Chapter 228 Double Verification and Double Insurance

Zhang Feiyang also entered the state at this moment.

"Boss, let me introduce the 'remote intervention' function to you first."

"As I said just now, other car companies now have special staff on 'unmanned buses' for various reasons, the most important of which is safety issues."

"After all, the bus is a means of public transportation, and safety issues are very, very important. There are staff on the bus, and even if there is a problem, it can be dealt with in time."

"For example, in the unmanned bus with 'steering wheel mode', the staff can immediately take over the vehicle manually after encountering an emergency; Press the 'emergency button' to forcibly stop the vehicle."

"but……"

"However, if we want to truly realize the 'unmanned bus' without any staff on board, we must consider various safety issues and emergency handling without the presence of staff."

"Simply assume a scenario. If our 'unmanned bus' deviates from the route due to procedural problems, does not stop at stops, or even suddenly increases the speed limit from 40 to 60 or 70 yards, then there will be no staff in the bus. Once encountered How should we deal with such a failure event?"

Hu Lai frowned slightly, and this scene immediately appeared in his mind.

An "unmanned bus" without a steering wheel, brakes, or accelerator is rampaging in the urban area. All the passengers in the bus have no way to stop him. This scene is really like the horror scene in the science fiction movies I saw when I was a child. .

"So, we came up with a solution, which is to use the 'remote intervention' function to replace the staff and monitor the operation of the unmanned bus through the 'remote intervention' function!"

"Under normal circumstances, the 'unmanned bus' will maintain normal communication with the command center. Once the 'unmanned bus' detects vehicle error information or an abnormal alarm occurs in the vehicle, our background command center will be reminded immediately, and then processed through the background .”

Speaking, Zhang Feiyang pointed to a red button next to the door of the "unmanned bus" and said:

"This is the emergency button we set up. As long as a passenger presses the physical button of the emergency button, the vehicle will automatically slow down. At the same time, our command center will immediately receive the alarm, and at the same time check the situation in the car in real time through the camera in the car."

"If it is a vehicle problem, we will immediately intervene remotely and control the vehicle; if it is a security incident, we will immediately contact Party J."

Hu looked at the red emergency button inside the car, then at the camera above the car, and nodded.

indeed.

If the vehicle is out of control, this can also be regarded as an emergency method, a means of safety protection.

Moreover, this "emergency button" is not only for vehicle problems, but if you take an "unmanned bus" at night, you can call for help in time if you encounter danger or harassment.

but.

Hu Lai also has doubts in his heart. The "emergency button" can only be regarded as a passive safety warning, which needs to be activated by passengers. If it is really too late to respond in an extreme situation, or if no one notices the abnormality of the bus, then...

Just when he was wondering, Zhang Feiyang continued:
"In addition to the panic button, our 'remote intervention' feature also provides proactive warning."

"Before each bus line is put into use, we will actually carry out 'bus line data' on this bus line, and then record all the station information, time, speed and other related information of the entire line into our cloud server. "

"All of our 'unmanned buses' will adopt the unmanned operation mode with double verification and double insurance."

Hearing Zhang Feiyang's important points, Hu Lai was also a little curious.

"Active warning?"

"Digitalization of bus lines?"

"Double verification, double insurance?"

Zhang Feiyang hummed and explained:
"When the 'unmanned bus' is driving normally, it still uses the high-definition high-frame camera and millimeter-wave radar of the bus itself, as well as the on-board AI smart chip to realize unmanned automatic driving."

"but."

"During the operation of the entire line, we are the first to upload hundreds of calculated data to the cloud server for matching with the 'bus line data' that we have entered into the cloud server before. If the matching similarity is above 97%, So it proves that the 'bus' at this time is running according to normal procedures, and everything is normal."

"And once the matching degree of the data does not reach 95%, then there must be a problem in a certain link."

"For example, the normal speed from Station A to Station B should be 30KM/H. If the actual speed reaches 40KM/H, then our command center will receive an alarm immediately; of course, if the speed is lower than 30KM/H, we will check Whether it is a bus failure or whether there is a traffic jam, etc."

