| Full qualified VSS Path: | Vehicle.ADAS.ActiveAutonomyLevel |
| Description: | Indicates the currently active level of autonomy according to SAE J3016 taxonomy. |
| Comment: | Follows https://www.sae.org/news/2019/01/sae-updates-j3016-automated-driving-graphic taxonomy. For SAE levels 3 and 4 the system is required to alert the driver before it will disengage. Level 4 systems are required to reach a safe state even if a driver does not take over. Only level 5 systems are required to not rely on a driver at all. While level 2 systems require the driver to be monitoring the system at all times, many level 2 systems, often termed “level 2.5” systems, do warn the driver shortly before reaching their operational limits, therefore we also support the DISENGAGING state for SAE_2. |

About VSS
The Vehicle Signal Specification (VSS) is an initiative by COVESA to define a syntax and a catalog for vehicle signals. The source code and releases can be found in the VSS github repository.
