すると、地図表示プログラム３１１２は指定された目的地の位置情報（経度、緯度情報）を経路探索プログラム３１１１に渡す。経路探索プログラム３１１１は位置検出プログラム３１１４がＧＰＳ受信機１０１５による受信電波によって検出している現在位置と利用者が指定した目的地の情報に基づき、現在地から目的地に至る最適経路をデータベース３０５２の道路ネットワーク情報に基づき探索し、その探索結果を表示装置３０３に表示された地図上に合成表示する。
この状態で、目的地周辺における駐車場を予約する場合、携帯情報端末１０１ｂを携帯する利用者は予約プログラム３１１３を起動し、目的地までの到着予定時刻および「当該車両が駐車可能な駐車場タイプの情報」を設定し、目的地＝「東京タワー」付近の最寄の駐車場を予約する操作を行う。予約要求を受け付けた予約プログラム３１１３は、これら駐車場タイプの情報、目的地までの到着予定時刻と共に、利用者ＩＤおよび経路探索プログラム３１１１が探索した経路情報を付加した駐車場予約要求情報をモデム３０８および無線送受信回路３０９を介して駐車場予約サーバ１０４宛に送信する（ステップ６０１，６０２）。 A user who carries the portable information terminal 101b configured by the mobile phone 1014 makes a reservation request by the same operation when he / she gets on the car and heads for the destination.
That is, the route search program 3111, the map display program 3112, and the position detection program 3114 are activated, and the map display program 3112 displays a map of the area including the destination on the display device 303, and the destination is displayed on the displayed map. Is specified by keypad operation. For example, the position of “Tokyo Tower” is designated as the destination.
Then, the map display program 3112 passes the specified destination location information (longitude and latitude information) to the route search program 3111. The route search program 3111 determines the optimum route from the current location to the destination based on the current location detected by the location detection program 3114 using the radio waves received by the GPS receiver 1015 and the destination information designated by the user. The search is performed based on the network information, and the search result is synthesized and displayed on the map displayed on the display device 303.
In this state, when reserving a parking lot in the vicinity of the destination, the user carrying the portable information terminal 101b activates the reservation program 3113, the estimated arrival time to the destination, and the “parking type in which the vehicle can be parked”. "Information" and set the nearest parking lot near destination = "Tokyo Tower". The reservation program 3113 that has received the reservation request sends the parking reservation request information including the user ID and the route information searched by the route search program 3111 together with the information on the parking lot type and the estimated arrival time to the destination to the modem 308. And it transmits to the parking lot reservation server 104 via the wireless transmission / reception circuit 309 (steps 601 and 602).

駐車場予約サーバ１０４の予約プログラム４０９１は、携帯情報端末１０１ａまたは１０１ｂから希望の駐車場タイプ、利用者ＩＤ及び目的地までの到着予定時刻等を付加した予約要求情報を受信した場合（ステップ６０３）、到着予定時刻において予約可能な目的地周辺の駐車場１０７を予約ＤＢ１０３より検索し、利用者が希望する駐車場タイプの予約可能な駐車場があれば、その予約処理を行い、予約ＤＢ１０３に予約登録する（ステップ６０４）。そして、予約した駐車場の名称や位置情報を予約完了通知として要求元の携帯情報端末１０１ａまたは１０１ｂに返却する（ステップ６０５）。
なお、駐車場予約サーバ１０４の予約プログラム４０９１は、最適な駐車場１０７が現時点で存在しない場合、駐車場検索を目的地への到着予定時刻の直前まで繰り返す。そして、到着予定時刻までに空車スペースができ、予約が取れた場合、予約完了通知を携帯情報端末１０１に返信する。
ここで、予約ＤＢ１０６より駐車場１０７を検索する場合、駐車場タイプ、目的地付近かつ到着予定時刻から所定の駐車時間（例えば２時間など）を確保できる空車スペースが存在する駐車場１０７を検索する。 The reservation program 4091 of the parking lot reservation server 104 receives reservation request information to which the desired parking lot type, user ID, estimated arrival time to the destination, etc. are added from the portable information terminal 101a or 101b (step 603). Then, the parking lot 107 near the destination that can be reserved at the estimated arrival time is searched from the reservation DB 103, and if there is a parking lot that can be reserved of the parking type desired by the user, the reservation processing is performed and the reservation DB 103 is reserved. Register (step 604). Then, the name and position information of the reserved parking lot are returned to the requesting portable information terminal 101a or 101b as a reservation completion notice (step 605).
It should be noted that the reservation program 4091 of the parking lot reservation server 104 repeats the parking lot search until just before the estimated arrival time at the destination when the optimum parking lot 107 does not exist at the present time. When an empty space is made by the estimated arrival time and a reservation is made, a reservation completion notice is returned to the portable information terminal 101.
Here, when searching for the parking lot 107 from the reservation DB 106, the parking lot 107 where there is an empty vehicle space that can secure a predetermined parking time (for example, 2 hours) from the parking lot type, the vicinity of the destination, and the estimated arrival time is searched. .

