SAC/TC114 Completes the First Test and Verification for “GB/T Technical Requirements for LTE-V2X Direct Communication-based On-board Telematics Systems


From January 6 to 10, 2020, the Technical Sub-committee of Intelligent Connected Vehicles (ICV) under the National Technical Committee of Auto Standardization (SAC/TC114) carried out the verification tests for the recommended national standard “GB/T Technical Requirements for LTE-V2X Direct Communication-based On-board Telematic Systems” (hereinafter, the “LTE-V2X Telematic Standard”)in Tianjin.


The LTE-V2X Telematic Standard will be the first interconnectivity standard in the ICV area. It specifies the system requirements for onboard direct communication telematic systems, including the requirements for the access layer, the network layer, the application layer and the corresponding testing methods.


During the first phase of the test and verification work for the standard, the requirements on components were tested and verified, especially the component-class protocol conformance and components related to communication security, system radio-frequency performance, system positioning, message sending, etc. Based on the results of this test, the secretariat of the sub-committee and the project group decided to carry out the next test and verification from February 10 to 14, 2020, for requirements on vehicle-class performance.


In the “Guide on Developing the National Internet of Vehicles (IoV) Standards System” jointly issued by MIIT and SAC in 2018, LTE-V2X is adopted as a key technology for wide area, medium and short-range IoV, and the ICV standards system is put forward as one of five sub-systems of the national IoV standards system. In another policy document: “Action Plan for Developing the Internet of Vehicles (Intelligent Connected Vehicles) Industry”, which was released by MIIT in late 2018, it is required to cover LTE-V2X on major roads and expressways in some cities, to carry out 5G-V2X application for demonstration purposes, and to enhance the rate of user penetration of IoV to more than 30% by 2020.


To support the implementation of these government policies and promote the development of the IoV (ICV) industry, standardization organizations that used to be in different sectors are included in the construction of the national IoV standards system, such as SAC/TC114 on automotive, SAC/TC485 on communication, SAC/TC260 on cybersecurity, SAC/TC268 on intelligent transportation, etc. As the main automotive standardization force, SAC/TC114 established the ICV Sub-committee, specializing in developing standards for the ICV standards system. At present, the sub-committee has set up a number of working groups for different aspects of ICV standardization, such as ADAS, information security, automatic driving, ICV function and applications, electromagnetic compatibility, etc.


The LTE-V2X Telematic Standard was developed by the ICV Function and Application Working Group, whose standard and research projects also include: “Road Vehicles – Methodology of Connected Vehicles”, “Research on Standardization Requirements for the Information Interaction Function Between Intelligent Connected Vehicles and Mobile Terminals”, and “Research on Classification and Standardization Requirements of ICV Message Sets”.
