Chapter 385 A major breakthrough in 4AT
Automatic transmissions are nothing new to the world's automotive industry.
Products owned by various automobile giants are already equipped with automatic transmissions.
Especially in places where the automobile industry is relatively developed, consumers will have higher recognition of automatic transmissions.
After all, vehicles with manual transmissions are more troublesome to drive, and ordinary people still prefer vehicles that are simple to operate.
But for China, automatic transmissions are a scar that is difficult to uncover in the automotive industry.
Let alone 1985, even in 2000, or even in 2010, there were no decent automatic transmission products in China.
That is to say, after 2010, the entire industrial level has been greatly improved, and automatic transmission technology has achieved a relatively large breakthrough.
It is conceivable how much impact Nanshan Transmission will have on the industry when it announces that it has successfully developed a 4AT automatic transmission.
"Director Jiang, you skipped 3AT this time and developed 4AT, which is really beyond everyone's expectation."
After Lai Yongfeng, director of the Vehicle Engineering Department of Shenzhen University, heard the news, he immediately came to Nanshan Transmission to see with his own eyes whether the other party had really built a 4AT automatic transmission.
As an industry insider, he knew that the Capital Gear Factory had been working hard to develop 3AT over the years, but it had never been developed.
Now that Nanshan Transmission has developed the world's mainstream 4AT, the meaning is really very different.
This is not only a breakthrough in China's gearbox industry, but also a typical case of catching up with the world's advanced level.
Until now, no transmission company has announced that it has successfully developed a 5AT or 6AT automatic transmission.
4AT is already the most advanced in the industry.
Of course, there must be differences between 4AT and 4AT of different companies.
Just like the engine, it is also a 1.5L engine, produced by different manufacturers, and the performance varies greatly.
"First solve the problems that exist, and then continue to accumulate experience and improve the design of the gearbox control unit."
"Our current 4AT is no worse than ZF and Aisin Warner in terms of structure, but there is still room for improvement in terms of control logic."
Jiang Hui naturally doesn't have that much time to write code himself.
During the development process of 4AT, he could only provide the overall design plan, and the specific details still had to be implemented by the people below.
Otherwise, even if he could divide the work into two, the time would not be enough.
"Compared with manual transmissions, the most difficult part of automatic transmissions is indeed the TCU, which is the weakest link in our country."
"Fortunately, Nanshan Transmission has invested a lot of manpower and material resources, and also bought a lot of computers and related equipment from the United States. Otherwise, I don't know when a manufacturer will be able to produce 4AT."
Seeing that BMW Group has produced another major achievement so quickly, Lai Yongfeng is more confident in the development prospects of the Department of Vehicle Engineering of Shenzhen University.
The rapid development of the Department of Vehicle Engineering of Capital University of Technology in the past few years is inseparable from Zhu Jiansheng's successive hosting of some large projects.
4MT, BJ212, Humvee military vehicles, intercontinental ballistic missile launch vehicles...
The potential impact of these projects on Capital Institute of Technology is beyond words.
"The computer industry is a sunrise industry in the future. Our group has specially set up Nanshan Software to develop various industrial software. At the same time, we will cooperate with BMW, Nanshan Transmission and Nanshan Engine to develop some control parts."
"Like engines, all domestic gasoline engines so far use carburetors, and there is no electronic injection engine."
"But around the world, EFI engines have become a new trend, and high-end models are basically equipped with EFI engines."
"To develop an electronic injection engine, the most critical thing is the development of the ECU, the engine control unit."
“This not only requires relying on various empirical data accumulated in the past, but also requires a deep understanding of electronic components and software.”
"We are working hard now to develop an electronic injection engine in the next few years."
When communicating with scientific researchers engaged in R&D, it is natural to draw more big pictures on technology in order to attract people to the greatest extent.
By then, the teachers and students of Shenzhen University will be the resources of BMW Group.
This is still very important to promote the improvement of the BMW Group's research and development level.
"Electronic injection engine?"
