本SAE推荐实施规程定义了用于评估地面车辆轮胎气压维护（ATIS）系统（自动将充气压力恢复至规定水平的系统）功能和性能的系统和部件功能、测量指标和测试方法，以及在已知操作环境中为这些系统推荐的维护实践。建议使用这些系统来处理OEM和/或专业车辆制造商最初安装在车辆上的所有可维修轮胎，对于售后市场（包括更换件或备件），建议（但可选）来处理车辆首次销售或使用日期后安装的所有轮胎/轮辋组合。本文件适用于以下车型的所有车轴和车轮组合- 额定车辆总重（GVWR）超过7257 kg（16 000 lb）的单单元动力车辆，以及使用SAE J560连接器进行动力和/或通信或同等后续连接器技术的多单元车辆组合，最多三个牵引单元。对于包括两个或两个以上拖车的组合车辆，还包括小车轴。包括的车辆可以是新制造的车辆或现有车辆，配备了空气或液压制动系统。这类车辆通常被称为双轮胎均衡器。当采用ATIS系统时，不建议使用双轮胎均衡器系统，因为它们与维护系统的用途背道而驰。注:本版主题文件中未涉及以下系统。 管理系统类型和更成熟/复杂版本的维护和管理类型，包括车载报告/存储/检索数据/控制功能，将通过本系列文件的未来更改/添加单独解决。胎压监测系统——这些系统已在SAE J2848-1中进行了说明。

This SAE Recommended Practice defines the system and component functions, measurement metrics, and testing methodologies for evaluating the functionality and performance of ground vehicle tire pressure maintenance (ATIS) systems (systems which automatically restore the inflation pressure to its specified level), and recommended maintenance practices for these systems within the known operating environments.These systems are recommended to address all serviceable tires as originally installed on a vehicle by the OEM and/or specialty vehicle manufacturer, 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 is applicable to all axle and all wheel combinations for the following vehicle types - single unit powered vehicles exceeding 7257 kg (16 000 lb) gross vehicle weight rating (GVWR), and multi-unit vehicle combinations, up to three towed units, which use an SAE J560 connector for power and/or communication, or equivalent successor connector technology. For combination vehicles including two or more trailers, the dolly axles are also included. The included vehicles can be newly manufactured vehicles or existing vehicles, fitted with air or hydraulic braking systems.SPECIAL NOTE: Equipment known as ‘dual tire equalizers’ are commonly used with this category of vehicles. When employing an ATIS system, dual tire equalizers systems are not recommended as they run counter to the purpose of the maintenance system.NOTE: The following systems are not being addressed in this edition of the subject document.The management system types and more mature/complex versions of maintenance and management types, to include on-board reporting/storage/retrieval data/control capabilities, will be addressed separately by future changes/additions to this document series.Tire pressure monitoring systems - These systems have been addressed under SAE J2848-1.
