Claims (1)
- エンジンによって駆動されるポンプからパワーステアリング出力部に導かれる作動油の流量QPを調節するフローコントロールバルブと、
車両に搭載される舵角センサによって検出される操舵角θに応じて流量QPを制御するコントローラとを備える車両のパワーステアリング装置において、
前記コントローラは、舵角θを基に舵角速度ω1を算出する舵角速度算出手段と、
舵角速度ω1を入力しカットオフ周波数fcより高い周波数成分をカットした信号を舵角速度ω2として出力するローパスフィルタと、
高速転舵時を検出する高速転舵時検出手段と、
この高速転舵時に前記ローパスフィルタのカットオフ周波数fcを高く変更するカットオフ周波数変更手段と、
舵角θと舵角速度ω2の少なくとも一つに応じて流量QPを制御する流量制御手段とを備え、
前記高速転舵時検出手段は舵角速度ω1がしきい値ω3より高い場合に高速転舵時と判定する構成とし、
前記舵角センサが前記舵角θを検出する舵角分解能をXとし、前記舵角速度ω1の演算周期をYとすると、前記しきい値ω3をX/Yより大きい値に設定し、
前記カットオフ周波数変更手段は、前記舵角速度ω1が前記しきい値ω3より高い高速転舵時に前記舵角速度ω1の信号を前記ローパスフィルタを経ずに導く状態に切り換える構成としたことを特徴とするパワーステアリング装置。
