The non-contact power supply control device, limits feeding power supplied to the vehicle-side reception section 11 as compared to in the case that the presence of an organism is not detected, when the presence of an organism is detected in the vicinity to the ground-side power feeding section 111 during power feeding operation into the vehicle-side reception section 11.

Description

本発明は、外部の電源から車両の電池に非接触で電力を給電する非接触給電制御装置及び当該制御装置を備える非接触給電システムに関する。   The present invention relates to a non-contact power supply control device that supplies electric power to a battery of a vehicle from an external power source in a non-contact manner and a non-contact power supply system including the control device.

近年、環境に配慮した車両として、電気自動車、ハイブリッド車等の電動の車両が注目されている。これらの電動車両には、走行用の電力を外部電源からの充電を可能とする電池が装備されている。充電用の電力を給電する方法としては、給電側の電源口と車両の充電口とをケーブルで接続するプラグイン式の給電方法や、ケーブルを用いない非接触式の給電方法が知られている。   In recent years, electric vehicles such as electric vehicles and hybrid vehicles have attracted attention as environmentally friendly vehicles. These electric vehicles are equipped with a battery that enables charging of electric power for traveling from an external power source. As a method of supplying power for charging, a plug-in type power supply method in which a power supply port on the power supply side and a charging port of a vehicle are connected with a cable, and a non-contact type power supply method without using a cable are known. .

非接触式の給電方法に関する従来技術として、例えば、特許文献１に記載の非接触給電システムがある。この従来技術では、一次側コイルと二次側コイル間で電磁場を介して送電が行われる。特許文献１の非接触給電システムでは、外部の施設に装備された交流電源からの電力を高周波電力ドライバによって高周波の電力に変換した後、一次側コイルへ供給する。そして、車体下部に配設される二次側コイルは、電磁結合により電流が流れることによって、対向する一次側コイルからの給電を受ける。   As a conventional technique related to a non-contact power supply method, for example, there is a non-contact power supply system described in Patent Document 1. In this prior art, power transmission is performed via an electromagnetic field between a primary side coil and a secondary side coil. In the non-contact power supply system of Patent Document 1, power from an AC power source installed in an external facility is converted into high-frequency power by a high-frequency power driver and then supplied to the primary coil. And the secondary side coil arrange | positioned by the vehicle body lower part receives the electric power feeding from the opposing primary side coil, when an electric current flows by electromagnetic coupling.

特開２０１０−９３９５７号公報JP 2010-93957 A

上記従来技術では、上記のように地面近傍に配された一次側コイルと車体下部に配された二次側コイルとの間で電磁場を介して電力が伝送されるため、給電動作中に、一次側コイル付近や二次側コイル付近に人が存在すると、存在する人体が電磁界の影響を受けるという問題がある。   In the above prior art, power is transmitted through the electromagnetic field between the primary coil disposed near the ground as described above and the secondary coil disposed in the lower part of the vehicle body. When a person is present near the side coil or the secondary coil, there is a problem that the existing human body is affected by the electromagnetic field.

具体的には、上記従来技術では、車両のドアが施錠されると充電開始要求信号を車両外部装置に送信して充電運転を開始する。このようなタイミングで充電運転が開始すると、まだ車両近傍に人がいる可能性があり、人体は電磁界の影響を受け得る。   Specifically, in the above prior art, when the vehicle door is locked, a charging start request signal is transmitted to the vehicle external device to start the charging operation.

コーナーセンサＥＣＵ７は、車両１のバンパ等の数箇所に埋設されるセンサ７１，７２，７３，７４から入力される反射波の電気信号を用いて車両１周辺に生体が存在するか否かを判定する。図７は第２の生体検知手段として用いられるコーナーセンサの検知範囲を説明するための車両平面図であり、各センサ７１〜７４は、図示するように車両１の周辺にそれぞれ検知範囲Ｄ２を有する。各センサ７１〜７４は、車両１周辺に向けて所定の光または音波を発信する発信部と、その反射波を受信する受信部と、を含む手段であり、例えば超音波を発信及び受信可能な超音波センサで構成することができる。各センサ７１〜７４の動作は、コーナーセンサＥＣＵ７によって制御される。   The corner sensor ECU 7 determines whether or not a living body is present around the vehicle 1 using electric signals of reflected waves input from sensors 71, 72, 73, and 74 embedded in several locations such as a bumper of the vehicle 1. To do. FIG. 7 is a plan view of the vehicle for explaining the detection range of the corner sensor used as the second living body detection means, and each sensor 71 to 74 has a detection range D2 around the vehicle 1 as shown. . Each of the sensors 71 to 74 is a means including a transmitting unit that transmits predetermined light or sound waves toward the periphery of the vehicle 1 and a receiving unit that receives the reflected waves, and can transmit and receive ultrasonic waves, for example. An ultrasonic sensor can be used. The operations of the sensors 71 to 74 are controlled by the corner sensor ECU 7.

つまり、各センサ７１〜７４は、所定の検知範囲Ｄ２に生体が入った場合に、生体からの反射波を受信する。コーナーセンサＥＣＵ７は、生体が入る前に受信した反射波に対応する電気信号と生体からの反射波に対応する電気信号との違いに基づいて、生体の存否を判定する。   That is, each sensor 71 to 74 receives a reflected wave from the living body when the living body enters the predetermined detection range D2. The corner sensor ECU 7 determines the presence or absence of the living body based on the difference between the electrical signal corresponding to the reflected wave received before the living body enters and the electrical signal corresponding to the reflected wave from the living body.

この第２の生体検知手段によれば、車両１が有するセンサ７１〜７４を活用した生体検知により、各センサ７１〜７４が有する検知範囲に応じた生体検知を可能とし、センサを搭載する車両１に対しては部品点数の増加の低減が図れる非接触給電システムを提供できる。   According to the second living body detection means, the living body detection utilizing the sensors 71 to 74 of the vehicle 1 enables the living body detection according to the detection range of the sensors 71 to 74, and the vehicle 1 on which the sensors are mounted. Therefore, it is possible to provide a non-contact power feeding system that can reduce the increase in the number of parts.

スマートＥＣＵ８は、車両１のドア部等の数箇所に埋設される送受信機８１から入力される所定の電気信号を用いて車両１周辺に生体が存在するか否かを判定する。図９は第３の生体検知手段として用いられるスマートエントリーの車両側送受信機の検知範囲を説明するための車両平面図であり、各送受信機８１は、図示するように車両１の周辺にそれぞれ検知範囲Ｄ３を有する。送受信機８１が受信する所定の電気信号は、本車両１に固有に設定されたスマートエントリーキーが有する固有管理番号（ＩＤ番号ともいう）に対応する電気信号である。   The smart ECU 8 determines whether a living body is present around the vehicle 1 using predetermined electrical signals input from a transceiver 81 embedded in several places such as a door portion of the vehicle 1. FIG. 9 is a plan view of the vehicle for explaining the detection range of the smart-entry vehicle-side transceiver used as the third living body detection means. Each transceiver 81 is detected around the vehicle 1 as shown in the figure. It has a range D3. The predetermined electrical signal received by the transceiver 81 is an electrical signal corresponding to a unique management number (also referred to as an ID number) possessed by a smart entry key that is uniquely set for the vehicle 1.

