PROBLEM TO BE SOLVED: To provide an index that can offer more accurate determination regarding a utilization status of battery charging by a battery charger.SOLUTION: A utilization index IDX is calculated based on one or more parameters (the number of charges/the number of trips, total battery charger connection time/total vehicle stop time, total EV traveling distance/total HV traveling distance, total EV traveling time/total HV traveling time, total EV traveling distance/total traveling distance, total EV traveling time/total traveling time, and total charge amount/total fuel supply quantity) obtained based on a ratio of an EV traveling utilization level to an HV traveling utilization level or a total traveling utilization level, and the utilization index IDX is stored. Since the utilization index IDX is calculated such that as each parameter is larger, utilization of battery charging by a battery charger is performed more sufficiently. Accordingly, the utilization index IDX can be used as an index that offers more accurate determination regarding a utilization status of the battery charging. As a result, various processing to promote the battery charging can be executed more appropriately.SELECTED DRAWING: Figure 2 【課題】充電器によるバッテリの充電の利用状況をより適正に判断することができる指標を提供する。【解決手段】ＨＶ走行の利用度や走行の総利用度に対するＥＶ走行の利用度の比率に基づいて得られるパラメータ（充電回数／トリップ回数、充電器接続総時間／停車総時間、ＥＶ走行総距離／ＨＶ走行総距離、ＥＶ走行総時間／ＨＶ走行総時間、ＥＶ走行総距離／総走行距離、ＥＶ走行総時間／総走行時間、総充電量／総給油量）のうちの１つまたは複数に基づいて利用指標ＩＤＸを演算して記憶する。利用指標ＩＤＸは、各パラメータが大きいほど充電器によるバッテリの充電の利用が良好に行なわれているものとして演算されるから、バッテリの充電の利用状況をより適正に判断することができる指標となる。この結果、バッテリの充電を促す種々の処理をより適正に実行することができる。【選択図】図２