予約完了通知を受信した携帯情報端末１０１ａの予約プログラム２１０３は、予約した駐車場の名称や位置情報を駐車場予約サーバ１０４から受信したならば、その駐車場の一情報を経路探索プログラム２１０１に渡し、新たな目的地として当該駐車場の位置を自動で再設定し（ステップ６０６）、その新たな目的地への経路の再探索を経路探索プログラム２１０１に実行させ、その探索結果の経路を表示装置２０４に表示し、案内誘導を行う（ステップ６０７）。
携帯情報端末１０１ａの位置情報検出プログラム２１０４は、定期的に自車位置の緯度経度をＧＰＳ受信機１０２からの受信電波によって検出し、自車位置の緯度経度情報を予約プログラム２１０３に渡す。予約プログラム２１０３は再探索結果の経路情報と現在位置情報とを駐車場予約サーバ１０４に随時送信する（ステップ６０８）。
携帯電話機１０１４で構成される携帯情報端末１０１ｂにおいても同様に、再探索結果の経路情報と現在位置情報とを駐車場予約サーバ１０４に随時送信する（ステップ６０８）。 When the reservation program 2103 of the portable information terminal 101a that has received the reservation completion notification receives the name and position information of the reserved parking lot from the parking reservation server 104, the reservation program 2103 passes the information on the parking lot to the route search program 2101. Then, the position of the parking lot is automatically reset as a new destination (step 606), the route search program 2101 is caused to re-search for a route to the new destination, and the route of the search result is displayed on the display device. 204, and guidance is provided (step 607).
The position information detection program 2104 of the portable information terminal 101 a periodically detects the latitude and longitude of the own vehicle position from the received radio wave from the GPS receiver 102, and passes the latitude and longitude information of the own vehicle position to the reservation program 2103. The reservation program 2103 transmits the route information and the current position information of the re-search result as needed to the parking lot reservation server 104 (step 608).
Similarly, in the mobile information terminal 101b configured by the mobile phone 1014, the route information and the current position information of the re-search result are transmitted to the parking lot reservation server 104 as needed (step 608).

駐車場予約サーバ１０４は、携帯情報端末１０１ａから現在位置情報と経路情報を受信したならば、現在位置情報が予約ＤＢ１０３に予約登録されている駐車場の位置であるかを判定し（ステップ６０９）、そうであれば、目的の駐車場に到着したことになるので、当該車両に対する処理を終了する。
しかし、現在位置情報が予約ＤＢ１０３に予約登録されている駐車場の位置でなかった場合には、未だ目的の駐車場に到着していないことになるので、交通情報取得プログラム４０９２により携帯情報端末１０１ａから受信した経路情報をもとに交通情報配信サーバ１０５から該当経路上の渋滞等の交通情報を取得し（ステップ６１０）、予約した駐車場１０７までの到着予定時刻を予測計算する（ステップ６１１）。
駐車場予約サーバ１０４は、ステップ６１１で算出された到着予定時刻と、予約ＤＢ１０３に現在登録されている到着予定時刻とを比較し、到着予定時刻が遅れるのか、早まるのかを判定する（ステップ６１２）。
そして、到着予定時刻の遅早に応じて、駐車場予約サーバ１０４が管理している目的地周辺の駐車場における空きスペースを検索し、最適な駐車場に予約を変更する。具体的には、予約ＤＢ１０３に現在登録されている駐車場を新たな駐車場に書き換え、かつ当該駐車場への到着予定時刻を登録する（ステップ６１３）。
この場合、同じ駐車場１０７の別の駐車スペースになる場合もあるが、駐車場予約サーバ１０４に登録されている別の駐車場１０７になる場合もある。 When receiving the current position information and the route information from the portable information terminal 101a, the parking reservation server 104 determines whether the current position information is the position of the parking lot reserved and registered in the reservation DB 103 (step 609). If so, it means that the vehicle has arrived at the target parking lot, and the processing for the vehicle is terminated.
However, if the current position information is not a parking lot position that is reserved and registered in the reservation DB 103, it means that the destination parking lot has not yet been reached. Based on the route information received from the traffic information distribution server 105, traffic information such as traffic congestion on the route is acquired (step 610), and the estimated arrival time to the reserved parking lot 107 is predicted and calculated (step 611). .
The parking lot reservation server 104 compares the estimated arrival time calculated in step 611 with the estimated arrival time currently registered in the reservation DB 103, and determines whether the estimated arrival time is delayed or advanced (step 612). .
And according to the arrival time of the estimated arrival time, an empty space in the parking lot around the destination managed by the parking lot reservation server 104 is searched, and the reservation is changed to the optimum parking lot. Specifically, the parking lot currently registered in the reservation DB 103 is rewritten to a new parking lot, and the estimated arrival time at the parking lot is registered (step 613).
In this case, it may be another parking space of the same parking lot 107, but may be another parking lot 107 registered in the parking lot reservation server 104.