"We now have second-to-second communication, which means we can actually get an alert the next second that the bus deviates from the intended route, which is even faster than if there are staff on the bus."

Speaking of this, Zhang Feiyang also looked proud, and finally said:
"And, in our plan, if we already need to force stop the vehicle through the command center, then there must be a very serious failure."

"So, in order to deal with such a situation, we specially added a separate set of simple emergency braking device on the 'unmanned bus', which only obeys the control of the command center and does not accept the control of the on-board chip."

"In this way, even if the logic of the original computer chip is completely wrong, even if the entire machine fails, the emergency braking device as a backup can also play a role in the first time, forcing the bus to stop and open the door!"

"This is the active warning, double verification, and double insurance in our 'remote intervention'!"

Hu Lai's blood boiled when he heard it. He didn't expect the project team to make such a detailed security function and use the existing technological level to make the plan without any flaws.

Even just listening to Zhang Feiyang's introduction, you can feel that the project team has put in a lot of thought and effort.

He turned his head and was about to praise the project team, but the designer from BYD behind him suddenly couldn't help but speak.

"so amazing."

"Mr. Hu, I have to say that your design concepts and ideas are far beyond ours."

"I am also participating in BYD's 'unmanned bus' project, but our current debate is still on whether to retain the steering wheel design. For safety reasons, we have not even thought of a plan that does not require staff."

"And what about you? Now you have all started to propose the 'digitalization of bus routes', and also proposed the idea of ​​active warning, double verification, and double insurance to provide security."

"Especially the design of double insurance independent emergency braking device, I have only heard of it in aircraft design."

After finishing speaking, he gave a thumbs up, and he didn't know whether it was a compliment or from the heart:
"Not to mention anything else, just such a design is enough to see that our Phoenix Motors is really ahead of us in the field of 'unmanned public transportation'."

Hu Lai was in a great mood. To be honest, the "redundant design" of the project team really showed the emphasis on bus safety, and he was quite satisfied.

If the probability of a problem with a single system is one in [-], the probability of a problem with both braking systems at the same time is one in a million.

Hearing the praise from BYD's designer and Hu Lai's approval, Zhang Feiyang also showed a smile on his face, and he continued:

"Of course, if we encounter mechanical failures, sudden collisions and other things that cannot be solved online, we can send staff to the scene to deal with them."

"In this way, with the 'remote intervention' function, safety issues can be resolved, and the command center of the bus company only needs one staff member to monitor the normal operation of dozens or even hundreds of 'unmanned buses'."

"Our 'unmanned bus' can be regarded as meeting the city's 'night unmanned bus' requirements, and there is no need to arrange drivers for night buses, which can greatly reduce operating costs and open up more' Night bus lines'."

Hu Lai agreed with Zhang Feiyang's statement very much, but after a while, doubts suddenly arose in Hu Lai's heart, and he returned the topic to the original question.

Hu Lai frowned and asked:

"Feiyang, after you introduced this 'remote intervention' function, I think it is completely feasible to use this solution."

"However, since you all already have the 'remote intervention' solution and have been able to solve the security problem, why didn't you decide whether to use the 'steering wheel mode' before? Isn't this contradictory?"

Zhang Feiyang froze for a moment, then smiled wryly.

"Boss, if you talk about this, you have to talk about the 5G network."

Ok?
Why did you suddenly talk about 5G networks?
Hu Lai listened suspiciously.

"Actually, our 'remote intervention' is a secondary development based on the command center platform of Phoenix Shared Cars."

"As you know, the main job of our car-sharing command center is to analyze the vehicle data at each pick-up point, and then coordinate and dispatch the shared cars in the urban area, using big data to improve customer experience."

"Except for vehicle dispatching, for shared cars in normal use, because they are operated independently by customers, each shared car does not need to maintain communication with the command center at all times, as long as the GPS signal is normal."

