Description
本発明は、電力を用いて走行する車両及びその車両の充電を行う充電システムに関する。 The present invention relates to a vehicle that travels using electric power and a charging system that charges the vehicle.
環境問題に関心が高まるにつれ、ハイブリッドカーや電気自動車などの電動機を用いて走行する車両が注目されている。
このような電動機を用いる車両では、車両が搭載している充電池にいかにして電気を充電するかということが問題の一つになっている。
As interest in environmental problems increases, vehicles that run using electric motors such as hybrid cars and electric cars are attracting attention.
In a vehicle using such an electric motor, one of the problems is how to charge electricity to a rechargeable battery mounted on the vehicle.
例えば車両に対して充電を行う際には、充電器のプラグを車両に接続しなければならない煩わしさがあった。
これに対処するものとして特許文献１には、充電器と車両内の充電池をトランス結合しして、充電池に充電を行う構成が開示されている。
For example, when charging a vehicle, there is a troublesome need to connect the plug of the charger to the vehicle.
In order to cope with this, Patent Document 1 discloses a configuration in which a charger and a rechargeable battery in a vehicle are coupled by a transformer to charge the rechargeable battery.
またこれらの車両への充電を行う間、車両を停車させておかねばならず、充電が完了するまで車両を動かすことが出来なかった。そのため例えば、登坂車線を長距離走行するような場合には電池切れの不安がある。充電池への電力供給のための補助として回生充電があるが、回生充電は下り坂以外は充電するのが難しいので、電池切れの不安は解消できない。よって、特定エリア以外で、走行中でも充電可能な充電ゾーンが望まれる。 In addition, the vehicle must be stopped while charging these vehicles, and the vehicle cannot be moved until the charging is completed. Therefore, for example, when traveling on a climbing lane for a long distance, there is a fear of running out of the battery. There is regenerative charging as an auxiliary for power supply to the rechargeable battery, but regenerative charging is difficult to charge except downhill, so the fear of running out of battery cannot be solved. Therefore, a charging zone that can be charged while traveling is desired outside the specific area.
この点に対処するものとして特許文献２には、車道に直流送電線を埋設し、また車両に誘導コイルを設けて、この車両が直流送電線上を走行することにより、誘導コイルに発生する誘導起電力によって充電池を充電する構成が開示されている。 In order to cope with this point, in Patent Document 2, a DC transmission line is embedded in a roadway, an induction coil is provided in a vehicle, and when this vehicle travels on the DC transmission line, induction induction generated in the induction coil is disclosed. A configuration for charging a rechargeable battery with electric power is disclosed.
また特許文献３には、道路にコイルを埋設し、また車両にキャパシタに接続したコイルを搭載して、車両が道路を通過することによってコイルに発生した誘導起電力によって車両を動かす構成が開示されている。 Patent Document 3 discloses a configuration in which a coil is embedded in a road and a coil connected to a capacitor is mounted on the vehicle, and the vehicle is moved by induced electromotive force generated in the coil when the vehicle passes through the road. ing.
本発明は、上述した特許文献１乃至３の構成より、高効率に車両に電力を供給可能な車両充電システム及び車両を提供することを課題とする。 An object of the present invention is to provide a vehicle charging system and a vehicle that can supply power to the vehicle with high efficiency from the configurations of Patent Documents 1 to 3 described above.
本車両充電システムは、道路を車両が通過することにより、当該車両に搭載されている充電池を充電する車両充電システムであって、前記道路は、前記車両が通過する路面内に、前記車両が通過する方向にＳ極とＮ極を交互に配列した永久磁石と、前記電磁誘導コイルと前記永久磁石との位置が前記電磁誘導コイルが電磁誘導を起こせる位置にあることを前記車両に通知するマーカーと、を備え、前記車両は、前記充電池に接続され、前記永久磁石によって電磁誘導電流を発生する電磁誘導コイルと、前記マーカーを検出する検出部と、を備えることを特徴とする。 The vehicle charging system is a vehicle charging system that charges a rechargeable battery mounted on a vehicle when the vehicle passes through the road, and the road is located on a road surface through which the vehicle passes. A permanent magnet in which S poles and N poles are alternately arranged in the passing direction, and a marker for notifying the vehicle that the position of the electromagnetic induction coil and the permanent magnet is a position where the electromagnetic induction coil can cause electromagnetic induction The vehicle includes an electromagnetic induction coil that is connected to the rechargeable battery and generates an electromagnetic induction current by the permanent magnet, and a detection unit that detects the marker.