なお、到着予定時刻を予測計算する場合、推奨速度で車両を走行させた場合の所要時間を算出し、その所要時間に渋滞時間を加算した結果を予測所要時間とし、出発時刻に予測所要時間を加算した結果を到着予定時刻として求めるが、ＧＰＳ受信機１０１２による現在位置の更新速度により走行速度を推定し、その推定速度に応じて推奨速度を補正することにより、実際の走行速度を反映した到着予定時刻を算出することができる。
ステップ６１３で別の駐車場１０７に予約変更した場合、携帯情報端末１０１ａに対して目的地となる駐車場１０７の新たな位置情報（緯度経度）を送信する（ステップ６０５）。
携帯情報端末１０１ａ側ではその新たな位置情報を目的地として再設定し（ステップ６０６）、新たな駐車場への案内誘導を行う。 When calculating the estimated arrival time, calculate the required time when the vehicle is driven at the recommended speed, add the traffic time to the required time, and use the estimated required time as the departure time. The result of addition is obtained as the estimated arrival time, but the arrival speed reflecting the actual traveling speed is estimated by estimating the traveling speed based on the update speed of the current position by the GPS receiver 1012 and correcting the recommended speed according to the estimated speed. The scheduled time can be calculated.
When the reservation is changed to another parking lot 107 in step 613, new location information (latitude and longitude) of the parking lot 107 serving as the destination is transmitted to the portable information terminal 101a (step 605).
On the portable information terminal 101a side, the new position information is reset as a destination (step 606), and guidance to a new parking lot is performed.

以上の処理により、目的地への到着予定時刻の遅早に応じて、目的地周辺の全ての駐車場を対象として最適な駐車場の検索が繰り返し実行され、その検索によって予約変更した結果が携帯情報端末１０１ａまたは１０１ｂに返信され、空車スペースを有する駐車場へと確実に誘導される。この間、搭乗者は駐車場の予約変更のための操作を何ら行う必要がない。 Through the above process, the search for the optimal parking lot is repeatedly performed for all the parking lots around the destination according to the scheduled arrival time at the destination, and the result of the reservation change by the search is carried by the mobile phone. The information is returned to the information terminal 101a or 101b and is surely guided to a parking lot having an empty space. During this time, the passenger does not need to perform any operation for changing the parking reservation.

