Description

本発明は、車両へ非接触の給電を行う給電装置及び非接触で受電を行う車両の受電装置に関する。   The present invention relates to a power feeding device that performs non-contact power feeding to a vehicle and a power receiving device for a vehicle that performs non-contact power reception.

近年、電気で走行する車両（例えば電気自動車またはハイブリッド自動車など）に対して、非接触で給電を行う給電システムについて開発がなされている。このような給電システムでは、車両に受電装置が搭載される一方、駐車スペースの地面等に給電装置が設置される。そして、車両が駐車スペースに停車している間に給電装置から受電装置へ送電が行われる。受電装置の受電部と給電装置の給電部とには、例えば受電用のコイルと給電用のコイルとがそれぞれ設けられ、給電部から受電部へ電磁誘導方式で電力が送られる。   2. Description of the Related Art In recent years, power supply systems that perform power supply in a contactless manner have been developed for vehicles that run on electricity (for example, electric vehicles or hybrid vehicles). In such a power feeding system, the power receiving device is mounted on the vehicle, while the power feeding device is installed on the ground or the like of the parking space. Then, power is transmitted from the power feeding device to the power receiving device while the vehicle is stopped in the parking space. For example, a power reception coil and a power supply coil are provided in the power reception unit of the power reception device and the power supply unit of the power supply device, respectively, and power is transmitted from the power supply unit to the power reception unit by an electromagnetic induction method.

また、本発明に関連する技術として、特許文献１には、次のような非接触の給電システムが開示されている。この給電システムは、車両が停止した状態で給電が行われるように、車両のパーキングブレーキが掛けられた場合に、給電要求を給電装置へ送信できるようにしたものである。   Further, as a technique related to the present invention, Patent Document 1 discloses the following non-contact power feeding system. This power supply system is configured so that a power supply request can be transmitted to a power supply device when a parking brake of the vehicle is applied so that power is supplied in a state where the vehicle is stopped.

特開２０１０−２２６９４５号公報JP 2010-226945 A

電磁誘導方式により非接触で車両に給電を行う給電システムにおいては、給電装置の給電部と受電装置の受電部とが数センチ以内の誤差で位置合わせされた状態で、給電を行う必要がある。給電部と受電部との位置が合っていないと、漏洩磁界および不要輻射が増大して、正常な給電が行えなくなるという課題が発生する。   In a power supply system that supplies power to a vehicle in a non-contact manner by an electromagnetic induction method, it is necessary to perform power supply in a state where the power supply unit of the power supply device and the power reception unit of the power reception device are aligned with an error within several centimeters. If the positions of the power feeding unit and the power receiving unit do not match, a problem arises that leakage magnetic field and unnecessary radiation increase, and normal power feeding cannot be performed.

また、このような非接触の給電システムでは、給電の開始時に両者の位置が正確に合っていても、その後の給電中に両者の位置がずれてしまうと、上記と同様に漏洩磁界および不要輻射が増大して異常な給電状態となってしまう。   Further, in such a non-contact power feeding system, even if both positions are accurately aligned at the start of power feeding, if both positions are shifted during the subsequent power feeding, a leakage magnetic field and unnecessary radiation are similarly generated. Increases to an abnormal power supply state.

例えば、上記特許文献１のシステムでは、パーキングブレーキが掛けられて車両の停止状態が確認されてから給電が開始されるが、給電中に、パーキングブレーキが緩められて車両が動いてしまうと、上記と同様に異常な給電状態が発生してしまう。また、パーキングブレーキが掛けられたままであっても、ブレーキの緩みや劣化等で制動の効き具合が悪くなっている場合に、上記と同様に異常な給電状態が発生しえる。例えば、車両に人がもたれかかった場合、傾斜途中に車輪が乗り上げて車両が停止している場合、可動物に車輪が乗り上げて車両が停止している場合、または、地震が発生した場合などに、停車中でも車両が数センチ程度移動してしまう可能性がある。   For example, in the system of Patent Document 1 above, power supply is started after the parking brake is applied and the stop state of the vehicle is confirmed, but if the parking brake is loosened and the vehicle moves during power supply, An abnormal power supply state occurs in the same manner as in FIG. Even when the parking brake is still applied, an abnormal power supply state can occur in the same manner as described above when the braking effectiveness is deteriorated due to looseness or deterioration of the brake. For example, when a person leans on the vehicle, when the vehicle is stopped by climbing a wheel while it is tilting, when the vehicle is stopped by moving a wheel on a movable object, or when an earthquake occurs There is a possibility that the vehicle may move about several centimeters even when the vehicle is stopped.

本発明の目的は、給電部と受電部との位置が合って給電が開始された後に、給電部と受電部の位置がずれて異常な給電状態が発生してしまうことを防止できる給電装置及び車両の受電装置を提供することである。   An object of the present invention is to provide a power feeding device capable of preventing an abnormal power feeding state from occurring due to the positions of the power feeding unit and the power receiving unit being shifted after the power feeding unit and the power receiving unit are positioned and power feeding is started. It is to provide a power receiving device for a vehicle.

A configuration is adopted in which power supply by the power supply unit is stopped when information indicating presence is received.

