There are cases. In view of this, it has been proposed that a plurality of power supply areas be installed so that power can be supplied at various locations on the way of the moving vehicle. For example, Patent Document 1 discloses an intermittent power supply type electric vehicle system.

上記特許文献１の構成によれば、充放電回路を利用して電気車両の蓄電器に給電を行うことができる。しかし、特許文献１の構成では、充放電回路は電気車両に設けられて電気車両が走行運行中での一時停車中に充放電を行っている。このように、短時間の停止中に充放電を行う場合は、送電の切替時間が短くなる。そして、車両への給電は数ｋＷの大電力を送電する必要があり、送電の切替スピードを早くすると、例えば系統電源から電力を供給する場合には電力損失が大きくなるため、安定した電力供給が困難となることがある。   According to the configuration of Patent Document 1, power can be supplied to the electric vehicle storage device using the charge / discharge circuit. However, in the configuration of Patent Document 1, the charging / discharging circuit is provided in the electric vehicle, and charging / discharging is performed while the electric vehicle is temporarily stopped while traveling. Thus, when charging / discharging is performed during a short stop, the switching time of power transmission is shortened. Power supply to the vehicle needs to transmit a large amount of power of several kW, and if the switching speed of power transmission is increased, for example, when power is supplied from the system power supply, power loss increases, so stable power supply is possible. It can be difficult.

また、上記特許文献２の構成によれば、非接触給電を行うことができる。しかし、特許文献２の構成では、上記と同様に短時間の停車中に非接触給電を行うと、同様に系統電源の電力損失が大きくなるため、安定した電力供給が困難となることがある。   Moreover, according to the structure of the said patent document 2, non-contact electric power feeding can be performed. However, in the configuration of Patent Document 2, if non-contact power feeding is performed while the vehicle is stopped for a short time in the same manner as described above, the power loss of the system power source similarly increases, and thus stable power supply may be difficult.

また、本発明に係る移動車両給電システムにおいて、取得された蓄電情報と蓄電量と位置情報とに基づいて、各給電エリアの給電エリア側蓄電装置のそれぞれの充電量を調整する調整手段を備えることが好ましい。   The mobile vehicle power supply system according to the present invention further includes an adjustment unit that adjusts each charge amount of the power supply area side power storage device of each power supply area based on the acquired power storage information, the power storage amount, and the position information.

また、本発明に係る移動車両給電システムにおいて、移動車両の走行経路に設けられ、移動車両との間で無線により通信を行うことで移動車両の蓄電情報と位置情報とを取得する複数の無線通信機と、最適な給電エリアまでの最適経路を探索する最適経路手段と、無線通信機によって最適給電エリアと最適経路とを移動車両に提供する提供手段と、を備えることが好ましい。   Further, in the mobile vehicle power feeding system according to the present invention, a plurality of wireless communications that are provided on a travel route of the mobile vehicle and acquire the storage information and the position information of the mobile vehicle by performing wireless communication with the mobile vehicle. It is preferable to include an aircraft, an optimum route means for searching for an optimum route to the optimum power supply area, and a providing means for providing the mobile vehicle with the optimum power supply area and the optimum route by a wireless communication device.

上記構成によれば、系統電源からの電力を給電エリアに設けられる給電エリア側蓄電装置に充電した後、給電エリア側蓄電装置の放電を利用して系統電源の電力を非接触で移動車両に送電する。これにより、系統電源から直接ではなく、給電エリア側蓄電装置を介して移動車両に電力を給電するため、例えば短時間の給電を行う時でも安定した電力供給が可能となる。   According to the above configuration, after the power from the system power supply is charged in the power supply area side power storage device provided in the power supply area, the power of the system power supply is transmitted to the mobile vehicle in a non-contact manner using the discharge of the power supply area side power storage device.

The power supply area 300 includes the power supply point 60, the power supply area side power storage device 30, and the power transmission device 50.

移動車両６は、街等に設けられる走行経路８（換言すれば道路）を走行して目的地までの移動を行うための車両である。そして、走行経路８の側部には、交通信号機９と無線通信機４０等を取り付けるための構造物１５が所定の間隔で配置される。   The moving vehicle 6 is a vehicle for traveling to a destination by traveling on a travel route 8 (in other words, a road) provided in a town or the like. And the structure 15 for attaching the traffic signal 9 and the radio | wireless communication apparatus 40 grade | etc., Is arrange | positioned in the side part of the driving | running route 8 with a predetermined space | interval.