"But the 'unmanned public transport' is completely different, just like the 'automatic warning' introduced just now, in order to realize the 'automatic warning' function, it is necessary to realize a communication every second, up to two seconds, which requires very high requirements on the network .”

"Now we have achieved 5G network coverage in key urban areas of Shancheng City, but what about other second-tier and third-tier cities? What about our surrounding cities and counties?"

"not at all."

Speaking of this, Hu Lai already understood why the project team has not decided to adopt the "no steering wheel mode" for a long time.

In mountainous cities, Beijing, Shanghai, Guangzhou and Shenzhen, where 5G is fully covered, the "no steering wheel mode" + "remote intervention" can indeed guarantee the daily operation of unmanned buses.

but.

In third- and fourth-tier cities with insufficient 5G network coverage, without the "remote intervention" function supported by 5G networks, it is simply impossible to achieve high-traffic and low-latency transmission of network communications per second.

And if there is no "remote intervention" function as a safety guarantee, then using the "no steering wheel mode" will have a huge safety hazard.

To put it bluntly, a bus with a steering wheel can be used as a normal bus with a driver when unmanned driving is not working, and a bus without a steering wheel means that it cannot be operated physically , Once something goes wrong, it will be a pile of scrap iron.

Is this to take into account the markets of third- and fourth-tier cities? !

Hu Lai shook his head. He understood that the project team wanted to take care of the market in third- and fourth-tier cities. However, given the current economic situation and 5G planning, it is impossible for third- and fourth-tier cities to achieve 5G network coverage in a short period of time. To enter the third- and fourth-tier cities, it is necessary to redesign the plan, which will undoubtedly increase a lot of costs.

Hu Lai was also very helpless, but he didn't show it on his face. Instead, he put down the topic and asked:

"Feiyang, you said that 'vehicle-road coordination' and 'remote intervention' have been realized. Now that 'remote intervention' is introduced, what about 'vehicle-road coordination'?"

"Vehicle-road coordination?"

Hu Lai's question made Zhang Feiyang's expression stiffen, and then he smiled wryly again.

"Boss, this vehicle-road collaboration actually needs a 5G network even more."

"Do you need a 5G network more?"

Zhang Feiyang nodded affirmatively, then turned his head to look at the project team members accompanying him behind him, and his eyes fell on a young man.

"Boss, Bai Qiang, the team leader of our 'unmanned bus' project team, will tell you about vehicle-road coordination."

As soon as the words fell, the young man named Bai Qiang walked out of the crowd.

When we met just now, Zhang Feiyang introduced Bai Qiang, the leader of the project team. Looking at the young Bai Qiang in front of him, Hu Lai also felt fresh.

Bai Qiang was a little nervous, but soon got into the mood.

He looked at Hu Lai and began to introduce:
"Mr. Hu, in fact, the vehicle-road coordination technology is not complicated."

"It's a technology in itself that's being used to assist driverless self-driving technology."

Assisted driverless self-driving technology?
After saying a word, Hu Lai immediately became serious.

"Mr. Hu, you should still remember the FH0008 incident of our Phoenix car sharing last year, right?!"

Hu Lai was curious. Of course, he remembered the FH0008 incident. At that time, this incident had a great impact. In the end, the pregnant woman named Wang Mei was successfully rescued because of the unmanned automatic driving technology.

Seeing Hu Lai nodded, Bai Qiang showed a smile on his face, and his whole demeanor relaxed a bit.

"At that time, I hadn't joined our Phoenix Motors. Later, when I watched the online video playback, I realized that there were three shared cars separated by a distance of one kilometer, forming a mobile local area network covering 2 kilometers."

"This method of obtaining road conditions through the vehicle in front and behind, and then sharing the data through the cloud server is actually a simple version of vehicle-road coordination."

"Our real vehicle-road collaboration is actually to informatize roads, vehicles, and finally form a three-terminal interconnection with people."

"To put it simply, the essence is to realize the interconnection between cars and cars, cars and roads, and cars and people."

This is the Internet of Everything under 5G?
