Seeing Li Yifan's attitude, Zhou Yuanchao could only smile helplessly.

"Boss, it's not that I don't want to do it, but in this regard, we really lack people! This CVT is relatively easy to deal with. After all, this thing has been born for many years, and although it is not a mainstream product, there are still many models in use worldwide. However, the dual-clutch is not ordinary. Although this transmission has been born for decades, it has been abandoned by many car designers not long after it was born. Volkswagen has only picked up the cold rice in recent years. Although their new DSG transmission has been on the market, the specific consequences will be discussed now. After all, the problem of the previous DSG leak is very obvious. Whether Volkswagen can solve those problems has always been a key issue. And on the other hand, we are indeed lacking professional design talents in this area. I want to set up such a design team now, but it is difficult to find people!"

After hearing Zhou Yuanchao's words, Li Yifan felt that he was a little too hasty.

Indeed, he was anxious to catch up with the Germans and Japanese technology, but he forgot that our country has always been a shortcoming in design, and the main reason is the lack of talent.

In fact, we are not really lacking in professional design talents in our country, although the country's education has severely stifled the creative ability and design ability of a lot of students.

However, there are not people in China who have the ability to create and design. But people with such ability are now big players in the industry.

Either they serve as a business backbone in their respective companies, or they go abroad to earn high salaries, and there are very few who are willing to stay in China.

After Zhou Yuanchao returned to China and joined Chery, he formed a power transmission R&D department and served as the top commander. His main focus was on the CVT transmission.

As a result, it took six years to get my own CVT product done.

Byd started to engage in dual clutch back then, and it was only after Volkswagen's dual clutch were widely popularized in China. They began to do human-to-peer tactics and engage in reverse research and development.

Finally, it took four years to fully understand the public's technology.

Moreover, it was only after organizing a scientific research team of thousands of people that the success of reverse research and development was ensured. Now that he asked Zhou Yuanchao to form a team, he still hoped that he could achieve results within two years, which was indeed a bit too impatient.

"It seems that I am really too impatient, but Lao Zhou, time is endless! In the future, the development trend of the domestic automobile industry. I think you should also have your own judgment. In the next few years, there will only be more and more people buying cars in China, especially those living in cities. Their consumption level will become higher and higher, and more and more people in cities will have an immeasurable impact on urban traffic. I think congestion will become a very common phenomenon in domestic cities in the future, and this will greatly promote people's demand for automatic transmission models. Our hydraulic automatic transmission is a research direction, but you also know that when the hydraulic automatic transmission reaches six gears, it is actually a limit. There may be higher-end hydraulic automatic transmissions in the future, but such transmissions will also mean higher design costs and processing costs. Whether such high-end transmissions can be widely popularized in the future will be a problem."

Li Yifan's words made Zhou Yuanchao nod, and that's true.

When hydraulic automatic transmissions develop to six gears, it is actually a limit. It is undeniable that people can indeed create higher gears and more hydraulic automatic transmissions.

However, the internal structure of this transmission will be more complicated, and the shift logic, that is, the data processing of TCU will be quite complicated.

All signs indicate that the cost of such a transmission will be a big problem, and whether it will be popularized like low-level models in the future will become a big problem.

If it can only be used in luxury cars, what is the significance for many general public?

"The dual-clutch and CVT transmission are different. They have good gear shifting smoothness and stronger fuel-saving ability. This is their advantage. Although they also have their own shortcomings, in my opinion, these shortcomings were fatal in the past, but now they are not necessarily the case. Take the CVT transmission for example. Jetco has been persisting for decades, but now their CVT is getting better and better, and the reliability is getting higher and higher. The production cost of this CVT is actually not high, and the high one is just the later maintenance cost. In the past, the life of their CVT transmission was only 40,000 kilometers, or five years, but look at it now, their

The service life has reached 200,000 kilometers, more than ten years. Moreover, with the discovery of new materials and the application of new technologies, the service life and reliability of their CVT transmissions will be higher. Although they have never made any progress in dealing with intense driving, not all drivers are racers, not all consumers need to drive fiercely, and there are many consumers who like comfort. This means that their market prospects are broader. For example, the model they launched in North America now is very popular? In terms of reliability, it will especially give people a thumbs up."

