Abstract
【解決手段】上位ECUは、電動機への出力要求に従ってトルク指令値T1を生成する(S100)。下位ECUは、電動機の動作状態に応じて、本来のトルク指令値T1を電動機の動作状態に応じて修正するためのトルク指令値T2を算出し(S210)、トルク指令値T1およびT2を総合して設定された最終トルク指令値Tf(S220)に従って電動機制御を行なう(S230)。上位ECUは、下位ECUからトルク指令値T2およびモータ状態量の伝送を受けて、モータ状態量から求めたトルク値実績Tj(S120)および、トルク指令値T2を反映して求めた最終トルク指令値Tf(S130)の比較により、電動機制御の異常検出を実行する(S150〜S170)。
【選択図】図5
Description
図1は、本発明の実施の形態に従う電動機の制御装置によって制御される電動機を搭載したハイブリッド車両の全体構成を説明するブロック図である。
図3を参照して、制御装置600は、振動抑制用トルク指令値算出部610と、加算点615と、電動機制御ブロック620とを含む。振動抑制用トルク指令値算出部610、加算点615および電動機制御ブロック620の各々は、制御装置600による制御演算処理により実現される機能ブロックに相当する。
(1)式中において、トルク定数Ktおよびd軸インダクタンスLdおよびq軸インダクタンスLqは、電動機530の定数であり、pは電動機530の極対数である。なお、(1)式に従った演算を逐次実行する他、これらのモータ定数に従ってモータ電流Id,Iqを引数としてトルク値実績Tjを算出するマップを予め用意してもよい。
とから求められるモータ電力Pmtならびに、回転速度Nmすなわち回転角速度ωにより、下記(2)式に従ってトルク値実績Tjを算出することも可能である。
さらに、上位ECUは、ステップS130により、下位ECUから受信した制振用トルク指令値T2に基づき最終トルク指令値Tfを算出する(Tf=T1+T2)。これにより、上位ECUにおいても、下位ECUにおいて付加したトルク指令値を反映して、下位ECUによる実際の電動機制御での最終トルク指令値Tfを取得することができる。
実施の形態1で説明したように制振用トルク指令値T2は下位ECUにより設定され、かつ電動機制御に反映される。したがって、下位ECUにおけるデータ異常(データ化け等)による制振用トルク指令値T2の設定異常についても、上位ECUにより異常検出可能な構成とすることが好ましい。実施の形態2では、このような異常検出について説明する。