つまり、送受信機８１は、車両１のユーザーが当該固有管理番号を有するスマートエントリーキーを所持している場合に、ユーザーが所定の検知範囲Ｄ３に入ったときに、当該固有管理番号に対応する電気信号を受信する。スマートＥＣＵ８は、送受信機８１によって受信された固有管理番号が本車両１に固有に設定された固有管理番号であるか否かを判定し、一致するときはキー照合がなされたとして当該スマートエントリーキーを所持する者が車両１の周辺に存在すると判定する。スマートＥＣＵ８は、このようにして生体の存否を判定する。   That is, when the user of the vehicle 1 has a smart entry key having the unique management number and the user enters the predetermined detection range D3, the transmitter / receiver 81 has an electric power corresponding to the unique management number. Receive a signal. The smart ECU 8 determines whether or not the unique management number received by the transmitter / receiver 81 is a unique management number set uniquely for the vehicle 1. It is determined that the person who possesses the vehicle 1 exists around the vehicle 1. The smart ECU 8 determines the presence or absence of a living body in this way.

この第３の生体検知手段によれば、スマートエントリーキーを所持する人がドア等に触れてドアの開錠または施錠の動作をする前に、車両周辺に人が存在することを検知して車両１に人が近づいたことを検出できる。したがって、生体が車両１の傍からある程度離れた状態で電力制限を伴う給電運転を実施することが可能である。また、車両が有する、例えばスマートエントリーキー（携帯送信機）を活用した生体検知により、受信機側の検知範囲に応じた生体検知を可能とし、このような携帯送信機によるドア開閉指令手段を採用する車両１に対しては部品点数増加の低減が図れる非接触給電システムを提供できる。   According to the third living body detection means, the person who has the smart entry key touches the door or the like to detect the presence of a person around the vehicle before unlocking or locking the door. It is possible to detect that a person has approached 1. Therefore, it is possible to carry out a power feeding operation with power limitation in a state where the living body is separated from the side of the vehicle 1 to some extent. In addition, biometric detection using a smart entry key (portable transmitter), for example, in a vehicle enables biometric detection according to the detection range on the receiver side, and door opening / closing command means using such a portable transmitter is adopted. Thus, a contactless power feeding system that can reduce the increase in the number of components can be provided for the vehicle 1 that performs the above operation.

車両制御ＥＣＵ９は、第４の生体検知手段として、位置検出機能を有する携帯電話機等の携帯機器１２０が車両１に近づいた場合に、当該機能を用いた携帯機器１２０の端末位置情報と車両１の位置情報とを照合する。車両制御ＥＣＵ９は、この位置情報の照合によって、端末位置が車両１周辺の所定の範囲内にあるか否かを判定する。車両制御ＥＣＵ９は、取得した端末位置が車両１周辺の所定の範囲内にあると判定したときは、位置検出機能を有する携帯機器１２０を所持する者が車両１の周辺に存在すると判定する。車両制御ＥＣＵ９は、このようにして生体の存否を判定する。   When the mobile device 120 such as a mobile phone having a position detection function approaches the vehicle 1 as the fourth living body detection means, the vehicle control ECU 9 detects the terminal position information of the mobile device 120 using the function and the vehicle 1. Collate with location information. The vehicle control ECU 9 determines whether or not the terminal position is within a predetermined range around the vehicle 1 by checking the position information. When the vehicle control ECU 9 determines that the acquired terminal position is within a predetermined range around the vehicle 1, the vehicle control ECU 9 determines that a person having the portable device 120 having the position detection function exists around the vehicle 1. The vehicle control ECU 9 determines the presence or absence of a living body in this way.

なお、車両１の位置検出機能及び携帯機器１２０の位置検出機能としては、例えば、衛生測位システムであるグローバル・ポジショニング・システム（Global Positioning System）を使用することができる。当該衛生測位システムと車両制御ＥＣＵ９は、車両位置検出手段及び携帯機器１２０の端末位置検出手段を構成する。   In addition, as a position detection function of the vehicle 1 and a position detection function of the portable device 120, for example, a global positioning system (Global Positioning System) that is a sanitary positioning system can be used. The sanitary positioning system and the vehicle control ECU 9 constitute vehicle position detection means and terminal position detection means of the portable device 120.

この第４の生体検知手段によれば、携帯電話機等の携帯機器１２０が備える位置検出機能と車両１の位置を検出する位置検出機能とを活用した生体検知により、携帯機器１２０を所持する人が車両周辺に存在することを検知して、車両１に当該人が近づいたことを検出できる。したがって、生体が車両１の傍からある程度離れた状態で電力制限を伴う給電運転を実施することが可能である。   According to the fourth living body detection means, a person who holds the portable device 120 can detect a living body using the position detection function of the portable device 120 such as a mobile phone and the position detection function of detecting the position of the vehicle 1. It can be detected that the person is approaching the vehicle 1 by detecting that the vehicle is present around the vehicle. Therefore, it is possible to carry out a power feeding operation with power limitation in a state where the living body is separated from the side of the vehicle 1 to some extent.

車両制御ＥＣＵ９は、各種センサからの信号によって運転状態に応じたエンジン出力及びモータのトルクを算出し、各ＥＣＵに要求値を出力して駆動輪２３の駆動力を制御する。エンジンＥＣＵ２は、車両制御ＥＣＵ９からのエンジン出力要求に従い、電子スロットルを制御してエンジン２０の動力を制御する。モータジェネレータＥＣＵ４は、車両制御ＥＣＵ９からの信号により、第１モータジェネレータ４１、第２モータジェネレータ４２、第１インバータ４３、第２インバータ４４、及び昇圧コンバータ３１を制御する。   The vehicle control ECU 9 calculates engine output and motor torque according to the driving state based on signals from various sensors, and outputs required values to each ECU to control the driving force of the drive wheels 23. The engine ECU 2 controls the power of the engine 20 by controlling the electronic throttle according to the engine output request from the vehicle control ECU 9. The motor generator ECU 4 controls the first motor generator 41, the second motor generator 42, the first inverter 43, the second inverter 44, and the boost converter 31 based on a signal from the vehicle control ECU 9.

制御回路１０は、整流回路、インバータを含んで構成されており、地上側給電部１１１を介して外部の系統電源等から得られる交流電力を変換して蓄電装置３０に供給する。充電器ＥＣＵ５は、車両側受電部１１への給電要求の有無を判定する手段であり、また蓄電装置３０の充放電を制御する電子制御装置である。   The control circuit 10 is configured to include a rectifier circuit and an inverter, and converts AC power obtained from an external system power supply or the like via the ground side power supply unit 111 and supplies the AC power to the power storage device 30. The charger ECU 5 is a means for determining whether or not there is a power supply request to the vehicle-side power receiving unit 11, and is an electronic control device that controls charging / discharging of the power storage device 30.

