In passive suspension for automobiles, the ride comfort and the driving stability are a trade-off relationship and many studies of semi-active suspension have been performed in order to realize a high-level performance of both aspects. In this study, a semi-active suspension system of variable stiffness and damping is dealt with. For the semi-active control system, a disturbance accommodation frequency-shaped control method is proposed in order to improve both the ride comfort and the handling performance in a higher level. Furthermore, in order to present a method of determining the weightings in the criterion by the genetic algorithm, a parameter related to the ride comfort and the driving stability is introduced. By carrying out computer simulations, it is demonstrated that the proposed method is effective.
