本文件中的术语和定义描述了SAE J3016中定义的ADS内执行的功能。在可能的情况下，我们试图捕获自动驾驶开发社区中已经使用的语言。在需要的地方，我们增加了新的术语和定义，包括澄清注释以避免歧义。SAE J3131主要涉及4级和5级广告功能。

The terms and definitions in this document describe the functions performed within an ADS, as defined in SAE J3016. Where possible we have attempted to capture the language that is already in use within the automated driving development community. Where needed, we have added new terms and definitions, including clarifying notes to avoid ambiguity. SAE J3131 deals primarily with Level 4 and Level 5 ADS features.
