Riding comfort improvement of small electric vehicle with active seat suspension

Abstract

To improve riding comfort of driver's seat, we have proposed active suspension system for heavy duty truck. In this study, the control mechanism of the active seat suspension was designed for a small vehicle like community car with using coefficient diagram feedback control method. The operability improvement for senior citizen, vibration isolation for baby and riding comfort improvement in the unpaved road can be expected. In order to examine the effectiveness of the system, experiments were performed for some road surface conditions.
