Chapter 158 My Suggestions

“This question raised by the leader is very professional and critical.

This is also a question I have studied for a long time.

It just so happens that the leader in charge of the automobile industry is here today, so I will share my opinions and plans.

If there is anything inappropriate, ask the leader to point out and correct it. "

The tall man nodded:

"It's okay, just talk freely. Everyone happens to be here today, and we just take this opportunity to discuss it with the entrepreneurs.

It is also about absorbing more fresh information and research ideas to find practical and efficient development paths.

After all, everyone’s ultimate goal is to have the same part and promote the progress of national science and technology and industry. "

Cao Shen cleared his throat and said:

"I suggest that the country vigorously develop new energy vehicles!

And it is an electric vehicle with a completely new electronic and electrical architecture.

This is also the direction I plan to research. What the leader just said is indeed very reasonable. As a third-party organization that only provides high-precision maps, it may face many practical problems.

Therefore, I plan to make the car myself first, and then open up the technology after the results are achieved, so that more car manufacturers can share the technological progress. "

Old Man Yu blurted out first, his voice getting a little shrill: "What? Do you want to make your own car?"

Weren't we just talking about making high-precision maps? Why are we talking about making cars?

After all, the high-precision map belongs to the information industry and is under my control. I asked the industrial port man to give me a platform, which means that he can give you a path when you enter the car factory in the future.

Stop by the security side to help clear the way.

You want to make a car now!

I glanced at the tall man and realized that it was under his control!

If you want to make a high-precision map, our department will take care of it.

If you make a car and become famous, then it will be other people's political achievements!

Contrary to the difference between Yu and the old man, the tall man was extremely happy. Cao Shen originally liked him, and the completion of the high-precision map would also be a boost to the automobile industry.

Now, if this kid wants to make a car, it will be directly under his hands.

This is great!

“Of course, high-precision maps will definitely be made available to domestic car manufacturers by then. After all, there is no need to do repetitive work.

And this part belongs to information and data processing, which we may be better at. "Cao Shen looked at Old Man Yu and immediately added.

This means that when the self-driving car industry develops in the future, your contribution will also be huge.

Old Man Yu felt a little relieved. Yes, what I said before, high-precision maps are the foundation, the foundation!

The tall man also smiled and said to the old man:

"The new electronic and electrical architecture that Cao Shen mentioned, I guess, will require our two departments to work together in the future!"

Oh, it seems that the tall man is really knowledgeable and knows the general direction of what he wants to say.

Cao Shen admired the tall man a little. It was not easy for a senior leader to still pay attention to such technical "details".

Moreover, cognition is already very advanced.

He can realize that the new structure requires the cooperation of two departments, which means that he has some ideas about this new structure.

You know, this new architecture was first proposed by the former Bosch in its automotive electronic and electrical architecture technology roadmap in 2015.

Of course, it was Tesla who did not propose it earlier but directly started doing it.

Therefore, Tesla's entire electronic and electrical architecture is actually about five years ahead of most traditional car manufacturers.

The tall one explained:

"EEA, Electrical/Electronic Architecture, was first proposed by Delphi.

It is a vehicle electronic and electrical solution concept that integrates the design of the vehicle's electronic and electrical system principles, the design of the central electrical box, the design of connectors, and the design of the electronic and electrical distribution system.

Now we usually use a distributed architecture. Under this architecture, high-end cars use 100 to 200 different ECU electronic control units. Various ECUs work together to provide various functions for the driver.

However, the new four modernizations of automobiles, electrification, intelligence, networking and sharing, are recognized trends in the industry.

In the face of this trend, the disadvantages of traditional distributed architecture are becoming more and more obvious.

At present, car manufacturers are gradually merging some ECU functions into one ECU to reduce control nodes.

The controller is developing towards "domain" integration to alleviate some problems.

But this is obviously just a transition, so I especially want to hear Mr. Cao’s views. "

"Yes! Under the trend of the new four modernizations of automobiles, this distributed architecture will face various challenges such as functional safety, real-time performance, bandwidth bottlenecks, and computing black holes.

I believe that the automotive electronic and electrical architecture will accelerate its migration from traditional distributed architecture to control domain and centralized architecture.

What the leader just said about integrating more functions into fewer ECUs is actually the concept of 'control domain'.

Currently, there are mainly power domain, body domain, assisted driving domain, chassis domain and infotainment domain on the vehicle. Domain controllers can complete the coordination work within their respective domains.

The domain centralized architecture can centralize the originally dispersed computing power, reduce complexity and increase the system computing power.

But I don't think this is the end state. "Cao Shen said.

The black-faced man said very excitedly:

“So, the end state should be a central computing platform architecture?

Only in this way can we have the greatest concentration of computing power and a high degree of coordination.

Autonomous driving requires powerful computing power, real-time control, and centralized scheduling.

Therefore, centralized architecture is the best solution for autonomous driving!

Moreover, if this is done, a holistic operating system can be built, and the software and hardware can be decoupled so that the car software can be plug-and-play, and it has the ability to be continuously upgraded! "

"Yes! That's right." The leader is still very capable, Cao Shen said.

Except for the tall man, Old Man Yu, and the Science and Technology Commission, seeing the confusion on the faces of the others, Cao Shen quickly added:

"After making this into a central control domain, the car can be understood as a computer.

There is a unified operating system, various software that is easy to install and uninstall, and online upgrades can be achieved.

If the current car encounters a software failure or needs to be updated, we must drive the car to the 4S store for the staff to use a professional computer to repair it, which is very inconvenient.

In the future, if there is a central control and operating system, it can be repaired and upgraded online. "

The crowd was relieved and nodded in agreement to show that they understood.

Old Yu was happy now, I like this metaphor!

Computers, although they belong to industry, they also belong to the information industry!

So, in the future, cars, hehe...

"Why can't traditional cars do this kind of convenient software upgrade?" The round-faced lady asked without shame.

Cao Shen smiled and replied:

"Most of the early cars were mechanical structures, and it was basically impossible to upgrade the vehicle with software. The general upgrade was limited to the in-vehicle entertainment system and navigation.

This is also the core reason why I advocate the country to vigorously develop electric vehicles.

The structure of electric vehicles is relatively simple. All systems related to vehicle driving, such as the power system, braking system, battery management system, etc. of the whole vehicle can be turned to electronic, so that they can be "controlled" and "rewritten" at any time.

As long as the manufacturer leaves more redundancy in the core three-electric system, vehicle processor, sensor, etc. in the early design, it will be much easier to improve through software in the later stage. "

The round-faced lady continued to ask: "What is the three-electric system?"
