In　the　paper,　a　fuzzy　logic　control　scheme　of　the　Magnetorhelogical　(MR)　semi-active　suspension　was　proposed,　to　reduce　the　fluctuation　of　dynamic　tires　load,　which　improves　the　vehicle.　stability　and　anti-lock　braking　system　(ABS)　performance.　A　half　car　nonlinear　vehicle　dynamics　model　with　four　degree　of　freedom　was　developed　along　with　models　for　a　MR　damper　and　a　hydraulic　ABS　system.　Individual　fuzzy　logic　controllers　was　constructed　for　each　subsystem.　Influences　of　road,　surface　roughness　on　ABS　performance　were　investigated.　Simulation　study　results　demonstrate　that　the　integrated　controllers　significantly　improve　the　vehicle　stability　and　ABS　performance　during　emergency　braking.
