For the gift, start research and development of graphene batteries

Chapter 94 The hardware has changed a lot
"No, no, such an increase in cost is unacceptable to car companies."

Qin Ruya said.

Even if it is known that additional cameras can improve the effect of autonomous driving, it is still inappropriate after comprehensive consideration.

Moreover, the technical difficulty is not at 01:30. The entire team has never done this before, so it is a bit inappropriate to suddenly change the plan now.

"Sister Qin, you may not understand my plan. What I mean by adding cameras is not necessarily to increase the number of cameras, but to adopt an idea similar to the main camera and the secondary camera."

Seeing the reaction of the crowd, Jiang Ming said this.

"Main camera and secondary camera?"

Liu Ming asked, a little confused.

The camera collects the information of the outside world through the sensor, and transmits it to the controller through the change of the potential.Then the controller processes the collected information and restores it.

This means that the image we see is actually displayed after the controller is virtualized.

This re-restore program, although more convenient.But compared with the traditional rubber method, there is a gap in the details.After all, due to the influence of the sensor, no matter how high the pixel of the camera is, it is impossible to completely restore it, and there will always be distortion.

This is especially true when imaging at night.

Therefore, in order to achieve higher imaging standards, it is relatively common in the mobile phone industry to use the mode of the main and secondary cameras.

The main camera is responsible for the overall perception and imaging of the environment, strives for the integrity of the picture, and does not pursue too much detail.

After the main camera perceives the environment, the two sub-cameras supplement the details.Finally, the images sensed by the three are completely restored after being processed by the controller.

This is the function of the camera, which corresponds to the autonomous driving technology and is a supplement to the modeling details.

Using the analogy of building a house, the main camera is responsible for building the overall frame of the house.The secondary camera is responsible for processes such as painting and whitening. The two work together to ensure that the house meets standards.

The purpose of this is to establish a streamlined imaging process to maximize the efficiency of visual perception and improve the efficiency of modeling.

Moreover, the pixel accuracy of the main and secondary cameras is also different.Even more, in order to improve the accuracy of autonomous driving at night, the secondary camera can be replaced with a type that performs better at night.

This also avoids the inaccuracy caused by the single camera and the perception of the environment.

Jiang Ming explained his thoughts to everyone one by one. Hearing Jiang Ming's explanation, Qin Ruya looked thoughtful.

Regardless of whether it can be done or not, Jiang Ming's idea is quite bold.

As for Liu Ming, he is not a general proficient in hardware. He has more ideas about Jiang Ming's plan.

"Jiang Ming's idea of ​​one master and two assistants is feasible in principle, and although it has an impact on the cost, it is also within the acceptable range. But this kind of solution has basically never been done in the industry before. In terms of software, , can be very complicated.”

Liu Ming expressed his thoughts.

The key point of automatic driving is the establishment of models.Especially in complex working conditions, such as downtown.How to mark all the targets in the shortest time and let the system recognize them is the key point.

The three-camera mode can expand the range of recognition to a certain extent.In addition, it has advantages in quickly building models.

But how to put it, faster collection and more perspectives mean that the data that needs to be processed will also increase exponentially.The difficulty of this has not been improved by a single star.

"In terms of software, we can think of a way. According to Zhang Ru's ability, there should be a way to solve it. It's nothing more than a problem with the usage rate of the secondary camera."

Qin Ruya thought for a while and said this.

Hearing Qin Ruya's words, Jiang Ming was a little speechless. He proposed a camera mode with one main camera and two secondary cameras. It's not for you to use it as a single camera.If so, what is the meaning of the change?

However, if the hardware can be modified in this way first, then there will be a chance for the follow-up strategy.After all, the software side will be much simpler than the hardware side.

"I'll keep talking."

"The second point is the wireless control module. I suggest raising the standard and directly adopting the 6G module. In this case, there will be great advantages in data transmission."

Jiang Ming said.

"What, isn't the 6G module not yet commercially available? Isn't this a bit whimsical?"

