Recently, the "Blue Book of Intelligent Connected Vehicles 2023-2024", referred to as "Blue Book" for short, jointly initiated by China Association of Automobile Engineering, National Innovation Center for Intelligent Networked Vehicles and China Innovation Alliance for Intelligent Networked Vehicle Industry, and compiled by relevant domestic units in the field of intelligent networked vehicles was officially released. As a benchmarking enterprise in the cloud control infrastructure industry chain, Sirun has been deeply involved in its compilation work for four consecutive years.

As one of the core members in the intelligent connected vehicle industry, Sirun has actively participated in compiling the "White Paper on Integrated System of Vehicle-Road-Cloud"  and the"Blue Book on Intelligent Connected Vehicles 2022".

In this process, we provide detailed descriptions, clear definitions and scientific classifications of the research progress and application of key supporting equipment in the integration of vehicle-road cloud - onboard terminals; It also conducts professional summarization and standardized processing of the research and development progress and application status of protocol stacks; At the same time, it also actively participates in describing and defining the characteristics and overall architecture of cloud control basic platform to promote continuous progress in standardization construction of cloud control platform. These efforts not only significantly improved the performance and security of the platform system, but also provided solid technical support and strategic contributions for the overall promotion of vehicle-road-cloud integration.

The compilation of the intelligent network blue book that Sirun participated in this time focuses on traffic management applications, subdividing four application scenarios: digital traffic signs, traffic signal control, traffic information release and traffic warning. Specific technical requirements are proposed for each scenario, including information coding, scope of information release, direct communication delay, etc., providing strong support for the standardized development of intelligent connected vehicles.

Introduction to Blue Book

Solid Foundation and Years of Accumulation
The Blue Book on Intelligent Connected Vehicles is the first annual research report in China dedicated to discussing the development of the intelligent connected vehicle industry. It was first published in 2018 and has now been issued six times, with over a hundred articles published and nearly a thousand experts participating. It has created multiple sustainable research systems focusing on industries, technologies, policies, standards, demonstrations, etc., and has become a well-known authoritative work in the field of intelligent connected vehicles in the industry.

Stay Up-to-Date with Hot Topics and Advance with the Times
The Blue Book 2023-2024 fully embodies the three principles of "comprehensiveness, pertinence, and depth" in its preparation. In terms of comprehensiveness, the book has five chapters, including general report, industry, regulations and standards, technology, and special topics and hotspots, with a total of 23 reports, systematically discussing the latest status and development trends of the intelligent connected vehicle industry, technology, policies, standards, and demonstrations in the past year; In terms of pertinence, the book includes many reports that discuss industry hot topics such as "industrial clusters, vehicle-road-cloud integration, testing and demonstration, high-precision maps, cloud control platforms, intelligent cockpits, testing and evaluation, data security compliance". In terms of depth, a special hot topic section is set up to systematically discuss issues related to the safety of intelligent connected vehicles, focusing on data security, network security, functional safety, and expected functional safety.

Collaborative Efforts in Co-authoring

Blue Book 2023-2024 adheres to high starting point thinking and high standard writing, taking the responsibility of playing a role as an exchange and cooperation platform for domestic and foreign intelligent connected vehicle industry. After one year's preparation, it has gathered more than 90 units from domestic and foreign OEMs, parts companies, technology companies, industry institutions, research institutes and universities, with nearly 200 experts working together to complete it. It aims to summarize experience in the development of the industry and provide suggestions for government departments, production enterprises, research institutions and other organizations.

Sirun Participated

During the preparation of this Blue Book, Sirun is responsible for the writing of the traffic management application section. We have segmented four major application scenarios for digital traffic signs, traffic signal control, traffic information dissemination, and traffic warning, and have proposed specific technical requirements for each scenario, including information encoding, information dissemination scope, communication latency, and so on.

1）Digital traffic sign scenarios
Definition:
The information coding for digital traffic sign scenarios should consist of location, scope of application, effective time, traffic sign and marking information, and verification information.
Technical requirements:

• It should support the release of traffic information to all intelligent connected vehicles within its coverage area;
• The pre-positioning distance for information release should be set based on factors such as the volume of information to be conveyed, the type of information, and the performance of information transmission, to meet the time requirements for autonomous vehicles to recognize and respond;
• The direct connection communication delay of security applications should not exceed 200ms.

2）Traffic signal control scenarios
Definition:
Traffic signal control scenarios include intersection traffic signals, lane traffic signals, ramp traffic signals, tunnel traffic signals, and emergency lane signals.
Technical requirements:

• Traffic signal control facilities send data such as the current working status of signal lights, phase lists, and timing of each phase status through their own wireless communication modules or external communication interfaces in real time;
• The latency of direct communication in the application scenario should not exceed 50ms.

3）Traffic information release scenarios
Definition:
The traffic information release scenarios mainly include scenarios such as trusted information and variable speed limits.
Technical requirements:

• The traffic information release facilities send traffic conditions, traffic control, traffic speed limits, traffic guidance and prompts, etc. through their own wireless communication modules or external communication interfaces;
• The latency of direct communication in the application scenario should not exceed 200ms.

4）Traffic warning scenarios
Definition:
The traffic warning scenarios mainly refer to the traffic safety warning scenario of dangerous road sections.
Technical requirements:

• Traffic warning facilities send information such as warning location, warning range, warning content, and warning effective time through their own wireless communication modules or external communication interfaces;
• It needs to have an extensible on-site warning function that can receive and publish information transmitted by emergency vehicles.
• The latency of direct communication in the application scenario should not exceed 50ms.