当該給電要求は、停車中にユーザー等の操作に基づいた蓄電装置３０への充電要求や、補機類の駆動要求があり、非接触給電の場合には地上側給電部１１１に対して車両側受電部１１が給電可能な範囲に位置することを充電器ＥＣＵ５が判断したときに満たされる。有線による接触給電の場合は、給電器側の給電口と車両１の受電口とがプラグ接続等によってケーブルで接続されており、給電実施に必要なその他の条件が成立していると充電器ＥＣＵ５が判断したときに満たされる。   The power supply request includes a request for charging the power storage device 30 based on an operation by a user or the like while the vehicle is stopped, and a request for driving auxiliary equipment. This is satisfied when the charger ECU 5 determines that the power receiving unit 11 is located in a range where power can be supplied. In the case of wired contact power supply, the power supply port on the power supply side and the power reception port on the vehicle 1 are connected with a cable by plug connection or the like, and if other conditions necessary for power supply are satisfied, the charger ECU 5 Satisfied when judged.

充電器ＥＣＵ５は、車両制御ＥＣＵ９、制御回路１０を介して各種の負荷３３，３４等と通信可能に構成され、車両側の通信機１２を通じて、地上側給電部１１１側の制御回路１１０に設けられた通信機１１２を介して、給電器側の制御回路１１０等と通信する。車両側の通信機１２は、給電器側の通信機１１２や、携帯電話機等の携帯機器１２０と通信可能に構成されている。車両制御ＥＣＵ９は、充電器ＥＣＵ５等を介して制御回路１０を制御することで、蓄電装置３０の充電制御を行い、ナビゲーション装置、エアコン装置、圧縮機等の各種の負荷３３，３４に対して給電処理も行う。   The charger ECU 5 is configured to be able to communicate with various loads 33 and 34 via the vehicle control ECU 9 and the control circuit 10, and is provided in the control circuit 110 on the ground-side power feeding unit 111 side through the vehicle-side communication device 12. The communication device 112 communicates with the control circuit 110 or the like on the power feeder side. The vehicle-side communication device 12 is configured to be able to communicate with a power supply-side communication device 112 and a mobile device 120 such as a mobile phone. The vehicle control ECU 9 controls the control circuit 10 via the charger ECU 5 or the like, thereby controlling the charging of the power storage device 30 and supplying power to various loads 33 and 34 such as a navigation device, an air conditioner device, and a compressor. Processing is also performed.

住宅内の配電盤１０２は、外部の系統電源等の電力を住宅側で使用される機器の負荷１０３，１０４，１０５等に割り振る機能を果たす。この割り振り機能は、住宅用制御装置１００が配電盤１０２を制御することにより行われる。給電器は、通信機１１２を介して住宅外部の車両１における通信機１２と各種情報を通信することができる。   The distribution board 102 in the house fulfills a function of allocating electric power, such as an external system power supply, to the loads 103, 104, 105, etc. of equipment used on the house side. This allocation function is performed by the home control device 100 controlling the switchboard 102. The power feeder can communicate various information with the communication device 12 in the vehicle 1 outside the house via the communication device 112.

車両１は、遊星歯車機構からなる動力分割機構２１を備えている。この動力分割機構２１によって第１モータジェネレータ４１、第２モータジェネレータ４２、及びエンジン２０の動力が分割されるようになっている。   The vehicle 1 includes a power split mechanism 21 including a planetary gear mechanism. The power split mechanism 21 splits the power of the first motor generator 41, the second motor generator 42, and the engine 20.

第１モータジェネレータ４１、エンジン２０、及び第２モータジェネレータ４２は、それぞれ、動力分割機構２１のサンギア、キャリア、リングギアに機械的に連結されている。第２モータジェネレータ４２には、車軸２２を解して駆動輪２３が機械的に連結されている。車軸２２は、エンジン２０及び第２モータジェネレータ４２から出力された動力を駆動輪２３に伝達するための軸である。また、第１モータジェネレータ４１及び第２モータジェネレータ４２のそれぞれには、第１インバータ４３、第２インバータ４４が接続されている。   The first motor generator 41, the engine 20, and the second motor generator 42 are mechanically coupled to the sun gear, carrier, and ring gear of the power split mechanism 21, respectively. The driving wheel 23 is mechanically connected to the second motor generator 42 via the axle 22. The axle 22 is a shaft for transmitting the power output from the engine 20 and the second motor generator 42 to the drive wheels 23. A first inverter 43 and a second inverter 44 are connected to each of the first motor generator 41 and the second motor generator 42.

上記構成において、車両１の各部の作動状態について説明する。車両１は蓄電装置３０が所定のＳＯＣ（state of charge）以下となるまでは蓄電装置３０からの電力供給で動作する第２モータジェネレータ４２のみで走行する。車両１はその後、発進時、ごく低速時、ゆるやかな下り坂走行時等、エンジン効率のよくない場合には、エンジン２０を停止させたまま、蓄電装置３０からの電力供給で動作する第２モータジェネレータ４２のみで走行する。通常走行時には、エンジン２０の動力は２経路に分割し、一方は車軸２２を介して駆動輪２３を駆動し、もう一方は第１モータジェネレータ４１を駆動して発電する。この発電した電力で第１モータジェネレータ４１を駆動することにより、エンジン２０の駆動力をアシストする。車両制御ＥＣＵ９は、最大効率が得られるように動力分割機構２１の分割の割合を制御する。さらに加速時には、蓄電装置３０から電力が供給されて、さらに第２モータジェネレータ４２による駆動力が追加される。   The operation state of each part of the vehicle 1 in the above configuration will be described. The vehicle 1 travels only by the second motor generator 42 that operates by supplying power from the power storage device 30 until the power storage device 30 becomes a predetermined SOC (state of charge) or less. When the engine 1 is not efficient, such as when starting, when traveling at a very low speed, or traveling on a gentle downhill, the second motor that operates by supplying power from the power storage device 30 while the engine 20 is stopped. The vehicle travels only with the generator 42. During normal travel, the power of the engine 20 is divided into two paths, one driving the drive wheels 23 via the axle 22, and the other driving the first motor generator 41 to generate electric power. By driving the first motor generator 41 with the generated electric power, the driving force of the engine 20 is assisted. The vehicle control ECU 9 controls the division ratio of the power split mechanism 21 so that the maximum efficiency is obtained. Further, at the time of acceleration, electric power is supplied from the power storage device 30 and a driving force by the second motor generator 42 is further added.

