次に動作について説明する。
図２は、実施の形態１に係るナビゲーションシステムの動作を示すフローチャートであり、車載ナビゲーション装置１を搭載し、携帯端末２が持ち込まれた車両が駐車した際の動作を示している。
まず、駐車判定部１０は、車載ナビゲーション装置１が起動している間、自車両の車両状態情報を常にモニタして、自車両が駐車したか否かを判定する（ステップＳＴ１）。
自車両が駐車していなければ（ステップＳＴ１；ＮＯ）、ステップＳＴ１の処理を繰り返す。 Next, the operation will be described.
FIG. 2 is a flowchart showing the operation of the navigation system according to the first embodiment, and shows the operation when the vehicle on which the in-vehicle navigation device 1 is mounted and the portable terminal 2 is brought in is parked.
First, the parking determination unit 10 always monitors the vehicle state information of the host vehicle while the in-vehicle navigation device 1 is activated, and determines whether or not the host vehicle is parked (step ST1).
If the host vehicle is not parked (step ST1; NO), the process of step ST1 is repeated.

駐車判定部１０は、車両状態情報から車速が０かつパーキングブレーキが使用されていると判断され、自車両が駐車したと判定した場合（ステップＳＴ１；ＹＥＳ）、位置情報取得部１１に対して自車両の現在位置（駐車位置）を取得するよう指示する。
位置情報取得部１１は、駐車判定部１０からの指示に従って、自車両の駐車位置を取得する（ステップＳＴ２）。位置情報取得部１１により取得された位置情報は、近距離無線通信部１２へ出力される。 When it is determined from the vehicle state information that the vehicle speed is 0 and the parking brake is used, and the parking determination unit 10 determines that the host vehicle is parked (step ST1; YES), the parking determination unit 10 automatically Instructs the vehicle to acquire the current position (parking position).
The position information acquisition part 11 acquires the parking position of the own vehicle according to the instruction | indication from the parking determination part 10 (step ST2). The position information acquired by the position information acquisition unit 11 is output to the short-range wireless communication unit 12.

近距離無線通信部１２は、位置情報取得部１１から自車の駐車位置情報を入力すると、駐車判定部１０からの指示に従って、携帯端末２の近距離無線通信部２０と近距離無線通信を確立し、上記駐車位置情報を送信する（ステップＳＴ３）。
携帯端末２において、近距離無線通信部２０が、車載ナビゲーション装置１から自車両の駐車位置情報を受信する（ステップＳＴ４）。近距離無線通信部２０によって車載ナビゲーション装置１から受信された車両の駐車位置情報は駐車位置記憶部２１に記憶される（ステップＳＴ５）。

As an example, a user who gets off the vehicle carries the mobile terminal 2 and moves to the “Δ × building” shown in FIG. 4.
When the user completes the business in “Δ × building” and performs the guidance start operation using the input unit 25, the parking position guide unit 23 reads the parking position information of the own vehicle from the parking position storage unit 21 (step ST1a ).

次に、駐車位置案内部２３は、地図情報取得部２４に対して自車の駐車位置を含む周辺の地図情報を要求する。地図情報取得部２４は、駐車位置案内部２３からの要求に応じて自車の駐車位置を含む周辺の地図情報を取得し、駐車位置案内部２３へ応答する。
駐車位置案内部２３は、地図情報取得部２４から入力した地図情報を用いて、自車両の駐車位置を含む周辺地図を作成する（ステップＳＴ２ａ）。 Next, the parking position guide part 23 requests | requires the map information of the periphery containing the parking position of the own vehicle with respect to the map information acquisition part 24. FIG. The map information acquisition unit 24 acquires peripheral map information including the parking position of the host vehicle in response to a request from the parking position guide unit 23, and responds to the parking position guide unit 23.
The parking position guide unit 23 uses the map information input from the map information acquisition unit 24 to create a surrounding map including the parking position of the host vehicle (step ST2a).

続いて、駐車位置案内部２３は、ステップＳＴ２ａで作成した周辺地図を出力部２６に表示させ、現在位置から駐車位置までのルート案内を行う（ステップＳＴ３ａ）。
ここでは、図４のような駐車位置案内画面２６ａが出力部２６の表示部に表示され、ユーザは、この駐車位置案内画面２６ａに従って自車の駐車位置である“△×駐車場”まで戻ることができる。 Subsequently, the parking position guide unit 23 displays the surrounding map created in step ST2a on the output unit 26, and performs route guidance from the current position to the parking position (step ST3a).
Here, a parking position guidance screen 26a as shown in FIG. 4 is displayed on the display unit of the output unit 26, and the user returns to “△ × parking lot” which is the parking position of the vehicle according to the parking position guidance screen 26a. Can do.
