Abstract
A small active seat suspension has been designed and manufactured for a one-seat electric vehicle. Our aim was to develop a vibration-isolation system for the driver's seat suspension using active control. However, the evaluation of ride comfort while the electric vehicle was running has depended on subjective judgement by drivers. Thus, it is necessary to evaluate the correlation of subjective judgement with objective judgement based on physical values, i.e., vibrations. In this study, we performed a sensory evaluation of riding comfort. In addition, the factors affecting the sensory evaluation value were examined by questionnaire investigation. As a result, we confirmed that the aggression and the private space function were correlations for the quality of riding comfort.
