Description

走行制御装置Travel control device
　本発明は、太陽電池パネルを搭載した車両の走行制御装置に関する。 The present invention relates to a travel control device for a vehicle equipped with a solar cell panel.
　近年、電気自動車（ＥＶ）やプラグインハイブリッド車（ＰＨＥＶ）など電気を動力とする車両がある。このような車両に太陽電池パネルを搭載して日向に駐車することにより太陽光発電を行い、充電池に充電することができる。しかし、駐車した場所が日陰だと太陽光発電ができず、別途電源を用いて充電する必要がある。 In recent years, there are vehicles powered by electricity, such as electric vehicles (EV) and plug-in hybrid vehicles (PHEV). By mounting a solar battery panel on such a vehicle and parking in the sun, solar power can be generated and the rechargeable battery can be charged. However, if the place where you parked is in the shade, you will not be able to generate solar power, and you will need to charge it separately using a power source.
　特許文献１には、駐車スペース検索の際に最も日射量が多いと推定される候補駐車場を、日時、天候、候補駐車場周辺の建築物などの要因に基づいて算出し、ユーザに知らせる移動体用装置の技術が提案されている。 In Patent Document 1, a candidate parking lot that is estimated to have the largest amount of solar radiation when searching for a parking space is calculated based on factors such as date and time, weather, buildings around the candidate parking lot, and the like to inform the user Techniques for body devices have been proposed.

　上記の従来装置による移動体用装置では、事前の推定に基づき駐車後に最も日射量が多いと推定される駐車場を推奨するが、車両利用者の目的地と推奨された駐車場とが一致するとは限らない。例えば推奨された駐車場が車両利用者の目的地と離れていた場合には、推奨された駐車場への駐車が躊躇され、目的地には近いが太陽光発電による充電が行われない駐車場に駐車されるおそれがあり、かかる場合には別途電源を用いて充電が行われ、充電コストが嵩むことになる。 In the above-mentioned conventional apparatus for a mobile unit, a parking lot that is estimated to have the highest amount of solar radiation after parking is recommended based on a prior estimation, but the vehicle user's destination matches the recommended parking lot. Is not limited. For example, if the recommended parking lot is far from the destination of the vehicle user, parking at the recommended parking lot is deceived and the parking lot is close to the destination but not charged by solar power generation In such a case, charging is performed using a separate power source, which increases the charging cost.
　本発明は、上記の点に鑑みてなされたものであり、その目的とするところは、利用者が車両を利用する前、あるいは目的地に到着した後等、車両を運転しない時間帯を、太陽電池パネルを用いた太陽光発電に利用することができる走行制御装置を提供することにある。 The present invention has been made in view of the above points, and the object of the present invention is to provide a time zone during which the vehicle is not driven, such as before the user uses the vehicle or after arriving at the destination.

　図２は、本実施形態の走行制御装置による制御内容を説明するフローチャートである。
　走行制御装置１０１は、車両の利用者が車両を利用しておらず、車両が自車位置から予め設定された太陽光発電場所に移動した方が移動しないよりも太陽電池パネルの太陽光発電により充電池に充電されると予想される予想充電量が多く、かつ、太陽光発電場所における予想充電量が、自車位置から太陽光発電場所まで往復走行した際の充電消費量、もしくは、自車位置から太陽光発電場所を経由して予め設定された帰着場所まで走行した際の充電消費量よりも多い場合に、車両を太陽光発電場所まで走行させる自動運転制御を行う。 FIG. 2 is a flowchart for explaining the contents of control by the travel control device of this embodiment.
The travel control device 101 uses solar power generation of a solar panel rather than a vehicle user who does not use the vehicle and does not move when the vehicle moves from a vehicle position to a preset solar power generation location. The amount of charge expected to be charged in the rechargeable battery is large, and the estimated amount of charge at the solar power generation site is the charge consumption when traveling back and forth from the own vehicle position to the solar power generation site, or the own vehicle When the amount of charge is greater than the amount of charge consumed when traveling from a position to a preset return location via a solar power generation location, automatic driving control is performed to cause the vehicle to travel to the solar power generation location.
