(2)目的地までの走行ルートが充電に必要な充電時間とともに提示されていないため、算出された充電量が充電時間も勘案した妥当なものとなっているかどうかをユーザが判断できない。   (2) Since the travel route to the destination is not presented together with the charging time required for charging, the user cannot determine whether or not the calculated charging amount is reasonable considering the charging time.

(3)算出された充電量に対する微調整をドライバができないため、例えばルートから外れて少しだけ寄り道をする可能性がある場合等、ドライバの意思を簡単に充電量に反映させることができない。   (3) Since the driver cannot make fine adjustments to the calculated charge amount, the intention of the driver cannot be easily reflected in the charge amount, for example, when there is a possibility of deviating slightly from the route.

(4)走行ルートから外れた際の対処に関する記載がなく、ユーザが設定した目的地にたどり着けない可能性がある。   (4) There is no description about how to deal with when the vehicle deviates from the travel route, and there is a possibility that the destination set by the user cannot be reached.

Embodiment 1 FIG.
FIG. 1 shows a device configuration of a charge control device according to a first embodiment of the present invention. In FIG. 1, reference numeral 1 denotes own vehicle position specifying means for specifying the own vehicle position, 2 denotes registered place holding means for storing and holding a registered place of the own vehicle registered in advance, and 3 denotes own vehicle position specifying means 1. When the identified vehicle position is compared with the registered location held by the registered location holding means 2, and if it is determined that the vehicle location is not a registered location, the travel route from the vehicle location to the registered location is calculated. Travel route calculation means 4 for performing power amount calculation means 4 for calculating the amount of power required for the host vehicle to travel the travel route calculated by the travel route calculation means 3, and 5 for a power storage device mounted on the host vehicle. Charge amount management means for managing the charge amount (current charge amount, that is, remaining amount), 6 subtracts the charge amount managed by the charge amount management means 5 from the power amount calculated by the power amount calculation means 4 The minimum charge amount that should be charged at the charging facility Charge amount calculation means for calculating; 7 a charge time calculation means for calculating a time required for charging the charge amount calculated by the charge amount calculation means 6; 8 a display such as a liquid crystal screen; Charging information presenting means for presenting the user with the travel route calculated in 3, the charging amount calculated by the charging amount calculating means 6, and the charging time calculated by the charging time calculating means 7, 9 Is a charge amount fine adjustment means for the user to finely adjust the charge amount calculated by the charge amount calculation means 6 manually.

