  Next, the operation of the first embodiment will be described with reference to the flowchart of FIG. 2 and FIG. First, when an e-mail arrives at the e-mail address of the mobile phone 124, it is determined that the external information has been received by informing the driver that the e-mail has arrived by voice using the speaker 122 (incoming e-mail). The system waits for an instruction for the next action from the person. The driver instructs the next action by a command command by voice from the steering wheel button 126 or the microphone 123. The next action is to read out the mail (S201 to S211), reply with a fixed sentence (S202 to S213), direct to a place where the mail can be safely created (S202 to S203), do nothing in particular (S202 to S213) ) Etc. When reading a mail (S211), there are a name, contact information (telephone number, etc.) that can identify the other party in the read content, that is, if the other party can be identified based on the content read out in this way (in S212) In the case of Y), the steering wheel button 126 or the command instruction moves to the next action (S202 to S203) for guiding to a place where the mail can be safely created, and the guidance process to the mail creating place is entered. Stop information can be selected. On the other hand, if the other party cannot be specified, nothing is done (in the case of N in S212), the process returns to the state immediately before the incoming mail (S214) and the process is terminated. Also, in replying to a fixed phrase, a preset sentence or an automatically generated mail including the current position and destination information is returned (S213), and the process returns to the state before the incoming mail (S214). Exit. After the process is completed, if the destination of the route guidance is set in the vehicle route guidance device 100 before receiving the mail, and guidance is in progress, the guidance is continued.

  Next, a case where the vehicle route guidance device 100 is set so as to guide to a place where a mail can be safely created will be described.

  Stop information in the vicinity of the current position is divided into facility genres, priorities are set in the guidance list presented to the driver, and stored in the genre list database 109. Here, examples of genres that divide the facilities include convenience stores, supermarkets, bookstores, public facilities (civic center, gymnasium, library), and other facilities that can be parked for free, places on the street (evacuation areas, roadside belts), etc. Is given. An example of the genre list database 109 is shown in Table 1. The driver can set priorities for these genres.

また、これらのジャンルに対応するそれぞれの施設の付随情報として、施設名・店名、駐車スペースの規模、定休日、休館日、営業時間等をデータベース化し、運転者に示す誘導リストの中での優先順位を設定し、ジャンルリストと関連付け、施設の位置データとともに施設付随データベース１１０に保持する。付随情報について表２に示す。

In addition, as incidental information for each facility corresponding to these genres, the facility name / store name, parking space size, regular holidays, closed days, business hours, etc. are compiled into a database and given priority in the guidance list shown to the driver. The ranking is set, associated with the genre list, and stored in the facility-accompanying database 110 together with the location data of the facility. The accompanying information is shown in Table 2.

このように予め蓄積している施設データの中からジャンルの優先順位別に安全にメールを作成できる施設を選び、現在地からの距離、方向、目的地（進行方向）からのずれ、車速から求められる停止可能距離、進行方向に対し道の左側にあるか、右側にあるか等の状況情報と、施設の付随情報としてデータベース化した駐車スペースの規模、定休日、休館日、営業時間等を考慮し、誘導リスト中の施設に優先順位を付け、運転手にモニタ１２７を用いて誘導リストを提示する（Ｓ２０３）。運転手は提示された誘導リスト中の１つの停車情報をステアリングホイールボタン１２６、あるいはコマンド指示により、経由地として決定（Ｓ２０４）し、決定した経由地に向け、走行誘導を開始する（Ｓ２０５）。または、運転者が所定の時間の間にステアリングホイールボタン１２６、あるいはコマンド指示により、誘導リスト中の１つの停車情報を決定しなければ、優先順位の最も高い順位の停車情報を経由地として決定できる。

In this way, you can select a facility that can be used to create e-mails safely according to the priority order of the genre from the facility data that has been stored in advance, and the distance required from the current location, direction, deviation from the destination (traveling direction), and the stop required from the vehicle speed. Considering the possible distance, situation information such as whether it is on the left or right side of the road with respect to the direction of travel, the size of the parking space databased as incidental information of the facility, regular holidays, closed days, business hours, etc. Priorities are assigned to the facilities in the guidance list, and the guidance list is presented to the driver using the monitor 127 (S203). The driver determines one stop information in the presented guidance list as a waypoint by the steering wheel button 126 or command instruction (S204), and starts driving guidance toward the decided waypoint (S205). Alternatively, if the driver does not determine one stop information in the guidance list by the steering wheel button 126 or a command instruction during a predetermined time, the stop information with the highest priority order can be determined as a waypoint. .

  In addition, when the guidance is canceled after starting the mail creation location, it returns to the state before the incoming mail, for example, when the destination set before the incoming mail is set, the incoming mail is received when the guidance is stopped. The destination already set before is set as the current destination, the route is searched, and the guidance is continued. The commands that can be selected while directing to the mail composition location are as follows: canceling the guidance described above, changing to another mail creation location candidate, re-reading the email, replying with a fixed text or preset text These settings can be easily selected by the steering wheel button 126 or a command instruction.

  When guidance to the facility selected by the driver is completed, the driver gives the steering wheel button 126 or command indication that guidance is complete, or recognizes that the vehicle route guidance device 100 has arrived around the waypoint Thus, the guidance to the facility is terminated (S206), and a transition to the mail reply mode is awaited. In this state, when the parking brake is pulled (the parking brake signal 128 outputs a signal) (S208), the mail reply message creation mode (S209) is automatically entered. In addition, when there is no parking space in the arrived facility or the vehicle is temporarily closed, the steering wheel button 126 or the command instruction can be easily made so as to detect the stop information again.

  After creating the mail and sending the mail (S210), the process returns to the state before the incoming mail (S214), and the process is terminated. That is, if the destination is set in the vehicle route guidance device 100 before the mail arrives, the vehicle route guidance device 100 creates a reply message of the mail and automatically sends the mail before the mail arrival when the transmission is completed. A route search is performed for the destination and the driving guidance is resumed. If the destination is not set before the mail arrives, the vehicle route guidance device 100 creates a mail reply and returns to the state before the mail arrives when the transmission is completed.

  In this way, in order to create a reply to the e-mail, it is necessary to stop at a safe place and create an e-mail, but in order to find a safe place, the driver looks for a safe place other than driving Avoid situations where attention is paid to other than driving.
