Road surface self-adaptive semi-active suspension control method and system

The invention relates to a road surface self-adaption semi-active suspension control method and system. The method comprises the following steps that firstly, road surface unevenness parameters of a current road surface are calculated according to operation parameters of a controlled automobile; step 2, calculating an equivalent damping coefficient optimization value of the adjustable damping shock absorber according to the road surface unevenness parameter calculated in the step 1; and 3, adjusting the current or electromagnetism of a driving control unit of the adjustable damping shock absorber according to the equivalent damping coefficient optimization value, calculated in the step 2, of the adjustable damping shock absorber. The system comprises a road surface unevenness parameter detection module, an adjustable damping shock absorber equivalent damping coefficient optimal value calculation module and an adjustable damping shock absorber optimal current or electromagnetic output module. The method can ad