"Have you started research and development yet?"
Sure enough, when talking about these things, Lai Yongfeng's eyes brightened a lot.
"Yes, but it is unlikely to be developed in a short period of time. At least we will have to wait until the next year to make progress."
Control parts, even in later generations, will still be a weak link in China's auto parts industry.
Whether it is ECU, TCU, VCU, ABS, ESP and other parts, almost all are produced by foreign parts companies.
Even for self-branded cars, the parts used are produced by foreign parts giants such as Bosch, Continental, Denso, Delphi, and Valeo.
That is to say, in the era of electric vehicles, a large number of local Chinese manufacturers began to appear in various control parts.
The BMW Group will start to produce these parts now, and Lai Yongfeng is naturally very aware of the difficulty.
Not to mention other things, the chip alone is a stumbling block.
"Let alone the year after tomorrow, even if we can achieve results in four or five years, it will be very remarkable."
"I can't see any hope for other domestic manufacturers."
Lai Yongfeng's words really came from the bottom of his heart, which further strengthened his determination to cooperate with BMW Group in the future.
Even without Zhu Jiansheng's relationship, he would have become a die-hard supporter of the BMW Group.
He had no reason to object to this kind of thing that was beneficial to both public and private interests.
"Everything is difficult at the beginning. There are too few domestic talents who are proficient in engine control management and computer technology."
"I think Shenzhen University can consider a postgraduate major in automotive electronics in the future, or directly establish a software engineering major to grasp the development direction of the industry as early as possible and become a leader in this field in China."
BMW Group now regards Shenzhen as its base, and naturally hopes that the strength and scale of Shencheng University can be greatly improved.
This way you can enjoy the benefits to the greatest extent.
"I'll go back and study it specifically before raising it with the principal."
"In terms of developing new majors, the school has ideas in this regard, but it lacks relevant resources and teachers, and further efforts are needed."
There is no teacher who doesn’t want his school to become better.
Only on a big platform can a person maximize his or her own strength.
Otherwise, the personal impact is very small. ……
Lai Yongfeng is not the first person to visit Nanshan Transmission to visit the 4AT automatic transmission.
In order to verify the authenticity of this information, the First Machinery Department specially arranged a team of experts to come over for inspection and exchange.
Li Nanhai, the director of the Capital Gear Factory, naturally found an opportunity to join the expert team and wanted to personally confirm whether the Nanshan gearbox was fraudulent.
He couldn't believe that the other party could develop a mature 4AT automatic transmission in such a short period of time.
"Director Li, your factory needs to work harder, otherwise in the future we will only rely on 4MT, a flagship product, and life may not be so easy."
This time, the expert team is not low-level, and they are all qualified to fly.
Li Nanhai and Qin Hao were seated next to each other, so it was inevitable that they would talk about the subject of this inspection.
"Qin Bureau, many of our technicians have been poached by Nanshan Gearbox in recent years. It will be difficult for us to work hard first."
Li Nanhai must be looking for some excuse for the Capital Gear Factory, otherwise wouldn't it mean that he has poor leadership?
Even if this was the case, he would never admit it.
The latest chapter of this book
Take a look at the 16-9 book bar!
"As far as I know, most of the technicians and engineers who left your factory did so because they wanted to retire early to make room for their children."
"If your factory develops fast enough and can completely consume these family members, then there will be no problem of personnel loss."
Qin Hao obviously sided with Nanshan Gearbox and directly helped Jiang Hui refute Li Nanhai's statement.
This is not the first time he has dealt with the Nanjing Capital Gear Factory. How can he not know the actual situation?
In today's factories, few would actively develop new technologies if their superiors had not assigned R&D tasks.
Of course, for most factories, objectively it is because when superiors have no tasks, there will be no R&D funds.
Without funds, it is naturally unrealistic to do things.
"You don't know how many educated youths have returned to the capital in recent years."
"Except Chaoyang Motorcycle Manufacturing Factory, which factory can completely absorb the families of its employees?"
