STANDARDS &
COMMITTEES
ISO collaboration to update SAE Recommended
Practice regarding driving automation
With the rapid advancement of
driving automation, SAE
International, in collaboration
with the International
Organization for Standardization
(ISO), announced today an
important update to the
industry's most-cited reference
for driving automation
capabilities: SAE J3016
Recommended Practice:
Taxonomy and Definitions for
Terms Related to Driving
Automation Systems for OnRoad
Motor Vehicles,
commonly referenced as the
" SAE Levels of Driving
Automation. " SAE J3016
provides a taxonomy with
supporting terms and definitions
for SAE's six levels of driving
automation. The SAE Levels
range from no driving
automation at Level 0 to full
driving automation at Level 5, in
the context of motor vehicles
and their operation on roadways.
This latest update to SAE's
Levels of Driving Automation
refines the previous version of
the Recommended Practice with
the addition of several new
terms, substantial refinement
28 June 2021
and clarification of misinterpreted concepts, and
restructuring of certain definitions into more logical
groupings. Notable changes to this version of the
Recommended Practice include:
* Further clarity on the differences between SAE Level
3 and SAE Level 4, including the role of the fallbackready
user, the possibility of some automated
fallback at SAE Level 3, and the possibility of some
alerts to in-vehicle users at SAE Level 4.
* Additional terms and definitions for two distinct
remote support functions: remote
assistance and remote driving, as well as the users
who perform those functions: remote assistant and
remote driver.
* SAE Level 1 and 2 driving automation systems have
been given the name " Driver Support Systems " as a
counterpart to the term " Automated Driving
Systems " used for SAE Levels 3-5.
* Explanation for how classifications of sustained
Automated driving is rapidly expanding, and SAE International is helping
lay the foundation for it.