本発明の一態様に係る車両の受電装置は、車両に搭載される受電装置であって、前記車両の外部に設けられた給電装置の給電部から非接触で受電を行う受電部と、前記給電装置に設けられた給電側通信部と通信を行う車両側通信部と、前記車両に搭載されて前記車両の動きを検知する動き検知部の検知情報を入力する車両側制御部と、を具備し、前記車両側制御部は、前記受電部による受電の開始後、前記動き検知部から動き検知有りを示す検知情報を入力した場合に、動き検知有りを示す情報、或いは、給電を停止させる指令を前記車両側通信部から前記給電側通信部へ送信させる構成を採る。   A power receiving device for a vehicle according to an aspect of the present invention is a power receiving device mounted on a vehicle, the power receiving unit receiving power in a non-contact manner from a power feeding unit of a power feeding device provided outside the vehicle, and the power feeding A vehicle-side communication unit that communicates with a power supply-side communication unit provided in the apparatus; and a vehicle-side control unit that inputs detection information of a motion detection unit that is mounted on the vehicle and detects the movement of the vehicle.

The storage battery 102 is, for example, a large capacity lithium ion battery.

車両側通信部１０４と給電側通信部１０５とは、車両１０が給電装置３０の近傍にある状態で無線によりデータ通信可能にされる。これらの車両側通信部１０４と給電側通信部１０５とを介して、車両側制御部１０１と給電側制御部１０７とが無線により互いにデータ通信を行う。   The vehicle-side communication unit 104 and the power-feeding-side communication unit 105 can perform data communication wirelessly with the vehicle 10 in the vicinity of the power-feeding device 30. Via the vehicle side communication unit 104 and the power supply side communication unit 105, the vehicle side control unit 101 and the power supply side control unit 107 perform data communication with each other wirelessly.

給電部１０６は、給電用のコイルを有し、このコイルに交流電流を流して電磁誘導方式により受電部１０３へ電力を送る。   The power feeding unit 106 includes a power feeding coil, and an alternating current is supplied to the coil to send power to the power receiving unit 103 by an electromagnetic induction method.

受電部１０３は、受電用のコイルを有し、電磁誘導方式により給電部１０６から電力を受ける。そして、受電部１０３は、受電した電力を蓄電池１０２（その充電回路）へ送る。   The power receiving unit 103 has a power receiving coil, and receives power from the power feeding unit 106 by an electromagnetic induction method. And the power receiving part 103 sends the received electric power to the storage battery 102 (its charging circuit).

給電側制御部１０７は、制御プログラムを記憶した記憶手段を有し、この制御プログラムに従って、給電側通信部１０５を介して車両側制御部１０１から指令および情報を受け取り、また、給電部１０６の駆動制御を行う。   The power supply side control unit 107 includes a storage unit that stores a control program.

車輪速センサ１０８は、ＡＢＳ（Antilock Brake System）において車輪の回転状態を検出するために車両１０に設けられているセンサである。この車輪速センサ１０８は、車両１０のタイヤが微小量回転したことを検知可能なセンサであり、所定量の回転ごとに例えば１つの検出パルスを出力する。車輪速センサ１０８が検知可能なタイヤの回転量は、車両１０の移動量に換算して、短い長さ（例えば４センチなど）であり、受電部１０３と給電部１０６との位置合わせの許容誤差程度の長さに設定されている。なお、車輪速センサ１０８としては、ＡＢＳの車輪速センサを流用したものでなく、受電の制御のために専用に車両１０に設けられたものを採用してもよい。   The wheel speed sensor 108 is a sensor provided in the vehicle 10 for detecting the rotation state of the wheel in ABS (Antilock Brake System). The wheel speed sensor 108 is a sensor that can detect that the tire of the vehicle 10 has rotated a minute amount, and outputs, for example, one detection pulse for each predetermined amount of rotation. The rotation amount of the tire that can be detected by the wheel speed sensor 108 is a short length (for example, 4 centimeters or the like) in terms of the movement amount of the vehicle 10, and an allowable error in alignment between the power receiving unit 103 and the power feeding unit 106. It is set to a length of about. As the wheel speed sensor 108, an ABS wheel speed sensor may be used instead of a dedicated one provided in the vehicle 10 for power reception control.

図２は、実施の形態１の充電手順を説明するフローチャートである。図２において、ステップＳ２０１，Ｓ２０２はユーザが行う処理であり、ステップＳ２０３〜Ｓ２０６は車両側制御部１０１が制御プログラムに従って実行する処理である。   FIG. 2 is a flowchart for explaining the charging procedure of the first embodiment. In FIG. 2, steps S201 and S202 are processes performed by the user, and steps S203 to S206 are processes executed by the vehicle-side control unit 101 according to the control program.

車両１０の蓄電池１０２へ充電を行う場合、先ず、ユーザは、車両１０を所定の精度で充電用の停止位置に停車させる。これにより、受電部１０３と給電部１０６とが所定の誤差内の精度で位置合わせされる（ステップＳ２０１）。続いて、ユーザは、充電開始の操作を行う（ステップＳ２０２）。操作が行われなければ（ステップＳ２０２の「無し」）充電動作は開始されずに、この充電処理は終了する。   When charging the storage battery 102 of the vehicle 10, first, the user stops the vehicle 10 at a charging stop position with a predetermined accuracy. Thereby, the power receiving unit 103 and the power feeding unit 106 are aligned with accuracy within a predetermined error (step S201). Subsequently, the user performs an operation for starting charging (step S202). If no operation is performed (“None” in step S202), the charging operation is not started and the charging process ends.

