您正在收看的是冷流科技
You are watching ColdFusion TV

大家好 欢迎再次收看ColdFusion视频栏目
Hi,welcome to another ColdFusion video.
在以往的视频中
in previous videos
我们已经看到了特斯拉是如何撼动汽车工业的
we’ve looked at how Tesla shaking up the automotive industry
但最近 他们正着手做一件更具影响力的事
but recently they’re taking things a whole level further
正如诸位可能听说的一样
as many of you would have heard
特斯拉已经为其2014年后期推出的Model S型轿车
Tesla has released a software update for their
和Model X系列轿车
late 2014 Model S
进行了软件更新
and Model X series cars
我知道
I know
这听起来也不是啥大事
it doesn’t sound like much for a big deal
但实际上 这其影响正慢慢显露出来
but it’s actually starting to turn into one
真正有趣的是
the thing that’s interesting
同时也是本期节目主要关注的
and the main focus of this video is that
是轿车真正学会自动行驶
is that the car actually learns how to drive
这是汽车产业的一大突破
pretty much a breakthrough in the automotive industry
我们将探讨这项突破的细节
all get to the details of that breakthrough
稍安勿躁
in a second
但作为开场
but to get started
咱们看看这套系统的实际表现
let’s see the system in action
着实令人印象深刻
that’s pretty impressive
你能及时做出反应吗?
would you have reacted in time
咱们再看一遍
it’s just take another look at that
以这样的速度
at those speeds
如果司机的确已经分心了
if the driver had at all been distracted
结果可能非常不一样
the result could be very different
那么更新的软件中包括什么呢?
so what does this new update include
这种车可以
the car can
几乎无所不能
do almost anything
因此 我们能够
so we’re able to

uh
显而易见 可以在高速公路上沿车道行驶
obviously do lane- keeping on freeways
还能 呃…
do uh…
自动巡航控制
automotive cruise control
呃…
uh….
自主紧急制动
active emergency braking
自动停车
itself-park
因此 你的车可以自动平行泊车 自动入库
so you’ll be automatically parallel parking automatically going to garage
你回到家 就能
you get home actually be able to just
直接从车上下来
set out of the car
车就能自动泊入车库 包括
and have it park itself in your garage including
能自动打开车库门
it’ll open the door
会自主泊车入位
and it will go and park itself
下一步呢
going the step further
你将要能召唤你的轿车
you will be able to summon the car
只要是在你自己家
if you’re on private property
因为你必须在自己的房子里
’cause you have to be in private property though

uh
实际上 你可以召唤你的轿车 它会达到你所在的位置
you can actually some of the cardinal the car will come to where you are
它使用的超声波传感器 就像
it’ll use the ultrasonic sensors kind of like a
昆虫的触角一样
insect antenna
它会慢慢开到你的位置 然后停下来 等你上车出发
slowly make its way to you and then it stop and be ready to go
甚至也有还可能比这再进一步
it can actually go even a step beyond that which is
如果你打开日程安排功能
if your calendar turned on
它可以
it’ll
在预订地点等你
meet you here
就这样
ok
因此
so
轿车如何学习?
how does the car learn
当然是跟人类学的
it learns from humans of course
这真的是项重大突破
this is the real breakthrough
在最近的几次媒体招待会中
in the recent press conference
马斯克将每一位Model S型车主
Musk prefer to each Model S owner as
都称为专业教练 他们为整体的人工智能网络增添了信息
an expert trainer that feeds a collective AI network
方法就是单纯地用自动驾驶模式开车而已
by simply just driving the vehicle on autopilot
换句话说
in other words
每名特斯拉车主 在自动巡航模式下驾驶汽车时
each Tesla driver trains their car when they drive on autopilot mode
都在训练他们的汽车
by doing this
他们强化了的自己想要的汽车行驶习惯
they reinforce one- two driving behaviors from the car
弱化了不便于使用的行驶习惯
and discourage unone- two driving behavior
但有趣的是
but the interesting thing is
每一辆特斯拉轿车只都是这个集群的一部分
all Teslas are part of the fleet
因此 当一辆车学会了
so when one car learns
它就通过网络教会所有特斯拉轿车
it teaches that to all Teslas over network
因此 他们全都一起学习
so they all learn together
它基本上可称为特斯拉
it’s basically a hive mind
集群思维
of Teslas
它几乎可被当做 机械学习和自动化的完美结合
it almost seems like the perfect combination of machine learning and autonomy
炫酷到不行
really cool stuff
既然有成千上万人在训练特斯拉轿车
since there are tens of thousands of humans training the Teslas
所有轿车都在一起学习
and all the Teslas learn together
这就制造了大量具有指导作用的数据
that makes for a lot of instructional data
因此 所有的特斯拉轿车理应擅长行驶
so all the Teslas should get very good at driving
而且是在短时间内学会
very quickly
埃隆表示 这个系统应该每天都在提高
Elon says that the system should improve every day
途径是升级行驶算法
by updating the driving algorithm
他继续表示 Model S型车主每日可以新添加约一百万每英里的数据
he goes on to say that Model S owners could add approximately 1 million miles of new data every day
有趣的是
it’s interesting to note
这次媒体见面会结束的几星期后
that just a few weeks after the release
Model S型车主在不少网站上
Model S owners on websites
比如 特斯拉汽车公司俱乐部
such as the Tesla Motors club
已经开始描述 自动驾驶是如何
already describing how autopilot is
自我改进的
improving by itself
下面是一个例子
here’s one example
一个小伙在崎岖的道路上对自动驾驶进行测试
one guy tested autopilot on roads with aggressive curves
特斯拉并不推荐这种做法
which Tesla does not recommend
但最后证明了
but still as it turns out
自动驾驶系统正在学习如何处理大角度转弯的行驶
the system is learning how to handle sharp curves
速度还相当快
pretty fast
第一次有意识使用此功能的用户说 首次驾驶该车以全速通过弯道时
the user with the main common sign states that the first time use the car to take a curve full speed
轿车无法呆在行车道上 而且自动驾驶系统通知驾驶员立刻掌控车辆
the car didn’t stay in the lane and issued the take controller immediately alert
经过几次转弯行驶后
after a few times more on this curve
方向盘自主产生了压力
with firm pressure on the steering wheel
轿车学会了先减速 然后转弯
the car start to learn to slow down first and then take the corner
如今 该车在转大弯上已经没有问题了
and today the car has no issue taking the curve
它确实在学习
it’s definitely learning
我会在视频下面的内容描述中 给出该论坛的链接
I’ll leave a link to the forum in the description below
这样你能亲眼看看 还能看到
so you can take a look for yourself and what reactions are
那些爱车开始学习驾驶的车主作何反应
of the drivers whose cars are starting to learn how to drive
真的是很神奇
it’s pretty fascinating stuff
而且 负责任地说
and it’s safe to say
曾经如科幻小说般的场景
what was once thought to be science fiction
在今天得以实现
is now reality today
好的 咱们继续扒
already let’s go deeper
这套系统如何运作呢
how exactly does this work
根据埃隆的说法
according to Elon
自动驾驶有四个基础
there are four pillars for autonomous driving
第一个是远距离雷达系统
the first one is a long distance radar system
这种雷达基本能穿透所有事物
that can see through virtually anything
包括沙子
this means sand

