摘　　要：OSEK/VDX是目前通用的汽车电子开放式软件接口。为了实现对混合动力汽车系统的实时控制,在控制策略的实现上有必要加入实时操作系统,以提高系统的响应速度,实现系统的模块化设计。阐述了混合动力系统的结构、系统的硬件构成以及嵌入式软件设计方法。以S12X为主芯片的硬件平台为RTOS的实现提供了硬件保证。软件设计方面阐述了实时内核的设计、基于数据流和主工况状态机的任务划分方法、CAN通信程序的设计等实时操作系统的构建方法。OSEK/VDX is the common software interface in the area of automotive electronics. It is necessary to build a real time operating system in order to achieve the real time control of hybrid electric vehicle control system. Real-time operating system can improve the response rate of control system and is easy to implement design modularity. The structure of HEV system, hardware of system and embedded software design were introduced. Design of real-time operating system kernel and methods of task were divided base on the data flow and main state machine, and CAN communication program was presented. A real-time operating system has been built based on the interface OSEK/ VDX.
