Tao Guangming suddenly remembered Ji Qingtao's words: "The biggest sin in my life is knowing Li Wenjun."
That's right, if it weren't for Li Wenjun, how could I have such a mess of seniority? ! !
He blushed, turned and left without saying a word.
Li Wenjun called him from behind: "Hey, why are you leaving? Didn't you just come here?"
Tao Guangming said: "I'm upset. I'm going to live in the mountains for a few days. No one should bother me."
Tang Zhaonian said: "Hey, I'm talking about niece and son-in-law, even if you really become a monk, this relationship is still here and cannot be avoided."
Tao Guangming turned around and shouted hysterically: "You are so annoying!!"
Li Wenjun went back to discuss with Gu Zhanyan in the evening: "How about we have another child. Now that Li Jinyan is older, it is no longer fun."
Gu Zhanyan sighed: "Please spare me."
Li Wenjun remembered the scene when Gu Zhanyan had a difficult childbirth and the room was full of blood, and shuddered: "Forget it. Just pretend I didn't say anything."
-----
Dong Qingjun and his colleagues completed the assembly and production of the redesigned electric vehicle prototype. They used the "artificial retarded" driverless system to test the vehicle at the test track for a month, and tried it several times on the road before they dared to switch to manual driving and allow people to ride on it.
The three people borrowed asbestos fireproof suits and put them on, and also removed the door.
That way, if something happens, they can jump right out.
Li Wenjun attaches great importance to the research and development of electric vehicles. In the past, whenever he was in the "Wenjun New Town", he would come to see the test vehicles and make suggestions, and today was no exception.
Seeing that Dong Qingjun was fully armed, he was a little dumbfounded and said: "Since you are so scared, just one person can go up. Why do all three of you have to go up?"
Dong Qingjun said: "Yes, you two go down."
Huang Liping held the fire extinguisher, shook his head and said, "We developed this together, how can we let you take risks alone?"
Du Xinwei: "Yes, it would be good to have one more person to give advice."
Li Wenjun: "Okay, drive slower."
Dong Qingjun ran ten laps at a speed of 40 kilometers per hour, reversed the car uphill and downhill, turned around, started on a hill, made a one-sided bridge, and made a quick 180-degree turn. No major problems were found.
After he parked the car, Huang Liping and Du Xinwei immediately got out of the car and vomited into a mess.
Dong Qingjun's face turned pale and he kept retching.
After finally regaining his composure, Dong Qingjun said intermittently: "The acceleration is fast, the driving is very stable, and there is almost no noise. It is the same as what we have detected with instruments before. I just don't know why I am so motion sick."
Motion sickness cannot be detected by a machine at all. You have to sit on it to find out.
Li Wenjun laughed: "Motion sickness is also called motion sickness. The human body's balance system is completed by the cooperation of the three major sensory systems of vision, proprioception and vestibule. When the sensory information of any system conflicts with the other two systems, a feeling of dizziness will occur. It means that your senses and brain respectively judge that the state of motion is inconsistent, resulting in confusion. There is no white noise in an electric car to distract attention, telling the brain that the car is in motion, and then accelerates so fast that people cannot predict it, so they become dizzy. It’s even worse. Bumpy roads, many curves and constant braking can also cause motion sickness.”
Dong Qingjun said: "How to solve it?"
Li Wenjun: "As for the problem of too fast acceleration, you need to study the torque output curve and try to make it as smooth as possible. It cannot be as abrupt as it is now, where it takes off directly as soon as it is started. And you must carefully study the user's 'acceleration pedal depth-driving acceleration' curve. This means that customers have a psychological expectation based on their daily experience of driving a gasoline truck on how deep they step on the pedal and how much acceleration they will get. Your design must meet the customer's psychological expectations. If the road is uneven or there are too many speed bumps, air suspension can be used to cause bumps. Systematic solutions are also needed for fuel vehicles. You can discuss this with Factory Director Han."
Dong Qingjun: "Air suspension, what is it..."
Li Wenjun said: "Beautiful country was the first to use it in cars fifty years ago. You can check the information for the specific principle. A simple description is to change the traditional method of fixing the car chassis on the axle to an adjustable-height chassis on springs. .The trip computer will judge the change in the distance between the chassis and the ground based on the signals from sensors located near the front and rear wheels, and control the air compressor and exhaust valve to automatically compress or extend the spring, thereby lowering or raising the vehicle. The gap between the chassis and the ground is used to increase vehicle stability at high speeds or passability in complex road conditions.”
Dong Qingjun became excited: "It's like sitting on a spring bed."
Li Wenjun: "That's a bit like that. But the spring of the spring bed is passive expansion and contraction, while this one is active expansion and contraction to adapt to changes in conditions."
"Interesting, interesting, we will do this next." Dong Qingjun said to Du Xinwei and Huang Liping, "You drive back, I will go to the library to check information."
Then, regardless of whether Li Wenjun was still here, he jumped on his bicycle parked at the door and ran away.
Li Wenjun couldn't laugh or cry, shook his head and smiled bitterly.
Tian Runan called to tell him that they had made the first version of a website and asked Li Wenjun if he had time to take a look.
Li Wenjun was a little surprised: "Is it going to be fine so soon?"
In fact, their servers are not that powerful yet and may not be able to withstand too many customers visiting the website at the same time.
There are also settlements with banks, warranty, refunds...
There are still many problems to be solved.
Tian Runan: "It's just a very rough first version. You know, it's not that easy to get a program that is simple, smooth, practical, and free of big bugs."
Li Wenjun: "This aspect of knowledge is my blind spot. I can only experience it and tell you whether it works well or not, and where it doesn't work. It's up to you to improve it specifically. But I can help you find help."
In order for Tian Runan to concentrate on this, the autonomous driving program did not dare to disturb him.
Tian Runan: "Then I will send the URL to Mr. Li, and we will talk about it after Mr. Li tries it out."
Li Wenjun called Tao Guangming to the office, then opened the URL sent by Tian Runan, and said: "This will be our online shopping portal from now on. Suppose you are now a customer and want to purchase a 'Wenjun Industrial' bicycle at home. You Give it a try.”
Tao Guangming sat down and muttered: "What is online shopping?"
Li Wenjun said: "Just place an order online and we will deliver it to your home."
Tao Guangming frowned: "It's for free."
Li Wenjun sighed: "Can you try it first? I can't explain it to you right now."
Tao Guangming: "No, you must explain it to me clearly. This is a big deal."
Li Wenjun: "Suppose you want to buy something in Hong Kong City, but you can't go there, what should you do?"
Tao Guangming: "If you don't want to buy it, buy it somewhere else."
