摘要
针对汽车ECU常规开发方法用于整车系统级分析与建模存在的缺陷与不足,基于汽车开放式系统架构(AUTOSAR)基本理论,首先阐述了AUTOSAR规范的层次化、模块化系统架构及层间接口,进而建立一个由架构定义与ECU配置2个阶段构成的AUTOSAR实现过程,最后结合市场典型的AUTOSAR工具,给出一个系统的汽车ECU软件开发解决方法。研究结果表明:给出的方法简洁高效,能够保证整车电子控制软件系统的可扩展性、模块可重用性与可靠性,这对低成本高可靠性的汽车ECU系统开发具有重要意义。
Aimed at the shortcomings of traditional automobile ECU development methods for the whole vehicle system-level analysis and modeling,and based on the basic theories of automobile open system architecture（AUTOSAR）,the hierarchical modular system architecture and the inter-layer interfaces for AUTOSAR were explained at first,and then,an implementation process consisting of two phases,i.e.,architecture definition phase and ECU configuration phase,was established.And finally,combined with typical AUTOSAR tools on market,a systematical resolution for automobile ECU software development was proposed.The results show that the proposed resolution is simple and efficient,which can ensure the expansibility,modular reuse and reliability of the electric control software system of the whole vehicle.This study is significance for high reliability and low cost automobile ECU system development.6 figs,14 refs.