　以下、走行制御装置１０１の具体的な制御処理の内容について説明する。
　まず、ステップＳ１０１では、太陽光発電が可能な発電可能場所の問い合わせが行われる。走行制御装置１０１は、例えば現在時刻が車両の利用者が車両を利用しないとして予め設定された設定時間であると判断した場合に、カーナビゲーション通信装置１０７の通信制御部により問い合わせの無線通信を行い、無線通信網を介して発電可能場所の情報を取得する。発電可能場所とは、かかる場所に駐車することによって太陽電池パネルに太陽光を受けて太陽光発電を行うことができる場所を示す。 Hereinafter, the content of the specific control processing of the traveling control apparatus 101 will be described.
First, in step S101, an inquiry is made about a place where power generation is possible where solar power generation is possible. For example, when the travel control device 101 determines that the current time is a preset time that the user of the vehicle does not use the vehicle, the communication control unit of the car navigation communication device 107 performs wireless communication for inquiry. Then, information on a place where power can be generated is acquired via a wireless communication network. The place where power generation is possible refers to a place where solar power generation can be performed by receiving sunlight on the solar cell panel by parking in such a place.
　そして、ステップＳ１０２では、ステップＳ１０１の問い合わせにより取得した情報に基づき、発電場所（太陽光発電場所）を決定する。発電場所では、太陽電池パネルに太陽光を当てることができなければならないので、発電場所は天気の情報や日照時間も考慮して決定される。なるべく近くかつ日当たりの良い場所が発電場所として決定される。なお、太陽の位置に対する車両の向きによっても発電量が異なってくるので、車両の向きも併せて考慮して発電場所を決定してもよい。 And in step S102, based on the information acquired by the inquiry of step S101, a power generation place (solar power generation place) is determined. In the power generation place, since it is necessary to be able to shine sunlight on the solar cell panel, the power generation place is determined in consideration of weather information and sunshine hours. A place that is as close and sunny as possible is determined as the power generation site. Since the amount of power generation varies depending on the direction of the vehicle with respect to the sun position, the power generation location may be determined in consideration of the direction of the vehicle.
　ステップＳ１０３では、車両が自車の現在位置からステップＳ１０２で決定された発電場所に移動した方が移動しないよりも太陽電池パネルの太陽光発電により充電池に充電されると予想される予想充電量が多いか否かが判断される。現在位置と発電場所における予想充電量は、それぞれの場所の日照時間や天気予報の情報に基づいて算出される。 In step S103, the expected charge amount that the rechargeable battery is expected to be charged by solar power generation of the solar panel rather than not moving when the vehicle moves from the current position of the vehicle to the power generation location determined in step S102. It is determined whether or not there are many. The expected charge amount at the current position and the power generation location is calculated based on the sunshine hours and weather forecast information at each location.
　そして、発電場所の予想充電量の方が現在位置よりも多いと予想された場合には(ステップＳ１０３でＹＥＳ)、ステップＳ１０４に移行し、発電場所における予想充電量が、自車位置から発電場所まで往復走行した際の充電消費量、もしくは、自車位置から発電場所を経由して予め設定された帰着場所まで走行した際の充電消費量よりも多いか否かが判断される。充電消費量は、例えば現在位置から発電場所または帰着場所までの距離と、坂道やカーブなどの道路形状の情報に基づいて算出される。距離と道路形状の情報は、カーナビゲーション通信装置１０７から取得する。 If it is predicted that the estimated charging amount at the power generation location is larger than the current position (YES in step S103), the process proceeds to step S104, where the predicted charging amount at the power generation location is changed from the own vehicle position to the power generation location. It is determined whether or not the charging consumption is greater than the charging consumption when traveling back and forth, or the charging consumption when traveling from the vehicle position to a preset return location via the power generation location. The charge consumption is calculated based on, for example, the distance from the current position to the power generation place or the return place, and information on road shapes such as slopes and curves. Information on the distance and the road shape is acquired from the car navigation communication device 107.
