基于AUTOSAR自适应平台的PREEvision通信建模方法和原理研究

PREEvision Communication Modeling Based on AUTOSAR AP Research on Methods and Principles

文章以SOMEIP服务通信为例,主要介绍如何通过PREEvision工具开发满足AUTOSAR AP标准的通信模型,以流程为导向,从机器部署、网络设计和服务实例3个方面剖析建模方法,以OSI模型为切入点,从物理层到应用层的5层结构角度,配合实际ARXML的表现,研究AUTOSAR AP的实现机制、理念以及PREEvision建模配置当中的原理,并评估建模过程中的重点关注项。

The article takes SOMEIP service communication as an example and mainly introduces how to develop a communication model that meets the AUTOSAR AP standard through the PREEvision tool.It analyzes modeling methods from three aspects:machine deployment,network design,and service instance based on a process-oriented approach.From the perspective of the OSI model as a starting point,the five-layer structure from the physical layer to the application layer is studied,along with the actual representation of ARXML.The implementation mechanism and concept of AUTOSAR AP,as well as the principles in PREEnvision modeling configuration,are studied,and evaluate the key focus items during the modeling process.
