Wang Xu spent the afternoon struggling at Liu Yuchen's house, and kept helping Liu Yuchen find all kinds of motherboard information.

I don’t know how many auto repair forums I searched for before I found the information.

But when Liu Yuchen looked, most of them were basic motherboards, and they were not very detailed.

It is naturally impossible for Liu Yuchen to create a motherboard out of thin air. After all, she cannot add some unnecessary features to a car.

Moreover, she doesn't know much about the various functions of the car.

This gave Liu Yuchen a headache. He sat in front of the computer and couldn't design a motherboard picture.

"Have you figured it out yet? Don't worry, come and eat some fruit first!"

Wang Xu brought the plate in. Naturally, the fruit on the plate was cut, but it was a little ugly.

"This is not a question of whether to be anxious or not. The main reason is that I don't understand the car!" Liu Yuchen looked at Wang Xu with some disgust: "Why is it so ugly that you cut it!"

No matter how much I said it, I still picked up a slice of apple and ate it.

"I would have a car-knowing person around me!"

"Why don't you go and find Lao Chen? Lao Chen must know the car!" Wang Xu said with a smile.

"If you say that, Old Chen can do design drawings by himself! Why ask me for help?" Liu Yuchen rolled his eyes: "Teacher is training me, do you understand?"

“emmm…yes, yes…”

Actually, I think Lao Chen treats you as a coolie.

Wang Xu thought so, and suddenly clapped his hands and said, "Yes! Look for Li Yiyang!"

"Li Yiyang?" Liu Yuchen was stunned: "Why are you looking for him? Does he know the car?"

"It should be understood!" Wang Xu scratched his head: "I remember he had liked to talk about various cars before, such as four-cylinders, engines, etc., and autonomous driving. Anyway, it sounds very powerful. Why don't I call him and ask him, and I have a good relationship with him!"

"Okay, ask!" Liu Yuchen nodded.

Wang Xu quickly called Li Yiyang. As soon as the phone was answered, Wang Xu said, "Li Yiyang, I'll ask you for help."

"What?"

Wang Xu hurriedly said: "We need a professional car-knowledgeable person to do a favor!"

"Then you are looking for the right person, but, are there any benefits for me?"

Wang Xu was stunned: "Then what benefits do you want?"

"I still owe Lao Chen a five thousand-word review..."

Wang Xu was shocked: "Damn it! Can you still owe it?"

"What did you do again?"

"Emm... I didn't hand in my homework on Friday, and I was sleeping in class. I was caught by Lao Chen when I played with my phone. I handed it in the morning next Monday."

"Damn it! You are so brave! I don't even dare to take out my phone in class now! I don't understand it and listen with a bit of the bullet!"

"Stop talking nonsense. If you want me to help, please write a review for me!"

"No, Old Chen knows my handwriting! He will definitely tell at a glance that I wrote it, and you will be more troublesome at that time!" Wang Xu thought for a while: "But I can teach you how to write it! I have always had experience. First of all, you must admit your mistakes first, and your attitude must be sincere, ahem..."

Seeing Liu Yuchen looking over with a strange look, Wang Xu coughed: "Anyway, as long as you help, I will teach you how to write, how about it?"

"Yes!" Li Yiyang quickly agreed: "You can tell me what you want to ask! I will definitely tell you what I know!"

When Wang Xu saw that it was OK, he quickly asked Liu Yuchen to call Li Yiyang.

As a result, after chatting for a few words, Li Yiyang was a little confused.

He thought Liu Yuchen was going to talk to him about what car was good, starting speed, performance advantages, etc., but as soon as he opened his mouth, he talked about the motherboard and what parts of the intelligent control unit involved in the car body.

How could I know this the hell!

"Stop! Liu Yuchen, I'm really sorry. I don't know what you asked yet!" Li Yiyang naturally smiled bitterly on the other end of the phone: "I really can't help with this!"