本車両は、路面を走行する車両であって、充電池と、前記充電池の電力を用いて駆動し、前記車両を走行させるモータと、電磁誘導電流を発生することによって前記充電池を充電する電磁誘導コイルと、前記路面上のマーカーを検出する検出部と、前記検出部による前記マーカーの検出結果に基づいて、前記車両の運転者に通知を行う通知部と、を備えることを特徴とする。 The vehicle is a vehicle that travels on a road surface, and is charged using a rechargeable battery, a motor that drives the vehicle using the power of the rechargeable battery, and generates an electromagnetic induction current. An electromagnetic induction coil, a detection unit that detects a marker on the road surface, and a notification unit that notifies a driver of the vehicle based on a detection result of the marker by the detection unit. .
本発明によれば、安全に安易にかつ高効率に車両に電力を供給することが出来る。 According to the present invention, power can be supplied to a vehicle safely and easily and with high efficiency.
以下に図面を参照しながら本発明の一実施形態について説明する。
図１は、本実施形態における車両充電システムの原理を説明する概念図である。
同図において、本実施形態の車両充電システム１０では、道路１に車両２の進行方向にＳＮＳＮ・・・と配列した永久磁石３を埋め込む。また道路１の表面にはこの永久磁石に平行にマーカーが設置されている。なおこのマーカーについては後述する。
An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a conceptual diagram illustrating the principle of a vehicle charging system in the present embodiment.
In the figure, in the vehicle charging system 10 of the present embodiment, permanent magnets 3 arranged as SNSN... Are embedded in the road 1 in the traveling direction of the vehicle 2. A marker is installed on the surface of the road 1 in parallel with the permanent magnet. This marker will be described later.
車両２には発電コイル４が内蔵されており、車両２が道路１を走行することによって、発電コイル４が永久磁石３の上を通過することとなり、発電コイル４には電流が励起する。 The vehicle 2 has a built-in power generation coil 4. When the vehicle 2 travels on the road 1, the power generation coil 4 passes over the permanent magnet 3, and current is excited in the power generation coil 4.
図２は、車両２内に設けられる発電コイル４を含む電気的構成を示す図である。
道路には永久磁石３が埋設されているので、車両２が道路１を走行すると発電コイル４は、永久磁石３による、車両１の速度に比例した周波数で変化する磁界内に置かれることとなり、発電コイル４に上記周波数の交流電流が励起する。その電流は整流器２１によって直流に変換された後、平滑用コンデンサ２２によって平滑化され、逆流防止用ダイオード及びレギュレータ２３によって定電圧化された後、バッテリー２４及びモータのスイッチを介して車両１の駆動用モータ等に出力される。
FIG. 2 is a diagram showing an electrical configuration including the power generation coil 4 provided in the vehicle 2.
Since the permanent magnet 3 is embedded in the road, when the vehicle 2 travels on the road 1, the power generating coil 4 is placed in a magnetic field that changes at a frequency proportional to the speed of the vehicle 1 by the permanent magnet 3. An alternating current having the above frequency is excited in the power generating coil 4. The current is converted into a direct current by a rectifier 21, smoothed by a smoothing capacitor 22, made constant voltage by a backflow prevention diode and a regulator 23, and then driven by the vehicle 1 via a battery 24 and a motor switch. Output to the motor.
この発電コイル４による発電量は、発電コイル４が道路に埋設されている永久磁石３の真上を通過する場合に、最も大きくなる。したがって常に発電コイル４が永久磁石３の真上に来るように車両１が道路２を走行したほうが、効率よく発電することが出来る。 The amount of power generated by the power generation coil 4 is the largest when the power generation coil 4 passes directly above the permanent magnet 3 embedded in the road. Therefore, it is possible to generate power more efficiently when the vehicle 1 travels on the road 2 so that the power generation coil 4 is always directly above the permanent magnet 3.
本実施形態の車両充電システムでは、車両１が走行中に発電コイル４が永久磁石３の上に来るように、道路２の路面上にマーカーを設け、また車両１にはこのマーカーを検出する検出部を設ける。そして車両１は、道路２を走行する際、このマーカーをセンシングして走行する。 In the vehicle charging system of the present embodiment, a marker is provided on the road surface of the road 2 so that the power generation coil 4 is on the permanent magnet 3 while the vehicle 1 is traveling, and the vehicle 1 is detected to detect this marker. Provide a part. When the vehicle 1 travels on the road 2, the vehicle 1 travels by sensing this marker.
図３に本実施形態の車両充電システム１０によるマーカーの施設の仕方を示す。
図３（ａ）は本実施形態の車両充電システム１０に用いる道路２を上から見た図で、車両が走行する道路の中央に永久磁石３が敷設されておりその両脇にマーカー３１ａが路面上に設置されている。そしてさらに外側には、ガードレール３２が設けられている。なおこのガードレールは、本実施形態の車両充電システム１０とは直接関係がないので、道路２には無くても良い。
FIG. 3 shows a marker facility by the vehicle charging system 10 of the present embodiment.
