Reference numeral 9 denotes an operation unit that is used not only for basic operation of the apparatus but also when selecting an e-mail address or transmission time setting.

  The main control device 1 implements the following means while using a storage device such as a memory according to the control program.

[2. Effect)
[2-1. (Basic effects)
A basic processing procedure in the present embodiment configured as described above is shown in the flowchart of FIG. That is, when the automatic mail transmission mode is started (step S1), first, the address designating unit 12 displays the mail address list and accepts the designation of the mail address of the transmission partner by inputting a character string or the like (step S2). The timing setting unit 14 also accepts selection of an interval time to be transmitted (step S3).

  Thereafter, the vehicle position detection means 16 sequentially detects the vehicle position based on GPS positioning data obtained by the position detection unit 2, an output from an angular velocity sensor such as a gyro, a vehicle speed signal, and the like (step S4). The vehicle position obtained here is represented by vehicle position data such as a road link that is running in addition to the position coordinates on the earth. Based on the vehicle position data, the CPU 1 stores the database in the main storage device 3. The current position map is drawn by the image drawing control unit 6 and displayed on the display unit 7.

  Then, the timing determining means 18 determines that it is the timing of mail transmission every time the designated time interval elapses (step S5), and when the timing determining means 18 determines that it is the timing of mail transmission, the address extracting means 20 Based on the address data stored (stored) in the storage device 3, the current location address corresponding to the current position information detected by the vehicle position detection means 16 is extracted.

  After that, the mail transmission means 22 creates an electronic mail (transmission mail) in which the current location address is inserted in the standard text (step S6), and transmits the created mail to the designated mail address (step S7). Thereafter, the process returns to vehicle position detection (step S4) (step S8) except when the automatic mail transmission mode is terminated (step S9).

In this way, the address of the vehicle position to be detected sequentially is automatically transmitted to the designated partner by e-mail at a predetermined timing while safely driving without setting operation such as destination, route and transmission point. And the other party can know the current location one after another.
Hereinafter, more specific processing contents and other ideas will be described.

[2-2. (Timing judgment)
First, distance, time, and a combination thereof can be considered as a reference for the timing determination means 18 to determine the timing of mail transmission. Of these, in the case of a distance, the timing determination means 18 determines that it is the timing of mail transmission every time it travels a predetermined distance (for example, 30 km, 25% of the stroke). In this way, by sending e-mails at a predetermined distance instead of time, the number of e-mails is not increased unnecessarily even when the speed is low, and the other party can experience the distance from the e-mail arrival timing.

  Further, in the case of time, the timing determination means 18 determines that it is a mail transmission timing every time a predetermined time (for example, 30 minutes, 25% of the expected required time at the time of departure) elapses. In this way, by sending e-mails not at a distance but at a predetermined time, e-mails can be relieved continuously even when the speed is low.

  Particularly desirable is a combination of distance and time. In this case, the timing determination unit 18 travels a predetermined distance from the previously determined mail transmission timing, or a predetermined time elapses, whichever comes first, at which time the mail transmission timing is established. Judge that there is. In this way, by using the distance and time together in judging the timing of mail transmission, if the running is smooth, the mail arrives one after another and you can see the progress, and even if there is a traffic jam, the mail arrives at a fixed time interval It becomes possible to utilize the advantage of the distance system and the advantage of the time system in combination.

  Further, as described above, for the predetermined distance and the predetermined time that are the reference of the timing of mail transmission, the timing setting unit 14 receives the designation from the user in units of kilometers or minutes. As described above, by specifying the distance and time that are the basis of the mail transmission timing, it is possible to use the user according to the preference and circumstances of each user and each partner.

[2-3. (Transmission of maps and traffic information)
It is also desirable to send not only the current location address but also other information. One of them is to send a map. The large-capacity storage device 3 is provided with map data storage means 24 for storing map data, and the vehicle position detected by the vehicle position detection means 16 by the map image creation means 26. Is created based on the map data stored in the map data storage means 24. In addition, the mail transmission means 22 includes the surrounding map image created by the map image creation means 26 in the e-mail. In order to include an image in an e-mail, in addition to an attached file, an image may be uploaded to a server, and an access URL may be included in the e-mail. The same applies to other images.

  Thus, by including the map image around the vehicle position in the mail, the other party can intuitively grasp the actual location and the surrounding geography that are difficult to understand only by the address.

