The autonomous driving classification is developed by the National Highway Safety Administration (NHTSA) and the Society of Motor Vehicle Engineers (SAE), and their standards enjoy high authority and fairness around the world.

There are five levels of specific definition of autonomous driving.

Level 0 (no automation): The car is fully operated by a human driver, assisted by a warning and protection system while driving.

Level 1 (Driving Support): Provides driving support for one operation of the pay-off reel and acceleration and deceleration through the driving environment, and the other driving maneuvers are operated by a human driver.

Level 2 (partially automated): The driving environment provides driving support for various operations such as steering wheel and acceleration and deceleration, and all other driving maneuvers are performed by a human driver.

Level 3 (Conditional Automation): All driving operations are performed by an unmanned driving system. At the request of the system, the human driver provides an appropriate response

Level 4 (highly automated): All driving operations are performed by an unmanned system. Depending on the system request, the human driver does not necessarily need to respond to all system requests, limit road and environmental conditions, etc.

Level 5 (fully automated): All driving operations are performed by an unmanned driving system. Human motorists take over where possible. Drive in all road and environmental conditions.

We are now familiar with car functions such as the common cruise control belongs to level 2 automatic driving, to reach level 3 automatic driving can already complete most of the road conditions of automatic driving, but also need people to participate in some special situations of manual intervention, now the vast majority of autonomous driving technology research and development companies are in this stage, such as Google's autonomous driving technology, this level of driving technology is also called semi-automatic driving, in the subway, railway and other fields have long been realized.

Then to level 4, that is, a high degree of automation can be called automatic driving, this level of automatic driving in the support of high-precision maps has been fully realized automatic driving, the whole process does not require manual intervention, on the road can already be on the road, only in some partial areas, or there is no accurate map on the road to need manual intervention, simply put, there is no problem at all in big cities, only to the township, or remote areas, there is no accurate map to support the area will need manual intervention。

And the ultimate level of automatic driving is level 5, this level reduces the dependence on accurate maps, relying on the real-time feedback of the vehicle on road conditions, can adapt to all roads, one of the biggest technical barriers at this level is the real-time recognition of images, and this is also one of the reasons why Qiandu Group is willing to spend a lot of money to acquire rice engines, of course, in order to achieve this level of automatic driving is not only image recognition, this technical barrier also has other barriers, such as radar, sensor data processing, it can be said that autonomous driving technology is a collection of various fields。

Mr. Liu saw Yang Qing's surprised expression and said: "Mr. Yang, you know that the major shareholder of our dolphin is Qiandu Group, so you know more about Qiandu, in the past two years, Qiandu Group has pressed all its technical strength on automatic driving, and the amount of money invested every year is massive. ”

Yang Qing nodded and said: "That's right, unmanned driving technology can indeed make Qiandu Group stabilize the status of the three giants." ”

Mr. Liu said with a smile: "However, although Qiandu Group has obtained the permission to go on the road, there is still a lot of resistance to popularization!"

Yang Qing said suspiciously: "Do you mean the driver?"

Mr. Liu nodded and said: "That's right, now the first object of cooperation with Qiandu Group's driverless technology is not a private car, but a bus, do you know how many bus drivers there are in the country?" There are more than 30,000 cars in Kyoto alone, 3 staff members per car, plus other personnel, this is the job bowl of nearly 100,000 people, not to mention the whole country, which is related to the livelihood of millions of people. And what's even more serious is that these bus drivers are generally local people, and once they make trouble, the consequences are unimaginable!"

Yang Qing heard this: "This is a thunder, Qiandu can't help but step on it." ”

Mr. Liu: "Well, if Qiandu Group wants to popularize unmanned technology, it must enter the field of buses, only if it has a firm foothold on the bus can it be quickly popularized to private cars, many people do not trust this new technology, this is no more than other things, once the car is out of control, it is life, if there is no government to endorse, there are not many people who dare to try the automatic driving of private cars." ”

Yang Qing agreed: "Yes, without the endorsement of the government, unmanned driving cannot be popularized, now that Qiandu can get a permit on the road, it seems that no matter what the government departments have made relevant plans, now they are waiting for the drivers to make trouble!"

Mr. Liu said: "The progress of technology will inevitably lead to the elimination of some people, which is unavoidable, just like Mr. Yang's fugue, which makes us very uncomfortable!"

"Hahaha" Yang Qing laughed and said: "Mr. Liu said this against his will, this cooperation with your dolphin network has taken a big advantage!"

Mr. Liu also smiled: "Mr. Yang's advantage is really not easy to take advantage of, I don't know how to die even if I die one day!"

"Mr. Liu is too careful, can I still play the trick of swallowing the elephant?" Yang Qing said with a smile.

"If you want me to say that Mr. Yang's company is not a snake now, it is completely a potential underwater predator, choose people to eat!" Mr. Liu said with a smile.

Yang Qing smiled when he heard this: "The predator is the predator, I will be Mr. Liu, this is praising me!"

After saying this, Yang Qing immediately said: "Speaking of predators, the Penguin Group is the real predator, and it has not fallen after such a big turmoil, so it has to be awe-inspiring?"

Mr. Liu nodded and said: "Although the privacy incident has greatly damaged the vitality of the penguin, but the prestige is still the biggest overlord in the social field, and the jingle of the big thief group began to be weak after gaining 200 million users. ”

"The strength of the thief group is in e-commerce, how can he use blood to fight with penguins, besides, this is not only a matter of money, I estimate that the relevant departments will also interfere, otherwise how could the thief group suddenly stop fighting, which is inconsistent with Ma Dabai's past practice" Yang Qing analyzed.

Mr. Liu said: "There are reasons for this, but the most important thing is that Penguin's products are really good, especially the current small program, which has united a large number of entrepreneurs, which feeds I don't know how many startups, and now Weixin has formed a huge ecosystem, involving all aspects of society, once Weixin falls, the impact will be too great." ”

Yang Qing agreed: "That's right, prestige is no longer just a social software, now it has become a public facility, many government functions have been grafted to prestige, and prestige has been deeply rooted in the hearts of the people for so many years, and it is indeed difficult to shake prestige with a privacy issue." ”

“……”

Yang Qing and Mr. Liu chatted about the giants on the Internet for an afternoon, and before they knew it, it was afternoon.

Yang Qing looked at the time and said: "I recently found a small restaurant near the company, although the store is small, but the dishes are very distinctive, especially the special dish spicy chicken, the taste is really good, do you want to try it?"

"Spicy chicken, then I have to taste it?" Mr. Liu responded.

"Then let's go over here?" Yang Qing asked.

"Okay!" Mr. Liu agreed.
