任何MPI在自动驾驶团队里面都是核心机密,我坦白点讲不能告诉你一个具体的数字,它也不是一个简单的数字,是一个很大的表。在所谓加州的统计方法里面,我在上海确实可以做到1000。
但是在真实的历史统计上面我只能说我还没有做到1000,这个我必须告诉你,而且我敢打赌,全世界包括Waymo在内也没有人能够做到1000。
媒体:你们的自学习和特斯拉的影子模式会有区别吗?
苏箐:我说实话特斯拉到现在的模式看到的只是概念,没有解释过细节,从我们实践上来看至少有几块东西,你管它叫影子模式也好,管它叫车端智能也好。
我们有两个大的技术,一个就是刚才说的RoadcodeRT,这个是解决了整个交通静态环境的一个自学习、自构图的问题,包括刚才说的AVP也是靠这个来实现的。
另一个就是我们管它叫DDI,DDI可能也许更像你说的影子模式,就是DDI会不断学习这个车主的驾驶行为,不见得是接管,可能车本身的行为跟车主不一致的,他会抓取车主的行为去做迭代,也许是你说的影子模式。
媒体:你们的前视觉感知很独特。
苏箐:哪里独特?
媒体:四个摄像头,长焦+广角+双目,量产车里不多见。
苏箐:对,因为双目比较难,大家其实都没搞成,只是我们搞出来了而已。
媒体:双目你们解决了什么问题?
苏箐:双目一大堆问题,简单点说从机械上有标定的问题,从算法上其实想把双目用好并不容易,因为双目要解决的本质问题是深度测量,但深度测量本身想测量比较稳定、可泛化其实是很难的问题,大多数做双目的只能做到二三十米,我们远远超过这个数据。
媒体:目前这套架构有了三个激光雷达,还有很多摄像头。这套架构在其他车型上做到,传感器数量和传感器类型上基本上不会大多?
苏箐:差不多,你会看到在这一代车里面都会差不多,我们一般会在每18个月做一次做小幅度升级,不断往上迭代。
媒体:你刚刚说自动驾驶可能要几百万辆车,现在特斯拉已经有一百万辆了。
苏箐:好问题。我记得以前谁讲过一个问题很有道理。什么叫大数据?大数据的重点不是‘大’字,是数据质量和全,这个是大数据的本质,自动驾驶其实很像。数据里面两个问题很关键。第一,数据本身的质量。第二,数据的维度。
在这两个问题上,我觉得特斯拉的数据有大问题。
什么叫维度?仅仅靠简单的几个视觉搜集的数据,这个数据高精定位什么都没有的时候,维度是非常低的。明显看到ADS的车数据维度比它高好几个数量级,数据维度极其重要,数据维度代表信息丰富度和差异化程度。
第二,数据本身的质量。你会发现数据本身是用算法催生的,你低阶系统本身复杂度导致数据本身质量比较低,特斯拉目前是在这个状态,要我猜,特斯拉的数据早就饱和了,对系统能力没有提升。
其实我们自己现在拿ADS来说缺的不是数据,而是算法有很多难题需要解,我现在绝对不缺数据。
媒体:解决这些难题,第一个逻辑是感知到位,第二个逻辑是对对方车辆的预测到位,哪一块更难?
苏箐:好问题。我们第一天刚干感觉特别难,后面干着觉得预测难,预测完了以后大家觉得规控难,现在规控也难完了,大家回来发现感知也挺难,不断地在循环。
你一定要我说的话,业界整体技术复杂来讲,一开始说感知难度,这是所有人都知道的。要我说,业界从理论和技术成熟度来说,预测和规控两个问题才是真正的难题,这两个问题可能很多人没意识到。
媒体:算法主要靠神经网络深度学习,深度学习有时候会有黑盒,您觉得未来算法上会不会有突破?
苏箐:第一个,自动驾驶系统里面不仅仅是神经网络,神经网络在里面只是其中一切部分东西。算力来讲它占绝对的大头,代码规模上绝对不是,首先澄清一下这个问题。
第二个,我坚决不同意AI是一个黑盒的说法。它的计算模式从以前CPU的标量计算或者线性计算变成了基于线性代数的概率计算,它从概率角度是完全可解释的,一点问题都没有。
你可以认为是概率学、统计学的东西和以前1+1=2的东西,不能说概率学和统计学不能解释,我完全不同意这个观点。
关于自动驾驶系统的冗余
媒体:所以我们远距离是依靠激光雷达?
