Description
図1は、モータ制御装置90の一例を示す構成図である。モータ制御装置90は、マイクロコントローラ1、ASIC2、ECU(Electronic Control Unit)3、アクセルセンサ30、及びブレーキセンサ31を有し、ハイブリッド車や電気自動車などの電動車両(以下、車両と表記)に搭載される。
次に車種パラメータ130及び特性マップデータ140について述べる。モータ50,51の駆動制御に適する回転数-トルクマップデータ及びトルク-電流マップデータは、車種ごとの仕様に応じて異なる。このため、CPU10及び演算部21は、車種パラメータ130に基づいて特性マップデータ140から、モータ制御装置90の搭載先の車種に対応する回転数-トルクマップデータ及びトルク-電流マップデータを取得して上記の演算処理に用いる。以下に車種パラメータ130がディファレンシャルギア52の減速比である場合の回転数-トルクマップデータ及びトルク-電流マップデータを例に挙げる。
図6は、CPU10の動作の一例を示すフローチャートである。以下に述べるステップSt2~St8は、モータ制御装置90の搭載先の車両の車種に応じたモータ50,51の駆動制御に関する演算処理の一例である。
