本SAE推荐实践定义了系统和部件功能、测量指标、用于评估轮胎压力系统功能和性能的测试方法，以及已知操作环境中的推荐维护实践。 本文件适用于车辆额定总重（GVWR）超过7257 kg（16 000 US lb）的单单元动力车辆的所有车轴和所有车轮组合，以及最多三（3）个牵引单元的多单元车辆组合，这些车辆组合使用SAE J560连接器进行电源和/或通信，或等效的后续连接器技术，或使用合适容量的无线解决方案。 所包括的单底盘车辆的示例包括多用途车和送货车、拖车、货架卡车、公共汽车、休闲车、燃料车、垃圾车、自卸卡车、水泥车和拖拉机。使用SAE J560或后续连接器的组合车辆的示例包括封闭式厢式拖车、液体罐车、平台拖车、记录器拖车、汽车运输拖车及其相关联和兼容的牵引动力装置。对于包括两个或更多拖车的组合车辆，也包括推车。包括的车辆可以是新制造的车辆或现有的车辆。 建议这些系统解决由OEM和/或特种车辆制造商最初安装在车辆上的所有在役轮胎，包括车辆安装的备件，对于售后市场（包括替换或备件），建议（但可选）解决在车辆初始销售或使用日期后安装的所有轮胎/轮辋组合。 本文件将重点介绍监测型轮胎压力系统。注意:本版文档中未涉及以下系统。管理系统类型以及维护和管理类型的更成熟/复杂版本，包括两者的车载报告/存储/检索数据功能，将在本文件系列的未来变更/补充中单独讨论。 1] 轮胎压力维护系统-（通常称为阿季斯-自动轮胎充气系统）直接或间接感测压力并将轮胎压力保持在最小指定阈值以上并通知驾驶员系统活动的系统。 2] 轮胎压力管理（调节）系统（通常称为CTIS-中央轮胎充气系统）-检测压力以及其他相关参数（即车辆负载和速度、轮胎温度等）的系统。)直接或间接，并将压力调节或维持在适合条件的水平，并通知驾驶员系统的活动。

This SAE recommended practice defines the system and component functions, measurement metrics, testing methodologies for evaluating the functionality and performance of tire pressure systems, and recommended maintenance practices within the known operating environments. This document is applicable to all axle and all wheel combinations for single unit powered vehicles exceeding 7257 kg (16 000 US lb) gross vehicle weight rating (GVWR), and multi-unit vehicle combinations, up to three (3) towed units, which use an SAE J560 connector for power and/or communication, or equivalent successor connector technology, or which use a suitable capacity wireless solution. Examples of included single chassis vehicles would be – utility and delivery vans, tow trucks, rack trucks, buses, recreational vehicles, fuel trucks, trash trucks, dump trucks, cement trucks, and tractors. Examples of combination vehicles using an SAE J560 or successor connector would be – enclosed van trailers, liquid tanker, platform trailer, logger trailers, auto transit trailers, and their associated and compatible towing power units. For combination vehicles including two or more trailers, the dollies are also included. The included vehicles can be newly manufactured vehicles or existing vehicles. These systems are recommended to address all tires in service as originally installed on a vehicle by the OEM and/or specialty vehicle manufacturer, including the vehicle mounted spares, and, for the aftermarket (including replacement or spare parts) are recommended (but optional) to address all tire/rim combinations installed after initial vehicle sale or in-use dates. This document will focus on tire pressure systems of the monitoring type. NOTE: The following systems are not being addressed in this edition of the document. The management system types and more mature/complex versions of maintenance and management types, to include on-board reporting/storage/retrieval data capabilities for both, will be addressed separately by future changes/additions to this document series. 1] Tire Pressure Maintenance Systems – (typically known as ATIS – Automatic Tire Inflation Systems) systems which sense pressure directly or indirectly and maintain tire pressure above a minimum specified threshold, and inform the driver of the system’s activity. 2] Tire Pressure Management (adjustment) Systems (typically known as CTIS – Central Tire Inflation Systems) – systems which sense pressure, plus other pertinent parameters (i.e., vehicle load and speed, tire temperature, etc.) directly or indirectly, and adjust or sustain the pressure at a the level appropriate for the conditions, and inform the driver of the system’s activity.
