5Safety Treatment in V2X Applications
Contents
1. Introduction
This White Paper describes the new challenges in the treatment
of functional safety arising from the introduction of connected
and distributed functions, which are typical for cellular vehicle-to-
everything (C-V2X) applications.
A dedicated 5GAA technical working group performed a detailed
analysis to determine, propose, and evaluate possibilities for
mobile network operators, vendors, and any further identied
stakeholders to provide vehicle original equipment manufacturers
(OEMs) what they need to treat safety in new use cases enabled by
C-V2X technologies. These new use cases include scenarios beyond
those considered in the ISO 26262 standard [1], which assumes
that the functional safety treatment is limited to the perimeter of
a single vehicle and does not consider any C-V2X communications
with functional parts outside the vehicle.
For the analysis, it was decided to study representative safety
requirements for two selected use cases that well cover the relevant
C-V2X scenarios of network-based information delivery and direct
communication:
• V2N-enabled Tele-operated Driving (ToD)
• V2V-enabled Emergency Brake Warning (EBW)
In these use cases, the concurrent presence of multiple vehicles,
communication means, remote operation, and infrastructure
elements generates multiple safety design options, creating
dierent classes of challenges that can be solved in dierent ways
by dierent safety engineers.
This white paper summarises the analysis available in the 5GAA
Technical Report [2]. The paper also provides some possible
solutions (proposals) for addressing the related challenges. Further,
those proposals could become guidelines for the safety design of
connected and distributed functions, and at the same time open new
standardisation work streams for extending existing specications
and procedures.