なお、ステップＳ２０２の充電開始の操作は、ユーザが車両１０内で図示略の操作スイッチを操作することで実行されるように構成できる。そして、この操作スイッチの操作信号が車両側制御部１０１へ送られることで、車両側制御部１０１がその後の充電処理を開始する。   Note that the operation for starting charging in step S202 can be configured such that the user operates the operation switch (not shown) in the vehicle 10. And the operation signal of this operation switch is sent to the vehicle side control part 101, and the vehicle side control part 101 starts the subsequent charging process.

或いは、ステップＳ２０２の充電開始の操作は、駐車場に充電開始の操作スイッチを設けて、ユーザがこの操作スイッチを操作することで実行されるようにしてもよい。そして、この操作スイッチの操作信号が無線により車両側通信部１０４を介して車両用制御部１０１へ送られるように構成してもよい。或いは、駐車場に充電開始の操作スイッチが設けられ、この操作スイッチの操作信号が、給電側制御部１０７に入力される構成としてもよい。そして、この操作信号が、給電側通信部１０５と車両側通信部１０４との通信により車両側制御部１０１へ送られて、充電処理が開始されてもよい。また、車両１０が充電用の停止位置に停車したことを検出する検出装置を設け、この検出装置が車両の停車を検出したことを充電開始の操作とみなして、この検出信号が車両側通信部１０４へ送られるように構成してもよい。   Alternatively, the charge start operation in step S202 may be executed by providing a charge start operation switch in the parking lot and operating the operation switch by the user. The operation signal of the operation switch may be transmitted to the vehicle control unit 101 via the vehicle side communication unit 104 by radio. Alternatively, an operation switch for starting charging may be provided in the parking lot, and an operation signal of the operation switch may be input to the power supply side control unit 107. And this operation signal may be sent to the vehicle side control part 101 by communication with the electric power feeding side communication part 105 and the vehicle side communication part 104, and a charging process may be started. In addition, a detection device that detects that the vehicle 10 has stopped at the charging stop position is provided, and that the detection device detects that the vehicle has stopped is regarded as an operation to start charging, and this detection signal is transmitted to the vehicle-side communication unit. It may be configured to be sent to 104.

充電開始の操作があると、車両側制御部１０１は、給電開始要求を車両側通信部１０４を介して給電装置３０へ送信する（ステップＳ２０３）。この給電開始要求は、給電側通信部１０５を介して給電側制御部１０７へ送られ、この要求に基づき給電側制御部１０７は給電部１０６の駆動制御を行って給電を開始する。なお、給電開始要求は、車両の速度がゼロのとき、すなわち、車両が停止中であることが確認されたときのみ送信可能にすると好ましい。   When there is an operation to start charging, the vehicle-side control unit 101 transmits a power supply start request to the power supply device 30 via the vehicle-side communication unit 104 (step S203). This power supply start request is sent to the power supply side control unit 107 via the power supply side communication unit 105. Based on this request, the power supply side control unit 107 performs drive control of the power supply unit 106 to start power supply. The power supply start request is preferably transmitted only when the vehicle speed is zero, that is, when it is confirmed that the vehicle is stopped.

給電開始要求を送信したら、続いて、車両側制御部１０１は、車輪速センサ１０８の出力の監視（ステップＳ２０４）と、充電状況（充電完了となったか否か）の監視（ステップＳ２０５）とを繰り返し実行する処理ループへ処理を移行させる。車両側制御部１０１は、例えば蓄電池１０２が満充電となった場合に充電完了と判別する。そして、車輪速センサ１０８の出力があって車両側制御部１０１が車輪が回転したと判別するか、或いは、車両側制御部１０１が充電完了と判別すると、車両側制御部１０１の処理がステップＳ２０４，Ｓ２０５の処理ループから抜ける。   After transmitting the power supply start request, the vehicle-side control unit 101 subsequently monitors the output of the wheel speed sensor 108 (step S204) and monitors the charging status (whether charging is complete) (step S205). Shift processing to a processing loop that is repeatedly executed. The vehicle-side control unit 101 determines that charging is complete when, for example, the storage battery 102 is fully charged. Then, when there is an output from the wheel speed sensor 108 and the vehicle-side control unit 101 determines that the wheel has rotated, or when the vehicle-side control unit 101 determines that charging is complete, the processing of the vehicle-side control unit 101 performs step S204. , S205 is exited from the processing loop.

処理ループを抜けたら、車両側制御部１０１は、給電停止要求を車両側通信部１０４を介して給電装置３０へ送信する（ステップＳ２０６）。この給電停止要求は、給電側通信部１０５を介して給電側制御部１０７へ送られ、給電側制御部１０７はこの要求に基づき給電部１０６を制御して給電を停止させる。そして、充電処理が終了する。   After exiting the processing loop, the vehicle side control unit 101 transmits a power supply stop request to the power supply apparatus 30 via the vehicle side communication unit 104 (step S206). The power supply stop request is sent to the power supply side control unit 107 via the power supply side communication unit 105, and the power supply side control unit 107 controls the power supply unit 106 based on this request to stop power supply. Then, the charging process ends.

