Abstract
【解決手段】「パワーOFF制御」から「パワーON制御」へ切替えるためのしきい値α1と、「パワーON制御」から「パワーOFF制御」へ切替えるためのしきい値α2とによって、切替条件が規定される。変速動作の期間中において、変速進行度PRGに応じて、それぞれしきい値α1およびα2より小さいしきい値β1およびβ2に向かって変更される。
【選択図】図5
Description
この発明の別の局面に従えば、上述のいずれかのハイブリッド駆動装置を備える車両である。
図1は、この発明の実施の形態に従うハイブリッド駆動装置1の概略構成図である。
このような高速段Hiから低速段Loへの変速動作における第2モータジェネレータ12の出力トルク制御について以下に説明する。まず、「変速制御トルク要求値」と一定のしきい値との比較(切替条件)に基づいて、「走行制御トルク要求値」と「変速制御トルク要求値」との間の切替えを行なう先行例について例示する。なお、以下では、「走行制御トルク要求値」が有効化されている制御モードを「パワーON制御」とも称し、「変速制御トルク要求値」が有効化されている制御モードを「パワーOFF制御」とも称する。
本実施の形態に従うハイブリッド駆動装置1では、変速動作の開始時に比較して、変速動作の開始後における走行制御トルク要求値#MG2TQ*の選択、すなわち「パワーON制御」の選択がより容易に行なわれるように、切替条件(ここでは、しきい値)を緩和する。
図6を参照して、高速段Hiから低速段Loへの変速動作における変速進行度PRGは、MG2回転数MRN2の大きさによって規定される。具体的には、MG2回転数MRN2が高速段回転数NHGであるときに変速進行度PRG=0%とされ、低速段回転数NLGであるときに変速進行度PRG=100%とされる。すなわち、変速進行度PRGは、低速段Loに応じた目標回転数に対するMG2回転数MRN2の到達度であり、高速段Hiから低速段Loへの変速過程の完了度合を意味する。
図7は、この発明の実施の形態に従う制御構造の要部を示す機能ブロック図である。なお、図7に示す制御構造は、図1に示す電子制御装置28,30,34が予め格納されたプログラムに従って各機能ブロックに対応する処理を連係して実行することで実現できる。
上述した本実施の形態に従う高速段Hiから低速段Loへの変速動作に係る処理手順をまとめると、以下のようになる。
上述した本実施の形態では、変速進行度PRGに対応付けてしきい値を変化させる構成について説明したが、変速進行度PRGに加えてMG2回転数MRN2の増加速度、もしくはMG2回転数MRN2の増加速度だけに応じて、しきい値を変更するようにしてもよい。
図10(a1)は、MG2回転数MRN2の時間的変化を示す。図10(b1)は、図10(a1)の場合に比較して、より大きな増加速度で変化するMG2回転数MRN2の時間的変化を示す。
