无钥匙点火控制设计

[中文适用范围]： 该 SAE 推荐实践为汽车无钥匙点火系统的操作制定了指南，旨在帮助最大限度地减少用户造成的错误。就本建议实践而言，用户引发的错误可能包括： 无法启动和停止车辆推进系统；退出车辆时，自动变速箱处于非驻车档位；在车辆推进系统启用时离开车辆；当车辆推进系统被禁用，但附件或电气系统处于活动状态时离开车辆。为了帮助最大限度地减少这些错误，本推荐做法包含有关统一标签、操作逻辑、车辆点火/控制状态指示以及无钥匙点火系统的物理控制特性的设计建议。本推荐做法适用于永久安装在总车辆总重量 10 000 及以下的乘用车、MPV 和卡车上的无钥匙点火控制装置。它不适用于提供远程控制以从车外启动或停止车辆发动机的远程启动/远程停止系统。 [外文原描述]： This SAE Recommended Practice establishes guidelines for the operation of automotive keyless ignition systems with the goal of helping to minimize user instigated errors.For the purpose of this Recommended Practice, user instigated errors may include:the inability to start and stop the vehicle propulsion system,exiting the vehicle with the automatic transmission in a non-parking gear,exiting the vehicle while the vehicle propulsion system is enabled,exiting the vehicle while the vehicle propulsion system is disabled, but the accessory or electrical systems are active.To help minimize these errors, this Recommended Practice contains design recommendations pertaining to uniform labeling, operating logic, indication of vehicle ignition/control status, and physical control characteristics of keyless ignition systems.This Recommended Practice applies to keyless ignition controls permanently mounted in passenger cars, MPVs, and trucks 10 000 GVWR and under. It does not apply to remote start/remote stop systems that provide remote controls to start or stop a vehicle engine from outside the vehicle.Cross Reference: FMVSS101,FMVSS102,FMVSS114,ISO2575