この実施の形態１の受電装置２０によれば、給電中に車両側制御部１０１が車輪速センサ１０８の出力を監視して、この出力があった場合に、給電を停止させるようになっている。従って、車両用電力供給システムにおいては、給電中に受電部１０３と給電部１０６との間に位置ズレが生じた場合でも、漏洩磁界および不要輻射が増大するような異常な給電状態になることが防止される。   According to the power receiving device 20 of the first embodiment, the vehicle-side control unit 101 monitors the output of the wheel speed sensor 108 during power feeding, and stops feeding when there is this output. . Therefore, in the vehicular power supply system, even when a positional deviation occurs between the power receiving unit 103 and the power feeding unit 106 during power feeding, an abnormal power feeding state in which leakage magnetic field and unnecessary radiation increase may occur. Is prevented.

なお、実施の形態１において、車両１０は、車両１０の上下方向および左右方向の加速度を検出する加速度センサを備え、この加速度センサの出力が車両側制御部１０１へ出力される構成としてもよい。さらに、車両側制御部１０１は、車輪速センサ１０８の出力に基づき車両１０が前後方向に移動したことを判別するとともに、加速度センサの出力に基づき車両１０が上下方向または左右方向に変動したことを判別する構成としてもよい。そして、車両側制御部１０１は、これら前後方向の移動を判別した場合、または、上下方向または左右方向の変動を判別した場合に、給電を停止させるための制御を行ってもよい。   In the first embodiment, the vehicle 10 may include an acceleration sensor that detects the acceleration in the vertical direction and the horizontal direction of the vehicle 10, and the output of the acceleration sensor may be output to the vehicle-side control unit 101. Further, the vehicle-side control unit 101 determines that the vehicle 10 has moved in the front-rear direction based on the output of the wheel speed sensor 108, and determines that the vehicle 10 has fluctuated in the vertical direction or the left-right direction based on the output of the acceleration sensor. It is good also as a structure to discriminate | determine. And the vehicle side control part 101 may perform control for stopping electric power feeding, when the movement of these front-back directions is discriminate | determined, or when the fluctuation | variation of the up-down direction or the left-right direction is discriminate | determined.

このような構成とすることで、給電中に車両１０が前後方向に移動した場合のみならず、左右または上下に変動するような事態が生じた場合にも、給電を停止させて、漏洩磁界および不要輻射が増大するような異常な給電状態になることを防止することができる。   By adopting such a configuration, not only when the vehicle 10 moves in the front-rear direction during power feeding, but also when a situation that fluctuates left and right or up and down occurs, power feeding is stopped and leakage magnetic field and It is possible to prevent an abnormal power supply state in which unnecessary radiation increases.

（実施の形態２）
本発明の実施の形態２の車両用電力供給システムは、実施の形態１のシステムと同様の構成であり、処理の一部が実施の形態１と異なるのみである。同様の構成および処理については同一符号を付して説明を省略する。 (Embodiment 2)
The vehicular power supply system according to the second embodiment of the present invention has the same configuration as the system according to the first embodiment, and only part of the processing is different from that of the first embodiment. Similar components and processes are denoted by the same reference numerals and description thereof is omitted.

図３は、実施の形態１の充電手順を説明するフローチャートである。   FIG. 3 is a flowchart illustrating a charging procedure according to the first embodiment.

実施の形態２では、実施の形態１と同様に、図３のステップＳ２０１〜Ｓ２０３の処理が行われた後、ステップＳ２０４，Ｓ２０５の処理ループへ移行する。そして、処理ループの中で充電完了と判断されると、ステップＳ２０６で給電停止要求が給電装置３０へ送られて給電が停止される。   In the second embodiment, similarly to the first embodiment, after the processing of steps S201 to S203 in FIG. 3 is performed, the process proceeds to a processing loop of steps S204 and S205. When it is determined that charging is completed in the processing loop, a power supply stop request is sent to the power supply apparatus 30 in step S206 to stop power supply.

また、実施の形態２では、ステップＳ２０４，Ｓ２０５の処理ループ中に車輪速センサ１０８の出力があって処理ループを抜けると、車両側制御部１０１は、動き検知情報を車両側通信部１０４を介して給電装置３０へ送信する（ステップＳ２０７）。この動き検知情報は、受電部１０３と給電部１０６との位置がずれて、この位置ズレが許容誤差を上回る可能性のあることを示す情報となる。そして、動き検知情報が送信されたら、給電部１０６の停止を確認したあと車両側制御部１０１は充電処理を終了する。   Further, in the second embodiment, when there is an output from the wheel speed sensor 108 during the processing loop of steps S204 and S205 and the processing loop is exited, the vehicle-side control unit 101 sends the motion detection information via the vehicle-side communication unit 104. To the power feeding apparatus 30 (step S207). This motion detection information is information indicating that the positions of the power reception unit 103 and the power supply unit 106 are shifted and this positional deviation may exceed the allowable error. And if motion detection information is transmitted, after confirming the stop of the electric power feeding part 106, the vehicle side control part 101 will complete | finish a charging process.