交通信号機９は、複数の移動車両６を走行経路８を安全かつ円滑に走行させるために、例えば図示しない交差点等において設けられる信号機である。そして、交通信号機９は、移動車両６に対して進行可能であることを表示する青信号と、移動車両６に対して進行注意であることを表示する黄信号と、移動車両６に対して進行禁止であることを表示する赤信号といった３つの信号から構成されている。もちろん、交通信号機９は、これらの信号の種類に限定されず、例えば青信号が点灯している場合には進行可能であることを表示し、青信号が点滅へと切り替わった場合には進行注意であることを表示し、その後青信号から赤信号へと切り替わった場合には進行禁止であることを表示するものであってもよい。   The traffic signal 9 is a signal provided at, for example, an intersection (not shown) in order to cause the plurality of moving vehicles 6 to travel safely and smoothly on the travel route 8. The traffic signal 9 is a green signal indicating that the vehicle can proceed with respect to the moving vehicle 6, a yellow signal indicating that the vehicle is careful of traveling with respect to the moving vehicle 6, and a travel prohibition for the moving vehicle 6. It is composed of three signals such as a red signal for indicating that it is. Of course, the traffic light 9 is not limited to these types of signals. For example, when the green light is lit, the traffic signal 9 indicates that the vehicle can proceed, and when the green light switches to blinking, attention is paid to the progress. May be displayed, and then, when switching from the green signal to the red signal, it is displayed that the progress is prohibited.

系統電源２００は、電力会社が保有する商用電力を各給電エリア３００に供給するための電源である。系統電源２００は、電力線１０６を用いて各給電エリア３００の給電エリア側蓄電装置３０に接続される。系統電源２００は、後述する制御部１００からの指令により各給電エリア側蓄電装置３０への充放電制御を行う。電力線１０６は、電力を給電エリア側蓄電装置３０に送電するための電気配線であるが、ＰＬＣ（Ｐｏｗｅｒ Ｌｉｎｅ Ｃｏｍｍｕｎｉｃａｔｉｏｎｓ）技術により通信回線として利用することもできる。これにより、系統電源２００は、各給電エリア側蓄電装置３０の蓄電量を取得することもできる。   The system power source 200 is a power source for supplying commercial power held by the power company to each power supply area 300. The system power supply 200 is connected to the power supply area side power storage device 30 of each power supply area 300 using the power line 106.

The power feeding area side power storage device 30 is disposed in the vicinity of the structure 15 to which the traffic signal device 9 is attached. The power feeding area side power storage device 30 is a battery pack that combines a plurality of single cells to have a predetermined voltage, stores the power from the system power supply 200 by charging, and discharges the power to the power transmission device 50 by discharging. This is a secondary battery that can be output. The power storage area side power storage device 30 is charged by the electric power from the system power source 200 when the traffic signal 9 is green, and is controlled via the power transmission device 50 when the traffic signal 9 is red. Then, electric power is discharged to the moving vehicle 6. Of course, the power supply area side power storage device 30 may be other than the secondary battery as long as it can be charged and discharged, and may be configured using a capacitor, for example.

送電装置５０は、給電ポイント６０の地下に埋め込んで配置される装置である。また、送電装置５０は、給電ポイント６０に移動車両６が停車できる数に対応して複数の送電装置５０が配置されている。送電装置５０は、移動車両６の受電装置６２に対して電力を送電するための装置であり、詳細な機能と構成については後述する。   The power transmission device 50 is a device that is embedded in the basement of the power supply point 60. In addition, the power transmission device 50 includes a plurality of power transmission devices 50 corresponding to the number of moving vehicles 6 that can be stopped at the power supply point 60. The power transmission device 50 is a device for transmitting power to the power reception device 62 of the mobile vehicle 6, and detailed functions and configurations will be described later.

FIG. 6 is a flowchart showing a procedure in which the moving vehicle 6 acquires the optimum power feeding area and the optimum route information and starts feeding.

