| Abstract(J) | 前報で人－自動車系の評価で前後輪の横剛性差が進路変更時の動的安定性に大きく影響する事が分かった。本報では横剛性差による特性方程式の根軌跡が車速、人の遅れ時間、注視距離等によらず、前輪＞後輪では動的安定性ζが高く、前輪＜後輪ではζ小、前輪＝後輪及び、前後共∞では中間値近傍を維持するという事が分かった。 Translation |
| Abstract(E) | The previous paper reported that the difference between front and rear wheel lateral stiffness has a significant effect on the dynamic stability at directional change when evaluating with man-vehicle system. This paper reports that the root locus of the characteristic equation according to the difference of the lateral stiffness is independent from the vehicle speed, human delay time, or preview distance, and the dynamic stability ζ is high when the front wheel>the rear wheel, low when front<rear, and stays close to the middle value when front=rear, or front and rear are both infinity. |
