"SAE J3016 Driving Automation Classification" updated version released

On April 30, 2021, SAE International announced an important update. With the rapid development of driving automation, the industry-focused and widely cited "SAE J3016™ Recommended Practice: Classification of Terms Related to Road Motor Vehicle Driving Automation Systems" The updated version developed in cooperation with ISO-International Organization for Standardization has been officially released (commonly known as the "SAE Driving Automation Classification"). SAE J3016 provides classifications with supporting terms and definitions for six levels of driving automation. The SAE driving automation classification ranges from L0 level no driving automation to L5 level full driving automation (for motor vehicles driving on the road).

The updated version of "SAE Driving Automation Classification" has been updated and improved from the previous version, adding some new terms, substantially improving and clarifying misunderstood concepts, and reorganizing some definitions into more logical groupings. Notable changes in this version of the SAE Driving Automation Rating include:

• Further clarify the differences between SAE L3 and SAE L4, including: the role of backup users, the possibility of automatic fallback at SAE L3, and the possibility of alerting users in the vehicle at SAE L4.

• Terms and definitions for the two different remote support functions: Remote Assistance and Remote Driving, and the users who perform these functions: Remote Assistant and Remote Driver.

• SAE L1 and L2 driving automation systems are named "Driver Support Systems", which corresponds to the term "Automated Driving Systems" used by SAE L3-L5 levels.

• Explain how the classification of continuous driving automation fits into the broader context of driver assistance and active safety features.

• The reason why warning and momentary driving intervention systems are not included in the classification of driving automation levels.

• The definitions of vehicle types are grouped: Conventional Vehicle, Dual-mode Vehicle and ADS-dedicated Vehicle.

• Define and clarify the concept of fault mitigation strategies.

Updated version in April 2021

The SAE J3016 Technical Standards Committee, in collaboration with ISO/TC 204 Intelligent Transportation Systems, formed a joint working group with representatives from nine countries to carefully address common issues in earlier versions of the Recommended Practice. The updated version of SAE J3016, which incorporates ISO’s international expert recommendations, will be more applicable to the global mobility community.
