Description
前記開閉動作に応じて前記液圧発生手段が作動状態となってから、前記IGスイッチがオフ状態となっている状態が所定時間(前記制限時間)継続した場合に、前記液圧発生手段を作動停止状態に(シャットダウン)する条件付停止手段とを備えた制動力発生装置において、
前記条件付停止手段は、前記オン状態が取得不可と判定されれば、前記開閉動作に応じて前記液圧発生手段が作動状態となってから、前記イグニションスイッチがオフ状態となっている状態が所定時間継続した後も、前記液圧発生手段の作動状態を維持することを特徴としている。
図1に、本発明の第1の実施形態に係る制動力発生装置1の構成図を示す。制動力発生装置1は、ブレーキペダル3と、ホイールシリンダ4a、4b、4c、4dと、運転者によるブレーキペダル3の操作により液圧を発生可能なタンデム式のマスタシリンダM/Cと、マスタシリンダM/Cの第1液圧室24と複数のホイールシリンダ4a、4b間とを接続する第1液圧系統の液圧路17a−18a−19a、17a−18a−19bと、マスタシリンダM/Cの第2液圧室26と複数のホイールシリンダ4c、4d間とを接続する第2液圧系統の液圧路17b−18b−19c、17b−18b−19dとを有している。
図4に、本発明の第2の実施形態に係る制動力発生装置1が実施する制動力発生方法のフローチャートを示す。第2の実施形態でも、第1の実施形態の制動力発生装置1を用いることができる。第2の実施形態のステップS1〜S3とS8は、第1の実施形態のステップS1〜S3とS8と同じなので説明を省く。第2の実施形態では、ステップS3の次に、ステップS14に進む。
