  Next, the operation of the vehicle information receiving system 1 configured as described above will be described with reference to the flowcharts of FIGS. The flowchart shown in FIG. 3 is a flowchart showing the operation of the mobile terminal 10, and is executed by the application 11. The flowchart shown in FIG. 4 is a flowchart showing the operation of the digital tachograph 20, and is executed by the CPU 21. The flowchart shown in FIG. 5 is a flowchart showing the operation of the handy ten key 40 and is executed by the CPU 41.

  This will be described from the flowchart of FIG. Note that the application 11 is activated in advance when the mobile terminal 10 is powered on or when the driver starts business. First, in step S101, it is determined whether or not an e-mail (office mail) that is instruction information from the operation management side is received. If an office mail is received (in the case of YES), the process proceeds to step S102. If it is not an office email (if NO), the process ends. Whether it is office mail or not may be determined from the received e-mail transmission source (From :), subject (Subject :), or the like. For example, if the sender is a specific sender, all may be determined to be office mail, or if the sender is a specific sender and the subject includes a specific keyword, it is determined to be office mail. May be.

  Next, in step S102, it is determined whether or not the audio output of the mobile terminal 10 is ON. If it is ON (in the case of YES), the process proceeds to step S103. If it is OFF (in the case of NO), the process proceeds to step S106. move on. In this step, the mobile terminal 10 has a function of converting the received e-mail into voice and outputting it from its own speaker. If the function is enabled (ON), the process from step S103 is executed. Then, the office mail received from the portable terminal 10 is output by voice. If the function of converting the received electronic mail into voice and outputting it from its own speaker is invalid (OFF), the digital tachograph 20 converts the office mail into voice and outputs it after executing step S106. Even when the mobile terminal 10 does not have a voice output function, this step is determined to be NO, and the process proceeds to step S106. That is, it is determined whether or not the instruction information can be output as an audio signal from itself, and if it is determined that the instruction information cannot be output as an audio signal, the instruction information is transmitted to the transmission means.

  Next, in step S103, it is determined whether or not the audio output timing is set for an incoming call. If it is set for an incoming call (YES), the process proceeds to step S105. If not (NO), step S104 is performed. Proceed to In this embodiment, the voice output timing at the time of office mail reception is set by selecting in advance whether to output immediately upon arrival or by trigger switch input described later, and refer to the setting in this step. To the step that matches your settings.

  Next, when a trigger switch input is made in step S104, the process proceeds to step S105. Like the trigger SW 27 described above, the trigger switch is a switch that serves as a trigger for outputting office mail, and is assigned to a predetermined button of the mobile terminal 10. The trigger switch may be a button displayed on a screen configured by a touch panel or the like, and is not limited to a button to be pressed, but may be input by a predetermined operation.

  Next, in step S105, the contents of the office mail text are converted into speech and output from the speaker of the portable terminal 10.

  On the other hand, in step S106, the office mail text is converted into text information, and the process proceeds to step S107. That is, only the text of the office mail is extracted and used as text information.

  Next, in step S107, the text information converted in step S106 is transmitted to the digital tachograph 20. Thereafter, processing is performed by the digital tachograph 20 shown in FIG.

  Next, the flowchart of FIG. 4 will be described. First, in step S201, it is determined whether or not the audio output timing is set for an incoming call. If the audio output timing is set for an incoming call (YES), the process proceeds to step S206. If not (NO), the process proceeds to step S202. move on. In this step as well as step S103, the digital tachograph 20 selects and sets in advance whether the voice output timing at the time of receiving the office mail is to be output immediately upon arrival or to be output by the trigger SW 27 input described later. Then, the process proceeds to the step suitable for the setting with reference to the setting. Note that the text information received from the mobile terminal 10 is held in the memory 23 of the digital tachograph 20 at the time of this step. That is, whether the instruction information is immediately converted into sound by the sound conversion means and output to the output means, or when the operation means is operated, the instruction information is converted into sound by the sound conversion means and output to the output means. Is set to Note that this setting may be switched using, for example, a button other than the trigger SW 27.

  Next, in step S202, a received message is displayed on the screen 30 (main body screen) of the digital tachograph 20, and the SW illumination 28 is turned on (or blinks), and the process proceeds to step S203. That is, it indicates that the instruction information has been received. The received message is a message indicating that the office mail is received, not the contents of the office mail. The received message is not limited to character information, but may be image information such as an icon.

  Next, in step S203, it is determined whether or not the handy key 40 is connected. If not (YES), the process proceeds to step S204. If connected (NO), step S203 is performed. The process proceeds to S207.

  Next, when the trigger SW 27 is input in step S204, the process proceeds to step S205. As described above, the trigger SW 27 is a switch serving as a trigger for outputting office mail.

  Next, in step S205, the received message displayed on the screen 30 (main body screen) of the digital tachograph 20 and the lighting (or blinking) of the SW illumination 28 are reset, and the process proceeds to step S206. That is, the received message is deleted and the SW illumination 28 is turned off.

  Next, in step S206, the contents of the office mail are converted into voice by the voice synthesis IC 24 and output from the speaker 25. Rather than suddenly outputting office email voice, output voice output confirmation sound such as “Beep from office” or warning sound such as “beep” before voice output. In this way, the driver's attention can be directed. Further, in this step, the timing for outputting the sound differs according to the determination in step S201. That is, the voice conversion means is caused to perform voice conversion based on the settings of the operation means and the timing setting means.

  On the other hand, in step S207, a signal indicating the presence of text data is transmitted to the handy ten key 40. Thereafter, processing is performed with the handy key 40 shown in FIG.