図４は、実施の形態２の給電側制御部１０７の制御手順を示すフローチャートである。   FIG. 4 is a flowchart illustrating a control procedure of the power feeding side control unit 107 according to the second embodiment.

給電側制御部１０７は、給電開始前には、給電側通信部１０５の受信データを入力して給電開始要求の受信の監視を行う（ステップＳ３０１）。そして、給電側制御部１０７は、この給電開始要求が受信されたら、給電部１０６を駆動して給電を開始する（ステップＳ３０２）。   The power feeding side control unit 107 monitors reception of a power feeding start request by inputting reception data of the power feeding side communication unit 105 before starting power feeding (step S301). And the electric power feeding side control part 107 will drive the electric power feeding part 106, and will start electric power feeding, if this electric power feeding start request | requirement is received (step S302).

給電が開始されると、給電側制御部１０７は、受電装置２０からの動き検知情報の受信の監視（ステップＳ３０３）と、受信装置２０からの給電停止要求の受信の監視（ステップＳ３０４）とを行う処理ループへ処理を移行させる。そして、給電側通信部１０５を介して給電停止要求が受信されるか、或いは、動き検知情報が受信されると、給電側制御部１０７のステップＳ３０３，Ｓ３０４の処理ループを抜ける。   When the power feeding is started, the power feeding side control unit 107 monitors the reception of the motion detection information from the power receiving device 20 (step S303) and the reception of the power feeding stop request from the receiving device 20 (step S304). Shift processing to the processing loop to be performed. When a power supply stop request is received via the power supply side communication unit 105 or when motion detection information is received, the processing loop of steps S303 and S304 of the power supply side control unit 107 is exited.

ステップＳ３０３，Ｓ３０４の処理ループを抜けると、給電側制御部１０７は、給電部１０６を制御して給電を停止させる（ステップＳ３０５）。   After exiting the processing loop of steps S303 and S304, the power supply side control unit 107 controls the power supply unit 106 to stop the power supply (step S305).

この実施の形態２の受電装置２０によれば、給電中、車両側制御部１０１が、車輪速センサ１０８の出力を監視して、この出力があった場合に、給電装置３０へ動き検知情報を送信する。また、この実施の形態２の給電装置３０によれば、給電中、給電側制御部１０７が動き検知情報の受信の有無を監視し、この受信があった場合に、給電を停止させる。従って、車両用電力供給システムにおいては、給電中に受電部１０３と給電部１０６との間に位置ズレが生じた場合でも、漏洩磁界および不要輻射が増大するような異常な給電状態になることが防止される。   According to the power receiving device 20 of the second embodiment, during power feeding, the vehicle-side control unit 101 monitors the output of the wheel speed sensor 108, and when there is this output, motion detection information is sent to the power feeding device 30. Send. In addition, according to the power supply device 30 of the second embodiment, during power supply, the power supply side control unit 107 monitors whether or not motion detection information is received, and stops power supply when the motion detection information is received. Therefore, in the vehicular power supply system, even when a positional deviation occurs between the power receiving unit 103 and the power feeding unit 106 during power feeding, an abnormal power feeding state in which leakage magnetic field and unnecessary radiation increase may occur. Is prevented.

（実施の形態３）
図５は、本発明の実施の形態３の車両用電力供給システムの要部を示す構成図である。この実施の形態３の車両用電力供給システムの構成または動作において、実施の形態１と同様のものは同一符号を付して説明を省略する。 (Embodiment 3)
FIG. 5 is a configuration diagram showing a main part of the vehicle power supply system according to the third embodiment of the present invention. In the configuration or operation of the vehicle power supply system according to the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted.

実施の形態３の車両用電力供給システムでは、給電中における車両１０の僅かな移動を検知するために車輪速センサ１０８の代わりに、加速度センサ１０９を採用している。   In the vehicle power supply system according to the third embodiment, an acceleration sensor 109 is employed instead of the wheel speed sensor 108 in order to detect a slight movement of the vehicle 10 during power feeding.

図６には、加速度センサ１０９の作用を説明する図を示す。図６に示すように、加速度センサ１０９は、互いに直交する３軸方向の加速度をそれぞれ検出するセンサであり、車両１０に所定の向きで設置されて、検出出力を車両側制御部１０１へ送る。車両側制御部１０１は、この検出出力に基づいて、車両１０の進行方向Ｘｂの加速度、右側方向Ｙｂの加速度、鉛直下方向Ｚｂの加速度を認識することができる。また、加速度センサ１０９の出力には、車両１０が動いていないときでも、常に、重力加速度の出力が現れる。   FIG. 6 is a diagram for explaining the operation of the acceleration sensor 109. As shown in FIG. 6, the acceleration sensor 109 is a sensor that detects accelerations in three axial directions orthogonal to each other, is installed in the vehicle 10 in a predetermined direction, and sends a detection output to the vehicle-side control unit 101. Based on this detection output, the vehicle-side control unit 101 can recognize the acceleration in the traveling direction Xb, the acceleration in the right direction Yb, and the acceleration in the vertical downward direction Zb of the vehicle 10. Further, the acceleration sensor 109 always outputs a gravitational acceleration even when the vehicle 10 is not moving.

