Preface

Do you know the following questions ？

  • When the system fails , How should the system react ？

  • How to realize when a fault occurs , The system makes corresponding predictable behavior ？

  • We often talk about system degradation and FiM What is the relationship ？

  • FiM How does it interact with other basic software modules ？

  • How to achieve Event And FiD Of Mapping Relationship ？

  • ……

This article , Let's explore and answer these questions together . For your understanding , The following is the outline of the theme of this article ：

FiM Main functions of the module

Through to AUTOSAR Analysis of standard documents , Summarized below ：

  • FiM The module provides a function degradation strategy based on suppression scenario , At the same time, the suppression scenario can be configured ;

  • Through specific Function Identifier To achieve the corresponding suppression scenario ;

  • Suppression scenarios can be based on Dem Modular Event stay FiM The module completes the mapping according to the degradation requirements ;

  • FiM The module is BSW as well as SW-C The suppression scenario of each module provides an effective means of degradation ;

In short , When SW-C perhaps BSW When the layer fails , It will break down Event Report to DEM modular ,DEM The module will notify... Through some relationship FiM modular ,