　ステップＳ１０４で発電場所における予想充電量が上記の充電消費量よりも多い場合には(ステップＳ１０４でＹＥＳ)、車両を発電場所まで移動させて太陽光発電による充電を行うべく、ステップＳ１０５以降に移行する。 If the estimated charge amount at the power generation site is larger than the above-mentioned charge consumption amount at step S104 (YES at step S104), the process proceeds to step S105 and subsequent steps so that the vehicle is moved to the power generation site and charged by solar power generation. To do.
　一方、発電場所に移動しても移動しないより充電できない場合や(ステップＳ１０３でＮＯ）、発電場所における予想充電量が充電消費量以下の場合には（ステップＳ１０４でＮＯ）、移動してしまうと却って充電量が減ってしまうので、ステップＳ１０９で現在位置のまま移動せず、一定時間待機し、所定時間経過後に再びステップＳ１０１からの判断処理を行う。 On the other hand, if it is not possible to charge even if it moves to the power generation place (NO in step S103), or if the expected charge amount in the power generation place is equal to or less than the charge consumption amount (NO in step S104), On the other hand, the amount of charge is reduced, so that the current position is not moved in step S109, the apparatus waits for a certain time, and the determination process from step S101 is performed again after a predetermined time has elapsed.
　ステップＳ１０５では、車両を発電場所に移動させ、太陽光発電を開始する処理が行われる。走行制御装置１０１は、カーナビゲーション通信装置１０７による経路案内と、車両周辺センサ１０５からの検出情報に基づき、アクチュエータ１０６を制御し、車両を発電位置まで走行させる自動運転制御を行う。そして、車両を発電場所に駐車させ、太陽電池パネル１０３による太陽光発電を開始し、充電池１０４に充電する。
　そして、ステップＳ１０６では、予め設定された上限量まで充電池１０４が充電された、いわゆるフル充電の状態となった場合に、充電池１０４への充電を終了する処理が行われる。電池制御部１０２は、充電池１０４が上限量まで充電されたことを確認し、走行制御装置１０１にその情報を伝える。走行制御装置１０１は、電池制御部１０２に充電終了を指示し、電池制御部１０２は、充電池１０４への充電を終了させる。 In step S105, a process of moving the vehicle to the power generation place and starting solar power generation is performed. The travel control device 101 controls the actuator 106 based on the route guidance by the car navigation communication device 107 and the detection information from the vehicle periphery sensor 105, and performs automatic driving control that causes the vehicle to travel to the power generation position. Then, the vehicle is parked at the power generation place, solar power generation by the solar battery panel 103 is started, and the rechargeable battery 104 is charged.
In step S106, when the rechargeable battery 104 is charged to a preset upper limit amount, that is, in a so-called full charge state, a process for terminating the charging of the rechargeable battery 104 is performed. The battery control unit 102 confirms that the rechargeable battery 104 has been charged to the upper limit amount, and notifies the traveling control device 101 of the information. The travel control apparatus 101 instructs the battery control unit 102 to end charging, and the battery control unit 102 ends charging of the rechargeable battery 104.
　ステップＳ１０７では、車両を走行させて、元の駐車場所、もしくは予め設定された別の帰着場所まで移動させる処理が行われる。走行制御装置１０１は、カーナビゲーション通信装置１０７による経路案内と、車両周辺センサ１０５からの検出情報に基づき、アクチュエータ１０６を制御し、車両を元の駐車位置もしくは別の帰着位置まで走行させる自動運転制御を行う。 In step S107, a process of moving the vehicle to the original parking place or another return place set in advance is performed. The travel control device 101 controls the actuator 106 based on the route guidance by the car navigation communication device 107 and the detection information from the vehicle periphery sensor 105, and causes the vehicle to travel to the original parking position or another return position. I do.
　そして、ステップＳ１０８では、上述した一連の充電モードを解除するか否かが判断される。充電モードを解除するか否かは、車両の利用者が予め設定しておくことができる。例えば定期的に自動充電を行いたい場合には充電モードは解除しないが、単発的に充電を行いたい場合には、自動充電後に充電モードを解除する。 In step S108, it is determined whether or not to cancel the series of charging modes described above. Whether or not to release the charging mode can be preset by the user of the vehicle. For example, when it is desired to perform automatic charging periodically, the charging mode is not canceled, but when charging is desired to be performed once, the charging mode is canceled after automatic charging.
