标准摘要
[中文适用范围]: 本文件定义了通过单边半字节传输 (SENT) 编码报告传感器信息的数字脉冲方案实施的标准化级别。该标准将使 ECU 和工具制造商能够通过对基本设计进行最少的修改来满足多个最终用户的需求。该标准将使汽车原始设备制造商 (OEM) 受益,因为基础设计的行业产量更高,从而降低 ECU 成本。本文档中规定的要求提供了所有兼容 ECU 和介质设计时应达到的最低标准性能水平。这确保了所有连接设备之间的数据通信,无论供应商如何。目标受众包括@但不限于@ECU供应商@传感器供应商@组件发布工程师和车辆系统工程师。概述 单边半字节传输编码方案 (SENT) 适用于需要将高分辨率传感器数据从传感器传输到发动机控制单元 (ECU) 的应用。它旨在替代 10 位 A/D 和 PWM 的较低分辨率方法,并作为 CAN 或 LIN 的更简单的低成本替代方案。该实现假设传感器是包含微处理器或专用逻辑器件 (ASIC) 来创建信号的智能传感器。 SENT 是从传感器/发送设备到控制器接收设备的单向通信方案,不包括来自控制器接收设备的协调信号。传感器信号以一系列脉冲的形式传输,并以下降沿时间测量数据。对于本说明书的子文档中描述的特定传感器应用,实现的细节可能会有所不同。 [外文原描述]: This document defines a level of standardization in the implementation of the digital pulse scheme for reporting sensor information via Single Edge Nibble Transmission (SENT) encoding. This standard will allow ECU and tool manufacturers to satisfy the needs of multiple end users with minimum modifications to the basic design. This standard will benefit vehicle Original Equipment Manufacturers (OEMs) by achieving lower ECU costs due to higher industry volumes of the basic design.Requirements stated in this document provide a minimum standard level of performance to which all compatible ECUs and media shall be designed. This assures data communication among all connected devices regardless of supplier.This document is a communication interface specification and no to be treated as product specification.The intended audience includes, but is not limited to, ECU suppliers, sensor suppliers, component release engineers and vehicle system engineers.Cross Reference:
