汽车诊断

ECU诊断功能开发是整个ECU系统开发的重要组成部分。在ECU功能描述中就已经定义了ECU所需的诊断功能,以保证ECU在网络系统中能满足诊断需求。用户在ECU开发的同时创建和实现诊断功能。

基于“单源法则”的CANdela诊断数据库文件,使得诊断规范在ECU的整个生命周期中均能保持一致性,这样能够以简单灵活的方式提供数据给不同的诊断测试者。在网络和系统开发框架中,详细的、系统的诊断测试能够高质量的保证诊断功能的实现。

在汽车诊断开发过程中,最主要的任务可以归结为如下方面:

  • 规范:诊断需求规范和描述
  • ECU软件:在ECU中创建和实现诊断功能
  • 诊断功能确认:测试ECU中诊断协议的实现和集成
  • 诊断测试:在ECU和汽车网络开发过程中使用诊断功能

诊断开发和应用领域中的Vector工具

Vector的诊断开发工具CANdela系列支持汽车诊断功能开发的整个流程。下图显示了不同阶段所需要使用的工具。

Optimize the diagnostic development process with CANdelaStudio using a central database
CANdesc (desc = diagnostic embedded software component) is the ECU diagnostic software component in the development process of the CANdela product family.
Indigo is an easy to use diagnostic tester that is largely self-configured and conceals the complexity of the diagnostic protocols.
Using CANdito, you can do diagnostic testing, flash programming and measurement data acquisition with a single tool
ECU development, calibration, diagnostics, measurement data acquisition
KWP2000 and UDS diagnostic communication can be analyzed with the Diagnostic Feature Set. CANoe can be used as diagnostic tester as well as for the simulation of ECU diagnostics.
The DiVa Option extends CANoe for automatic generation/execution of reproducible test cases for the implementation and integration of the diagnostic protocol.