snow
灰尘
dust
或是其他人眼看不清楚的东西
and other things that the human eye might not be able to see through
第二项技术是
the second enabling technology
装有图像识别软件的摄像机
is cameras with image recognition software
第三
the third
超声波传感器
ultrasonic sensors
第四
and fourth
是卫星图像
is satellite imagery
具备显示实时交通状况的功能
with real- time traffic
这些系统综合起来后
when these systems are all integrated
你会得到一个非常有力的
you get a very robust
整体系统
overall system
几乎可以被当成是数字化延伸开来的
that almost acts like a digital extended safety cushion of
技术安全垫
technology
且专为你的轿车而设计
for your car
那么开起来感觉如何
so how is it like to drive
这是来自
here’s some insight
美国Cent网的一些评测
courtesy of Cnet
现在 我们要试试变道 我的盲点中目前有辆车
so we’re going to try lane- change here there’s a car in my blind spot right now
所以 车不会变道
so it won’t do it
那辆车走了
the car is gone
咱们看看现在它是不是要变道
let’s see if it’ll change now
好了 正如你看到的
here we go as you can see
我没有控制方向盘 车自己变道了
even though change lanes completely hands- off
现在我的手完全离开了方向盘
right now I’m gonna take me hands completely off the wheel
脚也离开刹车油门了
and my feet off the pedals as well
你可以看到车是自动行驶的
and you can see the car is moving along on its own
我们的前面 有一辆正在减速的沃尔沃
there’s a Volvo in front of us is slowing down
系统已经辨认出它了 仪表板上显示出一辆蓝色的汽车
and car is recognizes that there’s a blue car here on the dashboard
新版本的软件改善了七个方面
which has been improved to the new seven point of software
所以基本上 我的车跟随着前车的一举一动 它慢下来 我们就慢下来 它加速
and it basically is following the moves of that car hindering so as it slows down we will slow down and as it speeds up
我们也会加速
we will too
好了 在结束本期节目前
ok before we wrap up the video
让我们听听埃隆关于这项新科技的观点
let’s hear a bit from Elon about the new technology
以下是他关于法律影响的内容
this is him on the subject of. legal implications
咱们谈谈自动驾驶 有司机会说 嗨
it’s a bit of it on autopilot and the driver says hey
你知道吗
you know
自动驾驶该为我变道的 结果却撞上障碍物了
this was supposed to change lanes for me and instead it this barrier
我想 你晓得吧 让特斯拉为此负责
I want,you know, I want Tesla to be responsible for this
是的 我觉得我们会
yeah, I think we’re gonna be quite
与客户明确
clear with customers that
这个责任
the responsibility
始终由驾驶人承担
remains with the driver
呃…
uh..
我们从没主张 我们的轿车有能力
we are not asserting that the car is capable of driving
在没有驾驶人监控的情况下行驶
in the absence of driver oversight