この加速度センサ１０９としては、車両１０に備わる何らかの機能（例えばカーナビケーション機能）のために車両１０に予め搭載されている加速度センサを流用してもよいし、受電の制御のために専用に設けられたものを採用してもよい。なお、加速度センサ１０９は、３軸のセンサに限られず、例えば車両１０の前後方向など、１軸方向の加速度のみを検出可能な構成でもよい。加速度センサ１０９が車両１０の前後方向の加速度を検知することで実施の形態１の車輪速センサ１０８の代替的な機能が実現される。また、前後方向の加速度を検知する加速度センサと、車両１０の上下方向または左右方向の加速度を検知する加速度センサとを組み合わせることで車両１０の動きの検出の確実性を向上させることができる。   As the acceleration sensor 109, an acceleration sensor mounted in advance in the vehicle 10 for some function (for example, a car navigation function) provided in the vehicle 10 may be used, or provided exclusively for power reception control. May be used. The acceleration sensor 109 is not limited to a three-axis sensor, and may be configured to detect only an acceleration in one axis direction such as the longitudinal direction of the vehicle 10, for example. An alternative function of the wheel speed sensor 108 of the first embodiment is realized by the acceleration sensor 109 detecting the longitudinal acceleration of the vehicle 10. Further, by combining the acceleration sensor that detects the acceleration in the front-rear direction and the acceleration sensor that detects the acceleration in the vertical direction or the left-right direction of the vehicle 10, the certainty of the detection of the movement of the vehicle 10 can be improved.

図７は、実施の形態３の充電手順を説明するフローチャートである。   FIG. 7 is a flowchart illustrating a charging procedure according to the third embodiment.

実施の形態３では、実施の形態１と同様にステップＳ２０１，Ｓ２０２の処理が行われて充電操作がなされると、車両側制御部１０１は、次のような処理を実行する。すなわち、先ず、車両側制御部１０１は、以降の加速度変化を求めるために、その時点（すなわち車両１０の停止時）の加速度センサ１０９の検出結果（加速度Ａｓ）を入力して、この値を記憶する（ステップＳ２０９）。続いて、車両側制御部１０１は、給電装置３０へ給電開始要求を送信する（ステップＳ２１０）。そして、この給電開始要求の送信により給電が開始される。   In the third embodiment, as in the first embodiment, when the processing of steps S201 and S202 is performed and a charging operation is performed, the vehicle-side control unit 101 executes the following processing. That is, first, the vehicle-side control unit 101 inputs a detection result (acceleration As) of the acceleration sensor 109 at that time point (that is, when the vehicle 10 is stopped) in order to obtain a subsequent acceleration change, and stores this value. (Step S209). Subsequently, the vehicle-side control unit 101 transmits a power supply start request to the power supply apparatus 30 (step S210). Then, power supply is started by transmitting the power supply start request.

給電が開始されたら、車両側制御部１０１は、加速度変化の有無と充電完了の監視を行う処理ループ（ステップＳ２１１〜Ｓ２１３）へ処理を移行させる。すなわち、車両側制御部１０１は、先ず、加速度センサ１０９のその時点の検出結果（加速度Ａｔ）を入力して、この加速度ＡｔからステップＳ２０９で記憶された加速度Ａｓを減算して、加速度変化を求める（ステップＳ２１１）。続いて、この加速度変化と閾値とを比較して、閾値を超えているか判別する（ステップＳ２１２）。その結果、閾値を超えていれば、ステップＳ２１１〜Ｓ２１３の処理ループから車両側制御部１０１の処理が抜ける。一方、閾値を超えていなければ、車両側制御部１０１は充電完了か確認し（ステップＳ２１３）、未完了であればステップＳ２１１へ戻り、完了であれば処理ループを抜ける。   When the power supply is started, the vehicle-side control unit 101 shifts the process to a processing loop (steps S211 to S213) that monitors the presence or absence of acceleration change and the completion of charging. That is, the vehicle-side control unit 101 first inputs the detection result (acceleration At) at that time of the acceleration sensor 109, and subtracts the acceleration As stored in step S209 from this acceleration At to obtain an acceleration change. (Step S211). Subsequently, the acceleration change is compared with a threshold value to determine whether the threshold value is exceeded (step S212). As a result, if the threshold value is exceeded, the processing of the vehicle-side control unit 101 exits from the processing loop of steps S211 to S213. On the other hand, if it does not exceed the threshold value, the vehicle-side control unit 101 confirms whether charging is complete (step S213), returns to step S211 if not completed, and exits the processing loop if completed.

ステップＳ２１２の判別処理の閾値は、次のように設定される。すなわち、加速度センサ１０９は、重量の大きな車両１０に固定されているため、小さな力や振動が車両１０へ加わった程度では、出力を変化させず、車両１０が前後左右に僅か（例えば、０．２〜２ｃｍ）に動くような大きな力が加わっても、出力の変化は比較的小さくなる。従って、上記の閾値には、このように車両１０が前後左右に僅かに動くような加速度変化が識別できる値が設定され、この閾値はほぼゼロとなる場合もある。   The threshold value for the discrimination process in step S212 is set as follows. In other words, since the acceleration sensor 109 is fixed to the heavy vehicle 10, the output is not changed as long as a small force or vibration is applied to the vehicle 10, and the vehicle 10 is slightly changed from front to back, left and right (for example, 0. Even when a large force such as 2 to 2 cm) is applied, the change in output is relatively small. Therefore, the threshold value is set to a value that can identify an acceleration change such that the vehicle 10 slightly moves back and forth and from side to side, and this threshold value may be almost zero.

