The small electric automobiles are different from conventional cars and are frequently driven on narrow roads and bad roads. Therefore, we suggest active seat suspension to improve the ride comfort during driving on a bad road, as a high value-added product. One-passenger electric automobiles can be equipped with the actuator of active seat suspension with a voice coil motor. The purpose of this study was to evaluate the utility and the effectiveness of the active seat suspension. We prepared a trade-off curve of the standard deviation of the bearing surface absolute acceleration and the standard deviation of the control voltage to compare the control performances and examined the ride comfort with the active seat suspension. As a result, we confirmed that the active control was passive, and we compared it by using time histories of the acceleration and power spectrum density. There was a reduction of the bearing surface absolute acceleration. Furthermore, p.-synthesis confirmed that the performance for the control voltage was the best from the trade-off curve.
