Abstract
【解決手段】ECU60は、蓄電装置Bの温度およびSOCに基づいて、蓄電装置Bの出力可能電力Pmaxを推定する(ステップS40)。また、ECU60は、エンジン4の始動に必要な電力に基づいてしきい電力Pthを算出する(ステップS50)。そして、ECU60は、出力可能電力Pmaxがしきい電力Pthを下回っていると判定すると(ステップS60でYES)、昇圧コンバータ10の昇圧率を規定値以下に制限するように昇圧コンバータ10を制御する(ステップS70)。
【選択図】図5
Description
好ましくは、制御装置は、蓄電装置の出力電力がしきい値よりも小さいとき、電圧昇圧率を規定値以下に制限するように昇圧装置を制御する。
図1は、この発明の実施の形態1による負荷駆動装置が搭載される車両の一例として示されるハイブリッド車両の全体ブロック図である。図1を参照して、このハイブリッド車両100は、車輪2と、動力分割機構3と、エンジン4と、モータジェネレータMG1,MG2とを備える。また、ハイブリッド車両100は、蓄電装置Bと、昇圧コンバータ10と、インバータ20,30と、コンデンサC1,C2と、電源ラインPL1,PL2と、接地ラインSLと、電子制御装置(Electronic Control Unit;以下「ECU」とも称する。)60と、電圧センサ70,72,74と、電流センサ76,78,80と、温度センサ82,84とをさらに備える。
Pg=Pb−Pc−Pg−Pm−Lc−Lg−Lm …(1)
ここで、Pbは蓄電装置Bから出力される電力、PcはコンデンサC1,C2にチャージされる電力、PgはモータジェネレータMG1の実行電力、PmはモータジェネレータMG2の実行電力、Lcは昇圧コンバータ10における損失、Lgはインバータ20における損失、Lmはインバータ30における損失を表わす。
実施の形態1では、出力可能電力Pmaxがしきい電力Pthを下回っていると、昇圧コンバータ10の昇圧率を規定値以下に制限するように昇圧コンバータ10を制御するものとしたが、実施の形態2では、出力可能電力Pmaxがしきい電力Pthを下回っていると、昇圧コンバータ10を停止させる。
図8は、実施の形態3におけるエンジン始動時の昇圧コンバータ10の制御を説明するためのフローチャートである。図8を参照して、このフローチャートに示される処理は、図5に示したフローチャートにおいて、ステップS30〜S60に代えてステップS110を含む。すなわち、ステップS20において蓄電装置Bの温度TBが取得されると、エンジン始動制御部62は、その取得した温度TBが予め設定されたしきい値よりも低いか否かを判定する(ステップS110)。このしきい値は、蓄電装置Bの出力が大きく低下する適当な温度に設定することができる。
図9は、実施の形態4におけるエンジン始動時の昇圧コンバータ10の制御を説明するためのフローチャートである。図9を参照して、このフローチャートに示される処理は、図5に示したフローチャートにおいて、ステップS20〜S60に代えてステップS210,S220を含む。すなわち、ステップS10においてエンジン4の始動が要求されていると判定されると、エンジン始動制御部62は、温度センサ84からエンジン4の温度TEを取得する(ステップS210)。
