A magneto-rheological semi-active suspension Smith interval type-2 fuzzy time delay compensation control method comprises a magneto-rheological semi-active suspension controller, and the magneto-rheological semi-active suspension controller comprises a Smith-interval type-2 time delay compensation controller, an ideal current solving unit and a current controller. A vehicle-mounted sensor measures to obtain a vehicle body vertical acceleration a1, a suspension dynamic deflection fd1, a tire dynamic load Fd1 and a relative speed vr, inputs the values to a Smith-interval type 2 time delay compensation controller, and inputs the relative speed vr to an ideal current solving unit; and the Smith-interval type-2 time delay compensation controller calculates to obtain compensated active control force F3 (t), and the compensated active control force F3 (t) is respectively input into the Smith-interval type-2 fuzzy control unit and the ideal current solving unit. According to the magneto-rheological semi-active suspension Smith interval type-2 fuzzy time delay compensation control method, a Smith pre-estimation control method and an interval type-2 fuzzy control method are combined, and the influence caused by pure hysteresis characteristics is reduced to a certain degree.