　図３は、実施例１の内容を説明する図である。
　本実施例の車両３１１は、図１に示す構成を有するＥＶまたはＰＨＥＶである。本実施例では、車両３１１の利用者が車両３１１を利用しない時間帯に、車両３１１が自動運転により自宅駐車場３０１を出発し、道路３０３を通行して日当たりのよい平面駐車場３０２まで走行する。そして、平面駐車場３０２に駐車して太陽光発電を行い、充電池をフル充電した後、再び道路３０３を通行して自宅駐車場３０１に戻る動作を行う。 FIG. 3 is a diagram for explaining the contents of the first embodiment.
The vehicle 311 of the present embodiment is an EV or PHEV having the configuration shown in FIG. In this embodiment, the vehicle 311 departs from the home parking lot 301 by automatic driving and travels to the sunny flat parking lot 302 through the road 303 during a time period when the user of the vehicle 311 does not use the vehicle 311. . And it parks in the plane parking lot 302, performs solar power generation, fully charges the rechargeable battery, and then goes through the road 303 again and returns to the home parking lot 301.
　車両３１１の走行制御装置１０１は、カーナビゲーション通信装置１０７の通信制御部により無線通信を行い、無線通信網を介して発電可能場所の情報を取得する。例えば車両３１１が駐車している自宅駐車場３０１は、家の影になり、日が当たらない時間帯がある一方、自宅駐車場３０１から離れた平面駐車場３０２は、自宅駐車場３０１よりも日当たりがよい、という情報を取得する。したがって、自宅駐車場３０１ではなく、平面駐車場３０２を発電場所として決定する。 The traveling control device 101 of the vehicle 311 performs wireless communication by the communication control unit of the car navigation communication device 107, and acquires information on a place where power generation is possible via the wireless communication network. For example, the home parking lot 301 where the vehicle 311 is parked is a shadow of the house and there is a time zone where the sun does not hit, while the flat parking lot 302 away from the home parking lot 301 is more sunny than the home parking lot 301 Get information that is good. Therefore, not the home parking lot 301 but the plane parking lot 302 is determined as the power generation place.
　そして、現在時刻や天気情報、移動距離、道路形状等の情報に基づき、車両３１１が移動した方が移動しないよりも充電できる充電量が多いか否かを判断する。ここでは、平面駐車場３０２で充電される充電量が多く、平面駐車場３０２に移動した方が自宅駐車場３０１よりも充電できると判断する。 Then, based on information such as the current time, weather information, travel distance, road shape, etc., it is determined whether the amount of charge that can be charged is greater when the vehicle 311 moves than when it does not move. Here, the amount of charge charged in the flat parking lot 302 is large, and it is determined that the person moving to the flat parking lot 302 can charge more than the home parking lot 301.
　次に、道路３０３を通行して自宅駐車場３０１と平面駐車場３０２との間を往復移動する際に消費される充電消費量と平面駐車場３０２で充電される予想充電量とを比較する。そして、予想充電量が充電消費量を上回るときは、道路３０３を通行して平面駐車場３０２まで車両３１１を走行させ、平面駐車場３０２で太陽光発電により充電を行わせ、フル充電後に、再び道路３０３を通行させて自宅駐車場３０１に戻らせる。 Next, the amount of charge consumed when traveling on the road 303 and reciprocating between the home parking lot 301 and the flat parking lot 302 is compared with the expected charge charged in the flat parking lot 302. When the estimated charge amount exceeds the charge consumption amount, the vehicle 311 is traveled to the flat parking lot 302 through the road 303 and charged by solar power generation in the flat parking lot 302. Let the road 303 pass and return to the home parking lot 301.
　したがって、車両３１１の利用者が車両３１１を利用しない時間帯を、太陽電池パネルを用いた太陽光発電に利用することができ、別途電源による充電を行う必要がなく、充電コストを下げることができる。 Therefore, the time zone when the user of the vehicle 311 does not use the vehicle 311 can be used for solar power generation using the solar battery panel, and it is not necessary to separately charge with a power source, and the charging cost can be reduced. .