まず、図４を用いて、最初に移動車両６から制御部１００に対して車両に関する情報を送信する手順について説明する。移動車両６において移動車両側蓄電装置６４の蓄電状態であるＳＯＣ（Ｓｔａｔｅ Ｏｆ Ｃｈａｒｇｅ）を確認する（Ｓ２）。そして、移動車両６が継続して走行するために充電が必要なエネルギを算出する（Ｓ４）。次に、Ｓ４において算出されたエネルギに基づいて、当該移動車両６に給電が必要かどうかを判断する（Ｓ６）。ここで、当該移動車両６に給電が必要でないと判断すれば、再びＳ２に戻る。また、当該移動車両６に給電が必要であると判断すれば、移動車両６の蓄電情報や走行経路８における当該移動車両６の位置情報といった車両情報が車両側通信機６６から無線通信機４０に対して送信される（Ｓ８）。その後、ＥＮＤ処理へと進む。なお、これらの手順の処理は、移動車両６に搭載される図示しない車両制御装置の機能によって実行される。   First, the procedure for transmitting information about a vehicle from the moving vehicle 6 to the control unit 100 first will be described with reference to FIG. In the moving vehicle 6, the state of charge (SOC) that is the state of charge of the moving vehicle side power storage device 64 is confirmed (S2). And the energy which needs charging in order for the moving vehicle 6 to drive | work continuously is calculated (S4). Next, based on the energy calculated in S4, it is determined whether or not the mobile vehicle 6 needs to be fed (S6). Here, if it is determined that power supply is not necessary for the moving vehicle 6, the process returns to S2. If it is determined that the mobile vehicle 6 needs to be supplied with power, vehicle information such as storage information of the mobile vehicle 6 and position information of the mobile vehicle 6 in the travel route 8 is transferred from the vehicle-side communication device 66 to the wireless communication device 40. It is transmitted to (S8). Thereafter, the process proceeds to the END process. In addition, the process of these procedures is performed by the function of the vehicle control apparatus (not shown) mounted in the moving vehicle 6. FIG.

次に、図５を用いて、制御部１００で移動車両給電プログラムが実行されて最適給電エリアの探索とその給電エリアまでの最適ルートの情報を当該移動車両６に送信される手順について説明する。まず、無線通信機４０を介して移動車両６の蓄電情報と位置情報を取得する（Ｓ１０）。この機能は、ＣＰＵ１１０の車両蓄電情報取得モジュール１１２と車両位置情報取得モジュール１１４の機能によって実行される。   Next, with reference to FIG. 5, a description will be given of a procedure in which the moving vehicle power supply program is executed by the control unit 100 and information about the optimal route to the power supply area is transmitted to the mobile vehicle 6. First, the storage information and position information of the moving vehicle 6 are acquired via the wireless communication device 40 (S10). This function is executed by the functions of the vehicle power storage information acquisition module 112 and the vehicle position information acquisition module 114 of the CPU 110.

続いて、各給電エリア３００における給電エリア側蓄電装置３０の蓄電量を確認する（Ｓ１２）。この機能は、ＣＰＵ１１０の給電エリア蓄電情報取得モジュール１１３の機能によって実行される。   Then, the power storage amount of the power supply area side power storage device 30 in each power supply area 300 is confirmed (S12). This function is executed by the function of the power supply area power storage information acquisition module 113 of the CPU 110.

さらに、各給電エリア３００における給電エリア側蓄電装置３０の蓄電量に基づいて、各給電エリア側蓄電装置間の蓄電量の調整を行うように系統電源２００に対して指令を与える（Ｓ１４）。この指令を受けて、さらに交通信号機９が青信号のときに該当給電エリア側蓄電装置３０に対して充電が行われる。この機能は、ＣＰＵ１１０の系統電源制御モジュール１１８の機能によって実行される。   Further, the system power supply 200 is commanded to adjust the amount of electricity stored between the power supply area side power storage devices based on the amount of power stored in the power supply area side power storage device 30 in each power supply area 300 (S14). In response to this command, the power supply area side power storage device 30 is charged when the traffic light 9 is a green light. This function is executed by the function of the system power supply control module 118 of the CPU 110.

