For the gift, start research and development of graphene batteries

Chapter 108 Terela hides so deeply
Seeing that Truss did not cooperate, the organizing committee was a little dumbfounded.

Faced with questions from netizens, the organizing committee had no choice but to do it themselves.

The organizing committee has its own technical consultants and hired well-known domestic technical experts to provide technical guidance.

It stands to reason that such technical experts generally give some suggestions on large-scale projects, and generally analyze technical problems, and these experts do not need to take action.

This time, the issue of Terela was more serious, and technical experts were just able to contribute.

Originally thought it was just a matter of hand, who would have thought that the technical experts did not analyze the reason. According to the expert's suggestion, it is still necessary to have in-depth communication with Telala and get some data before they can draw a conclusion.

Analyzing the video alone doesn't make much sense.

It's just that Tesla's attitude prevented the organizing committee from getting the core data, which was a bit difficult.

Of course, Tesla does not say that it will not give it, but it shows that the data of Tesla is stored in the cloud and is encrypted.

To retrieve this part of the data, very complicated procedures are required.This mechanism is for the sake of customer data security. All vehicles, as long as they are connected to the cloud, are treated the same.

The organizing committee can apply immediately, but according to the current situation, it is really impossible to get it for a while.

Netizens are all waiting to see the results. Without a preliminary analysis, netizens will not do it.

In the end, the organizing committee was forced to have no choice but to hand over this problem to the New Energy Industry Association.After all, the New Energy Industry Association is known as a co-organizer.

Wang Mingyang was a little speechless after receiving the request to analyze the cause of the Tela vehicle failure.

The New Energy Industry Association sent a liaison officer to participate in the competition this time, just to name it, so they are going to take on this kind of work?

Originally, this autonomous driving challenge had nothing to do with the New Energy Industry Association.

But in Xia Kingdom, in theory, someone needs to manage such a large-scale event.No, it's up to the New Energy Industry Association to pick and choose.

Considering the strength of the organizer this time, the industry association does not need to worry about it at all, so the industry association did not pay much attention.

Now that the request has come to this point, it is hard for Wang Mingyang to refuse.

But this problem, Wang Mingyang felt really difficult to deal with.

After all, the industry association is only a platform for everyone to communicate, and there is no very strong expert team.The work that can be done is just threading the needle and finding the corresponding person for the other party.

"Who are you looking for?"

Wang Mingyang thought in his mind that for a while, he really didn't have a good idea.

After all, the other party is Terra, who is the leader in the entire new energy industry, and most people really dare not offend him.

"Hey, isn't Jiang Ming at Qinghai Lake? Let's see if he understands the scene?"

Wang Mingyang thought so.

The problem now is that technical experts do not know the actual situation, and it is difficult to analyze it simply by relying on video.If you can have detailed data, it will be much easier to analyze.

Jiang Ming was on the scene and had relatively easy access to the data.

At this time, Jiang Ming is doing his best to deal with the remaining items of the challenge.

Although Jiang Ming has confidence in the self-driving system developed by Xiake Academy, it is the first time to show it to the outside world, so Jiang Ming is still very concerned.

Seeing Wang Mingyang's phone call, Jiang Ming was very puzzled, why did he call himself at this time?

"Hey, Mr. Wang, what's the matter?"

Jiang Ming opened his mouth and said bluntly.

"Jiang Ming, it's like this. In this challenge, there are some problems in the team that Tesla is in. Do you know, let's see if we can collect some data on the spot."

Wang Mingyang told Jiang Ming about the problem that the brakes of the special brakes almost failed, and then said so.

"What, the brakes of Tesla's vehicle almost failed? No way, Tesla has been studying autonomous driving for so long, how could there be a problem with this basic operation?"

Jiang Ming was very puzzled and said this.

"There is indeed a problem now, and there is video evidence, I will send it to you."

While talking, Wang Mingyang sent the live video to Jiang Ming.

At the same time, in order to let Jiang Ming understand his own thoughts as much as possible, Wang Mingyang sent Jiang Ming the explanations of other experts and the responses of Tesla.

After hanging up the phone, Jiang Ming studied the information carefully.

To be honest, Jiang Ming didn't believe the brake failure.

