- 車両に搭載された内燃機関の点火時期を制御するための内燃機関の点火時期制御装置であって、
前記内燃機関の始動中に実行される複数回の燃焼のための複数の点火時期を設定する点火時期設定手段を備え、
当該点火時期設定手段は、
前記複数の点火時期のうち、先行側の点火時期である先行点火時期を、当該先行点火時期による燃焼によって上昇する前記内燃機関の回転数のピークが、当該内燃機関の回転に伴う振動によって前記車両が共振する所定の共振回転数域を下回るように、所定の基準点火時期よりも遅角側に設定し、前記先行点火時期の後続側の点火時期である後続点火時期を、当該後続点火時期による燃焼によって上昇する前記内燃機関の回転数のピーク、及び当該ピークから落ち込んだ前記内燃機関の回転数のボトムが、前記共振回転数域を超えるように、前記先行点火時期よりも進角側に設定することを特徴とする内燃機関の点火時期制御装置。 - 前記内燃機関の温度を表す温度パラメータを取得する温度パラメータ取得手段をさらに備え、
前記基準点火時期は、前記内燃機関の最大の出力トルクが得られる最適点火時期に設定されており、
前記点火時期設定手段は、前記取得された温度パラメータで表される前記内燃機関の温度が高いほど、前記基準点火時期に対して前記先行点火時期をより遅角側に設定することを特徴とする、請求項1に記載の内燃機関の点火時期制御装置。 - 前記点火時期設定手段は、前記温度パラメータで表される前記内燃機関の温度が高いほど、前記先行点火時期を徐々により遅角側に設定することを特徴とする、請求項2に記載の内燃機関の点火時期制御装置。
- 車両に搭載された内燃機関の燃焼のための点火時期を制御するための内燃機関の点火時期制御装置であって、
前記内燃機関の始動中、1回目の点火時期を、当該1回目の点火時期による燃焼によって上昇する前記内燃機関の回転数のピークが、当該内燃機関の回転に伴う振動によって前記車両が共振する所定の共振回転数域を下回るように、所定の基準点火時期よりも遅角側に設定し、2回目の点火時期を、当該2回目の点火時期による燃焼によって上昇する前記内燃機関の回転数のピーク、及び当該ピークから落ち込んだ前記内燃機関の回転数のボトムが、前記共振回転数域を超えるように、前記設定された1回目の点火時期よりも進角側に設定する点火時期設定手段を備えることを特徴とする内燃機関の点火時期制御装置。
