"Come on, Carl, my friend, I have already drawn this blueprint." The next day, Qin Shaoyou took the blueprint and ran to Karl: "Give me the 200 million yuan as soon as possible."

Qin Shaoyou also pointed to this fund to build a turbocharger factory, so he was very anxious.

After finishing speaking, Qin Shaoyou saw Carl's red eyes and was extremely curious: "Hey, what's going on? Didn't you have a good rest yesterday?"

Then, Qin Shaoyou smelled it again: "What's the smell on you? You haven't showered for a few days? You don't work overtime, do you? You Germans, you still work overtime?"

"Yes, this is what we call doing as Romans do." Carl said, "Qin, we have encountered many problems."

"Really?" Qin Shaoyou asked: "What's the problem? You can tell me and let me listen."

"First of all, our platform lacks a suitable automatic transmission. Although it is not very useful, if there is no such automatic transmission, then our platform cannot achieve sufficient compatibility and variability. said Carl.

In this era, Volkswagen’s cars are still mainly equipped with longitudinal engines, and Santana has this kind of layout. If they still have a vertical platform, then they have an optional three-speed automatic transmission, but the horizontal platform is gone. !

"Are you trying to find a suitable horizontal automatic transmission?" Qin Shaoyou said: "Don't just focus on ZF in your country, you can look at Aisin from the East."

Speaking of AT transmissions, the two giants are ZF and Aisin, both of which can provide qualified automatic transmissions to other automakers.

As for Volkswagen, it has always relied on buying.

After all, manual transmission is popular in the European market, and the proportion of automatic transmission is very small. An old lady in her [-]s and [-]s can play with manual transmission.Volkswagen only needs to outsource a small batch.

The horizontal platform is indeed a trouble, but at this time, Aisin already has a mature 4at gearbox with a horizontal platform, and has even begun to develop a 6at gearbox with more gears.

Qin Shaoyou said slowly: "Aisin Seiki is also an established company. Their 4at transverse gearbox is very reliable. It is said that they have begun to develop 6at. The installation method is the same and can be interchanged. Your platform can match their transmission. In this way, we can guarantee that we will not fall behind in the future.”

friend?Friends can also be fooled!When they are deceived by Aisin, Qin Shaoyou can sell his mature dual-clutch gearbox. If Volkswagen gives up its vigilance and does not develop its own gearbox, then it can supply them completely by itself in the future. A huge deal.

"Aisin? Six-speed gearbox?" Carl's eyes lit up: "It seems that we should turn our attention to the East more."

"Are there any other problems?" Qin Shaoyou continued to ask, he had to give them some more ideas, so that they could finalize the project as soon as possible.

"Other problems..." Carl said: "Take the rear suspension system of a car as an example. It can have multi-link suspension or torsion beam suspension. The former is more comfortable, while the latter saves space. If we make a If there is a platform, then the reserved space must be large enough, so that the space for the suitcase is small.”

"What kind of problem is this, just leave a large space." Qin Shaoyou said.

The torsion beam is a beam that looks like a shoulder pole, so it is also called a pole beam. The multi-link has several tie rods to control the posture of the rear wheels. The former is simple, while the latter has good performance, but takes up a lot of space.

Therefore, when talking about the advantages and disadvantages of these rear suspensions, some people will always say that the pole beam can save space.

Really save?

It depends on whether it is the only one that uses torsion beams. If it is equipped with low torsion beams and high with multi-links, then there is no doubt that there must be enough space inside.For a model, the shell is the same, and will not be changed for different suspensions.Definitely have to stay big beforehand.Therefore, the so-called saving space is nonsense.

"Are there any questions?" Qin Shaoyou continued to ask.

"There is also the problem of the wiring harness of the car. If we engage in modularization, should the wiring harness of the car also be unified?" Carl continued to ask.

When the car was first manufactured, there was no need to think about this kind of problem. Even the gas lamp was used for the light. There was no circuit at all. The ignition circuit of the gasoline engine could be cycled by itself, and there was no button in the cab.

However, with the development of technology, the circuits inside the car are becoming more and more complex. Turning lights, brake lights, fog lights, wipers, etc., the wiring harness is getting bigger and bigger. After all, a light needs a wire, which is still in the The whole vehicle is grounded on the basis of a line.

Up to now, in high-end cars, the wiring harness is even thicker, there are electric lifting glass, electric folding and adjusting rearview mirrors, and even electric seats.

This also means that the wiring harness inside is getting thicker and thicker.

Now, they want to engage in modularization, how to solve the problem of the wiring harness?Can a unified modular wiring harness be used?

When Qin Shaoyou just introduced him to Carl before, Carl felt that his eyes lit up, but when he detailed all these things, he would find that various problems emerged one after another.

"This problem is also easy to solve." Qin Shaoyou said: "Bus technology can be used."

"Bus?" Carlton was taken aback for a moment: "Qin, I admire your profound knowledge. How do you know so many things?"

Every time a new type of electrical equipment is added, a special circuit must be added. In this way, the circuit of the car will become more and more large. How can this problem be solved?

That, of course, is the high-tech bus technology.

If you give an example, it is like the Internet. If there is no Internet communication protocol, then, to communicate between computer a and computer b, a cable must be connected between computer ab. And b, b and c continue to connect lines, as the number of computers increases, these lines will grow rapidly.With a specific agreement, as long as a network cable, data can be transmitted between each other.