  Next, the flowchart of FIG. 5 will be described. First, in step S301, a received message is displayed on the LCD 46 (terminal screen) of the handy key 40, the SW illumination 44 is turned on (or flashes), and the process proceeds to step S302. The received message is a message indicating that the office mail has been received, not the contents of the office mail, as in step S202. The received message is not limited to character information, but may be image information such as an icon.

  Next, when the trigger SW 43 is input in step S302, the process proceeds to step S303. As described above, the trigger SW 43 is a switch serving as a trigger for outputting office mail.

  Next, in step S303, the received message displayed on the LCD 46 (terminal screen) of the handy key 40 and the lighting (or blinking) of the SW illumination 44 are reset, and the process proceeds to step S304. That is, the received message is deleted and the SW illumination 44 is turned off.

  Next, a trigger SW input signal is transmitted to the digital tachograph 20 in step S304. The operation of the handy numeric keypad 40 is up to this point, and thereafter, the process proceeds to step S205 in FIG.

  According to the above embodiment, when the mobile terminal 10 receives office mail and the mobile terminal 10 is set not to output voice, the office mail is converted into text information and transmitted to the digital tachograph 20. In the digital tachograph 20, when the voice output timing is an incoming call, it is immediately converted into a voice signal by the voice synthesis IC 24 and output from the speaker 25. Therefore, the mobile terminal 10 is a mobile phone already owned by the driver. It is only necessary to install the application 11 and the like, and the office mail received from the digital tachograph 20 is output as voice information, so that it is possible to confirm the contact and instruction contents without operating the mobile terminal 10 during operation or work.

  Further, since the office mail is converted into text information and transmitted to the digital tachograph 20 when the portable terminal 10 does not have a setting for voice output or does not have a function for voice output, the digital tachograph 20 is converted according to the function of the portable terminal 10. It is possible to switch whether or not to use the voice output function.

  When the digital tachograph 20 receives text information from the mobile terminal 10 and the voice output timing is not an incoming call, the received message is displayed on the screen 30, the SW illumination 28 is turned on, and the trigger SW 27 is operated. When the trigger SW 27 is operated, the office mail is output as voice information from the speaker 25 of the digital tachograph 20, so that the office mail is received and the office mail is displayed until the trigger SW 27 is operated. Can be made to stand by, and the instruction information can be confirmed without fail. In addition, since the office mail that has been voice-converted by the operation of the trigger SW 27 is output, the instruction information can be heard with a single button of the voice, and the trouble of confirming the instruction information can be reduced.

  Further, the handy ten key 40 is connected to the digital tachograph 20, and when the digital tachograph 20 receives text information, a reception message is displayed on the LCD 46 of the handy ten key 40, the SW illumination 44 is turned on, and the trigger SW 43 is turned on. Since the operation is urged, if the handy key 40 is held, the reception of the office mail can be grasped even if it is not near the digital tachograph 20. Even if the handy ten key 40 is connected, the voice output operation from the handy ten key 40 may not be performed. This can be switched from the digital tachograph 20 or the handy ten key 40.

  In the above-described embodiment, the text of the office mail received by the mobile terminal 10 is automatically converted into an audio signal. However, a portion to be converted into an audio signal may be designated. More specifically, when an e-mail is transmitted from the office terminal 50, a predetermined symbol is inserted and specified at the beginning and the end of a portion to be converted into a voice signal into text information. For example, if the symbol indicating the beginning of the part to be converted into a voice signal is “− ++” and the symbol indicating the end of the part to be converted into a voice signal is “++ −”, “…… Please contact the office +++ -... "so that only the part" Please contact the office by XX "is converted into text information by the application 11 of the mobile terminal 10, and the digital tachograph 20 is output. That is, the office terminal 50 functions as a conversion range designation unit and an insertion unit.

  By doing in this way, only the content which wants to be transmitted to a driver | operator reliably, or the content which wants to emphasize more can be converted into an audio | voice signal. Also, whether to convert only a part of the office mail into an audio signal or convert the entire text into an audio signal using this symbol may be performed by the digital tachograph 20, for example, the CPU 21 of the digital tachograph 20 If there is such a symbol, only that portion may be extracted and output to the speech synthesis IC 24, and if there is no such symbol, the entire text may be output to the speech synthesis IC 24. Moreover, the insertion of the symbols is not limited to manual operation. For example, a plurality of sentence templates may be prepared in advance at the office terminal 50, and the symbols may be automatically inserted before and after the selected template.

  Further, the office mail once voice-outputted may be output again. For example, when the digital tachograph 20 main body or the handy ten key 40 is provided with a re-output button or the like and the re-output button is operated, the voice synthesis IC 24 converts the text information into a voice signal again and outputs it from the speaker 25. Alternatively, the converted audio signal (audio data) may be stored in a memory or the like, and when the re-output button is operated, the audio signal stored in the memory may be output. That is, the operation means includes a re-output means for outputting again the audio signal output from the output means.

  In addition, when audio is output from the digital tachograph 20, the CPU 21 notifies the mobile terminal 10 that the audio is output via the communication I / F 22, and the application 11 of the mobile terminal 10 receives the notification. The office mail output as voice may be treated as read. By doing so, it is not necessary to operate the mobile terminal 10 to read the office mail output as voice. That is, the CPU 21 functions as a notification means for notifying the mobile terminal 10 that the digital tachograph 20 has output the sound, and when the application 11 receives the notification from the CPU 21, the instruction information output by the sound is treated as already read. It has changed.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