uh.
就是这样的
that will be the case
在将来也许
in somewhat the future like maybe
距今5、6年后
5 or 6 years from now
我觉得我们可以实现
I think we’ll be able to achieve
真正的自动驾驶
a true autonomous driving
到时候你就可以
where you can literally
坐上轿车
get in the car
一觉醒来就能到达目的地了
go to sleep and wake of the destination
可能达成这个愿景还要十年
probably just got there was more like 10 years
但根据我在这个过程中 所见到的改进速度
but basing the rate of improvement that I’m seeing in the progress
我认为 我们可能在未来5、6年达成目标
we’re making I think we’ll probably do in 5-6 years
同时 完全自动驾驶的标准 要远远高于满足个人的需要
and it’s the standard for fully autonomous driving to be much greater than for a person
如果标准仅仅相同 是远远不够的
it’s just equivalent that would be enough
但要达成这个目标 你就必须拥有
but in order to do that you have to have
完整的冗余系统 每个系统
fully redundant systems everything is going to
都有冗余 这样单独的系统崩溃才不会造成事故
be presented to that anyone system breaking just not result in an accident
你还必须要
and you also have to prove
通过上百万英里的行驶
that out over
来证明可行性
millions of miles’ driving
我知道看官中可能有人在想
so I know what a few of you are thinking
系统被黑了怎么办?
what about hacking
它很像
it’s a lot like a
一部手机
like a cell phone
或是一个笔记本电脑
or a laptop
呃…你…
uh… you ..
你必须重点保证系统的可靠性
you focus on making sure that they can’t account or
保证难以对系统进行
that is very different for them to be a kind of
全面的
system- wide
黑客攻击
hack
呃…那么…
uh… so…
我们为此下了很大功夫
we put a lot of evidence that we
我们邀请第三方团队对系统进行黑客攻击
have third parties try to attack it

uh.
在轿车某些部分
and in certain parts of the
在基本功能层面
the car at the very fundamental level
比如驱动装置控制器或是转向器
like the drive unit controller or the steering controller
我们增加了额外的安全措施
have an additional level of security
你也不用担心出现”天网”那样的场景
and you don’t have to worry about a Skynet scenario
因为埃隆自己
because Elon himself
对人工智能非常担忧
is very weary of AI
你自己投资了像
do you yourself have invested in some
Deep Mind和Icarious这样的人工智能公司吗?
AI companies like Deep Mind and Icarious?
是的
yeah
为什么
why
我投资是为了监视人工智能的发展
I invested in those companies keep an eye on it
我想看看人工智能技术是如何发展的
I want to see how artificial intelligence was developing
所以 从这些内容能得出什么结论呢
ok so what is the conclusion to draw from this
有人认为 特拉斯被极大地高估了
a lot of people say Tesla is drastically overvalued
随着新技术泡沫的破灭消失 特斯拉也会消亡
and it’ll vanish with the bursting of the new tech bubble
虽然 事实上我们正处于科技泡沫的时代
although it’s true that we’re in the tech bubble
我以为 特拉斯向我们展示的东西 是无法立刻衡量的
I think Tesla was showing us something that cannot be instantly measured
就是创新
innovation
他们确实为已经有百年历史的汽车工业
they really are showing a whole new way
展示了一条新的道路
for an entire century old industry
我得说 虽然创新很难衡量
and I’d say even though it’s not easily measured
但这是非常有价值的
that is very valuable
正如诺贝尔经济学家罗伯特•席勒所言
as Nobel economist Robert Shiller puts it
引用
quote
“在我们的经济生活中 技术带来了最重大的变化
“technology has made the biggest changes in our economy
我们应该开始以不同的眼光 审视国内生产总值(GDP)和生产力的数据
we should start to take a look at GDP and productivity numbers differently
因为它们没有计算或者捕捉到
because they are not estimating or capturing the impact of new
新科技的影响”
technology”
引用完
end quote
为正确认识上述观点
and just to put that into perspective
特拉斯全体 正在相关市场里奋力前进
Tesla as a whole is dying to progress in their relevant markets
例如
for example
我刚看了看特拉斯的股东大会
I just had a look at Tesla shareholder meeting
我惊讶地发现
and I’m surprised to find out that
特拉斯现在
Tesla is now the number one
北美地区高端豪华轿车
seller of high- end premium sedans
销售量排名第一
in North America
不仅如此 2015年特拉斯在瑞士的销量
not only this but for 2015 the Tesla Model S in Switzerland
超过了奔驰S系列
has sold more than the Mercedes S- class
宝马6系列
BMW 6 series
还有奥迪A7系列
and Audi A7
在瑞士的全部销量
combined
此外 你现在去美国任何地方旅行
in additional to this you can now travel anywhere in the US
都可以使用超级充电器
using the super charges
总而言之 这是特拉斯团队的一大壮举
so all in all it’s a great job done by the Tesla team
他们多次展示了 为什么电动汽车
they’ve repeatedly shown how the electric car
代表了未来
is the future and
同时 他们通过辛勤工作 使道路变得更加安全 也一再证实了这一点
their latest efforts do that by making the road a safer place
我认为这是一件很好的事情
and I think that’s a good thing
