This document describes [motor] vehicle<\/em> driving automation system<\/em>s that perform part or all of the dynamic driving task<\/em> (DDT<\/em>) on a sustained<\/em> basis. It provides a taxonomy with detailed definitions for six levels of driving automation<\/em>, ranging from no driving automation<\/em> (Level 0) to full driving automation<\/em> (Level 5), in the context of [motor] vehicles<\/em> (hereafter also referred to as \u201cvehicle<\/em>\u201d or \u201cvehicles<\/em>\u201d) and their operation<\/em> on roadways:<\/p>\n

Level 0: No Driving Automation<\/p>\n

Level 1: Driver Assistance<\/p>\n

Level 2: Partial Driving Automation<\/p>\n

Level 3: Conditional Driving Automation<\/p>\n

Level 4: High Driving Automation<\/p>\n

Level 5: Full Driving Automation<\/p>\n

These level definitions, along with additional supporting terms and definitions provided herein, can be used to describe the full range of driving automation<\/em> features<\/em> equipped on [motor] vehicles<\/em> in a functionally consistent and coherent manner. \u201cOn-road\u201d refers to publicly accessible roadways (including parking areas and private campuses that permit public access) that collectively serve all road users<\/em>, including cyclists, pedestrians, and users<\/em> of vehicles<\/em> with and without driving automation<\/em> features<\/em>.<\/p>\n

The levels apply to the driving automation<\/em> feature<\/em>(s) that are engaged in any given instance of on-road operation<\/em> of an equipped vehicle<\/em>. As such, although a given vehicle<\/em> may be equipped with a driving automation system<\/em> that is capable of delivering multiple driving automation<\/em> features<\/em> that perform at different levels, the level of driving automation<\/em> exhibited in any given instance is determined by the feature<\/em>(s) that are engaged.<\/p>\n

This document also refers to three primary actors in driving: the (human) user<\/em>, the driving automation system<\/em>, and other vehicle<\/em> systems and components. These other vehicle<\/em> systems and components (or the vehicle<\/em> in general terms) do not include the driving automation system<\/em> in this model, even though as a practical matter a driving automation system<\/em> may actually share hardware and software components with other vehicle<\/em> systems, such as a processing module(s) or operating<\/em> code.<\/p>\n

The levels of driving automation<\/em> are defined by reference to the specific role played by each of the three primary actors in performance of the DDT<\/em> and\/or DDT fallback<\/em>. \u201cRole\u201d in this context refers to the expected role of a given primary actor, based on the design of the driving automation system<\/em> in question and not necessarily to the actual performance of a given primary actor. For example, a driver<\/em> who fails to monitor the roadway during engagement of a Level 1 adaptive cruise control (ACC) system still has the role of driver<\/em>, even while s\/he is neglecting it.<\/p>\n

Active safety systems<\/em>, such as electronic stability control (ESC) and automatic emergency braking (AEB), and certain types of driver<\/em> assistance systems, such as lane keeping assistance (LKA), are excluded from the scope of this driving automation<\/em> taxonomy because they do not perform part or all of the DDT<\/em> on a sustained<\/em> basis, but rather provide momentary intervention during potentially hazardous situations. Due to the momentary nature of the actions of active safety systems<\/em>, their intervention does not change or eliminate the role of the driver<\/em> in performing part or all of the DDT<\/em>, and thus are not considered to be driving automation<\/em>, even though they perform automated functions. In addition, systems that inform, alert, or warn the driver<\/em> about hazards in the driving environment are also outside the scope of this driving automation<\/em> taxonomy, as they neither automate part or all of the DDT<\/em>, nor change the driver<\/em>\u2019s role in performance of the DDT<\/em> (see 8.13).<\/p>\n

It should be noted, however, that crash avoidance features<\/em>, including intervention-type active safety systems<\/em>, may be included in vehicles<\/em> equipped with driving automation system<\/em>s at any level. For automated driving system<\/em> (ADS<\/em>) features<\/em> (i.e., Levels 3 to 5) that perform the complete DDT<\/em>, crash mitigation and avoidance capability is part of ADS<\/em> functionality (see also 8.13).<\/p>\n","protected":false},"excerpt":{"rendered":"