苏箐:不我们不是这样分的。以前大家老是问一个问题,你们的感知是前融合还是后融合还是什么Redundancy(冗余)的技术?
首先我觉得传感器没有Redundancy这一说,这是胡扯。然后后融合技术在两年以前被我们抛弃了,现在我们全部都是前融合的技术。
前融合的特点其实是把所有的信息放在一起,送到NN网络里去处理,它并不是一个简单的哪个传感器用哪个信息的问题。你也可以简单理解为传感器之间互相会有Attention机制。
另一个,不同传感器的特点是不一样的。举个例子,毫米波速度敏感,但测量一塌糊涂,视觉对语义测得比较好;激光对几何测量是比较好的,它本身会把这些融合在一起。
毫米波我们是直接把毫米波的原始数据拿过来了,用它的原始点云。
媒体:找供应商拿原始数据会有难度吗?
苏箐:两个问题,第一大部分Tier1不愿意开放原始数据给你,但华为比较大嘛,人家也愿意开放,第二其实毫米波的原始数据是比较脏的,其实比较难处理,我们现在用NN在处理。
媒体:双目做激光的冗余吗?
苏箐:这个东西不能叫冗余,其实不同的传感器,不同的表现、优劣是有一个波动的。
媒体:有一家头部自动驾驶公司提出了真冗余,把雷达、LIDAR作为一个子系统,把纯视觉作为一个子系统,独立测试,两个子系统接管率相乘来实现统计学意义上所需测试里程的降低。
苏箐:坦率的说,我猜那个是他们Marketing写的,绝对不是他们研发写的,否则我就要怀疑他们的研发能力了。真正决定你接管率的,绝不仅是你的感知系统,跟你的规控关系非常大,甚至比感知系统还要大。
这些系统是没有你所谓的真冗余设计的对吗?
第二,绝大多数那些难以处理的case,你加上80倍的传感器也处理不了。我敢跟你打赌。所以这种乘的算法来做统计的逻辑是很荒唐的。
真冗余是很Marketing的说法,你要把感知做好,你就应该做传感器融合,而不是做冗余,做冗余是对传感器很严重的浪费。他们的技术水平绝对不是这样。
关于ADS的竞争对手
媒体:一些跨国企业还在打L3的概念,但是华为坚持的是连续性优化,您怎么看这种传统大厂再去往责任上突破,而我们再去往连续性上突破两种不同的差异?
苏箐:其实你看欧洲大家的想法也不完全一样,我做一个个人评价,不代表公司的立场。
我个人觉得欧洲的三大里面,BBA里面大众其实思路上比较靠前,跟他们做了这么多年自动驾驶的探索是有关系的。其他家的思路还在一个演进的过程中。
其实特斯拉,不好意思,还是要提特斯拉,特斯拉我觉得教会了所有人,包括我们在内和车厂很多事情。
车厂你看到了,你会发现一个行业本质上变化是什么?你再往前看就清楚了。
扯远一点,大家以前是蒸汽机、电动汽起来以后能源革命或者是动力革命,然后计算机被发明了,然后计算机在改变所有东西,其实过去三四十年就是这个过程,计算机在改变所有东西,上次把手机给改了,这次把车给改了,这个是我们跟特斯拉的看法,都是这样的看法。
传统的车厂他的看法首先我的基座是车,现在有些计算机的单点,那么我是把车作为一个基础,然后我试图把计算机嵌进去,这是传统车厂的看法。
我们的看法不一样,我们的看法基础是计算机,车是计算机控制的外设,这是本质看法不一样,会导致所有事情看法都不一样。
所以你会看到传统车厂以这个为思路会做很多小盒子,来一个功能加一个盒子,来一个功能加一个盒子,但是我们的看法本身就是一台计算机,一个大计算机了事,把车挂上去,这是本质的不同。
媒体:所以这是华为不造车根本的原因吗?
苏箐:不造车我觉得是一个商业选择的问题,不造车算下来市场更大。
This article is from the official Wechat account: star Channel, author: Chris Zheng
On the eve of the 2021 Shanghai auto show, the actual video of BAIC's polar fox Alpha S Huawei HI model with Huawei self-driving system ADS began to scan the screen online. The Huawei ADS in the video shows a high robustness of the algorithm in a busy city with complex traffic, just like a veteran driver who has been driving for many years.
The emergence of Huawei's autopilot production has attracted everyone's attention, causing as much heat as the Shanghai auto show two years ago, when Huawei made a low-key visit and announced a full-scale foray into the auto industry.
