Hybrid　Electric　Vehicle　(HEV)　is　considered　as　the　most　promising　solution　to　energy　crisis　and　urban　air　pollution.　However,　it　is　a　complex　electro-mechanical　system　which　is　difficult　to　construct　an　accurate　mathematical　model.　Fuzzy　logic　seems　to　be　appropriate　for　the　HEV　control　problem.　In　this　paper,　a　Fuzzy　Logic　Control　Strategy　(FLCS)　is　developed　for　a　series　hybrid　electric　vehicle　designed　for　campus　and　gymnasium.　Based　on　the　State-of-Charge　(SOC)　of　the　batteries　and　the　power　information,　the　power　required　by　the　vehicle　is　split　between　the　engine/generator　set　and　the　batteries　instantaneously　by　the　FLCS.　The　SOC　of　the　batteries　can　be　maintained　always　at　a　high　level　and　the　engine　can　steadily　work　in　its　high　efficiency　area.　A　forward　simulation　model　for　the　vehicle　is　established,　and　both　off-line　and　real-time　simulations　are　performed.　Simulation　results　show　that　the　FLCS　can　realize　constant　SOC　control,　and　fuel　consumption　and　emissions　are　also　considered　by　the　FLCS.
