China has moved in recent months to allow autonomous car tests on city roads, and has said it hopes that smart cars will make up half of new cars on the road by 2020. That’s a goal that, for now, requires US and German technology.
Laser-radar sensor technology, or lidar, is what allows an autonomous car to “see” what’s around it, but Chinese domestic lidar manufacturers are still struggling to match US technology, according to Chinese newspaper Science Daily(link in Chinese) on Tuesday (May 9). As a result, many self-driving car companies need to import foreign lidars, and many of them rely on a single company: California-based Velodyne.
Baidu, China’s search giant, used Velodnye’s lidar to conduct a road test in China in early 2016, and is also an investor in the company. Pony.ai, a self-driving startup in the southern city of Guangzhou, is also using Velodyne’s lidar to test cars. Velodyne has previously said that 85% of participants in a 2015 autonomous vehicle competition in China were using its lidars.
Usually mounted on top of the car, the lidar continuously sends out laser beams. By measuring the time it takes the light to bounce back from nearby objects, it produces a 360-degree real-time map, which the car’s computer uses to make predictions and decisions. Compared to radar, lidar’s laser vision is better at capturing arms and legs, which makes it better at helping the car handle pedestrians. Every serious player in the self-driving race sees laser vision as an indispensable ingredient for a fully autonomous car, noted technology news blog Wired. (Elon Musk, though, has argued that lidar isn’t necessary, and is instead banking on cameras.)
China has long said it want to rely more on indigenous technology, and as tensions with the US over tech ratchet up, it’s putting more money into that. Right now China now only make lidars capable of emitting 40 laser beams—far from the 128 laser beams rolled out by Velodyne late last year. More beams require chips with higher processing power to better project and receive signals, and domestic lidar makers also often have to source these from overseas.
A company spokesperson for Chinese lidar maker RoboSense told Quartz that the Shenzhen-based firm turns for part of its chip supplies to Germany, as well as other countries. The company says it has been providing lidars emitting 16 to 32 laser beams to self-driving firms in China, but didn’t provide names.
The high cost of manufacturing top-end lidars, and the relatively long time it takes to test the technology to meet safety regulations, are another obstacle. They’re why top lidars are still pretty expensive, although Velodyne cut its 16-beam lidar, its most popular sensor, to $4,000 this year. Experts say prices need to be a tenth of that for widespread adoption of self-driving cars.
Still, figuring out how to mass produce a high-end tech product cheaply is a problem that China’s really good at cracking. And as China’s pushes local manufacture and sourcing, it might not be surprising to see lidar become less of a niche industry in the future—perhaps with a little bit more help

Magnificent goods from you, man. I have keep in mind your stuff prior to and
ReplyDeleteyou're simply too fantastic. I really like what you've received here, certainly like what you're stating and the best way through which you say it.
You are making it entertaining and you continue to take care of
to keep it smart. I can't wait to learn far more from you.
That is really a great website.
Today, I went to the beachfront with my children. I found a
ReplyDeletesea shell and gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear." She placed
the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear.
She never wants to go back! LoL I know this is completely off topic
but I had to tell someone!
Pretty section of content. I just stumbled upon your site and in accession capital
ReplyDeleteto assert that I acquire actually enjoyed account your blog posts.
Any way I will be subscribing to your augment and even I achievement you access consistently rapidly.
It's an amazing post in support of all the online people; they will obtain benefit from it I am sure.
ReplyDeleteGreate pieces. Keep posting such kind of information on your site.
ReplyDeleteIm really impressed by it.
Hey there, You've performed an incredible job. I'll certainly digg it and individually suggest to my friends.
I'm sure they'll be benefited from this web site.
I used to be able to find good info from your blog articles.
ReplyDeleteHi there mates, how is the whole thing, and what you would
ReplyDeletelike to say concerning this article, in my view its really awesome
for me.
For him, a single rod would far more than suffice.
ReplyDeleteWhen someone writes an post he/she maintains the plan of a
ReplyDeleteuser in his/her brain that how a user can be aware of it.
So that's why this article is great. Thanks!