なお、上記手順では、駐車場を予約した後の目的地への到着予定時刻を駐車場予約サーバ１０４が予測計算しているが、携帯情報端末１０１ａまたは１０１ｂの交通情報取得プログラム２１０５または３１１５により最適経路上の交通情報を取得し、経路探索プログラム２１０１または３１１１が自車位置と目的地までの到着予定時刻を予測計算し、その結果を駐車場予約サーバ１０４に随時送信し、駐車場予約サーバ１０４では受信した到着予定時刻において予約可能な目的地周辺の駐車場を予約、または予約変更するように構成することができる。
すなわち、携帯情報端末１０１ａ、１０１ｂにおいて、ユーザが目的地を設定したならば、経路探索プログラム２１０１、３１１１が探索した目的地までの推奨経路上の交通情報を交通情報取得プログラム２１０５、３１１５により交通情報配信サーバ１０５から取得し、その交通情報に基づき、予約対象が存在する目的地への到着予定時刻を予測演算し、当該到着予定時刻において予約対象を予約するための要求を駐車状予約サーバ１０４へ送信し、予約対象を予約する。この後は、予約した駐車場（目的地）への到着予定時刻を継続して随時算出し、算出した到着予定時刻を駐車状予約サーバ１０４に随時送信する。
一方、駐車場予約サーバ１０４では、携帯情報端末１０１ａ，ｂから随時送信される目的地への到着予定時刻と予約ＤＢ１０３に現在登録されている到着予定時刻との遅早を判定し、その遅早に応じて、目的地周辺の他の駐車場に予約変更し、変更後の予約対象の位置情報を携帯情報端末１０１ａ，１０１ｂに返信し、これを受信した携帯情報端末１０１ａ，１０１ｂでは、予約対象の変更後の位置情報で示される位置を新たな目的地として経路探索プログラム２１０１、３１１１に自動的に再設定し、当該新たな目的地の予約対象までの推奨経路を算出させて案内させるように構成する。
このように構成した場合、駐車場予約サーバ１０４では車両毎に交通情報を取得し、到着予定時刻を計算する負荷が軽くなる。また、携帯情報端末１０１ａ．１０１ｂから駐車場予約サーバ１０４に送信する情報のうち、経路情報を省略することができる。また、運転者は目的地までの到着予定時刻を入力する必要がなくなる。 In the above procedure, the parking space reservation server 104 predicts and calculates the estimated arrival time at the destination after reserving the parking space. However, it is optimal for the traffic information acquisition program 2105 or 3115 of the portable information terminal 101a or 101b. Traffic information on the route is acquired, the route search program 2101 or 3111 predicts and calculates the own vehicle position and estimated arrival time to the destination, and transmits the result to the parking lot reservation server 104 as needed. In this case, it is possible to make a reservation or change a reservation for a parking lot around a destination that can be reserved at the received estimated arrival time.
That is, in the portable information terminals 101a and 101b, if the user sets a destination, traffic information on the recommended route to the destination searched by the route search programs 2101 and 3111 is obtained by the traffic information acquisition programs 2105 and 3115. Based on the traffic information acquired from the distribution server 105, the estimated arrival time to the destination where the reservation object exists is predicted and calculated, and a request for reserving the reservation object at the estimated arrival time is sent to the parking reservation server 104. Send and reserve the reservation target. Thereafter, the estimated arrival time at the reserved parking lot (destination) is continuously calculated as needed, and the calculated estimated arrival time is transmitted to the parking reservation server 104 as needed.
On the other hand, the parking lot reservation server 104 determines the delay between the estimated arrival time at the destination transmitted from the mobile information terminals 101a, 101b as needed and the estimated arrival time currently registered in the reservation DB 103. Accordingly, the reservation information is changed to another parking lot around the destination, and the position information of the reservation object after the change is returned to the portable information terminals 101a and 101b. The position indicated by the changed position information is automatically reset in the route search programs 2101 and 3111 as a new destination, and the recommended route to the reservation target of the new destination is calculated and guided. Constitute.
When configured in this manner, the parking lot reservation server 104 obtains traffic information for each vehicle and reduces the load for calculating the estimated arrival time. In addition, the portable information terminal 101a. Of the information transmitted from 101b to the parking lot reservation server 104, the route information can be omitted. In addition, the driver does not need to input the estimated arrival time to the destination.

また、上記実施の形態では、携帯情報端末１０１ａ，１０１ｂを車両に搭乗した利用者が利用する形態を想定しているが、利用者が歩いて目的地に向かう場合でも適用可能である。
さらに、目的地に到達するまでの間、駐車場予約サーバ１０４と携帯情報端末１０１ａ，１０１ｂとの通信路が接続されたままであった場合、通信費が嵩むことが予想される。これに対しては、目的地と現在地との距離に応じて、間欠的に現在位置を駐車場予約サーバ１０４に送信するように構成すればよい。すなわち、目的地と現在地との距離が大きい区間では例えば１０分間隔で現在位置を駐車場予約サーバ１０４に送信し、現在地と目的地との差が例えば２Ｋｍ未満になったならばリアルタイムで現在位置を駐車場予約サーバ１０４に送信するようにする。
これにより、通信費の増加を抑えることができる。 Moreover, although the said embodiment assumes the form which the user who boarded portable information terminal 101a, 101b uses the vehicle, it is applicable even when a user walks to the destination.
Furthermore, if the communication path between the parking lot reservation server 104 and the portable information terminals 101a and 101b remains connected until the destination is reached, it is expected that communication costs will increase. In response to this, the current position may be intermittently transmitted to the parking lot reservation server 104 according to the distance between the destination and the current location. That is, in a section where the distance between the destination and the current location is large, the current location is transmitted to the parking reservation server 104 at intervals of, for example, 10 minutes, and if the difference between the current location and the destination is less than 2 km, for example, the current location in real time Is transmitted to the parking lot reservation server 104.
Thereby, an increase in communication costs can be suppressed.

