本文成功地將符合OSEK/VDX 標準的嵌入式實時操作系統OSEK Turbo OS 應用到燃料電池城市客車整車控制器中。將控制程序劃分為合理的任務后，通過引入實時操作系統，采用基于優先級的搶占式調度方式構建控制軟件系統，不但提高了軟件的執行效率，保證了控制器的實時性要求，也提高了控制軟件的開發效率。在該實時操作系統的基礎上，成功地實現了對整車運行的管理與控制、基于CAN 總線的各部件節點的協調控制、故障診斷和處理及數據監控記錄等功能，順利完成了燃料電池城市客車整車控制器的開發。

Abstract: A real-time operating system “OSEK Turbo OS” which meets the OSEK/VDX standard has been implemented in the vehicle controller of a fuelcell city bus. Control parsers are divided into appropriate tasks, which are scheduled with priority preempt strategy by the real-time operating system. In this process, not only has the execution efficiency of software but also the development efficiency been improved, in the meantime, the real-time performance can be guaranteed. Vehicle control and management, components control via CAN bus, diagnosis, monitoring and etc. have also been successfully established in the
real-time system, implementing the vehicle controller of the fuelcell city bus.
