- each process of the charging method is executed while the vehicle 100 is traveling on a highway.
- each process of the charging method is repeatedly executed by an interruption that occurs at a predetermined time interval (for example, every 5 minutes). Each process will be described below.
- the calculation unit 212 calculates the required remaining capacity based on the destination information, the vehicle information, the power consumption information, the environmental information, and the road information. For example, the calculation unit 212 calculates the required remaining capacity based on the destination information. The calculation unit 212 may also correct the required remaining capacity based on various information, for example.
- the calculation unit 212 calculates the correction amount based on the vehicle information. For example, when the load on the vehicle 100 is large, the power consumption of the battery 110 increases. Therefore, the calculation unit 212 calculates the amount of power consumption that increases due to the load on the vehicle 100 as a correction amount based on the vehicle information. Then, the calculation unit 212 adds this correction amount to the required remaining capacity.
- the calculation unit 212 calculates the correction amount based on the power consumption information. For example, the calculation unit 212 calculates the power consumption indicated in the power consumption information as the correction amount. Then, the calculation unit 212 adds the correction amount to the required remaining capacity.
- the calculation unit 212 calculates the correction amount based on environmental information.
- the calculation unit 212 calculates the correction amount based on weather information as environmental information. For example, if it is raining or snowing, it is assumed that the wipers will be operated. Therefore, when the weather information indicates rain or snow, the calculation unit 212 calculates the amount of wiper operation as the correction amount. Then, the calculation unit 212 adds this correction amount to the required remaining capacity.
- the calculation unit 212 also calculates the correction amount based on, for example, time information as environmental information. For example, if it is nighttime, it is assumed that the headlights will be operated. Therefore, when the time information indicates nighttime, the calculation unit 212 calculates the amount of headlight operation as the correction amount. Then, the calculation unit 212 adds this correction amount to the required remaining capacity.
- the calculation unit 212 calculates the correction amount based on road information.
- the calculation unit 212 calculates the correction amount based on congestion information as road information. For example, if there is congestion, it is assumed that the power consumption of the battery 110 will increase. For this reason, when the calculation unit 212 acquires congestion information, it calculates the increase in the power consumption of the battery 110 as the correction amount. Then, the calculation unit 212 adds this correction amount to the required remaining capacity.
- the calculation unit 212 also calculates the correction amount based on, for example, gradient information as road information. For example, when traveling on an upward gradient, the power consumption of the battery 110 increases. For this reason, when the road information is gradient information indicating an upward gradient, the calculation unit 212 calculates the increase in power consumption of the battery 110 as the correction amount. The calculation unit 212 then adds this correction amount to the required remaining capacity. For example, when traveling on a downward gradient, the battery 110 can regenerate, so that the decrease in the remaining capacity of the battery 110 is suppressed by the amount of regenerated power. For this reason, when the road information is gradient information indicating a downward gradient, the calculation unit 212 calculates the amount of regenerated power as the correction amount. The calculation unit 212 then subtracts this correction amount from the required remaining capacity.
- gradient information for example, when traveling on an upward gradient, the power consumption of the battery 110 increases. For this reason, when the road information is gradient information indicating an upward gradient, the calculation unit 212 calculates the increase in power consumption of the battery 110 as the correction
- the calculation unit 212 may arbitrarily combine the calculation of the correction amount based on the vehicle information, the calculation of the correction amount based on the power consumption information, the calculation of the correction amount based on the environmental information, and the calculation of the correction amount based on the road information.
- the determination unit 214 determines whether the current remaining capacity is equal to or less than the required remaining capacity. As a result, if the determination unit 214 determines that the current remaining capacity is not equal to or less than the required remaining capacity, that is, that the current remaining capacity exceeds the required remaining capacity (NO in S112), the determination unit 214 shifts the process to prohibition processing S114. On the other hand, if the determination unit 214 determines that the current remaining capacity is equal to or less than the required remaining capacity (YES in S112), the determination unit 214 shifts the process to fee information acquisition processing S116.
- the power receiving control unit 216 prohibits the vehicle 100 from traveling in the wireless charging lane. As a result, the vehicle 100 travels in a travel lane other than the wireless charging lane.
- the acquisition unit 210 extracts wireless charging lanes installed within a reachable range. Then, the acquisition unit 210 acquires information indicating the fees for the extracted wireless charging lanes from an external server.
- the acquisition unit 210 also extracts charging facilities installed within a reachable range. The acquisition unit 210 then acquires information indicating the fees and availability of the extracted charging facilities from an external server.
- the determination unit 214 controls the display unit 130 or a speaker (not shown) to notify the driver of whether or not he intends to stop at the rest area.
- the driver can input information indicating whether or not he intends to stop at the rest area using the operation unit 120.
- the acquisition unit 210 acquires information indicating that the driver intends to stop at the rest area as rest schedule information (YES in S120)
- the determination unit 214 shifts the process to the prohibition process S114.
- the control device 140 reserves the charging equipment provided in the rest area.