次に動作について説明する。本実施の形態に係る充電制御装置においては、上述したように、登録場所保持手段2には、自車両の登録場所のデータが予め入力されて保持されている。登録場所としては、自車両がユーザ個人の車両であれば、通常、自宅が登録されるが、これに限定されるものではなく、どの場所を登録場所とするかはユーザが自由に選択して適宜登録すればよい。このように登録場所保持手段2に自車両の登録場所のデータが保持されている状態において、登録場所以外の充電設備で充電する際には、まず、本実施の形態に係る充電制御装置は、自車位置特定手段1にて自車両の位置を特定する。自車位置を特定する手段としては、カーナビゲーション等に用いられているGPSを用いた手段が一般的だが、特にこれに限定する必要はなく、自車位置が特定できる手段であれば、いずれのものを自車位置特定手段1として用いてもよい。次に、走行ルート演算手段3では、自車位置特定手段1にて特定された自車両の位置に基づいて、現在の自車位置が登録場所保持手段2にて保持されている登録場所と同一かどうかを判定し、現在の自車位置が登録場所保持手段2に登録されている登録場所でないと判定した場合は、現在の自車位置から登録場所までの最適な走行ルートを探索し演算する。次に、電力量演算手段4では、走行ルート演算手段3で演算された走行ルートに従って自車両が登録場所まで走行するのに必要な電力量を演算する。この電力量の演算は、自車両の電費(=単位電力量当たりの走行距離)の仕様、あるいは、履歴があれば履歴、等を用いて演算するのが一般的ではあるが、他の情報(例えば、走行ルート上の勾配情報、季節によってはエアコンの使用予測電力量の情報、等)を用いてもよく、この限りでない。充電量管理手段5は、自車両に搭載されている蓄電装置の充電量(残量)を管理しており、現在の充電量(残量)を出力する。充電量演算手段6では、電力量演算手段4で演算された電力量から充電量管理手段5による現在の充電量を差し引いた電力量を、充電設備にて充電すべき充電量として、演算する。充電時間演算手段7では、充電量演算手段6で演算された充電量を充電するのに必要な時間を演算する。自宅以外の充電設備であれば、急速充電器であることが多く、また、充電速度も既知であるため、充電時間を演算することは難しくない。   Next, the operation will be described. In the charging control apparatus according to the present embodiment, as described above, the registration location data of the own vehicle is input and held in the registration location holding means 2 in advance. As the registration location, if the own vehicle is a user's personal vehicle, the home is usually registered. However, the registration location is not limited to this, and the user can freely select which location is the registration location. Register as appropriate. Thus, in the state where the registration location data of the own vehicle is held in the registration location holding means 2, when charging with a charging facility other than the registration location, first, the charging control device according to the present embodiment is: The own vehicle position is specified by the own vehicle position specifying means 1. As a means for specifying the own vehicle position, a means using the GPS used for car navigation or the like is generally used, but it is not particularly limited to this, and any means can be used as long as the own vehicle position can be specified. A thing may be used as the vehicle position specifying means 1. Next, in the travel route calculation means 3, the current own vehicle position is the same as the registered place held by the registered place holding means 2 based on the position of the own vehicle specified by the own vehicle position specifying means 1. If it is determined that the current vehicle position is not the registered location registered in the registered location holding means 2, the optimum travel route from the current vehicle location to the registered location is searched and calculated. . Next, the electric energy calculation means 4 calculates the electric energy necessary for the host vehicle to travel to the registered location according to the travel route calculated by the travel route calculation means 3. The calculation of the amount of electric power is generally performed using the specification of the power consumption of the own vehicle (= travel distance per unit electric energy) or the history if there is history, but other information ( For example, gradient information on the travel route, information on the predicted power consumption of the air conditioner depending on the season, etc.) may be used. The charge amount management means 5 manages the charge amount (remaining amount) of the power storage device mounted on the host vehicle, and outputs the current charge amount (remaining amount). The charge amount calculation means 6 calculates a power amount obtained by subtracting the current charge amount by the charge amount management means 5 from the power amount calculated by the power amount calculation means 4 as a charge amount to be charged by the charging facility. The charging time calculation means 7 calculates the time required to charge the charge amount calculated by the charge amount calculation means 6. If it is a charging facility other than home, it is often a quick charger and the charging speed is also known, so it is not difficult to calculate the charging time.

次に、充電情報提示手段8では、走行ルート演算手段3にて演算された走行ルート、充電量演算手段6にて演算された充電量、及び、充電時間演算手段7で演算された充電時間の3つをユーザに対し提示する。ユーザは、この充電情報提示手段8に提示された走行ルート、充電量、及び、充電時間に問題がなければ、決定ボタンを押し、これにより、演算された充電量がその充電設備にて充電する充電量として決定される。なお、ここでは、充電情報提示手段8に、走行ルート、充電量、及び、充電時間の3つを表示する例について述べたが、必ずしも3つ表示する必要はないが、このうちの、走行ルートと充電時間は表示することが望ましい。   Next, in the charging information presentation means 8, the travel route calculated by the travel route calculation means 3, the charge amount calculated by the charge amount calculation means 6, and the charge time calculated by the charge time calculation means 7 are displayed. Three are presented to the user. If there is no problem with the travel route, the charge amount, and the charge time presented to the charge information presenting means 8, the user presses the decision button, whereby the calculated charge amount is charged at the charging facility. It is determined as the amount of charge. In addition, although the example which displays a driving | running route, charge amount, and charging time on the charging information presentation means 8 was described here, it is not necessary to display three, but of these, a driving | running route It is desirable to display the charging time.

