Abstract
Description
要件B:MG31(走行用モータ)の駆動力が所定範囲内で安定していること。
要件D:外乱(走行以外の用途での電力ロス)が十分小さくなっていること。
完了SOC設定情報は、図7に示されるマップに限られず、適宜変更可能である。たとえば、予め実験等によって車両重量ごとに適した充電完了SOCを求めて、より複雑な完了SOC設定情報(非線形の変化や階段状の変化を含むマップ等)を作成し、HV−ECU51の記憶装置に格納してもよい。HV−ECU51は、完了SOC設定情報を参照することで、車両重量に対応する充電完了SOCを設定することができる。これにより、車両重量が変化しても、現在の車両重量に適した充電制御を行なうことが可能になる。
今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。
