第十章  AUTOSAR OS;主要内容;第一节概述;1 什么是OSEK/VDX;The French car manufacturers PSA and Renault joined OSEK in 1994 introducing their VDX-approach (Vehicle Distributed eXecutive) which is a similar project within the French automotive industry. //1994年，法国PSA和Renault加入OSEK：VDX方法，法国汽车工业项目 At the first workshop on October 1995 the OSEK/VDX group presented the results of the harmonised specification between OSEK and VDX. //1995年10月 After the 2nd international OSEK/VDX Workshop in October 1997 the 2nd versions of the specifications were published. ;The open architecture introduced by OSEK/VDX comprises the three areas: //OSEK/VDX开放体系结构的三个组成部分 Communication (data exchange within and between control units) Operating System (real-time execution of ECU software and base for the other OSEK/VDX modules) Network Management (Configuration determination and monitoring);Motivation high, recurring expenses in the development and variant management of non-application related aspects of control unit software //控制单元软件的高开发成本 incompatibility of control units made by different manufactures due to different interfaces and protocols //不同制造厂不同接口和协议带来的控制单元的不兼容 Goal Support of the portability and reusability of the application software by: //应用软件的可移植性、可用性 specification of interfaces which are abstract and as application-independent as possible //应用无关的接口 specification of an user interface independent of hardware and network //硬件和网络无关的接口 efficient design of architecture: The functionalities shall be configurable and scalable, to enable optimal adjustment of the architecture to the application in question //体系结构：可配置、可扩展性 verification of functionality and implementation of prototypes in selected pilot projects ;Structure The Steering Committee is responsible for the overall project organization and co-ordination (e.g. assignment of working group leaders), for granting of licenses to other companies, and for the external representation of OSEK/VDX (e.g. publications).