This seems to be the consistent style of Huawei. If you don't make a sound, it will be a blockbuster.
On April 16, the Star Channel came to Huawei Shanghai Research Institute to interview Su Qing, the head of Huawei ADS. Starting with Hayes Chip, Suqing led the development of Huawei Leonardo da Vinci AI chip architecture and is currently the president and chief architect of Huawei's BU smart driving product line.
Suqing is the kind of interviewee who can capture the media quickly. He is quick-thinking, speaks extremely fast, has a very forward-looking vision for self-driving, and is extremely confident, and is not hesitant to share his views on other companies in the industry-of course, he does not forget to add professionally: this is my personal opinion. It doesn't represent the position of the company.
We sorted out the actual records of Suqing interviewed by the quasi-Star Channel and other media, without a cut, Enjoyit.
About Alpha S Huawei HI Edition
Media: which cities does our system support now?
Suqing: maybe I'll briefly talk about the composition of several modes of the system first. It's not a simple Robotaxi, it has NCA, ICA and ICA+ modes. I think the questions you may ask and what you experience today are mainly NCA mode. NCA mode is completely automatic, a bit like the Robotaxi experience.
When we are in mass production at the end of this year, we will open four cities in the north, Shanghai, Guangzhou and Shenzhen, and we will open a batch of new cities about every three months. This is the experience of NCA. We can also see that after all, there are still many second-tier, third-tier and fourth-tier cities in China, and everyone has to buy a car and use it. At this time, we will provide an ICA+ model because our cars will learn the whole traffic environment and self-composition map by themselves.
As long as you have driven the car, or your neighbor has driven it, the car will automatically learn about the road conditions, it will make up the picture in real time, and then the car will reach a similar Robotaxi, but it will definitely be a little worse, because its data is not complete enough to achieve such an experience.
In particular, the more popular highway, including the inner ring, central ring and outer ring of Shanghai, do not need a map at all, and can achieve the same basic experience. Therefore, this thing can be generalized by the end of this year, and there is no problem.
Media: a city every three months?
Suqing: more than one, one batch every three months.
Media: what is the approximate volume in a quarter?
Suqing: I can't tell now, maybe six at the beginning? I'm just giving an example, about this level.
Media: what is the scope of the test now?
Suqing: the whole country is already in generalization, and the first-and second-tier cities are all in generalization.
Media: can you tell me all the hardware configurations?
Suqing: we have two configurations, the standard version is the computing power of 400TOPS, and the deluxe version is equipped with the computing power of 800TOPS.
Media: can you tell me the life of lidar?
Suqing: it's no problem for lidar to see it on a passenger car for 10 years.
Media: mass production?
Suqing: mass production, spot.
Media: when will it be delivered?
Suqing: November and December this year.
Media: in which parts of China will our car owners test?
Suqing: the first is to go north to Guangzhou and Shenzhen, the other is the national highway network, and the ring roads in all major cities are also running, which is the first batch to cover. We began to run in second-tier cities in the second half of the year.
Media: are we talking about all the roads in the city?
Suqing: it's all in the city, but Beijing is a little special. Beijing cannot enter from within the Fifth Ring Road of the law.
Media: I haven't experienced the function of AVP in the past two days. What's the R & D progress and mass production plan of this area?
Suqing: AVP is actually the first part to be completed. I think you may not be very interested in parking. We can arrange for you to experience it next time, because AVP is definitely the best of our mass production cars, and everyone should be amazing.
Media: can you achieve L4 AVP? People can get off?
Suqing: I think so. Now people always like to get rid of their hands, eyes and feet. I know it's good as a financing or a gimmick, but to be honest, I've been on autopilot for so many years. I actually don't like that.
I think what needs to be solved more is not to set up a Demo, in a specific business district or a specific Building, which is not what I want to do, what I want to solve is to solve the problem of your daily commute to and from work.
Obviously, one problem is that it is impossible for every commuter, wage earner, his Office and the community at home to build this map and the map of the garage, which is impossible, and no one can do it.
What I would like to solve is to use the car self-learning technology to solve the automatic parking of everyone commuting to and from his office and home garage every day.
What I want to pursue in the first step is not that this person gets out of the car and leaves the car. What I want to pursue is that when this person arrives at the gate of the community, the car will tell you that you don't have to worry about it now. As long as you activate this function, the car will automatically park you in the parking space. This is the problem I solved in the first step.
Media: can you briefly expand on the NCA, ICA+ and ICA, you mentioned?