FIG. 3A is a top view of the road 2 used in the vehicle charging system 10 of the present embodiment. A permanent magnet 3 is laid in the center of the road on which the vehicle travels, and markers 31a are provided on both sides of the road surface. It is installed on the top. Further, a guard rail 32 is provided on the outer side. Note that the guard rail is not directly related to the vehicle charging system 10 of the present embodiment, and thus may not be provided on the road 2.
また図３（ｂ）は、マーカー３１ｂを永久磁石３の上に１つだけ設けた場合を示している。図３（ａ）の場合は車両１にマーカー検出する検出部を２組設ける必要があるが、この図３（ｂ）の場合車両１には検出部は１組設ければよい。 FIG. 3B shows a case where only one marker 31 b is provided on the permanent magnet 3. In the case of FIG. 3 (a), it is necessary to provide two sets of detection units for detecting markers in the vehicle 1, but in the case of FIG. 3 (b), the vehicle 1 may be provided with one set of detection units.
このように本実施形態の車両充電システム１０では、マーカー３１は道路２上に１乃至複数設けることが出来る。
図４は、本実施形態の車両充電システム１０でのマーカー３１の検出部４１によるセンシングを説明する概念図を示す。
Thus, in the vehicle charging system 10 of the present embodiment, one or more markers 31 can be provided on the road 2.
FIG. 4 is a conceptual diagram illustrating sensing by the detection unit 41 of the marker 31 in the vehicle charging system 10 of the present embodiment.
図４（ａ）は車両１と永久磁石３の位置関係が、発電コイル４による発電効率が最も良い状態となっている場合、同図（ｂ）は車両１と永久磁石３の位置関係がずれており、発電コイル４による発電効率が良くない場合での検出部４１によるマーカー３１の検出を示している。 4A shows the positional relationship between the vehicle 1 and the permanent magnet 3 when the power generation efficiency by the power generation coil 4 is in the best state. FIG. 4B shows the positional relationship between the vehicle 1 and the permanent magnet 3 is shifted. The detection of the marker 31 by the detection unit 41 when the power generation efficiency by the power generation coil 4 is not good is shown.
図４では、マーカー３１は路面に塗布された塗料で構成されており、また２つの検出部４１−１及び４１−２はそれぞれ、マーカー３１を照射するセンシング用光源４２とマーカー３１からの反射光を検出するフォトセンサ４３ａ及び４３ｂから構成されている。 In FIG. 4, the marker 31 is made of a paint applied to the road surface, and the two detection units 41-1 and 41-2 are reflected from the sensing light source 42 that irradiates the marker 31 and the marker 31, respectively. It is comprised from the photosensors 43a and 43b which detect this.
図４は、図３（ａ）のように２本のマーカー３１ａが路面上に設けられている場合を例として示しており、車両１は車輪４０で支えられる車体４１の底部に発電コイル４を中心にして、車両１の進行方向に対して垂直に、マーカー３１ａと同じ間隔で並べる形で、検出部４２−１及び４２−２を備えている。また各検出部４２−１及び４２−２は、２つのフォトセンサ４４ａ及び４４ｂを、センシング用光源４３を中心にして車両１の進行方向に対して垂直に並べる形で備えている。 FIG. 4 shows an example in which two markers 31a are provided on the road surface as shown in FIG. 3 (a). The vehicle 1 has a power generation coil 4 at the bottom of a vehicle body 41 supported by wheels 40. The detectors 42-1 and 42-2 are provided in the form of being arranged at the same interval as the marker 31a at the center and perpendicular to the traveling direction of the vehicle 1. Each of the detection units 42-1 and 42-2 includes two photosensors 44a and 44b that are arranged vertically with respect to the traveling direction of the vehicle 1 with the sensing light source 43 as the center.
そして図４（ａ）のように発電コイル４が永久磁石３の真上にあるときは、検出部４２−１及び４２−２はマーカー３１ａが真下にあることを検出し、車両１が道路２の適宜な位置を走行していることを運転者に通知する。 When the power generating coil 4 is directly above the permanent magnet 3 as shown in FIG. 4A, the detection units 42-1 and 42-2 detect that the marker 31a is directly below, and the vehicle 1 is on the road 2 The driver is notified that the vehicle is traveling at an appropriate position.
また車両１が左右どちらかにずれている場合には、検出部４２−１及び４２−２のフォトセンサ４４ａ及び４４ｂの何れか一方しかマーカー３１ａからの反射光を検出しない。したがって検出部４２−１及び４２−２は、車両１が右若しくは左にずれていることがずれている方向と共に検出できる。またフォトセンサ４４ａ及び４４ｂの出力値の大きさは反射光の大きさに比例するので、出力値の大きさから、車両１のずれている量も検出することが出来る。 When the vehicle 1 is shifted to the left or right, only one of the photosensors 44a and 44b of the detection units 42-1 and 42-2 detects the reflected light from the marker 31a. Therefore, the detection units 42-1 and 42-2 can detect that the vehicle 1 is shifted to the right or left along with the direction in which the vehicle 1 is shifted. Since the magnitudes of the output values of the photosensors 44a and 44b are proportional to the magnitude of the reflected light, the amount of deviation of the vehicle 1 can also be detected from the magnitude of the output value.