減速時、制動時には、駆動輪２３が第２モータジェネレータ４２を駆動し、発電機として作動させて回生発電を実施する。この回生した電力は、蓄電装置３０に蓄電される。停車時には、冷房時、エンジン暖機中、充電時を除き、エンジン２０及びモータジェネレータ４１，４２は停止している。蓄電装置３０への充電が必要な場合の走行時には、通常走行時よりも多めにモータジェネレータ４１，４２を駆動させて余剰電力を蓄電装置３０に充電する。   During deceleration and braking, the drive wheel 23 drives the second motor generator 42 and operates as a generator to perform regenerative power generation. The regenerated power is stored in the power storage device 30. When the vehicle is stopped, the engine 20 and the motor generators 41 and 42 are stopped except during cooling, during engine warm-up, and during charging. When traveling when the power storage device 30 needs to be charged, the motor generators 41 and 42 are driven more than during normal travel to charge the power storage device 30 with surplus power.

次に、非接触給電制御装置が実施する給電に係る動作について、図４を参照して説明する。図４は、第１実施形態に係るシステムにおいて、車両への充電運転の際に実行する処理手順を示したメインフローチャートである。   Next, operations related to power feeding performed by the non-contact power feeding control device will be described with reference to FIG. FIG. 4 is a main flowchart showing a processing procedure executed in the charging operation of the vehicle in the system according to the first embodiment.

図４に示すように、まずステップ１で、充電のための給電要求があるか否かを判定する。給電要求は、例えば、ユーザー等の操作に基づいた蓄電装置３０への充電要求や補機類の駆動要求があると満たされる。   As shown in FIG. 4, first, in step 1, it is determined whether or not there is a power supply request for charging. The power supply request is satisfied when, for example, there is a request for charging the power storage device 30 or a request for driving auxiliary equipment based on an operation by a user or the like.

給電要求が満たされたと判定すると、ステップ２で車両１の周辺に生体が検知されたか否かを判定する。この生体検知は、例えば、上記の第１の生体検知〜第４の生体検知のいずれか、または２つ以上を組み合わせて実施することができる。   If it is determined that the power supply request is satisfied, it is determined in step 2 whether or not a living body is detected around the vehicle 1. This living body detection can be performed by, for example, any one of the first to fourth living body detections or a combination of two or more.

ステップ２で生体が検知されたと判定すると、ステップ５以降の給電運転に移行せずに、次にステップ３で生体の検知後、設定されたα分が経過したか否かを判定する。この設定時間α分は、例えば現在の蓄電装置３０のＳＯＣと充電を終了する条件である終了ＳＯＣとの差に応じて決定される。設定時間α分は、当該ＳＯＣの差が小さいほど長く設定され、大きいほど短く設定される値である。つまり、設定時間α分は、デフォルト値は所定時間、例えば１５分に設定されているが、充電運転毎に更新される値である。   If it is determined in step 2 that a living body has been detected, it is determined whether or not the set α has elapsed after detection of the living body in step 3 without shifting to the power supply operation in step 5 and subsequent steps. This set time α is determined, for example, according to the difference between the current SOC of power storage device 30 and the end SOC, which is a condition for ending charging. The set time α is a value that is set longer as the SOC difference is smaller and shorter as the SOC is larger. That is, the set time α minutes is a value that is updated every charging operation, although the default value is set to a predetermined time, for example, 15 minutes.

まだ、ステップ３でα分が経過していないと判定した場合はステップ１に戻るが、α分が経過したと判定すると、車両制御ＥＣＵ９は、車両１の乗員や車両１の周辺に給電が開始できない状況であることを知らせるように報知部１３を制御する。報知部１３による報知後は、ステップ１に戻る。   If it is determined in step 3 that the α minute has not yet elapsed, the process returns to step 1; however, if it is determined that the α minute has elapsed, the vehicle control ECU 9 starts supplying power to the passengers in the vehicle 1 and the vicinity of the vehicle 1. The notification unit 13 is controlled to notify that the situation is not possible. After the notification by the notification unit 13, the process returns to step 1.

報知部１３は、車両１の乗員や車両１の周辺に対し、音声手段、照明手段、または表示手段によって生体検知情報、給電電力の制限情報を知らせる。音声の場合はホーンやドア開閉時の電子音、照明の場合はヘッドライト、ルームランプ、テールランプ等の点灯やハザード点滅、表示の場合はハンドルの前方またはダッシュボードの中央部に配された計器表示盤の一部に配置される液晶ディスプレイで表示等を実施する。これは、α分経過しても給電が開始できない状態であることを解消し、早期に充電を開始して充電時間を確保するための手段である。このように、車両１が有する音発生手段、照明手段、または表示手段を活用した報知を行うことにより、車両１の乗員や周囲の人に、効果的、早急に電磁界からの影響を受け得る生体を遠ざけるように促すことができる。   The notification unit 13 notifies the occupant of the vehicle 1 and the surroundings of the vehicle 1 of the living body detection information and the power supply power limit information by means of sound means, illumination means, or display means. In the case of sound, a horn or electronic sound at the time of opening / closing the door, in the case of lighting, lighting of headlights, room lamps, tail lamps, etc., and blinking of hazards, in the case of display, the instrument display located in front of the handle or in the center of the dashboard Display on a liquid crystal display placed on a part of the board. This is a means for resolving the situation where the power supply cannot be started even after the elapse of α minutes and starting charging at an early stage to ensure the charging time. As described above, by using the sound generation means, illumination means, or display means of the vehicle 1, the passengers of the vehicle 1 and the surrounding people can be effectively and immediately affected by the electromagnetic field. It can be urged to keep the living body away.

ステップ２で生体が検知されないと判定すると、給電を開始するための障害となる生体や通信機器の誤作動等の問題が生じていないと判断でき、以降の給電運転に向けての準備を整える。ステップ５で車両１側の給電準備を実施し、ステップ６で給電器側の給電準備を実施する。   If it is determined in step 2 that a living body is not detected, it can be determined that there is no problem such as a malfunction of a living body or a communication device that becomes an obstacle for starting power supply, and preparations for subsequent power supply operation are made. In step 5, power supply preparation on the vehicle 1 side is performed, and in step 6, power supply preparation on the power feeder side is performed.

車両１側の給電準備は、車両１側の給電制御用スイッチをＯＮし、システムメインリレーを蓄電装置３０側に接続する。さらに、各種ＥＣＵへの電源供給のため、降圧コンバータ３２を駆動するとともに、充電を終了する条件である終了ＳＯＣを所定のマップを用いて算出して設定する。給電器側の給電準備は、給電器側の給電制御用スイッチをＯＮし、システムメインリレーを給電器の二次側に接続する。   For power supply preparation on the vehicle 1 side, the power supply control switch on the vehicle 1 side is turned on, and the system main relay is connected to the power storage device 30 side. Further, in order to supply power to various ECUs, the step-down converter 32 is driven, and an end SOC, which is a condition for ending charging, is calculated and set using a predetermined map. For power supply preparation on the power supply side, the power supply control switch on the power supply side is turned ON, and the system main relay is connected to the secondary side of the power supply.