Suqing: to put it simply, the NCA model is that you can see that there are prefabricated high-precision maps in the car. ICA+ does not have high-precision maps, but the car will automatically learn the map according to the environment of the car or the environment he has driven. This is ICA+.
In the place where you drive for the first time, there is always such a place, no one has ever driven, no one else has driven a car, this is a complete ICA mode, we can see that Tesla is now an ICA mode, divided into these three.
Media: how do users feel like in ICA+ mode?
Suqing: you will find that ICA+ is based on a zone between NCA and ICA. The more times you drive, or the more times he drives, the closer his experience will be to NCA. When you drive less, the experience is a bit like ICA, which is a self-learning process of gradual improvement.
Media: can be understood as whether there is a map, maybe the confidence of this system is different, in a certain case it is easier to quit?
Suqing: to put it simply, if you go to a strange and complicated city by yourself, you will slow down and be careful because you don't know if there is a gap in front and whether pedestrians will jump out. This kind of problem is actually the same, as far as cars are concerned.
Media: yesterday our engineer said that there is no way to achieve peer-to-peer after being downgraded to ICA+?
Suqing: not exactly, point-to-point, which means that you can search this target point on the map at any time of departure. But in ICA+, in theory, there is no global map, so in the places you have been to, the simple point is to commute to and from work every day, which is actually possible because you have driven it.
But if you want to generalize to all locations, it really can not be achieved, you can understand that its map is an incomplete map, it is easy for you to understand the matter in this way.
Media: because the accuracy is not as high as that of high-precision maps, so the ability may be a little weaker?
Suqing: the accuracy of the map is enough, but the data is incomplete. Let me give you an example, when you only drive once, your bike lane may be constructed, your far away lane may be missing, your opposite lane may also be missing, you have to drive more and more to be more complete.
It's kind of like playing StarCraft, remember? At first, the map is black, and the place you drive is white. This is the process, very similar.
Media: the weather we experienced today is better. I don't know how to deal with weather like storms and typhoons, as well as night patterns and tunnels.
Suqing: there is no difficulty in the tunnel. I don't know why people always talk about the tunnel. There is no difficulty in the tunnel. The tunnel is just a positioning problem and there is no GPS. But then again, if you drive in the city, you can't rely on GPS even if you drive under the viaduct, which is not realistic, unless you are doing Demo for fun, which is obviously not difficult.
The storm can take a look at a video released by our car show last year, which is equivalent to heavy rain, so it's not a problem for us, is there any other scene?
Media: at night?
Suqing: some of our classmates have experienced the night mode, and it is not difficult at night. On rainy days, cars behave more carefully and conservatively because the sensors are blocked, but there is no visible difficulty at night and during the day.
Media: how do we divide our work with BAIC? What is the difference between these car companies that Huawei cooperates with?
Suqing: this is a good question. I still don't have a very clear interface for division of labor, because we all work together to build this car.
If you must share, BAIC may be more in the relatively traditional part of the mechanical system and chassis system of the Cover.
Huawei helps him with the computerization of the whole car, including autopilot, cockpit, and back-end cloud. If you divide it for a long time, it's probably like this, but it's not that simple.
Differentiation frankly is a serious problem. What do you think is the difference between smartphones? What is the difference between mobile phones? The more complex the electronic system, when the development cost of each subject reaches billions of dollars, it should not be differentiated in this place. This is a serious problem.
Media: is the cooperation between Huawei and BAIC a model or a series of platforms?
Suqing: a series of models, because this kind of thing is a huge investment for us and BAIC, and it will not be just one model.
Media: are Changan and GAC, too?
Suqing: same.
Media: when will a series of models come?
Suqing: from the first half of next year to the first half of next year, you will see a large number of cars on the market.
Media: just now you said that the completion rate of our experience car is only 30%?
Suqing: algorithm.
Media: how many percent of the cars can we test by ourselves?
Suqing: you can't say 100%. Once you become such a complex software system, there is no 100%. It is iterated every two or three months, and the iteration is quite large. Take the emergency brake as an example, it is about 70% or 80% less. Let me just give an example.
Media: how long ago is the stable version of the car we made?
Suqing: it only adapted for two months, the version is the same version, it only adapted for two months.
Media: what have car companies taught you?
Suqing: to take a simple example, at first all the people who made Robotaxi had a big pile of sensor towers on the roof of the car, like a tower.
