big country car

Karl felt that his brain was not enough.

He knew that Qin Shaoyou was very powerful and had a high vision, but he never thought that Qin Shaoyou had such lofty ambitions. The first car he wanted to build was actually comparable to

a flush or even beyond!

Even manufacturers at the level of Mercedes-Benz and BMW are developing this kind of high-end electronic stability program. The ancient East has not yet completed the localization of Santana, so it dares to pursue this high-end system?

After being shocked, Carl said with emotion: "Qin, your idea is too powerful, but it is not easy to build this kind of system!"

"What's not easy." Qin Shaoyou curled his lips there: "This system, first of all, must monitor changes in the body. In addition to the wheel speed sensor of the ABS system, other systems are also required. For example, we need A steering sensor is added to the steering wheel to monitor the steering angle of the steering wheel. In the system control unit, a side slip sensor and a lateral acceleration sensor are added to monitor the state of the car body rotating around the vertical axis and the centrifugal force of the car when turning. In addition Some accelerator and brake pedal sensors, etc., so that the motion status of the entire body can be collected.”

Speaking from Qin Shaoyou's mouth, it seems that there is no difficulty. After all, these components can be bought in the international market, and there may be domestic products in the later stage.

"The most important thing is the program." Carl said: "You purchased those things, but the hardware system is complete. To effectively process so much data, you need to build a special model."

As an automotive engineer, Carl speaks directly to the most critical things.

"Yes, the program is the most important thing. We plan to use a group of college students to do it. I have already made a model." Qin Shaoyou said.

Qin Shaoyou is a hardware engineer who takes all software and hardware, and is naturally very familiar with this high-end electronic stability system.

In later generations, all kinds of cars are using this system, but most of them use Bosch system, Mercedes-Benz, Volkswagen, Audi, Citroen, Peugeot, Hyundai, etc., according to Bosch, are called esp, which is electronic stability progra Abbreviation for stabilization program.When various media commented, they also used this as an abbreviation.

When it comes to BMW, you can’t find esp, because the system of BMW and Mazda is called dsc. Similarly, Honda is called vsa, Toyota is called vsc, and Nissan is called vdc.Regardless of the name, the fundamentals are the same.

Bosch provides the most, even Tesla's much-criticized braking problem, the electronic braking system, is also provided by Bosch, but Tesla has rewritten many of the codes. (Bosch is really good)

In the later stage, this system has already been compulsorily assembled by the state, and those who are unable to develop it can only purchase Bosch. Moreover, it can be boasted that it is the first generation of Bosch.

I use the 9.3 generation, and the others only use the 8.2 generation, so mine is the strongest!

Of course this is not the case.

Any car has its own unique configuration, different wheelbase, different steering force, different wheel models, etc., because these are all different, so the public version program provided by Bosch must be optimized. .

Some people like to buy low-end models, such as electric seats, electric steering wheels, and 360 panoramic views, all of which can be retrofitted, which are cheaper than your original ones!Certain things cannot be post-added, and esp is one of them.

Qin Shaoyou had worked hard on this system in his previous life. In the end, he even rewrote all the source code and established his own special data model. Therefore, he has thoroughly understood this system.

As long as he gets the hardware, he can solve the software problem, and it is specially matched to the car at hand!

Of course, this system needs a lot of data support, continuous testing, and continuous optimization. It will take several years to mature. Even if it has not surpassed Mercedes-Benz and is at the same time as Mercedes-Benz, it can also show that the Phoenix car is taller. .

"Qin, your ability is really admirable. If Mercedes-Benz finds out, it will definitely come to poach you." Carl said.

Qin Shaoyou smiled: "Really? Then I must wait, and then refuse their invitation, so that my worth will be even higher."

Carl was speechless for a while.

The inspection of the project was over, and Carl left with emotion. Before leaving, he couldn't help saying: "Qin, this car has aroused my great interest. If possible, I also want to join in the name of a private person. "

Qin Shaoyou frowned, this is not very good, is it?

"Especially, in the final debugging stage of the car, you will encounter many problems, and your experience is still too little." Carl said, "Maybe I can help."

If it is the final debugging stage, it can still be considered, so Qin Shaoyou nodded: "Okay."

Carl left, but the news that he came to Phoenix Qin SUV R&D Center for inspection spread quickly.

Technology Department.

"Xiao Wang, have you heard? The Germans have seen the bottom of the Phoenix car. This is absolutely dereliction of duty. How can such a confidential research and development project be seen by foreigners?" Zhang Changjiang and the people around him murmured Goo.

The technician named Xiao Wang glanced at him: "Mr. Zhang, we are not in charge of that part, so don't worry about it."

"How can you not worry about it? The factory is becoming more and more outrageous. In the past, the security department in the factory was so powerful. This kind of secret unit and project was strictly sealed off. Now? Hmph, it is under research and development. The project can be viewed by anyone at random.”

"Yeah, compared with before, the changes in the factory are really big." Another technician spoke, and what this person said successfully aroused Zhang Changjiang's interest. He just wanted to continue to sell his own set theory, but heard the other party continue to say: "If you want to talk about reform, you still have to look at the young people. Qin Gong is courageous. Those who are idle are all transferred away."

Zhang Changjiang's complexion changed: "Zhao, what do you mean by that? Are you saying that I'm too busy talking?"

Zhang Changjiang still has self-knowledge.This rhetorical question is loud.

Gao Zhongzhong looked over: "It's working time now, put your mind on work, in our technical department, there will be competition in the future, and the backward technicians may also be diverted away."

Zhang Changjiang didn't speak, but he was secretly angry.He missed the days when Chen Dongqiang was here.

The present day makes him feel very difficult.

In the midst of hardships, the days passed day by day, when the National Day, the Santana station wagon finally went offline.

