Definitions for Terms Related to Automated Driving Systems Reference Architecture
The terms and definitions in this document describe the functions performed within an ADS, as defined in SAE J3016. Where possible we have attempted to capture the language that is already in use within the automated driving development community. Where needed, we have added new terms and definitions, including clarifying notes to avoid ambiguity. SAE J3131 deals primarily with Level 4 and Level 5 ADS features.
This SAE Recommended Practice provides a reference functional architecture and describes the functional components and relationships between them of a typical on-road automated driving system (ADS) software architecture, as well as providing related terms and definitions. This SAE Recommended Practice does not provide specifications, or otherwise impose requirements on, the development of ADSs.
This document has been developed according to the following guiding principles, namely, it should:
Be descriptive and informative rather than normative.
Provide functional definitions.
Be consistent with current industry practice.
Be consistent with prior art to the extent practicable.
These functional definitions build upon definitions developed by the National Institute of Standards and Technology (NIST) and attempt to reflect the language as it is currently used within the ADS development community.
Vehicle to vehicle (V2V)
Intelligent transportation Systems
Driver assistance systems
