Abstract
【解決手段】 横加速度の絶対値の増大時と減少時およびその方向に応じて、要求トルクTを求める際の横加速度G−要求トルクTの特性線図をA〜Dの間で切り替える。ここで、横加速度Gの絶対値が増大する場合に用いる線図A、Cは、減少する場合に用いる線図B、Dに比較して同一の横加速度G(G≠0)に対して要求トルクTの絶対値が大きくなるよう設定されている。また、同一の横加速度Gに対する線図Aと線図Bの差(線図Cと線図Dの差も同じ。)は、横加速度0近傍では、それ以外の領域より差が小さくなるよう設定されている。特に、横加速度Gが0のときに、要求トルクTが0となるよう設定されていると好ましい。

Description
Claims (3)
- 車両の目標横加速度を求め、この目標横加速度に応じて運転者の操舵力を補助するアシスト操舵力を付与する車両用操舵支援装置において、
任意の目標横加速度において付加するアシストトルクを、目標横加速度が減少状態のときより目標横加速度が増大状態の場合に大きく設定するとともに、目標横加速度が0近傍領域における目標横加速度が減少状態のときに付加するアシストトルクと目標横加速度が増大状態の場合に付加するアシストトルクの差をそれ以外の場合に比較して小さく設定することを特徴とする車両用操舵支援装置。 - 目標横加速度が0の場合の目標横加速度が減少状態のときに付加するアシストトルクと目標横加速度が増大状態の場合に付加するアシストトルクの差を0にすることを特徴とする請求項1に記載の車両用操舵支援装置。
- 目標横加速度の時間変化の推移を基にして、目標横加速度が減少から増加または増加から減少に切り替わった後、さらに同一傾向が続いている場合に増減方向の切り替えが行われたと判定することを特徴とする請求項1または2に記載の車両用操舵支援装置。