At the end of the production line, a large group of people stood, including factory leaders, German consultants, and clerks from the Volkswagen 4S store.

The silver Santana station wagon still looks quite beautiful, with a big red flower on the front of the car, beaming with joy.

There were also some reporters who came to join in the fun, set up their own camera tripods at the end of the production line, and waited.

Finally, the Santana station wagon drove over, click click click, the flash of the camera was jumping, leaving precious shots one after another.

"Comrades, consultants, workers, and friends from the press, our Santana station wagon has finally rolled off the production line on the day of National Day, which is worth celebrating. There is a new model on our product line. We Looking forward to seeing this kind of car running on the land of the motherland, and contributing to the economic construction of our motherland!"

Everyone applauded.

Karl was also very happy. He watched the car start slowly and was excited.

The travel version is out, and the Santana 2000 will also be out. The running-in of this production line is getting better and better, and the output is constantly increasing. This year, Volkswagen's income will definitely be very dazzling.In the future, it is possible to surpass the Brazilian public.

Zhang Lijun waited excitedly. When the car stopped, he jumped into the cab. This car will be sold in their 4s shop first, which is enough to show the factory's care for the 4s shop.

He sat inside, looked at the familiar instruments, and then looked at the rear. The spacious space was enough to meet the needs of special users.

He started the car, started it slowly, and left the production line in front of everyone's eyes, and behind him, cars of the same model drove out one after another.

Zhang Lijun drove the car to the store, and stopped at the most conspicuous place in the exhibition hall.

"What kind of car is this?" Customers have already gathered around.

"This is the travel version of Santana, the price is 23." Zhang Lijun said: "No one has ordered it yet. If you want it, you don't need to queue up. You can pick it up today. There are ten cars in total. Pay first, first served!"

Most of the customers who come to buy a car need to make a deposit and wait in line. After all, the factory’s production capacity can’t keep up. Now these Santana travel versions are sold as existing cars. In Zhang Lijun’s view, they should be sold today light.

However, what greeted him was a pair of questioning eyes.

"What, 23? It's tens of thousands more expensive than the ordinary Santana!"

"That's right, it's still a buttless, is this a car?"

"From the back, it looks like a coffin."

As soon as these words came out, Zhang Lijun's face completely darkened, can you say that?

However, if you look at it from the back, it really looks like... stop, stop, you can't have this kind of thinking.

Zhang Lijun stood on the roof. Anyway, the current car is quite strong, so there is nothing to worry about.

"Everyone, this is the most popular station wagon in Europe. It can meet the travel needs of a family. It is our first choice in China. Compared with the ordinary Santana, it can hold more goods, and a family of seven can travel!"

Zhang Lijun had already prepared these arguments, but the people below seemed to not buy it!

The eyes of those people told Zhang Lijun that he would rather wait in line for Santana, even if it took a few months or even half a year, than buy this car.

There were ten quotas, but none were sold!

At the very beginning, the salesmen were very enthusiastic. For all the customers who entered the store, they would recommend the travel version of Santana first. He drooped his face.

Is this a car?

One day, two days, three days, as wave after wave of customers shook their heads, the enthusiasm of the salesmen was also consumed. Zhang Lijun looked at the travel version of Santana in the c position, his head was extremely big.

There is no other way, let's go to Qin Shaoyou again, no matter what problems you encounter, Qin Shaoyou can help you solve them.

At the end of October, the city of S was getting colder day by day, and the people in the Qin R&D Center were still very hot. Countless master craftsmen, beating and tapping, had already started making the outer shell of the car.

The prototype cars in the early stage were all handmade. These master craftsmen are the most familiar. With the experience of last time, they can also beat the steel plate into a specific shape according to the drawings and clay models.

"Qin Gong, I'm a little surprised about this car roof. Why is there an extra rib in the middle? Even Santana has never seen such a design." A master craftsman asked Qin Shaoyou with the blueprint.

The regular car roof is a piece of iron sheet, which is directly stamped and formed, and the bottom is connected with the four pillars abcd. The inside of the iron sheet is the interior.

Now, Qin Shaoyou added an extra rib to the roof, which looked a little weird.

"Oh, this is because we will cut this place in the future to make a panoramic sunroof. In order to increase the strength of the roof, we added an additional rib here."

"Skylight?"

Few people will follow Qin Shaoyou's train of thought.

The car sunroof is nothing new. When the car first came out, it was a convertible, that is, a panoramic sunroof. Later, it began to have a cover.

The 1941 Lincoln Continental was the first car with a recorded panoramic sunroof.

But that was just an innovation. For a long time, ordinary cars did not have sunroofs. Everyone was surprised when Qin Shaoyou proposed to install a sunroof for this kind of car.

He Jiaxuan, who had been following along to join in the fun, suddenly thought of something: "Is it a parade car?"

It is difficult for others to think of this, but He Jiaxuan is different. He Jiaxuan subconsciously thought of this kind of vehicle. This is what they are most looking forward to, and it has never been successful.

The parade cars will always belong to FAW's Hongqi cars, they do not have that qualification.

Now, when Qin Shaoyou talked about the sunroof, which means opening a window on the roof of the car, he thought of the military parade.

Parade car?Qin Shaoyou shook his head. This kind of car, which reflects the dignity of a country, can only be a red flag. Of course, they can also fight for it, but not now.

In the future, get a large-displacement engine, build a top-end car, and bid for a parade car with FAW Hongqi. Even if it fails, you can spur FAW to pay attention to technological development and make progress in the competition.

At this moment, Zhang Lijun walked in.

"Mr. He, you're here too, Qin Gong, I'm looking for you..."

Seeing the seriousness on Zhang Lijun's face, Qin Shaoyou nodded: "Brother Zhang, let's go into the office and talk."
