本文件已被宣布为“稳定”，不再接受货币定期审查。用户负责验证参考资料和持续适用性或技术要求。新技术可能存在。本手册由SAE AS-2委员会的环形实施任务组编制，旨在通过提供标准本身的解释和使用指南来支持AS4075。编制标准的主要目的是提供操作和性能要求的声明，以及在任何实施中实现的功能的明确定义，主要是从互操作性的角度。虽然在AS4075标准范围内已做出努力，以提供HSRB的可读性一般说明，但详细的解释、原理和使用指南与标准的目的以及格式不符。 因此，本手册包含对标准主要章节的逐段解释，以及对应用和实施问题的讨论。

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist.This Handbook has been prepared by the Ring Implementation Task Group of the SAE AS-2 Committee, and is intended to support AS4075 by providing explanation of the standard itself and guidance on its use.The principal objective in the preparation of a standard is to provide a statement of operational and performance requirements, and an unambiguous definition of the functions to be realized in any implementation, primarily from the view point of interoperability. While efforts have been made within the AS4075 standard to provide a readable general description of the HSRB, detailed explanations, rationale and guidance to the use are incompatible with the purpose and, indeed, the format of a standard. Accordingly, this Handbook contains a paragraph-by-paragraph explanation of the main sections of the standard, and a discussion of application and implementation issues.
