本文件包含PAL的基本控制策略、最低功能要求、基本驱动接口元素、故障反应最低要求和性能测试程序。 伙伴在驾驶员的引导和监督下执行部分或全部换道任务。PAL旨在在具有可见车道标记的道路上运行，禁止非机动车和行人（例如，门禁公路），并在车辆朝同一方向行驶的情况下将车道转换为车道。带有临时或不规则车道标记的路段（如道路施工区）上的支撑不在本文件范围内。 本文件不描述基于纵向控制系统组合的功能，如ISO 22839（FVCMS）或ISO 15622（ACC）中标准化的纵向控制系统。 驾驶员始终对此系统负责，驾驶员的决策和操作始终处于优先地位。 PALS适用于轻型和重型车辆（重型卡车和公共汽车）。 本文件不涉及检测传感器的任何功能或性能要求，也不涉及合作解决方案的任何通信链路。

This document contains the basic control strategy, minimum functionality requirements, basic driver interface elements, minimum requirements for reaction to failure, and performance test procedures for PALS. PALS perform part or all of lane change tasks under the driver's initiation and supervision. PALS are intended to function on roads with visible lane markings, where non-motorized vehicles and pedestrians are prohibited (e.g. access controlled highway), and to perform a lane change into a lane with traffic moving in the same direction. Support on sections of roadway with temporary or irregular lane markings (such as roadwork zones) is not within the scope of this document. This document does not describe functionalities based on combinations with longitudinal control systems such as those standardized in ISO 22839 (FVCMS) or ISO 15622 (ACC). The driver always assumes responsibility for this system and the driver's decisions and operations take priority at all times. Use of PALS is intended for light-duty and heavy-duty vehicles (heavy trucks and buses). This document does not address any functional or performance requirements for detection sensors, nor any communication links for co-operative solutions.
