摘　　要：针对汽车车身控制模块可调度性难以预测分析的问题,利用AADL建立相应模型,通过OSATE工具对比分析不同的派遣协议、执行时间、线程周期对任务及系统可调度性的影响,借助Cheddar工具给出任务在仿真时间内的详细调度甘特图。结果表明:此方法能准确、快速、直观地进行可调度性判定,方便设计者在设计初期对系统进行优化分析。In view of the unpredictable schedulability analysis problem of the body control module, themodel was established based AADL. The impact of the different dispatch protocol, execution time andthread cycle on the task scheduling was comparatively analyzed through OSATE tool. The task schedulingGantt charts in simulation time were given through the Cheddar tool. The results show this method can ac-curately, quickly and intuitively make schedulability determination, and it provides a new way for schedu-lability analysis and optimization in the system design.
