Abstract
The "community car" has been attracting attention as a transportation vehicle aimed at increasing the comfort of and convenience of daily life in the 21st century. In addition, the spread of "silver vehicles, " marketed mainly for elderly people, has been notable recently. It is expected that the demand for small electric automobiles will increase yearly, and the development of increasingly value-added products is expected. The purpose of this study is to examine the effectiveness of active seat suspension when it is applied to small cars and the problems associated with its practical use. A small active seat suspension, which is easy to install, was designed and manufactured for one-seater electric automobiles. In an actual driving test, a test road in which the concavity and convexity of an actual road surface were simulated using hard rubber was prepared and control performance of vertical vibrations of the seat surface using sliding mode control theory during driving was examined.