Li Yifan's words made Zhou Yuanchao's heart churned.

When he began to enter the field of transmission research and development, hydraulic automatic transmissions were undoubtedly the dominant player in the field of automatic transmissions at that time.

Although some models of cvt are used, they are definitely niche products in terms of market scope.

At that time, 4at occupied an absolute majority in the automatic transmission market, and it was estimated that it would have to stand at more than 80% of the entire automatic transmission market share.

But now you are looking at it. With the improvement of technology, the 4AT transmission has begun to decline and the 5AT has also begun to enter the market. However, another phenomenon that cannot be ignored is that the CVT seems to be reviving.

So far last year, he had read a statistical report on JDP, which seemed to say that the market share of cvt transmissions in the automatic transmission market has increased from the original single digits to about 10% of last year.

The one that contributes the most is Nissan's Jetco. It is their persistent investment in research and development for decades that has enabled their CVT transmission to enter the sixth generation of products. The performance of the new product has been well reflected in reliability, and it has performed outstandingly in terms of fuel-saving performance.

There is still a Volkswagen dual-clutch transmission to disrupt the situation. Indeed, no matter how you look at it, it seems that the market for automatic transmissions is about to change.

Indeed, his premonition was not wrong.

More than ten years later, in the global automatic transmission market with a scale of tens of billions of yuan, the 6at transmission, the representative work of hydraulic automatic transmissions, has shown a decline.

If it weren't for some reliable performance, it would probably be almost wiped out by the dual-clutch transmission and CVT.

However, even so, the market share of 6at is the lowest-market hydraulic automatic transmission since the birth of hydraulic automatic transmission, accounting for about 30 to 40% of the entire automatic transmission market.

The automatic transmissions of dual-clutch and CVT have already occupied more than 20% of the market share of automatic transmissions respectively.

With the gradual improvement of technology and the continuous addition of new materials, the performance of dual-clutch transmissions and CVT transmissions has been continuously improved, and their market share has been continuously increasing.

The most representative of this is the dual-clutch transmission, which Volkswagen is the first to come forward to rehearse.

You have to say that the Germans have a very accurate vision. They have long seen through the problem that the hydraulic automatic transmission has limited room for improvement in the future and the cost will be greatly increased.

So we began to develop dual-clutch transmissions. In terms of mechanical structure, this transmission has inherent theoretical advantages over hydraulic automatic transmissions.

In the last century, this theory of double clutch was born, but at that time, because electronic technology was not advanced enough, double clutch could not become mainstream because there were too many problems.

But now, after the electronic control technology is very mature, this dual-clutch transmission has also ushered in a breakthrough.

Volkswagen took the lead in seizing this selling point and first came out to launch their dual-clutch transmission.

Although their dual-clutch transmission quickly exposed considerable problems, they have been persisting in this direction without retreating.

Later, Americans also joined in, and later Japanese people began to develop dual-clutch transmissions, and dual-clutch transmissions became the most talked about and most developed in the market.

Finally, after many improvements, the original problem of this transmission is that it is constantly decreasing, and the American Ford is the biggest contribution.

In the past, Volkswagen used to create a dual-clutch transmission to place the electronic control unit inside the transmission housing, but what they ignored was that once the car entered a congested section, when the car needed to shift gears frequently, the inside of the transmission housing would rise steadily, which would affect the sensory sensitivity of the electronic control unit, resulting in a transmission strike.

This problem has troubled Volkswagen for many years, but Ford engineers have taken a different approach. Their choice is to directly integrate the electrical control unit and place it on the outside of the transmission housing, so as to greatly avoid the problems encountered by Volkswagen.
