Description
図1は、実施例1の制御装置が適用されたFFハイブリッド車両の全体システムを示す。以下、図1に基づいて、FFハイブリッド車両の全体システム構成を説明する。
図2は、実施例1のモータコントローラ83にて実行されるEV停車中のモータアイドル制御処理流れを示す(モータアイドル制御手段)。以下、EV停車中のモータアイドル制御処理構成をあらわす図2の各ステップについて説明する。
(a) Dレンジの選択
(b) EVモードの選択
(c) 車速<停車閾値
(d) ブレーキON
(e) アクセルOFF
(f) ATF油温<指定温度
(g) 異常判定していない
そして、これらの条件(a)〜(g)の全てが成立したとき、制御許可領域判定条件が成立と判断される。
以下、図2のフローチャートに基づき、モータアイドル制御処理作用を説明する。クリープカット条件を含む制御許可領域判定条件が成立し、CL2スタンバイ学習が完了していると、図2のフローチャートにおいて、ステップS1→ステップS2→ステップS3→ステップS4→ステップS5→ステップS6→ステップS7へと進む。ステップS2では、CL2スタンバイ学習が完了したか否かを判定する。ステップS3では、セカンダリ指示圧の下限値である第1セカンダリ下限圧Pmin1を設定する。ステップ4では、セカンダリプーリ6bへのセカンダリ圧Psecを制御するセカンダリ指示圧を、第2セカンダリ下限圧Pmin2に向かって低下させる制御指令が出力される。ステップS5では、車両の停車が確定したか否かを判定する。ステップS6では、セカンダリ指示圧の下限値である第2セカンダリ下限圧Pmin2を設定する。ステップS7では、セカンダリ指示圧が所定値以下になったか否かが判断され、セカンダリ指示圧>所定値と判断されている間は、ステップS7の判断が繰り返される。
まず、アイドル回転数の最適化及び低回転化を目指すモータアイドル制御の構想中、本発明車等から抽出された課題は、下記に列挙する通りである。
(1)CL2推定温度が高い領域では、低回転禁止すること。
(2)ハイ変速比での停車時は、低回転禁止すること(低回転中はメカによりロー変速比を固定すること)。
(3)平地以外では、低回転禁止すること。
(4)実ライン圧が出ていない場合は、低回転禁止すること。
(5)スタンバイ学習の影響を与えないこと。
(6)セレクト制御に影響を与えないこと。
(7)復帰時、油圧応答悪化による容量不足を生じないこと。
(8)停車中、油量収支が不足している領域では、オイルポンプ回転を上げること。
(1)CL2推定温度が所定温度以下の時、低回転化を許可する。
(2)停車時変速比が、所定変速比以上の時、低回転化を許可する。なお、低回転中は、バランス推力比を削ってセカンダリ下限圧を実現するので、メカによりロー変速比を固定することはできないが、無回転なのでストロークは無い。
(3)±数%以内は平地として、低回転化を許可する。
(4)低回転中は、実セカンダリ圧を監視し、セカンダリ下限圧に対して所定圧を下回ったら、低回転を即解除する。
(5)スタンバイ学習後(収束判定後)のみ第2モータアイドル回転数Nma2への低回転化を許可する。
(6)セレクト制御中は低回転化を禁止する。
(7)低回転中はトルクダウンを要求する。解除時も油圧復帰時間ディレイと復帰レートを温度軸で設定できるようにする。
(8)油温と指示圧に応じて、下限回転を要求する。
実施例1では、EVモードでの停車時、モータジェネレータ4によるクリープトルクを必要としないクリープカット条件が成立し、CL2スタンバイ学習が完了すると、モータジェネレータ4の回転数を、第1モータアイドル回転数Nma1より低い第2モータアイドル回転数Nma2まで下げる構成とした。即ち、通常制御での第1モータアイドル回転数Nma1から第2モータアイドル回転数Nma2に低下させることで、その差回転数によってモータアイドル制御中のモータ消費電力が抑えられる。このため、モータ電源である強電バッテリ21のバッテリ容量の低下が抑えられる。バッテリ容量の低下が抑えられると、横置きエンジン2によりモータジェネレータ4を駆動させて強電バッテリ21を充電するエンジン発電モードが選択される時間が、第1モータアイドル回転数Nma1による通常のモータアイドル制御時に比べて減少する。従って、EVモードでの停車中、モータジェネレータ4の消費電力が抑えられ、モード燃費が向上する。
次に、第2クラッチ5における第2クラッチ油圧指令値と実際に第2クラッチ5が発生する第2クラッチトルク容量との関係を学習補正する第2クラッチ学習補正制御処理(CL2スタンバイ学習)について説明する。上述したように、WSCモードでは、第2クラッチ5をスリップ制御するため、第2クラッチ油圧指令値に対して実際に発生する第2クラッチトルク容量との関係性(以下、第2クラッチトルク容量特性と記載する。)がずれていると、適正なトルクを駆動輪に伝達することができず、所望の動力性能を得ることができない。図5は第2クラッチ油圧指令値とモータトルク値との関係を表す特性図である。尚、モータトルク値の変化特性は、第2クラッチ5がトルク容量を持っているときの第2クラッチトルク容量の変化特性と一致するため、実質的に第2クラッチ油圧指令値と第2クラッチトルク容量との関係を表すものとして以下に述べる。図5中の(C)は指令値に対して実際に発生するトルク容量の関係を表し、図5中の(A)は初期設定の特性として低めの指令値で所望のトルク容量が発生できると認識している場合の特性、図5中の(B)は初期設定の特性として高めの指令値で所望のトルク容量が発生できると認識している場合の特性を表す。また、P0は実際のゼロ点における第2クラッチ指令油圧である。
〔式(1)〕
TCL2=μ・2N・D/2・(P・A−F)/i=μ・N・D・(P・A−F)/i
ここで、
μ:クラッチ摩擦係数
N:ドライブプレート枚数
D:第2クラッチ直径
P:第2クラッチ油圧
A:第2クラッチ油圧の受圧面積
F:リターンスプリング反力
i:遊星ギヤ比
である。
〔式(2)〕
F=P0・A
この式(2)を式(1)に代入すると、下記式(3)が得られる。
〔式(3)〕
P0=P−Tc/(μ・N・D・A/i)
〔式(4)〕
WSC時:Tmgwsc=Tfric_mg+TCL2+Tfric_op
〔式(5)〕
N時:Tmgn=Tfric_mg+Tfric_op
ここで、
Tfric_mg:モータフリクション
Tfric_op:機械式オイルポンプフリクション
である。
〔式(6)〕
TCL2=Tmgwsc−Tmgn
今、WSC時の第2クラッチ油圧指令値をPwscとすると、式(6)を式(3)に代入することで下記式(7)が得られる。
〔式(7)〕
P0=Pwsc−(Tmgwsc−Tmgn)/(μ・N・D・A/i)
