[0029]
The in-vehicle electronic mail communication device 1 includes a control unit (hereinafter referred to as “CPU”) 2, a memory 3, a recording unit 4, a communication unit 5, an operation unit 6, a time measuring unit 7, a video processing unit 8, a display unit 9, a GPS A signal receiving unit 10 and an internal bus 11 are provided. Data exchange between each part in the in-vehicle electronic mail communication apparatus 1 is performed via the internal bus 11. When the power source (not shown) of the in-vehicle electronic mail communication apparatus 1 is turned off, the data recorded in the memory 3 disappears, but the data recorded in the recording unit 4 remains as it is, and the next in-vehicle electronic The mail communication apparatus 1 can be used when the power is turned on. A mobile phone 20 is connected to the communication unit 5 of the in-vehicle electronic mail communication apparatus 1. The operation unit 6 receives an instruction from the user to the in-vehicle electronic mail communication apparatus 1.
[0030]
The base station 30 is a facility for providing a wireless communication service to the mobile phone 20. The portable mail server 40 is a mail server that provides the cellular phone 20 with a mail exchange dedicated to the cellular phone, and the PC mail server 50 represents a mail server for a general computer.
[0031]
FIG. 2 is a flowchart showing processing when the in-vehicle electronic mail communication apparatus 1 receives an electronic mail. The flowchart shown in FIG. 2 mainly shows processing performed by the CPU 2. The following description relates to processing performed by the CPU 2 unless otherwise specified, and the description of mail represents an electronic mail. In the following description, various images may be displayed on the display unit 9. This is because the CPU 2 reads out the corresponding image data recorded in advance in the recording unit 4 and transmits it to the video processing unit 8. The video processing unit 8 converts the signal into a predetermined analog signal and transmits it to the display unit 9.
[0032]
First, it is determined whether or not the mobile phone 20 is connected to the communication unit 5 (step S1). For connection between the mobile phone 20 and the communication unit 5, a cable, infrared rays, weak radio waves, or the like can be used.
[0033]
If it is determined that the mobile phone 20 is connected, the mobile phone 20 is requested to transmit information related to the mobile phone 20, and the telephone number and the mail address are acquired and recorded in the recording unit 4 (step S2). ). For obtaining information from the mobile phone 20, for example, the CPU 2 transmits a predetermined command (for example, a command obtained by extending an AT command) to the mobile phone 20, and the mobile phone 20 transmits corresponding information to the command. This can be done.
[0034]
Next, it is determined whether or not there is a setting instruction regarding mail reception (step S3). The setting relating to mail reception is performed by operating the operation unit 6 by the user by displaying an image asking whether or not to perform the setting on the display unit 9. If it is determined that a setting instruction related to mail reception has been received, a setting image is displayed on the display unit 9 to accept the setting (step S4). If it is determined that the setting has been canceled, the process proceeds to step S5.
[0035]
FIG. 3 is a diagram illustrating an example of a setting image related to mail reception. In response to the operation of the operation unit 6 by the user, the CPU 2 enables / disables the privacy protection function, the mobile phone number that permits transmission of the received mail, the unconditional forwarding destination and the unconditional forwarding source mail address, and the transmission target mail address. Register or change. For privacy protection and unconditional transfer, a flag for distinguishing validity / invalidity is provided. For example, “1” is set when enabled, and “0” is set when disabled. As for the unconditional transfer setting, if there is any change in the valid / invalid setting and the mail address, “1” is set in the flag indicating the change. These setting data and flags are recorded in the recording unit 4, and the previous setting state is displayed. Details of the privacy protection function and the transmission of received mail will be described later.
[0036]
Next, a flag indicating the change of the unconditional transfer destination is read from the recording unit 4, and it is determined whether or not the value is “1” (step S5). When the read value is “1” and the flag for distinguishing the validity / invalidity of unconditional transfer is “1”, that is, the flag is valid, the unconditional transfer destination mail address recorded in step S4 is read from the recording unit 4, The information is transmitted to the PC mail server 50 set in advance, and “0” is set in a flag indicating change of unconditional transfer (step S6). If the flag indicating whether or not the unconditional forwarding destination e-mail address has been changed is “1” and the flag for distinguishing the validity / invalidity of the unconditional forwarding is “0”, that is, if the flag is invalid, the preset PC mail An empty unconditional forwarding destination e-mail address is transmitted to the server 50, and “0” is set in a flag indicating change of unconditional forwarding (step S6).