最後に、充電量微調整手段9の動作について説明する。充電設備にて充電する充電量としては、充電量演算手段6にて演算された充電量で基本的に問題ないが、当該充電量は、蓄電装置の劣化を抑制するために必要最低限の値であるため、例えば「時間的に余裕があるから、もう少しだけ充電量を増やしたい」とか、「演算された走行ルートから少し外れるが、コンビニに寄って帰りたいので、その分の充電量を増やしたい」とユーザが感じることは十分想定される。このようにユーザが感じた場合には、充電量微調整手段9で、充電量演算手段6で演算された充電量を微調整する(すなわち、充電量を増加させる)。微調整の方法としては、増加させたい充電量の数値をユーザがテンキー等により直接入力するか、あるいは、予め設定された増量の候補が複数個画面表示され、その中からユーザが選択して入力するようにしてもよい。また、充電量ではなく、充電時間を入力するようにしてもよい。また、これらを入力するためのテンキーや入力ボタンは、例えば、充電情報提示手段8のディスプレイを共有して画面表示するようにすればよく、あるいは、別個に押ボタンを設置しておいてもよいが、これらに限定されるものではない。このように充電量微調整手段9で充電量演算手段6で演算された充電量を微調整することにより、ユーザの意思を簡単に充電量へ反映させることができる。なお、充電量または充電時間を増加させる例について述べたが、充電量微調整手段9では、充電量または充電時間を減少させることも可能な構成となっている。   Finally, the operation of the charge amount fine adjustment means 9 will be described. There is basically no problem with the amount of charge calculated by the amount-of-charge calculating means 6 as the amount of charge to be charged by the charging facility, but the amount of charge is a minimum value necessary for suppressing deterioration of the power storage device. So, for example, “I want to increase the amount of charge a little because I have time,” or “I am slightly off the calculated driving route, but I want to return to the convenience store, so increase the amount of charge for that amount. It is assumed that the user feels “I want to”. When the user feels like this, the charge amount fine adjustment means 9 finely adjusts the charge amount calculated by the charge amount calculation means 6 (that is, increases the charge amount). As a fine adjustment method, the user directly inputs the numerical value of the amount of charge to be increased with the numeric keypad or the like, or a plurality of preset increase candidates are displayed on the screen, and the user selects and inputs them. You may make it do. Moreover, you may make it input charging time instead of charge amount. Further, the numeric keypad and the input button for inputting these may be displayed on the screen by sharing the display of the charging information presenting means 8, or a separate push button may be provided. However, it is not limited to these. In this way, by finely adjusting the charge amount calculated by the charge amount calculation means 6 by the charge amount fine adjustment means 9, the intention of the user can be easily reflected in the charge amount. In addition, although the example which increases charge amount or charge time was described, the charge amount fine adjustment means 9 becomes a structure which can also reduce charge amount or charge time.

本実施の形態によれば、以上のような構成とすることで、走行ルート演算手段3が自車位置が登録場所以外であると判断したときに登録場所までの走行ルートを演算し、電力量演算手段4が当該走行ルートを走行するのに必要な電力量を求め、充電量演算手段6が当該電力量と充電量管理手段5による現在の充電量との差分を充電すべき充電量として求めるとともに、充電時間演算手段7が当該充電量の充電にかかる時間を求めて、登録場所以外の充電設備で充電する際の充電量及び/又は充電時間を提示するようにしたので、毎回、目的地や出発時刻等を入力する必要がなく、自動的に充電量が算出されるため、ユーザの利便性を損なうことなく、バッテリの劣化を抑制することができる。   According to the present embodiment, with the configuration as described above, when the travel route calculation means 3 determines that the vehicle position is other than the registered location, the travel route to the registered location is calculated, and the electric energy The calculation means 4 obtains the amount of power required for traveling along the travel route, and the charge amount calculation means 6 obtains the difference between the power amount and the current charge amount by the charge amount management means 5 as the charge amount to be charged. At the same time, the charging time calculation means 7 obtains the time required for charging the charging amount and presents the charging amount and / or charging time when charging with a charging facility other than the registered place. Since the amount of charge is automatically calculated without having to input the departure time or the departure time, it is possible to suppress the deterioration of the battery without impairing the convenience for the user.

また、充電情報提示手段8により走行ルートとともに充電時間を提示することで、演算された充電量が、充電時間も考慮した妥当なものであるかの充電量の妥当性をドライバが判断することができる。   Further, by presenting the charging time together with the travel route by the charging information presenting means 8, the driver can determine the validity of the charging amount as to whether the calculated charging amount is appropriate considering the charging time. it can.

また、充電量微調整手段9によりユーザが充電量を微調整できるため、時間に余裕がある場合、あるいは、寄り道する可能性がある場合は、そのユーザの意思を充電量へ簡単に反映させることができる。   Further, since the user can finely adjust the charge amount by the charge amount fine adjustment means 9, if there is a time margin or there is a possibility of detouring, the user's intention is easily reflected in the charge amount. Can do.

実施の形態2.
上述の実施の形態1では、自車両が自宅等の登録場所以外の充電設備にて充電する場合の充電制御について説明したが、実施の形態2では、充電設備での充電を完了した後、登録場所保持手段2にて保持している登録場所へ走行している際の充電制御について説明する。
Embodiment 2. FIG.
In the above-described first embodiment, the charging control in the case where the host vehicle charges at a charging facility other than the registration location such as home is described. However, in the second embodiment, after the charging at the charging facility is completed, the registration is performed. The charging control when traveling to the registered place held by the place holding means 2 will be described.

