SAE refines definitions of driving automation levels 10 May 2021 4:51 pm / 0 comments In light of the rapid advancement in autonomous driving technologies and functions, SAE International in collaboration with the International Organisation for Standardisation (ISO) has announced a key update to the most-cited reference for self-driving capabilities: the SAE J3016 Taxonomy and Definitions for Terms Related to Driving Automation Systems for On-Road Motor Vehicles, or the SAE Levels of Driving Automation. The SAE-defined levels are more commonly known as Level 0, for driving with no added assistance, through to Level 5, which is for fully automated driving. The basic framework for the different levels of assistance remains the same, albeit with more detail on the differences of operation between Level 3 and Level 4.