図１０および図１１は、駐車場予約サーバ１０４の予約プログラム４０９１が携帯電話機７０１から駐車場の予約要求を受けて予約処理を行い、その後、予約した駐車場まで到達するまでの携帯電話機７０１とのやり取り、および携帯電話機７０１とカーナビゲーション装置７０２とのやり取りを示すシーケンス図である。
携帯電話機７０１を携帯する利用者は、自動車に搭乗して目的地に向かう際に、カーナビゲーション装置７０２の電源を投入する。これにより、経路探索プログラム９０９１、地図表示プログラム９０９２、位置検出プログラム９０９３、交通情報取得プログラム９０９４、携帯電話機インタフェースプログラム９０９５が起動される。
そこで、リモコン装置に実装されたキーパッド９０２を操作し、地図表示プログラム９０９２により目的地が含まれる地域の地図を表示装置９０３に表示させ、その表示された地図上で目的地をリモコン操作によって指定する。例えば目的地として「東京タワー」の位置を指定する。
すると、地図表示プログラム９０９２は指定された目的地の位置情報（経度、緯度情報）を受付け（ステップ１００１）、経路探索プログラム９０９１に渡す。
経路探索プログラム９０９１は、位置検出プログラム９０９３がＧＰＳ受信機９１１による受信電波によって検出している現在位置と利用者が指定した目的地の情報に基づき、現在地から目的地に至る最適経路を道路ネットワーク情報ＤＢ９０５２の道路ネットワーク情報に基づき探索し、その探索結果を表示装置９０３に表示された地図上に合成表示する（ステップ１００２，１００３）。 10 and 11, the reservation program 4091 of the parking lot reservation server 104 receives a reservation request for a parking lot from the mobile phone 701, performs a reservation process, and then reaches the reserved parking lot with the mobile phone 701. FIG. 11 is a sequence diagram showing exchanges and exchanges between the mobile phone 701 and the car navigation device 702.
A user carrying the mobile phone 701 turns on the car navigation device 702 when he / she gets on the car and heads for the destination. As a result, the route search program 9091, the map display program 9092, the position detection program 9093, the traffic information acquisition program 9094, and the mobile phone interface program 9095 are activated.
Therefore, the keypad 902 mounted on the remote control device is operated, the map of the area including the destination is displayed on the display device 903 by the map display program 9092, and the destination is designated on the displayed map by the remote control operation. To do. For example, the position of “Tokyo Tower” is designated as the destination.
Then, the map display program 9092 receives the position information (longitude and latitude information) of the designated destination (step 1001) and passes it to the route search program 9091.
The route search program 9091 determines the optimum route from the current location to the destination based on the road network information based on the current location detected by the position detection program 9093 by the radio wave received by the GPS receiver 911 and the destination information designated by the user. A search is performed based on the road network information in the DB 9052, and the search result is synthesized and displayed on the map displayed on the display device 903 (steps 1002 and 1003).

この状態で、目的地周辺における駐車場を予約する場合、携帯電話機７０１を携帯する利用者は予約プログラム３１１５およびカーナビゲーションインタフェースプログラム３１１６を起動し、予約操作を行う。
すると、予約プログラム３１１５は、カーナビゲーション装置７０２に対して、目的地転送要求をカーナビゲーションインタフェースプログラム３１１５を介して送信する（ステップ１００４）。
目的地転送要求を受信した携帯電話機インタフェースプログラム９０９５は、経路探索プログラム９０９１に設定されている現在の目的地を経路探索プログラム９０９１から取得し、携帯電話機７０１の予約プログラム３１１５に返信する。
目的地の情報を取得した携帯電話機７０１の予約プログラム３１１５は、目的地への到着予定時刻、「当該車両が駐車可能な駐車場タイプの情報」を入力するように利用者に指示する。
そこで、利用者が目的地への到着予定時刻、「当該車両が駐車可能な駐車場タイプの情報」をキーパッド３０２から入力したならば、これを受付けた後、駐車場タイプの情報、目的地までの到着予定時刻と共に、利用者ＩＤを付加した駐車場予約要求情報を駐車場予約サーバ１０４宛に送信する（ステップ１００５）。 In this state, when reserving a parking lot around the destination, the user carrying the mobile phone 701 activates the reservation program 3115 and the car navigation interface program 3116 to perform a reservation operation.
Then, the reservation program 3115 transmits a destination transfer request to the car navigation device 702 via the car navigation interface program 3115 (step 1004).
The mobile phone interface program 9095 that has received the destination transfer request acquires the current destination set in the route search program 9091 from the route search program 9091 and returns it to the reservation program 3115 of the mobile phone 701.
The reservation program 3115 of the mobile phone 701 that acquired the destination information instructs the user to input the estimated arrival time at the destination and “information on the parking lot type that the vehicle can park”.
Therefore, if the user inputs the estimated time of arrival at the destination and “information on the parking type in which the vehicle can be parked” from the keypad 302, after receiving this, the parking type information, destination The parking reservation request information to which the user ID is added is transmitted to the parking reservation server 104 together with the estimated arrival time until (step 1005).

