SAE J3045_201808为GVW大于4546 kg（10000磅）的公路卡车和公共汽车中使用的车道偏离警告系统制定了统一的机动车辆试验程序和最低性能要求。本文件不包括功能相似但范围和复杂性不同的系统，包括车道保持/车道辅助和合并辅助。本文件不适用于拖车、推车等。本文件不打算排除任何特定的系统或传感器技术。该规范将测试LDWS（e。 g、 、检测车道存在的能力和检测非预期车道偏离的能力）、指示LDWS接通的能力、指示LDWS断开的能力，以及确定LDWS通知人机界面（HMI）或车辆控制系统检测到车道偏离事件的点。此外，该规范还确定了系统是否以最低可接受水平运行。此处未提及HMI，但SAE标准J2808中考虑了HMI。

SAE J3045_201808 establishes a uniform, powered vehicle test procedure and minimum performance requirement for lane departure warning systems used in highway trucks and buses greater than 4546 kg (10000 pounds) GVW. Systems similar in function but different in scope and complexity, including Lane Keeping/Lane Assist and Merge Assist, are not included in this document. This document does not apply to trailers, dollies, etc. This document does not intend to exclude any particular system or sensor technology.The specification will test the functionality of the LDWS (e.g., ability to detect lane presence, and ability to detect an unintended lane departure), its ability to indicate LDWS engagement, its ability to indicate LDWS disengagement, and determine the point at which the LDWS notifies the Human Machine Interface (HMI) or vehicle control system that a lane departure event is detected. Moreover, the specification determines whether a system performs at a minimally acceptable level. The HMI is not addressed herein but is considered in SAE Standard J2808.
