It can prevent more appropriately that a use lower limit amount is changed. As a result, the electrically driven vehicle 1 ⁇ / b> B can ensure the appropriateness of the use of the first battery 12 in that it is possible to suitably prevent the usage lower limit amount from being changed inappropriately. In addition, about the usage minimum amount after a change, it can set similarly to the case of the electric drive type vehicle 1A also in the electric drive type vehicle 1B.
- the electrically driven vehicle 1C is substantially the same as the electrically driven vehicle 1A except that the electrically driven vehicle 1C includes a vehicle side ECU 50C instead of the vehicle side ECU 50A.
- the vehicle-side ECU 50C is substantially the same as the vehicle-side ECU 50A except that the diagnosis unit and the management unit are further realized as described below. For this reason, the illustration of the electrically driven vehicle 1C is omitted. Similar changes can be applied to the electrically driven vehicle 1B described in the second embodiment, for example.
- the diagnosis unit is further realized to diagnose the power generation possible amount of the power generation device 11.
- the diagnosis means is based on the remaining amount of fuel in the power generation device 11, the type of fuel, and the operating conditions of the power generation device 11 that operates such as when operating at the rated output or when operating at the maximum output, It implement
- FIG. The diagnosis means is implemented so as to diagnose the amount of power that can be generated by the power generation device 11 when it is diagnosed that the power generation device 11 can generate power.
- the management unit when the diagnosis unit determines that the power generation device 11 can generate power and diagnoses the amount of electric power that can be generated, the management unit further determines the first electric power according to the magnitude of the electric power that can be generated.

- the management means can be implemented to correct the lower limit amount of use so that the lower limit amount of use becomes larger as the amount of power that can be generated is larger.
- step S3 the vehicle-side ECU 50C diagnoses the amount of electric power that can be generated (step S9) and corrects the lower limit amount of use according to the amount of electric power that can be generated (step S10). Subsequently, the vehicle-side ECU 50C determines whether or not the battery charge amount has fallen below the corrected use lower limit amount (step S11B). If the determination is negative, step S11B is repeatedly executed until the determination is positive, and if the determination is affirmative, the process proceeds to step S12.
- the use lower limit amount can be corrected so that the use lower limit amount becomes smaller as the amount of power that can be generated is larger.
- the use start time of the second battery 30 can be delayed as compared with the case where the use lower limit amount is the use lower limit amount before correction (that is, the use lower limit amount after change). For this reason, in this case, since the first battery 12 can be used more effectively, the cruising distance of the vehicle can be further increased as compared with the case of the electrically driven vehicle 1A.
- the lower limit amount of use can be corrected so that the lower limit amount of use becomes larger as the amount of power that can be generated is larger.
- the use start time of the power generator 11 can be advanced compared to the case where the lower limit amount is the lower limit amount before correction (that is, the lower limit amount after use). Therefore, in this case, the use of the first battery 12 can be more restricted, so that the first battery 12 can be prevented from being overused. As a result, compared with the case of the electrically driven vehicle 1A. In addition, it is possible to further suppress the life reduction of the first battery 12.
- the electrically driven vehicle 1 ⁇ / b> C has the first battery 12 according to the amount of electric power that can actually compensate for the shortage of the battery of the first battery 12 compared to the electrically driven vehicle 1 ⁇ / b> A.

