As soon as the words were finished, the members of the project team accompanying him also spoke quietly.

The project team is composed of personnel from various departments, most of them do not know about vehicle-road collaboration technology. At this time, they heard the team leader Bai Qiang’s introduction, and everyone was not as nervous as before when facing Hu Lai, and the atmosphere became more active.

A young design department member asked:

"Old Li, you are from the technical department. Is the vehicle-road collaboration mentioned by the team leader the Internet of things the Internet of Things?"

“…”

"I am professionally responsible for power systems and don't know much about network communication. However, I heard from the team leader that 'road informatization' is actually installing high-definition cameras on the road at red street light intersections, smart street lights and other equipment, and then real-time

The road image is uploaded to the cloud server via the network.”

"Well, what does vehicle informatization mean?"

"As the name suggests, vehicle informatization is to upload road conditions around the car to a cloud server."

The voices of discussion in the crowd reached Bai Qiang's ears. He smiled and turned to Lao Li and said:

"Old Li is right, but not completely right."

The discussion in the crowd came to an abrupt end as Bai Qiang spoke, and everyone's eyes fell on Bai Qiang.

He smiled and said:

"The 'road informatization' that Lao Li said is correct. The 'road' that car-road collaboration is to install 'eyes' on all traffic roads in the city, use a high-definition camera to obtain real-time road conditions and then transmit them to the cloud server.

.”

"And Lao Li's explanation of 'vehicle informatization' is not accurate. In fact, 'cars' in vehicle-road collaboration will not upload information images of surrounding road conditions to the cloud server. The data uploaded by 'cars' is very

Few."

Um?

Bai Qiang's views surprised many people.

In everyone's impression, isn't the vehicle-road collaboration mean that cars should upload information to cloud servers, and roads also provide information to cloud servers. Will the combined data after the two "two-way" are fed back to the car?

Why is this a little different from what I remember?

Bai Qiang didn't deliberately keep it a secret and explained:

"In fact, you can imagine what it would be like if all cars on the road uploaded the image information around them to the cloud server in our existing network environment, even if there is full coverage of 5G networks.

Scene?”

"The data of dozens of vehicles and thousands of vehicles is acceptable. If hundreds of millions of vehicles across the country transmit data to the cloud in real time, how will such a huge amount of data be processed? How can the network traffic cost be borne?"

"so."

"In practical applications, vehicle-road collaboration 'cars' generally only transmit a small amount of data upwards unless it triggers the preset 'alarm mechanism' in the car, such as feeling the strong collision of the vehicle, such as discovering traffic jams, etc.

.”

"The 'road information sharing' function we use now on 'Qingluan' cars is actually the same principle."

"We 'Qingluan' will only trigger the 'collection mechanism' when we find traffic jams, road repairs or even potholes. Only after the mechanism is triggered will the corresponding data be uploaded, and finally the cloud server will be calculated and shared with all'

Qingluan's car owner."

Speaking of this, everyone basically understands the principle of vehicle-road coordination.

Director Zhang, who had been accompanying Hu and had not spoken, nodded frequently at this time. He had previously hosted the "Qingluan" new product launch conference, so he also knew a little about the "road information sharing" technology.

He asked in a timely manner:

"Captain Bai, can I understand this way?"

"In 'vehicle-road collaboration', the main force is 'road', which takes the information provided by 'road' as the cornerstone. 'vehicle' is just an auxiliary, as a supplement to emergencies and details."

Bai Qiang nodded repeatedly.

"Yes, for the 'vehicle-road collaboration' technology, road access information is the main source, and cars are just supplements."

"Only after 'road informatization', a large number of fixed cameras can truly obtain various information on the road in real time and quickly."

After saying this, Bai Qiang changed his tone before Director Zhang could answer:

"Mr. Zhang, you should know that our Phoenix Automobile's L3-level 'unmanned autonomous driving' technology is very awesome."

"Whether it is on shared cars or on our 'Qingluan', we can achieve a 100% response speed below 50KM/H."

Director Zhang didn't know why Bai Qiang suddenly mentioned this, but he still nodded.

Bai Qiang continued:

"but."

"You should also know that our speed is below 50KM/H, which means that the computer can react 100%, rather than 100% avoid accidents."

"For example, if someone is driving towards the car and someone suddenly comes up with a zebra crossing, our technology can quickly respond to avoid vehicles and pedestrians, but it does not mean that it can avoid accidents 100%!"

