電気自動車における車速認知性および快適性を両立するステアリング共振の検討

抄録

In this study, we focused on steering vibration characteristics as important information of electric vehicle speed information. On the other hand, the vibration may disturb the comfortableness in cabin. We then conducted subjective evaluation test by reproducing steering vibration considering the resonance characteristic using a driving simulator and attempted to propose appropriate vibration characteristics compatible the performance with comfortableness. As a result, both vehicle speed recognition performance and comfortableness were found to be better by controlling the resonance frequency and the level at a suitable condition.