Frankly speaking, we still envy that the algorithm would be much simpler. When we first did it, many years ago, we also wanted to put a tower on it, even a shorter one, which was firmly stopped by one of our big clients, and you would never be allowed to do so.
So you can see that today's ADS cars look the same as ordinary cars, and this is a very important point that we and the car factory have learned.
On the Planning of Huawei's ADS Department
Media: how many people are there in ADS? How long does it take to get on such a car?
Suqing: the polar fox is the first car with deep cooperation. The car itself may have been developed for 3 years, and it should be faster later. There are always many problems in the first generation. You can think of a lot of later imports, I guess it should be about 24 months, any shorter may be very difficult.
Media: how big is the ADS team?
Suqing: there are more than 2,000 people on autopilot.
Media: are the key R & D in China?
Suqing: all in China, yes.
Media: can you tell me about the division of the people who make boxes, lidars and algorithms in a team of more than 2000 people, and what is the proportion?
Suqing: you can think that there are about 1200 people in the pure algorithm, which can be divided into several large chunks. We call it big perception, that is, the vision and laser are all in the big perception team. There is also a second prediction, and the third is called PNC, regulation, which will be subdivided in PNC.
You can think that the size of each team is about 200,300 people, and the remaining 1000 people are just doing the other things you just said.
Media: in addition to the polar fox, are there any new models and brands to be added in the next stage?
Suqing: yes, maybe now the company has released three, Jihu, Changan, Guangzhou Automobile, and there are some other big factories behind, which you will see later.
Media: is it our ADS going out to sea or their domestic models?
Suqing: first of all, their models in China.
Media: what do you think of Robotaxi? Will you consider doing business?
Suqing: first of all, I would like to express a personal position: I will not do Robotaxi even if you kill me. Robotaxi is a result and should not be a business goal.
For Americans, the taxi-hailing experience is very poor. I have been on business trips to the United States for so many years, and the experience is very poor; the taxi-hailing experience in China is very good, and to be honest, it is not expensive. If you really say Robotaxi, then China has already realized it, but that Robo is an individual, and there is no problem with this experience at all.
Today you turn it into a computer, and the experience is not going to get any better, frankly. I firmly do not think that this thing will change the basic disk of experience, the basic disk of travel, in China, absolutely not.
Second, Robotaxi is one of the most difficult problems, technically, because it needs to sweep away all Cornercase. So why do I say that he is a result? you must have a long and imperfect process before everything is perfect, and you need to take over.
With the evolution of time and the maturity of technology, it can be realized one day. But it will take a very long time, and it will require a large number of cars. It is by no means tens of thousands of cars as we are talking about today.
When you dare to say this sentence, when you have hundreds of thousands of millions of cars running N years, the data tell you can, you can. So it is a result, it should not be a goal.
My personal opinion: all companies that aim at Robotaxi are doomed. And the last person to reach Robotaxi is the passenger car, that market must be mine, but not now.
Media: in addition to BAIC, Huawei's Changan and Guangzhou Auto provide several cars to build cars. Why did Huawei choose these car companies? what is the degree of Huawei's participation in the cooperation?
Suqing: there are many reasons for choosing customers. To be honest, the speed of domestic partners is indeed faster than that of international factories. This is also the reason why you can see that domestic car factories come out first, and this may also be the reason for China's speed.
The second reason for choosing several car factories is different. Like BAIC's first customer, BAIC is very sincere and cooperates very well. Today, you see that Huawei's plan is not bad. What you saw three years ago may not be like this. Maybe it was really a prototype thing at that time. At that time, BAIC chose to trust Huawei and cooperate deeply with Huawei.
And they have really done a lot of work on the self-driving chassis, which is a big reason for the deep cooperation with BAIC.
In fact, Chang'an is also similar, there are similar stories, of course, there are different reasons, of course, there are also commercial interests.
Media: what is the priority of autopilot in Huawei BU?
Suqing: from my point of view, autopilot is absolutely the first, not a little bit of the first.
Media: what are Huawei's future investment plans for autopilot?
Suqing: there are more than 2, 000 people now, and we spend about $1 billion a year. I guess the growth rate will be about 30% a year in the future.
Which echelon does Huawei autopilot belong to in China?
Suqing: definitely number one.
Media: what will the payment model be like in the future? will consumers pay a lump sum after buying this car in the future?
Suqing: there are two kinds. First, the one-time payment model. Second, subscription mode. There will be both.
Media: does the subscription model have anything to do with Huawei?
Suqing: it has something to do with the car factory. Why does what I do have nothing to do with me?
Media: when will ADS be profitable?
