Yu Chengdong responded! So, who the hell doesn't understand AEB?

There was a big incident in the car circle, and Yu Chengdong's circle of friends rarely replied to He Xiaopeng.

Here's the thing:

A few days ago, He Xiaopeng was interviewed by Garage 42, Diss friends:

To put it simply, He Xiaopeng thinks that Huawei AEB is so powerful, it should be fake.

Here is a very good explanation of what AEB is, AEB stands for Autonomous Emergency Braking, that is, the automatic emergency braking system of automobiles.

Anyone who drives should have experienced it, that is, in case of emergency, the car will automatically brake.

Yu Chengdong's response has two main points:

1, He Xiaopeng doesn't understand AEB, just like Wang Chuanfu doesn't understand intelligent driving;

2. AEB with the blessing of intelligent driving is more powerful than traditional AEB, which is why Huawei AEB is so powerful.

Who is right and who is wrong, everyone will discuss rationally in the comment area.

Ask the worldM5 intelligent driving version,Lao Fox has experienced it in depth,It triggers AEB quite a lot of times,It's just that the experience of sitting on it is not very good,It's really okay to brake it。

And judging from the tests of these institutions, the M5 intelligent driving version of the AEB is indeed far ahead. We'll talk about that later.

Then why, why did Yu Chengdong suddenly point the finger at He Xiaopeng, let's get to the core of this controversy.

Yu Chengdong finally couldn't bear it?

The large order exceeded 80,000 units, and Wenjie returned to the monthly sales club of 10,000 units.

However, it has also been questioned by a lot.

First of all, in the press release of the "1024 Xpeng Technology Day", "Unlike other brands, the first phase of Xpeng's NCA without map capability will officially open the public beta to users on the evening of October 24, and will be fully opened in the near future."

Suspected of connotation, Yu Chengdong said when the new M7 was launched: The NCA function in the urban area will be opened nationwide in December this year.

In contrast, Xpeng did give a specific time, the first phase of opening 20 cities, increasing to 50 cities within the year, and achieving high-end intelligent driving coverage in all regions of the country in 2024.

According to the coverage area, the rhythm of the action of the question boundary should be faster. With the broad charm of words, Xiaopeng may want to compete for the title of "King of China's Intelligent Driving".

This time, Yu Chengdong rarely did not respond.

And a few days ago, He Xiaopeng said in an interview in garage 42:

Most people may have never touched AEB, friends talked about AEB, I think 99% is fake, it is fake, there are too many cases of accidentally stepping on the brakes on the road.

once again stepped on a wave of questions and Yu Chengdong.

And this time I couldn't bear it, Yu Chengdong sent 4 replies in a row, directly complaining about He Xiaopeng, who was set up by the man of science and technology, did not understand technology, and also picked up BYD by the way.

Suspected of being sarcastic:

Previously, Wang Chuanfu said that autonomous driving is all nonsense, but the concept of being coerced and hyped by capital is ultimately an advanced assisted driving.

This scene of mutual strifeth is even more exciting than "China Rap Showdown".

He Xiaopeng wants to be slapped in the face by cognition?

Lao Hu first said that from the perspective of AEB's work characteristics, development and technical difficulty, some of He Xiaopeng's views seem to be a little untenable, which may also be caught by Yu Chengdong.

To put it simply, AEB stands for Automatic Emergency Braking System, according to the Insurance Institute for Highway Safety:

Models with AEB can reduce accident rates by 27 percent and rear-end collisions by 38 percent.

The U.S. Road Safety Administration has even proposed:

All new vehicles sold in the U.S. require AEB as standard. The American Standard IIHS and the European Euro-NCAP two major safety testing institutes have also directly included AEB in the scope of testing.

Models equipped with this feature have a higher active safety score.

Looking at it this way, He Xiaopeng's "99% of the AEB function is fake" obviously lacks arguments.

At the same time, He Xiaopeng also said:

At present, when talking about AEB in the industry, it mainly talks about longitudinal AEB, which should be within 60 kilometers per hour in most cases when triggered. If the speed is too high, once the brake is mistaken, it will be a huge shock to the user, which is simply unacceptable.

It also does not meet the characteristics of AEB.

There are about two ways to work, that is, when the distance from the obstacle is detected, through analysis and calculation, if it is less than the safe distance, it will be alerted first, and will not interfere with the driver's operation.

After the reminder, the AEB will only be activated after the driver does not make the action of applying the brakes.

The situation of false braking does exist, but the system will remind you first, so the huge fright is a bit exaggerated.

Finally, He Xiaopeng said: AEB is only done as one of the directions, we have been mentioning static AEB, once there are obstacles around, the vehicle will take the initiative to avoid, and it can't hit it if you want to.

Again, it is contrary to the development of AEB technology.

At present, the improvement of AEB performance is mainly due to the working speed range and the recognition ability of the system.

The working speed range has been increased from the traditional 30 km/h to about 60 km/h (leading car companies).

The recognition capability of the system focuses on the perception level, such as an independent pedestrian detection system, to improve the recognition accuracy of different road participants.

If the concept of static AEB is "you can't hit it if you want to", then it is also necessary to improve the detection range of different lanes, and the underlying logic is still to improve the performance of AEB, and the working logic is also inconsistent with the traffic rules of "give speed and don't give way".

More importantly, the attitude and understanding of AEB, which is the foundation for high-level intelligent driving and even autonomous driving in the industry.

Because everything is designed to assist drivers, improve road safety, and include all road participants, AEB is not optional.

Huawei AEB is leading again?

Judging from the test results of the third party, this is indeed the case, according to the AutoLab test, it can be seen that in terms of working speed and recognition ability, the M5 intelligent driving version is indeed a big step ahead of other competitors participating in the test.

And it's not just a third-party test.

We have shared it many times before, and in the latest test of Knowing Chedi in October, the AVATR 11, ARCFOX Alpha S, and Wenjie M5 equipped with Huawei's high-end intelligent driving also ranked in the top three.

In addition, judging from the performance of the new M7, Yu Chengdong complained: Friends lack the most basic understanding of the development of the automotive industry, and it is not without basis.

Previously, the AEB function in the automotive industry was indeed dominated by the longitudinal direction of the vehicle.

However, the new M7 has made its world premiere with an omnidirectional collision avoidance system that adds sideways and rear AEB capabilities and increases the maximum braking speed to 90 km/h.

As:

When the driver is distracted and the vehicle deviates from the lane, an obstacle is detected, and the vehicle can actively avoid driving into the right track; It is also possible to detect vehicles in the blind spot during merging, so as to avoid collision accidents.

Thanks to the visual perception system, the new M7 has a maximum detection distance of 200 m and a maximum detection angle of 120 °.

Recently, there is a popular little video on the Internet, I don't know if you have seen it.

The owner drove an AVATR 11 on the national highway, and there were few vehicles on the road, so the speed was not slow, the key was that the light on the road was very bad, and the human eye had a very limited line of sight.

Lao Fox has watched this video many times, to tell the truth, if I watch it myself, I may not be able to brake the car, I am afraid to think about it!

You can see how good this AVATR 11 is. As we all know, AVATR 11 also uses Huawei's ADS system.

This video has also been reposted many times by AVATR CEO Tan Benhong.

The old fox thinks:

With a large amount of data and practical proof, there is no doubt that AEB has improved driving safety, and the main development of technology in the industry lies in the improvement of recognition accuracy, range and working speed.

Under the rapid development of science and technology, the significance of high-end intelligent driving assistance to consumers is also not dispensable.

The solution is also very simple, it is a mule or a horse to come out and slip around, and everything depends on actual experience.
