- 車両の運転者が疲れているときを検出する方法であって、
前記疲労はステアリング動作のない段階及びその後のステアリング動作に応じて判断され、
この場合、前記ステアリング動作のない段階が、前記ステアリング動作に論理的に結合され(ステップS4)、前記論理結合が、複数の時間(Ti)に格納され、
前記論理結合が、割り当てられた重み係数を付けて格納され(ステップS6)、
前記重み係数が、ステアリング状況の分類に応じて決定され、
前記ステアリング動作が、前記ステアリング状況中に行われることを特徴とする方法。 - 前記車両のハンドルの動きが、ハンドル角(x)として感知される(ステップS1)ことを特徴とする請求項1に記載の方法。
- ステアリング動作のない段階が検出され、前記ステアリング動作のない段階の大きさが、前記ハンドル角が所定のハンドル角間隔(ΔX)内にある時間帯として得られる(ステップS2)ことを特徴とする請求項1或いは2に記載の方法。
- 前記ステアリング動作のない段階の後に続くステアリング動作が検出され、前記ステアリング動作の大きさが、前記ハンドル角の最大勾配の形で取得される(ステップS3)ことを特徴とする請求項1、2、或いは3に記載の方法。
- 前記ステアリング動作のない段階の大きさと前記ステアリング動作の大きさとの論理結合が、所定の測定時間間隔中の異なる時間(Ti、i=[1、2、...I]))に行われることを特徴とする請求項1、2、3、或いは4に記載の方法。
- 前記ステアリング状況が、車両内の複数のセンサからのデータを用いて及び/又は車両内の操作者制御介入に関係するデータを用いて、時間(Ti)で分類されることを特徴とする請求項1〜5のいずれか一項に記載の方法。
- 前記論理結合の重み付けされた結果の計算が、割り当てられた重み係数による、前記測定時間間隔中に格納された結果の、数学的な、好ましくは相加重み付け平均によって行われる(ステップS7)ことを特徴とする請求項1〜6のいずれか一項に記載の方法。
- 所要時間である前記ステアリング動作のない段階の大きさが所定の最小所要時間より長く、かつ前記ハンドル角の最大勾配が所定の勾配閾値を超えた場合に、前記論理結合が、時間(Ti)に行われることを特徴とする請求項1〜7のいずれか一項に記載の方法。
- 前記ステアリング状況が、3つのクラスのステアリング状況に分類されることを特徴とする請求項1〜8のいずれか一項に記載の方法。
- 前記ステアリング状況の前記分類中に、疲労によって引き起こされたステアリング状況、注意散漫によって引き起こされたステアリング状況、及び/又は環境によって引き起こされたステアリング状況が識別され、分類されることを特徴とする請求項1〜9のいずれか一項に記載の方法。
- 注意散漫によって引き起こされたステアリング状況及び環境によって引き起こされたステアリング状況の重み係数が、疲労によって引き起こされたステアリング状況の重み係数より低いことを特徴とする請求項10に記載の方法。
- 車両の運転者の疲労を検出するための制御ユニット(100)であって、
前記車両の現在のハンドル角を感知するためのハンドル角センサ(110)と、
前記感知されたハンドル角に応じて、請求項1〜11のいずれか一項に記載の方法を行うための制御装置(120)、好ましくはマイクロコントローラと、
本方法が行われている間に前記運転者の疲労が検出された場合に、音による及び/又は視覚的な警告メッセージを前記運転者に出力するための警告装置(130)と、
さらなるセンサ(112、114)とを有する制御ユニット(100)。
