LTE-V2X Requirements and Deployment Profiles for Aftermarket V2X Devices (AVD)
J3315
This SAE Standard describes classes of AVDs intended to support particular services, provides their respective requirements including RF performance requirements, specifies their respective profiles, and describes the test procedures. This document is targeted to enable early deployments by supporting different classes of AVDs that could interact with on-board units (OBUs) and roadside units (RSUs). Users of this document would include manufacturers of vehicles and micro-mobility devices, developers of hardware and applications, as well as those interested in LTE-V2X system architecture, testing, and certification.
This standard therefore defines LTE-V2X PC5 sidelink (mode 4) that can be used with several variants of AVDs, spanning non-integrated devices (which might not need lane-level accuracy) through deeply-retrofitted devices (which might approach the capability of factory-integrated devices). Additionally, this standard provides guidance on how to discern and quantify the limitations of AVDs, promoting transparency and trust in their functionality.
Rationale: SAE J3161/1 defines on-board requirements and profile for a V2V safety solution, applicable to light duty and emergency vehicles, and SAE J3161 defines a radio profile for V2V, V2I, and I2V communication in Channel 183. The missing link is aftermarket safety devices (AVDs) which per scope defined for this WIP includes different classes and capabilities and need to be differentiated from on-board, integrated devices from security services and data confidence perspectives, the latter since the BSM from AVDs may not be connected to in-vehicle networks. By providing a framework for ASD deployment and enhancing interoperability, this standard plays a pivotal role in increasing the LTE-V2X penetration and furthering the adaptation of advanced safety technologies on our roads.
