本発明の非接触給電装置は、駐車スペースに設置した給電部と、車両に搭載した受電部との磁気的結合によって、車両に対して非接触で電力供給を行う構成を基本としている。   The non-contact power supply apparatus of the present invention is basically configured to supply power to a vehicle in a non-contact manner by magnetic coupling between a power supply unit installed in a parking space and a power receiving unit mounted on the vehicle.

そして、前記非接触給電装置は、前記駐車スペースに設けられて、該駐車スペースへの前記車両の移動を誘導して、前記給電部に対して受電部が正対可能な位置に駐車位置を規制する駐車誘導規制手段と、この駐車誘導規制手段に車幅方向に対向して配設した投光器と受光器とを備えて、前記駐車スペースに駐車した前記車両の車輪がこれら投光器と受光器との間に移動して投光が遮断されることにより、車両の前後方向のずれ動きを検出する光電センサと、を備えたことを主要な特徴としている。   And the said non-contact electric power feeder is provided in the said parking space, guide | induces the movement of the said vehicle to this parking space, and regulates a parking position to the position where a power receiving part can face with respect to the said electric power feeding part.

以下、本発明の一実施形態を図面と共に詳述する。   Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

図１に示す本実施形態の非接触給電装置は、地上側ユニットである給電装置１００と、車両側ユニットである受電装置２００と、を備え、給電スタンド等に設置される給電装置１００から、電気自動車やハイブリッド車に代表される車両１に搭載された受電装置２００に非接触で電力を供給し、車載バッテリ２７を充電するものである。   The non-contact power feeding device of the present embodiment shown in FIG. 1 includes a power feeding device 100 that is a ground side unit and a power receiving device 200 that is a vehicle side unit. Electric power is supplied in a non-contact manner to a power receiving device 200 mounted on a vehicle 1 typified by an automobile or a hybrid vehicle, and the vehicle battery 27 is charged.

給電装置１００は、給電スタンド近傍の駐車スペース２に設置した給電部１２を備え、受電装置２００は、車両１を駐車スペース２の所定位置に止めたときに給電部１２（図２参照）に対向するように車両１の底面に配設した受電部２２を備えている。   The power feeding device 100 includes a power feeding unit 12 installed in the parking space 2 near the power feeding stand, and the power receiving device 200 faces the power feeding unit 12 (see FIG. 2) when the vehicle 1 is stopped at a predetermined position in the parking space 2. Thus, a power receiving unit 22 disposed on the bottom surface of the vehicle 1 is provided.

図２に示すように、駐車スペース２には給電部１２を中央にして駐車誘導規制手段３を配設して、駐車スペース２への車両１の移動を誘導して、給電部１２に対して受電部２２が正対可能な位置に駐車位置を規制するようにしている。   As shown in FIG. 2, the parking space 2 is provided with parking guidance restricting means 3 with the power feeding unit 12 at the center to guide the movement of the vehicle 1 to the parking space 2. The parking position is restricted to a position where the power receiving unit 22 can be directly opposed.

本実施形態では、駐車誘導規制手段３として、車両１を後退して駐車スペース２に進入させた際に、後輪（車輪）Ｗを車幅方向に位置規制する所要高さの一対の縁石４と、駐車スペース２の奥側に設けた車止め５と、で構成している。   In the present embodiment, as the parking guidance regulating means 3, when the vehicle 1 is moved backward and entered the parking space 2, a pair of curbs 4 having a required height that regulates the position of the rear wheel (wheel) W in the vehicle width direction. And a car stop 5 provided on the back side of the parking space 2.

縁石４は、左右の後輪Ｗの離間幅よりも幾分広い離間間隔をおいて車両前後方向に延在配置して、後輪Ｗのみの後退移動を誘導し得る適宜の長さに設定してある。   The curbstone 4 is arranged to extend in the vehicle front-rear direction with a spacing that is slightly wider than the spacing between the left and right rear wheels W, and is set to an appropriate length that can guide the backward movement of only the rear wheels W. It is.

車止め５は、この縁石４と一体もしくは別体に設けられ、車両１を後退移動して受電部２２の中心と給電部１２の中心が前後方向にほぼ揃う後退位置で、後輪Ｗを受け止めて後退規制し得る位置に設定してある。   The car stopper 5 is provided integrally with or separately from the curbstone 4, and moves the vehicle 1 backward so that the center of the power receiving unit 22 and the center of the power feeding unit 12 are substantially aligned in the front-rear direction and receives the rear wheel W. It is set at a position where it can be controlled to reverse.

