Description
本発明の他の目的は、変速機を持たないタイプのハイブリッドシステムを有する車両において、例えば、運転者による意識的なシフト操作以外の走行環境による走行規制制御が行われることを可能とするとともに、車両の再加速応答性が良好な制駆動力制御装置を提供することがである。
図1から図13を参照して、本発明の制駆動力制御装置の第1実施形態について説明する。
Tbなどが入力されており、必要に応じてバッテリ50の状態に関するデータを通信によりハイブリッド用電子制御ユニット70に出力する。なお、バッテリECU52では、バッテリ50を管理するために電流センサにより検出された充放電電流の積算値に基づいて残容量(SOC)も演算している。
まず、ステップS001にて、アクセル開度PAPと、車速(ペラシャフト回転数)の読み込みが行なわれる。
次に、ステップS002にて、ドライバーが要求するペラシャフトトルク(ドライブシャフトトルク)、即ち、ドライバー要求ペラシャフトトルク(ドライブシャフトトルク)が算出される。例えば、図2に示すようなマップが参照されて、上記ステップS001にて読み込まれたアクセル開度PAPと、車速(ペラシャフト回転数)に基づいて、ドライバー要求ペラシャフトトルク(駆動力(目標ペラトルク))が算出される。
次に、ステップS003にて、ドライバーが要求するパワー(ドライバー要求パワー)と、ドライバーが要求するエンジン回転数(ドライバー要求エンジン回転数)が算出される。
次に、ステップS004にて、ドライバーが要求する目標変速段(ドライバー要求目標変速段)が算出される。例えば、図4に示すようなマップが参照されて、上記ステップS001にて読み込まれたアクセル開度PAP及び車速(ペラシャフト回転数)と、上記ステップS002にて算出されたドライバー要求ペラシャフトトルクに基づいて、ドライバー要求目標変速段が決定される。
次に、ステップS005では、登降坂制御、コーナー制御、車間距離制御等の変速点制御の規制変速段が読み込まれる。例えば、登降坂制御が行われる場合、図11に示すようなマップが参照されて、規制変速段が決定される。図11は、道路勾配θに応じた目標変速段が記述されており、規制変速段は目標変速段よりも1段高速段側の変速段である。同様に、例えば、コーナー制御が行われる場合、図12に示すようなマップが参照されて、規制変速段が決定される。車間距離制御が行われる場合、図13に示すようなマップが参照されて、規制変速段が決定される。図12及び図13のそれぞれは、目標変速段を示しており、規制変速段は、目標変速段よりも1段高速段側の変速段である。
次に、ステップS006では、ドライバー要求目標変速段が上記ステップS005にて求められた変速点制御の規制変速段以上か否かが判定される。その判定の結果、肯定的に判定された場合には、ステップS007に進み、そうでない場合にはステップS008に進む。
ステップS007では、ドライバー要求目標変速段に変速点制御の規制変速段を反映させて、変速段の規制が実施される。このステップS007では、ドライバー要求ペラシャフトトルク(ドライブシャフトトルク)Tp*と、ドライバー要求エンジン回転数Ne*が変更される。
ステップS008では、エンジントルクTe*、MG1回転数Nm1*、目標MG1トルクTm1*、目標MG2トルクTm2*が算出される。以下に、その算出方法について詳細に説明する。
Tm1*=前回Tm1*+KP(Nm1*−Nm1)+KI∫(Nm1*−Nm1)dt (2)
Tm2min=(Win−Tm1*・Nm1)/Nm2 (4)
Tm2max=(Wout−Tm1*・Nm1)/Nm2 (5)