　図４は、実施例２の内容を説明する図である。
　本実施例では、午前と午後で日向の位置が変わる自宅駐車場で、車両３１１の充電量が足りない場合に、日向の位置を追いかけるように車両３１１が移動して太陽光発電により充電を行い、フル充電後は日陰の位置に移動する動作を行う。 FIG. 4 is a diagram for explaining the contents of the second embodiment.
In the present embodiment, when the amount of charge of the vehicle 311 is insufficient in a home parking lot where the position of the sun changes between morning and afternoon, the vehicle 311 moves to follow the position of the sun and is charged by solar power generation. After full charge, move to the shaded position.
　午前中は太陽４０１ａと樹木４０２の位置により自宅駐車場３０１の後半部分３０１ｂが日陰となっており、車両３１１は、日向となっている自宅駐車場３０１の前半部分３０１ａに駐車し、太陽光発電を行っている。 In the morning, the second half portion 301b of the home parking lot 301 is shaded by the position of the sun 401a and the tree 402, and the vehicle 311 is parked in the first half portion 301a of the home parking lot 301 that is facing the sun. It is carried out.
　そして、午後になると、太陽４０１ｂと樹木４０３の位置により自宅駐車場３０１の前半部分３０１ａが日陰になり、車両３１１は、日陰である自宅駐車場３０１の前半部分３０１ａに入ってしまう。 In the afternoon, the first half portion 301a of the home parking lot 301 becomes shaded due to the positions of the sun 401b and the tree 403, and the vehicle 311 enters the first half portion 301a of the shaded home parking lot 301.
　走行制御装置１０１は、太陽光発電により充電池がフル充電されていないのに車両３１１が日陰に入った場合に、車両３１１を日向に移動させる制御を行う。
　本実施例では、駐車場の前半部分３０１ａから後半部分３０１ｂに車両３１１を移動させる。したがって、車両３１１は、充電池をフル充電することができる。したがって、利用者が車両３１１を利用していない時間帯に、太陽光発電により充電池１０４を充電することができる。 The travel control device 101 performs control to move the vehicle 311 in the sun when the vehicle 311 enters the shade even though the rechargeable battery is not fully charged by solar power generation.
In this embodiment, the vehicle 311 is moved from the first half 301a to the second half 301b of the parking lot. Therefore, the vehicle 311 can fully charge the rechargeable battery. Therefore, the rechargeable battery 104 can be charged by solar power generation during a time period when the user is not using the vehicle 311.
　そして、走行制御装置１０１は、フル充電後に車両３１１を日陰である自宅駐車場３０１の前半部分３０１ａに移動させる。したがって、車両３１１の車内が高温になるのを防ぎ、また、太陽電池パネルの劣化を防ぐことができる。なお、自宅駐車場内における日向日陰の位置情報は、カーナビゲーション通信装置１０７から取得してもよいし、また、利用者が直接入力してもよい。 And the traveling control apparatus 101 moves the vehicle 311 to the first half part 301a of the home parking lot 301 which is shaded after full charge. Therefore, the inside of the vehicle 311 can be prevented from becoming hot, and the solar cell panel can be prevented from deteriorating. Note that the position information of the shade in the home parking lot may be acquired from the car navigation communication device 107 or may be directly input by the user.
　図５は、実施例３の内容を説明する図である。
　本実施例は、車両５１１と立体駐車施設５０２を用いた駐車システムである。車両５１１は、上述の実施例１、２と同様に、図１に示す構成を有するＥＶまたはＰＨＥＶである。立体駐車施設５０２は、車両５１１が駐車した状態で太陽電池パネル１０３が太陽光発電可能な太陽光発電場所となる日向の屋上駐車場５２３と、太陽電池パネル１０３が太陽光発電不可能な非発電場所となる日陰の階下駐車場５２２を有する。 FIG. 5 is a diagram for explaining the contents of the third embodiment.
