一种基于通信矩阵的汽车电子电气系统建模方法

A Method for Automobile Electronic and Electrical System Modeling Based on Communication-Matrix

在汽车电子电气设计制造领域,基于模型的系统工程思想已经开始逐步取代传统基于文档的设计开发流程。面向PR EEv ison使用的EEA分层模型架构,该文设计实现了一种基于通信矩阵的快速建模方案,采用PREEvison的二次开发功能进行总线通信网络和软硬件网络拓扑的自动化建模。该文提出的方法在工程实践中,显著提高了相关车型平台的建模工作效率并为相关设计企业将现有设计文档转化为可复用的数据模型。

In the field of automotive electrical and electronic design and manufacturing,model-based system engineering has begun to gradually replace the traditional document-based design and development process.For the EEA model architecture used by PREEvison,this paper designs and implements a rapid modeling solution based on communication matrix.Use the secondary development function of PREEvison to automatically model the bus communication network and hardware network topology.In engineering practice,the method proposed in this paper greatly improves the modeling efficiency of related vehicle models and transforms existing design documents into reusable data models for related design companies.
