driving automation system¶
hardware and software system that is able to perform part or all of the dynamic driving task on a sustained basis
Clause: 3.7.3.6
Note 1 to entry: A driving automation system includes any system capable of level 1-5 driving automation.
Note 2 to entry: Driving automation levels are defined in ISO/SAE 22736, which is also known as SAE J3016.
Note 3 to entry: Driving automation levels include level 1 driving automation, level 2 driving automation, level 3 ADS, level 4 ADS, and level 5 ADS.
Note 4 to entry: In contrast to this generic term for any level 1-5 system, the specific term for a level 3-5 system is "Automated Driving System (ADS)." Given the similarity between the generic term, "driving automation system," and the level 3-5-specific term, "Automated Driving System," the latter term is intentionally capitalized when spelled out and reduced to its acronym, "ADS", as much as possible, while "driving automation system" should not be.
History note: Introduced in ISO/TS 14812:2022
Specializations of driving automation system¶
| Class | Description |
|---|---|
| ADS | driving automation system that is able to perform the entire dynamic driving task on a sustained basis |
| driver support system | driving automation system that is only able to perform part of the dynamic driving task |
| level 1 driving automation | driver support system that provides either sustained lateral or sustained longitudinal vehicle motion control within a specific operational design domain with the expectation that a conventional driver completes the dynamic driving task |
| level 2 driving automation | driver support system that provides sustained lateral and longitudinal vehicle motion control within a specific operational design domain with the expectation that a conventional driver completes the object and event detection and response |
| level 3 ADS | ADS designed with the expectation that the fallback-ready user is available to intervene |
| level 4 ADS | ADS that is capable of operating within a specific operational design domain and providing its own fallback, without any expectation that a human driver will respond to a request to intervene |
| level 5 ADS | ADS that is capable of unconditional (i.e. not operational design domain-specific) operation and providing its own fallback, without any expectation that a human driver will respond to a request to intervene |