The present embodiment is a parking system using a vehicle 511 and a multistory parking facility 502. The vehicle 511 is an EV or PHEV having the configuration shown in FIG. 1 as in the first and second embodiments. The multi-story parking facility 502 includes a Hinata rooftop parking lot 523, which is a solar power generation place where the solar battery panel 103 is capable of solar power generation in a state where the vehicle 511 is parked, and non-power generation where the solar battery panel 103 is not capable of solar power generation. It has a shaded downstairs parking lot 522 as a place.
　本実施例では、日向となる屋上駐車場５２３と、日陰となる途中階の階下駐車場５２２とを有する自走式の立体駐車施設５０２において、階下駐車場５２２に駐車した車両５１１が、自動運転により階下駐車場５２２を出発し、スロープ５２１を上って日当たりのよい屋上駐車場５２３まで移動する。 In this embodiment, in a self-propelled multilevel parking facility 502 having a rooftop parking lot 523 that is in the sun and a downstairs parking lot 522 that is in the shade, a vehicle 511 parked in the downstairs parking lot 522 is automatically driven. To depart from the downstairs parking 522 and move up the slope 521 to the sunny rooftop parking 523.
　そして、屋上駐車場５２３に駐車して太陽光発電を行い、充電池をフル充電した後、再びスロープ５２１を下って階下駐車場５２２に戻る動作を行う。したがって、例えば立体駐車施設５０２に隣接されたショッピングモール５０１で車両５１１の利用者が買い物をしている間等、車両５１１を運転しない合間に、太陽光発電により車両５１１の充電池１０４を充電することができる。 Then, the vehicle is parked at the rooftop parking lot 523, solar power is generated, the rechargeable battery is fully charged, and then the vehicle returns to the downstairs parking lot 522 by going down the slope 521 again. Therefore, for example, while the user of the vehicle 511 is shopping in the shopping mall 501 adjacent to the multi-story parking facility 502, the rechargeable battery 104 of the vehicle 511 is charged by solar power generation while the vehicle 511 is not driven. be able to.
　立体駐車施設５０２は、屋上駐車場５２３が空いているか否かの発電場所情報を取得する駐車情報取得部５０４と、階下駐車場５２２に駐車している車両５１１に対して発電場所情報を送信する送信部５０３を有している。 The multi-story parking facility 502 transmits the power generation location information to the parking information acquisition unit 504 that acquires the power generation location information indicating whether or not the rooftop parking lot 523 is vacant, and the vehicle 511 parked in the downstairs parking lot 522. A transmission unit 503 is included.
　階下駐車場５２２に駐車している車両５１１は、カーナビゲーション通信装置１０７によって発電場所情報を受信すると（受信部）、走行制御装置１０１により自動運転制御を行うか否かを判断する。 When the vehicle 511 parked in the downstairs parking lot 522 receives the power generation location information by the car navigation communication device 107 (reception unit), the travel control device 101 determines whether to perform automatic driving control.
　走行制御装置１０１は、階下駐車場５２２の駐車位置から屋上駐車場５２３まで移動した方が移動しないよりも太陽光発電による予想充電量が多く、かつ、予想充電量が、階下駐車場５２２の自車位置と屋上駐車場５２３との間を往復走行した際の充電消費量、もしくは、階下駐車場５２２の自車位置から屋上駐車場５２３を経由して階下駐車場５２２の予め設定された帰着場所まで走行した際の充電消費量よりも多いときは、車両５１１を屋上駐車場５２３まで走行させる自動運転制御を行う。 The travel control device 101 has a higher expected charge amount due to solar power generation when the vehicle moves from the parking position of the downstairs parking lot 522 to the rooftop parking lot 523 and does not move. Charge consumption when traveling back and forth between the vehicle position and the rooftop parking lot 523, or a preset return place of the downstairs parking lot 522 from the own vehicle position of the downstairs parking lot 522 via the rooftop parking lot 523 When the amount of charging is greater than the amount consumed when the vehicle travels to the vehicle, automatic driving control is performed to cause the vehicle 511 to travel to the rooftop parking 523.
