立ち乗り式四輪車両の自動加減速時における操縦者の挙動

抄録

In recent years, personal mobility vehicles (PMVs) have been developed. PMVs have various types, such as an inverted pendulum type vehicle, a four-wheel sitting type vehicle, a four-wheel stand-up type vehicle and so on. In this study, we focus on a four-wheel stand-up type vehicle because of its static stability, its compact size and its easiness to ride. In this study, we aim to enhance the safety of a PMV by using driving support systems, for example, automatic braking and self-driving. However, a driver has a possibility to fall down due to driver's behavior or a method of driving support. It is because the mass of a driver is comparatively larger than that of a PMV. In this study, we carried out the deceleration experiments to confirm the behavior of the driver, 1: intentional brake by himself, 2: brake by driving support system. As a result, it was found that the driver's behaviors under the condition 1 and 2 are significantly different.
