"Qin Gong, a software error may also cause hardware damage, such as the impact of gear shifting causing the gear to collapse." Masao Hattori said.

"That's because the strength of the gears is not enough, or the metal is fatigued, which is a hardware problem." Qin Shaoyou said: "Your obstruction makes us doubt your sincerity. We just signed the contract, and you think that this Can you deal with us? Your Excellency Hattori, I decided to buy [-] gearboxes because of your sincerity. Now, if you are like this, then our agreement will be invalidated. It is your reason, so , according to the contract, you should compensate us for the loss!"

"Qin Gong, your words are too rude." Taro Taro was about to get angry again.

"Why, is this going to change face?" Qin Shaoyou said: "We will accompany you to the international court to file a lawsuit!"

Seeing that there was going to be a stalemate again, Masao Hattori could only back down: "Okay, I can let you calibrate the program, but the program after calibration must be checked by our technicians to confirm that there is no problem, otherwise, we will not Warranty provided."

Qin Shaoyou glanced at the other party: "Okay. I believe that your technicians will not judge the deer as a horse. At that time, if you are still picky, then we will load it into the car and send it to the international community to evaluate how our calibration procedures are. We believe that , there are still reasonable places in this world.”

Hattori Masao frowned, and the other party directly punctured their thoughts, but now they seemed to have no other choice.

"According to the contract, deliver five thousand gearboxes to us at one time." Qin Shaoyou continued.

"Qin Gong, this doesn't seem to be in line with the convention, and our production capacity is also limited."

"Your Excellency Hattori, to be honest, after what happened just now, I no longer believe in you. The five thousand gearboxes are handed over to us at one time, and we can still accept the payment and delivery. In the future, you may They will use the excuse of limited production capacity, factory power outages, etc. to delay delivery or ask for a price increase, so we are a one-shot deal, understand?"

Masao Hattori's expression turned ugly: "Qin Gong, I think you have misunderstood us."

"Okay, then show your sincerity and prove that this is a misunderstanding."

This transaction cannot be regarded as happy.

The technicians present were a little angry when these islanders were sent away.

"Qin Gong, these islanders are too bad!" Pang Damin said through gritted teeth.

"Yeah, we don't have anything similar, so we can only buy from them. Of course, they will make things difficult for us. They can have many tricks to get us to invest more." Qin Shaoyou said.

"Could it be that they still have tricks?" Elder He also asked from the side.

It costs so much money just for program calibration, which fully shows that the other party is unreliable.

"Yeah, they haven't agreed to give us the program source code yet!" Qin Shaoyou said, "It's just that I didn't bother to mention it just now."

"Yeah, without the source code of the program, how can we modify it?" Pang Damin was also anxious.

Speaking of the program, it seems very high-level. In fact, it is the same as learning a foreign language. It is a language for dealing with machines. It tells the machine what to do and how to deal with problems. These are all written in lines of code.

However, this code is just a program fragment. If it wants to execute, it must be compiled and turned into something recognized by the machine, and then packaged together to become an executable program.

The electronic control part of the automatic transmission is controlled by a special chip, which is equivalent to a microcomputer, or a single-chip microcomputer.

This program needs to be written on the computer, and then input (the proper term is called burning) into the control chip of the automatic transmission. Every time an upgrade is made, a new program is rewritten.

So, even if they got [-] AT gearboxes, what they have is only the original executable program that has been burned into it, not the source code of the program. How can they modify it?

It's like everyone is using the windows system, why has no one modified it?It cannot be modified. What you get is an executable program, not the source code of the Windows system.If you want to play by yourself, then use linux. The source code is public and you can modify it yourself. As long as you have the ability, after modification, you can compile it into a new system and use it yourself.

"That's right, the devil must hand over the source code!" Others said.
The source code of the program needs to be translated into a language that the machine can understand through a compiler, that is, a line of code consisting of 0 and 1, and decompilation is to reverse this process, and then translate from 0 and 1 into a line of program code.

It's just that most people don't use it.

"Can it still be decompiled?" Everyone was surprised for a while.

"Yes, it's just that the decompiled code has no comments, and may even be confusing. We need to analyze it carefully."

"We're not afraid of this." Pang Damin immediately patted his chest and assured: "Leave this kind of thing to us!"

"Qin Gong, since they have such evil intentions, why do we still use them?" Someone said angrily.

"Well, of course it's because it's cheap enough."

One thousand dollars for a 4at gearbox that can withstand high torque is not expensive at all!If it weren't for the cheap price, how could Qin Shaoyou have been arguing with the other party for so long?

Our side doesn’t have one yet, so we can only make a transition. As for the GM automatic transmission, it’s really not as easy to use as the islanders. Whether it’s 4at or 6at, the island’s gearbox is really unique.

The only thing that can defeat the islanders is the dual clutch, but well, that thing can't be taken out immediately.

Qin Shaoyou is waiting.

At the same time, on the other side, Masao Hattori and Taro Ono got into the car, and they were also very unconvinced.

"Your Excellency Hattori, this is the most useless deal we have ever done. We would rather not have this deal than let them take advantage of it." Ono Taro said.

"Ohno-kun, you are too far from your grandfather." Hattori Masao said: "In business, you must not be in a hurry. Take your time. After they receive [-] gearboxes, they still cannot complete the calibration work. At that time, you still have to come and beg us.”

"why?"

"Because they don't have the source code of the program, if they want it, our core secrets need at least 500 million."

Ono Taro reacted, with a smile on his face: "Yaoxi!"

half a month later.

