谷歌的无人驾驶汽车是如何看清路况的

Google's driverless car | Sebastian Thrun

作为一个男孩儿,
As a boy,
我很喜欢汽车。
I loved cars.
在我18岁的时候,
When I turned 18,
我最好的朋友在一场车祸中丧生。
I lost my best friend to a car accident.
就像这样。
Like this.
从那时起我便决定要尽我所能
And then I decided I’d dedicate my life
每年都去
to saving one million people
挽救一百万人的生命。
every year.
目前为止我还没有成功,所以这只是一个进度报告,
Now I haven’t succeeded, so this is just a progress report,
而更主要的是,我会介绍一些关于无人驾驶汽车的事。
but I’m here to tell you a little bit about self-driving cars.
我第一次得知这个概念
I saw the concept first
是在美国国防部高级研究计划局(DARPA)举办的无人驾驶汽车大赛上,
in the DARPA Grand Challenges
在该赛事上,能成功穿越一片沙漠的无人驾驶汽车
where the U.S. government issued a prize
将获得由美国政府颁布的奖项。
to build a self-driving car that could navigate a desert.
尽管当时有一百只参赛队伍,
And even though a hundred teams were there,
仍然没有一辆车能成功到达终点。
these cars went nowhere.
于是我们决定在斯坦福建造一部不同的无人驾驶汽车,
So we decided at Stanford to build a different self-driving car.
包括硬件和软件。
We built the hardware and the software.
我们让它学习我们的驾驶技能,
We made it learn from us,
然后任其穿越沙漠。
and we set it free in the desert.
不可思议的事发生了:
And the unimaginable happened:
它成为DARPA无人驾驶汽车大赛中
it became the first car
第一部回来了的汽车--
to ever return from a DARPA Grand Challenge,
这也为斯坦福赢得了两百万美元的奖金。
winning Stanford 2 million dollars.
但我还没挽救任何生命。
Yet I still hadn’t saved a single life.
自那时起,我们便开始专注于
Since, our work has focused
建造一部能在任何地方
on building driving cars
加州的任何一条街道,
that can drive anywhere by themselves —
自己驾驶的汽车。
any street in California.
我们已经让它成功行驶了14万英里。
We’ve driven 140,000 miles.
通过传感器
Our cars have sensors
我们的汽车可以神奇的看到
by which they magically can see
它周围的一切事物
everything around them
并据此对如何驾驶
and make decisions
做出判断。
about every aspect of driving.
它是一个完美的驾驶机器。
It’s the perfect driving mechanism.
我们乘坐它在城市里行驶
We’ve driven in cities,
像旧金山这样的城市。
like in San Francisco here.
我们也乘坐它在1号高速公路上从旧金山到达洛杉矶。
We’ve driven from San Francisco to Los Angeles on Highway 1.
我们遇到过栏杆,
We’ve encountered joggers,
拥挤的公路堵车,收费站,
busy highways, toll booths,
这些过程中并没有进行人工干预,
and this is without a person in the loop;
完全由汽车自己驾驶。
the car just drives itself.
事实上,我们行驶了14万英里,
In fact, while we drove 140,000 miles,
都没有人注意到这是一部无人驾驶汽车。
people didn’t even notice.
盘山公路,
Mountain roads,
日间和夜晚,
day and night,
甚至包括旧金山的
and even crooked Lombard Street
伦巴底街(九曲花街)。
in San Francisco.
(笑声)
(Laughter)
有时候我们的车也会疯狂一下,
Sometimes our cars get so crazy,
做一些小特技。
they even do little stunts.
(视频)男子:噢,我的天。
(Video) Man: Oh, my God.
什么?
What?
另一男子:它在自己驾驶。
Second Man: It’s driving itself.
塞巴斯蒂安·斯伦:现在我无法让我的朋友哈罗德起死回生,
Sebastian Thrun: Now I can’t get my friend Harold back to life,
但我可以为其他的死者做些什么。
but I can do something for all the people who died.
你是否知道驾驶事故
Do you know that driving accidents
是年轻人死亡的第一大原因?
are the number one cause of death for young people?
你是否注意到几乎所有这些事故
And do you realize that almost all of those
都是由人为错误造成的
are due to human error
而不是机器故障,
and not machine error,
因此我们是否可以让机器来保护我们?
and can therefore be prevented by machines?
你是否意识到
Do you realize
我们能让高速公路的承载量提升
that we could change the capacity of highways
2到3倍
by a factor of two or three
前提是我们不依赖于
if we didn’t rely on human precision
人类在行车道间驾驶的精确性 --
on staying in the lane —
我们通过优化车辆的位置
improve body position
让它们在较窄的行车道上
and therefore drive a little bit closer together
近距离的行驶,
on a little bit narrower lanes,
进而可以消除高速公路拥堵?
and do away with all traffic jams on highways?
你又是否意识到在座的各位,
Do you realize that you, TED users,
平均每天
spend an average
花费52分钟
of 52 minutes per day
在交通上,
in traffic,
在你的日常交通中
wasting your time
浪费时间?
on your daily commute?
你可以重新获得这些时间。
You could regain this time.
单就在美国
This is four billion hours
浪费的时间就高达40亿小时。
wasted in this country alone.
同时被浪费的汽油高达24亿加仑。
And it’s 2.4 billion gallons of gasoline wasted.
现在我憧憬一种新的科技,
Now I think there’s a vision here, a new technology,
它能使不久的未来
and I’m really looking forward to a time
我们的后代回望我们这一代的时候
when generations after us look back at us
会觉得由人来驾驶汽车是多么的荒谬。
and say how ridiculous it was that humans were driving cars.
谢谢。
Thank you.
(掌声)
(Applause)