Abstract
Description
これに対して例えば特許文献1では、第1のバッテリを車載するとともに、発電ユニットまたは第2のバッテリを脱着可能に搭載する電気自動車が開示されている。特許文献1が開示する電気自動車は、電気スタンドの近くや自宅周辺で電気自動車を乗り回す場合には、第2のバッテリを搭載する一方で、遠くまでドライブする場合には、発電ユニットを搭載することとしている。
このほか車載したバッテリの充電を行うことが可能な発電機を備える点で、本発明と関連性があると考えられる技術が例えば特許文献2で、複数のバッテリを備える点で本発明と関連性があると考えられる技術が例えば特許文献3から5までで開示されている。
この点、電気駆動式車両が発電装置を脱着可能に搭載する場合には、発電装置搭載時にバッテリ充電量が減少した場合、ユーザに対して充電を促す警告を出力する代わりに、発電装置を利用してバッテリを充電することが考えられる。すなわち、発電装置を搭載している場合と搭載していない場合との間で同様の設定値でバッテリ充電量を管理することが考えられる。
しかしながら、発電装置を搭載している場合には、発電装置を搭載していない場合とは異なり、退避走行や充電スタンドまでの走行が可能と見込まれるバッテリ充電量を必ずしも確保しておく必要がない。
さらに発電装置を利用してバッテリを充電する場合、発電装置の運転開始時期は、バッテリの利用についてその適切性に影響を及ぼすことになる。すなわち、例えば発電装置の運転がバッテリ残量に照らして相対的に早く開始される場合には、それだけバッテリが有効に利用されないことになる。また、例えば逆に発電装置の運転がバッテリ残量に照らして相対的に遅く開始される場合には、それだけバッテリが酷使されることになる。
また車両側ECU50Aには電動モータ13などの各種の制御対象が電気的に接続されているほか、キースイッチ21や、発電スイッチ22や、アクセル開度センサ61や、ブレーキスイッチ62や、搭載状態の発電装置11を検知することで、発電装置11の搭載、非搭載を検知可能な状態検知手段である第1の搭載検知センサ63などの各種のセンサ・スイッチ類が電気的に接続されている。
さらに車両側ECU50Aには、バッテリ充電量を検出するために第1のバッテリ12が電気的に接続されている。この点、電気駆動式車両1Aでは、第1のバッテリ12のバッテリ充電量に対して使用下限量が予め設定されている。
発電装置11が発電可能であるか否かを診断するにあたり、診断手段は具体的には発電装置11の発電可能状態について診断するように実現される。
この点、診断手段は例えば発電装置11が搭載されているか否かを判断することで、発電装置11の発電可能状態について診断するよう実現することができる。
また診断手段は例えば、さらに発電装置11の搭載状態が正規の状態であるか否かを検出するために設けられた図示しないインターロック装置(例えば発電装置11の固定確認装置や、発電装置11の格納スペースに対して設けられた扉のロック確認装置)が正規の状態を検出しているか否か、発電装置11の燃料が十分(所定量以上)であるか否か、発電装置11の電気的接続状態に異常がないか否か、発電装置11の機械的な接続状態に異常がないか否か、発電装置11に故障などの異常がないか否か、またはこれらの判断内容を適宜組み合わせて判断することで、発電装置11の発電可能状態について診断するよう実現できる。
具体的には診断手段は、上述した各判断内容を組み合わせて判断した結果、発電装置11が搭載されており、インターロック装置が正規の状態を検出しており、発電装置11の燃料が所定量以上であり、発電装置11の電気的および機械的な接続状態に異常がなく、且つ発電装置11に異常がないと判断した場合に、発電装置11が発電可能であると判断するように実現される。
管理手段は具体的には、診断手段が、発電装置11が発電可能であると判断した場合に、第1のバッテリ12の充電量管理として使用下限量を変更するように実現される。この点、予め設定されている使用下限量(以下、設定使用下限量と称す)は、具体的には発電装置11が発電可能でない場合に対応させて設定されており、さらに具体的には退避走行や充電スタンドまでの走行が可能と見込まれるバッテリ充電量に設定されている。
一方、使用下限量を変更するにあたり、管理手段は具体的には例えば、発電装置11が発電可能でない場合よりも使用下限量を低く変更するように実現することができる。また管理手段は例えば、発電装置11が発電可能でない場合よりも使用下限量を高く変更するように実現することができる。
一方、車両側ECU50Aでは、例えば発電装置11が発電可能であり、且つバッテリ充電量が使用下限量を下回った場合に、発電装置11に対する運転要求を出力するための出力制御手段が機能的に実現される。この点、この場合の使用下限量は具体的には変更後の使用下限量となる。