これにより、車両１を駐車スペース２に後退移動する際に、後輪Ｗを左右の縁石４に沿って後退させて車幅方向の位置規制を行い、そして、後輪Ｗが車止め５に当接した位置で停止することによって、車両１側の受電部２２を地上側の給電部１２に正対もしくはほぼ正対させることができる。   As a result, when the vehicle 1 moves backward to the parking space 2, the rear wheel W is moved backward along the left and right curbs 4 to restrict the position in the vehicle width direction, and the rear wheel W comes into contact with the vehicle stop 5. By stopping at the position, the power receiving unit 22 on the vehicle 1 side can be directly or almost directly opposed to the power supply unit 12 on the ground side.

従って、上述の左右一対の縁石４の車幅方向の離間幅は、後輪Ｗとの間隙が給電部１２に対する受電部２２の所要のずれ許容範囲内となるように設定される。   Therefore, the separation width in the vehicle width direction of the pair of left and right curbs 4 is set such that the gap with the rear wheel W is within a required deviation allowable range of the power receiving unit 22 with respect to the power feeding unit 12.

そして、これら左右の縁石４に、駐車スペース２の所定位置、即ち、給電部１２に対して受電部２２がほぼ正対する位置に駐車した車両１の前後方向のずれ動きを検出する光電センサ６を設けてある。   And the photoelectric sensor 6 which detects the shift | offset | difference movement of the front-back direction of the vehicle 1 parked in the predetermined position of the parking space 2, ie, the position where the power receiving part 22 is substantially opposite to the power feeding part 12, is provided on the left and right curbs 4. It is provided.

光電センサ６は、投光器６Ａと受光器６Ｂとを備えて、駐車スペース２に駐車した車両１の車輪、即ち、本実施形態では後輪Ｗがこれら投光器６Ａと受光器６Ｂとの間に移動して投光Ｌが遮断されることにより、これを電気信号に変換して検出するものである。   The photoelectric sensor 6 includes a light projector 6A and a light receiver 6B, and the wheel of the vehicle 1 parked in the parking space 2, that is, the rear wheel W in this embodiment moves between the light projector 6A and the light receiver 6B. When the light projection L is blocked, this is converted into an electric signal and detected.

従って、本実施形態では上述の光電センサ６の投光器６Ａと受光器６Ｂとを、左右の縁石４の駐車スペース入口側の端部で、駐車車両１の駐車スペース入口側に面した後輪Ｗの前側近傍に投光Ｌが配光可能な位置に設けている。   Accordingly, in the present embodiment, the light projector 6A and the light receiver 6B of the photoelectric sensor 6 described above are arranged at the end of the left and right curb 4 on the parking space entrance side of the rear wheel W facing the parking space entrance side of the parked vehicle 1. It is provided at a position where the light projection L can be distributed near the front side.

また、本実施形態では、上述の左右一対の車止め５に、投光器７Ａと受光器７Ｂとを備

Further, during power feeding, the power feeding is stopped based on the detection signals from the photoelectric sensors 6 and 7 described above, or a warning signal is transmitted to the vehicle 1 side through the wireless communication units 13 and 23.

車両１側の受電装置２００は、受電コイル２２と、無線通信部２３と、充電制御部２４と、整流部２５と、リレー部２６と、バッテリ２７と、インバータ２８と、モータ３０と、通知部３２と、を備えている。   The power receiving device 200 on the vehicle 1 side includes a power receiving coil 22, a wireless communication unit 23, a charging control unit 24, a rectifying unit 25, a relay unit 26, a battery 27, an inverter 28, a motor 30, and a notification unit. 32.

受電コイル２２は、上述のように車両１の底面（シャシ）等で、左右の後輪Ｗ間に設けられ、上述のように駐車誘導規制手段３により車両１が駐車スペース２の所定位置に誘導，規制されて駐車すると、送電コイル１２の直上に正対し、該送電コイル１２と距離を保って位置づけられる。   The power receiving coil 22 is provided between the left and right rear wheels W on the bottom surface (chassis) of the vehicle 1 as described above, and the vehicle 1 is guided to a predetermined position in the parking space 2 by the parking guidance restricting means 3 as described above. When the vehicle is regulated and parked, it faces directly above the power transmission coil 12 and is positioned at a distance from the power transmission coil 12.

整流部２５は、受電コイル２２に接続され、受電コイル２２で受電された交流電力を直流に整流する整流回路により構成されている。   The rectification unit 25 is connected to the power reception coil 22 and is configured by a rectification circuit that rectifies AC power received by the power reception coil 22 into direct current.

