Description
図1は、本実施例1のモータで車両を駆動するモータ制御システムの構成例である。
上記式(1)において、IDはd軸電流、IQはq軸電流、αはモータ極対数、Aは磁石磁束、Bはd軸とq軸とのインダクタンス差であり、モータによって決まる定数である。
実施例2は、実施例1と同様な効果を得るもう一つの例であり、特にセンサの出力値に含まれる誤差によってはDC電圧の上昇が収まらない場合を考慮した例である。
実施例3は実施例1や実施例2の処理と共に実施する車両制御に関する例である。コンタクタ202の接続が解放されたとき、実施例1や実施例2を実施すると、今まで回生制御により発生していた制動トルクがほぼ無くなる。これによりコンタクタ202の接続が開放された直後から車両の速度の落ち方が遅くなるため、車両の運転手はブレーキのかかり方が弱くなった違和感を抱くおそれがある。
