基于AUTOSAR规范的汽车ECU软件开发方法

Software development method based on AUTOSAR for automobile ECUs

针对汽车ECU常规开发方法用于整车系统级分析与建模所存在的缺陷与不足,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配置两个阶段构成的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E-CU软件开发解决方法。研究结果表明,所提方法简洁高效的,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,这对于低成本高可靠性的汽车ECU系统开发具有重要指导意义。

Aiming 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 are expatiated on at first, and then, an implementation process consisted of two phases, i.e., architecture definition phase and ECU configuration phase, are established. And finally, considering with typical AUTOSAR tools on market, one systematical resolution for automobile ECU software development is proposed. The results show that the proposed resolution is simple and efficient, which can ensure the expansibility, modular-re-use and reliability for the electric control software system of the whole vehicle; it has important significance for high reliability and low cost automobile ECU system developments. 6 figs, 15 refs.
