Standards Description and Impact

GB 45672-2025 In-vehicle Emergency Call System

The in-vehicle emergency call system can be automatically activated through internal vehicle strategies when an accident occurs or manually triggered by occupants to synchronize the vehicle's location and relevant status information to an emergency call service platform and establish two-way voice communication. This standard applies to M1 and N1 vehicles and covers general requirements, location information requirements, network connection requirements, triggering requirements, information and functional requirements, hands-free call performance requirements, shock resistance requirements, and electromagnetic compatibility requirements for AECS. The popularization of in-vehicle emergency call systems can effectively shorten accident response times, provide timely and effective medical assistance to injured accident victims, and restore road order as quickly as possible, thereby significantly improving the efficiency of treating injured traffic accident victims. It is poised to become an effective measure to reduce casualties in road traffic accidents in China.

GB/T 32960.3-2025 Technical Specifications for Remote Service and Management System of Electric Vehicles - Part 3: Communication Protocols and Data Formats

‌Scope of Application‌: It stipulates the protocol structure, communication connections, data packet structures and definitions, and data unit formats and definitions in the remote service and management system for electric vehicles. It applies to platform-to-platform communications in such systems, with on-board terminals to platform transmissions preferably following for reference.

‌Mandatoriness‌: It is a recommendatory standard. However, within the electric vehicle remote service and management system, to achieve effective communication and data sharing between different platforms and terminals, the industry typically follows this standard to ensure system compatibility and interoperability.

‌Standard Impact‌: This standard elaborates on communication protocols and data formats, covering communication processes, data encoding, transmission methods, etc., between vehicles and remote service platforms. By unifying communication protocols and data formats, it enables interoperability between vehicles from different manufacturers and service platforms, enhancing data exchange efficiency and accuracy. The implementation of this standard promotes information sharing and collaborative development in the electric vehicle industry, driving the entire industry's digitalization process.