駐車場予約サーバ１０４の予約プログラム４０９１は、携帯電話機７０１から希望の駐車場タイプ、利用者ＩＤ及び目的地までの到着予定時刻等を付加した予約要求情報を受信した場合（ステップ１００６）、到着予定時刻において予約可能な目的地周辺の駐車場１０７を予約ＤＢ１０３より検索し、利用者が希望する駐車場タイプの予約可能な駐車場があれば、その予約処理を行い、予約ＤＢ１０３に予約登録する（ステップ１００７）。そして、予約した駐車場の名称や位置情報を予約完了通知として要求元の携帯電話機７０１に返却する（ステップ１００８）。
なお、駐車場予約サーバ１０４の予約プログラム４０９１は、最適な駐車場１０７が現時点で存在しない場合、駐車場検索を目的地への到着予定時刻の直前まで繰り返す。そして、到着予定時刻までに空車スペースができ、予約が取れた場合、予約完了通知を携帯電話機７０１に返信する。
ここで、予約ＤＢ１０６より駐車場１０７を検索する場合、駐車場タイプ、目的地付近かつ到着予定時刻から所定の駐車時間（例えば２時間など）を確保できる空車スペースが存在する駐車場１０７を検索する。 The reservation program 4091 of the parking lot reservation server 104 receives the reservation request information to which the desired parking lot type, user ID, estimated arrival time to the destination, etc. are received from the mobile phone 701 (step 1006). The parking lot 107 near the destination that can be reserved at the time is searched from the reservation DB 103, and if there is a parking lot that can be reserved of the parking type desired by the user, the reservation processing is performed, and the reservation is registered in the reservation DB 103 ( Step 1007). Then, the name and position information of the reserved parking lot are returned to the requesting mobile phone 701 as a reservation completion notice (step 1008).
It should be noted that the reservation program 4091 of the parking lot reservation server 104 repeats the parking lot search until just before the estimated arrival time at the destination when the optimum parking lot 107 does not exist at the present time. When an empty space is made by the estimated arrival time and a reservation is made, a reservation completion notice is returned to the mobile phone 701.
Here, when searching for the parking lot 107 from the reservation DB 106, the parking lot 107 where there is an empty vehicle space that can secure a predetermined parking time (for example, 2 hours) from the parking lot type, the vicinity of the destination, and the estimated arrival time is searched. .

予約完了通知を受信した携帯電話機７０１の予約プログラム３１１５は、予約した駐車場の名称や位置情報をカーナビゲーション装置７０２に転送する（ステップ１００９）。
カーナビゲーション装置７０２の経路探索プログラム９０９１は、予約した駐車場の位置情報を新たな目的地として再設定し（ステップ１０１０）、その新たな目的地への経路の再探索を実行し、その探索結果の経路を表示装置９０３に表示し、案内誘導を行う（ステップ１０１１）。この場合、予約した駐車場の名称も表示する。
そして、新たな探索結果の経路情報を携帯電話機７０１の予約プログラム３１１５に転送する（ステップ１０１２）。
これに対して、携帯電話機７０１の予約プログラム３１１５は、新たな経路探索結果の情報とＧＰＳ受信機９１１によって検出している自車位置の緯度経度情報とを駐車場予約サーバ１０４に送信する（ステップ１０１３）。
携帯電話機７０１の予約プログラム３１１５は、カーナビゲーション装置７０２の経路探索プログラム９０９１によって経路探索処理が行われる都度、その結果を受信し、駐車場予約サーバ１０４に送信する。 The reservation program 3115 of the mobile phone 701 that has received the reservation completion notification transfers the reserved parking lot name and position information to the car navigation device 702 (step 1009).
The route search program 9091 of the car navigation device 702 resets the reserved parking lot position information as a new destination (step 1010), re-searches the route to the new destination, and the search result Is displayed on the display device 903, and guidance is provided (step 1011). In this case, the name of the reserved parking lot is also displayed.
Then, the route information of the new search result is transferred to the reservation program 3115 of the mobile phone 701 (step 1012).
In response to this, the reservation program 3115 of the mobile phone 701 transmits information on the new route search result and the latitude / longitude information of the vehicle position detected by the GPS receiver 911 to the parking lot reservation server 104 (step). 1013).
The reservation program 3115 of the mobile phone 701 receives the result each time route search processing is performed by the route search program 9091 of the car navigation device 702 and transmits the result to the parking lot reservation server 104.