"Qin Gong, let me introduce you. This is Jiro Aso, a technician from our Aisin AW company. He will be responsible for checking your gearbox program calibration." This time, Masao Hattori did not come, only Taro Ohno, anyway. It was a stalemate, at worst, it would break up, anyway, the business had already been done, at worst, it would leave a mess for Phoenix Che, and in the end, the other party had to invite them back.

Ono Taro spoke in anger, triumphantly.

"Your Excellency Jiro Aso, you have worked hard all the way." Qin Shaoyou said: "Please stay in the hotel, and please come over after our program is calibrated."

Aso Jiro was a little curious: "Is there nothing wrong with you?"

"Of course not. Please don't interfere with our operations. After all, this involves our business secrets." Qin Shaoyou still spoke very politely.

Ono Taro was very angry, what is going on?You actually said it was the other party's business secret?The other party calibrated his own gearbox, but he didn't let him see it?Isn't this too ignorant of oneself?

"You can continue to study how to change 4at to 6at in the hotel." Qin Shaoyou continued: "It is very difficult for you."

"What did you say?" Ono Taro was very dissatisfied: "For our technicians, adding two gears is a small difficulty!"

"If it is a vertical gearbox, there is no requirement for the length of the gearbox. Of course, it is no problem. However, it is not so easy to install a horizontal gearbox. Although only one gear is added, the internal structure of the gearbox has to be It's twice as complicated." Qin Shaoyou glanced at Aso Jiro: "You have to speed up, if the patent is registered by someone else, it will be even more difficult for you."

Aso Jiro's face became ugly.

Coming here, Aso Jiro really wanted to put on airs as a technician. After all, the technology of their island country is the most powerful. This point has never changed in his heart, but now, if the other party says a word, It took a blow to his confidence.

The other party was quite right.

Aisin Warner developed the horizontal 84at gearbox in 4. In 87, Aisin Warner and BorgWarner terminated the joint venture relationship. Development of a six-speed gearbox.

However, until now, the six-speed gearbox has not been built because it is too difficult.

To put it simply, just add planetary gears. However, if only planetary gears are added, the gearbox will definitely become longer. For a horizontal gearbox, this is simply a nightmare.

They have thought of many ways, but they still can't perfect it, and the difficulty is very great.

Now, the other party actually explained the difficulty and complexity in one word, which made Jiro Aso very curious.

But now, he didn't ask any more questions. Since the other party asked him to avoid it, he just avoided it. There will always be the other party who will come back to beg him.

With this in mind, Jiro Aso and Taro Ohno left, and Qin Shaoyou waved to his subordinates: "Take this gearbox to our laboratory and start working immediately!"

"Brother Shaoyou, can we do it ourselves?" Xia Miaomiao's voice came.

Xia Miaomiao and Su Mengyao also came together. After all, they had to match the gearbox of the island country, and they also hoped to learn some experience from it. However, unlike what Qin Shaoyou said, the island people left, and they were the only ones left to do it themselves.

Can it match?

Qin Shaoyou smiled: "Miao Miao, when have you ever seen me do something I'm not sure about? Since I want to do it, I must be sure."

"Yes, there is no Qin Gong who can't." Su Mengyao showed her small canine teeth and smiled happily.

"Let's go, plug in the cable first, copy the program inside, and then reverse compile." Qin Shaoyou said.

Of course, Qin Shaoyou didn't need to do this, Pang Pangmin and others had already plugged the data cable in quickly and started to operate.

three hours later.

Qin Shaoyou opened the code file.

"Wow, so many!" Looking at the tens of thousands of codes, everyone couldn't help but sigh with emotion.

"It's only tens of thousands. When it comes to 6at gearboxes, it's hundreds of thousands. With 8at, it's millions. With the increase of gears, the complexity of the program increases exponentially." Qin Shaoyou said , fingers jumping on the keyboard.

"Qin Gong, are you adding notes to us?"

"Qin Gong, the first time you read it, you know what these are for?"

Everyone was stunned.

Qin Shaoyou smiled.

Qin Shaoyou really doesn’t understand the codes of other gearboxes, but Aisin 4at gearbox, this is a model that Qin Shaoyou has been in contact with for more than ten years, even if it has not been decompiled, Qin Shaoyou can write it alone Done, it's just a waste of time.

This gearbox is definitely an evergreen tree. It has been used from the 80s to 2020. It is even used by some car companies, and there are some tall sayings. The 4at gearbox has a simple structure, is not easy to break, and is easy to replace. Block smoothly!

In terms of smoothness, it really is. After all, the more gears there are, the more frequently the gears are changed. At the moment of gear switching, there are always some frustrations.Especially when you stop and go in the urban area, the gearbox with many gears will change back and forth between the first, second and third gears, which will naturally cause setbacks.

There is no need for 4at. When you stop and go, you only need to engage the first gear, and the speed ratio of the first gear can be slightly lower. (For a simple explanation, it is equivalent to the second gear of a six-speed gearbox.) In this way, when a large torque is required, the torque converter in front of the automatic transmission is used to achieve it, and when the speed needs to be increased, the accelerator is increased , until it is too big to go to the second gear, which greatly reduces the frequency of gear switching, and of course it is smooth.

Another consequence of smoothness is fuel consumption.

When the automatic transmission first appeared, there were only two gears, and the torque converter was used to reduce the speed and increase the torque, but the fuel consumption was astonishingly high.

The current four-speed gearbox also has this disadvantage. You can’t have both. When driving on the highway, the speed ratio of the 4at gearbox is not suitable, and the engine speed cannot be reduced, so the car will naturally consume more fuel.

Of course, the fuel consumption is also compared with the advanced models of later generations. As far as the current situation is concerned, there is no obvious difference.
