SAE J3161/1_202409

This SAE Standard specifies system requirements for an onboard vehicle-to-vehicle (V2V) safety communications system for vehicle classes of 2, 3, 4, and 51, including standards profiles, functional requirements, and performance requirements. The system is capable of transmitting and receiving the SAE J2735-defined basic safety message (BSM) over a PC5 Sidelink V2X (mode 4) communications link as defined in ETSI Release 142,3. The system uses Institute of Electrical and Electronics Engineers (IEEE) 1609 standards for network and transport layer communciations, as well as security. SAE J3161/1_2022-03 is the first edition of the SAE Standard for onboard system requirements for V2V safety communications using LTE-V2X Sidelink. It provides information necessary to build interoperable systems that support select safety applications, which rely on the exchange of basic safety messages. The initial March 2022 version of the standard was the culmination of work that began in December 2017. This revision of the standard provides clarifications, fixes errata, and specifies new features that enhance the quality of the document and improve the performance of the V2V safety communications.