駐車場予約サーバ１０４は、携帯電話機７０１から現在位置情報と経路情報を受信したならば、現在位置情報が予約ＤＢ１０３に予約登録されている駐車場の位置であるかを判定し（ステップ１０１４）、そうであれば、目的の駐車場に到着したことになるので、当該車両に対する処理を終了する。
しかし、現在位置情報が予約ＤＢ１０３に予約登録されている駐車場の位置でなかった場合には、未だ目的の駐車場に到着していないことになるので、交通情報取得プログラム９０９４により携帯電話機７０１から受信した経路情報をもとに交通情報配信サーバ１０５から該当経路上の渋滞等の交通情報を取得し（ステップ１０１５）、予約した駐車場１０７までの到着予定時刻を予測計算する（ステップ１０１６）。
駐車場予約サーバ１０４は、ステップ１０１６で算出された到着予定時刻と、予約ＤＢ１０３に現在登録されている到着予定時刻とを比較し、到着予定時刻が遅れるのか、早まるのかを判定する（ステップ１０１７）。
そして、到着予定時刻の遅早に応じて、駐車場予約サーバ１０４が管理している目的地周辺の駐車場における空きスペースを検索し、最適な駐車場に予約を変更する。具体的には、予約ＤＢ１０３に現在登録されている駐車場を新たな駐車場に書き換え、かつ当該駐車場への到着予定時刻を登録する（ステップ１０１８）。
この場合、同じ駐車場１０７の別の駐車スペースになる場合もあるが、駐車場予約サーバ１０４に登録されている別の駐車場１０７になる場合もある。 When receiving the current position information and route information from the mobile phone 701, the parking lot reservation server 104 determines whether the current position information is a parking lot position that is reserved and registered in the reservation DB 103 (step 1014). If so, it means that the vehicle has arrived at the target parking lot, and the processing for the vehicle is terminated.
However, if the current location information is not the parking location that is reserved and registered in the reservation DB 103, it means that the destination parking lot has not yet been reached. Based on the received route information, traffic information such as traffic jam on the route is acquired from the traffic information distribution server 105 (step 1015), and the estimated arrival time to the reserved parking lot 107 is predicted and calculated (step 1016).
The parking lot reservation server 104 compares the estimated arrival time calculated in step 1016 with the estimated arrival time currently registered in the reservation DB 103, and determines whether the estimated arrival time is delayed or advanced (step 1017). .
And according to the arrival time of the estimated arrival time, an empty space in the parking lot around the destination managed by the parking lot reservation server 104 is searched, and the reservation is changed to the optimum parking lot. Specifically, the parking lot currently registered in the reservation DB 103 is rewritten to a new parking lot, and the estimated arrival time at the parking lot is registered (step 1018).
In this case, it may be another parking space of the same parking lot 107, but may be another parking lot 107 registered in the parking lot reservation server 104.

なお、到着予定時刻を予測計算する場合、推奨速度で車両を走行させた場合の所要時間を算出し、その所要時間に渋滞時間を加算した結果を予測所要時間とし、出発時刻に予測所要時間を加算した結果を到着予定時刻として求めるが、車速センサ９１３が検出している走行速度を駐車場予約サーバ１０４に送信し、実際の走行速度に応じて推奨速度を補正することにより、実際の走行速度を反映した到着予定時刻を算出することができる。
ステップ１０１８で別の駐車場１０７に予約変更した場合、携帯電話機７０１に対して目的地となる駐車場１０７の新たな位置情報（緯度経度）を送信する（ステップ１００８）。
携帯電話機７０１は、その新たな位置情報をカーナビゲーション装置７０２に転送し、目的地を再設定させ（ステップ１０１０）、新たな駐車場への案内誘導を行う。 When calculating the estimated arrival time, calculate the required time when the vehicle is driven at the recommended speed, add the traffic time to the required time, and use the estimated required time as the departure time. The result of addition is obtained as the estimated arrival time, but the actual traveling speed is obtained by transmitting the traveling speed detected by the vehicle speed sensor 913 to the parking lot reservation server 104 and correcting the recommended speed according to the actual traveling speed. It is possible to calculate the estimated arrival time reflecting the above.
When the reservation is changed to another parking lot 107 in step 1018, new location information (latitude and longitude) of the parking lot 107 serving as the destination is transmitted to the mobile phone 701 (step 1008).
The cellular phone 701 transfers the new position information to the car navigation device 702, resets the destination (step 1010), and guides the new parking lot.

