Abstract
An increasing number of small-sized vehicles like a mobility scooter are being developed these years since environmental and energy- saving performance have gained considerable importance on mobility developments. When the mass of a vehicle becomes small, it is expected that motion of human body has a large influence on running performance of the vehicle, and this affects vehicle safety. Accordingly, it is important to study effects of mass ratio of a vehicle and a human on driving stability by focusing on interactions between them. This study for a personal mobility evaluation examines interactions between a vehicle and a human from simulation results by a simulation model that consists of a vehicle model like a personal mobility and a human model that expresses human motion.
