Description

車載情報機器及びサーバIn-vehicle information equipment and server
　本発明は、車両に電力を充電可能な充電スポットを検索可能な車載情報機器、及び、それと通信可能なサーバに関するものである。 The present invention relates to an in-vehicle information device capable of searching for a charging spot capable of charging electric power to a vehicle, and a server capable of communicating with the vehicle information device.
　近年、電気自動車やプラグインハイブリッド車など、走行に電力を用いる車両（以下単に「車両」と呼ぶ）を充電する充電スポットのインフラ化が進められている。それに伴い、複数の充電スポットの中から、車両側にとって適切な充電スポットを検索する技術が様々に提案されている（例えば、特許文献１参照）。 In recent years, infrastructure for charging spots for charging vehicles that use electric power for traveling (hereinafter simply referred to as “vehicles”) such as electric vehicles and plug-in hybrid vehicles has been promoted. Along with this, various techniques for searching for a charging spot appropriate for the vehicle side from among a plurality of charging spots have been proposed (see, for example, Patent Document 1).
　一方、家庭用電力などに関する電力系統の分野においては、太陽光エネルギーなどの再生可能エネルギーから得られる不安定な発電電力に対して、電力需給のバランスをとる電力送配電網、すなわちスマートグリッド網が提案されている。このスマートグリッド網によれば省エネルギー化が実現可能となることから、近年、スマートグリッド網についても様々な技術が提案されている（例えば、特許文献２参照）。 On the other hand, in the field of power systems related to household power, power transmission and distribution networks that balance power supply and demand, that is, smart grid networks, against unstable generated power obtained from renewable energy such as solar energy.

　上述したように、充電スポットのインフラ化が進められているが、一部の給油所や自動車販売所などにしか設けられていないのが現状である。しかも、充電スポットは都市部に偏っており、都市郊外では、充電スポットの数が少ない状態にある。そのため、車両に電力を充電することが可能なスポットの数を早急に増やすことが求められている。 As mentioned above, charging spots are being built as an infrastructure, but they are currently provided only at some gas stations and car sales offices. Moreover, the charging spots are biased toward urban areas, and the number of charging spots is small in the suburbs of the city. For this reason, it is required to quickly increase the number of spots where the vehicle can be charged with electric power.
　一方、スマートグリッド網においては、発電電力が余剰となることがあり、その余剰電力を有効利用できる余地があった。 On the other hand, in the smart grid network, the generated power may become surplus, and there is room for effective use of the surplus power.
　そこで、本発明は、上記のような問題点を鑑みてなされたものであり、車両に電力を充電するスポットを増やすことが可能な技術を提供することを目的とする。 Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of increasing spots for charging power to a vehicle.
　本発明に係る車載情報機器は、車両に電力を充電可能な充電スポットを検索可能な車載情報機器であって、充電スポットは、スマートグリッド網に組み込まれたスマートメータを備え、充電スポットには、車両に電力を充電する設備を備えた一般家庭が含まれる。車載情報機器は、スマートメータからスマートグリッド網を介して集約された、各充電スポットの電力需給バランス情報を含む所定の充電スポット情報に基づいて検索を行う。 An in-vehicle information device according to the present invention is an in-vehicle information device capable of searching for a charging spot capable of charging electric power to a vehicle, and the charging spot includes a smart meter incorporated in a smart grid network. This includes general households equipped with facilities for charging vehicles. The in-vehicle information device performs a search based on predetermined charging spot information including power supply / demand balance information of each charging spot collected from the smart meter via the smart grid network.
　本発明によれば、充電スポット情報に基づいて、一般家庭を含む充電スポットを検索する。したがって、ユーザは、電力に余裕がある一般家庭から充電を受けることができるので、車両に電力を充電することが可能なスポットを増やすことができる。 According to the present invention, a charging spot including a general home is searched based on the charging spot information. Therefore, since the user can be charged from a general household with sufficient power, the number of spots where the vehicle can be charged with power can be increased.