車両１側及び給電器側の給電準備が整うと、ステップ７で給電を開始し、ステップ８で給電指令電力を読み込み、これに応じて給電を制御する（ステップ９）。給電制御後は、蓄電装置３０の蓄電量が充電終了ＳＯＣの条件が成立するまで給電を継続する。ステップ１０で充電終了ＳＯＣの条件が成立したと判定すると給電を終了し、本フローチャートは終了する。ステップ１０で充電終了ＳＯＣの条件がまだ成立していないと判定すると、ステップ１１で先のステップ２と同様の生体検知の判定を実施する。ステップ１１で生体が検知されていないと判定すると、ステップ９に戻り、給電制御を継続する。   When power supply preparation on the vehicle 1 side and the power supply side is completed, power supply is started in step 7, power supply command power is read in step 8, and power supply is controlled accordingly (step 9). After the power feeding control, the power feeding is continued until the amount of power stored in the power storage device 30 satisfies the condition of the charging end SOC. When it is determined in step 10 that the condition for the charge termination SOC is satisfied, the power supply is terminated, and this flowchart is terminated. If it is determined in step 10 that the condition for the charge termination SOC has not yet been established, in step 11 biometric detection determination similar to that in step 2 is performed. If it determines with the biological body not being detected at step 11, it will return to step 9 and will continue electric power feeding control.

ステップ１１における生体検知判定は、地上側給電部１１１からの給電中、すなわち、充電運転中に実施される生体検知判定である。この生体検知判定は、充電運転中に生体が検知された場合に、電磁界からの影響を憂慮して給電を制限する処理を実施するためのトリガーとなる。また、この生体検知判定では、後述する第１〜第４の生体検知フローによって生体の有無を判定することができる。   The living body detection determination in step 11 is a living body detection determination performed during power feeding from the ground-side power feeding unit 111, that is, during a charging operation. This living body detection determination serves as a trigger for performing processing for restricting power feeding in consideration of the influence from the electromagnetic field when a living body is detected during the charging operation. In this living body detection determination, the presence or absence of a living body can be determined by first to fourth living body detection flows described later.

ステップ１１で生体が検知されたと判定すると、ステップ１２で給電指令電力制限を実施する。この給電指令電力制限における電力の制限値は例えば通常の１／２の出力である。この処理により、給電を中断しないで充電終了へ近づくように制御しつつ、生体への悪影響を抑制した給電も実施できるのである。   If it is determined in step 11 that a living body has been detected, power supply command power limitation is performed in step 12. The power limit value in the power supply command power limit is, for example, a normal ½ output. With this process, it is possible to carry out power feeding that suppresses adverse effects on the living body while controlling to approach the end of charging without interrupting power feeding.

次にステップ１３で、給電電力の制限実施後、設定されたβ分が経過したか否かを判定する。この設定時間β分は、先のα分と同様に、現在の蓄電装置３０のＳＯＣと充電を終了する条件である終了ＳＯＣとの差に応じて決定される。設定時間β分は、当該ＳＯＣの差が小さいほど長く設定され、大きいほど短く設定される値である。つまり、設定時間β分は、デフォルト値は所定時間、例えば１５分に設定されているが、充電運転毎に更新される値である。   Next, in step 13, it is determined whether or not the set β has elapsed after the power supply power restriction. This set time β is determined according to the difference between the current SOC of power storage device 30 and the end SOC, which is a condition for ending charging, in the same manner as the previous α minutes. The set time β is a value that is set longer as the SOC difference is smaller and shorter as the SOC difference is larger. That is, the set time β is a value that is updated every charge operation, although the default value is set to a predetermined time, for example, 15 minutes.

まだ、ステップ１３でβ分が経過していないと判定した場合はステップ９に戻り、給電制御を継続するが、β分が経過したと判定すると、車両制御ＥＣＵ９は、車両１の乗員や車両１の周辺に給電を制限している状況であることを知らせるように報知部１３を制御する。報知部１３による報知後は、再びステップ９に戻り、給電制御を継続する。   If it is determined in step 13 that β minutes have not yet elapsed, the process returns to step 9 to continue power supply control. However, if it is determined that β minutes have elapsed, the vehicle control ECU 9 determines that the occupant of the vehicle 1 or the vehicle 1 The informing unit 13 is controlled so as to notify that there is a situation where power supply is restricted in the vicinity of the. After the notification by the notification unit 13, the process returns to step 9 again to continue power supply control.

次に、上記のステップ２及びステップ１１で実施する生体検知判定の処理について、図５、図８、図１０及び図１１を参照して説明する。   Next, the biometric detection determination process performed in steps 2 and 11 will be described with reference to FIGS. 5, 8, 10, and 11.

（第１の生体検知に係るフロー）
まず、図５を参照して第１の生体検知フローを説明する。この第１の生体検知フローの実行により、車両１の周辺における生体の有無を判定し、その判定結果に対応する以降の適切な処理を実行することができるのである。図５に示すように、ステップ２０で、駐車完了状態であるか否かを判定する。このステップ２０では、例えば車両１が停車し、車両１の車両側受電部１１が地上側給電部１１１に給電可能な所定範囲内に位置しているか否かを判定する。この判定は駐車完了状態になるまで継続される。 (Flow related to first living body detection)
First, the first living body detection flow will be described with reference to FIG. By executing this first living body detection flow, it is possible to determine the presence or absence of a living body in the vicinity of the vehicle 1, and to perform appropriate processing subsequent to the determination result. As shown in FIG. 5, in step 20, it is determined whether or not the parking is complete. In this step 20, for example, it is determined whether or not the vehicle 1 is stopped and the vehicle-side power reception unit 11 of the vehicle 1 is located within a predetermined range in which power can be supplied to the ground-side power supply unit 111. This determination is continued until the parking is completed.

ステップ２０で駐車完了状態であると判定すると、次にステップ２１で、画像処理ＥＣＵ６は、車両１に搭載されたカメラ６１で撮影した車両周辺の画像を電気信号として取得する。そして、画像処理ＥＣＵ６は、ステップ２２で電気信号として取得した画像データを解析して画像処理を実行し、画像処理の結果を用いて画像データに含まれる撮像範囲で生体が存在するか否かを判定する。   If it is determined in step 20 that the parking is complete, then in step 21, the image processing ECU 6 acquires an image around the vehicle taken by the camera 61 mounted on the vehicle 1 as an electrical signal. Then, the image processing ECU 6 analyzes the image data acquired as the electrical signal in step 22 and executes the image processing, and uses the result of the image processing to determine whether or not a living body exists in the imaging range included in the image data. judge.

ステップ２２の判定が「生体の存在なし」の場合は、ステップ２４で「生体なし」のフラグを立て、ステップ５やステップ８に進み、本フローを終了する。ステップ２２の判定が「生体の存在有り」の場合は、ステップ２３で「生体有り」のフラグを立て、ステップ３やステップ１２に進み、本フローを終了する。   If the determination in step 22 is “no living body is present”, the flag “no living body” is set in step 24, the process proceeds to step 5 or step 8, and this flow is terminated. If the determination in step 22 is “the presence of a living body”, a flag “having a living body” is set in step 23, the process proceeds to step 3 or step 12, and this flow is terminated.

