In order to develop more scientific LQG (Linear-Quadratic Gaussian) optimal controller of vehicle active suspension, based on vehicle system dynamics and modern control theory, the LQG controller of one 4-dof active suspension vehicle model was presented. And the index weighting coefficiens in LQG controller were rationally determind by AHP (Analytic Hierarchy Process) method. Based on this, for furtherly improving vehicle performanc, the subjective important degrees in AHP method were optimized by OT (Othogonal Test) method which took the linear weighted sum of ride comfort and road friendliness index as the comprehensive performance evaluation index. The simulation results showed that, compared to AHP method, the LQG active suspension vehicle designed by OT-AHP (Orthogonal Test of Analytic Hierarchy Process) method could have better comprehensive performance, which could provide new ideas for the development of vehicle active suspension.
