"The wire-controlled steering system completely eliminates the mechanical connection between the steering wheel and the steering wheel, completely breaking away from the various limitations of traditional steering systems. It can not only freely design the force transmission characteristics of the car's steering, but also design the angle transmission characteristics of the car's steering, bringing revolutionary changes to the design of the steering characteristics of the car. ⊙," Liu Chen talked casually, ha, this topic is a research topic for his undergraduate degree in his previous life, so he is naturally clear.

Zhuo Ling smiled and said, "It sounds quite interesting."

Ma Rui said with a cold face: "It's so difficult to say, what are the advantages of electric power steering? It seems to be unpractical."

"The traditional steering system is mechanically connected, and the power assist system only saves you some effort, so the steering angle of the front wheel cannot reach 180 degrees. The electronic wire-controlled steering completely eliminates the mechanical rod in the middle. The wheels can be 180 degrees, and the car can be 360 ​​degrees. This way, you can completely learn from the crabs to run sideways. If you encounter a narrow place in the alley, you can walk sideways and move sideways without any obstacles."

Zhuoling clapped his hands and said, "It sounds very good, especially the parking is very convenient, it's really interesting, but this seems to be in the concept stage. I have never seen it on the market. If you build such a car, it will definitely be cool."

"That's true. The concept proposed in 2001 is still in the quest stage. The concept cars have not yet come out. In the future, we can build one to play with it." Liu Chen said seriously at her.

With the burning eyes unintentionally, a red cloud floated across Zhuo Ling's fair face.

"Building a concept car is not easy, so don't bother."

Ma Rui was so angry that he was so unlucky that he deliberately raised a topic to give this kid a warning. Why did he understand this again? Seeing the interaction between the two in the back row, he really wanted to brake and let Liu Chen get out of the car and get out of the car immediately. He held back his anger with such a low air conditioner. His face turned red.

"There are many major auto manufacturers that have not adopted it, and there are probably big drawbacks. The electric power steering is more practical. Ling Ling. It is better for us to study this topic. If Liu Chen has the spare time to learn, you are welcome to join and do some logistics and service work for us." Ma Rui said.

"Senior Ma Rui was wrong. SBW is not because of any disadvantages. Instead, it has many advantages. It not only improves the operating stability of the car, but also makes it easier to integrate with other systems. It is just too advanced and the technical difficulties are too high. The biggest problem is road surface perception."

"Pavement perception? What is this?" Zhuo Ling asked.

"SBW gets rid of mechanical connections and cannot sense the road conditions. This is like an astronaut who loses gravity perception when walking in space. It is very dangerous to have no sense of road when driving at high speed."

"Then it's still not practical in the end!" Ma Rui finally got the chance. Liu Chen's long technical description made him collapse. This is so much more understanding than a graduate student.

"Technical problems will always be solved. Haha, super cool pure electric vehicles may be released in a few years." Liu Chen said with a smile.

Zhuo Ling nodded and said, "Ma Rui, I still think that the sbw mentioned by Liu Chen is a cutting-edge research topic. It is better for us to change it to this topic. Since the electric power has been used in large quantities, there is really not much need for research."

"Yeah." Ma Rui nodded helplessly and finally arrived at the climbing training center. He looked at Liu Chen's face and really wanted to rush up and punch him. Who told you to know so much is simply a monster.

"Senior Ma Rui." Liu Chen shouted.

"What's the matter?" He tried his best to keep a calm tone.

Liu Chen smiled and said, "The valvetroni engine does not require valves. Instead, it eliminates the throttle valve. There is a fundamental difference. Without valves, the engine will be done. If the throttle valve is removed, the engine will be directly controlled by electronically controlling the opening depth of the intake valve to control the intake volume. The opening depth of the intake valve is the shallowest 0.25mm, the maximum is 9.7mm, a difference of 38.8 times. The reaction time required to change from the shallowest to the deepest is only 0.3 seconds."

"I understand, thank you for the reminder!" Ma Rui took a deep breath and walked first.

Zhuoling smiled and said, "Senior brother, you know so much."

"Senior sister was joking, but I just happened to have studied automotive electronics. I know nothing about other aspects, such as the movie that my senior sister is going to explain today."

"Don't you really understand? The movie I'm analyzing today is "Walking in the Clouds", which is a story about pure love and warm family."

"Ha, I can't wait to listen to my senior sister's explanation."

"Are you going to listen again? I feel nervous when I give a lecture in front of you. If there is any omission, don't point it out in person. Let me secretly tell me after class." Zhuo Ling smiled playfully, very cute.

When the two walked into the training center, Xiao Yue looked around on the side. When she saw Liu Chen, she shouted and winked. Liu Chen followed him to the hidden place next to the stairs and said angrily: "What are you doing sneaky? Do we have any secrets that we can tell?"

"Brother, you have been very close to Zhuoling recently. Can you help me?"

Liu Chen looked at him and thought to himself, "Brother, how old are you, you can't think of the little girl, "Brother Xiao, how old are you this year?"

Xiao Yue looked at herself and said, "Twenty-three, I haven't been graduating for a while."

"You...you are...twenty-three?"

He is big and thick, and his skin on his face is not very good, he has many acne marks and a thick beard. It looks like he is thirty-five upwards. Liu Chen really didn't expect it to be so small.

Sorry, she touched her face, Xiao Yue said, "Hehe, I'm a little anxious. I haven't shaved my beard when I was in high school. When I was in the first year of high school, a senior in the second year of high school called me uncle. It was so funny."

Is this really funny? Liu Chen smiled and immediately said with a stern face: "Hey, I won't give you love letters or something. Actually, I think you'd better not try it, and you'll be hit in vain."

Xiao Yue was stunned, "Brother, what are you talking about?"

"What are you trying to ask me for help?"

"I saw that the courseware you made was vivid, so I wanted you to help me install matlab. Haha, it would be best if I could give it a guide. If Principal Xue asks me to do anything in the future, I don't have to do carpenter work."

"That's all?"

"Just this matter, otherwise what else can there be?" Xiao Yue opened her innocent big eyes.

Liu Chen was so upset, "Brother, you are taught by the physical education teacher. There is no logical relationship between you before and after a sentence. Let me say something like Zhuoling first, but I'll help you, and I'll be tempted."

"Okay, this is absolutely fine. You come to my house to find me tonight."

"Okay, hehe, then I won't disturb you from listening to Teacher Zhuo's lecture." Xiao Yue had just walked a few words and suddenly stopped again, turned around and asked, "Are you Liu Chen?"
