汽车嵌入式系统开发方法、体系架构和流程

Methodology, Architecture and Development Flow of Automotive Embedded Systems

摘要:

介绍了汽车嵌入式系统的内涵，回顾了汽车嵌入式系统的技术发展历史，分析了未来汽车嵌入式系统发展的特点，并得出以下结论：开发一个高效、可靠的汽车嵌入式系统离不开简明精确的开发方法、完善细致的体系架构和详细合理的开发流程。在此基础上，概括了汽车嵌入式系统开发的技术体系，并具体地从基于模型的开发方法、基于AUTOSAR(automotive open system architecture)的体系架构以及基于V模式的开发流程３个方面介绍了该技术体系。这三者分别从对象的描述、对象的层次结构和开发的时间顺序３个不同的方面对嵌入式系统的开发方法做了定义和约束，从而保证了这个开发体系的可靠性和完整性。

Abstract:

The development of the automotive embedded system has been more and more complex. This paper reviews the history of the automotive embedded system, and its principles and future characteristics are also introduced and analyzed. It concludes that to develop a high efficient and reliable automotive embedded system relies on an accurate developing method, a systematic architecture and a reasonable process. A detailed introduction to this methodology including the Model Based Development (MBD), the AUTOSAR architecture and the V mode development process is also given. The MBD defines the description of the object, the AUTOSAR architecture describes the structure of the object, and V mode process guides the sequence of the development steps. With the methodology, the reliability and integrity of the automotive embedded system development could be guaranteed.
