| Abstract(J) | 著者は操舵感を，①準静的な角度＝力特性，②ハンドルに伝わる後輪横力，③操舵トルクに対するハンドルの応答の3つに分類している．最後はフォースコントロールと呼ばれ，その特性方程式は操舵系と車両系とが連成によって4次方程式になる．これらの共振周波数の高精度の近似式の定式化に直観が使われた．本報では，この公式を理論的考察に基づいて導くと共に，さらに近似精度を向上させた． Translation |
| Abstract(E) | The author classifies steering feel into three components: 1) the quasi-static angle–force characteristics, 2) the rear-wheel lateral force transmitted to the steering wheel, and 3) the steering wheel's response to steering torque. The last component is referred to as force control, whose characteristic equation becomes a fourth-order equation because the steering system and the vehicle system are coupled. Intuition was used in formulating high-accuracy approximation formulas for their resonance frequencies. In this paper, we theoretically derive these formulas based on analytical considerations and further improve their approximation accuracy. |