ステップＳ２１１〜Ｓ２１３の処理ループ中、加速度変化が閾値を超えた場合、或いは車両側制御部１０１が充電完了と判別した場合には、車両側制御部１０１は給電停止要求を給電装置３０へ送信する（ステップＳ２１４）。この給電停止要求の送信により、給電装置３０の給電が停止されて、充電処理が終了する。   During the processing loop of steps S <b> 211 to S <b> 213, when the acceleration change exceeds the threshold value, or when the vehicle-side control unit 101 determines that charging is complete, the vehicle-side control unit 101 transmits a power supply stop request to the power supply device 30. (Step S214). By transmitting the power supply stop request, the power supply of the power supply device 30 is stopped, and the charging process is completed.

この実施の形態３の受電装置２０によれば、給電中に車両側制御部１０１が加速度センサ１０９の出力を監視し、この出力に基づき閾値以上の加速度変化が検出されると、給電を停止させるようになっている。従って、車両用電力供給システムにおいては、給電中に受電部１０３と給電部１０６との間に位置ずれが生じた場合でも、漏洩磁界および不要輻射が増大するような異常な給電状態になることが防止される。   According to the power receiving device 20 of the third embodiment, the vehicle-side control unit 101 monitors the output of the acceleration sensor 109 during power feeding, and stops power feeding when an acceleration change equal to or greater than a threshold is detected based on this output. It is like that. Therefore, in the vehicular power supply system, even if a positional shift occurs between the power receiving unit 103 and the power feeding unit 106 during power feeding, an abnormal power feeding state in which leakage magnetic field and unnecessary radiation increase may occur. Is prevented.

なお、加速度センサ１０９の感度が高くて、車両１０が全く動かないような小さな振動等によってもセンサ出力が変化する場合には、受電装置２０は一定のセンサ出力の変化を無視する構成としてもよい。例えば、車両側制御部１０１は、車両１０のドアの開閉センサから検出信号を入力し、且つ、この検出信号に基づきドアの開閉から所定期間だけステップＳ２１２の判別処理で使用する閾値を大きく設定変更する構成とする。このように構成することで、受電装置２０は、ドアの開閉や運転手の昇降によるセンサ出力の変化を無視することができる。さらに、加速度センサ１０９の感度および検出精度が非常に高くて、加速度の検出から車両１０の移動量が正確に算出できるような場合には、車両側制御部１０１は加速度の検出出力から充電操作後の車両１０の移動量を算出する構成としてもよい。そして、車両側制御部１０１は、算出した移動量に基づいて給電を停止させる制御を行う構成としてもよい。   Note that when the sensor output changes due to a small vibration or the like in which the acceleration sensor 109 has high sensitivity and the vehicle 10 does not move at all, the power receiving device 20 may be configured to ignore a certain change in the sensor output. . For example, the vehicle-side control unit 101 inputs a detection signal from a door opening / closing sensor of the vehicle 10, and greatly changes the threshold value used in the determination processing in step S <b> 212 for a predetermined period from the door opening / closing based on the detection signal. The configuration is as follows. With this configuration, the power receiving device 20 can ignore changes in the sensor output due to opening / closing of the door and raising / lowering of the driver. Furthermore, when the sensitivity and detection accuracy of the acceleration sensor 109 are very high, and the amount of movement of the vehicle 10 can be accurately calculated from the acceleration detection, the vehicle-side control unit 101 uses the acceleration detection output after the charging operation. It is good also as a structure which calculates the moving amount | distance of the vehicle 10 of this. And the vehicle side control part 101 is good also as a structure which performs control which stops electric power feeding based on the calculated movement amount.

（実施の形態４）
図８は、実施の形態４の充電手順を説明するフローチャートである。この実施の形態４の車両用電力供給システムは、実施の形態３と構成が同一である。また、受電装置２０の動作の一部は、実施の形態２および実施の形態３のものと同一であり、給電装置３０の動作は、実施の形態３のものと同一である。図８の処理ステップにおいて、実施の形態２，３の処理ステップと同じ処理ステップは、同一符号を付して詳細な説明を省略する。 (Embodiment 4)
FIG. 8 is a flowchart for explaining the charging procedure of the fourth embodiment. The vehicle power supply system of the fourth embodiment has the same configuration as that of the third embodiment. Part of the operation of power reception device 20 is the same as that of the second and third embodiments, and the operation of power supply device 30 is the same as that of the third embodiment. In the processing steps of FIG. 8, the same processing steps as those of the second and third embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

実施の形態４では、実施の形態３と同様に、図８のステップＳ２０１，Ｓ２０２，Ｓ２０９，Ｓ２１０の処理が行われて、ステップＳ２１１〜Ｓ２１３の処理ループに移行する。そして、この処理ループの中で車両側制御部１０１が充電完了と判別すると、ステップＳ２０６で給電停止要求が給電装置３０へ送られて給電が停止される。   In the fourth embodiment, similarly to the third embodiment, the processes in steps S201, S202, S209, and S210 in FIG. 8 are performed, and the process shifts to the process loop in steps S211 to S213. When the vehicle-side control unit 101 determines that charging is completed in this processing loop, a power supply stop request is sent to the power supply apparatus 30 in step S206 to stop power supply.