[0037]
For example, when the unconditional transfer is set to be effective and the mail address is changed as shown in FIG. 3, the in-vehicle e-mail communication device 1 reads “forwarding destination: a123@keitai.ne.jp” and The mail data including the text data of “forwarding source: b456@provider.ne.jp” in the mail body and the mail subject “change forwarding destination” is transmitted to the PC mail server 50. If the received mail subject is “change forwarding destination”, the PC mail server 50 searches the mail body using “forwarding destination” and “forwarding source” as search keys, and sends the email address a123@keitai.ne.jp. And b456@provider.ne.jp. The PC mail server 50 newly changes the forwarding mail address already recorded in the database corresponding to the forwarding mail address b456@provider.ne.jp to a123@keitai.ne.jp. As a result, the mail addressed to b456@provider.ne.jp is automatically transferred to the forwarding mail address a123@keitai.ne.jp by the PC mail server 50. For example, if a123@keitai.ne.jp set as the unconditional forwarding destination e-mail address is the e-mail address of the mobile phone 20 connected to the in-vehicle e-mail communication device 1, b456@provider.ne.jp All the mails addressed can be received by the in-vehicle electronic mail communication apparatus 1.
[0038]
If the unconditional transfer is changed to invalid, the in-vehicle e-mail communication device 1 includes the text data of “forwarding destination:” and “forwarding source: b456@provider.ne.jp” in the mail body, An email with the subject line “change destination” is transmitted to the PC mail server 50. The PC mail server 50 searches the mail text in the same manner as described above, and acquires an empty mail address as the transfer destination and b456@provider.ne.jp as the transfer source. The PC mail server 50 deletes the forwarding mail address already recorded in the database corresponding to the forwarding mail address b456@provider.ne.jp. As a result, the transfer can be canceled.
[0039]
After the above processing, the in-vehicle electronic mail communication apparatus 1 waits for an instruction to receive a mail (step S7). When the mobile mail server 40 receives a mail addressed to the mobile phone 20, the mobile mail server 40 notifies the mobile phone 20 that a new mail has been received. Upon receiving this notification, the mobile phone 20 receives an incoming call by ringing sound or vibration. Inform. In response to this notification, the mail reception instruction means that the user operates the operation unit 6 to instruct reception of mail. If the CPU 2 determines that there is no mail reception instruction, the process proceeds to step S16. If it is determined that there is a mail reception instruction, the communication function of the mobile phone 20 is controlled and the mobile phone 20 is used as a modem to receive mail. And recording (step S8).
[0040]
The mail is received as packet data having a predetermined header, and the in-vehicle electronic mail communication device 1 combines the packets in a predetermined order based on the header information, reconfigures it as a mail file, Record in the temporary recording location.
[0041]
Next, it is determined whether or not the received mail is a mail to be transmitted (step S9). For example, the header information of the received mail is searched by using “Form” as a search key, the sender's mail address is acquired, and the acquired mail address is compared with the transmission target mail address set in step S4. be able to. If it is determined that these two mail addresses match, the process proceeds to step S12 for processing mail transmission to the connected mobile phone 20, and if it does not match, the validity / invalidity of the privacy protection function is determined. The process proceeds to step S10.
[0042]
If it is determined in step S10 that the privacy protection function is enabled, it is determined whether or not the telephone number of the connected mobile phone 20 matches the telephone number for which transmission permission is set in step S4. (Step S11). If it is determined that the setting is invalid, the process proceeds to step S15.
[0043]
If it is determined in step S11 that the telephone number of the connected mobile phone 20 acquired in step S2 matches the telephone number for which transmission permission is set in step S4, the temporary recording location of the recording unit 4 is used in step S8. The received mail is acquired and transmitted to the mobile phone 20 (step S12). If it is determined that they do not match, the process proceeds to step S15.
[0044]
Normally, an electronic mail is communicated as one file (a file in which an attached file is encoded and integrated with a mail body) even when the file is attached. Therefore, the mail received in step S8 may be recorded as one file even if there is an attached file, and transmitted to the mobile phone 20 with a predetermined communication specification as one file. Also, if there is an attached file in the mail received in step S8, it is possible to decode the attached file, add information indicating correspondence with the mail text, and record the mail text and the attached file as each file. In this case, the plurality of files are transmitted to the mobile phone 20.
[0045]
Next, it is determined whether or not the transmission of the received mail to the mobile phone 20 has been completed normally (step S13). If it is determined that the transmission has been completed normally, the mail received at step S8 is deleted from the temporary recording location. (Step S14), the process proceeds to Step S16.
[0046]
If the privacy protection function is disabled or if it is determined that the connected mobile phone number does not match the phone number permitted for transmission in step S4 even if it is enabled, it is received in step S8. The recorded mail is read from the temporary recording location of the recording unit 4 and recorded in the regular recording location, and the reception time, transmission time, transmission source email address, subject, etc. of the email are recorded in the recording unit 4 as reception history, The process proceeds to step S16 (step S15). The reception time is acquired from the time measuring unit 7, and the transmission time and the transmission source mail address are acquired from the mail header.
Finally, it is determined whether or not there is an end instruction (step S16), and the processes of steps S3 to S15 are repeated until it is determined that there is an end instruction.
