通过执行一组有限的横向和/或纵向的车辆运动控制动作来满足特定的、狭义的用例（如，停车机动），以支持驾驶员执行其余的DDT（动态驾驶任务），并对L1或L2级自动驾驶功能的操作进行监管（即L1或L2的驾驶员支持功能）；
or
2. Executes a limited set of lateral and longitudinal vehicle motion control actions, as well as associated object and event detection and response (OEDR) and all other elements of the complete DDT in order to fulfil a specific, narrowly defined use case without human supervision (Level 3 or 4 ADS features).
要么，在没有人类监管的情况下，执行一组有限的横向和纵向的车辆运动控制动作，以及相关的OEDR（目标和事件探测与响应）和其余所有的DDT ，以完成一项特定的、狭义的用例（L3或L4级自动驾驶功能）。
EXAMPLE 1: A Level 1 parking assistance feature automatically performs the lateral vehicle motion control actions necessary to parallel park a vehicle, while the driver performs the longitudinal vehicle motion control actions and supervises the feature.
EXAMPLE 2: A Level 2 parking assistance feature automatically performs the lateral and longitudinal vehicle motion control actions necessary to parallel park a vehicle under the supervision of the driver.
EXAMPLE 3: A Level 3 highway overtaking assistance feature automatically performs the lateral and longitudinal vehicle motion control actions, as well as associated OEDR, necessary to pass a slower-moving vehicle on a multi-lane highway when activated by the driver or fallback-ready user.
3.7.2 SUB-TRIP FEATURE （sub-trip 功能）
A driving automation system feature equipped on a conventional vehicle that requires a human driver to perform the complete DDT for at least part of every trip.
一种搭载在传统车辆上的驾驶自动化系统功能，要求人类驾驶员在每次行驶过程中的至少部分时间内，实现全部的DDT操作。
NOTE: Sub-trip features require a human driver to operate the vehicle between the point-of-origin and the boundary of the feature’s ODD and/or after leaving the feature’s ODD until the destination is reached (i.e., trip completion).
EXAMPLE 1: A Level 1 adaptive cruise control (ACC) feature performs longitudinal vehicle motion control functions to support the driver in maintaining consistent headway to a lead vehicle in its lane when travelling at higher speeds.
EXAMPLE 2: A Level 2 highway feature performs lateral and longitudinal vehicle motion control functions to support the driver in maintaining position within its lane of travel, as well as consistent headway to a lead vehicle in its lane when travelling at higher speeds.
EXAMPLE 3: A Level 3 traffic jam feature performs the complete DDT on a fully access-controlled freeway in dense traffic, but requires a human driver to operate the vehicle upon ODD exit (e.g., when traffic clears, as well as before entering the congested freeway, and again upon exiting it).
