Control method for improving driving comfort of cross-country vehicle

The invention relates to the technical field of automobile control methods, in particular to a control method for improving the driving comfort of a cross-country automobile. The method comprises steps of acquiring a vertical acceleration signal of the vehicle body, acquiring a vertical acceleration root-mean-square value and a root-mean-square value change rate of the vehicle body based on the vertical acceleration signal, acquiring a vibration frequency and a vibration frequency change rate corresponding to the maximum power spectrum, and performing two-dimensional damping fuzzy control on the basis of the vertical acceleration root-mean-square value and the root-mean-square value change rate to obtain optimal damping; performing two-dimensional rigidity fuzzy control on the basis of the vibration frequency corresponding to the maximum power spectrum and the vibration frequency change rate to obtain the optimal rigidity; correcting the optimal damping and the optimal rigidity to obtain target damping and ta
