During the National Two Sessions this year, representatives and committee members of the automobile industry put forward a number of motions, suggestions and proposals related to intelligent networked vehicles to guide the development of intelligent networked vehicles to speed up. In recent years, my country's intelligent networked automobile industry has developed rapidly, and the ability to develop and test vehicles of L2 and above has initially formed. Commercialization and application landing have also entered the exploratory stage, and safety issues have become the focus of the next step in popularization.

On May 29, the inauguration meeting of the Intelligent Connected Vehicle Expected Functional Safety Working Group (hereinafter referred to as the "Working Group") of the China Intelligent Connected Vehicle Industry Innovation Alliance was held at the National Intelligent Connected Vehicle Innovation Center. Li Jun, academician of the Chinese Academy of Engineering, chairman of the Chinese Society of Automotive Engineering, chairman of the China Intelligent Connected Automobile Industry Innovation Alliance, director of the National Intelligent Connected Automobile Innovation Center, and Tsinghua University professor Li Jun serves as the leader of the expected functional safety working group.

Why set up a working group for expected functional safety? What is the current development status of my country's intelligent networked vehicles in the security field? What significance does the establishment of this academician-led working group have to promote the development of intelligent connected vehicles?

A reporter from "China Automobile News" exclusively interviewed Li Jun and asked him to answer the above questions in detail.

Anticipating functional safety is the biggest problem in the R&D and commercialization of intelligent connected vehicles

It is understood that due to the existing design level, communication technology, sensor technology and other related technical limitations, functional safety, information security, and expected functional safety have become the three major obstacles to the rapid development of intelligent driving. Li Jun pointed out that expected functional safety is the biggest problem in the development and commercialization of intelligent connected vehicles. Compared with relatively mature functional safety research and information security research that has achieved certain research results, it is expected that functional safety research is still in the conceptual stage.

With the joint release of the "Autonomous Driving Safety First White Paper" by 11 companies in the automotive and travel field last year, and the release of the UL 4600 "Autonomous Driving Product Safety Evaluation Standard" in the United States this year, the safety issues of intelligent networked vehicles have increasingly caused global auto manufacturers Wide attention.

In Li Jun's view, compared with traditional automobile powerhouses such as Germany, the United States, and Japan, the development of China's automobile industry started late. For the emerging intelligent connected cars, safety is the first. Chinese auto manufacturers not only need to quickly learn and master the experience and technology of traditional car safety, but also actively research and explore new problems in the safety of intelligent networked cars, including expected functional safety, functional safety and information security. This poses a big challenge to the personnel and resource input of the Chinese automobile industry in terms of safety.

In addition, my country's high population density, unreasonable urban layout, and mixed traffic have brought new difficulties to the technical research of intelligent networked vehicles. Li Jun emphasized that, especially in the field of expected functional safety, the challenges my country faces are extremely severe.

At the same time, the relevant safety standards adapted to China's special national conditions are not yet complete, especially the expected functional safety standards are still being explored in the category definition and evaluation system. Li Jun said that Chinese automakers must not only closely follow foreign advanced standards and technologies in terms of safety, but more importantly, develop an intelligent network that meets China’s national conditions in accordance with my country’s actual road traffic, policies and regulations, and traffic participants’ behavior and habits. Automotive safety standards and technologies.

Promote the development of expected functional safety standards

Li Jun pointed out that standards and regulations must be adopted to ensure the operational safety of intelligent networked vehicles.

So, what is the current development of the global intelligent networked vehicle in terms of safety-related standards and regulations?

In fact, many countries around the world are at a similar stage of development in terms of standards and regulations related to the safety of intelligent connected vehicles. Li Jun introduced:

First, the current safety-related standards and regulations of intelligent networked vehicles at home and abroad are still in the early stages of development. Although the functional safety-related standard ISO 26262 has been applied, the most important information security and expected functional safety of intelligent networked vehicles are The international standard has not yet been finalized and is still under global discussion and solicitation of opinions;

Second, compared to information security standards, expected functional safety is in the research and exploration stage whether it is in research methods, development processes, or test specifications. Research institutions in the United States and ISO are organizing the formulation of relevant standards, but they are currently in the draft stage and have not been officially released or applied on a large scale. Currently, the more influential expected functional safety standards are ISO 21448, UL 4600, etc.

Third, while China is closely following and actively participating in the formulation of international expected functional safety standards, it is also actively advancing the formulation of relevant standards in light of China's situation. One of the goals of the newly established working group is also to promote the formulation of my country's expected functional safety standards, and to promote the better implementation of intelligent networked vehicles that meet the expected functional safety in China.

Four goals are committed to breaking through core key technologies

According to Li Jun, there is little gap in the start of research in the field of safety among countries around the world. In particular, the expected functional safety direction of intelligent networked vehicles is a new challenge for global automakers. It is especially worth mentioning that my country's intelligent networked vehicles still have a certain gap compared with foreign manufacturers in terms of data accumulation and development and testing tools.

How to ensure the development of my country's intelligent networked vehicle safety has become a common issue in the industry.

The establishment of this working group is to respond to the safety requirements of intelligent connected vehicles, and integrate domestic superior government, production, academic, research, and user units, combined with international planning, to build the expected functional safety of domestic intelligent connected vehicles R&D and testing systems, breakthrough core key technologies, build domestic and foreign cooperation and exchange platforms, and promote the enhancement of the overall R&D strength of functional safety expected by the industry.

In summary, the specific objectives of the expected functional safety working group can be summarized into the following four aspects:

Promote the construction of expected functional safety test and evaluation system

Promote research and innovation of anticipatory functional safety technology

Organize and promote my country's testing and verification system and capacity building

Form large databases, scene libraries and standards related to expected functional safety.

Li Jun said that the working group will develop key technologies for the expected functional safety of intelligent connected vehicles and formulate specific technical indicators to promote the healthy and sound development of the intelligent connected vehicle industry. At the same time, regular domestic and international exchange meetings will also be organized to promote in-depth exchanges and efficient collaboration among groups and organizations related to the expected functional safety of intelligent networked vehicles at home and abroad.

In Li Jun's view, compared with foreign automakers, my country not only has great advantages in policy support, but also we can gather the power of upstream and downstream enterprises in the national auto industry to realize China Improve the overall safety performance of intelligent networked vehicles. For my country's automobile industry, this is an opportunity for the development of the times, and it is also a arduous challenge. We still have to be full of confidence.