以上の処理により、目的地への到着予定時刻の遅早に応じて、目的地周辺の全ての駐車場を対象として最適な駐車場の検索が繰り返し実行され、その検索によって予約変更した結果がカーナビゲーションッ装置７０２に返信され、空車スペースを有する駐車場へと確実に誘導される。この間、搭乗者は駐車場の予約変更のための操作を何ら行う必要がない。 With the above processing, the search for the optimal parking lot is repeatedly performed for all the parking lots around the destination according to the expected arrival time at the destination, and the result of the reservation change by the search is the result of the reservation change. It is returned to the navigation device 702 and is surely guided to a parking lot having an empty space. During this time, the passenger does not need to perform any operation for changing the parking reservation.

なお、上記手順においても、駐車場を予約した後の目的地への到着予定時刻を駐車場予約サーバ１０４が予測計算しているが、カーナビゲーション装置７０２の交通情報取得プログラム９０９４により最適経路上の交通情報を取得し、その交通情報を携帯電話機７０１の予約プログラム３１１５に転送し、予約プログラム３１１５が自車位置と目的地までの到着予定時刻を予測計算し、その結果を駐車場予約サーバ１０４に随時送信し、駐車場予約サーバ１０４では受信した到着予定時刻において予約可能な目的地周辺の駐車場を予約、または予約変更するように構成することができる。
すなわち、カーナビゲーション装置７０２において、ユーザが目的地を設定したならば、経路探索プログラム９０９１が探索した目的地までの推奨経路上の交通情報を交通情報取得プログラム９０９４により交通情報配信サーバ１０５から取得し、その交通情報を予約プログラム３１１５に転送し、予約プログラム３１１５において、予約対象が存在する目的地への到着予定時刻を予測演算し、当該到着予定時刻において予約対象を予約するための要求を駐車状予約サーバ１０４へ送信し、予約対象を予約する。この後は、予約した駐車場（目的地）への到着予定時刻を継続して随時算出し、算出した到着予定時刻を駐車状予約サーバ１０４に随時送信する。
一方、駐車場予約サーバ１０４では、携帯電話機７０１から随時送信される目的地への到着予定時刻と予約ＤＢ１０３に現在登録されている到着予定時刻との遅早を判定し、その遅早に応じて、目的地周辺の他の駐車場に予約変更し、変更後の予約対象の位置情報を携帯電話機７０１に返信し、これを受信した携帯電話機７０１は変更後の位置情報をカーナビゲーション装置７０２に転送し、カーナビゲーション装置７０２において予約対象の変更後の位置情報で示される位置を新たな目的地として経路探索プログラム９０９１に自動的に再設定し、当該新たな目的地の予約対象までの推奨経路を算出させて案内させるように構成する。
以上のように、携帯情報端末を携帯電話機と既存のカーナビゲーション装置で構成した場合、カーナビゲーション装置の既存の機能を活用することができるため、図１の携帯電話機１０１４に比べて携帯電話機７０１の構成を簡素なものにすることができる。 Even in the above procedure, the parking lot reservation server 104 predicts and calculates the estimated arrival time at the destination after reserving the parking lot. However, the traffic information acquisition program 9094 of the car navigation device 702 is on the optimum route. The traffic information is acquired, and the traffic information is transferred to the reservation program 3115 of the mobile phone 701. The reservation program 3115 predicts and calculates the own vehicle position and the estimated arrival time to the destination, and the result is sent to the parking lot reservation server 104. The parking lot reservation server 104 can transmit at any time, and can be configured to reserve or change the reservation around the destination parking lot that can be reserved at the estimated arrival time.
That is, in the car navigation device 702, when the user sets a destination, the traffic information on the recommended route to the destination searched by the route search program 9091 is acquired from the traffic information distribution server 105 by the traffic information acquisition program 9094. Then, the traffic information is transferred to the reservation program 3115, and the reservation program 3115 predicts the estimated arrival time at the destination where the reservation object exists, and issues a request for reserving the reservation object at the estimated arrival time as a parking letter. It transmits to the reservation server 104 and reserves a reservation object. Thereafter, the estimated arrival time at the reserved parking lot (destination) is continuously calculated as needed, and the calculated estimated arrival time is transmitted to the parking reservation server 104 as needed.
On the other hand, the parking reservation server 104 determines whether the scheduled arrival time to the destination transmitted from the mobile phone 701 as needed and the estimated arrival time currently registered in the reservation DB 103 are early, and according to the delay. The reservation is changed to another parking lot around the destination, and the position information of the reservation object after the change is returned to the mobile phone 701, and the mobile phone 701 that receives this changes the changed position information to the car navigation device 702. In the car navigation device 702, the position indicated by the position information after the change of the reservation target is automatically reset in the route search program 9091 as a new destination, and the recommended route to the reservation target of the new destination is set. It is configured to calculate and guide.
As described above, when the portable information terminal is configured by a mobile phone and an existing car navigation device, the existing functions of the car navigation device can be used. The configuration can be simplified.
