- 車両シートに着座した乗員を装着時に拘束し、非装着時に該乗員を開放するシートベルトと、
車両シートの着座面に作用する荷重を検出するために車両シートの後方に設けられた左右一対の2つの荷重センサからなる荷重検出装置と、
該荷重検出装置によって検出された荷重に応じて前記シートベルトの装着を促すウォーニング部材と、
着座なし状態であるとの認識状態である着座なし認識モードと、乗員の着座ありと判断し前記ウォーニング部材を作動許可状態とする乗員着座認識モードと、荷物の載置状態と判断し前記ウォーニング部材を作動不可状態とする荷物認識モードと、のいずれか1つのモードとする制御手段とを備え、
前記制御手段は、
前記着座なし認識モードにおいて前記荷重検出装置が第1荷重より大きく第2荷重より小さい荷重を検出したことを条件として前記荷物認識モードへ移行し、前記荷物認識モードにおいて前記荷重検出装置が所定の荷重より小さい荷重を予め設定された第1時間継続して検出したことを条件として前記着座なし認識モードへ移行する第1遷移処理と、
前記着座なし認識モードにおいて前記荷重検出装置が前記第2荷重より大きい荷重を検出したことを条件として前記乗員着座認識モードへ移行し、前記乗員着座認識モードにおいて前記荷重検出装置が前記所定の荷重より小さい荷重を前記第1時間継続して検出したことを条件として前記着座なし認識モードへ移行する第2遷移処理と、
を行うことを特徴とするシートベルトウォーニング装置。 - 請求項1において、前記制御手段は、
前記第1遷移処理時にあっては、前記着座なし認識モードにおいて前記荷重検出装置が第1荷重より大きく第2荷重より小さい荷重をイグニッションスイッチがON状態となってから予め設定された第2時間以内に検出した場合に、前記荷物認識モードへ移行し、
前記第2遷移処理時にあっては、前記荷重検出装置が前記第2荷重より大きい荷重をイグニッションスイッチがON状態となってから前記第2時間以内に検出した場合に、前記乗員着座認識モードへ移行することを特徴とするシートベルトウォーニング装置。 - 請求項1または請求項2において、車両が下り坂に停車していることを判定する下り坂判定手段と、該下り坂判定手段によって車両が下り坂に停車していると判定された場合には、その下り坂の程度に応じて前記荷重検出装置によって検出された荷重を補正する荷重値補正手段を備えていることを特徴とするシートベルトウォーニング装置。
- 請求項1ないし請求項3のいずれか1項において、前記制御手段は、荷物認識モードにおいて前記荷重検出装置が前記第2荷重より大きな所定の荷重を所定時間継続して検出した場合には、前記乗員着座認識モードへ移行する第3遷移処理を行うことを特徴とするシートベルトウォーニング装置。
