本文成功地将符合OSEK/VDX 标准的嵌入式实时操作系统OSEK Turbo OS 应用到燃料电池城市客车整车控制器中。将控制程序划分为合理的任务后，通过引入实时操作系统，采用基于优先级的抢占式调度方式构建控制软件系统，不但提高了软件的执行效率，保证了控制器的实时性要求，也提高了控制软件的开发效率。在该实时操作系统的基础上，成功地实现了对整车运行的管理与控制、基于CAN 总线的各部件节点的协调控制、故障诊断和处理及数据监控记录等功能，顺利完成了燃料电池城市客车整车控制器的开发。

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.
