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.
