汽车驾驶辅助系统领域首个强制性国家标准发布 一图读懂

Core Viewpoint - The mandatory national standard "Technical Requirements and Test Methods for Automatic Emergency Braking Systems for Light Vehicles" (GB 39901-2025) will be officially implemented on January 1, 2028, aiming to enhance road traffic safety in China through the promotion of advanced driving assistance technologies [1][3]. Summary by Sections Standard Implementation Timeline - The revision process for the standard began in June 2022, with various stages including research, drafting, and validation tests leading up to the final publication in December 2025 [4][5]. System Functionality and Requirements - The AEB system is designed to issue warning signals and automatically engage the vehicle's braking system to reduce speed, thereby avoiding collisions or mitigating their consequences. By 2025, over 60% of new passenger cars in China are expected to be equipped with AEB systems [3][5]. - The standard specifies general requirements, performance requirements, and testing methods for M and N class vehicles, including collision warning, emergency braking, and system robustness [5][10]. Performance and Testing Enhancements - The new standard expands the activation speed range for AEB systems, requiring effective responses to vulnerable road users such as pedestrians and cyclists within specified speed intervals [7][10]. - The number of typical scenarios for testing AEB systems has increased from three to six, and the number of misactivation test scenarios has expanded from two to five, enhancing the system's reliability [10][12]. Safety and User Guidance - Manufacturers are required to provide comprehensive documentation regarding the AEB system's functionality, limitations, and user instructions to ensure proper usage by drivers [13]. - The standard mandates that the AEB system must be capable of responding to various target types and speed ranges, ensuring a broader application in real-world scenarios [10][14]. Implementation Deadlines - New vehicle models must comply with the standard by January 1, 2028, with full compliance for all vehicle types by January 1, 2030 [14].