The search unit 57 searches the charging spot 1 and the registered charging spot based on the charging spot information including the power source information and the registered charging spot information including the power source information. The possibility that the matching charging spot 1 and the registered charging spot can be acquired can be increased.
　また、本実施の形態によれば、通信部５２は、充電スポット１が車両７に充電する電力について決済を行うのに必要な決済情報を事前に送信する。これにより、車両７のユーザは、充電を行う場で支払い手続きを行わなくて済み、決済を簡単に行うことができる。 Further, according to the present embodiment, the communication unit 52 transmits in advance payment information necessary for making a payment for the power charged by the charging spot 1 to the vehicle 7. Thereby, the user of the vehicle 7 does not need to perform a payment procedure at the place of charging, and can easily make a payment.
　また、本実施の形態によれば、通信部５２は、入力部５１にて予約操作が行われた充電スポット１を示す予約情報を送信する。このような構成によれば、中央サーバ３が、車載情報機器５から予約情報を受信した以降に、当該予約情報が示す充電スポット１については充電スポット情報を他の車載情報機器５に送信しないようにすることができる。よって、他の車載情報機器５のユーザは、確実に空いている充電スポット１の中から所望の充電スポット１の検索（図６のステップＳ２５～Ｓ３２の検索）を行うことができる。 Further, according to the present embodiment, the communication unit 52 transmits the reservation information indicating the charging spot 1 for which the reservation operation has been performed by the input unit 51. According to such a configuration, after the central server 3 receives the reservation information from the in-vehicle information device 5, the charging spot information indicated by the reservation information is not transmitted to the other in-vehicle information device 5. Can be. Therefore, the user of the other in-vehicle information device 5 can search the desired charging spot 1 from the charging spots 1 that are vacant (search in steps S25 to S32 in FIG. 6).
　なお、以上の説明では、車載情報機器５の検索部５７が充電スポット情報に基づいて充電スポット１を検索する構成について説明したが、これに限ったものではない。例えば、中央サーバ３（制御部３３）が同様の検索を行い、その検索結果を車載情報機器５に送信するものであってもよい。 In addition, in the above description, although the search part 57 of the vehicle-mounted information apparatus 5 demonstrated the structure which searches the charging spot 1 based on charging spot information, it is not restricted to this.

For example, when the in-vehicle information device 5 is configured to include an audio output unit (not shown) capable of outputting audio, the audio output unit is used as a notification unit. That is, the voice output unit may output the warning information by voice.
　＜図６のステップＳ２５～Ｓ３２の検索についての変形例＞
　上述したステップＳ２８では、検索部５７は、移動時間が所定の閾値以下である充電スポット１を取得することについて説明した。しかしこれに限ったものではなく、検索部５７は、充電完了までにかかる所要時間（すなわち、充電器区別情報が示す充電速度と充電しようとする電力量とから算出される充電時間と、上述の移動時間との合計時間）が所定の閾値以下である充電スポット１を取得するものであってもよい。あるいは、検索部５７は、当該所要時間を現在時刻に加えて得られる充電完了予定時刻が、所定の時刻以内となる充電スポット１を取得するものであってもよい。 <Modified Example of Search in Steps S25 to S32 of FIG. 6>
In step S28 described above, the search unit 57 has explained that the charging spot 1 whose travel time is equal to or less than a predetermined threshold is acquired. However, the search unit 57 is not limited to this, and the search unit 57 takes the time required to complete charging (that is, the charging time calculated from the charging speed indicated by the charger identification information and the amount of power to be charged) You may acquire the charging spot 1 whose total time (movement time) is below a predetermined threshold value. Alternatively, the search unit 57 may acquire the charging spot 1 in which the scheduled charging completion time obtained by adding the required time to the current time is within a predetermined time.
