The purpose of this study was to examine the effectiveness of active seat suspension when it is applied to small cars, and to survey the problems associated with its practical use. A small active seat suspension, which is easy to install, was designed and manufactured for one-seat electric automobiles. In a realistic driving t,est, a test road was prepared using hard rubber. The concavity and convexity of an actual road surface were simulated. Our aim was to develop a robust vibration-isolation system for the driver's seat using a sliding mode control, which tolerates such factors as variation of a parameter for the driver's weight. We performed experiments simulating several conditions, and compared the results obtained with optimal control results. The tests verified that the suppressive effect of the sliding mode control on the vibration isolation was effective.
