Abstract
Description
ECU100は、CPU(Central Processing Unit)と、メモリと、入出力ポート(いずれも図示せず)とを含んで構成される。ECU100は、各センサからの信号の入力ならびにメモリに記憶されたマップおよびプログラムに基づいて制御信号を出力するとともに、車両1が所望の状態となるように各機器を制御する。本実施の形態においてECU100により実行される主要な制御として、バッテリ60の劣化状態をインパネ80に表示させる処理が挙げられるが、詳細については後述する。
バッテリ60の容量維持率Qは、上記式(1)に従って算出された満充電容量Cをバッテリ60の満充電容量の初期値(たとえば、走行距離Dが基準距離Dbに達した時点での値)C0により除算することにより算出される(下記式(2)参照)。
図3に示すように、バッテリでは、一般に、その製造直後における劣化の進行度合いが最も大きい。仮に、容量維持率Qに基づいて、EV走行可能距離を算出するようにすると、EV走行可能距離は、車両の納品から直ぐに、著しく低下する。例えば、満充電時に、ユーザが乗車することを繰り返すと、前回の満充電時のEV走行可能距離と、今回の満充電時のEV走行可能距離との差が大きく、著しく満充電時のEV走行可能距離が低下したことに気づきやすい。その結果、ユーザは、車両1を新車として購入したにもかかわらず、直ぐにEV走行可能距離が著しく低下することから、バッテリ60が不良品ではないかなどの違和感を与えるおそれがある。
図4は、(100−容量維持率Q)%と、稼働SOCとの関係を示すグラフである。ECU100には、図4に示すような(100−容量維持率Q)%と、稼働SOCとの関係を示すデータが格納されている。このグラフにおいて、横軸は、(100−容量維持率Q)%を示し、縦軸は、バッテリ60のSOCを示す。
図5は、アイコン81の表示値と、(100−容量維持率Q)との関係を示すグラフである。このグラフの縦軸は、アイコン81の表示値を示し、横軸は、(100−容量維持率Q)を示す。なお、アイコン81の表示値とは、本実施の形態においては、図2に示すアイコン81の数である。ECU100には、図5に示すグラフに対応するデータが格納されている。
図7は、EV走行可能距離およびアイコン81の表示値を設定する制御フローを示すフロー図である。
