Description
上記特許文献1に記載された電動車両においては、各駆動輪のタイヤが接地面において前後方向にすべること及び車両の加減速時の前後方向の荷重移動によりタイヤの横力が変化することについては考慮されていない。そのため、車両が一定の車速にて旋回する場合において各駆動輪のタイヤが接地面において横すべりすることにより消費されるエネルギーしか低減することができない。換言すれば、車両が加減速を伴って旋回する場合のように、各駆動輪のタイヤが接地面において前後方向にすべることにより消費されるエネルギーを低減することはできない。
本発明によれば、それぞれタイヤを有する左右前輪及び左右後輪と、前記四輪に相互に独立して駆動力を付与する駆動力付与装置と、を有する四輪駆動車両に適用され、前記駆動力付与装置を制御することにより前記四輪に付与される駆動力を制御する駆動力制御装置が提供される。
Claims (3)
- それぞれタイヤを有する左右前輪及び左右後輪と、前記四輪に相互に独立して駆動力を付与する駆動力付与装置と、を有する四輪駆動車両に適用され、前記駆動力付与装置を制御することにより前記四輪に付与される駆動力を制御する駆動力制御装置において、
前記駆動力制御装置は、前記四輪の位置における車体速度の情報を取得する装置と、前記四輪の接地荷重の情報を取得する装置と、運転者が前記車両に要求する要求駆動力の情報を取得する装置と、を有し、
前記駆動力制御装置は、前記四輪の位置における車体速度、前記四輪の接地荷重及び前記要求駆動力に基づいて、前記四輪のタイヤすべり速度ベクトルを同一にするための前記四輪の目標駆動力を演算し、前記四輪の駆動力がそれぞれ対応する前記目標駆動力になるように前記駆動力付与装置を制御する、駆動力制御装置。 - 請求項1に記載の駆動力制御装置において、前記駆動力制御装置は、前記四輪の前記目標駆動力のそれぞれが「対応する車輪の位置における車体速度に対する同対応する車輪の接地荷重の比」に比例し且つ前記四輪の前記目標駆動力の和が前記要求駆動力と一致するように、前記要求駆動力を前記四輪に配分することにより、前記四輪の前記目標駆動力を演算する、駆動力制御装置。
