摘　　要：燃料电池城市客车的部件繁多,结构复杂,包括燃料电池发动机、蓄电池、DC/DC和电动机等多个部件节点,其控制系统多采用复杂的分布式控制系统。该控制系统信息流量大、控制任务复杂、实时性要求高,在开发与运行过程当中对数据监控、故障诊断、程序在线更新、数据传输等都提出了更高的要求。在燃料电池城市客车控制系统研发与装备过程中,采用了OSEK/VDX标准的实时操作系统、硬件在环实时仿真、时间触发控制器局域网(Controller area network,CAN)以及无缝自动代码生成等最新的软件技术,这些新技术的应用,有效地提高了燃料电池客车控制系统的开发效率,降低了系统故障率,并为燃料电池客车的优化控制构建了一个开放的技术平台。The fuel cell city bus has become a favorite choice for new energy vehicle due to its free of emission, high energy conversion efficiency as well as long driving endurance. A fuel cell city bus consists of varied components, including fuel cell stack, power battery, DC/DC converter and electronic motor etc. A complex distributed control system is implemented for the fuel cell bus which has been facing the challenge of mass data transmission, complex control task, high quality real-time operation, system monitoring, in-system self programming and etc. The integrated application and implementation of a series of novel software technology in the control system development of the fuel cell city bus are presented in order to meet the requirements of the challenges, including OSEK/VDX RTOS, hardware-in-the-loop real-time simulation, time trigger controller area networks and seamless automatic code generation. These new technologies promote the development efficiency of the fuel cell control system, reduce system fault rate dramatically, and provide an open technology platform for fuel cell city bus control strategy optimization.
