A few days ago, Xpeng Motors CEO He Xiaopeng publicly stated in an interview that "Ninety-nine percent of AEB of Friends (Friends) are fake.",this burst point of view instantly attracted the attention of the network.

Subsequently, Yu Chengdong countered He Xiaopeng’s AEB argument in the circle of friends:Experience it quickly, even what AEB is, even the top leaders of car companies have not understood it at all.

Wen Jie and Tucki are both in the first echelon in the field of intelligent driving, and this fight has attracted a large number of people who eat melons. So what exactly is the AEB that Yu Chengdong and He Xiaopeng are arguing about? Let’s talk about it today.

When I watched this video for the first time, I was really worried. I didn’t see an old man until the car stopped. With the Aouita 11, there are more and more cases of automatic obstacle avoidance and extreme car rescue.

1. He Xiaopeng: It is said that 99% of AEB is fake.

Recently, in an exclusive conversation with "No.42 Garage", He Xiaopeng released a lot of materials and made a rather sharp comment on the technology of friends and businessmen.

After the launch of the new M7 in Wenjie, it was completely destroyed, with a large quantity exceeding 80,000 units. The AEB active safety promoted by Yu Chengdong has become the main reason for many people to buy it. You know, it can stop at 90km/h, and there is only one at present, but in He Xiaopeng’s view,This is actually a fraud.

In his reply, he said: first, most people may never touch AEB；;Second, friends talked about AEB. I think 99% of it is fake. It is fake. None of the publicity was officially released by the company. It was all from small videos.

At the same time, it added: our people also asked, its AEB can’t be opened at all, and there are too many cases of wrong braking on the road.

Answering "its propaganda effect is greater than its actual use effect?" , He Xiaopeng said:

At present, when talking about AEB in the industry, we mainly talk about vertical AEB; When it is triggered, its speed should be within 60 kilometers per hour in most cases.If the speed is too high, once you brake by mistake, it will be a great shock to users, which is simply unacceptable.

He Xiaopeng added: I don’t think it’s right to treat customers as guinea pigs. Some enterprises dare to do this, but they will also bite back. I have worked in the automobile industry for several years, but I don’t want to do this, but we will definitely do a better job in AEB.

2. Yu Chengdong retorted that the top leaders of car companies don’t understand AEB.

This view has attracted the attention of Yu Chengdong, the chairman of Huawei Zhixuan Car. After all, the other party named it as fraud, so Yu Chengdong refuted it in the circle of friends, saying"The top leaders of car companies don’t understand AEB".

This is not enough. Yu Chengdong continued to write in the comment area of his circle of friends:

Some people don’t understand what AEB is at all, and tell some people that intelligent driving is nonsense/flicker, almost exactly the same!

Lack of basic understanding of industry technology development and future development!

Some car companies are busy doing intelligent driving all day, and the results of AEB active safety test are very poor. When asked, they know that they have not even done the basic functions of AEB.This surprised me very much! Either let the men fool, or lack the most basic understanding of the development of the automobile industry!

There is no doubt that Yu Chengdong’s response is full of gunpowder, but in combination with He Xiaopeng’s previous remarks, it is indeed time to stand up and say, after all, the more clear the argument is.

3. What is AEB?

So what the hell is AEB?

According to public information,AEB(Autonomous Emergency Braking) is an automatic emergency braking system for automobiles.The distance from the vehicle or obstacle in front is detected by radar, and analyzed by electronic control unit. According to different distances and speeds, whether there is a danger of collision is judged, an alarm is given to the driver, and automatic emergency braking or vehicle deceleration is performed to the maximum extent, so as to reduce the probability of collision with the vehicle or pedestrian in front and avoid accidents.

Simply put, it is to take the initiative to help you step on the brakes to avoid hitting people or other objects.

As one of the active safety functions, AEB has increasingly become the standard of many new cars. At present, the relatively advanced AEB score in the industry is 60 km/h.. That is, when driving at a speed of 60km/h, AEB can take the initiative to stop the car before it hits the object when it detects a stationary object in front.

