The invention provides an automotive body gesture decoupling control method, comprising the following steps: utilizing an acceleration transducer and a gyroscope to extract an automotive body motion gesture signal in travelling process of an automobile; carrying out decoupling analysis on the automotive body gesture; decomposing the coupling motion into vertical motion, pitching motion and heeling motion; dividing the automotive body into different modules aiming at each motion; adopting parameters to self adjust fuzzy strategy and proposing a power applying scheme for each suspension; evaluating the scheme according to a suspension utility function; optimizing three types of powers needed in inhibiting the vertical motion, the pitching motion and the heeling motion by adopting a simple golden cut algorithm to finally obtain power output by each active absorber realizing a total control target, thus improving the automotive ride and stability, and simultaneously leading the active suspension to obtain good effect and instantaneity.