You must know that the function of braking is the highest authority in the automatic driving system.This means that when the command to brake is given, the system will free up all resources to do a good job of braking.

There are no other operational impact issues.

As for what Telala explained, the car did not have a brake failure, but a problem with segmented braking. Jiang Ming felt that the other party was purely farting.

This kind of explanation is okay to fool a layman, and those who pay attention to this matter are basically people with some car-related technical reserves.

Terra did not brake properly.

It's just that, as others have analyzed, in the second half, another system of Tela was activated, forcibly braking the car in a short time.

This can be reflected from the fact that the front brake marks are very shallow and the rear brake marks are very deep.

As for the reason why Tela did not admit it, it will affect the image of Tela in the hearts of consumers and affect the sales of products.

The problem now is to analyze why the special car can't stop in the first half, and why it stops in the second half.

The first question, why he couldn't stop in the first half, the reason should be similar to Zou Ming's analysis before.

It should be that there is a BUG in the software, which leads to excessive energy feedback of the system under certain circumstances, which weakens the braking force.

This kind of BUG is likely to occur with a very low probability.

However, due to the huge sales of Tesla vehicles, there are still a considerable proportion of cases where the brakes cannot be stopped.

In view of the accidental nature of this situation, Jiang Ming suspected that even Tracela could not find the problem.

Otherwise, with OTA technology, it is not a matter of minutes to repair the software.

This point can only be analyzed so far.

As for the second point, why did the brakes stop in the second half.

Judging from the video, the braking system of the Tesla vehicle should have been involved in the second half.

Before that, the energy recovery system intervened, and in the second half, the braking system intervened.

It's just why the braking system is forced to intervene, it must be the key data obtained, and then the operation is made.

In other words, the brakes in the last section are the insurance for the brakes of Tesla vehicles.

Could it be said that Tesla realized that this problem could not be solved, and then added additional corresponding equipment, so that the vehicle has another layer of protection when the vehicle cannot be stopped?
It seems possible that this system must be independent.Only in the event of failure of the first layer will protection be applied.

Occasionally, there were problems with the vehicles sold before, which meant that Tesla had made special modifications to the participating vehicles.

And it cannot be solved by software alone, it needs the cooperation of hardware.If so, then the problem is easy to troubleshoot.

Regarding the hardware configuration of the whole vehicle, the contestants have submitted it to the organizing committee, and they will come from the organizing committee, and then compare it with the configuration of the previously sold vehicles, and they must be able to find the answer.

Moreover, in terms of hardware, there are actually only a few things that can give key data.

Thinking of this, Jiang Ming knew it.

"Old Wang, it's like this, I need the hardware configuration data of Tesla's participating vehicles?"

Jiang Ming called Wang Mingyang and said this.

"What do you want Tesla hardware data to do?"

Wang Mingyang didn't understand Jiang Ming's plan.

Originally, I asked Jiang Ming for on-site data, but why did I want to provide Jiang Ming with data? Did Jiang Ming make a mistake?

Wang Mingyang asked while thinking this way.

"If the hardware data can be obtained, Telala's question can be answered."

Jiang Ming said so.

"What, there will be results so soon, Jiang Ming, are you sure?"

Wang Mingyang asked, very puzzled in his words.

It's no wonder that Wang Mingyang didn't trust Jiang Ming, it was because Jiang Ming's behavior was a bit unexpected.

Originally, I just wanted to inquire about the situation, but unexpectedly, I found a solution.

Wang Mingyang was still thinking about who to ask to solve this problem if he got the information on the scene.Fortunately, Jiang Ming had an idea directly, and only through public videos and images.

To be honest, Wang Mingyang was overwhelmed by Jiang Ming.

"It's about the same. What it is, we have to wait for the parameter configuration."

Jiang Ming said so.

"Jiang Ming, if you are sure, then I would like to ask you to help solve this matter. It is a favor I owe you."

Hearing Jiang Ming's certain words, Wang Mingyang stopped talking nonsense, but said this.

It should be said that Wang Mingyang and Jiang Ming have been cooperating for some time, and trust has been established between the two parties.

In Wang Mingyang's impression, Jiang Ming was very reliable in his words.