Yu Chengdong promoted that the AEB active safety of its own Huawei ADS 2.0 advanced intelligent driving can reach 90km/h braking, which is "far ahead".It can effectively avoid most traffic accidents caused by inattention and complex road conditions.

4, use it once to return to the book! Huawei AEB successfully avoided hitting the elderly.

Huawei’s ADS 2.0 advanced smart driver does have related cases, not the M7, but another Aouita 11.

Recently, Aouita CEO Tan Benhong shared a very thrilling case. The owner drives a Aouita 11 on the national highway. Because there are few vehicles, the speed is not slow, and the light on the road is not good.

All of a sudden, this Aouita 11 suddenly started to brake, and gave a thumping sound until the brake stopped.The driver found that an old man dressed in black wanted to cross the road. If the vehicle did not automatically identify and brake urgently, the consequences would be unimaginable.

When the Aouita 11 brake stopped, a Volvo S90 came near the driveway. The driver on it also noticed that the situation was wrong, and the brake light was always on. Then the old man retreated to the road and the two cars drove away.

Tan Benhong said:

When I watched this video for the first time, I was really worried. I didn’t see an old man until the car stopped. With the Aouita 11, there are more and more cases of automatic obstacle avoidance and extreme car rescue.

In fact, there are many feelings. On the one hand, it has strengthened our determination to do intelligent driving.Help everyone step on the brakes and take a direction in the extreme situation of being invisible and too late to improve the safety of travel;

On the other hand, I still want to remind you that the current intelligent driving is only an aid, not a real automatic driving. You should concentrate and be ready to take over at any time.

5, the end

From this point of view, the AEB function is indeed very practical in safe driving, and it can even be said that "use it once to return to the book." After all, if you really succeed in avoiding hitting people, the loss saved may be hundreds of thousands or even hundreds of thousands.

Although there are differences in their understanding of AEB, it is undeniable that AEB has become an indispensable part of intelligent driving in the future.

Yu Chengdong and He Xiaopeng’s "pinching each other from a distance" is actually a microcosm of the increasingly fierce competition in the automobile industry in recent years, especially in the research and development of new energy and intelligent driving. Whoever comes up with really good products can survive under the cruel competition.

　　Reference News Network reported on April 4 that foreign media said that the famous Top 500 ranking shows which countries have the most powerful supercomputers in the world. The United States has kept its position as a powerful computer superpower, with China occupying the forefront, while Europeans without their own technical foundation can only be vassals of the United States.

　　According to the website of Austrian Anti-Party Magazine reported on March 30th, German Konrad Zuse invented the computer in 1937 — — Z1。 He later completed the Z3 in 1941, which was the first programmable computer in the world. The transistor was first invented and patented by Europeans.

　　People may think that the computer industry must be owned by Germany — — At least it is dominated by Europe. After all, the inventor was German — — Europeans. No, that’s not the case. In terms of computer hardware, Europe can be said to be unqualified.

　　According to the report, the performance of supercomputers is expressed in units of floating-point operation speed per second (TFlop/s). The most powerful supercomputer in Europe is Piz Daint of Switzerland, which ranks eighth, with a speed of 7788.9 tflops/s. This computer, which belongs to Swiss National Supercomputing Center, is produced by American Cray Company.

　　The United States is strong

　　According to the report, American computers frequently appear in the top 100, occupying the 3rd, 7th, 12th, 15th, 16th, 19th-21st and many other positions. Since the x86 division of IBM responsible for supercomputers was sold to Lenovo in China in 2014, the current ranking of IBM computers (4th, 6th, 14th, 54th and 68th) is shared by China and the United States.

　　The United States occupies 31 places in the top 100. Because the rankings of other countries that use American processors are not counted, this figure does not reflect the real strength of the American computer industry (specifically, the chip giant Intel).

　　According to reports, most supercomputers in Japan use Fujitsu processors. So is Japan very independent? Not exactly. Fujitsu is an R&D and production partner of Intel. Therefore, Intel’s genes also promoted the development of Fujitsu processors.

　　According to the report, Europeans have no ability to succeed on their own in supercomputer technology. The most powerful supercomputer in Europe must be purchased — — Buy from America. Apart from Switzerland, Finland, Sweden, Britain and Germany are all customers of Cray. American computer companies do well in Europe. HP’s customers include Poland, France and Czech Republic.

