Mandatory National Standard on Security Requirements for Intelligent Connected Vehicles Combination Driving Assistance Systems Released.

Recently, the Ministry of Industry and Information Technology organized the development and coordination of the mandatory national standard "Safety Requirements for Intelligent Connected Vehicles Combination Driving Assistance Systems" (GB 47955-2026), which was approved and issued by the State Administration for Market Regulation and the National Standardization Management Committee. It is planned to be officially implemented starting from January 1, 2027. The combination driving assistance system refers to a system that assists the driver in executing lateral and longitudinal vehicle control under specific design and operating conditions, while the driver continues to observe traffic conditions and control the vehicle. In recent years, a new round of technological revolution and industrial transformation has been deepening, driving profound changes in the form of auto products, usage modes, business models, etc. The intelligent connected vehicle industry in China has entered a period of rapid development. Since 2026, the penetration rate of new passenger cars equipped with combination driving assistance functions in China has reached 70%, with over 30% of them equipped with Navigation On Autopilot (NOA) function. The Ministry of Industry and Information Technology attaches great importance to the development of the intelligent connected vehicle industry, and has successively formulated two versions of the intelligent connected vehicle technical standard system, and issued and implemented a batch of urgently needed standards such as information security, software upgrade, automatic driving data recording system. Building on the previous release and implementation of recommended national standards for single-lane driving control, multi-lane driving control, and other combination driving assistance systems, the Ministry of Industry and Information Technology has organized the National Vehicle Standardization Technology Committee to initiate the development of the mandatory national standard "Safety Requirements for Intelligent Connected Vehicles Combination Driving Assistance Systems" starting from 2024. The "Safety Requirements for Intelligent Connected Vehicles Combination Driving Assistance Systems" is based on China's industrial development and industry regulatory needs, emphasizing technical feasibility, product compatibility, and practical implementation, and proposes a comprehensive and adaptable safety index system that is clear and comprehensive. Firstly, it fully considers different product forms and technological routes, and puts forward applicable safety requirements for three types of combination driving assistance systems - basic single-lane driving, basic multi-lane driving, and navigation driving assistance. Secondly, considering China's road traffic characteristics, it sets out basic requirements for ensuring the safe operation of combination driving assistance systems from the perspectives of functional requirements, data recording, and vehicle manufacturer safety guarantees. Thirdly, considering the core positioning of the system as "driving assistance," it proposes user requirements and operational aspects such as human-machine interaction, user instructions, and user training, providing a basic guarantee for the correct coordination between users and the system. Fourthly, considering the actual needs of China's industry management, a multi-level evaluation method including field tests, road tests, document inspections, etc., has been established to comprehensively assess the safety capabilities of the system. At the international regulatory level, the United Nations World Forum for Harmonization of Vehicle Regulations (WP.29) issued the technical regulation "Unified Regulation on Approval of Vehicle Driver Control Assistance Systems (DCAS)" (UN R171) for combination driving assistance systems in March 2024, and completed the first revision in March 2025. It proposes unified technical requirements for functions, human-machine interaction, fault response, etc., and specifies supporting testing and verification methods, in-use supervision, certification procedures, etc. Compared to UN R171, the Chinese standard puts forward more detailed technical requirements in terms of system design and operation scope, functional requirements, driver state detection, user notification, etc., while adding some testing scenarios and corresponding testing processes and acceptance criteria, and clarifying the supporting inspection and testing methods for the proposed technical requirements. While maintaining consistency in core technical content, it is more in line with the complex road traffic environment in China and the actual needs of industry management. The issuance and implementation of the "Safety Requirements for Intelligent Connected Vehicles Combination Driving Assistance Systems" establishes a clear and unified safety standard for combination driving assistance systems, which is of great significance for improving the safety level of intelligent connected vehicles and ensuring the healthy and sustainable development of the industry. In the next step, the Ministry of Industry and Information Technology will diligently promote the implementation of the standard, strengthen the management of access to intelligent connected vehicle products, further clarify the safety responsibilities of enterprises, ensure the safe and compliant application of combination driving assistance systems, accelerate the release and implementation of other mandatory national standards such as automatic driving systems, promote the construction of a comprehensive intelligent connected vehicle standard testing and regulatory system, accelerate the industrialization of automatic driving technology, and lead the high-quality development of China's intelligent connected vehicle industry.