以上の図４を参照して説明した充電運転における、生体検知、給電電力、蓄電装置３０のＳＯＣの関係について、図６にしたがって説明する。図６は、充電運転における生体判定の結果に応じた車両１への給電電力の変化とＳＯＣの変化を示したタイムチャートである。   The relationship between the living body detection, the feed power, and the SOC of the power storage device 30 in the charging operation described with reference to FIG. 4 will be described with reference to FIG. FIG. 6 is a time chart showing changes in the power supplied to the vehicle 1 and changes in the SOC according to the result of the living body determination in the charging operation.

図６に示すように、給電開始時に、生体判定が生体を検知している間は、給電は０[ｋＷ]であり、給電を行っていない。そして、生体が検知されなくなると、給電の電力が２[ｋＷ]に増加するため、その間の現ＳＯＣは終了ＳＯＣに向けて順調に増加し続ける。しかし、給電中に、再び生体が検知されると、給電の電力が再び１[ｋＷ]に制限されているため、その間のＳＯＣは微増状態に戻る。また生体が検知されなくなると、給電の電力が２[ｋＷ]に増加するため、その間の現ＳＯＣは終了ＳＯＣに向けて順調に増加し続け、終了ＳＯＣに達すると、給電が停止し、充電運転を終了する。もちろん、給電の電力制限は１[ｋＷ]よりも低い０．５[ｋＷ]や、０．５[ｋＷ]未満で０[ｋＷ]以上の範囲に含まれる所定の値で実施してもよい。   As shown in FIG. 6, while the biometric determination is detecting a living body at the start of power feeding, the power feeding is 0 [kW], and power feeding is not performed. When the living body is no longer detected, the power supplied is increased to 2 [kW], and the current SOC during that time continues to increase smoothly toward the end SOC. However, if a living body is detected again during power feeding, the power supplied is limited to 1 [kW] again, so the SOC during that time returns to a slightly increased state. When the living body is no longer detected, the power supplied to the power supply increases to 2 [kW]. Therefore, the current SOC during that time continues to increase smoothly toward the end SOC, and when the end SOC is reached, the power supply stops and the charging operation is performed. Exit. Of course, the power limitation of the power supply may be performed with a predetermined value included in a range of 0.5 [kW] lower than 1 [kW], or less than 0.5 [kW] and 0 [kW] or more.

（第２の生体検知に係るフロー）
次に、図８を参照して第２の生体検知フローを説明する。この第２の生体検知フローの実行により、車両１の周辺における生体の有無を判定し、その判定結果に対応する以降の適切な処理を実行することができるのである。図８に示すように、ステップ２０で、駐車完了状態であるか否かを判定する。このステップ２０では、例えば車両１が停車した状態で、車両１の車両側受電部１１が地上側給電部１１１に給電可能な所定範囲内に位置しているか否かを判定する。この判定は駐車完了状態になるまで継続される。 (Flow related to second living body detection)
Next, the second living body detection flow will be described with reference to FIG. By executing this second living body detection flow, it is possible to determine the presence or absence of a living body in the vicinity of the vehicle 1, and to execute appropriate processing subsequent to the determination result. As shown in FIG. 8, it is determined in step 20 whether or not the vehicle is in a parking completion state. In this step 20, for example, it is determined whether or not the vehicle-side power reception unit 11 of the vehicle 1 is located within a predetermined range in which power can be supplied to the ground-side power supply unit 111 while the vehicle 1 is stopped. This determination is continued until the parking is completed.

ステップ２０で駐車完了状態であると判定すると、次にステップ２１ａで、まず、コーナーセンサＥＣＵ７は、車両１に搭載されたコーナーセンサであるセンサ７１〜７４によって車両周辺における初期状態の障害物を検出する。これは、初期状態として、車両周辺に壁、フェンス、隣の車両等が存在するかどうかを検出する処理である。   If it is determined in step 20 that the parking is complete, then in step 21a, the corner sensor ECU 7 first detects obstacles in the initial state around the vehicle by means of sensors 71 to 74 which are corner sensors mounted on the vehicle 1. To do. This is a process of detecting whether there are walls, fences, adjacent vehicles, etc. around the vehicle as an initial state.

そして、コーナーセンサＥＣＵ７は、ステップ２２ａで、センサ７１〜７４による車両周辺の障害物を検出する。このときの検出結果が、先のステップ２１ａでの初期状態の検出結果と比較して異なる障害物の検出を確認できるものかどうかを判定する。ステップ２２ａの判定が新たな障害物を検出しないものであるときには、ステップ２４で「生体なし」のフラグを立て、ステップ５やステップ８に進み、本フローを終了する。ステップ２２ａの判定が新たな障害物を検出するものであるときには、ステップ２３で「生体有り」のフラグを立て、ステップ３やステップ１２に進み、本フローを終了する。   Then, the corner sensor ECU 7 detects obstacles around the vehicle by the sensors 71 to 74 in step 22a. It is determined whether the detection result at this time can confirm the detection of a different obstacle compared with the detection result of the initial state in the previous step 21a. If the determination in step 22a does not detect a new obstacle, a flag “no living body” is set in step 24, the process proceeds to step 5 or step 8, and this flow ends. If the determination in step 22a is to detect a new obstacle, a flag “living body” is set in step 23, the process proceeds to step 3 or step 12, and this flow is terminated.

（第３の生体検知に係るフロー）
次に、図１０を参照して第３の生体検知フローを説明する。この第３の生体検知フローの実行により、車両１の周辺における生体の有無を判定し、その判定結果に対応する以降の適切な処理を実行することができるのである。図１０に示すように、ステップ２０ａ、ステップ２２ｂでは、スマートＥＣＵ８は、車両１の外に固有管理番号に該当するスマートキーがあるか否かを判定する。ステップ２０ａでは、スマートキーを所持した者が所定のキー検知範囲Ｄ３に入ったか否かを判定することができる。この判定はスマートキーの固有管理番号を受信するまで繰り返される。 (Flow related to third living body detection)
Next, a third living body detection flow will be described with reference to FIG. By executing the third living body detection flow, it is possible to determine the presence or absence of a living body in the vicinity of the vehicle 1 and to execute appropriate processes subsequent to the determination result. As shown in FIG. 10, in step 20a and step 22b, the smart ECU 8 determines whether or not there is a smart key corresponding to the unique management number outside the vehicle 1. In step 20a, it can be determined whether or not the person who has the smart key has entered the predetermined key detection range D3. This determination is repeated until the smart key unique management number is received.