Suqing: I'm not in a hurry. Huawei makes a profit for 10 years in everything it does. The only thing I have to do now is to make the technology the best in the world and then solve the real problem. Autopilot, in fact, I don't think there is any need to worry about profitability.
Let me give you an example. I remember the beginning of 2006, when Nokia was very popular. At that time, we told the company that we wanted to build smart phones, and a bunch of people said that you were crazy and told me that the user penetration rate was only more than 0.000. It was a toy for enthusiasts, and it was a toy for you guys of science and technology, saying that there was no market for this thing.
So the first thing is to judge whether this thing is right or wrong in general. If it's right, the market doesn't have to worry, depending on whether you can do it well.
On the supervision and responsibility of autopilot
Media: how is the safety responsibility of this car divided?
Suqing: we always adhere to the experiential approach, reaching the level of L4, but legally it is L2. There is no ambiguity in this.
And I think if autopilot wants to develop rapidly and bring you a better experience, it must be done. Is to decouple function, experience and legal liability, otherwise the car factory will be very careful to provide you with the safest, but basically equivalent to waste function, in fact, we see a lot of car factories do this.
Media: when can autopilot cross the L2 stage? Is the law a little loose now?
Suqing: let me be frank, what people say about laws and regulations now is a lie, that is, technical problems.
Today you have seen that our car is already L4, but I will tell you clearly that I dare not let the driver leave that car. If you can take over even once in 100 million miles of 1000 kilometers, you will soon get there, right? Before the MPI is extremely big, don't talk about L4, it's all Demo.
Then, as soon as we talk about the law here, I really see that the law in China is already very loose, and the state is very supportive of autopilot. I don't think it's appropriate for you to bring the law out again.
About the technology of Huawei ADS
Media: is the self-learning map sent to the cloud and then redistributed to all vehicles from the cloud?
Suqing: depending on the choice of different automakers, this can always be kept at the end of the car, or it can be reintegrated in the cloud.
Media: then Huawei provides the best solution, relying only on the car end or mass production car, in fact, you don't need to make a map car to run a high-precision map?
Suqing: if you are dealing with daily commuting, point-to-point commuting, it is OK.
Media: NCA is Huawei's own application of our team to do high-precision map data collection?
Suqing: we have two parts. In fact, we want to give a brief introduction to our system. Our whole map system is called Roadcode,Roadcode, which is composed of two parts, one is called RoadcodeHD, and the other is called RoadcodeRT.
The meaning of HD can be understood as what people think of as traditional high-precision maps, which are done by a special map-making team and are offline. RoadcodeRT is a self-learning map of the car. These two things are two in one.
I haven't done this before and haven't noticed that the infrastructure of the whole city is changing so rapidly. I find that the urban roads of the whole Shanghai are constantly renovated, and the traffic lights are changing much faster than I thought. If you just use the traditional RoadcodeHD technology, you will soon be dead.
So RoadcodeRT itself will constantly update HD, to precipitate the data after learning, which is a process of precipitation iterative cycle.
Media: last night we found that the side of the vehicle encountered takeout guy will be more tangled, is there any good solution?
Suqing: you are right. You will find that there is a blind spot in the laser coverage behind the side of this mass production car. It needs to be repaired by vision. In addition, this car is not in the final state of mass production. As a matter of fact, it will only take two months for BAIC to adjust its chassis to be able to use and be able to switch to autopilot on the road after the Spring Festival.
So you can understand that the completion of the algorithm is only 30% and 40%. The problem will be solved when you buy it.
Media: is this solution to add sensors?
Suqing: no, optimize the algorithm.
Media: can the position of the side object be accurately detected only by vision?
Suqing: this car actually has two circles of vision sensors, a long-distance one and a fisheye, which we also use.
You will find that the feature of vision is that the farther the distance is, the greater the measurement error is. When the distance is shortened, its measurement accuracy will be rapidly improved, even higher than the laser.
Your problem is a side lane or nearcut-in problem, at this time close visual ranging is not a big problem, in principle.
Media: so when we are driving, we will look around not only in parking conditions?
Suqing: of course, or wouldn't it be a waste?
Media: would you like to ask pre-fusion, since it is pre-fusion, will all this information be summarized into a whole set of computing centers or neural networks to digest it?
Suqing: you can think that all the information is the input of the network, but it is not a network. Different networks perform different functions.
Media: you mentioned that there could be no takeover for 1000 kilometers. How did you get this data?