図2に、本実施の形態に係る充電制御装置の装置構成を示す。図2において、21は現在の自車位置と走行ルートとをユーザに対して表示する走行状況表示手段、22は自車位置が走行ルートから外れた際に警報を発生する警報発生手段、23は、電力量演算手段4で演算された電力量と充電量管理手段5で管理している充電量とを基に、自車両が登録場所まで到達できるか判定する到達判定手段である。なお、他の構成(符号1〜5の構成)については実施の形態1と同じであるため、ここでは、その説明を省略する。   FIG. 2 shows a device configuration of the charge control device according to the present embodiment. In FIG. 2, 21 is a driving status display means for displaying the current vehicle position and the driving route to the user, 22 is an alarm generating means for generating an alarm when the vehicle position deviates from the driving route, and 23 is Based on the amount of power calculated by the power amount calculation means 4 and the charge amount managed by the charge amount management means 5, it is an arrival determination means for determining whether the host vehicle can reach the registered location. Other configurations (configurations of reference numerals 1 to 5) are the same as those in the first embodiment, and thus the description thereof is omitted here.

次に動作について説明する。充電設備での充電を完了後、自車両が演算された走行ルートに沿って走行している間は通常のカーナビゲーションと同様、走行状況表示手段21に自車位置と走行ルートとが表示されているが、警報発生手段22にて、自車位置が走行ルートから外れたか否かを周期的に判定し、外れたと判定した場合には、警報を発生する。警報は警報音、あるいは、音声メッセージによる警報が一般的だが、自車両が走行ルートから外れたことをユーザに知らせる目的であればこの限りでない。また、警報発生手段22にて自車両が走行ルートから外れたと判定された際は、走行状況表示手段21は、走行状況表示手段21に表示されている自車位置と走行ルートの表示色を変更する。例えば、自車位置と走行ルートの表示色を通常時は青などの寒色とし、走行ルートから外れた場合は、ユーザの注意を促せるように、黄色や赤色等の暖色の表示色に変更する。このようにすることによってユーザが警報音、あるいは、音声による警報を聞き逃した場合でも、走行ルートから外れたことを確実に認識できる。また、自車位置と走行ルートの表示を点滅させてもよく、あるいは、表示色を充電量管理手段5にて管理している蓄電装置の充電量に応じた表示色としてもよい。すなわち、充電量の緊急度合いのレベルを予め複数個に分けて設定し、各レベルごとに表示色を設定しておき、現在の充電量に応じて、その表示色で表示するようにしてもよい(例えば、レベル0(通常時):青、レベル1:緑、レベル2:黄緑、レベル3:黄、レベル4:オレンジ、レベル5(要充電時):赤のように、設定しておく。)。このようにすることで、ユーザが走行ルートを外れた際の緊急度合いを把握することができる。   Next, the operation will be described. After the charging at the charging facility is completed, while the vehicle is traveling along the calculated travel route, the vehicle status and the travel route are displayed on the travel status display means 21 as in the normal car navigation. However, the alarm generation means 22 periodically determines whether or not the vehicle position has deviated from the travel route. If it is determined that the vehicle has deviated, an alarm is generated. The alarm is generally an alarm sound or an alarm using a voice message, but this is not limited as long as it is intended to notify the user that the vehicle is off the driving route. When the alarm generation means 22 determines that the host vehicle has deviated from the travel route, the travel status display means 21 changes the display position of the host vehicle and the travel route displayed on the travel status display means 21. To do. For example, the display color of the vehicle position and the travel route is normally a cold color such as blue, and when it is off the travel route, it is changed to a warm display color such as yellow or red so as to alert the user . In this way, even when the user misses the warning sound or the warning by voice, it can be surely recognized that the user has deviated from the traveling route. Further, the display of the vehicle position and the travel route may be blinked, or the display color may be a display color corresponding to the charge amount of the power storage device managed by the charge amount management means 5. That is, the level of the urgency level of the charge amount may be divided and set in advance, a display color may be set for each level, and the display color may be displayed according to the current charge amount. (For example, level 0 (normal time): blue, level 1: green, level 2: yellow-green, level 3: yellow, level 4: orange, level 5 (during charging): red) .) By doing in this way, it is possible to grasp the degree of urgency when the user deviates from the travel route.

