SAE International Levels of Driving Automation

Overview#

SAE International Levels of Driving Automation Issued January 2014, SAE international’s J3016 provides a common taxonomy and definitions for automated driving in order to simplify communication and facilitate collaboration within technical and policy domains. It defines more than a dozen key terms, including those italicized below, and provides full descriptions and examples for each level.

The report’s six levels of Autonomous Automobile driving automation span from no automation to full automation. A key distinction is between level 2, where the human driver performs part of the dynamic driving task, and level 3, where the automated driving system performs the entire dynamic driving task.

These levels are descriptive rather than normative and technical rather than legal. They imply no particular order of market introduction.

Elements indicate minimum rather than maximum system capabilities for each level. A particular vehicle may have multiple driving automation features such that it could operate at different levels depending upon the feature(s) that are engaged.

System refers to the driver assistance system, combination of driver assistance systems, or automated driving system. Excluded are warning and momentary intervention systems, which do not automate any part of the dynamic driving task on a sustained basis and therefore do not change the human driver’s role in performing the dynamic driving task.
