This document defines the requirements for connected-vehicle onboard units for vehicles ranging from bicycles to light duty vehicles, buses, emergency vehicles, and heavy commercial vehicles. It addresses multiple mandatory and optional interfaces, including V2X and other wireless interfaces. Additional interfaces that support security and in-vehicle communications are also addressed. The scope further includes multiple architecture options and corresponding application, hardware and security requirements. An Onboard Unit focused J2735 ASN.1 build is also distributed in concert with this document to ensure interoperable data exchange and data structures for information exchanged with other OBUs and Roadside Units. OBU developers and users will be able to directly apply this document to conformance certification programs, and security certificate authorities will be able to use it for the purpose of issuing certificates to trusted OBUs.
