The fuel consumption information C is information representing the amount of fuel consumed per unit mileage. The electric power cost information E is information representing the amount of electric power consumed per unit mileage. The fuel consumption information C and the electricity cost information E may be calculated from the driving results of only the traveling route R by the user, or calculated from the traveling results of all or part of the routes by the user so far. It may be a thing.

発電効果演算部１５は、発電走行履歴記憶部１３に記憶された発電走行履歴と、燃費電費情報取得部１４で取得された燃費情報Ｃ及び電費情報Ｅとに基づいて、以下の２つの発電効果に関する演算を行うことができる。この演算は、典型的には、走行ルートＲの車両走行が終了した時に実施される。 The power generation effect calculation unit 15 has the following two power generation effects based on the power generation running history stored in the power generation running history storage unit 13 and the fuel consumption information C and the power cost information E acquired by the fuel consumption electricity cost information acquisition unit 14. Can perform operations related to. This calculation is typically performed when the vehicle on the travel route R has finished traveling.

まず第１の演算として、発電効果演算部１５は、複数の走行区間Ｌの区間発電電力量ｗに基づいて、複数の走行区間Ｌのそれぞれについて区間発電電力量ｗの平均値（以下「平均発電電力Ｐ」という）を演算する。平均発電電力Ｐは、該当する走行区間Ｌにおける区間発電電力量ｗを、距離で平均化した値であってもよいし、時間で平均化した値であってもよい。図３の例では、走行ルートＲが図２に示したように５つの走行区間Ｌ１〜Ｌ５に分割されており、その５つの走行区間Ｌ１〜Ｌ５について平均発電電力Ｐ１〜Ｐ５がそれぞれ算出されている。 First, as a first calculation, the power generation effect calculation unit 15 is based on the section power generation amount w of the plurality of traveling sections L, and the average value of the section power generation amount w for each of the plurality of traveling sections L (hereinafter, “average power generation”). Power P ") is calculated. The average power generation power P may be a value obtained by averaging the section power generation amount w in the corresponding traveling section L by a distance, or a value averaged by time. In the example of FIG. 3, the traveling route R is divided into five traveling sections L1 to L5 as shown in FIG. 2, and the average power generation powers P1 to P5 are calculated for each of the five traveling sections L1 to L5. There is.

発電効果演算部１５は、算出した平均発電電力Ｐの大きさに応じて、走行区間Ｌに割り当てる色を予め定義している。例えば、図４に示すように、平均発電電力Ｐが取り得る最小値「０」から最大値「Ｐｍａｘ」までの範囲が４段階に区分され、各区分に色Ｃ１〜Ｃ４がそれぞれ割り当てられている。この各区分に割り当てられる色Ｃ１〜Ｃ４は、例えば、平均発電電力Ｐが大きいほど明るい色となるように設定することができる。 The power generation effect calculation unit 15 defines in advance a color to be assigned to the traveling section L according to the size of the calculated average generated power P. For example, as shown in FIG. 4, the range from the minimum value "0" to the maximum value "Pmax" that the average generated power P can take is divided into four stages, and colors C1 to C4 are assigned to each division. .. The colors C1 to C4 assigned to each of the categories can be set so that, for example, the larger the average generated power P, the brighter the color.

図３及び図４の例では、平均発電電力Ｐ１の走行区間Ｌ１には、色Ｃ２が割り当てられ、平均発電電力Ｐ２の走行区間Ｌ２には、色Ｃ３が割り当てられ、平均発電電力Ｐ３の走行区間Ｌ３には、色Ｃ４が割り当てられ、平均発電電力Ｐ４の走行区間Ｌ４には、色Ｃ３が割り当てられ、平均発電電力Ｐ５の走行区間Ｌ５には、色Ｃ１が割り当てられることになる。 In the examples of FIGS. 3 and 4, the traveling section L1 of the average generated power P1 is assigned the color C2, the traveling section L2 of the average generated power P2 is assigned the color C3, and the traveling section of the average generated power P3. The color C4 is assigned to L3, the color C3 is assigned to the traveling section L4 of the average generated power P4, and the color C1 is assigned to the traveling section L5 of the average generated power P5.

次に第２の演算として、発電効果演算部１５は、走行ルートＲの総発電電力量Ｗ、燃費情報Ｃ、及び電費情報Ｅに基づいて、ソーラーパネル１１の発電電力によって車両が得た効果に関する情報（以下「実績情報」という）を演算する。この実績情報とは、発電電力で節約できた電力量、この節約できた電力量によって走行できた距離（拡張された電力走行距離）、発電電力で節約できた燃料量、及びこの節約できた燃料量によって走行できた距離（拡張された燃料走行距離）などである。これらの実績情報は、次のように演算される。なお、αは、電力−燃料変換率である。 Next, as a second calculation, the power generation effect calculation unit 15 relates to the effect obtained by the vehicle by the generated power of the solar panel 11 based on the total generated power amount W, the fuel consumption information C, and the power cost information E of the traveling route R. Calculates information (hereinafter referred to as "actual information"). This performance information is the amount of power saved by the generated power, the distance traveled by this saved power amount (extended power mileage), the amount of fuel saved by the generated power, and the saved fuel. It is the distance that can be traveled depending on the amount (extended fuel mileage). These performance information are calculated as follows. In addition, α is a power-fuel conversion rate.