この点、電気駆動式車両1Aでは、発電装置11が発電可能であると判断した場合に、例えば発電装置11が発電可能でない場合よりも使用下限量を低く変更することができる。そしてこの場合、電気駆動式車両1Aは、低く変更された変更後の使用下限量をバッテリ充電量が下回るまでの間、第1のバッテリ12を利用することから、使用下限量が設定使用下限量である場合と比較して、発電装置11の運転開始時期を遅らせることができる。このためこの場合には、第1のバッテリ12をより有効に利用できるようになる。したがってこの場合には、さらに具体的には第1のバッテリ12をより有効に利用できるようになる分、車両の航続距離を実質的に拡大することができる。
このため電気駆動式車両1Aは、発電装置11を脱着可能に搭載する場合に、第1のバッテリ12の利用について適切性を確保できる。
そしてこれにより電気駆動式車両1Aは、使用下限量が不適切に変更されてしまうことを好適に防止できる点でも、第1のバッテリ12の利用について適切性を確保できる。
また変更後の使用下限量については、例えば車両の使用履歴を記録する記録手段を備えるとともに、記録手段が記録した使用履歴に基づいて設定することができる。この場合には、車両の使用傾向に応じたより適切な効果が得られるようになる点で好適である。この点、この場合には、変更後の使用下限量の初期値を例えば電気駆動式車両1Aへの要求性能に応じて予め設定しておくほか、使用履歴が当初存在しないことを考慮して、変更後の使用下限量の初期値を例えば設定使用下限量に予め設定しておいてもよい。
また変更後の使用下限量については、例えば変更後の使用下限量の大きさを調節、或いは段階的に選択することが可能な操作手段を備えるとともに、操作手段に対して行われた操作に基づき設定することができる。この場合には、ユーザが希望する効果が得られるようになる点で好適である。
第2の搭載検知センサ64は、搭載状態の第2のバッテリ30を検知することで、第2のバッテリ30の搭載、非搭載を検知可能な状態検知手段として、車両本体10に設けられている。この点、第1の搭載検知センサ63は第2のバッテリ30の搭載、非搭載を検知しないように、第2の搭載検知センサ64は発電装置11の搭載、非搭載を検知しないようにそれぞれ設けられている。
車両側ECU50Bは、診断手段および管理手段がさらに以下に示すように実現される点と、以下に示す電源切替手段がさらに機能的に実現される点と、バッテリ充電量を検出するために第2のバッテリ30がさらに電気的に接続される点と、第2の搭載検知センサ64がさらに電気的に接続されている点以外、車両側ECU50Aと実質的に同一のものとなっている。
第2のバッテリ30が利用可能であるか否かを診断するにあたり、診断手段は具体的には第2のバッテリ30の利用可能状態について診断するよう実現される。
この点、診断手段は例えば、第2のバッテリ30が搭載されているか否かを判断することで、第2のバッテリ30の利用可能状態について診断するように実現することができる。
また診断手段は例えば、さらに第2のバッテリ30の搭載状態が正規の状態であるか否かを検出するために設けられた図示しないインターロック装置(例えば第2のバッテリ30の固定確認装置や、第2のバッテリ30の格納スペースに対して設けられた扉のロック確認装置)が正規の状態を検出しているか否か、第2のバッテリ30のバッテリ充電量が十分(所定量以上)であるか否か、第2のバッテリ30の電気的な接続状態が正常であるか否か、第2のバッテリ30に故障などの異常がないか否か、またはこれらの判断内容を適宜組み合わせて判断することで、第2のバッテリ30の利用可能状態について診断するよう実現できる。
具体的には診断手段は、上述した各判断内容を組み合わせて判断した結果、第2のバッテリ30が搭載されており、インターロック装置が正規の状態を検出しており、第2のバッテリ30のバッテリ充電量が所定量以上であり、第2のバッテリ30の電気的な接続状態に異常がなく、且つ第2のバッテリ30に異常がない場合に、第2のバッテリ30が利用可能であると判断するように実現される。
管理手段は具体的には、診断手段が第2のバッテリ30が利用可能であると判断した場合に、第1のバッテリ12の充電量管理として使用下限量を変更するよう実現される。この点、電気駆動式車両1Bでは、設定使用下限量が、発電装置11が発電可能でなく、且つ第2のバッテリ30が利用可能でない場合に対応させて設定された使用下限量となっている。
一方、使用下限量を変更するにあたり、管理手段は具体的には例えば、第2のバッテリ30が利用可能でない場合よりも使用下限量を低く変更するように実現することができる。また管理手段は例えば、第2のバッテリ30が利用可能でない場合よりも使用下限量を高く変更するように実現することができる。
電源切替手段は、第2のバッテリ30が利用可能であり、且つ第1のバッテリ12のバッテリ充電量が使用下限量を下回った場合に、第1のバッテリ12から第2のバッテリ30に電源を切り替えるための制御を行うように実現される。この点、この場合の使用下限量は具体的には変更後の使用下限量となる。