Suqing: to be honest, I haven't found a better indicator for measuring autopilot with MPI data so far, but there are a lot of calculation skills and technical methods in the value of MPI, which is why I don't want to talk about it.
As you can see, to put it simply, MPI has something to do with a few things:
First, it has something to do with statistical methods, and then it has something to do with time and space. Time and space means that what kind of road you choose to run at what time has something to do with all three things, and the value can be as low as an order of magnitude.
Why does what I just said have something to do with statistical methods? We can see the statistical results in California. If you have hundreds of cars, you can pick out better samples in a certain period of time and count it continuously for a better period of time, the MPI value will be very beautiful.
When we do the MPI value in this way, frankly speaking, it doesn't make any sense. It's more likely to accumulate all the cars in all the time. At this time, the statistical significance of MPI is a real MPI.
All I can say is that any MPI is a core secret in the autopilot team. Frankly, I can't tell you a specific number, it's not a simple number, it's a big watch. In the so-called California statistical method, I can really do 1000 in Shanghai.
But in terms of real historical statistics, I can only say that I haven't reached 1000, which I have to tell you, and I bet no one in the world, including Waymo, can do 1000.
Media: will there be any difference between your self-study and Tesla's shadow model?
Suqing: to tell you the truth, Tesla's current model only sees the concept and has not explained the details. from our practice, there are at least a few things, whether you call it the shadow mode or the car end intelligence.
We have two major technologies, one is the RoadcodeRT, mentioned just now, which solves the problem of self-learning and self-composition of the whole traffic static environment, including the AVP mentioned just now is also realized by this.
The other is that we call it DDI,DDI, which may be more like your shadow model, that is, DDI will constantly learn the driving behavior of the car owner, not necessarily taking over. Maybe if the behavior of the car itself is not consistent with that of the car owner, he will grab the behavior of the car owner to do iterations, maybe it is the shadow mode you mentioned.
Media: your pre-visual perception is unique.
Suqing: what is unique?
Media: four cameras, telephoto + wide angle + binocular, rarely seen in mass production cars.
Suqing: yes, because the eyes are more difficult, in fact, we didn't do it, but we just did it.
Media: what problem have you solved?
Suqing: there are a lot of problems with binoculars. To put it simply, it is not easy to make good use of binoculars in terms of algorithms, because the essential problem to be solved by binoculars is depth measurement. However, it is very difficult for depth measurement itself to be relatively stable and can be generalized. Most binoculars can only achieve 20 or 30 meters, and we far exceed this data.
Media: at present, this architecture has three lidars and many cameras. This set of architecture can be done on other models, basically not in terms of the number and type of sensors.
Suqing: pretty much, you'll see it's almost the same in this generation of cars. We usually do a small upgrade every 18 months and keep iterating up.
Media: you just said that autopilot may need millions of cars, and now Tesla has a million.
Suqing: good question. I remember who said a question before that makes a lot of sense. What is big data? Big data's focus is not on the word 'big', but on data quality and completeness. This is the essence of big data. Autopilot is actually very similar. There are two key questions in the data. First, the quality of the data itself. Second, the dimension of the data.
On these two issues, I think there is a big problem with Tesla's data.
What is dimension? Just rely on a few simple visual data collection, this data high precision positioning of nothing, the dimension is very low. It is obvious that the car data dimension of ADS is several orders of magnitude higher than it, and the data dimension is extremely important, and the data dimension represents the degree of information richness and differentiation.
Second, the quality of the data itself. You will find that the data itself is generated by algorithms, and the complexity of your low-order system leads to relatively low quality of the data itself. Tesla is currently in this state. If you want me to guess, Tesla's data has long been saturated and has not improved the ability of the system.
In fact, what we lack in ADS is not data, but the algorithm has a lot of problems to solve, I am absolutely not short of data.
Media: to solve these problems, the first logic is to perceive in place, and the second logic is to predict each other's vehicles in place. Which is more difficult?
Suqing: good question. It was very difficult for us to work on the first day, and then we found it difficult to predict. After the prediction, we found that the regulation and control was difficult, and now the regulation and control is over. When we come back, we find it difficult to perceive and continue to cycle.
What you must ask me to say, in terms of the technical complexity of the industry as a whole, everyone knows that it is difficult to perceive at the beginning. If you ask me, in terms of theoretical and technological maturity, forecasting and regulation are the real problems, which many people may not be aware of.
Media: algorithms mainly rely on neural networks for deep learning, and sometimes there are black boxes in deep learning. Do you think there will be a breakthrough in algorithms in the future?
