N2 - This research aims at establishing an integrated control design method for the full-vehicle active-suspension system which can adapt to driving conditions and improve both ride comfort and driving stability. In order to improve driving stability, the proposed method is considered not only changes in vehicle body attitude but also vehicle motion in horizontal direction, such as yaw rate and lateral acceleration. Additionally, based on findings from a research of the driver's feeling characteristics, new control method for vehicle attitude is proposed. Moreover, the gain-scheduling algorithm that decides the balance of frequency weights with evaluation of driving condition based on several state quantities on vehicle is proposed. The numerical simulations with different road surface and operation conditions are carried out. As a result, it is confirmed that the proposed method has superior controlled performance compared with the passive suspension and.