そして、移動車両６の蓄電情報及び位置情報と、給電エリア側蓄電装置３０の蓄電量とに基づいて、その移動車両６が給電を行うのに最適な給電エリア３００を探索する（Ｓ１６）。この機能は、ＣＰＵ１１０の最適給電エリア探索モジュール１１５の機能によって実行される。   Then, based on the power storage information and position information of the moving vehicle 6 and the power storage amount of the power supply area side power storage device 30, a power supply area 300 optimum for the mobile vehicle 6 to perform power supply is searched (S16). This function is executed by the function of the optimum power supply area search module 115 of the CPU 110.

次に、Ｓ１６において探索された最適給電エリア３００までの最適ルートを探索する（Ｓ１８）。この機能は、ＣＰＵ１１０の最適ルート探索モジュール１１６の機能によって実行される。   Next, the optimum route to the optimum power feeding area 300 searched in S16 is searched (S18). This function is executed by the function of the optimum route search module 116 of the CPU 110.

続いて、Ｓ１６，Ｓ１８で探索された給電エリア３００とその給電エリア３００までの最適ルートの情報について無線通信機４０を介して当該移動車両６に対して送信する（Ｓ２０）。この機能は、ＣＰＵ１１０の給電エリア・ルート情報送信モジュール１１９の機能によって実行される。その後、ＥＮＤ処理へと進む。   Subsequently, information on the power supply area 300 searched in S16 and S18 and the optimum route to the power supply area 300 is transmitted to the mobile vehicle 6 via the wireless communication device 40 (S20). This function is executed by the function of the power supply area / route information transmission module 119 of the CPU 110. Thereafter, the process proceeds to the END process.

次に、図６を用いて、移動車両６が最適給電エリアと最適ルート情報を取得して給電を開始する手順について説明する。まず、移動車両６が、無線通信機４０から制御部１００によって探索された最適給電エリアの情報と最適ルートの情報を受信する（Ｓ２２）。続いて、移動車両６は、Ｓ２２において受信した最適ルートに基づいて、当該給電エリア３００に移動する（Ｓ２４）。なお、これらの手順の処理は、移動車両６に搭載される図示しない車両制御装置の機能によって実行される。   Next, a procedure in which the moving vehicle 6 acquires the optimum power feeding area and the optimum route information and starts feeding will be described with reference to FIG. First, the moving vehicle 6 receives information on the optimum power feeding area and information on the optimum route searched for by the control unit 100 from the wireless communication device 40 (S22). Subsequently, the moving vehicle 6 moves to the power supply area 300 based on the optimum route received in S22 (S24). In addition, the process of these procedures is performed by the function of the vehicle control apparatus (not shown) mounted in the moving vehicle 6. FIG.

そして、交通信号機９が赤信号となり、当該移動車両６が当該給電エリア３００の給電ポイント６０に停車して送電装置５０と受電装置６２とが送受電可能な対応する位置となったときに必要な電力が供給される。つまり、当該移動車両６に対して給電が行われる（Ｓ２６）。そして、受電装置６２から移動車両側蓄電装置６４に必要な電力が充電される。   And it is necessary when the traffic signal 9 becomes a red signal and the mobile vehicle 6 stops at the power supply point 60 of the power supply area 300 and the power transmission device 50 and the power reception device 62 are in corresponding positions where power can be transmitted and received. Power is supplied. That is, power is supplied to the moving vehicle 6 (S26). Then, necessary power is charged from the power receiving device 62 to the moving vehicle side power storage device 64.

このように、移動車両給電システム１０によれば、系統電源２００から一旦、給電エリア側蓄電装置３０に電力を溜めておき、給電エリア側蓄電装置３０の充放電により移動車両６に電力を送電するため、系統電源２００の損失はなく安定した電力供給ができる。また、移動車両６は、制御部１００によって探索された最適給電エリアまでの最適ルートに基づいて移動して給電を行える。したがって、安定した電力の下で移動車両６の走行を行うことが可能となる。   Thus, according to the mobile vehicle power supply system 10, power is temporarily stored in the power supply area side power storage device 30 from the system power supply 200, and power is transmitted to the mobile vehicle 6 by charging / discharging of the power supply area side power storage device 30. Therefore, there is no loss of the system power supply 200 and stable power supply can be performed. In addition, the moving vehicle 6 can move and supply power based on the optimal route to the optimal power supply area searched by the control unit 100. Therefore, it is possible to travel the mobile vehicle 6 under stable power.
