Abstract
An increasing number of small-sized vehicles like a personal mobility are being developed these years since environmental and energy-saving performance have gained considerable importance on mobility developments. The feature of these vehicles is smaller and lighter than traditional vehicles. It is expected that motion of human body has a large influence on running performance of the vehicle, and this affects vehicle stability and human safety. This report 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. It is demonstrated that interactions between the vehicle model and the human model depend on vehicle spec and mass ratio.
