[ハイブリッド自動車の概要]
実施形態1に係る支援システムが搭載される自動車は、エンジン及びモータを動力源とするハイブリッド自動車であって、エンジンを運転状態で走行するエンジン走行とエンジンを停止した状態で走行するEV走行とが可能である。ハイブリッド自動車は、例えば、外部充電によって外部電源から充電可能、もしくは外部機器への外部給電可能なプラグインハイブリッド自動車(PHEV,PHV)であるが、プラグインハイブリッド自動車に限定されるものではない。
実施形態1に係る支援システム1Aは、EV走行の継続を支援するシステムであって、図1に示すように、EV優先モードを選択するためのEV優先モード選択装置10、駆動用バッテリの充電率を検出する充電率検出装置12、ブレーキブースタ14の負圧を検出する負圧検出装置16、ユーザの要求出力を検出する要求出力検出装置18、表示制御装置20、及びEV優先モードが選択された場合に、表示制御装置20からの指示により、一列に並んだ複数のセグメントSG1~SG3を表示する表示装置22を備えている。
図1に示すように、表示制御装置20は、充電点灯数決定部36、負圧点灯数決定部38、出力点灯数決定部40、及び点灯数指示部42を有している。
図3に示すように、実施形態1に係る支援システム1Aでは、EV優先モード選択装置10によってEV優先モードが選択(EV優先モードON)される(ステップS11:Yes)と、表示制御装置20からの指示により、表示装置22に一列に並んだ複数のセグメントSG1~SG3を表示する(ステップS12)。
実施形態1に係る支援システム1Aによれば、EV優先モードが選択された場合に、充電点灯数、負圧点灯数、又は出力点灯数のうち、最も少ない数のセグメントSG1~SG3を点灯するので、ユーザはセグメント点灯数(消灯数)を見ながら急激なアクセルペダル操作を避けて、ブレーキペダル操作よりも回生ブレーキ操作を優先することで、EV走行の継続を図ることができる(EV走行の継続支援)。
[支援システムの構成]
実施形態2に係る支援システム1B(図1参照)では、EV優先モードが選択された場合であって、EV走行が可能な場合に、表示装置22は、表示制御装置20からの指示により、EV表示EGを点灯する一方、EV走行が不能な場合に、表示制御装置20からの指示により、EV表示EGを消灯する。図2に示すように、EV表示EGは、例えば、「EV」の文字を縁取ったものであり、EV表示EGを点灯した場合にEVの文字を塗りつぶして光るように構成される。また、実施形態2に係る支援システム1Bは、EV優先モードモードが選択された場合であって、EV走行が可能な場合に、表示装置22は、表示制御装置20からの指示により、「EV走行中」の文字を表示する一方、EV走行が不能な場合に、表示制御装置20からの指示により、「待機中」の文字を表示してもよい。また、実施形態2に係る支援システム1Bは、EV優先モードモードが選択された場合であって、EV走行が可能な場合に、表示装置22は、表示制御装置20からの指示により、一列に並んだ複数のセグメントSG1~SG3の点灯色を一の点灯色(例えば、緑色)とする一方、EV走行が不能な場合に、表示制御装置20からの指示により、一列に並んだ複数のセグメントSG1~SG3の点灯色を他の一の点灯色(例えば、橙色)としてもよい。他の構成は、実施形態1に係る支援システム1Aと同じである。

実施形態2に係る支援システム1Bによれば、EV表示EGの点灯によりEV走行が可能であることをユーザに認識させ、EV表示EGの消灯によりEV走行が不能であること(エンジン走行をすること)をユーザに認識させることができる。また、EV表示EGの消灯により、エンジン走行からEV走行への復帰のためにエンジンにより発電された電気が駆動用バッテリに充電されていること、及び、回生ブレーキによって駆動用バッテリが充電されていることをユーザに認識させることができる。これにより、エンジン走行からEV走行に復帰するために、ユーザは急激なアクセルペダル操作を避けて、ブレーキペダル操作よりも回生ブレーキ操作を優先するように促すことができる。また、エンジン走行からEV走行に復帰するとEV表示EGが消灯から点灯に移行するので、ユーザはエンジン走行からEV走行に復帰するタイミングを視覚的に認識することができる。
[支援システムの構成]

図6に示すように、実施形態3に係る支援システム1Cでは、チャージモード選択装置44によってチャージモードが選択(チャージモードON)される(ステップA31:Yes)と、表示制御装置20からの指示により、表示装置22に一列に並んだ複数のセグメントSG1~SG3を表示する(ステップS32:Yes)。
実施形態3に係る支援システム1Cによれば、チャージモードが選択された場合に、充電点灯数のセグメントSG1~SG3を点灯するので、駆動用バッテリの充電率をユーザに視覚的に認識させることができる。
[支援システムの構成]
図7に示すように、実施形態4に係る支援システム1D(図5参照)では、複数のセグメントSG1~SG4は、左右に一列に並んだ4つのセグメントSG1~SG4によって構成され、駆動用バッテリの充電率が予め定めた満充電率以上の場合に点灯する満充電表示用のセグメントSG4を含む。満充電率は、満充電とされる充電率であり、最大充電率以下であって、左右に並んだ4つのセグメントSG1~SG4のうち左側から3つのセグメントSG1~SG3に充電率が割り当てられる場合に、少なくとも3つ目のセグメントSG3に割り当てられる最低充電率以上の充電率が設定される。満充電表示用のセグメントSG4は、左右に一列に並んだ4つのセグメントSG1~SG4で構成される場合に、右側から1つ目のセグメントSG4である。他の構成については、実施形態1から3に係る支援システム1A,1B,1Cのいずれかの構成と同じである。
実施形態4に係る支援システム1Dでは、例えば、チャージモード選択装置44によってチャージモードが選択され、エンジンの運転によって充電率検出装置12で検出された駆動用バッテリの充電率が満充電以上となった場合に、表示制御装置20からの指示により、満充電表示用のセグメントSG4が点灯する。