図４（ｂ）では、車両１は道路２の永久磁石３が埋設されている位置から左にずれているので、フォトセンサ４４ｂのみがマーカー３１ａからの反射光を検出している。したがって車両１から運転者に対して車両１が左にずれていることが通知部によって通知され、これを受けて運転者は車両１のハンドルを右にきることによりにより、車両１の発電コイル４と永久磁石３が発電量の多い適宜な位置関係となる。 In FIG. 4B, since the vehicle 1 is shifted to the left from the position where the permanent magnet 3 on the road 2 is embedded, only the photosensor 44b detects the reflected light from the marker 31a. Therefore, the notification unit notifies the driver of the vehicle 1 from the vehicle 1 to the left, and the driver turns the steering wheel of the vehicle 1 to the right in response to the notification. The permanent magnet 3 has an appropriate positional relationship with a large amount of power generation.
図５は、車両１に搭載される通知部による表示例を示す図である。
本実施形態の車両充電システム１０では、車両１の発電コイル４が道路２に埋設されている永久磁石３からずれると、検出部４２による検出結果に基づいて、フロントパネル等に設けられた図５のような通知部によって、運転者にずれた方向とその量を通知する。
FIG. 5 is a diagram illustrating a display example by a notification unit mounted on the vehicle 1.
In the vehicle charging system 10 of the present embodiment, when the power generation coil 4 of the vehicle 1 deviates from the permanent magnet 3 embedded in the road 2, FIG. 5 provided on the front panel or the like based on the detection result by the detection unit 42. The notification unit like this notifies the driver of the direction and amount of displacement.
通知部５０はＬＥＤや液晶パネル等で構成され、同図では左右を示す表示セグメント５２ａ、５２ｂを表示することによって、運転者に車両１が定位置からずれていることを通知する。これを見た運転者は、車両１が道路２上の適宜な位置を走行するようにハンドル操作を行う。 The notification unit 50 includes an LED, a liquid crystal panel, and the like, and displays display segments 52a and 52b indicating left and right in the figure, thereby notifying the driver that the vehicle 1 is displaced from the home position. The driver who sees this performs a steering operation so that the vehicle 1 travels at an appropriate position on the road 2.
同図中表示セグメント５１は、車両１が道路２上の発電コイル４による発電に最適な位置にある場合に表示され、また表示セグメント５２ａは最適な位置より左に、表示セグメント５２ｂは最適な位置より右にずれていることを示している。また表示セグメント５２ａ若しくは５２ｂが表示されている数によってずれた量を表している。例えば図５の例では、表示セグメント５１ａが２つ表示さているので、車両１は左に中程度ずれていることを示している。これを見た運転者は車両１のハンドルを右に切って表示セグメント５１が点灯するように車両１を操作することにより、車両１を道路２上の最適な位置を走行するように位置補正を行う。 The display segment 51 in the figure is displayed when the vehicle 1 is in an optimal position for power generation by the power generation coil 4 on the road 2, the display segment 52a is on the left of the optimal position, and the display segment 52b is the optimal position It shows that it is shifted to the right. Further, the amount of shift is represented by the number of display segments 52a or 52b being displayed. For example, in the example of FIG. 5, since two display segments 51a are displayed, it indicates that the vehicle 1 is shifted to the left moderately. The driver who has seen this operation turns the steering wheel of the vehicle 1 to the right and operates the vehicle 1 so that the display segment 51 is lit, thereby correcting the position so that the vehicle 1 travels at an optimal position on the road 2. Do.
なお図５の例では、検出部４２からの検出結果に基づく通知を表示によって運転者に通知していたが、車両１からの通知の仕方は図５のような視覚によるものに限らず、音声によって通知したり、視覚と音声の両方で運転者に通知するようにしても良い。 In the example of FIG. 5, the notification based on the detection result from the detection unit 42 is notified to the driver by display. However, the notification method from the vehicle 1 is not limited to the visual way as in FIG. Or the driver may be notified both visually and by voice.
また車両１が、自動運転機能を備えるときは、検出部４２による検出結果を運転者に通知すると共に、自動的に車輪を駆動して車両１が道路２上の適宜な位置を走行するように操作するようにしても良い。 Further, when the vehicle 1 has an automatic driving function, the detection result by the detection unit 42 is notified to the driver, and the wheels are automatically driven so that the vehicle 1 travels at an appropriate position on the road 2. You may make it operate.