ステップ２０ａでキー検知範囲Ｄ３にキーが存在すると判定すると、次にステップ２２ｂで、検知されたキーの固有管理番号が車両１に登録されている固有管理番号と一致するか否かを判定する。スマートＥＣＵ８が、ステップ２２ｂで検知されたキーの固有管理番号と車両１の固有管理番号とが一致しないと判定した場合は、ステップ２４で「生体なし」のフラグを立て、ステップ５やステップ８に進み、本フローを終了する。スマートＥＣＵ８が、ステップ２２ｂで車両１の固有管理番号と一致する電気信号を受信したときは、キー照合がなされたとして車両１固有のスマートキーを所持する者が車両１の周辺に存在するとして、ステップ２３で「生体有り」のフラグを立て、ステップ３やステップ１２に進み、本フローを終了する。   If it is determined in step 20a that a key exists in the key detection range D3, then in step 22b, it is determined whether or not the unique management number of the detected key matches the unique management number registered in the vehicle 1. If the smart ECU 8 determines that the unique management number of the key detected in step 22b and the unique management number of the vehicle 1 do not match, a flag “no living body” is set in step 24, and in steps 5 and 8 Proceed and end this flow. When the smart ECU 8 receives an electric signal that matches the unique management number of the vehicle 1 in step 22b, it is assumed that a person who possesses the smart key unique to the vehicle 1 exists in the vicinity of the vehicle 1 as a result of the key verification. In step 23, a “living body present” flag is set, the process proceeds to step 3 or step 12, and this flow is terminated.

（第４の生体検知に係るフロー）
次に、図１１を参照して第４の生体検知フローを説明する。この第４の生体検知フローの実行により、車両１の周辺における生体の有無を判定し、その判定結果に対応する以降の適切な処理を実行することができるのである。図１１に示すように、ステップ２０で、駐車完了状態であるか否かを判定する。このステップ２０では、例えば車両１が停車した状態で、車両１の車両側受電部１１が地上側給電部１１１に給電可能な所定範囲内に位置しているか否かを判定する。この判定は駐車完了状態になるまで継続される。 (Flow related to fourth living body detection)
Next, a fourth living body detection flow will be described with reference to FIG. By executing this fourth living body detection flow, it is possible to determine the presence or absence of a living body in the vicinity of the vehicle 1 and to execute appropriate processing subsequent to the determination result. As shown in FIG. 11, in step 20, it is determined whether or not the parking is complete. In this step 20, for example, it is determined whether or not the vehicle-side power reception unit 11 of the vehicle 1 is located within a predetermined range in which power can be supplied to the ground-side power supply unit 111 while the vehicle 1 is stopped. This determination is continued until the parking is completed.

ステップ２０で駐車完了状態であると判定すると、車両制御ＥＣＵ９は、ステップ２１ｃ１で車両１の位置情報を取得する。さらに車両制御ＥＣＵ９は、ステップ２１ｃ２で、上述したように車両周辺に携帯機器１２０が存在する場合にはその正確な位置情報を取得する。そして、車両制御ＥＣＵ９は、ステップ２２ｃで、取得できた車外の携帯機器１２０の位置が車両１に対して予め設定された範囲内にあるか否かを判定する。   If it determines with it being a parking completion state by step 20, vehicle control ECU9 will acquire the positional information on the vehicle 1 by step 21c1. Furthermore, vehicle control ECU9 acquires the exact positional information, when the portable apparatus 120 exists in the vehicle periphery as mentioned above at step 21c2. In step 22c, the vehicle control ECU 9 determines whether the acquired position of the portable device 120 outside the vehicle is within a preset range with respect to the vehicle 1.

車両制御ＥＣＵ９が、ステップ２２ｃで当該携帯機器１２０の位置が車両１に対する設定範囲内にはないと判定した場合は、携帯機器１２０を所持する生体が電磁界によって悪影響を受けることはないと判断して、ステップ２４で「生体なし」のフラグを立て、ステップ５やステップ８に進み、本フローを終了する。車両制御ＥＣＵ９が、ステップ２２ｃで当該携帯機器１２０の位置が当該設定範囲内にあると判定した場合は、携帯機器１２０を所持する生体が電磁界によって悪影響を受けることおそれがあるため、ステップ２３で「生体有り」のフラグを立て、ステップ３やステップ１２に進み、本フローを終了する。   If the vehicle control ECU 9 determines in step 22c that the position of the portable device 120 is not within the set range with respect to the vehicle 1, it is determined that the living body holding the portable device 120 is not adversely affected by the electromagnetic field. In step 24, the “no living body” flag is set, the process proceeds to step 5 or step 8, and this flow is terminated. If the vehicle control ECU 9 determines in step 22c that the position of the mobile device 120 is within the set range, the living body holding the mobile device 120 may be adversely affected by the electromagnetic field. The “living body present” flag is set, the process proceeds to step 3 or step 12, and this flow is terminated.

本実施形態の非接触給電制御装置がもたらす作用効果について説明する。非接触給電制御装置は、車両１の外部に設けられる地上側給電部１１１から車両１に設けられる車両側受電部１１へ非接触で電力を送る給電を制御する。非接触給電制御装置は、車両側受電部１１への給電運転中に、地上側給電部１１１の周辺において生体の存在を検知したとき（ステップ１１）は、車両側受電部１１へ給電する給電電力を、生体の存在が検知されていない場合と比べて制限する（ステップ１２）。   The effect which the non-contact electric power feeding control apparatus of this embodiment brings is demonstrated. The non-contact power supply control device controls power supply that transmits power in a non-contact manner from a ground-side power supply unit 111 provided outside the vehicle 1 to a vehicle-side power reception unit 11 provided in the vehicle 1. When the non-contact power supply control device detects the presence of a living body in the vicinity of the ground-side power supply unit 111 during the power supply operation to the vehicle-side power reception unit 11 (step 11), the non-contact power supply control device supplies power to the vehicle-side power reception unit 11 Is compared with the case where the presence of a living body is not detected (step 12).

これによれば、給電運転中に生体を検知した場合は、電磁界による生体への悪影響が生じない程度に給電の電力を制限する給電運転を行って給電を継続することにより、給電を停止することなく、生体への悪影響を抑制しつつ車両１に走行用電力を充電することができる。したがって、車両１への非接触給電を行う際に、生体への悪影響を抑制しつつ車両１への走行用電力を充電することができるため、人体、動物等に対する電磁界の影響の低減及び車両１の充電時間の長期化防止を実現できる。   According to this, when the living body is detected during the power feeding operation, the power feeding is stopped by performing the power feeding operation that limits the power of the power feeding to such an extent that the electromagnetic field does not adversely affect the living body, thereby stopping the power feeding. Therefore, it is possible to charge the vehicle 1 with traveling power while suppressing adverse effects on the living body. Accordingly, when non-contact power feeding to the vehicle 1 is performed, it is possible to charge the traveling power to the vehicle 1 while suppressing adverse effects on the living body, thereby reducing the influence of the electromagnetic field on the human body, animals, etc. 1 can prevent the charging time from being prolonged.

