"Do you want to prepare some things?" Kong Guanyu asked, "Prepare some materials or something."
"Forget it!" Ji Fan said, "It's not like we're welcoming investors or big customers, so that's fine."
They continued to work, and after more than an hour, Lu Zixin and others arrived.
"It's right here. I was here last time. Although the place is small, the work is really good." Xu Xiuying led the way to Lu Zixin.
"Welcome to visit our company." Ji Fan came to greet him in person out of politeness.
Lu Zixin said: "Today I want to learn more about your project. The person next to me is Mr. Zhu Liangyan, who is also an expert in the field of autonomous driving."
Zhu Liangyan was in his forties and wore a neat suit. Because he was much older than Lu Zixin, Ji Fan paid more attention to him, guessing that Zhu Liangyan might be a capable person.
"Hello sir, please come in."
They walked into the company and looked around. Other employees of the Forerunner startup company seemed to be used to this kind of scene, and they were all busy with their own work.
"Did you make this radar yourself?" Zhu Liangyan asked curiously when he saw the on-board radar.
"We improved it," Zhang Wei introduced. "It was originally a product of a German civilian radar company. After we bought it, we made improvements for unmanned driving."
"With this radar installed, the car can detect obstacles and moving objects within a hundred meters around it in advance, and then adjust the driving mode through the intelligent system."
Lu Zixin raised a question and said: "What if there is wireless interference and other interference if the radar is installed? Then isn't the self-driving car 'blind'?"
"Well... Generally speaking, there won't be that much interference on the road, and our radar can also prevent certain interference." Zhang Wei explained.
"The road conditions are very complex and there is no room for any surprises." Zhu Liangyan said, "How did you solve the problem of precise vehicle positioning?"
After hearing Zhu Liangyan's question, Ji Fan and others felt that he was a real expert. Today's motor vehicles have positioning systems, but for fully autonomous driving, they need more accurate positioning data to be fed back to the system to ensure that autonomous driving does not make mistakes.
Currently, even the most advanced positioning systems on the market have an error of five to ten meters. This is a very serious error for fully autonomous vehicles!
"Under normal circumstances, we use China's Beidou satellite positioning system. The on-board computer automatically corrects every ten seconds. When bad weather or passing through tunnels affect the positioning system, we use odometer and gyroscope inertial navigation."
After Ji Fan finished speaking, Zhu Liangyan directly pointed out the problem in his words and said: "The inertial navigation unit will have a cumulative error. If the tunnel is too long, the cumulative error will increase. And this will increase the cost of the fully autonomous driving system. ”
"There's nothing we can do about it. Our solutions are already world-leading. These technologies are restricted by sensor equipment and can't be solved unless the sensing system and positioning services are more perfect." Ji Fan is very calm.
Zhu Liangyan nodded. Hongxin Group had also encountered this problem when studying this project before.
They continued to look and asked many questions.
What surprised Lu Zixin was that this pioneer startup was even better than he imagined. Although the company is small and has low registered capital, when it comes to technology, they are really good and have been able to implement a highly automated system.
The field of driverless driving is divided into four stages: driving assistance system, partially automated system, highly automated system and fully automated system.
At present, no company in the world dares to claim that it can reach the fourth stage, and the leaders are basically in the third stage.
The backgrounds of Ji Fan and others are not simple. Many people in their company started their own businesses after leaving other technology companies, including senior executives and technical talents.
"Can we see the actual road test?" Zhu Liangyan asked, they have been in this company for a day.
Ji Fan and others did nothing, just accompanied them to visit and explain.
Now that they heard that they still wanted to see the situation on the road, several people felt a little tired.
"Okay, we will test it on the designated road." Ji Fan agreed, still holding on to a glimmer of hope in his heart. It is said that Zhu Liangyan is an executive of a large company. If their company can take a fancy to this project, he will give it to his predecessors. Just invest hundreds or tens of millions in Xingzhe Startup Company.
As for Lu Zixin next to him, he regarded him as Zhu Liangyan's assistant and didn't pay much attention to him.
Their company's special test vehicle took to the road, driving slowly in an area with relatively few pedestrians and vehicles.
In front of the real-time surveillance screen, Lu Zixin watched the specially modified driverless commercial vehicle driving on the road.
Under normal circumstances, it naturally has no problems at all, and can respond accordingly when encountering pedestrians or vehicles.
"Is it too slow?" Lu Zixin asked.
"It is a bit slow, but our sensing system is not perfect enough. If it goes too fast, we are afraid of safety accidents." Ji Fan explained.
"oh."
Lu Zixin also watched the actual test, and it was not as amazing as he imagined. The reasons are probably the slow speed of the car and the insufficient response speed of the intelligent processing.
"Mr. Zhu, what do you think? We are trying to contact Hongxin Intelligent Development Co., Ltd. and want to reach a cooperation with them to solve the most difficult artificial intelligence problem among autonomous driving problems. As long as there is a certain amount of capital investment, within a year Within, we may be able to break through to the fourth stage of driverless driving, fully autonomous driving!”
Ji Fan and others were promoting the company's entrepreneurial projects to Zhu Liangyan. Zhu Liangyan just smiled and said, "You are doing pretty well. Although there is still a gap in technology between Qiandu and Google, in the field of autonomous driving, It can be considered a first-class startup company.”
"As for the rest, let's talk about it when we have the chance."
After hearing his words, Ji Fan and others were a little disappointed. Does this mean they don't like their project? Then this whole day has been wasted again!
Xu Xiuying looked at Lu Zixin and saw that he was thinking, so she did not interrupt him.
Lu Zixin was wondering whether he should acquire this company or whether Hongxin should restart the driverless project. He needed to go back and talk to Zhu Liangyan.
"Let's do this for today. Thank you for your reception. I'll contact you tomorrow." Lu Zixin said.
When Xu Xiuying heard this, her beautiful eyes lit up, there was something going on! She hurriedly hinted at Ji Fan and said, "Why don't you send it off?"
Ji Fan sighed helplessly and sent Lu Zixin and Zhu Liangyan downstairs politely.
But as soon as he returned upstairs, he was dissatisfied with Xu Xiuying: "Xiuying, you brought the two of you here to play with us today, right? It's been a whole day, and our entire company has done nothing, just introduce them to them The project ended up dismissing us with just one sentence, is there such a thing?”
Xu Xiuying not only did not admit her mistake, but also retorted: "Playing? Ji Fan, you think I brought people to play with you! Do you know who they are?"
"Who?"
"I can't tell you now, but I'm sure that if they find you to cooperate again, your company will be prosperous!" Xu Xiuying said confidently.