"So, I just said that the 'vehicle-road collaboration' technology itself is used to assist 'unmanned autonomous driving technology'. Once the 'vehicle-road collaboration' is realized and the road informatization is realized, then all connected to the 'vehicle-road collaboration' system

All cars can obtain relevant road information in the scenes, and even how many pedestrians are on the zebra crossing will know in advance."

"In this way, the 'unmanned autonomous driving' technology will become safer, and the car's sensing of the scene will become without blind spots; under the 'vehicle-road collaboration' system, the computing chip can even sense the road information in advance, truly realizing it

Perception beyond the visual range!”

Director Zhang breathed in anger.

However, before he could speak, Bai Qiang turned to look at Hu Lai, with a look of expectation on his face.

"So, the core of 'vehicle-road collaboration' is to realize 'road informatization'. Only by achieving full network video coverage of the entire city's road network can 'vehicle-road collaboration' be truly realized."

"Once 'vehicle-road coordination' is achieved, in the future, our cars will not only enter a city in a geographical sense, but will also enter each airspace like a flight.

Tower air traffic control.”

"In the future, when entering each city, each car will first connect to the city's 'vehicle-road collaboration' system, and then you will know all the road conditions in this city!"

After saying this, Bai Qiang smiled slightly and looked at everyone:

"This method should be the operating mode of the future city."

Before he knew it, Bai Qiang talked a little deeper.

But before everyone could react from his words, he broke the silence himself:

"So, this question goes back to the question we just did!"

"The 'vehicle-road collaboration' function we envision requires the transmission of a large amount of data to the cloud server for analysis and processing. There are thousands of cameras in each city. After analysis, such massive data must be returned to all.

The car in the 'vehicle-road collaboration' system."

"Such huge data transmission requires very high network speed and transmission quality, and it is simply impossible to achieve the current 4G network."

"So, this is also why Mr. Zhang Feiyang and Mr. Zhang said just now that 'vehicle-road collaboration' is more dependent on 5G than 'remote intervention'."

Hu Lai didn't ask a question just now, but he completely figured it out at this moment.

"Vehicle-road collaboration" is actually a large-scale application scenario under 5G network. Its technical difficulty is not high, but it relies on network transmission abnormally.

The meaning of subtext is that cities without 5G coverage should not be popularized at all.

really.

Not beyond the expectation, Zhang Feiyang, who was standing beside him, looked at Hu Lai and Director Zhang, and added:

"Boss, in fact, although we have developed the 'vehicle-road collaboration' technology, to use the 'vehicle-road collaboration' technology, we not only need to have a 5G network, but also have a large amount of 'road informatization' data."

"Even our mountain city, the most important roads in the city have realized 'road informatization', so the current 'vehicle-road collaboration' function can only be considered half of the function."

"but……"

"Because 'unmanned bus' is not like family cars, the 'unmanned bus' route is relatively fixed, so we only need to realize 'road informatization' on the roads on the bus route, and we can also realize 'vehicle-road collaboration' technology

.”

"We can also take advantage of the opportunity of this 'unmanned bus' delivery. If we can convince the city to build a 'vehicle-road collaboration' system for mountain cities, it will be a win-win business for us."

"It can not only make some money, but also gain experience in the construction of the 'vehicle-road collaboration' system!"

Zhang Feiyang returned to the topic of "unmanned bus". Hu Lai also understood Zhang Feiyang's plan and nodded without any objection.

Hu Lai did not continue to talk about the "vehicle-road collaboration" technology. His main purpose of coming today was to understand "unmanned bus". After listening to the introduction, he remembered the problems of solar panels and "steering wheelless" modes.

After pondering for a moment, he said:

"Feiyang, I have heard so much, so I'll give you a suggestion."

Everyone looked stunned and looked at Wu Lai.

"The problem of using solar panels for cars at the beginning. To be honest, I don't know if solar panels will be used in cars in the future."

"Maybe the battery life will increase and the charging efficiency will be higher in the future, and solar panels will become useless and will be completely launched into the automotive market; of course, it is also possible that solar panels will generate electricity more and more costly while increasing the cost, and will gain more and more favor from buses and buses.

”

"Just like when we use solar panels now, if the cost of 50,000 yuan is reduced to 20,000 yuan, then we can get the money back in three years, which is very cost-effective for bus companies; if the cost is reduced to 10,000 yuan, or 30 yuan can be charged a day

If you have electricity, it will inevitably become a popular technology.”