Liu Ming said so.

Everyone knows that higher communication standards mean lower latency, but it doesn’t mean you can do whatever you want, it depends on the conditions.

"I checked the information before. In a specific area, Juchang has carried out 6G verification and it has been used on a small scale. I believe that if we negotiate with Juchang in the name of Xia Keyuan, it is possible to use 6G modules. possibility."

Jiang Ming analyzed.

Hearing Jiang Ming's words, Qin Ruya nodded.Juchang has started the development of 5G after the commercial use of 6G, and has samples.

In the name of Xia Ke Academy, this is really possible.

"Okay, this is also within the scope of consideration, I will try my best to coordinate."

Qin Ruya said so.

Jiang Ming beamed when he heard Qin Ruya's words.It is said that it is easy to enjoy the shade under the big tree. The name of Xia Ke Academy is that it is easy to use. If this is its unit, it is a no-brainer.

Of course, if Jiang Ming is determined and asks Academician Long to coordinate, there will be no problem.But it would be a bit hard to think of coordinating such a small matter with an academician.

"Any more?"

Qin Ruya was very happy that Jiang Ming was able to raise so many ideas.

At the beginning, Jiang Ming was drawn into the team because he had more ideas. Looking at it now, he was indeed right.

Qin Ruya is even considering whether to recruit more outsiders for the follow-up research and development work.

After all, the old people in the hospital have been in this circle for a long time, and their inherent thinking is too serious.It is really not easy to be a little innovative.

Qin Ruya is quite looking forward to Jiang Ming's next opinions.

"Otherwise, it's something special. I hope you can consider it, Sister Qin."

Jiang Ming was vaccinated in advance.

"Oh, something special, let's hear it?"

Qin Ruya became interested.

The previous one-to-two camera solution is already special enough, is there anything different?
"In order to solve the problem of insufficient self-learning of the neural network in the algorithm, I suggest deploying a micro server in each vehicle for the interconnection between vehicles."

Jiang Ming said.

"I don't understand, what is the purpose of doing this?"

"It stands to reason that the 6G network transmits information in real time, and the central server can continuously download data, which should allow the self-learning function of the neural network to grow. Why do we need to spend a lot of effort to deploy micro-servers?"

A team member said so.

Qin Ruya also looked at Jiang Ming doubtfully.

Generally speaking, autonomous driving technology is like this. The system will continuously exchange data with the server through the network and update internal data.

Some special situations, such as accidents or traffic jams, can also be updated based on server information.The vehicle-machine system will adjust the autonomous driving strategy in real time based on this information.

In this process, enough discrete data is needed for the central server to learn.According to real-time road conditions, different instructions are given.

This kind of discrete system, in fact, the car-machine system is simple, and the complex one is the central processing unit.

After all, the car-machine system is only at the operational level, and it is the central processing unit that involves decision-making.

Although this method is good, operation problems will occur when facing network delays or other special conditions.

In order to solve this problem, Jiang Ming plans to deploy a micro service network on the vehicle for mutual communication between the vehicle and the machine, so as to get rid of the dependence on the central processing unit to a certain extent.

The core of this solution is that as long as the vehicle equipped with the intelligent driving system is not far away, it can exchange data, update the local log, and adjust the strategy.

The adjustment of this strategy will be fed back to the central processing unit after running for a period of time.The central processing unit dynamically adjusts the large operating rules of automatic driving according to thousands of actual vehicle strategies.

In this way, the two complement each other, and finally perfect the neural network of the automatic driving system in the shortest time.

"This, isn't this too advanced?"

Liu Ming said this when he heard Jiang Ming's plan.

"Yes, the interconnection between vehicle and computer systems is a good idea, but it will be very difficult to implement. We need to solve the problems of identification, information interaction, and policy update. The amount of data will be very large."

Liu Ming analyzed it like this.

"No, we don't need to make the network server in the car-machine system very large, as long as the data is exchanged within a period of time. After all, with network assistance, the central processing unit will store most of the data."

