This paper presents new vibration control system considering psychological state of drivers. Low-speed vehicles such as ultra-compact vehicle have problems of ride comfort. In order to improve the ride comfort of ultra-compact mobility, we had proposed active seat suspension to control a vibration of seat section. In addition, it is possible that the vibration is controlled considering psychological state by the active seat suspension. It is necessary to improve the ride comfort by controlling the vibration in consideration of the psychological characteristics of the occupant against the vibration. Therefore, vibration control system using bioinstrumentation was experimentally investigated effects to ride comfort. This system switch ride comfort using psychological state analyzed in constant interval. The electrocardiogram was used to analysis for ride comfort and fed back to control system in this paper. Psychological state of driver was improved by switching ride comfort considering electrocardiogram.
