Abstract: According to the V-Type process, the vehicle electronic controller (VCU) of the fuelcell hybrid city bus is developed. Following the different stages in the V-cycle, the key problems of the controller based on the 32 bits MCU are analyzed and discussed. Not only the EMC, temperature and vibration test standard of the VCU are established, but also the platform of test and debug system of the VCU is constructed. The platform is helpful to evaluate and design the VCU. The technologies of algorithms GUI design, OSEK application, ISP, Monitoring technique and network communication of the VCU are explored.

Key words: Vehicle control unit  V-type procedure  Fuel cell hybrid system  Distribute control system
