The levels of driving automation, the industry's go-to framework, were updated this week to clarify differences between Level 3 and Level 4, part of an effort to better define and group the capabilities of autonomous technologies that are on the road and under development.
The six levels, established by SAE International in 2014, describe the capabilities of driver-assistance and autonomous driving systems. The levels range from 0 — no driving automation — to 5 — full automation.
SAE and the International Organization for Standardization have clarified Levels 3 and 4 under the J3016 automation standards.
The update also provides an explanation for "how classifications of sustained driving automation fit into the broader context of driver assistance and active safety features," according to SAE.
The update clarifies the role of the fallback-ready user, the possibility of some automated fallback at Level 3, as well as the possibility of some alerts …
