Abstract
バッテリ15の温度を検出する温度センサ20と、温度センサ20が所定の温度以上、または所定の温度を超えるバッテリ15の温度を検出したときには、減速時の回生発電中に、エンジン10と電動機13とを接続するように制御するハイブリッドECU18と、を有し、ハイブリッドECU18は、ハイブリッド自動車1の減速時のギア段数に応じて所定の温度を設定するようにする。
【選択図】図4
Description
u5<u4<u3<u2、d5<d4<d3<d2
であり、第二の大小関係が
d5<u5、d4<u4、d3<u3、d2<u2
である。
クラッチ12を断状態とする回生と、クラッチ12を接状態とする回生とを切り換える際のバッテリ15の温度の閾値を、ギア段数によって変えることにより、各ギア段数に最適なバッテリ15の温度条件によって、クラッチ12の断接制御を実施することができる。これにより、冗長なクラッチ12の断接制御を無くし、バッテリ15のSOCが低下することを抑えつつバッテリ15の温度上昇を抑えることができる。
図3のフローチャートの説明において、「以上」は、「超える」とし、「未満」は、「以下」とするなど、判定の境界値については様々に変更してもよい。
