_202402 车道维护辅助系统的驾驶员 - 车辆接口注意事项

[中文适用范围]： 本文件旨在为根据ISO 11270定义的瞬时干预型LKA系统提供DVI实施指南。LKA系统通过瞬时干预为安全车道保持操作提供驾驶员支持。根据SAE J3016，LKA系统属于SAE Level 0。LKA系统不持续自动化动态驾驶任务(DDT)的任何部分，也不被视为部分或有条件驾驶自动化系统的组成部分。LKA系统的设计意图是解决由于无意车道或道路偏离导致的碰撞场景。驾驶员可以随时覆盖LKA系统的干预。LKA系统不保证防止车道漂移或相关碰撞。道路和驾驶环境(如车道线划分、恶劣天气、道路曲率、路面等)以及车辆因素(如速度、横向加速度、设备状况等)可能影响LKA系统的运行。本文档适用于总重量额定值小于10000磅的轻型车辆(即乘用车和轻型卡车)上的原装LKA系统的DVI参数。本文档不适用于后装LKA系统或摩托车和中重型车辆上的LKA系统。本文档不涉及LKA系统的系统或操作要求，这些要求由ISO 11270规定。车辆的安全操作责任始终由驾驶员承担。 [外文原描述]： The purpose of this document is to provide guidance for the implementation of DVI for momentary intervention-type LKA systems, as defined by ISO 11270. LKA systems provide driver support for safe lane keeping operations via momentary interventions. LKA systems are SAE Level 0, according to SAE J3016. LKA systems do not automate any part of the dynamic driving task (DDT) on a sustained basis and are not classified as an integral component of a partial or conditional driving automation system per SAE J3016. The design intent (i.e., purpose) of an LKA system is to address crash scenarios resulting from inadvertent lane or road departures. Drivers can override an LKA system intervention at any time. LKA systems do not guarantee prevention of lane drifts or related crashes. Road and driving environment (e.g., lane line delineation, inclement weather, road curvature, road surface, etc.) as well as vehicle factors (e.g., speed, lateral acceleration, equipment condition, etc.) may affect the operation of the LKA system. As used in this document, the term “LKA” refers to lateral control driver assistance that automatically intervenes to address a lane departure if the driver either does not signal intent to change lanes (e.g., via turn signal activation) and/or does not initiate corrective steering action to prevent the lane departure. LKA is temporary in nature and distinct from lane centering assistance, which performs sustained steering adjustments to maintain the vehicle’s lateral position within a given lane. This document addresses DVI parameters for original equipment LKA systems on light-duty vehicles (i.e., passenger cars and light trucks) with a Gross Vehicle Weight Rating of less than 10000 pounds. This document does not apply to the installation of aftermarket LKA systems or those on motorcycles or medium- and heavy-duty vehicles. This document does not address system or operational requirements for LKA systems, which are specified by ISO 11270. The responsibility for the safe operation of the vehicle always remains with the driver.
