修改增删部分
1、章节3.21 OPERATIONAL DESIGN DOMAIN (ODD) ，相比原来增加了NOTE 1、EXAMPLE 1 和 EXAMPLE 5 。
NOTE 1: While Level 3 and 4 ADS features/vehicles are designed to operate exclusively within their respective ODDs, some ODD conditions are subject to rapid change during on-road operation (e.g., inclement weather, obscured lane lines). Such transient changes in the operating environment do not necessarily represent an “ODD exit,” as the ADS determines when such a change in conditions requires fallback performance (whether by the fallback- ready user or ADS).
虽然L3和L4级ADS功能/车辆的设计只适用于在各自的ODDs范围内运行，但在道路运行过程中，一些ODD情况会迅速变化（例如，恶劣的天气、模糊的车道线）。操作环境中的这种瞬变变化不一定代表“退出ODD” ，因为ADS决定了在这些变化中何时才需要执行fallback（无论是由预备接管用户执行，还是由ADS执行）。
EXAMPLE 1: A Level 1 ACC driver support feature is designed to provide longitudinal vehicle motion control support to the driver on fully access-controlled freeways under fair weather conditions.
L1级ACC（自适应巡航技术）驾驶员支持功能，设计用于在晴朗的天气条件下，为驾驶员在受控通道高速公路上提供纵向的车辆运动控制的支持。
EXAMPLE 5: A level 3 ADS highway feature with an ODD requirement of clearly visible lane lines encounters a short stretch of roadway with obscured lane lines. The ADS feature is able to compensate for brief periods of faded or missing lane markings through other means (e.g., sensor fusion, digital map, lead vehicle following) and continues to operate the vehicle for a brief period before the lane lines again become clearly visible. A short while later, the lane lines again become obscured and remain so for longer duration, causing the ADS feature to issue a request to intervene to the fallback-ready user.
当一项ODD要求有清晰可见的车道线的L3级ADS高速公路功能，遇上了一小段车道线模糊的道路， ADS功能能够通过其他手段（如传感器融合、数字地图、前车跟踪）对短时间内褪色或丢失的车道标记进行补偿，并在车道线再次清晰可见之前继续操作车辆一小段时间。之后，如果车道线再次变得模糊，并持续较长时间的话，就会导致ADS功能向预备接管用户发出干预请求。