次に、ユーザが上記警報を無視して走行ルートから大きく外れた場合の説明をする。ユーザが警報音、あるいは、音声メッセージによる警報と、走行状況表示手段21の変化に気付かず、走行ルートから大きく外れてしまったと警報発生手段22で判断した場合は(すなわち、自車位置と走行ルートとの間の最短距離が予め設定した閾値よりも大きくなった場合は)、自車両の現在の進行方向等を考慮し、走行ルート演算手段3により、現在の自車位置から登録場所までの新たな走行ルートを再演算するとともに、電力量演算手段4によりその走行ルートを自車両が走行するのに必要な電力量を再演算する。到達判定手段23では、再演算された電力量と充電管理手段5にて管理されている蓄電装置の充電量との比較を行い、前記電力量が前記充電量以下の場合は再演算された走行ルートにて登録場所への到達が可能と判断し、再演算された走行ルートにて自車両の誘導を開始する。逆に、到達判定手段23にて前記電力量が前記充電量よりも大きい場合は、再演算した走行ルートでの登録場所への到達は不可能と判断し、最寄りの充電設備を探索し、その充電設備までの走行ルートを演算後、探索した充電設備への誘導を開始する。なお、この際には、ユーザに対し、充電量不足につき、探索した充電設備への誘導を開始する旨を、文字メッセージにより画面表示するか、あるいは、音声メッセージを発生させるかにより、通知する。   Next, the case where the user disregards the warning and greatly deviates from the travel route will be described. When the user is not aware of the warning sound or the warning by voice message and the change of the driving condition display means 21, and the warning generating means 22 determines that the user greatly deviates from the driving route (that is, the vehicle position and the driving route) If the shortest distance between the vehicle and the vehicle is greater than a preset threshold value), the travel route calculation means 3 takes into account a new position from the current vehicle position to the registered location in consideration of the current traveling direction of the vehicle. The power amount calculation means 4 recalculates the power amount necessary for the host vehicle to travel along the travel route. The arrival determination means 23 compares the recalculated power amount with the charge amount of the power storage device managed by the charge management means 5, and when the power amount is less than or equal to the charge amount, the recalculated travel time It is determined that it is possible to reach the registered place on the route, and guidance of the host vehicle is started on the recalculated travel route. Conversely, if the amount of power is greater than the amount of charge in the arrival determination means 23, it is determined that it is impossible to reach the registered location on the recalculated travel route, and the nearest charging facility is searched for. After calculating the travel route to the charging facility, the guidance to the searched charging facility is started. At this time, the user is notified of the shortage of the charge amount, whether the guidance to the searched charging facility is to be started by displaying the text message or generating a voice message.

なお、上記の登録場所への走行ルートと必要な電力量の再演算は、複数回実施してもよく、その場合は、複数回再演算した後、登録場所へ到達できる走行ルートがないと判断した場合に、最寄りの充電設備の探索と誘導を行ってもよい。   It should be noted that the above recalculation of the travel route to the registered place and the required electric energy may be carried out a plurality of times, in which case it is determined that there is no travel route that can reach the registered place after recalculation several times. In this case, the nearest charging facility may be searched and guided.

It becomes possible to do.

また、走行ルートから外れた際に、自車位置か、あるいは、走行ルートの少なくとも一方の表示色を変更することで、音声等による警報を聞き逃した場合でも、ユーザが走行ルートから外れたことを確認することができる。   In addition, when the vehicle is deviated from the driving route, the user has deviated from the driving route even if he / she missed the warning by voice, etc. Can be confirmed.

また、自車位置、走行ルートの表示色は蓄電装置の充電量のレベルに基づいた表示色とすることで、ユーザが走行ルートを外れた際の緊急度合いを把握できる。   Further, the display color of the vehicle position and the travel route is set to the display color based on the level of the charge amount of the power storage device, whereby the degree of urgency when the user leaves the travel route can be grasped.

また、自車両が走行ルートから外れた場合でも、現在の充電量で自宅等の登録場所への到達が可能と判断した場合には、自車両の走行状況に基づき、新たな走行ルートを再演算し提示することで、ユーザが元の走行ルートに戻る煩わしさを抑制できる。   In addition, even if the vehicle deviates from the travel route, if it is determined that it is possible to reach a registered location such as home with the current charge amount, a new travel route is recalculated based on the travel status of the vehicle. By presenting it, the troublesomeness of the user returning to the original travel route can be suppressed.

また、自車両が走行ルートから外れてしまい、かつ、自宅等の登録場所へ到達できないと判断した場合は、登録場所以外の他の充電設備への案内を開始することで、登録場所へ到達できなくなる状況を確実に防止できる。   In addition, if it is determined that the vehicle has deviated from the driving route and cannot reach the registered location such as home, the registration location can be reached by starting guidance to other charging facilities other than the registered location. The situation that disappears can be surely prevented.