Liu Yuchen was suddenly disappointed and handed the phone to Wang Xu helplessly. Wang Xu frowned, and quickly answered the phone and said, "Li Yiyang, do you still want me to teach you how to write a review? Why can't you help with this little bit!"

"Damn! Who would know these things normally?"

Li Yiyang paused: "Hey! I can't help you later! Look at my brain, I almost didn't react. I have hired a lot of repair masters in my 4S shops. Isn't it all over to ask them??"

This conclusion happened to be a walk on the spot.

About ten minutes later, Li Yiyang and Wang Xu and Liu Yuchen met at a 4S shop in Da Bengal.

As soon as they entered, the employees of the 4S store saw that Mr. Li came, and they dared not be negligent. The manager quickly walked up and smiled and said, "Master, what wind has blown you today!"

Li Yiyang was too lazy to talk nonsense, so he asked the manager to take him to find the repair master of the 4S store. The manager quickly led the way and soon walked to the repair shop behind the 4S store and invited the 4S store's master to come over.

"Young Master, this is the most powerful master in our store. I have been in this business for almost 20 years. He can basically guess what the car has wrong with it at a glance!"

"Oh, okay, please trouble you."

Good guy!

I'm sorry to you, I'm so frightened that I'm so scared to the manager.

When did Li Yiyang speak so politely!

The manager left uneasy, so Li Yiyang quickly asked the master to sit down and asked for some questions.

The master naturally dared not neglect.

Then Liu Yuchen spoke, and the question he asked was naturally similar to the previous one.

Intelligent control unit, electronic control unit... etc.

The master was also confused.

Is the question so professional?

"Wait, wait, little girl, it's hard for me to explain these questions to you in a short while. Otherwise, a car has been removed and repaired. I'll take you to take a look and explain it to you!"

"OK, thanks!"

The master quickly brought everyone to the car and started explaining.

"First of all, this electronic control unit, here is the main control...and then divided from this line are five subcontrols..."

Liu Yuchen naturally listened seriously and kept nodding.

Li Yiyang and Wang Xu looked at each other.

"Does Liu Yuchen understand?" Li Yiyang couldn't help but mutter: "I listened for a long time but couldn't understand what they were saying!"

"Just kidding!" Wang Xu immediately raised his head: "That must be understandable!"

"If you can understand, you can understand it! Why are you following you??"

"Ha..." Wang Xu didn't explain, just showing off.

That is our future wife!

genius!

How could a mortal like you understand?

The master talked for half an hour, and Liu Yuchen almost understood it, and then said quickly: "Well, is there any ready-made motherboard? I want to take a look?"

The master was stunned: "Uh!? Can you understand, little girl? It's still quite complicated."

Liu Yuchen smiled and said, "You can understand it."

The master actually didn't take it seriously, just thought it was because the children were curious and came over to take a look. So he took Liu Yuchen to the goods warehouse and took out some motherboards, but they were all similar. After all, they were all models of the same brand.

When Liu Yuchen took it and saw it, he suddenly realized: "Oh, so that's how it is set up. Is the main control unit and the electronic control unit integrated through parallel lines? It feels really interesting."

“…”

Master:?

Do you also know how to distinguish between lines?

Do you also know about integration!?

The master's head is buzzing!

Even they thought about this high-tech product for a long time, and only after practicing it was possible to understand the situation of the motherboard...

This little girl knows what's going on at a glance!?

"Master, the chip of the smart control unit above uses RI-7, are there any other chips?"

Master: “…”

Do you also know what model of the chip is!?

"This chip is commonly used because it is not too expensive and has a complete range of functions. After all, there are not many places that require intelligent operation, and the computing power is just enough..."

"Well, it's actually almost the same." Liu Yuchen nodded slightly and muttered thoughtfully: "If you change to the ri-12 chip and add twenty-two functional units, the computing power should be enough, and maybe you can still add some of the computing power..."

Master: “…”
Chapter completed!
