まず、移動充電車1は、被充電車2からの要求に基づき、被充電車2へ接近する(S101)。 First, the mobile charge vehicle 1, based on a request from the charging car 2 is closer to the charging car 2 (S101). なお、この要求方法は、移動充電車1を所有する会社等の第三者を介する方法及び車々間通信部12を用いての通信、もしくはハザードでの合図等の方法でもよい。 Incidentally, the request method, the communication using the method and the inter-vehicle communication unit 12 via a third party company, etc. that owns the mobile charge vehicle 1, or may be a method of signaling such a hazard. 被充電車2へ接近後、制御部11が測距センサ13により、被充電車2と自車(移動充電車1)との測距データの取得を行い(S102)、移動充電車1と被充電車2が充電可能な状態であり、充電可能範囲にあるか否かの判断を行う(S103)。 After approaching to be charged wheel 2, the control unit 11 is distance measuring sensor 13, and retrieve the distance measurement data between the charging car 2 and the vehicle (mobile charge vehicle 1) (S102), the mobile charge car 1 and the a state rechargeable charging car 2, a determination of whether or not the chargeable range (S103). ここで充電不可能な場合、充電可能な状態となるまで、制御部11は、移動充電車1を移動させるよう運転者もしくは図示しない駆動系に指示を与え、車間距離を制御し(S112)、S103の処理を繰り返す。 Here, if not possible charging until chargeable state, the control unit 11 gives an instruction to the driver or a not shown drive system to move the moving charge car 1, by controlling the inter-vehicle distance (S112), It repeats the process of S103.

充電可能範囲となった場合、制御部11は、測距センサ13、車間距離維持部14により、移動充電車1と被充電車2の車間距離を、充電可能な一定の距離となるよう制御を行う(S104,距離維持ステップ)。 If a chargeable range, the control unit 11, the distance measuring sensor 13, the headway distance maintenance unit 14, a moving charge car 1 vehicle distance of the charging car 2, a control such as a rechargeable constant distance performing (S104, distance maintenance steps). 充電可能距離の維持後、制御部11は、車々間通信部12Aにより、被充電車2の車々間通信部12Bへ課金の通信を行い(S105,課金ステップ)、課金が正常にできたか否かの判断を行う(S106)。 After maintaining the chargeable distance, the control unit 11, the inter-vehicle communication unit 12A, to communicate billing to be charged cars 2 of the inter-vehicle communication unit 12B (S105, charging step), billing determines whether could successfully is carried out (S106). なお、ここで被充電車2が正常に課金できない状態であれば、充電不可となり、本フローは終了となる(S113)。 Note that if here, the state in which the charging car 2 can not be charged properly, it is unchargeable, this flow is finished (S113). 課金が正常に行えた場合、制御部11は、大容量バッテリ15、インバータ16により、被充電車2の充電コイル17Bへ充電コイル17Aから電力の充電を開始する(S107,S108,充電ステップ,非接触充電ステップ)。 If the charging is performed normally, the control unit 11, the high capacity battery 15, an inverter 16, to start power charging from the charging coil 17A to the charging coil 17B of the charging car 2 (S107, S108, charging step, the non contact charging step).

充電開始後、制御部11は、充電が完了したか否かを判定し、充電不十分であるならば(S109,NO)、S108の処理を続ける。 After start of charging, the control unit 11 determines whether charging is completed, if an insufficient charging (S109, NO), continues the process of S108. なお、上述した判定方法は、充電開始(S107)からの時間を制御部11でカウントし、一定時間経過後に終了とする。 The determination method described above, and counted in the control unit 11 the time from the start of charging (S107), and ends after a predetermined time has elapsed. また、車々間通信部12Aによる無線通信等により、被充電車2の充電状態を移動充電車1の制御部11に通知し、その情報を制御部11が判断して充電を終了させることも可能である。 Also, by wireless communication or the like according to vehicle communication unit 12A, and notifies the state of charge of the charging car 2 to the control unit 11 of the mobile charge car 1, also possible to terminate the charging by determining the information control unit 11 is is there. 制御部11が充電完了と判断した場合(S109,YES)、制御部11は、充電コイル17Aからの充電を終了させ、車間距離維持部14により、移動充電車1、被充電車2間の距離を保持する制御を解除し(S110)、本フローは終了となる(S111)。 If the control unit 11 determines that charging is completed (S109, YES), the control unit 11 ends the charging of the charging coil 17A, the inter-vehicle distance maintaining unit 14, the mobile charge vehicle 1, the distance between the charging car 2 releases the control to maintain the (S110), this flow is finished (S 111).

本実施の形態によれば、制御部11、車間距離維持部14、測距センサ13により、被充電車2へ移動充電車1が移動しながら一定の距離を保持することができ、大容量バッテリ15、インバータ16、充電コイル17により、非接触にて被充電車2へ充電を行うことができる。 According to this embodiment, the control unit 11, the inter-vehicle distance maintenance portion 14, the distance measuring sensor 13, it is possible to maintain a constant distance while moving the moving charge car 1 to be charged wheel 2, large-capacity battery 15, an inverter 16, a charging coil 17, can be charged to be charged wheel 2 in a non-contact. よって、被充電車2へ移動充電車1が移動中に充電を行うことができる。 Therefore, the mobile charge vehicle 1 can be charged while moving the object to be charged vehicles 2. これにより、バッテリ枯渇による路上停車を防ぐことができ、停車車両を原因とする事故や渋滞を防ぐことができ、また、環境負荷低減等に大きく貢献することができる。 This prevents the road vehicle stop by the battery depletion, it is possible to prevent accidents and congestion caused by vehicles stop, also can greatly contribute to reducing environmental impact, and the like.

上述した実施の形態1では、充電を一定時間経過後に終了するとしたが、移動充電車1が被充電車2のバッテリ残量、目的地、被充電車2の性能諸元データを受信後、充電所マップを参照し、現在地から最も近い充電所までの距離および必要電力量を計算し、必要な充電量のみ充電を行っても良い。 In the first embodiment described above, although the charging is terminated after a predetermined time has elapsed, the remaining battery capacity of the mobile charge vehicle 1 to be charged wheel 2, a destination, after receiving the performance specification data of the charging car 2, charging Referring to Tokoro map, and calculates the distance and the required power amount from the current position to the nearest charging station, may be performed only charged charge amount required.