  Traffic information can also be sent. That is, traffic information such as VICS by FM multiplex broadcasting or beacon is acquired by the traffic information acquisition means 28, and the traffic information acquired by the traffic information acquisition means 28 is sent to the e-mail by a character string or attached by the mail transmission means 22. Include in the form of an image file.

  In this way, traffic information such as accidents, construction, and traffic regulations that can be obtained with VICS can be included in the e-mail so that the other party can understand the background of the current traffic situation and guess the future prospects. become.

  In particular, it is desirable that the traffic information is traffic jam information (for example, traffic jam location, section, degree, estimated transit time, etc.). Similar to the car navigation map display, it is easy to understand if the traffic congestion section is displayed in an orange or red band depending on the degree in the surrounding image as described above. In this way, by including traffic jam information in the traffic information in the mail, it becomes possible for the other party to determine in detail the background of the current delay and how much the arrival time is delayed.

[2-4. (Transmission of vehicle speed)
Moreover, the vehicle speed of the vehicle itself can be sent. For example, the average vehicle speed calculation means 28 calculates the average vehicle speed in a predetermined time (for example, 30 minutes, 1 hour, etc.) before transmission based on the vehicle speed, and the mail transmission means 22 calculates the average vehicle speed calculation means 28. Include the average vehicle speed in the email. Thus, by transmitting the average vehicle speed as well, the opponent can more accurately estimate the vehicle status and arrival time.

  As another aspect, the graph creation means 30 creates an image of a vehicle speed transition graph for a predetermined time before transmission based on the vehicle speed, and the mail transmission means 22 uses the vehicle speed created by the graph creation means 30. Include transition graph images in emails. In this way, by sending the vehicle speed transition graph as well, the opponent can see more changes in the situation along the flow of time, such as whether the vehicle speed is stable, whether the traffic congestion is mitigating or becoming severe. It becomes possible to grasp concretely.

[2-5. (Transmission of facial expressions)
You can also send facial expressions. In this case, the facial expression storage means 32 stores a plurality of types of facial expression information, and the facial expression selection means 34 accepts selections from multiple types of facial expressions stored in the facial expression storage means 32. Information on the facial expression selected by the facial expression selection means 34 is read from the facial expression storage means 32 by the mail transmission means 22 and included in the electronic mail. In this way, it is possible to select a facial expression such as happy, tired, thank you, sorry, etc. and easily attach it to an e-mail.

  Specifically, as the facial expression information in this case, it is conceivable to first use a computer graphic image. In this way, if the facial expression is conveyed by a CG image, an added value that enables more lively communication is obtained.

  In addition, as the facial expression information, a so-called emoticon that is a combination of a plurality of characters may be used. In this way, if facial expressions are conveyed by emoticons, it is possible to convey feelings with a small amount of data regardless of the system environment on the receiving side, such as whether an attached image can be displayed.

  It is also desirable to make the interface for selecting facial expressions easy. For example, each time the timing determination unit 18 determines that it is the timing of mail transmission, the facial expression selection unit 34 displays a facial expression candidate for selection during a predetermined standby time (for example, 5 seconds, 10 seconds, etc.). I wait. In this way, the facial expression candidates are displayed on the screen at every e-mail transmission timing and waiting for selection, thereby facilitating the attachment operation and forgetting the attachment. If there is no selection operation during the standby time, the facial expression information may not be attached, the standard facial expression may be attached, or the previously used facial expression may be attached.

[2-6. Confirm that you have read the email)
A person in the car can confirm that the other party has read the email. In this case, the mail transmission means 22 includes the URL or the reply destination e-mail address as the confirmation address in the e-mail information. Specifically, a confirmation URL is entered in the body of the email and a description requesting an operation is entered, or the user himself / herself and a confirmation-specific email address are specified in Reply-To, and a text requesting a reply is included. Then, based on the access or reply to the confirmation address, the confirmation means 36 confirms whether the other party has read by confirming with the web server or the mail server when accessing the outside for the next mail transmission, for example. And inform the user.

  In this way, by checking whether the other party has read the e-mail and notifying the user, it is possible for the user in the car to easily check whether the other party is properly communicating, including the possibility of technical troubles, and continue safe driving with peace of mind. be able to.
