越来越多的基于软件的应用程序正在开发和部署在现代车辆中。因此，系统设计的可扩展性已成为一个重要的问题，以适应更多的未来应用程序和现有的更新，一方面，减少重新设计，测试和验证的努力和成本。在本文中，我们讨论了可扩展性驱动的设计在汽车E/E架构。我们解释了这样的设计目标的动机，并讨论了两种不同设置（即基于CAN总线和FlexRay总线的系统）下可扩展性度量的定义和可扩展性驱动的设计方法。基于这两个例子，我们说明了可扩展性驱动的设计在汽车E/E架构的重要性和优势。
Increasingly more software-based applications are being developed and deployed in modern vehicles. As a result, the extensibility of a system design has become an important issue in order to accommodate more future applications and update of existing ones on one hand and reduce the effort and cost of re-design, test and validation on the other. In this paper, we discuss the extensibility-driven design in the automotive E/E architecture. We explain the motivation for such a design objective and discuss the definition of extensibility metric and extensibility-driven design methods under two different setting, namely the system based on CAN bus and FlexRay bus. Based on these two examples, we illustrate the importance and advantages of extensibility-driven design in the automotive E/E architecture.
