| Abstract(E) | In four-wheeled vehicles, an imbalance between front and rear roll moments and roll stiffness influences steer characteristics through changes in tire vertical load. However, few studies have logically analyzed the effect of body rigidity on vehicle handling characteristics. Especially for three-wheeled PMVs (Personal Mobility Vehicles), no research has been conducted. Therefore, this study first organizes the effect of body rigidity on tire vertical load in four-wheeled vehicles using a simplified body rigidity model. Based on this, we examined the influence of body rigidity on vehicle dynamics in a three-wheeled PMV with two front wheels and one rear wheel equipped with an active tilting mechanism. The results suggest that an optimal torsional rigidity around the vehicle’s longitudinal axis may exist for transient tasks in real-world scenarios, such as obstacle avoidance. Although no clear optimal value was found in simulations conducted using a vehicle dynamics analysis tool, it was observed that obstacle avoidance capability saturated at around 70% of the torsional rigidity typical of monocoque structures, confirming the impact of torsional rigidity on vehicle dynamics and validating the effectiveness of using a simplified body rigidity model for dynamic analysis as conducted in this study. |
