SAE Level | Name | Narrative definition | Execution of steering and acceleration/ deceleration | Monitoring of driving environment | Fallback performance of dynamic driving task | System capability (driving modes) |
---|
Human driver monitors the driving environment |
0 | No Automation | The full-time performance by the human driver of all aspects of the dynamic driving task, even when “enhanced by warning or intervention systems” | Human driver | Human driver | Human driver | n/a |
1 | Driver Assistance | The driving mode-specific execution by a driver assistance system of “either steering or acceleration/deceleration” | using information about the driving environment and with the expectation that the human driver performs all remaining aspects of the dynamic driving task | Human driver and system | Some driving modes |
2 | Partial Automation | The driving mode-specific execution by one or more driver assistance systems of both steering and acceleration/deceleration | System |
Automated driving system monitors the driving environment |
3 | Conditional Automation | The driving mode-specific performance by an automated driving system of all aspects of the dynamic driving task | with the expectation that the human driver will respond appropriately to a request to intervene | System | System | Human driver | Some driving modes |
4 | High Automation | even if a human driver does not respond appropriately to a request to intervene the car can pull over safely by guiding system | System | Many driving modes |
5 | Full Automation | under all roadway and environmental conditions that can be managed by a human driver | All driving modes |
