Intelligent network connection makes you closer to the future

China Consumer News·China Consumer Network Report (Reporter Wu Bofeng) Automated driving vehicle with multiple sensors, smart cockpit with private customized service, intelligent transportation system based on real-time road condition information... 2019 held in Beijing not long ago At the World Intelligent Networking Auto Conference, many new species have opened the eyes of the audience.

In the exhibition space of more than 50,000 square meters, smart cars, smart transportation, new energy vehicles and other exhibits are full of science and technology. The good news is that these “big and up” technology products are gradually approaching our daily lives.

Intelligent network is the future development trend

How far is intelligent life from us?

As a technical conference in the automotive field, the World Intelligent Networking Auto Conference has answered the doubts in people's minds through the presentation of various travel scenes.

From the Asian Consumer Electronics Show to the 2019 World Internet Conference, to the current World Intelligent Networking Automotive Conference, this year, the development of the future transportation and travel market has been the focus of attention from all walks of life.

At the 2019 World Intelligent Networking Auto Conference, the reporter saw that both traditional auto companies and new power vehicles, whether they are independent brands or joint venture brands, will focus on the future development of automotive intelligent network.

The industry has shown great enthusiasm for this, and ultimately it is rooted in the needs of consumers. People are not satisfied with the traditional way of travel, and hope that the car will follow the trend of the times and upgrade to a new height.

To this end, the major car companies have concentrated on exhibiting vehicles with intelligent network technology. Many of the new cars on display are equipped with a roof lidar. The vehicles can identify the participants on the road through the laser radar and camera, and display them in real time on the screen inside the car.

Many consumers think that intelligent networked cars are not automatic driving technology? What new tricks can there be?

Indeed, due to the limited technical level, the products currently on the production models are more in the public view, but this is not the highest level of intelligent networked cars.

Li Deyi, an academician of the Chinese Academy of Engineering, said that intelligent network technology is a disruptive technology that reshapes the future, and will change people's lifestyles and even determine the development model of some enterprises.

The development of technology is closely linked to changes in the external environment.

With the commercialization of 5G and artificial intelligence, the intelligentization of the automotive industry is gradually maturing under the dual promotion of the market and technology.

An Hui, deputy chief engineer of the China Electronics and Information Industry Development Research Institute, said that the automobile and information technology are accelerating integration. In the future, the car itself will become a smart terminal with four wheels, and the value of information technology will be more and more manifested in the car.

Smart life is not just a smart car

“You just need to sit in this cockpit and drive in the usual way, you can start an unmanned car that is dozens of kilometers away. The vehicle trajectory will be placed on the screen in front of you.” Waiting in front of China Mobile booth Experience the growth of 5G remote assisted driving unmanned vehicles.

According to the instructions of the staff, the reporter used various instructions such as speed increase, braking and turning to test the remote driving technology, and the vehicles were successfully completed. During the entire test period, the vehicle's driving trajectory was in the same frequency as the reporter's operation command, and no delay occurred.

Liu Heng, senior project manager of China Mobile Zhixing Network Technology Co., Ltd., said in an interview with the reporter of China Consumer News that the previous 4G network technology has also been tested with the same difficulty, but the vehicle cannot be networked due to low bandwidth and high latency. Accurate operation, only considering the safety factor can only be done. The 5G technology solves the above problems well, making remote control of driving vehicles a reality.

In his view, the 5G era will give mobile operators more opportunities to join the upgrade process of travel services.

A lot of consumers familiar with the US group take-outs also appeared in the exhibition hall. Although with the development of mobile Internet technology, take-out is rapidly spreading in people's lives, but a take-away platform service provider appears in the scene of the networked car conference known for its intelligent technology, which is somewhat awkward.

The reporter learned that the unmanned takeaway car being developed by Meituan Takeaway is a successful case of 5G commercialization technology. This small-sized take-away car can not only complete the basic services such as daily meal taking and meal delivery, but also complete the accurate delivery and climbing functions under the Internet big data application conditions, so that consumers can experience no without leaving the house. The convenience of people taking out.

In addition, short-distance vehicles such as park buses and community shuttle buses have also emerged as a highlight. They are not only closely related to the Internet of Things, but also have many functions that are not configured in traditional cars. For example, the remote air conditioner starts, and the driving mode is changed according to the weather, which reflects the "smart" expression of the smart car according to the actual use situation.

"Car Road Collaboration" helps solve traffic problems

Faced with the development trend of informationization today, traditional transportation technologies and means have not adapted to the needs of modern social development.

The intelligent transportation system is undoubtedly the development direction of the future transportation system. It effectively integrates advanced information technology, data communication transmission technology and electronic sensing technology into the entire ground traffic management system, and has a real-time, accurate and efficient integrated transportation management system. According to the research report of China Automotive Industry Development (2019), after using intelligent transportation technology to improve road management, the number of traffic accident deaths per year can be reduced by more than 30%, and the utilization rate of vehicles can be increased by 50%.

For this reason, current auto companies and even communication operators attach great importance to this field, and have increased market input and promoted rapid development in this field.

The era of intelligent networking requires vehicles to become smarter and puts the same demands on the road. "Car-way collaboration" is a new development path that can be extended by autonomous driving technology.

At present, many cities in China, including Beijing, Shanghai, and Chongqing, are conducting intelligent network road testing. Since 2018, Beijing has opened more than 20 test roads, and the accumulated test mileage has reached 730,000 kilometers.

When the road becomes "smart", the vehicle can gain early insight into the road conditions ahead, which provides more possibilities for further alleviating traffic congestion and reducing traffic safety accidents.

In the current domestic auto market, even some models with rich configuration are only equipped with a 360-degree panoramic camera, which can realize the monitoring of the environment within a few meters around the vehicle, far less than the distance predicted by the road ahead of several kilometers.

Liu Heng said that when the vehicles and roads are coordinated, the vehicle can know the traffic flow and obstacles in front of the road in advance, especially for some emergencies, which can ensure that the vehicle chooses the most suitable route. by.

Data security requires standard specification guarantee

While a large number of data applications can support vehicles to be intelligent, how to protect data must be another focus.

Safety is the guarantee for the coordinated development of automobiles, transportation and the city as a whole. In the digital age, security guarantees cover two aspects: traffic safety at the traditional level and information security at the digital level. The traditional level of traffic safety mainly includes the prevention of traffic accidents. The main and passive safety technologies of vehicles have been accumulated deeply, and will change with the changes of the form of intelligent network vehicles in the future. As for the digital level, due to the complexity of the collaborative system between several, with the continuous development of its networked and collaborative processes, information security has gradually become the core issue of system evolution.

Li Keqiang, a professor at the Department of Automotive Engineering at Tsinghua University, said that the development of intelligent networked vehicles will inevitably involve a large amount of data and signal transmission, and in signal distribution, 5G standardization, unification of communication frequencies, innovation and platformization of communication technologies, etc. In-depth collaboration is also needed in all sectors of society. At the same time, all parties should carry out research to adapt to the domestic vehicle road coordination life cycle information security management standards, technical standards and safety test evaluation standards, and gradually form enterprise and industry standards and norms.
