Description
図1に示されているルーチン1は開始点2とそれに続く分岐ステップ3を有しており、この分岐ステップ3では自動車の駆動輪の接地力ないしグリップ力が低下しているか否かが決定されている。例えばここではブレーキスリップ量BSが所定の値S、例えば30%を上回っているか否かが検査されるか、あるいはホイール回転数の勾配が負の方向で最大値を超えたか否か(減速状態か否か)が検査される。これらの条件が満たされない場合には、当該ルーチン1は終了点4にて終了する。グリップ力が低下すると、つまり例えばブレーキスリップ量BSが所定の値Sを上回ってしまうと、分岐ステップ5において、2つのクラッチがトルクを伝達しているか否かが決定される。ブレーキスリップ量の検出はホイール回転数センサの評価を介して行われるか又は変速機出力軸の回転数と走行速度の相関付けによって行われる。
