Diagnostic Communication with Road-Vehicles and Non-Road Mobile Machinery

Diagnostic Communication with Road-Vehicles and Non-Road Mobile Machinery examines the communication between a diagnostic tester and E/E systems of road-vehicles and non-road mobile machinery such as agricultural machines and construction equipment. The title also contains the description of E/E systems (control units and in-vehicle networks), the communication protocols (e.g. OBD, J1939 and UDS on CAN / IP), and a glimpse into the near future covering remote, cloud-based diagnostics and cybersecurity threats.

汽车电子著作: Road Vehicles – Diagnostic Communication

技术和应用

Softing,为汽车诊断技术、总线通讯和测试技术提供关键解决方案,并在此领域领跑全球,Softing公司出版了一本新书,命名为《Road vehicles - Diagnostic communication》。

当前我们能从汽车中获得的便捷舒适的体验是依靠车载电子控制单元来提供,这些电控单元通过汽车总线系统相互连接在一起并交换数据(在线通讯)。

离线通信技术支持外部测试设备(OBD扫描工具,HIL硬件在环测试系统,刷新站,车间测试仪等)和汽车电控单元之间的诊断通信。

本书介绍了基本的通信原则,协议及各种总线系统,如CAN,LIN,FlexRay和MOST。

UDS诊断协议的详细说明(Unified Diagnostic Services,统一诊断服务)放在基于ASAM MCD系统的外部测试工具结构之后,同时还详细介绍了ISO规范MVCI(Modular Vehicle Communication Interface,模块化车辆通信接口)和ODX数据格式(Open Diagnostic Data Exchange,开放的诊断数据交换)。

为清楚起见,我们选取车辆生命周期的不同阶段的几个实例作为工程示例,包括协议的开发,硬件在环系统,flash程序下载到基于PDA的OBD的扫描工具和车间的测试仪。