実施の形態４では、ステップＳ２１１，Ｓ２１３の処理ループ中、車両側制御部１０１が加速度変化を検出して処理ループを抜けると、車両側制御部１０１は、動き検知情報を車両側通信部１０４を介して給電装置３０へ送信する（ステップＳ２０７）。この動き検知情報は、受電部１０３と給電部１０６との位置ズレが給電動作の許容誤差を超える可能性があることを示す情報となる。   In the fourth embodiment, during the processing loop of steps S211, S213, when the vehicle-side control unit 101 detects a change in acceleration and exits the processing loop, the vehicle-side control unit 101 sends the motion detection information to the vehicle-side communication unit 104. To the power supply apparatus 30 (step S207). This motion detection information is information indicating that the positional deviation between the power reception unit 103 and the power supply unit 106 may exceed the allowable error of the power supply operation.

動き検知情報が送信されると、給電側制御部１０７は、図４のフローチャートで説明したように、給電側通信部１０５を介してこの情報を受信する。そして、この動き検知情報に基づいて、給電側制御部１０７は、給電部１０６を制御して給電を停止させる。   When the motion detection information is transmitted, the power supply side control unit 107 receives this information via the power supply side communication unit 105 as described in the flowchart of FIG. And based on this motion detection information, the electric power feeding side control part 107 controls the electric power feeding part 106, and stops electric power feeding.

この実施の形態４の受電装置２０によれば、給電中、車両側制御部１０１は、加速度センサ１０９の出力を監視し、加速度変化があった場合に、動き検知情報を給電装置３０へ送信する。また、この実施の形態４の給電装置３０によれば、給電中、給電側制御部１０７は、上記の動き検知情報の受信の有無を監視し、この受信があった場合に、給電を停止させる。従って、この車両用電力供給システムにおいては、給電中に受電部１０３と給電部１０６との間に位置ずれが生じた場合でも、漏洩磁界および不要輻射が増大するような異常な給電状態になることが防止される。   According to the power receiving device 20 of the fourth embodiment, during power feeding, the vehicle-side control unit 101 monitors the output of the acceleration sensor 109 and transmits motion detection information to the power feeding device 30 when there is a change in acceleration. . Further, according to the power feeding device 30 of the fourth embodiment, during power feeding, the power feeding side control unit 107 monitors whether or not the motion detection information is received, and stops power feeding when the motion detection information is received. . Therefore, in this vehicle power supply system, even if a position shift occurs between the power receiving unit 103 and the power supply unit 106 during power supply, an abnormal power supply state in which leakage magnetic field and unnecessary radiation increase is caused. Is prevented.

なお、各実施の形態では、受電装置が車輪速センサ１０８または加速度センサ１０９の出力に基づき車両１０の動きを検出するようにしているが、受電装置は両者の検出を併用して車両１０の小さな動きをより精度高く検出する構成としてもよい。また、受電装置は反射型のフォトセンサ（フォトリフレクタ）を用いて、給電装置３０と車両１０との相対位置の変化を検出する構成としてもよい。   In each embodiment, the power receiving device detects the movement of the vehicle 10 based on the output of the wheel speed sensor 108 or the acceleration sensor 109. However, the power receiving device uses both detections in combination to detect the small size of the vehicle 10. It is good also as a structure which detects a motion more accurately. In addition, the power receiving device may be configured to detect a change in the relative position between the power feeding device 30 and the vehicle 10 using a reflective photosensor (photo reflector).

また、各実施の形態において、非接触で送電を行う構成は、給電コイルと受電コイルとを用いた電磁誘導方式の構成としている。しかしながら、この非接触で送電を行う構成は、給電中に受電部と給電部との位置が正確に合っている必要のある構成であれば、どのような方式の構成であってもよい。このような構成であれば、本発明は有効に適用できる。   Moreover, in each embodiment, the structure which performs non-contact power transmission is an electromagnetic induction type structure using a power feeding coil and a power receiving coil. However, this non-contact power transmission configuration may be any type of configuration as long as the power receiving unit and the power feeding unit need to be accurately positioned during power feeding. With such a configuration, the present invention can be effectively applied.

また、上記実施の形態では、本発明をハードウェアと制御部によるソフトウェアとの連携により実現する構成を例にとって説明したが、ソフトウェアにより実現した部分はハードウェアによって実現することも可能である。   In the above-described embodiment, the configuration in which the present invention is realized by cooperation between hardware and software by the control unit has been described as an example. However, the part realized by software can also be realized by hardware.

本発明は、電気で走行する車両に搭載されて外部から非接触で受電を行う受電装置、および、給電を行う給電装置に有用である。   INDUSTRIAL APPLICABILITY The present invention is useful for a power receiving device that is mounted on a vehicle that runs on electricity and receives power from the outside without contact, and a power feeding device that supplies power.
