本文件规定: -？运行设计领域的要求， -？系统要求， -？最低性能要求，以及 -？性能测试程序 用于在预定路线上运行的低速自动驾驶（LSAD）系统的安全操作。LSAD系统设计为在特定操作设计领域（ODD）内以4级自动化运行（见ISO/SAE PAS？22736）。 本文件适用于自动驾驶系统专用车辆（ADS-DVs），也可用于双模车辆（见ISO/SAE PAS 22736）。本文件未规定由LSAD系统驱动的车辆中存在的传感器技术。

This document specifies: —？requirements for the operational design domain, —？system requirements, —？minimum performance requirements, and —？performance test procedures for the safe operation of low-speed automated driving (LSAD) systems for operation on predefined routes. LSAD systems are designed to operate at Level 4 automation (see ISO/SAE PAS？22736), within specific operational design domains (ODD). This document applies to automated driving system-dedicated vehicles (ADS-DVs) and can also be utilized by dual-mode vehicles (see ISO/SAE PAS 22736). This document does not specify sensor technology present in vehicles driven by LSAD systems.
