The invention provides a method and device for controlling the current of a magneto-rheological shock absorber, and the method comprises the steps: carrying out the indicator test of the magneto-rheological shock absorber, and obtaining a relation table between damping force and the speed of a piston and the current of a coil; redividing the scales of the piston speed and the damping force in therelation table to serve as independent variables, and generating an orthogonal independent variable group by taking the coil current as a dependent variable; carrying out first smooth interpolation processing on the orthogonal independent variable group near the test data point to obtain a first interpolation point, filtering the first interpolation point according to a filtering condition, and carrying out second smooth interpolation processing on the data point in the non-monotonic change area to obtain a second interpolation point; and after the upper limit and the lower limit of the current are set outside the upp