Jiang Ming said.

"Let's write this down first, and ask Zhang Ru later to see if she can realize it."

Qin Ruya didn't make a decision immediately, but said this.

"In addition, there are some common improvements. For example, the large intelligent network screen can display the status of the vehicle in real time. It is best to display the status of the model in real time."

"As for lidar, I suggest canceling it. In high-end models, lidar is generally not installed, and this time it is pure vision. If you are worried about visibility, you can choose an infrared camera, which can have a certain balance."

Jiang Ming suggested.

Hearing Jiang Ming's words, Liu Ming's eyes lit up, this is okay.

LiDAR is not cheap. If it can be left, that would be the best.

Next, Mr. Lin Lin, Jiang Ming, said another part.

Looking at the entries in the notebook, Qin Ruya also had a headache.

At first, I thought Jiang Ming was just expressing his views routinely, but he didn't expect that so many items would be listed in the end.

Qin Ruya counted nearly 20 improvements.

Some of these improvements are not bad. They just add some equipment, which is not very expensive. I just added them if they felt reasonable.

In addition, there are some improvements to the vehicle.

For example, adding a collision sensor.

Intelligent driving vehicles generally have collision sensors.In most cases, it is mounted on the front of the vehicle.

But according to Jiang Ming's design concept, collision sensors need to be added not only to the front, but also to the sides and rear.

In addition, regarding the suspension of the vehicle, Jiang Ming felt that some improvement was needed.

Previously, the suspension of the Siris vehicle was fixed and could not be adjusted.

Jiang Ming's opinion is to change to an adjustable air suspension.

After this change, the passability of the vehicle has been qualitatively improved.According to Jiang Ming's vision, when the vehicle is difficult to pass or needs to be adjusted, the driving system will automatically adjust the suspension to improve the driving experience to the highest level.

In this way, the vehicle that was originally slightly modified became a major modification under Jiang Ming's suggestion.

It wasn't that Qin Ruya was selling Jiang Ming's face, so she had to change like this.But the whole team felt that many of Jiang Ming's opinions were quite reasonable.

Anyway, quite an idea.

As for whether these improvements can be realized through the automatic driving system, everyone does not hold much hope.

But keeping these ports is better than nothing, just in case it can be realized.

All in all, in the factory of Seris, everyone worked hard for half a month, and finally finished the prototype car.

Looking at the unrecognizable vehicle in front of him, Jiang Ming was a little speechless. This change was really big.

First of all, the hood of the vehicle has become streamlined and more sporty.

On the hood, there are many temporary sensors used to detect vehicle status and vehicle parameters.

In addition, there is a huge mosaic camera in the four directions of the front, rear, left, and right of the vehicle.This is the eyes of the autopilot system, used for environment perception.

In order to find this kind of high-resolution, infrared sensor, and main and secondary cameras at the same time, Qin Ruya took great pains.

In the end, it was soft grinding and hard foaming, and the manufacturer made a batch.

This time the vehicle's eyes-less dilemma is over.

Entering the interior of the vehicle is a variety of complex equipment.These devices are used to collect vehicle data, including driving video data, status data, policy execution logs, etc., to assist in tuning the automatic driving system.

After the real challenge begins, the data from these devices can also be used to judge the intelligence of the driving system.

Thanks to the cooperative factory of Siris, the various wiring harnesses and various interfaces on the vehicle were specially made by Siris engineers working overtime.

This car is currently considered an engineering car. Although it looks a bit messy, it has a full sense of technology.

Coupled with the unique tough guy style of the Siris model, it is believed that with the blessing of the automatic driving system, it will perform very well.

If it is said that the automatic driving system can really do a good job, it has reached the conditions for mass production.After removing many detection harnesses, the Siris will be extraordinary.

The major modification of the vehicle hardware has been completed, and the next step is of course the software debugging.

Because most of the members of Xiake Academy are in Kyoto, this car will be transported to Kyoto for joint debugging and testing.