Suqing: first of all, there is not only a neural network in the autopilot system, but only a part of it. In terms of calculation, it accounts for the absolute majority, but definitely not in terms of code scale. First of all, let's clarify this problem.
Second, I firmly disagree with the idea that AI is a black box. Its calculation mode has changed from scalar calculation or linear calculation of CPU to probability calculation based on linear algebra. It is completely explainable from the point of view of probability, and there is no problem at all.
You can think of it as something like probability, statistics and what was in the past. You can't say that probability and statistics can't be explained. I totally disagree with this view.
On the redundancy of autopilot system
Media: so we rely on lidar for long distances?
Suqing: no, that's not how we divide it. People used to ask the question, is your perception pre-fusion or post-fusion or some Redundancy (redundancy) technology?
First of all, I think the idea that sensors don't have Redundancy is nonsense. Then the post-fusion technology was abandoned by us two years ago, and now we are all pre-fusion technologies.
The feature of pre-fusion is to put all the information together and send it to the NN network for processing. It is not a simple question of which sensor uses which information. You can also simply understand that sensors have an Attention mechanism for each other.
On the other hand, the characteristics of different sensors are different. For example, millimeter wave speed is sensitive, but the measurement is a mess, and the vision is better for semantic measurement; the laser is better for geometric measurement, and it itself merges these together.
Millimeter wave we take the raw data of millimeter wave directly and use its original point cloud.
Media: will it be difficult to get raw data from suppliers?
Suqing: there are two questions. First, most of the Tier1 is not willing to open up the original data to you, but Huawei is bigger, and people are also willing to open it. Second, the raw data of millimeter wave is relatively dirty, which is actually more difficult to deal with. We are now using NN to deal with it.
Media: do binoculars make laser redundant?
Suqing: this thing can not be called redundancy, in fact, different sensors, different performance, advantages and disadvantages have a fluctuation.
Media: a head autopilot company proposed true redundancy, taking radar and LIDAR as a subsystem, pure vision as a subsystem, independent testing, and multiplying the takeover rates of the two subsystems to reduce the required test mileage in a statistical sense.
Suqing: frankly speaking, I guess it was written by their Marketing, definitely not by their research and development, otherwise I would doubt their R & D ability. It is not only your perceptual system that really determines your takeover rate, but also has a lot to do with your regulation and control, even bigger than your perceptual system.
These systems don't have what you call a truly redundant design, right?
Second, you can't handle most of those case, that are difficult to handle with 80 times the number of sensors. I bet you. So the logic of doing statistics with this multiplication algorithm is absurd.
True redundancy is a very Marketing saying, if you want to do a good job in sensing, you should do sensor fusion, not redundancy, which is a serious waste of sensors. Their technical level is definitely not like this.
About ADS's competitors
Media: some multinational companies are still playing the concept of L3, but Huawei insists on continuity optimization. What do you think of this traditional big company going to make a breakthrough in responsibility, while we go to break through two different differences in continuity?
Suqing: in fact, you see, the ideas of everyone in Europe are not exactly the same. I make a personal evaluation, which does not represent the position of the company.
I personally think that among the big three in Europe, the public in BBA is actually relatively forward in thinking, which has something to do with their exploration of autopilot for so many years. The ideas of other families are still in the process of evolution.
In fact, Tesla, I'm sorry, I still have to mention Tesla and Tesla. I think it has taught everyone, including us, and the car factory a lot of things.
When you see the car factory, you will find that what is the essential change of an industry? If you look further ahead, you will see clearly.
To go a little further, we used to be steam engines and electric steam, and then the energy revolution or the power revolution, and then the computer was invented, and then the computer was changing everything. In fact, this is the process in the past 30 or 40 years. The computer is changing everything. The mobile phone was changed last time, and the car was changed this time. This is the view of us and Tesla.
In the traditional car factory, first of all, my base is the car, and now there are some single points of the computer, so I take the car as a foundation, and then I try to embed the computer into it. This is the view of the traditional car factory.
Our views are different, our view is based on computers, cars are computer-controlled peripherals, this is the essence of different views, will lead to different views on everything.
So you will see that traditional car factories use this as an idea to make a lot of small boxes, a function plus a box, a function plus a box, but our view itself is a computer, a big computer, and hang up the car. this is essentially different.
Media: so is this the fundamental reason why Huawei doesn't build cars?
Suqing: if you don't build a car, I think it's a matter of business choice. If you don't build a car, the market will be bigger.