車両が地上側給電部から車両側受電部への給電が可能な位置に停車し、かつ車両側から給電要求があった場合に、例えば、車両のドアの施錠を検出してから給電を開始すると、まだ車両の傍に人がいる可能性があり、電磁界の影響を受けてしまうおそれがある。本実施形態の非接触給電制御装置では、上記の第１の生体検知手段から第４の生体検知手段の少なくとも一つによって生体を検出するため、車両周辺に留まって車両からまだ十分に離れていない人を検出することが可能である。したがって、このような場合に電磁界からの影響の懸念を解消できるのである。   When the vehicle stops at a position where power can be supplied from the ground-side power supply unit to the vehicle-side power reception unit, and when there is a power supply request from the vehicle side, for example, when power supply is started after detecting locking of the door of the vehicle There may still be people near the vehicle and there is a risk of being affected by the electromagnetic field. In the non-contact power supply control device according to the present embodiment, the living body is detected by at least one of the first living body detecting means to the fourth living body detecting means, so that it stays in the vicinity of the vehicle and is not yet sufficiently separated from the vehicle. It is possible to detect people. Therefore, in such a case, the concern about the influence from the electromagnetic field can be solved.

また、給電運転中に、車両のドアの開錠を検出してから給電運転を停止等する場合には、開錠の検出前に、人が車両の傍にいる可能性があり、この場合も電磁界からの影響を受けてしまうおそれがある。本実施形態の非接触給電制御装置では、上記の第１の生体検知手段から第４の生体検知手段の少なくとも一つによって生体を検出するため、ドアの開錠前に車両に近づいている人を検出可能である。したがって、このような場合に電磁界からの影響の懸念を解消できるのである。   Also, when stopping the power feeding operation after detecting the unlocking of the vehicle door during the power feeding operation, there is a possibility that a person is near the vehicle before the unlocking is detected. There is a risk of being affected by electromagnetic fields. In the non-contact power supply control device according to the present embodiment, since the living body is detected by at least one of the first living body detecting means to the fourth living body detecting means, a person approaching the vehicle is detected before the door is unlocked. Is possible. Therefore, in such a case, the concern about the influence from the electromagnetic field can be solved.

非接触給電制御装置は、給電電力を制限した給電運転中に、再び、地上側給電部１１１の周辺において生体の存在を検知したときは、当該給電電力の制限を継続する（ステップ１１、ステップ１２）。これによれば、一旦、給電電力の制限を実施して生体への電磁界の影響を抑制する状態を、生体が検知され続けている間は維持する。この制御により、給電運転中に生体が電磁界の影響を受ける可能性がある場合には電力制限を伴う給電を継続できるため、安全性に優れた給電運転を継続的に実施できる。   When the presence of a living body is detected again around the ground-side power feeding unit 111 during the power feeding operation in which the power feeding power is limited, the non-contact power feeding control device continues to limit the power feeding power (steps 11 and 12). ). According to this, the state where the power supply power is once limited to suppress the influence of the electromagnetic field on the living body is maintained while the living body is continuously detected. With this control, when there is a possibility that the living body may be affected by the electromagnetic field during the power feeding operation, the power feeding with the power limitation can be continued. Therefore, the power feeding operation with excellent safety can be continuously performed.

非接触給電制御装置は、給電運転を実施する給電運転要求があり、かつ給電運転を実施する前に、地上側給電部１１１の周辺において生体の存在を検知したときは、給電運転を開始しない（ステップ２、ステップ３）。これによれば、給電を行っていないときに、例えば給電停止中に生体を検知すると、給電運転要求があった場合でも給電運転を開始しない。これにより、給電運転要求に反しても給電停止状態を維持するため、給電開始と同時に生体が電磁界から影響を受ける可能性を未然に防止するのである。   The non-contact power supply control device does not start the power supply operation when there is a power supply operation request for performing the power supply operation and the presence of a living body is detected around the ground-side power supply unit 111 before the power supply operation is performed ( Step 2, Step 3). According to this, when power supply is not performed, for example, when a living body is detected while power supply is stopped, the power supply operation is not started even when there is a power supply operation request. Thus, since the power supply stop state is maintained even when the power supply operation request is violated, the possibility that the living body is affected by the electromagnetic field at the same time as the start of power supply is prevented.

非接触給電制御装置は、給電電力を制限している時間が設定された時間よりも長くなると、外部に向けて報知する（ステップ４、ステップ１４）。これによれば、電力制限の時間が長引いた場合には人に対して報知することにより、生体の接近した状態を早急に解消することができる。このように早急に解消した後は、通常の電力で給電運転を実施することも可能になるので、車両１の蓄電装置３０等への充電に要する時間を短くすることができる。したがって、早期の充電完了を実現できる。   The non-contact power supply control device notifies the outside when the time during which the power supply is limited is longer than the set time (steps 4 and 14). According to this, when the time of power limitation is prolonged, a state in which the living body is approaching can be quickly resolved by notifying a person. Since the power supply operation can be performed with normal electric power after it is resolved quickly as described above, the time required for charging the power storage device 30 and the like of the vehicle 1 can be shortened. Therefore, early completion of charging can be realized.

非接触給電制御装置は、外部に向けて報知するときのトリガーとなる上記の設定された時間（例えば、α分、β分）を、現在の蓄電装置３０のＳＯＣと終了ＳＯＣとの差に基づいて決定する（ステップ３、ステップ１３）。これによれば、現在のＳＯＣと終了ＳＯＣとの差の大きさに応じて、外部への報知を開始するまでの時間を短く設定することが可能になり、給電制限を行わない給電運転時間を多く確保することもできる。例えば、現在のＳＯＣと終了ＳＯＣとの差が大きい場合は、α分やβ分を短く設定することにより、給電制限を行う給電運転を早期に終了させるために早期に報知を実施し、給電制限のない給電運転時間を多く確保するので、生体への電磁界の影響を抑制し、かつ車両への充電終了を早期に実現する制御を提供することができる。   The non-contact power supply control device determines the set time (for example, α minutes and β minutes) that becomes a trigger when reporting to the outside based on the difference between the SOC of the current power storage device 30 and the end SOC. (Step 3 and Step 13). According to this, it becomes possible to set the time until the start of notification to the outside in accordance with the magnitude of the difference between the current SOC and the end SOC, and the power supply operation time without power supply restriction is set. Many can be secured. For example, when the difference between the current SOC and the end SOC is large, the α and β minutes are set to be short so that the power supply operation for performing the power supply restriction is terminated early and the power supply restriction is performed. Therefore, it is possible to provide a control that suppresses the influence of the electromagnetic field on the living body and realizes the end of charging the vehicle at an early stage.

また、本実施形態の非接触給電システムは、上記の非接触給電制御装置と、地上側給電部１１１の周辺において生体の存在を検知する上記の生体検知手段と、を備える。この構成によれば、給電運転中に、磁界が発生している地上側給電部１１１の周辺に人体等の生体を検知した場合は、検知していない場合と比較して給電電力を制限する給電運転を実施する非接触給電システムを提供できる。   Further, the non-contact power supply system of the present embodiment includes the above-described non-contact power supply control device and the above-described living body detection unit that detects the presence of a living body in the vicinity of the ground-side power supply unit 111. According to this configuration, when a living body such as a human body is detected in the vicinity of the ground-side power supply unit 111 in which a magnetic field is generated during power supply operation, the power supply restricts the power supply compared to the case where it is not detected. A non-contact power supply system that performs operation can be provided.
