This paper describes an active control system aimed at minimizing vertical vibrations from the seat to the human body in a vehicle. This system controls mechanical properties such as spring constants and damping coefficients on the basis of vibration analysis. This study aimed to estimate a prototypic vehicle seat with air cushions. The cushion properties and effectiveness of the vibration reduction were examined by using the analytical system of a seat-steering wheel-occupant system while controlling the seat. The pressure control device and control program for the controlling cushion properties were estimated. In summary, the validity of the prototypic vehicle seat with air cushions is indicated.
