Description
出力信号のレベルが本制御アルゴリズムを実行すべき閾値を超える場合には(ステップS4;Yes)、速度センサ5の出力から車両の走行速度の読取りを行い(ステップS10)、車両速度をレジスタに記憶する(ステップS12)。CPUは車両速度をレジスタ値と比較して、車両速度が高速か、中速か、低速かを判別する(ステップS14,S30,S40)。
したがって、全ての車速に対して同一の閾値によって判別することが可能である。
図14及び図15は、サテライトセンサ2の出力信号(加速度信号あるいは減速度信号)の積分値(速度信号)に基づいて衝突判別を行う場合の制御系の動作を説明する第2実施例のフローチャートである。第2の実施例では、時間経過と共に閾値VT(t)を変化させることができる。また、車両速度に対応して閾値関数VT(t)が選択される。
