Abstract

　本発明の半クラッチ状態判定装置は、車両停止中にエンジン回転数が低下したときに、当該エンジン回転数の高周波成分と低周波成分とをなまし処理にて抽出し、その抽出した高周波成分と低周波成分とを積算して高周波成分の軌跡長と低周波成分の軌跡長とを算出する。そして、算出した高周波成分の軌跡長と低周波成分の軌跡長との関係から半クラッチ状態であるか否かを判定する。具体的には、高周波成分の軌跡長と低周波成分の軌跡長とパラメータとし、半クラッチ判定領域が設定された２次元マップ（図５）を用い、その２次元マップに、前記高周波成分の軌跡長及び低周波成分の軌跡長をプロットし、そのプロット点が半クラッチ判定領域内に入っているか否かにより、半クラッチ状態であるか否かを判定する。
