In order to improve fuel economy and enhance operating efficiency of fuel cell hybrid\nvehicles (FCHVs), fuzzy logic control (FLC) strategies are available and suggested for adoption.\nIn this paper, the powertrain of a fuel cell hybrid vehicle is designed and the parameters of the\nmotor, battery, and fuel cell are calculated. The FLC strategy and the power following control\n(PFC) strategy are designed for the studied FCHV. A secondary development for Advanced Vehicle\nSimulator (ADVISOR) is implemented based on the standard driving cycles, and a Chinese typical\ncity driving cycle is imported. Simulation results demonstrate that the proposed FLC strategy is\nmore valid and reasonable than the traditional PFC strategy. The proposed FLC strategy affects the\nvehicle characteristics significantly and contributes to better performance in four aspects: fuel economy,\nefficiency of battery and fuel cell system, battery state of charge (SOC), and battery life. Hence, the FLC\nstrategy is more suitable for the energy management strategy for fuel cell and battery hybrid vehicles.
