卡车和公交车道驶离警告系统测试流程及最低性能要求

[中文适用范围]： 本 SAE 建议规范为总车重 (GVW) 超过 4546 千克 (10000 磅) 的公路卡车和公共汽车中使用的车道偏离警告系统建立了统一的动力车辆测试程序和最低性能要求。本文档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。本文档不适用于拖车、手推车等。本文档无意排除任何特定的系统或传感器技术。本文档将测试车道偏离警告系统 (LDWS) 的功能（例如，检测车道存在的能力和检测意外车道偏离的能力）、指示 LDWS 接合的能力、指示 LDWS 脱离的能力以及确定 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的能力。此外，本文档确定系统是否在最低可接受水平上运行。本文未涉及 HMI，但在 SAE J2808 中进行了考虑。 [外文原描述]： This SAE Recommended Practice 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) gross vehicle weight (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. This document will test the functionality of the lane departure warning system (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 its ability to 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, this document determines whether a system performs at a minimally acceptable level. The HMI is not addressed herein but is considered in SAE J2808.
