SAE-2020-J3101 美国汽车协会2016年发布的关于车辆硬件安全方面的标准J3101。Automotive computer systems are required to establish trustworthiness through device identity, sealing, attestation, data integrity, and availability. These systems must be res小 ent to a wide range of attacks that cannot be thwarted through software-only security mechanisms. A hardware root of trust and the hardware-based security primitives are fundamentally necessary to satisfy demands of connected and highly or fully automated vehicles. This document provides a comprehensive view of security mechanisms supported in hardware for automotive use cases, along with best practices for using such mechanisms. The goal of this document is to provide a common reference that facilitates communication among engineers across different parts of the automotive supply chain relevant to hardware-enabled security features. Silicon vendors will find this document useful in understanding the hardware security foundations and their corresponding use cases and applications that they should support to address vehicle security needs. This document should also bring more order into the diverse nature of hardware security features, so products are developed with the end use case in mind and with the right level of security. ECU suppliers and system integrators will benefit from the different security requirements and use cases outlined here as they assess the threats that affect their systems and the right hardware systems needed to address them.

SAE J1939 中英文集合（包括21、31、71、73、74、75等相关协议内容）

本文件规定了常见 EV/PHEV 和供应设备汽车传导式充电方法，包括汽车插孔和对接连接器的操作要 求和功能与尺寸要求。美国标准

SAE J1979里面有OBD测试标准。如果写OBD测试程序，参考它就可以了。

本SAE J1979-2007文档详细说明了诊断服务和功能性寻址请求/响应信息，该信息要求受机动车辆和外部测试设备支持，以达到诊断的目的，得到机动车辆与排放有关的数据。包含ISO15765-4诊断服务定义、ISO9141-2，ISO 14230-4和SAE J1850诊断服务定义、（标准的）支持的参数识别符(PID）／车载诊断监视识别符（OBDMID）/测试识别符（TID）/信息类型（INFOTYPE）定义、（标准的）服务$01和$02的PID（参数识别符）换算与定义、（标准的）TIDS（测试 ID）换算比例描述、（标准的）服务$06的OBDMIDS（车载诊断监控器ID）定义、（标准的）服务$06的单位与换算比定义、（标准的）服务$08测试ID（TID）的换算与定义、（标准的）服务$09的信息类型（INFOTYPE）换算与定义等详细解释说明。

本系列 SAE 推荐操作规程是由卡车及客车电子电气委员会所属的卡车及客车控制及通信小组委员会制定的。该小组委员会的目标是针对电控单元的需求、设计和使用，提交消息报告、制定推荐操作规程。这些电控单元在汽车部件之间传递着电子信号和控制信息。本规程的使用不限于卡车和客车应用，其对于其他的应用也可以提供直接的支持，正如已在建筑及农业设备和固定式的动力系统。

Time-Triggered Ethernet functionality described in the SAE AS6802 standard is a Layer 2 Quality-of-Service (QoS) enhancement for Ethernet networks. It provides the capability for deterministic, synchronous, and congestion-free communication, unaffected by any asynchronous Ethernet traffic load.

J1939基于德国Bosch公司（Robert Bosch GmbH）开发的控制器局域网络（CAN：Controller Area Network），可达到250Kbps的通讯速率。它描述了重型车辆现场总线的一种网络应用，包括CAN网络物理层定义、数据链路层定义、应用层定义、网络层定义、故障诊断和网络管理。在SAE J1939协议中，不仅仅指定了传输类型、报文结构及其分段、流量检查等，而且报文内容本身也做了精确的定义。J1939是在商用车辆、舰船、轨道机车、农业机械和大型发动机中应用最广泛的应用层协议。