- the acquisition unit 210 acquires information indicating that the driver does not intend to stop at the rest area (NO in S120)
- the determination unit 214 shifts the process to the second fee determination process S122.
- Determination unit 214 determines whether the fee of a charging facility that is provided on a general road and that is capable of charging when vehicle 100 arrives is equal to or less than the fee of the wireless charging lane, among the extracted charging facilities. If the result is that the fee of the charging facility is not equal to or less than the fee of the wireless charging lane, that is, the fee of the charging facility exceeds the fee of the wireless charging lane (NO in S122), determination unit 214 ends the charging method. On the other hand, if it is determined that the fee of the charging facility is equal to or less than the fee of the wireless charging lane (YES in S122), processing proceeds to general road permission determination processing S124.
- the determination unit 214 controls the display unit 130 or a speaker (not shown) to notify the driver of whether or not he intends to exit the expressway onto a general road.
- the driver can input information indicating whether or not he intends to exit the expressway onto a general road using the operation unit 120.
- the acquisition unit 210 acquires information indicating that the driver intends to exit the expressway onto a general road as general road schedule information (YES in S124)
- the determination unit 214 moves the process to the prohibition process S114.
- the control device 140 reserves a charging facility provided on a general road.
- the determination unit 214 ends the charging method.
- Determination unit 214 determines whether the fee of a charging facility that is provided on a plurality of branch roads branching off from a branch point on a highway and that is capable of charging when vehicle 100 arrives is equal to or less than the fee of the wireless charging lane. If the result shows that the fee of the charging facility is not equal to or less than the fee of the wireless charging lane, that is, the fee of the charging facility exceeds the fee of the wireless charging lane (NO in S126), determination unit 214 ends the charging method. On the other hand, if it is determined that the fee of the charging facility is equal to or less than the fee of the wireless charging lane (YES in S126), processing proceeds to branch road permission determination processing S128.
- the control device 140 determines whether or not to prohibit driving in the wireless charging lane based on future behavior information of the driver of the vehicle 100. Therefore, the control device 140 can appropriately prohibit driving in the wireless charging lane depending on the driver's future behavior. For example, when the fee for the wireless charging lane is higher than the fee for the charging facility that the vehicle 100 will visit in the future, it is possible to prevent unnecessary driving in the wireless charging lane. Therefore, the control device 140 can reach the destination while charging at low cost.
- the battery 110 is more susceptible to deterioration when it is charged in a wireless charging lane than when it is charged using a charging facility. Therefore, the control device 140 can suppress deterioration of the battery 110 by appropriately prohibiting driving in a wireless charging lane depending on the driver's future actions.

