仅用于测试和评估目的的替代基本安全信息

[中文适用范围]： 该文件包含了为装备了V2X的主车辆（eHV）或路边设备（RSE）初始推荐，这些设备可以代表未配备V2X的远程车辆（uRV）广播替代基本安全消息（SBSM）。此文档仅用于测试目的，并使用测试PSID（例如0x7f），而不是由SAE J2945/1和SAE J3161/1标准基本安全消息（BSM）传输使用的PSID（0x20）。 基本原则是，无论是在主车辆上还是在RSE上的V2X设备的主机系统，都可以确定检测到的车辆是否启用了V2X，并且如果没有启用，则为其制定和广播描述其状态的消息给其他启用V2X的设备。此文档基于SAE J2945/1和SAE J3161/1中的V2V安全通信要求以及在SAE J2735中支持的消息集详细信息。 该文件的初始版本是一份信息报告，如果实施、测试和模拟的结果可用，可能会更新为推荐实践或标准。性能、数据质量以及相应消息字段的数据填充需要更多的考虑。 [外文原描述]： This document includes the initial recommendations for a V2X-equipped host vehicle (eHV) or Roadside Equipment (RSE) that can broadcast a surrogate basic safety message (SBSM) on behalf of an unequipped remote vehicle (uRV). This document is published for testing only, using a Test PSID (e.g., 0x7f) and not the PSID used by SAE J2945/1 and SAE J3161/1 for standard basic safety message (BSM) transmission (0x20). The basic principle is that the host system of the V2X capable device, whether on a host vehicle or an RSE, can determine whether detected vehicles are V2X enabled or not, and if not, formulate and broadcast messages on their behalf that describe their status to other V2X enabled devices. This document is based extensively on the V2V safety communication requirements in SAE J2945/1 and SAE J3161/1 and the supporting message set details in SAE J2735. The initial version of this document is an information report. If feedback from implementations, testing, and simulation becomes available, this report may be updated to a recommended practice or standard. The performance, data quality, and corresponding population of message data fields need more consideration.
