"Do you want to prepare?" Kong Guanyu asked, "Prepare some materials or something." ”

"Forget it!" Ji Fan said, "It's not to welcome any investors and big customers, that's it." ”

They continued to work, and after more than an hour, Lu Zixin and others arrived.

"Right here, the last time I was here, although the place is smaller, but it's really good. Xu Xiuying gave Lu Zixin the way.

"Welcome to visit our company. Out of politeness, Ji Fan came over to greet him in person.

Lu Zixin said: "Today I want to learn more about your project. Next to me is Mr. Zhu Liangyan, who is also an expert in the field of unmanned driving. ”

Zhu Liangyan is in his forties, wearing a neat suit, because he is much older than Lu Zixin, so Ji Fan pays more attention to him, and guesses in his heart that this Zhu Liangyan may be a capable person.

"Hello sir, please come in. ”

They walk into the company and look around. The rest of the Forerunner Startup seems to be familiar with this kind of scene, and they are busy with their own work.

"Did you make this radar yourself?" Zhu Liangyan asked curiously when he saw the on-board radar.

"It's what we improved. Zhang Wei introduced, "It was originally a product of a German civilian radar company, but after we bought it, we improved it for unmanned driving." ”

"With this radar, the car can detect obstacles and moving objects within 100 meters of the surrounding area in advance, and then adjust the driving mode through the intelligent system. ”

Lu Zixin questioned and said: "What if there is wireless interference and other interference with radar?

"This ...... In general, there will not be so much interference on the road, and our radar will prevent some interference. Zhang Wei explained.

"The road situation is very complex and there is no room for surprise. Zhu Liangyan said, "How do you solve the difficulty of accurate positioning of vehicles?"

Hearing Zhu Liangyan's question, Ji Fan and the 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 feed back to the system to ensure that autonomous driving does not go wrong.

At present, even the most advanced positioning systems on the market have an error of five to ten meters, which is a very serious error for a fully autonomous vehicle!

"In general, we use Huaxia's Beidou satellite positioning system. The on-board computer automatically corrects every 10 seconds, and we use odometer and gyroscope inertial navigation when the positioning system is affected by bad weather, passing through tunnels, etc. ”

After Ji Fan finished speaking, Zhu Liangyan directly pointed out the problem in his words and said: "There will be a cumulative error in the inertial navigation unit, and if the tunnel is too long, the cumulative error will increase. And this increases the cost of fully autonomous driving systems. ”

"There's no way around it, our solution is already the best in the world. These technologies are constrained by sensor devices and can only be solved unless sensing systems and positioning services are more complete. Ji Fan was very calm.

Zhu Liangyan nodded, Hongxin Group had also encountered this problem when it was studying this project before.

They continued to look and asked a lot of questions.

To Lu Zixin's surprise, this pioneer startup was a little better than he imagined. Although the company is small and the registered capital is small, when it comes to technology, they are really not bad and can already achieve a high degree of automation.

In the field of autonomous driving, there are four phases: driver assistance systems, partially automated systems, highly automated systems, and fully automated systems.

At present, no company in the world dares to claim to have reached Stage 4, and the leaders are basically Stage 3.

The origin of Ji Fan and others is not simple, many people in their company started their own businesses together after leaving other technology companies, including executives and technical talents.

"Can you show us the actual road test?" asked Zhu Liangyan, who had been with the company for a day.

Ji Fan and the others didn't do anything, so they accompanied them to visit and explain.

Now hearing that they still have to look at the situation on the road, several people feel a little tired.

"Yes, we test on designated roads. Ji Fan still agreed, he still had a glimmer of hope in his heart, this Zhu Liangyan is said to be an executive of a large company, if only their company could fancy this project and invest hundreds of millions in the pioneer startup.

As for Lu Zixin next to him, he regarded him as Zhu Liangyan's assistant and didn't pay much attention to it.

Their company's special test vehicle is on the road, driving slowly in an area with fewer pedestrians and vehicles.

In front of the real-time monitoring 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 react accordingly when encountering pedestrians or vehicles.

"Is it too slow?" Lu Zixin asked.

"It's a bit slow, but our sensing system is not perfect enough, and if it's fast, we're afraid of safety accidents. Ji Fan explained.

"Oh. ”

Lu Zixin also watched the actual test, but it was not as amazing as he imagined. The reason is probably that the speed of the car is slow, and the intelligent processing and response speed are not agile enough.

"Mr. Zhu, what do you think? We are trying to contact Hongxin Intelligent Development Co., Ltd. and want to cooperate with them to solve the most difficult artificial intelligence problem in the unmanned driving problem. As long as there is a certain amount of capital investment, within a year, we may break through to the fourth stage of unmanned driving, fully autonomous driving!"

Ji Fan and others were promoting the company's entrepreneurial project to Zhu Liangyan, Zhu Liangyan just smiled and said: "You are doing a good job, although there is still a gap in the technology of companies such as Qiandu and Google, but in the field of unmanned driving, it is also a first-class start-up company." ”

"For the rest, we'll have a chance to talk about it. ”

Hearing his words, Ji Fan and the others were a little disappointed, this means that they don't look down on their projects?

Xu Xiuying looked at Lu Zixin and saw that he was thinking, so she didn't interrupt him.

Lu Zixin was thinking about whether to buy this company or Hongxin to restart the unmanned project, and he needed to go back and talk to Zhu Liangyan.

"Let's do this today, thank you for your reception, and I'll be in touch tomorrow. Lu Zixin said.

When Xu Xiuying heard this, her beautiful eyes lit up, this is still a play! She hurriedly hinted at Ji Fan and said, "Don't send it yet?"

Ji Fan sighed helplessly in his heart, but still kept polite and sent Lu Zixin and Zhu Liangyan downstairs.

But as soon as he returned upstairs, he was dissatisfied with Xu Xiuying: "Xiuying, you brought the two of you to play with us today, right? It's been a whole day, and our entire company hasn't done anything, so we introduced the project to the two of them, and we were sent away with a word, is there such a play?"

Xu Xiuying not only did not admit her mistake, but also retorted: "Play? Ji Fan, do you think I brought someone to play with you! Do you know who they are?"

"Who?"

"I can't tell you now, but I'm sure if they find you again. Your company will be developed!" Xu Xiuying said confidently.