リレー部２６は、充電制御部２４の制御によりオンおよびオフが切り換わるリレースイッチを備えている。また、リレー部２６は、リレースイッチをオフにすることで、バッテリ２７を含む強電系と、充電の回路部となる受電コイル２２および整流部２５の弱電系とを切り離す。   The relay unit 26 includes a relay switch that is switched on and off under the control of the charging control unit 24. Moreover, the relay part 26 isolate | separates the strong electric system containing the battery 27, and the receiving coil 22 used as the circuit part of charge, and the weak electric system of the rectification | straightening part 25 by turning off a relay switch.

バッテリ２７は、複数の二次電池を接続することで構成され、車両１の電力源となる。インバータ２８は、ＩＧＢＴ等のスイッチング素子を有したＰＷＭ制御回路等の制御回路であって、スイッチング制御信号にもとづいて、バッテリ２７から出力される直流電力を交流電力にし、モータ２９に供給する。モータ２９は、例えば三相の交流電動機により構成され、車両１を駆動させるための駆動源となる。   The battery 27 is configured by connecting a plurality of secondary batteries, and serves as a power source for the vehicle 1. The inverter 28 is a control circuit such as a PWM control circuit having a switching element such as an IGBT, and based on the switching control signal, the DC power output from the battery 27 is converted into AC power and supplied to the motor 29. The motor 29 is composed of, for example, a three-phase AC motor and serves as a drive source for driving the vehicle 1.

通知部３０は、警告ランプ、ナビゲーションシステムのディスプレイまたはスピーカ等により構成され、充電制御部２４による制御にもとづいて、ユーザに対して光、画像または音声等を出力する。   The notification unit 30 is configured by a warning lamp, a display of a navigation system, a speaker, or the like, and outputs light, an image, a sound, or the like to the user based on control by the charging control unit 24.

充電制御部２４は、バッテリ２７の充電を制御するためのコントローラであり、無線通信部２３、通知部３０、リレー部２６等を制御する。充電制御部２４は、充電を開始する旨の信号を、無線通信部２３，１３の通信により制御部１４に送信する。また、充電制御部２４は、車両１の全体を制御する図外のコントローラとＣＡＮ通信網で接続されている。このコントローラは、インバータ２８のスイッチング制御や、バッテリ２７の充電状態（ＳＯＣ）を管理する。そして、充電制御部２４は、このコントローラにより、バッテリ２７の充電状態にもとづいて満充電に達した場合に、充電を終了する旨の信号を制御部１４に送信する。   The charging control unit 24 is a controller for controlling the charging of the battery 27, and controls the wireless communication unit 23, the notification unit 30, the relay unit 26, and the like. The charging control unit 24 transmits a signal to start charging to the control unit 14 through communication of the wireless communication units 23 and 13. The charging control unit 24 is connected to a controller (not shown) that controls the entire vehicle 1 through a CAN communication network. This controller manages the switching control of the inverter 28 and the state of charge (SOC) of the battery 27. Then, when the controller reaches the full charge based on the charge state of the battery 27, the charge control unit 24 transmits a signal to the control unit 14 to end the charge.

従って、本実施形態の非接触給電装置では、送電コイル１２と受電コイル２２との間で、電磁誘導作用により非接触状態で高周波電力の送電および受電を行う。言い換えると、送電コイル１２に電圧が加わると、送電コイル１２と受電コイル２２との間には磁気的な結合が生じ、送電コイル１２から受電コイル２２へ電力が供給される。   Therefore, in the non-contact power feeding device of the present embodiment, high-frequency power is transmitted and received between the power transmission coil 12 and the power receiving coil 22 in a non-contact state by electromagnetic induction action. In other words, when a voltage is applied to the power transmission coil 12, magnetic coupling occurs between the power transmission coil 12 and the power reception coil 22, and power is supplied from the power transmission coil 12 to the power reception coil 22.

以上の構成からなる本実施形態の非接触給電装置によれば、駐車誘導規制手段３により駐車スペース２への車両１の移動を誘導して、駐車スペース２側の送電コイル１２に対して車両１側の受電コイル２２が正対可能な位置に駐車位置を規制することができる。   According to the contactless power supply device of the present embodiment having the above-described configuration, the vehicle 1 is guided to the parking space 2 by the parking guidance restricting means 3, and the vehicle 1 is compared with the power transmission coil 12 on the parking space 2 side. The parking position can be restricted to a position where the power receiving coil 22 on the side can be directly opposed.

このため、運転者の運転操作技量の如何にかかわらず車両１を適正な給電ポイントに駐車させることができる。   For this reason, the vehicle 1 can be parked at an appropriate feeding point regardless of the driving skill of the driver.

