摘　　要：OSEKTime规范提出了基于时间触发操作系统与基于OSEK/VDX标准实现的操作系统的共存模型。在分析OSEKTime规范的基础上,针对该规范的消息触发任务存在着非实时性问题,提出并实现了一种合理的、能与OS-EK OS共存的实时时间触发操作系统,确保了时间触发任务的实时性和对消息触发任务的死限时间内的及时处理。OSEKTime specification proposes the coexistent model based on the time triggered operation system and the operation system realized by OSEK/VDX standard. Based on the analysis of OSEKTime specification, a reasonable and improved operation system based on real time triggered was presented to overcome the limitations in its message triggered task and the problem of coexistence between OSEKTime OS and the OSEK/VDX standard. The experiment indicates that it guarantees time triggered task real time and processes the message triggered task in deadtime.

关 键 词：OSEK/VDX标准 OSEKTime规范 时间触发 消息触发
