Abstract :
A distributed control system comprising a TTCAN (Time Triggered Controller Area Network) and a J1939 CAN (Controller Area Network) is proposed for a PEM (Proton Exchange Membrane) fuel cell / Ni-MH battery hybrid vehicle. A current-regulated DC/DC (Direct Current to Direct Current converter) is used to control the output power of the fuel cell. The work of the hybrid power train is coordinated by the TTCAN network, incorporating an optimal energy management strategy and a brake energy regeneration algorithm. In order to keep the vehicle safe, another CAN network based on the SAE (Society of Automotive Engineers) J1939 protocol is designed to coordinate the work of the braking energy regeneration algorithm and the ABS. Results of the city bus in the ldquoChina typical city bus cyclerdquo are presented.
