A simulation model for fuel cell hybrid vehicle (FCHV) power train in parallel configuration based on MATLAB/Simulink has been constructed with the power control strategy using logic threshold approach achieved by the hybrid control unit (HCU). Using accelerator /decelerator pedal positions generated by the driver model as the system primary input, the simulation implements difference power distribution under six vehicle operating modes. The control strategy also incorporates regenerative braking and recharge for battery capacity recovery. Main control variables in HCU and their three group threshold values are evaluated for the vehicle driven under different driving cycle schedules. The results indicate that the configuration of the FCHV model has capability for drive power request while meeting vehicle speed and battery state of charge recovery.