また電気駆動式車両1Bでは、発電装置11に加えて第2のバッテリ30を脱着可能に搭載するにあたり、発電装置11と互換搭載可能に構成された第2のバッテリ30を脱着可能に搭載している。このため電気駆動式車両1Bでは、発電装置11に加えて第2のバッテリ30を脱着可能に搭載するにあたり、車両本体10に対して大幅な変更を加えることなく、第2のバッテリ30を脱着可能に搭載できる点で、コスト的に有利な構成とすることができる。
この点、電気駆動式車両1Bでは第2のバッテリ30が利用可能である、と判断した場合に、第2のバッテリ30が利用可能でない場合よりも使用下限量を低く変更することができる。そしてこの場合には、使用下限量が設定使用下限量である場合と比較して、第2のバッテリ30の利用開始時期を遅らせることができる。このためこの場合には、第1のバッテリ12をより有効に利用できるようになる分、車両の航続距離を実質的に拡大ことができる。
このため電気駆動式車両1Bは、電気駆動式車両1Aと比較して、さらに第2のバッテリを脱着可能に搭載した場合でも、第1のバッテリ12の利用について適切性を確保できる。
そしてこれにより電気駆動式車両1Bは、使用下限量が不適切に変更されてしまうことを好適に防止できる点でも、第1のバッテリ12の利用について適切性を確保できる。
なお、変更後の使用下限量については、電気駆動式車両1Bでも電気駆動式車両1Aの場合と同様に設定することができる。
この点、診断手段は具体的には、発電装置11の燃料の残量、燃料の種類、および定格出力で運転する場合や最大出力で運転する場合など運転する発電装置11の運転条件に基づき、発電装置11の発電可能電力量について診断するように実現される。
また診断手段は、発電装置11が発電可能である、と診断した場合に、発電装置11の発電可能電力量について診断するように実現される。
具体的には管理手段は、発電可能電力量の大きさに応じて、使用下限量を補正することで、第1のバッテリ12の充電量管理を補正するように実現される。この点、この場合の使用下限量は具体的には変更後の使用下限量となる。
一方、使用下限量を変更するにあたり、管理手段は例えば、発電可能電力量が大きいほど、使用下限量が小さくなるように使用下限量を補正するよう実現することができる。また管理手段は例えば、発電可能電力量が大きいほど、使用下限量が大きくなるように使用下限量を補正するよう実現することができる。
この点、電気駆動式車両1Cでは、例えば発電可能電力量が大きいほど、使用下限量が小さくなるように使用下限量を補正することができる。そしてこの場合には、使用下限量が補正前の使用下限量(すなわち変更後の使用下限量)である場合と比較して、第2のバッテリ30の利用開始時期を遅らせることができる。このためこの場合には、第1のバッテリ12をより有効に利用できるようになる分、電気駆動式車両1Aの場合と比較して、さらに車両の航続距離を実質的に拡大ことができる。
このため電気駆動式車両1Cは、電気駆動式車両1Aと比較して、さらに第1のバッテリ12のバッテリ不足を実際に補うことが可能な電力量の大きさに応じて、第1のバッテリ12をより適切に利用できるようになる点で、第1のバッテリ12の利用についてより好適に適切性を確保できる。
例えば上述した実施例では、第1のバッテリ12の充電量管理を行うにあたって、使用下限量を変更する場合について説明した。
しかしながら本発明においては必ずしもこれに限られず、第1のバッテリの充電量管理を行うにあたり、管理手段は例えば第1のバッテリに対して充電上限量を設定するとともに、充電上限量を変更してもよい。
この場合には、例えば充電上限量を相対的に低く変更することで、発電装置を利用する機会を増大させることができることから、これにより第1のバッテリの寿命低下を抑制することができ、また充電上限量を相対的に高く変更することで、第1のバッテリをより有効に利用することができる。
この場合にも、管理手段は例えば、第2のバッテリのバッテリ充電量が大きいほど、使用下限量が小さくなるように使用下限量を補正することや、第2のバッテリのバッテリ充電量が大きいほど、使用下限量が大きくなるように使用下限量を補正することができる。
しかしながら本発明においては必ずしもこれに限られず、電気駆動式車両は、例えば発電装置および第2のバッテリを同時搭載可能なように車両本体に脱着可能に搭載してもよい。また電気駆動式車両は、例えば発電装置または第2のバッテリのうち、少なくともいずれかを同時搭載可能なように車両本体に脱着可能に複数搭載してもよい。
この場合、診断手段は例えば複数の発電装置が発電可能であるか否か、および複数の第2のバッテリが利用可能であるか否かを全体的に診断することができ、管理手段は例えばこれら複数の診断結果に応じて、第1のバッテリの充電量管理を行うようにすることができる。
これにより、複数の発電装置および複数の第2のバッテリのうち、いずれか1つの診断結果のみに応じて、第1のバッテリの充電量管理を行う場合と比較して、第1のバッテリをより適切に利用できるようになる。またこの場合に、複数の発電装置の各発電可能電力量の大きさ、および複数の第2のバッテリの各バッテリ充電量の大きさに応じて、使用下限量をさらに補正することで、第1のバッテリをさらに適切に利用することもできるようになる。