[0047]
In the above description, it has been described that after the mobile phone 20 notifies the user of an incoming mail, the mail reception process is performed when the user instructs to receive the mail. However, if the received mail is to be kept secret, It is desirable not to notify of incoming mail. In that case, when there is a notification of incoming mail from the portable mail server 40, the mobile phone 20 is set in advance so as not to notify the incoming call by sound or vibration, and the in-vehicle electronic mail communication device is connected via the connection cable. If the in-vehicle e-mail communication device 1 automatically performs reception processing, that is, processing from step S8 onward, the mobile phone connected to the passenger without being known to the passengers. Received mail can be transmitted.
[0048]
Also, in the above embodiment, the case where the mobile number permitted to transmit is specified has been described. However, if the connected telephone number is specified incorrectly, it is not transmitted. In the embodiment, instead of specifying a telephone number, it may be specified only whether or not transmission to a connected mobile phone is permitted.
[0049]
In the above embodiment, a case has been described in which the mail transmitted to the connected mobile phone is deleted from the recording unit 4 among the received mails. However, in another embodiment, the predetermined password is not deleted. May be set. For example, a password flag (initial value “0”) indicating the validity / invalidity of the password is provided in the received mail, a predetermined password setting is accepted in step S4, and “1” is set in the password flag instead of deleting the mail in step S14. Set. You can freely browse emails with the initial value “0” set in the password flag, but if you want to browse emails with the password flag set to “1”, the password set in step S4 An input request may be requested, and if the entered password is valid, it is possible to make it possible to view the mail.
[0050]
In the above embodiment, the case where the mail addressed to the mail address of the mobile phone 20 is received has been described. However, the mobile phone 20 is simply used as a modem to access the PC mail server 50 for a general computer. In the same way, the above processing can be performed. In that case, in order to confirm mail reception, the in-vehicle electronic mail communication apparatus 1 may access the PC mail server 50 with a predetermined user ID and password.
[0051]
In the above description, the case where the mail address of the connected mobile phone 20 is set as the unconditional transfer destination mail address set in step S4 has been described. However, the mobile phone other than the connected mobile phone 20 is connected. An e-mail address or an e-mail address used on a general computer can also be set.
[0052]
In the above description, the case where the user sets the unconditional forwarding destination e-mail address in step S4 has been described. However, it is set to perform unconditional forwarding upon accepting the setting as to whether or not to perform unconditional forwarding. Then, the in-vehicle electronic mail communication device 1 transmits the mail address of the mobile phone 20 acquired from the mobile phone 20 connected in step S2 to the PC mail server 50 as the transfer destination mail address in step S6. It may be.
[0053]
In step S6, when sending an unconditional forwarding mail address, the PC mail server 50 confirms whether or not the request is from a legitimate contractor based on the contract ID, and then changes the forwarding mail address. It is desirable to perform processing. In that case, for example, the in-vehicle electronic mail communication device 1 may perform a process of accepting an input of a contract ID in step S4, and transmit an email in which the contract ID is added to the information described in step S6. .
[0054]
FIG. 4 is a block diagram showing a state where the in-vehicle electronic mail communication apparatus according to the embodiment (2) is connected to a communication network via a mobile phone. The in-vehicle electronic mail communication apparatus 1A includes a CD-ROM drive 12, an audio processing unit 13, a speaker 14, and a CD-ROM 15 in addition to the same components as the in-vehicle electronic mail communication apparatus 1 shown in FIG.

[0058]
As a result, when it is determined that there is an email reception instruction, the email is received and recorded in the recording unit 4 (step S23). If the reception is normally completed, a message to that effect is displayed on the display unit 9, and it is determined whether or not there has been an operation for instructing the user to open the mail, that is, to view the mail (step S24).
[0059]
If it is determined that there is an email opening instruction, the contents of the email received in step S23 are displayed on the display unit 9 (step S25). At that time, “keyword extraction” and “cancel” buttons are displayed on the same image, and the user is instructed to perform keyword extraction (step S26). If it is determined that the “keyword extraction” button is not pressed and the “cancel” button is pressed, the process proceeds to step S33.
[0060]
The keyword is the two half-width symbols “ It is sandwiched between “<” and “>”. As a symbol for specifying a keyword, other symbols such as “%”, double-byte symbols, or a combination of a plurality of symbols can be used. For the keyword, it is possible to specify an arbitrary character string including an address, a building name, and a telephone number.
[0061]
If it is determined that the “keyword extraction” button has been pressed, the body of the email is searched using the specified symbol as a search key, a character string sandwiched between them is acquired, and a list of acquired character strings is displayed on the display unit 9. (Step S27) Waits for the user to select any keyword from the displayed keywords (Step S28).
[0062]
When it is determined that one keyword has been selected from the displayed keywords, the CD-ROM drive 12 is controlled and whether or not information related to the keyword is recorded in the inserted CD-ROM 15. Is determined (step S29). As the CD-ROM 15, for example, a CD-ROM for car navigation in which map information and various facility information are recorded can be used.
[0063]
