Outline of Final Research Achievements

In this study, the dynamic motion of the lightweight personal mobility vehicles (PMVs) and a human was investigated. As forms of PMVs, an inverted pendulum vehicle and a four-wheel stand-up type vehicle were focused on. The numerical model of an inverted pendulum vehicle which moves according to the movement of a driver’s center of gravity was constructed by using multibody dynamics. From the proposed numerical simulations and the experiments using the three-dimensional analysis system, the influence of the shapes of the vehicle on the human behavior and the vehicle motion was shown. Further, the four-wheel stand-up type vehicle that is one example of a vehicle with static stability was modeled with a driver as a coupled model. The simulation results showed the design guidelines, such as the wheelbase of the vehicle and the handle position.