　また、上述したステップＳ３０では、検索部５７は、価格情報により示される価格が所定の閾値以下である充電スポット１を取得することについて説明した。しかしこれに限ったものではなく、検索部５７は、位置情報が示す現在位置から、各充電スポット１まで移動するのに消費する消費電力と単位電力あたりの価格とに基づいて移動費用を求めるとともに、上述の価格情報が示す価格と充電しようとする電力量とに基づいて充電費用を求める。そして、検索部５７は、移動費用と充電費用との合計が所定の閾値以下である充電スポット１を取得するものであってもよい。また、検索時に目的地への経路が設定されていた場合には、上述の消費電力の代わりに、当該経路から外れて各充電スポット１まで移動するのに消費する消費電力を用いてもよい。 Also, in step S30 described above, the search unit 57 has explained that the charging spot 1 whose price indicated by the price information is equal to or less than a predetermined threshold is obtained. However, the present invention is not limited to this, and the search unit 57 calculates the travel cost based on the power consumption and the price per unit power consumed to move from the current position indicated by the position information to each charging spot 1. The charging cost is determined based on the price indicated by the price information and the amount of power to be charged. And the search part 57 may acquire the charging spot 1 whose sum of a movement expense and a charge expense is below a predetermined threshold value. Further, when a route to the destination is set at the time of the search, the power consumption consumed to move to each charging spot 1 outside the route may be used instead of the above power consumption.
　また、検索部５７は、余剰電力、距離及び時間、所要コスト、電力出所という項目のうち複数項目に基づいて適切な充電スポット１を検索する場合には、距離及び時間、所要コスト、電力出所に対して予め設定された優先順位に基づいて重み付けを行った上で検索を行ってもよい。 Further, when searching for an appropriate charging spot 1 based on a plurality of items among the items of surplus power, distance and time, required cost, and power source, the search unit 57 sets the distance, time, required cost, and power source. Alternatively, the search may be performed after weighting based on a preset priority order.
　＜図６のステップＳ３６及びＳ３７の予約についての変形例＞
　上述したステップＳ３６では、入力部５１が、充電スポット１に対する予約操作を受け付け、ステップＳ３７にて通信部５２が、予約操作が行われた充電スポット１を示す予約情報を送信することについて説明した。 <Modification of Reservation in Steps S36 and S37 in FIG. 6>
In step S36 described above, it has been described that the input unit 51 receives a reservation operation for the charging spot 1, and the communication unit 52 transmits reservation information indicating the charging spot 1 in which the reservation operation is performed in step S37.
　しかしこれに限ったものではなく、ステップＳ３５にて入力部５１は、充電開始予定時刻（現在時刻に上述の移動時間を加えた時刻、あるいはそれに少し余裕を持たせた時刻）、及び、充電予定電力量の入力操作を受け付けてもよい。そして、ステップＳ３６にて入力部５１が、上述の予約操作だけでなく、充電開始予定時刻及び充電予定電力量を受け付けた場合に、ステップＳ３７にて通信部５２が、予約情報とこれらの情報を送信するように構成してもよい。このように構成された場合には、予約をより適切に行うことができる。なお、充電開始予定時刻は、車両７のユーザが計算するのではなく、車載情報機器５が自動的に計算するように構成されてもよい。 However, the present invention is not limited to this. In step S35, the input unit 51 causes the charging start scheduled time (the time obtained by adding the above travel time to the current time, or a time with a little margin) and the charging schedule. An electric power amount input operation may be accepted. In step S36, when the input unit 51 receives not only the above-described reservation operation but also the scheduled charging start time and the scheduled charging power amount, the communication unit 52 sets the reservation information and these information in step S37. You may comprise so that it may transmit. In such a configuration, it is possible to make a reservation more appropriately. Note that the scheduled charging start time may not be calculated by the user of the vehicle 7 but may be automatically calculated by the in-vehicle information device 5.
　なお、本発明は、その発明の範囲内において、実施の形態を適宜、変形、省略することが可能である。 In the present invention, the embodiments can be appropriately modified or omitted within the scope of the invention.