Many unreliable words in the eyes of others were uttered from Jiang Ming's mouth, and Jiang Ming finally realized them one by one.

This is also the case with the autopilot.

Although rationally, Wang Mingyang felt that Jiang Ming couldn't solve it.

But combined with past experience and Jiang Ming's words, Wang Mingyang felt that Jiang Ming was sure.

After all, before, Wang Mingyang did not expect that Jiang Ming could preside over the research and development of carbon-based batteries.It is precisely because of trust that Wang Mingyang gave Jiang Ming a chance, and finally made the carbon-based battery a product.

This time, Wang Mingyang still chose to trust Jiang Ming.

"Old Wang, please be polite. If you need anything, just tell me."

Jiang Ming said politely.

"That's fine, I'll let the officials of the organizing committee of this challenge contact you and let them send you the information directly."

Wang Mingyang said so.

"Alright then, I'll wait for them at the location of the Xia Ke Academy team."

Jiang Ming replied.

The office of the Organizing Committee of the Qinghai Lake Autonomous Driving Challenge heard that the person who could solve this problem was among the participating teams. Wang Wei, the technical director of the Organizing Committee of the challenge, vomited blood a little.

Okay, there is such a capable person, and I don't even know it?

When he got the team information of Xia Ke Academy, Wang Wei was speechless.No wonder I haven't heard of it. It turns out that the team of Xiake Academy has not made any decent products for so many years, and it belongs to an extremely ordinary team.

Jiang Ming, is this name so familiar?

Wang Wei couldn't remember for a while.

When Wang Wei came to the Xiake Academy team and met Jiang Ming, Wang Wei suddenly realized that this is Jiang Ming, the inventor of carbon-based batteries?

It's just that Jiang Ming didn't research lithium batteries. When did he change to an automatic driving system?

No matter, just provide the information as required. As for whether it can be solved, it is not something I worry about.

Anyway, according to my ability, I can't solve it.

Jiang Ming looked at Wang Wei's strange eyes, how could he not understand what Wang Wei was thinking.

Originally, Jiang Ming wanted to explain, but after thinking about it, Jiang Ming felt that it didn't matter.

These people are not familiar with themselves at all, so what's the use of explaining more.If you have this time, why don't you take a good look at the information and improve your knowledge level of science and technology.

Jiang Ming took the materials handed over by Wang Wei, and began to study them.

Although the team handed over brief information, not confidential.However, due to the extremely complex design of the vehicle, there is still a lot of information.

Even though Jiang Ming was more energetic, it took nearly an hour to finish reading the information.

After reading it, Jiang Ming sorted out all the configurations, and then compared them with the information on the Tesla official website. In the end, Jiang Ming found the difference.

In terms of hardware configuration, LiDAR has been added to the latest model of Tesla.

This lidar is integrated on the front camera.

It is similar to all Trinity cameras of Xia Keyuan, except that this one integrates lidar for distance sensing.

Generally, laser radars are relatively large in size and consume relatively high power consumption.

But this integrated lidar is small in size.

In this case, the sensing distance will be smaller and the frequency will be lower.

Of course, compared with the traditional lidar, the cost of this small-sized lidar will be much lower.

Coupled with being integrated with the camera, the impact on total cost is limited.

At the beginning, Jiang Ming didn't notice the difference in the camera either.After Jiang Ming corresponded one by one, he discovered that the model of the camera had changed.

For this reason, Jiang Ming logged on to the website and looked up the parameters of the two cameras, only to discover the difference.

The change in this camera model is pretty inconspicuous.

It is mostly reflected in the digital change at the end of the camera model. If you don’t check the data sheet carefully, it is easy for professionals to ignore it.

At the beginning, Jiang Ming considered the external sensors added by TELA, and wanted to find the problem through the configuration list.

But who would have thought that Terra hid the equipment so deeply.

If you look at it this way, the problem that Tesla vehicles cannot brake in the market does exist, and Tesla has not found the cause of the problem.

Tesla hopes that the extra sensors will be able to brake in an emergency to avoid accidents when there is a problem with the vehicle.

Due to the small size of this lidar, the distance that can be perceived is limited.

As a result, the brakes in the second half are activated within a very short distance.
