Study on Scheduling Design of TTCAN Protocol of Fuel Cell Bus
Fuel cell buses are the research focus all over the world, how to develop the application layer protocol of the powertrain systems is a key technique. According to the cummunication requirement of the powertrain system of 60kW fuel cell middle bus designed by our group, the time triggered CAN(TTCAN) protocol based on SAE J1939 was designed in this paper. In which, the redundant CAN Buses topology structure of powertrain system was established, then the source address, output parameters and parameter groups of each node were defined, and the TTCAN matrix was scheduled with average-loading algorithm. Finally, the analysis and testing results related to the schedulability, real-time capability, period dithering and bandwidth utilization performance were presented, which prove the good effect and validity of the method adopted in this paper.
