Description
図1を参照して、本発明の一実施形態に係る四輪駆動車の駆動装置の全体構成を説明する。図1は、本実施形態に係る駆動装置1の全体構成を示す模式図である。図1に示す駆動装置1は、前輪3LF,3RF及び後輪3LR,3RRを電動モータによって駆動する全輪駆動(AWD:All-Wheel Drive)の電気自動車の駆動装置である。
次に、本実施形態に係る駆動装置1の動作例を説明する。
まず、図3~図5を参照して、第1のモータ21及び第2のモータ23の使い分けの一例を説明する。図3は、第1のクラッチ機構41、第2のクラッチ機構35及び第3のクラッチ機構37の締結状態、並びに、第1のモータ21及び第2のモータ23の駆動状態を、車両の負荷状態ごとに示した説明図である。
次に、図7~図9を参照して、駆動モードの切り替えの一例を説明する。図7は、第1のクラッチ機構41、第2のクラッチ機構35、第3のクラッチ機構37、第4のクラッチ機構45及び第5のクラッチ機構47の締結状態、並びに、第1のモータ21及び第2のモータ23の駆動状態を、駆動モードごとに示した説明図である。
上述のとおり、本実施形態に係る駆動装置1は、左後輪3LRへ伝達する駆動力を調節可能な第4のクラッチ機構45と、右後輪3RRへ伝達する駆動力を調節可能な第5のクラッチ機構47とを備えている。このため、第4のクラッチ機構45及び第5のクラッチ機構47の締結力を調節(左右ベクタリング)することにより旋回性能を向上させることができる。また、第1のクラッチ機構41を開放状態として前輪側と後輪側とを切り離し、後輪側を第2のモータ23により駆動しつつ、前輪側を第1のモータ21により小出力で駆動させるかあるいは回生駆動することにより、左右ベクタリングとは別に、あるいは左右ベクタリングと併せて、前後輪の駆動力を調節することができる。したがって、車両のヨー回転の制御性が高められ、旋回性能を向上させることができる。
