In recent years, several manufacturers have marketed small one or two-seater electric automobiles. We have examined the improvement of ride quality and the reduction of riding fatigue brought about by the active control of the seat suspension of small vehicles such as one-seater electric automobiles. 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. In this study, we performed a sensory evaluation of riding comfort for a small vehicle. In addition, the psychological factors affecting the sensory evaluation value were examined by multivariate analysis using cluster analysis. As a result, we confirmed personality influenced the quality of riding comfort, and the factor of personality that influenced riding comfort was able to be analyzed.
