ADS-dedicated vehicle

ADS-equipped vehicle designed for only driverless operation for complete trips

ADS-equipped vehicle designed for only driverless operation for complete trips

ADS-equipped vehicle; automated vehicle (AV)

DEPRECATED: autonomous vehicle - vehicle integrated with an ADS
NOTE 1 to entry: The terms “automated vehicle” and “AV” are often used in a colloquial form. However, these terms can be used to mean either an “ADS-equipped vehicle” or a “vehicle with an engaged ADS”. The term “ADS- equipped vehicle” is preferred since it is more precise and descriptive in its meaning.

DEPRECATED: autonomous vehicle - vehicle integrated with an ADS
NOTE 1 to entry: The terms “automated vehicle” and “AV” are often used in a colloquial form. However, these terms can be used to mean either an “ADS-equipped vehicle” or a “vehicle with an engaged ADS”. The term “ADS- equipped vehicle” is preferred since it is more precise and descriptive in its meaning.
NOTE 2 to entry: The term “autonomous vehicle” is also often used in a colloquial form and is even less well defined. The term is particularly problematic because the word “autonomous” has been used for a long time in the robotics and artificial intelligence research communities to signify systems that have the ability and authority to make decisions independently and self-sufficiently. Due to its imprecise and overly broad meaning, use of the term “autonomous vehicle” is discouraged.
NOTE 3 to entry: This term can be, and when possible should be, refined by identifying the level of automation. For example, the terms “level 5 ADS-equipped vehicle” and “level 5 automated vehicle” should be interpreted as “ADS-equipped vehicle where the ADS is a level 5 ADS”.
NOTE 4 to entry: This term only describes the capabilities of the vehicle, not its operational state. In other words, the term applies as long as the ADS is connected to the vehicle, whether the DDT is actively engaged or not.

ADAS

advanced driver assistance systems

automated driving system (ADS)

driving automation system that is able to perform the entire DDT on a sustained basis
NOTE 1 to entry: The abbreviated form (“ADS”) is the most preferred form and the alternative form (“Automated Driving System”) uses initial capitals to avoid confusion with the more general “driving automation system”.

conditional driving automation; level 3 Automated Driving System (Level 3 ADS)

ADS designed with the expectation that the fallback-ready user is available to intervene
NOTE 1 to entry: Level 3 ADSs are restricted to operating within a specific ODD.
NOTE 2 to entry: Other driving automation levels include “level 1 driving automation”, “level 2 driving automation”, “level 4 ADS”, and “level 5 ADS”.

coverage zone

the coverage zone is defined as the entire area to be monitored by a LCDAS; in other words, a target vehicle located within the coverage zone will be detected by the system
NOTE 1 to entry: A system’s coverage zone will consist of a specific subset of the following zones: left adjacent zone, right adjacent zone, left rear zone, and right rear zone.