　　According to the report, there are also many computers in China in Europe. Lenovo and Huawei are famous Chinese brands in Europe. Italy and Germany are Lenovo’s customers. Lenovo has bought part of IBM’s computer business little by little in recent years. Therefore, in the past, the customers of "Blue Giant" became Lenovo’s customers. With the help of China — In the framework of cooperation between Central and Eastern Europe, Poland has become a close partner of China people, especially in the computer field. Poland’s supercomputers occupy the 48th, 90th and 92nd places in the top 100. The computer ranked 48th was purchased from Hewlett-Packard in the United States, but now it attaches great importance to cooperation with the United States and China.

　　China processor is far ahead.

　　The report said that in terms of supercomputers, China has not caught up with the United States — — But surpassed the United States. China occupies the 1st, 2nd, 42nd, 67th, 74th, 77th, 78th, 86th, 91st and 96th positions in the top 100 respectively. Tianhe-2, ranked second, still uses Xeon processors from the United States. Now this is a thing of the past.

　　During this period, China people developed their own processors — — The Shenwei processor makes Intel’s Xeon look old. Top 500 ranked first in China Shenwei Taihu Lake Light, and its peak speed reached 125,435.9 tflops/s. The third-ranked American Cray Company’s supercomputer using AMD Opteron processor has a peak speed of "only" 27,112.5 tflops/s. This is roughly only 22% of the light of Taihu Lake in China.

　　According to the report, the best supercomputer in the European Union is the Mistal in Hamburg (using American processors), which ranks 33rd, with a speed of 3,147.8 tflops/s, only 2.5% of the light of Taihu Lake. The most powerful computers in the European Union can only achieve 2.5% of the performance of China supercomputers by using American components.

　　Now can you understand why Trump wants to make America great again? He is right to say so. In the field of computers, the technology of the United States is many light years ahead of that of Europe, but it is only ahead of Europeans, not China.

　　Specifically, a giant battle, a battle between the United States and China, and a processor war between American chip giants AMD and Intel and Shenwei of China Jiangnan Computing Technology Research Institute have begun.

　　According to the report, with the launch of processors such as Huawei Kunlun and FusionServer, another China company is also shaking the position of AMD and Intel. It should not be forgotten that Huawei and Intel have a technical cooperation relationship. With Intel’s genes, Huawei is now preparing to step out of Intel’s shadow and bathe in the sunshine of the computer industry independently.

　　Europe’s achievements in the computer field are few and far between. Think about it, only such achievements can be achieved with American processors. In the field of computers, European technology is virtually the same as non-existence. This is a shame for Germany and Europe: they waste the advantages and great legacy created by people like Chuze.

　　On August 26th, the second China International Intelligent Industry Expo officially kicked off in Chongqing, and the mountain city once again set off a wave of intelligence. With the theme of "Empowering the economy and adding color to life", this year’s Zhibo Fair invited Nobel Prize winners, Turing Prize winners, leaders of the world’s top 500 companies and leading enterprises in the global big data intelligent industry to attend.

　　Following the gathering of the last Zhibo Fair, Ma Yun, Ma Huateng and Li Yanhong, three Internet technology industry tycoons, will once again join hands to attend the fair, and put forward their views and imagination on the intelligent industry around the topics of "enterprise innovation", "industrial competition" and "artificial intelligence" at this year’s Zhibo Fair.

　　The speeches of the three heads are full of personality. Ma Yun, who pays attention to sustainability, attaches great importance to the cultivation of the development source of innovative technology. In his speech, he proposed that "technology is developed, not regulated"; Ma Huateng, who is leading Tencent’s transformation, continues to speak for the industrial Internet, trying to attract more partners to make new "fist products" together; Li yanhong, a technical background, values AI landing, and his core views revolve around practicality and independent intellectual property rights.

　　Jack Ma

　　In the future, human beings will live by data.

　　Ma Yun is one of the three entrepreneurs who has invested the most in education. In sharing, his views also revolve around the universal and sustainable development of people, cities and even technology, which is consistent with the concept of teaching without distinction and learning with each other in educational thought.

