Time is like water, never looking back. Dolphin Technology's tense and constant technological farming stage lasts for three years.

Yes, in a blink of an eye, it was 2000, and so many things happened in these three years.

First of all, Mo Qingying also gave birth to a son for Wang Yong, named Wang Siwu. The little guy is two years old and fat. He follows his brother to play wildly every day. The two brothers have a companion. Wang Yong's family is like a battlefield every day, making a mess, and it's very lively.

In the past three years, apart from scientific and technological farming and solid basic technology, Dolphin Technology has not opened up new research projects.

Sometimes the manpower is exhausted, and Liu Meijuan and the entire R&D team have no more energy to develop other projects.

But it is not right to say that there is no at all, because Miao Wei’s team and others are working on small car projects.

But they don’t have many people, and they have always had more than 20 people. After the new three-cylinder engine was fully mature two years ago, they began to study CVT automatic transmission technology.

CVT automatic transmission is the simplest structure among all automatic transmissions, but the simpler the more difficult it is, the more technically difficult it is. The main reason is that the material requirements are very strict, and ordinary companies can only be discouraged.

CVT continuously variable transmission has a long history, and axially adjustable cone disc width V-shaped tape continuously variable transmissions appeared in 1899.

Its biggest advantage is its smooth speed, good driving experience, excellent linear acceleration, and no delay or thrust.

This is where it outperforms several other automatic transmissions.

Riben started researching in the early 1990s and has now achieved the best in the world.

However, the biggest disadvantage of CVT transmission is that it cannot withstand large torque due to tape or steel tape material, and is generally used on small-displacement models.

Because of this fatal disadvantage, some companies have begun to study the ring-ring disc balance-type continuously variable speed technology.

However, Dolphin Technology is different from ordinary automobile companies. It does not remember the cost investment for three years. In the field of materials research, Dolphin Technology has become the de facto giant in this world.

The materials research led by Bi Haibo was born, many of which were afraid to be released and were temporarily sealed. For example, some alloy single crystal materials have abnormal performance and are a bit shocking. Wang Yong and Liu Meijuan dare not take them out to show off.

However, some existing materials abroad, such as carbon fiber materials, are not scruples, and are nothing more than a little better than those abroad.

Carbon fiber materials are a key research field designated by Liu Meijuan since its establishment, and have been developed in cooperation with the best scientific research team in China. After three years of heavy work, they naturally have fruitful results and have now developed to the third generation.

It is probably too good to use carbon fiber material to replace steel strips. The strength and toughness of carbon fiber are 200 times that of ordinary steel, and even the best alloy steel cannot be compared with it.

There are the best materials and the most precise machining technology, so you know that the CVT automatic transmission, which seems to be difficult in domestic automobile companies, was developed by Miao Wei's team in less than a year.

This is the benefit of solid basic technology. All technological research and development are almost natural.

Although the research and development time is not long, this CVT continuously variable transmission specially equipped for small-displacement cars has excellent performance. Its petite body can even withstand the powerful torque of a 3.5-liter car with a displacement of up to 185 Nm.

It is used in small-displacement vehicles, but it also produces an unexpected benefit, that is, it can't be bad no matter how you make it. It's simply a rebirth of a super strong man.

In addition, because it can withstand greater torque, it is not a four-speed transmission like Toyota Aisin, but a fifth gear with an additional high-speed gear, so the driving experience is better.

Miao Wei’s team is now studying automotive chassis technology. In a car, in addition to powertrain, it is the most difficult to count chassis.

A chassis is not just a shelf, it is a complex integrating various system technologies. An advanced chassis usually takes 3 to 5 years of research and development, and can only be developed by foreign automobile giants.

According to conventional methods, Dolphin Technology will not only violate the invention patents of foreign automobile giants, but also find it difficult to surpass those foreign automobile companies that have been immersed in the end disk research for decades.

This is a dead end. Since it cannot be done according to the conventional method, the only way is to seek innovation and change.

Everyone should remember the new shock-absorbing wheels of bicycles invented by Liu Meijuan three years ago! That kind of black technology is also applicable to car wheels.

Because of this, in the past three years, several automobile companies have come to discuss the purchase of patent authorization, but Wang Yong did not agree. The purpose is to use this unique technology for your own use. It should not be too good to use it in automobile chassis shock absorption technology.

Of course, the shock-absorbing wheel hub used on the car chassis has made considerable technical improvements. It does not only passive shock absorption like a bicycle, but has active shock absorption technology like a gas spring. It controls the air pressure strength of each telescopic rod on the wheel hub through an MCU industrial control chip to actively resist and unload the impact force brought by various road conditions of the vehicle.

The advantage of this technology is that it can walk on flat ground, whether in cities or off-road, and ensures that the car is always in the smoothest state.

With this awesome technology, it is much easier for Miao Wei’s team to develop a chassis. The body and the chassis are directly connected with steel. There is no McPherson shock absorption, steel plate shock absorption or air shock absorption. All shock absorption tasks are handed over to four universal shock absorption wheels, which is so simple and crude.

The steering wheel booster uses the latest electric booster technology.

The steering system has gone through four stages of development: from the initial mechanical steering system (MS) to the hydraulic power steering system (HPS), and then the electronically controlled hydraulic power steering system (EHPS) and electric power steering system (EPS).

Among them, the latest electric power steering system has many advantages such as simple structure, energy saving and environmental protection, stability and reliability.

This latest technology was originally developed by Honda in 1990, but they used gear transmission power-assist technology.

Miao Wei's team made a small change, using the carbon fiber tooth belt technology in the CVT transmission to avoid Honda's invention patents well.

Other technologies such as engine monitoring, vehicle speed monitoring and MCU control unit system integration are the same as the previous generation of electronic hydraulic assist technology. That was the technology of the 1980s and has long passed the patent protection period.

So Miao Wei's team copied the matter directly.

In addition, the most important thing about the chassis is safety system technology, such as brake system, car anti-slip system, vehicle stability system, EBS anti-lock system, etc.

Of course, there are more advanced vehicle automatic parking systems, radar sensing and anti-collision technology, etc.

In short, the technology of automobile chassis system is very complex. Although we can learn from other people's technology, it is another to know that doing it is one thing, and trying to do it well is another.

Not to mention it too much, just matching and adjusting the power of an engine and transmission, it will take a year and a half.

As everyone knows, Liu Meijuan’s requirements are very strict, and her starting requirements are comparable to those of the international advanced level.

Therefore, Miao Wei's team still has a long way to go in chassis research and development, otherwise it would be impossible for Liu Meijuan to pass the review.

Of course, Miao Wei’s team is not fighting alone. For those who are in the field of embedded system research and development, they can get strong technical support from the System Application Software Research Institute.

During these three long years, in addition to Miao Wei’s team, the biggest development of major software research institutes are the ones.

Yes, the cloud operating system, or the Internet of Things, has finally been fully tried within the company after several years of bumps and bumps.

The reason why it is not commercialized is not that it is not good enough, but because there is too little content on the Internet of Things and is far from comparable to the international Internet.

In addition, so far, the company does not have the ability to manufacture high-performance chips on a large scale, so it still has to be low-key and tolerant.

I can do a lot in three years, but it seems too short to use it to develop software with complex functions.

Software and hardware have always been two difficult hard bones in the field of electronic computers.

For example, those tool software with complex functions and priced at tens of millions will be difficult to develop even a software successfully in three years.