"The current situation of our factory is pretty good. Everyone's wages and benefits can be paid on time, and a certain amount of profit can be paid to the superior department at the end of the year."
“Many factories now don’t even have basic wages guaranteed.”
Li Nanhai's statement basically represents his true inner thoughts. After all, to a certain extent, this can be considered a fact.
"You know best where your 4MT technology comes from."
"That means Nanshan Gearbox is merciful, otherwise you would still be able to live the good life you have now?"
When Qin Hao said this, Li Nanhai felt unhappy.
"So many domestic manufacturers want to produce 4MT. In the end, besides our factory, have other factories succeeded?"
"It's not that the Capital Institute of Technology doesn't consider providing technology to others, but that they need to have the level to put the technology into practice."
Li Nanhai would not dare to compete with Nanshan Gearbox.
After all, if the other party really starts to produce 4MT, then the good days of Capital Gear Factory will be over.
But looking at other gearbox manufacturers, Li Nanhai still has no pressure.
"Director Li, if we give you automatic transmission technology now, will your factory be able to put the technology into practice?"
Zhou Jian, who was sitting in the front, naturally heard the conversation between Li Nanhai and Qin Hao.
The 4AT automatic transmission is of great significance, of course he knows this.
But how high its gold content is, Zhou Jian still hopes to have a comparison.
If no domestic company except Nanshan Gearbox has the ability to produce this product, the meaning will be even different.
"We can produce most parts of the automatic transmission, but for the TCU and the matching torque converter, we still need support from the ministry to introduce a variety of new equipment and talents."
In front of Zhou Jian, Li Nanhai did not dare to speak nonsense.
If it works, it works. If it doesn't, it doesn't work.
Don't worry, if someone really puts the technical information of 4AT in front of him, it will be a big problem.
"The most critical parts of the automatic transmission are the TCU and the torque converter. If you can't produce these two parts, what's the point?"
Qin Hao interjected from the side, obviously ready to completely stand on the side of Nanshan Gearbox.
"The production of these two parts is indeed very difficult. I watched this kind of production line once during my inspection in Japan last year."
"Frankly speaking, Nanshan Transmission said that it has completed the development of 4AT. I am a little worried that the other party has only produced a few samples, and there is actually no way to install them into cars for mass production."
"After all, the automatic transmission relies on the TCU to control various gear changes inside. If the TCU is not designed well, the transmission will be damaged accidentally."
Li Nanhai began to apply eye drops to Nanshan's gearbox.
Anyway, it was just a guess. Even if Jiang Hui knew about it, there would be no way to accuse him.
"Just because you can't do it, it doesn't mean that Nanshan Gearbox can't do it."
"In order to develop TCU and other control parts, Jiang Hui set up Nanshan Software to develop various industrial software systems. Their core engineers have already started working on computers."
Qin Hao couldn't bear to hear Li Nanhai say bad things about Nanshan gearbox.
This company is a core subsidiary of the BMW Group and is likely to become another major export earner in the future.
Unlike the Capital Gear Factory, it can only provide supporting equipment to domestic manufacturers, and the supporting amount is still declining.
"Industrial software cannot be developed by just finding a few people. Just buying a computer will cost a lot of foreign exchange. At that time, a lot of money will be spent but the product cannot be developed. It would be more convenient to buy it directly from abroad. ”
As the director of the Capital Gear Factory, Li Nanhai also experienced the role of industrial software in design work when he was in Japan.
In his opinion, the right way to quickly catch up with others is to directly use the same software to develop products with others.
Otherwise, if we have to develop and design software ourselves, wouldn’t the day lily be cold?
He is definitely not the only one who has this idea.
"We will find out how good the 4AT produced by Nanshan Transmission is when we go to the site tomorrow."
Zhou Jian saw that Li Nanhai and Qin Hao were about to fight, so he made a fight beside him.
Both of them are his old subordinates, and He Xini is the best solution.