　　Ma Yun’s speech started with social progress. He compared the difference between Chongqing and Silicon Valley, and thought that holding the Zhibo Fair in the southwest of China represented social progress. Regarding how the society will progress and how the city will develop in the future, Ma Yun borrowed from the residents in Guizhou mountainous areas to become a data annotator through data annotation training, creating a large number of employment cases, and proposed that in the future, human beings will live by data and find a place to communicate with data.

　　In the current digital age, technology is playing a more beneficial and convenient positive role in regional development and personal growth. Ma Yun said that what leads the future is the wisdom of human beings behind intelligence, and suggested that "in the era of wisdom, technology and equipment should be spent on human progress and human feelings".

　　Talking about macro-innovation, Ma Yun suggested that China has the opportunity to become a country on the Internet, but in comparison, there are not many enterprises like BAT, but fewer, and China should develop dozens of such enterprises. "We should not be afraid that innovative enterprises will become giants, but should worry that giants will not innovate."

　　Ma Yun believes that the next 30 years will be an era of intelligence, and the modern service industry will become the dominant employment, the essence of which is the development of finance. Ma Yun talked about the three relationships of "intelligence+":in the era of intelligence, intelligent policies are needed, and all intelligent businesses must bear corresponding responsibilities. No one can be big without taking responsibility. He expects big enterprises and big innovations to contribute to solving social problems and future problems.

　　Pony Ma

　　Industrial competition has entered the era of "doubles"

　　After a major organizational restructuring, Tencent has focused its business on developing the industrial Internet for a year. Ma Huateng’s speech at the Zhibo Fair mainly focused on the industrial structure, and the call for "doubles" released the signal that Tencent wanted to form an alliance with friends.

　　Ma Huateng said that the main field of industrial competition is gradually changing from "singles" PK to "doubles" competition. The competition of physical industries is no longer a solo struggle, and various physical industries are combining with the information industry to form new partners to participate in the competition.

　　Recently, Tencent has "rooted in the consumer Internet and embraced the industrial Internet", hoping to become an assistant for digital transformation and upgrading in all walks of life. Taking automobiles as an example, Ma Huateng mentioned that the automobile industry is facing a great change that has never happened in a century. The application of 5G technology, the landing of artificial intelligence, the replacement of new energy, and the governance of smart cities are promoting cross-border cooperation, especially the integration and innovation of information industry and automobile industry, and building a new car networking ecosystem.

　　Ma Huateng believes that in the past few decades, the rapid development of China’s economy and industry mainly benefited from the extension expansion. In the next few decades, China must exert its innovation potential to achieve high-quality development. Therefore, today’s China industry needs more fighting spirit. "In the face of economic transformation and industrial upgrading, we need to constantly stimulate the innovation potential and create more fist products."

　　Li yanhong

　　Artificial intelligence can no longer "show off skills"

　　The in-depth layout of artificial intelligence has always been the core strength of Baidu. "Artificial intelligence no longer pays attention to coolness, but pays attention to solid promotion and implementation." At the Zhibo Fair, Li Yanhong shared three suggestions on promoting and landing artificial intelligence based on the observation of the application and development of artificial intelligence technology.

　　First, we should pay attention to safety and efficiency. Li Yanhong pointed out that from the perspective of safety and cost, the low-speed L4 in the driverless field will be realized before the high-speed L3. The reason why Baidu slowed down the speed is to ensure safety.

　　Second, I hope to speed up the construction of infrastructure. Li Yanhong, who once worked on Wall Street, has a personal experience of Sino-US competition in science, technology and commerce. Focusing on the different development directions in the field of autonomous driving, he pointed out that China and the United States actually have considerable competition. The United States places more emphasis on bicycle intelligence, while China has advantages in infrastructure, and can add many devices on the roadside to improve safety and efficiency.

　　The third is to make full use of open source and open platform. Li Yanhong said that China’s open source platform started relatively late, but it played a vital role in the development of artificial intelligence. He believes that the industry should fully realize that open source does not mean that everything is free, but self-controllable, and many open source things still need to be in the hands of others.
