汽车应用蓝牙无线协议

[中文适用范围]： 该 SAE 信息报告定义了用于远程访问车载电子设备安装的典型蓝牙应用的功能。远程访问可以直接使用板载蓝牙模块实现，也可以通过定制设计的网关间接实现，该网关与蓝牙和非蓝牙模块进行通信。可以通过单个主端口@或通过车辆上的多个端口以双向通信@的形式访问车辆@。蓝牙技术还可以与其他类型的板外无线技术结合使用。本报告建议使用已在2.1.1@、2.1.4@、2.1.5@和2.1.6中列出的一个或多个文档中定义的消息策略。这些策略可用于与车辆的一些典型的远程通信。然而，人们认识到可能存在需要独特消息策略或结构的特定应用。本文档描述了各种类型的通信可能需要的五种不同级别的安全措施。建议实施该协议的 EMC 测试要求。本报告并未尝试定义可利用蓝牙协议的所有应用。附录 B.1 节列出了一些用例，作为代表性应用@例如@信用卡交易@车辆诊断@收费站收费@闪存重新编程@等。 [外文原描述]： This SAE Information Report defines the functionality of typical Bluetooth applications used for remotely accessing in-vehicle automotive installations of electronic devices. Remote access may be achieved directly with on-board Bluetooth modules, or indirectly via a custom designed gateway that communicates with Bluetooth and non-Bluetooth modules alike.Access to the vehicle, in the form of two-way communications, may be made via a single master port, or via multiple ports on the vehicle. The Bluetooth technology may also be used in conjunction with other types of off-board wireless technology.This report recommends using a message strategy that is already defined in one or more of the documents listed in 2.1.1 , 2.1.4 , 2.1.5 , and 2.1.6 . Those strategies may be used for some of the typical remote communications with a vehicle. It is recognized, however, that there may be specific applications requiring a unique message strategy or structure.This document depicts five different levels of security measures that may be required for the various types of communication.The EMC test requirements for the implementation of this protocol are recommended.This report makes no attempt to define all of the applications wherein the Bluetooth protocol may be utilized. A number of use cases are listed in Section B.1 of the appendix to serve as representative applications, e.g., credit card transactions, vehicle diagnostics, toll booth collection, flash reprogramming, etc.Cross Reference: CISPR25,IDB-0008-0F,ISO/WD14229-1.6,J1979_201202,J1979_201408,J2178-1,J2178-2,J2178-3,J2178-4,J2178/1_201104,J2178/2_201104,J2178/3_201105,J2178/4_201104,J2190