In order to solve more and more problems of automotive electrical equipment, in 1986, German electrical company Bosch first developed a communication protocol for automobiles.Standardized by iso11898 and iso11519, various electronic devices on the car can be connected together as long as they pass through this bus.Specifically, for turning on the turn signal, three wires need to be connected from the turn signal switch, one is input wire, two output wires, one left and one right.

These two wires are divided into two strands, forward and backward respectively. These lines transmit current to the turn signal bulb, and form a loop through grounding, and the bulb lights up.

For the front of the car, in addition to the turn signals, there are also headlights, small lights, fog lights, double flashing, etc., each light needs a line, so a bundle of thick lines is required .

What if bus technology is used?

For the front, there are only two wires, one is the power supply, which leads to various electrical appliances, and the other is the transmission line of the bus, which is connected to the controllers of each light.When the turn switch is turned on, the switch sends a signal to the bus. After the signal is delivered, the turn signal controller acts and the control circuit is connected.

What are the benefits of this?

For example, if someone forgets to turn on the turn signal and turns the steering wheel, then the system detects that the steering wheel has begun to turn, and can automatically control the turn signal to turn on. Although it does not meet the traffic regulations that require the turn signal to be turned on in advance, it is still a remedy for the dead .

For another example, if the car collides, the system will automatically turn on the circuit of the double flashing lights to remind the vehicles behind.

Therefore, bus technology is a high-tech product that will bring great convenience to users. In the later stage, it can even control more, such as the electric steering wheel. If you change the direction without turning on the turn signal, the bus can transmit signal, and then change the steering wheel back.

Karl was extremely excited. The problems they couldn't think of about their sister were easily solved by Qin Shaoyou.This report can be completed as soon as possible.

"Okay, it's solved again, let's move on to the next one."

Qin Shaoyou is in a hurry!He is looking forward to getting the 200 million in his hands as soon as possible.

After solving more than a dozen key problems for Carl, Carl nodded with satisfaction: "Qin, thank you for your help, we have solved all the problems, by the way, you just said that you have drawn the design diagram?"

Now Carl is in the mood to look at the design drawings. When he picked up the design drawings from Qin Shaoyou's hand, Carl was shocked immediately.

"Qin, you are simply a master-level designer!"

This design drawing is more than ten years beyond this era, and it will naturally give people a special feeling when it is taken out now. The overall lines of the car are very smooth, and together they outline a modern car. Several horizontal bars, The vw logo is properly embellished in it, which looks so natural and harmonious.

Every car designed by Qin Shaoyou is amazing, and Karl admires it very much: "This design drawing is worth 200 million yuan. I will fax this design drawing back, and please pay the design fee for you over there." .”

Qin Shaoyou nodded, this is not too bad, since this is the case, then he might as well say more: "This design of mine has reached a new height in car design, so the designers in Wolfsburg , as long as I make a little modification on my design drawing, for example, if the butt is removed, it will be a new generation of Golf. Yes, you can get a whole lineup."

Volkswagen only has one car, the Golf, but now, in Qin Shaoyou's place, this car has become a sedan in his hand. After all, hatchbacks without buttocks are not valued in China now.

Carl's eyes brightened: "This is also the benefit of platform modularization, Qin, I am already full of confidence in this project!"

Carl said while holding the design drawing of this car, full of praise, suddenly, he thought of something: "Qin, this car needs a famous name, what do you think?"

Qin Shaoyou nodded: "Of course, its English name is lavida."

Qin Shaoyou said while writing his name next to the design drawing.

Lavida is a typical Spanish word meaning life, life and hope.

"Yes, using this word can represent the unrestrained and dynamic life force and the fun-filled life form. This is the life potential bursting from the depths of the heart, full of passion and motivation to move forward to a better life." Carl said with emotion .

"If this car is to be sold in our country, we have to give it a Chinese name, which is similar in pronunciation to the English name and has a certain meaning." Qin Shaoyou continued: "How about calling it Lavida?"

You can't perform too well, you have to think about it before you say it, and the words that come out of your mouth are simply gods.

Naming a car is very particular. The typical negative is Kia. In a certain place, when someone is buried and the coffin is lifted, the person at the front will shout: "Get up!" So, this place , Kia is not sold.

Another example is ds, which comes from the word deesse in French, which means goddess in Chinese, so it is good to hear this name, but after it was made in China, the transliterated name became Diesse, which directly pulled the goddess from the sky It landed, and landed face first.What's more, seeing that car logo makes people think of **, so it won't be popular anymore.

Qin Shaoyou is not a superstition, but a summary of real experience.

The Chinese name Lavida is also very good, Minglang Yidong fits the positioning of this car.

"Qin, the name you chose is very good!" Carl agreed.

"Then, when you apply, give me an extra 20 yuan for the naming fee, isn't that too much?" Qin Shaoyou asked.

Carl nodded without hesitation: "Yes!"

Sure enough, dealing with foreigners is a pleasure, another 20 more!Qin Shaoyou was delighted.

At this moment, the pager on Qin Shaoyou's waist rang, looking at the number displayed on it, Qin Shaoyou was shocked immediately, the call from the University of Science and Technology, could it be that there has been a result over there?

"My old friend, I still have some things to do, so I have to go." Qin Shaoyou said.

"Well, don't worry, the design fee and naming fee for your application will come down soon." Carl said.

Qin Shaoyou had disappeared at the door.
