前記周波数設定手段は、高速走行時には操縦安定性が向上し、低速走行時には乗り心地が向上するように、前記車速が大きい場合は小さい場合に比べて前記周波数を高い値に設定するように構成されたことにある。
この場合、前記周波数設定手段は、前記サスペンションラバーブッシュのバネ定数が、前記車速に応じて設定される目標バネ定数となるような周波数を前記周波数として設定するとよい。
また、本発明の特徴は、車両が、
車両の走行状態に関連する状態量である走行状態量を取得する走行状態量取得手段(74)と、
サスペンションラバーブッシュの減衰係数を変更させるための振動を前記サスペンションラバーブッシュに付与する振動付与手段(30,200)と、
前記走行状態量取得手段によって取得された走行状態量に基づいて、前記サスペンションラバーブッシュに付与する振動の周波数を設定する周波数設定手段(112,113,114,151)と、
前記周波数設定手段によって設定された周波数の振動を前記サスペンションラバーブッシュに付与するように前記振動付与手段の作動を制御する振動制御手段(104,105,152)と
を備えた車両であって、
前記走行状態量取得手段は、前記走行状態量として前記車両の車体の姿勢変化率(G)を取得し、
前記周波数設定手段は、前記姿勢変化率が大きい場合には操縦安定性が向上し、前記姿勢変化率が小さい場合には乗り心地が向上するように、前記姿勢変化率の大きさが大きい場合は小さい場合に比べて前記周波数を高い値に設定するように構成されたことにある。
一方、前記周波数設定手段は、前記サスペンションラバーブッシュの減衰係数が、前記車体の姿勢変化率に応じて設定される目標減衰係数となるような周波数を前記周波数として設定することもできる。
また、前記周波数設定手段は、十数Hzから100Hzの範囲で前記サスペンションラバーブッシュに付与する振動の周波数を設定するように構成されるとよい。
前記振動付与手段は、前記車両の車輪に組み込まれ且つ前記車輪を回転させる駆動力を発生するモータ(30)であり、
前記振動制御手段は、前記駆動力を前記周波数設定手段によって設定された周波数で振動させるモータ制御手段(100)であることにある。
前記モータ制御手段は、ドライバー操作量に応じて前記モータの目標駆動力(F*)を決定し(101)、前記設定された周波数の振動成分(Fv)を前記決定した目標駆動力に重畳することにより最終的な目標駆動力を決定し(104,105)、前記最終的な目標駆動力に基づいて前記駆動力を制御するように構成されたことにある。
次に、ECU100の実施するモータ制御処理について説明する。このモータ制御処理については、3つの実施例について説明する。図3は、第1モータ制御例に係るECU100の機能ブロック図である。各機能部の処理は、ECU100のマイクロコンピュータにより所定の短い演算周期にて繰り返し実施される。
1.サスペンションブッシュ40に微小な振動を入力し、この振動の周波数を制御することでサスペンションブッシュ40の特性(バネ定数および減衰係数)を変更することができる。従って、簡易な構成でサスペンション特性を調整することができ、乗り心地および操縦安定性を向上させることができる。
次に、ECU100の実施する第2モータ制御例について説明する。図4は、第2モータ制御例に係るECU100の機能ブロック図である。各機能部の処理は、ECU100のマイクロコンピュータにより所定の短い演算周期にて繰り返し実施される。尚、第1モータ制御例と同じ機能部については、第1モータ制御例と同じ符号を付して説明を省略する。
次に、ECU100の実施する第3モータ制御例について説明する。図5は、第3モータ制御例に係るECU100の機能ブロック図である。各機能部の処理は、ECU100のマイクロコンピュータにより所定の短い演算周期にて繰り返し実施される。尚、第1モータ制御例と同じ機能部については、第1モータ制御例と同じ符号を付して説明を省略する。
次に、第2実施形態に係る車両について説明する。図7は、第2実施形態のインホイールモータ駆動方式の車両2の構成を概略的に示している。第1実施形態においては、モータ30の駆動力を振動させることによりサスペンションブッシュ40に振動を入力する構成を採用しているが、この第2実施形態においては、モータ30に代えて、振動発生装置200を使ってサスペンションブッシュ40に振動を入力する。従って、第2実施形態の車両2は、車輪10、サスペンション20、モータ30、モータドライバ35、ステアリング装置50、および、センサ71〜74に関しては、第1実施形態の車両1と共通する。第1実施形態の車両1と相違する点は、第2実施形態の車両2が振動発生装置200を備えていること、および、ECU100に代えてECU150を備えていることである。
