Description
補正量=K1×(エンジン回転速度)-1
−K2×吸気圧
+K3×(吸気温)-1
+K4×アクセル開度
を用いるようにする。K1〜K4は係数である。補正量演算式中の加減乗除、指数及び係数K1〜K4の値は、理論あるいは実験によって決定するとよい。燃料流量上限を求めるためのエンジンパラメータは、この例に限らず、3種類以下でもよく、5種類以上でもよい。
2 エンジン
6 ターボチャージャ
9 DPF
23 ECU
Claims (1)
- エンジン回転速度の低域にスモークリミットを設定し、燃料流量をスモークリミットで制約する車両の坂路発進支援方法において、
スモークリミットとして、通常発進用スモークリミットと通常発進用スモークリミットより燃料流量上限が大きい坂路発進用スモークリミットとを設定し、
前記坂路発進用スモークリミットを、エンジン回転速度が低下するにつれ、坂路発進用の燃料流量上限と通常発進用の燃料流量上限との差分が増大するよう設定し、
登坂路での車両停止の状態から所定時間内にエンジンへの要求が全負荷要求に移行したとき、車両が坂路発進中と判定し、燃料流量を坂路発進用スモークリミットで制約する坂路発進支援方法。