In addition, the control device 140 reserves charging facilities equipped on the branch road.

- the state information of the driver is, for example, the degree of fatigue, the degree of hunger, or the like of the driver.
- the acquisition unit 210 acquires driver status information from a smart watch or the like carried by the driver and determines whether the driver's fatigue level is equal to or greater than a predetermined value.

車両のバッテリの充電を制御する制御装置であって、
前記制御装置は、
1つまたは複数のプロセッサと、
前記プロセッサに接続される1つまたは複数のメモリと、
を有し、
前記プロセッサは、
前記車両のドライバの将来の行動情報に基づいて、ワイヤレス充電レーンの走行、または、前記ワイヤレス充電レーンからの受電を禁止するか否かを判定することを含む処理を実行する。
続いて、上記車両100の充電方法について説明する。図3は、本実施形態に係る充電方法の処理の流れを示す第1のフローチャートである。図4は、本実施形態に係る充電方法の処理の流れを示す第2のフローチャートである。図3、図4に示すように、本実施形態に係る充電方法は、必要残存容量演算処理S110、比較処理S112、禁止処理S114、料金情報取得処理S116、第1料金判定処理S118、休憩許可判定処理S120、第2料金判定処理S122、一般道路許可判定処理S124、第3料金判定処理S126、分岐道路許可判定処理S128を含む。本実施形態において、充電方法の各処理は、車両100が高速道路を走行中に実行される。また、本実施形態において、所定の時間間隔毎(例えば、5分毎)に生じる割込によって、充電方法の各処理が繰り返し実行される。以下、各処理について説明する。
演算部212は、目的地情報、車両情報、消費電力情報、環境情報、道路情報に基づいて、必要残存容量を演算する。例えば、演算部212は、目的地情報に基づいて、必要残存容量を演算する。また、演算部212は、例えば、各種情報に基づいて、必要残存容量を補正してもよい。
判定部214は、現在の残存容量が必要残存容量以下であるか否かを判定する。その結果、現在の残存容量が必要残存容量以下ではない、つまり、現在の残存容量が必要残存容量を上回ると判定した場合(S112におけるNO)、判定部214は、禁止処理S114に処理を移す。一方、現在の残存容量が必要残存容量以下であると判定した場合(S112におけるYES)、判定部214は、料金情報取得処理S116に処理を移す。
受電制御部216は、ワイヤレス充電レーンの走行を禁止する。そうすると、車両100は、ワイヤレス充電レーン以外の走行レーンを走行する。
取得部210は、到達可能範囲内に設置されているワイヤレス充電レーンを抽出する。そして、取得部210は、外部サーバから、抽出したワイヤレス充電レーンの料金を示す情報を取得する。
判定部214は、抽出された充電設備のうち、休憩エリアに設けられた充電設備であって、車両100の到達時に充電可能である充電設備の料金が、ワイヤレス充電レーンの料金以下であるか否かを判定する。その結果、充電設備の料金が、ワイヤレス充電レーンの料金以下ではない、つまり、充電設備の料金がワイヤレス充電レーンの料金を上回る場合(S118におけるNO)、判定部214は、当該充電方法を終了する。一方、充電設備の料金が、ワイヤレス充電レーンの料金以下であると判定した場合(S118におけるYES)、休憩許可判定処理S120に処理を移す。
判定部214は、表示部130または不図示のスピーカを制御して、休憩エリアに立ち寄る意図を有しているか否かをドライバに質問する報知を行う。ここで、ドライバは操作部120を用いて、休憩エリアに立ち寄る意図を有しているか否かを示す情報を入力できる。そして、取得部210が、ドライバが休憩エリアに立ち寄る意図を有していることを示す情報を休憩予定情報として取得したら(S120におけるYES)、判定部214は、禁止処理S114に処理を移す。また、制御装置140は、休憩エリアに設けられた充電設備を予約する。一方、取得部210が、ドライバが休憩エリアに立ち寄る意図を有していないことを示す情報を取得した場合(S120におけるNO)、判定部214は、第2料金判定処理S122に処理を移す。
判定部214は、抽出された充電設備のうち、一般道路に設けられた充電設備であって、車両100の到達時に充電可能である充電設備の料金が、ワイヤレス充電レーンの料金以下であるか否かを判定する。その結果、充電設備の料金が、ワイヤレス充電レーンの料金以下ではない、つまり、充電設備の料金がワイヤレス充電レーンの料金を上回る場合(S122におけるNO)、判定部214は、当該充電方法を終了する。一方、充電設備の料金が、ワイヤレス充電レーンの料金以下であると判定した場合(S122におけるYES)、一般道路許可判定処理S124に処理を移す。
判定部214は、表示部130または不図示のスピーカを制御して、高速道路から一般道路に降りる意図を有しているか否かをドライバに質問する報知を行う。ここで、ドライバは操作部120を用いて、高速道路から一般道路に降りる意図を有しているか否かを示す情報を入力できる。そして、取得部210が、ドライバが高速道路から一般道路に降りる意図を有していることを示す情報を一般道路予定情報として取得したら(S124におけるYES)、判定部214は、禁止処理S114に処理を移す。また、制御装置140は、一般道路に設けられた充電設備を予約する。一方、取得部210が、ドライバが高速道路から一般道路に降りる意図を有していないことを示す情報を取得した場合(S124におけるNO)、判定部214は、当該充電方法を終了する。
判定部214は、抽出された充電設備のうち、高速道路の分岐箇所から分岐された複数の分岐道路に設けられた充電設備であって、車両100の到達時に充電可能である充電設備の料金が、ワイヤレス充電レーンの料金以下であるか否かを判定する。その結果、充電設備の料金が、ワイヤレス充電レーンの料金以下ではない、つまり、充電設備の料金がワイヤレス充電レーンの料金を上回る場合(S126におけるNO)、判定部214は、当該充電方法を終了する。一方、充電設備の料金が、ワイヤレス充電レーンの料金以下であると判定した場合(S126におけるYES)、分岐道路許可判定処理S128に処理を移す。
判定部214は、表示部130または不図示のスピーカを制御して、高速道路の分岐箇所から分岐された複数の分岐道路のうち、充電設備が設けられた分岐道路へ進む意図を有しているか否かをドライバに質問する報知を行う。ここで、ドライバは操作部120を用いて、高速道路から分岐道路へ進む意図を有しているか否かを示す情報を入力できる。そして、取得部210が、ドライバが高速道路から分岐道路に進む意図を有していることを示す情報を分岐道路予定情報として取得したら(S128におけるYES)、判定部214は、禁止処理S114に処理を移す。また、制御装置140は、分岐道路に設けられた充電設備を予約する。一方、取得部210が、ドライバが高速道路から分岐道路へ進む意図を有していないことを示す情報を取得した場合(S128におけるNO)、判定部214は、当該充電方法を終了する。
上記実施形態では、取得部210が、ドライバの操作入力に基づいて、将来の行動情報を取得する場合を例に挙げた。しかし、取得部210は、車両100の走行ルートに基づいて、将来の行動情報を取得してもよい。
また、取得部210は、渋滞情報に基づいて、将来の行動情報を取得してもよい。
また、取得部210は、車両100のドライバの状態情報に基づいて、将来の行動情報を取得してもよい。ドライバの状態情報は、例えば、ドライバの疲労度、空腹度等である。