・節約できた電力量［ｋＷｈ］＝Ｗ［ｋＷｈ］
・拡張された電力走行距離［ｋｍ］＝Ｗ［ｋＷｈ］×Ｅ［ｋｍ/ｋＷｈ］
・節約できた燃料量［Ｌ］＝Ｗ［ｋＷｈ］×α［Ｌ／ｋＷｈ］
・拡張された燃料走行距離［ｋｍ］＝Ｗ［ｋＷｈ］×Ｃ［ｋｍ/Ｌ］×α［Ｌ/ｋＷｈ］ -The amount of power saved [kWh] = W [kWh]
-Extended power mileage [km] = W [kWh] x E [km / kWh]
-The amount of fuel saved [L] = W [kWh] x α [L / kWh]
-Extended fuel mileage [km] = W [kWh] x C [km / L] x α [L / kWh]

表示制御部１６は、発電効果演算部１５における演算によって得られた発電効果を、所定の画面（図示しないナビゲーション装置のモニタ、メーターパネルなどのデバイス、及びヘッドアップディスプレイなど）に表示することが可能な手段である。 The display control unit 16 can display the power generation effect obtained by the calculation in the power generation effect calculation unit 15 on a predetermined screen (a monitor of a navigation device, a device such as an instrument panel, a head-up display, etc., which is not shown). Means.

より具体的には、図５に示すように、表示制御部１６は、出発地（ＳＴＡＲＴ）から目的地（ＧＯＡＬ）までの走行ルートＲを、複数の走行区間Ｌ１〜Ｌ５に割り当てられた色Ｃを用いて色分けして画面に表示する。さらに、表示制御部１６は、走行ルートＲによる走行距離及び走行時間に加えて、実績情報として節約できた電力量と節約できた電力走行距離とを画面に表示する。 More specifically, as shown in FIG. 5, the display control unit 16 assigns the travel route R from the departure point (START) to the destination (GOAL) to the colors C assigned to the plurality of travel sections L1 to L5. Color-coded using and displayed on the screen. Further, the display control unit 16 displays on the screen the amount of electric power saved as the actual information and the saved electric power mileage in addition to the mileage and the traveling time according to the traveling route R.

なお、節約できた電力量と節約できた燃料量とは、同時に画面表示しても構わないし、いずれか一方を画面表示しても構わない。また、節約できた電力走行距離と節約できた燃料走行距離とについても、同時に画面表示しても構わないし、いずれか一方を画面表示しても構わない。どのように画面表示するかは、車両のタイプ（例えば、ガソリン車なのか電気自動車なのかなど）によって予め設定されていてもよいし、ユーザーが好みで設定できるようにしてもよい。また、実績情報と一緒に表示する他の情報は、走行ルートＲによる走行距離及び走行時間以外であってもよい。 The amount of electric power saved and the amount of fuel saved may be displayed on the screen at the same time, or one of them may be displayed on the screen. Further, the saved electric power mileage and the saved fuel mileage may be displayed on the screen at the same time, or one of them may be displayed on the screen. How to display the screen may be preset depending on the type of vehicle (for example, whether it is a gasoline vehicle or an electric vehicle), or may be set by the user as desired. Further, the other information to be displayed together with the actual information may be other than the mileage and the mileage according to the mileage route R.

［本実施形態における作用・効果］

Therefore, the user can easily grasp the effect actually obtained by the vehicle based on the power generated by the solar panel. In addition, the user can use the power generation effect grasped this time as a reference when traveling in the vicinity of the traveling route R next time (for example, where is a section or area where power can be generated well).

［変形例］
上述した表示制御部１６による発電効果の画面表示は、走行ルートＲの車両走行が終わった後に、すなわち走行ルートＲの総発電電力量Ｗ及び全走行区間Ｌの区間発電電力量ｗの情報が全て取得できた後に、実行するように説明した。しかし、表示制御部１６による発電効果の画面表示は、画面表示に必要な情報が取得できた走行途中の段階で、その都度実行してもよい。 [Modification example]
The screen display of the power generation effect by the display control unit 16 described above includes all the information of the total power generation amount W of the travel route R and the section power generation amount w of the entire travel section L after the vehicle travel of the travel route R is completed.
