随着汽车电子化程度不断增长,汽车上使用了越来越多的微处理器来实现更加准确的控制和检测功能。随着基于处理器的电控单元功能越来越强大,其设计以及开发也随之变得复杂,因此需要有一个嵌入式操作系统来实现其复杂的功能。文中首先介绍了汽车行业嵌入式操作系统标准(OSEK/VDX)的组成及特点,然后参照该操作系统标准,设计了基于微内核结构的汽车专用嵌入式操作系统,在移植性、可靠性以及扩展性方面有了很大的提高。
As the level of automotive electronics continues to grow, more and more microprocessors are used in cars to provide more accurate control and detection capabilities. As processor-based ECUs become more powerful and their design and development become more complex, an embedded operating system is needed to accomplish its complex functions. Firstly, this paper introduces the composition and characteristics of OSEK / VDX (Automated Operating System) standard in the automotive industry. Then, with reference to this operating system standard, this paper designs a special embedded operating system for automotive based on microkernel structure, which has advantages in portability, reliability and expansion Sex has been greatly improved.
