Becoming the richest man starts with making complaints

“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 views 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 my own car 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 good!

“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 inherently requires powerful computing power, real-time control, and centralized scheduling.

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

Moreover, if this is the case, we can build an overall operating system and achieve decoupling of software and hardware so that automotive software can be plug-and-play and have the ability to sustain iterative upgrades! "

"Yes! That's right." The leader still has two skills, Cao Shen said.

Except for the tall man, Old Man Yu and the Science and Technology Committee, Cao Shen quickly added after seeing the confusion on the faces of everyone else:

“After this is made into a central control domain, the car can be understood like a computer.

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

If today's cars encounter software failures or need to be updated, we have to drive the car to a 4S store and have the staff use professional computers 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. "

Everyone was relieved and nodded cooperatively to express their understanding.

Old man Yu was happy now. I like this metaphor!

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

So, for future cars, hehe...

"Then why can't traditional cars have such convenient software upgrades?" the round-faced lady asked shamelessly.

Cao Shen replied with a smile:

“Most of the early cars had mechanical structures, and it was basically impossible to upgrade the vehicle through software, and general upgrades were limited to in-car entertainment systems and navigation.

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

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

As long as manufacturers leave more redundancy in the core three-electric system, vehicle processor, sensors, etc. during early design, it will be much easier to upgrade through software in the later stage. "

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