そして、パーキングブレーキの掛け忘れ等、何等かの理由で給電中に車両１が前後方向、例えば、駐車スペース２の入口側にずれ動いた場合には、後輪Ｗが光電センサ６の投光Ｌを遮ることで、つまり、車輪の挙動をもって速やかに検出することができる。   If the vehicle 1 moves in the front-rear direction, for example, toward the entrance side of the parking space 2 during power feeding for some reason, such as forgetting to apply the parking brake, the rear wheel W emits light L of the photoelectric sensor 6. , That is, it can be detected quickly with the behavior of the wheel.

これにより、制御部１４により直ちに警告あるいは給電停止を促して給電不良を誘発するのを回避することができる。   As a result, it is possible to avoid inducing power supply failure by prompting the control unit 14 to immediately warn or stop power supply.

ここで、本実施形態では上述の駐車誘導規制手段３として、駐車スペース２に対して進入側となる車両１の後輪Ｗを車幅方向に位置規制する所要高さの左右一対の縁石４と、駐車スペース３の奥側に縁石４と一体もしくは別体に設けた一対の車止め５と、で構成している。   Here, in the present embodiment, as the above-described parking guidance restriction means 3, a pair of left and right curb stones 4 of a required height for restricting the position of the rear wheel W of the vehicle 1 on the entry side with respect to the parking space 2 in the vehicle width direction; , And a pair of car stops 5 provided integrally with or separately from the curb 4 on the back side of the parking space 3.

これにより、車両１を駐車スペース２へ後退移動させる際に、後輪Ｗが縁石４に接触することで運転者は車両１の車幅方向位置を容易に知覚できる。従って、初心者でも容易に適正な給電ポイントへと誘導して駐車規制することが可能となり、特にリヤビューモニターやアラウンドビューモニター等の撮像機器を搭載していない車両であっても容易に給電ポイントへ後退誘導させることができる。   Accordingly, when the vehicle 1 is moved backward to the parking space 2, the driver can easily perceive the position in the vehicle width direction of the vehicle 1 by the rear wheel W coming into contact with the curb 4. Therefore, even beginners can easily guide parking to an appropriate power supply point and control parking, and even if the vehicle is not equipped with an imaging device such as a rear view monitor or an around view monitor, it can easily retreat to the power supply point. Can be induced.

また、縁石４は給電コイル１２と受電コイル２２とが正対する給電ポイントに近い後輪Ｗのみの後退移動を誘導し得る前後長さとしていることからも、上述の給電ポイントへの後退移動をより容易に行うことができる。   Further, the curb 4 has a longitudinal length that can induce the backward movement of only the rear wheel W close to the feeding point where the feeding coil 12 and the receiving coil 22 face each other. It can be done easily.

そして、縁石４および車止め５を用いることにより、これら縁石４と車止め５および車両１のフロア下面とで給電コイル１２の周辺を囲んで、給電コイル１２と受電コイル２２とで形成される磁場への異物の侵入を抑制することができる。   Then, by using the curb 4 and the car stopper 5, the curb 4, the car stopper 5, and the lower surface of the floor of the vehicle 1 surround the periphery of the power feeding coil 12, and the magnetic field formed by the power feeding coil 12 and the power receiving coil 22 is applied. Intrusion of foreign matter can be suppressed.

特に、光電センサ６の投光器６Ａと受光器６Ｂを、左右の縁石４の駐車スペース入口側の端部で、駐車車両１の駐車スペース入口側に面した後輪Ｗの前側近傍に投光Ｌを配光可能な位置に設けることにより、該光電センサ６により駐車スペース入口側からの異物侵入の検出も行え、警告あるいは給電停止を促すことができる利点がある。   In particular, the light projector 6A and the light receiver 6B of the photoelectric sensor 6 are projected near the front side of the rear wheel W facing the parking space entrance side of the parked vehicle 1 at the end of the left and right curb 4 on the parking space entrance side. By providing it at a position where light can be distributed, there is an advantage that the photoelectric sensor 6 can detect entry of foreign matter from the entrance side of the parking space, and can prompt a warning or stop power supply.

また、本実施形態では一対の車止め５に、投光器７Ａと受光器７Ｂとを備えて、これら両者間で投光Ｌが遮断されることにより給電コイル１２側への異物の侵入を検出する光電センサ７を配設してあるので、上述の磁場への異物侵入検出を徹底することができる。   In the present embodiment, the pair of car stops 5 includes a light projector 7A and a light receiver 7B, and the photoelectric sensor that detects the intrusion of foreign matter to the power feeding coil 12 side by blocking the light projection L between them. Since 7 is disposed, it is possible to thoroughly detect the intrusion of foreign matter into the magnetic field described above.
