Example 1
Before specifically describing the first embodiment of the present invention, an outline of the first embodiment will be described. The present embodiment relates to a communication system including an in-vehicle device and a communication device connectable to the in-vehicle device in a vehicle. The in-vehicle device includes a display and is configured to display an image. An example of a communication device is a wireless device, particularly a smart phone, which executes various applications. An application executed in the communication device outputs image data to the in-vehicle device, and the in-vehicle device displays the image data. If the application executed in the communication device is a television broadcast receiving function, it is desirable that the image data is not displayed during traveling in consideration of safety during traveling of the vehicle. On the other hand, some applications executed in the communication device preferably display image data even while traveling. For example, a car navigation application.

  In order to deal with such a situation, the in-vehicle device stops displaying the input image data while traveling. Further, the communication device determines the type of application being executed. When the application type is the in-vehicle application, the communication device outputs a request signal for canceling the suspension of the display of the image data to the in-vehicle device. When the request signal is input, the in-vehicle device displays the input image data by canceling the cancellation of the display of the image data.

  FIG. 1 shows a configuration of a communication system 100 according to Embodiment 1 of the present invention. The communication system 100 includes a communication device 10 and an in-vehicle device 12. The communication device 10 can be mounted on the vehicle 14. The communication device 10 can be connected to the in-vehicle device 12. Here, the communication device 10 and the in-vehicle device 12 include a bidirectional communication line (hereinafter referred to as “first line”) and a unidirectional communication line from the in-vehicle device 12 to the communication device 10 (hereinafter referred to as “second line”). "). The first line and the second line may be wireless or wired. A control signal is transmitted between the communication device 10 and the in-vehicle device 12 on the first line. Image data is transmitted from the communication device 10 to the in-vehicle device 12 on the second line.

  The in-vehicle device 12 inputs the image data from the communication device 10 through the second line. The image data should be originally displayed on the display of the communication device 10. The in-vehicle device 12 displays the input image data. On the other hand, when the in-vehicle device 12 determines that the vehicle 14 is traveling, the on-vehicle device 12 stops displaying the image data. The communication device 10 determines the type of application being executed. Here, the application being executed is an application that outputs image data to the in-vehicle device 12.

  When the determination result is the in-vehicle application, the communication device 10 outputs a request signal to the in-vehicle device 12 through the first line. As described above, the in-vehicle application is an application that should display image data even while the vehicle 14 is traveling. The request signal is one of the control signals, and is a signal for requesting the in-vehicle device 12 to display image data even while the vehicle 14 is traveling. When the request signal is input, the in-vehicle device 12 continues to display the input image data even when the vehicle 14 is traveling.

  FIG. 2 shows another configuration of the communication system 100 according to the first embodiment of the present invention. The communication device 10 includes an application information storage unit 20, a monitoring unit 22, a communication unit 24, a video / audio output unit 26, and an application processing unit 28, and the communication unit 24 includes a request output unit 30. The in-vehicle device 12 includes a travel determination unit 40, an instruction unit 42, a communication unit 44, a video / audio input unit 46, an output switching unit 48, and a display unit 50, and the communication unit 44 includes a request input unit 52.

  The communication device 10 is a wireless device corresponding to a terminal device of a mobile phone system. Here, description of communication processing corresponding to the mobile phone system is omitted. The application processing unit 28 executes various application programs. Applications are classified into a plurality of types. Here, in order to clarify the explanation, the applications are classified into in-vehicle applications and non-in-vehicle applications. The in-vehicle application includes a navigation application. Moreover, even if it is a communication application such as e-mail, an application designed to facilitate visual recognition within the vehicle 14 is also included in the in-vehicle application. The design for facilitating visual recognition corresponds to reducing the number of characters shown on the display than usual. The application processing unit 28 outputs image data generated by processing the application to the video / audio output unit 26. When the application is navigation, the image data corresponds to a map image showing a route. The image data includes both an image to be shown on the display and electronic data corresponding to the image.

The video / audio output unit 26 outputs the image data from the application processing unit 28 to the video / audio input unit 46. The space between the video / audio output unit 26 and the video / audio input unit 46 corresponds to the second line described above.

  The monitoring unit 22 determines the type of application that is being executed by the application processing unit 28 and that is outputting image data to the in-vehicle device 12. In order to determine the type of application, a table stored in the application information storage unit 20 is used. FIG. 3 shows the data structure of the table stored in the application information storage unit 20. Such a table is stored for each application. As illustrated, an information column 200 and a content column 202 are included. As an example, the application name is indicated as “A” and the version is indicated as “B”. The application type is indicated as an in-vehicle application or a non-in-vehicle application. The non-vehicle application may be shown in more detail. Further, only the in-vehicle application is described, and those not in the table may be non-in-vehicle applications. At that time, the application type is used to subdivide the in-vehicle application. For example, there are an in-vehicle application manufactured by company A and an in-vehicle application manufactured by another company. The capability indicates whether the vehicle information communication is supported and whether the destination information communication is supported. These will be described later. Returning to FIG.

  If the monitoring unit 22 determines that the application is an in-vehicle application by referring to the table shown in the application information storage unit 20, the monitoring unit 22 outputs a message to that effect to the request output unit 30. The communication unit 24 is connected to the communication unit 44. The communication unit 24 and the communication unit 44 correspond to the first line described above, and the communication method is, for example, USB (Universal Serial Bus). Note that a device other than USB may be used for the first line. The request output unit 30 outputs a request signal to the request input unit 52 via the first line when receiving a notification from the monitoring unit 22 that it is an in-vehicle application. When the determination result in the monitoring unit 22 is an application that should display image data even while the vehicle 14 is traveling, the in-vehicle device 12 is requested to display the image data even while the vehicle 14 is traveling. Equivalent to.

  The video / audio input unit 46 inputs the image data from the video / audio output unit 26. The video / audio input unit 46 outputs the image data to the output switching unit 48. The output switching unit 48 receives the image data from the video / audio input unit 46 and outputs the image data to the display unit 50. The display unit 50 displays the image data input from the output switching unit 48 on the display. The traveling determination unit 40 inputs information related to the speed of the vehicle 14 from a vehicle speed sensor or the like provided in the vehicle 14. The traveling determination unit 40 determines whether or not the vehicle 14 is traveling based on the information regarding the speed. More specifically, the traveling determination unit 40 defines a threshold value, and determines that the vehicle 14 is traveling when the information regarding the speed is higher than the threshold value. On the other hand, the traveling determination unit 40 determines that the vehicle 14 is not traveling if not. The traveling determination unit 40 may also monitor the parking brake state and determine whether or not the vehicle is traveling according to this. At that time, when the parking brake is off and the speed is higher than the threshold, the traveling determination unit 40 determines that the vehicle 14 is traveling. The travel determination unit 40 outputs a determination result (hereinafter referred to as “travel information”) to the instruction unit 42.

  The instruction unit 42 outputs a stop signal for causing the display unit 50 to stop displaying the image data to the output switching unit 48 when the travel information indicates travel. The output switching unit 48 does not output the image data from the video / audio input unit 46 to the display unit 50 when a stop signal is input from the instruction unit 42. As a result, the display unit 50 does not display the image data on the display. The communication unit 44 executes processing corresponding to the communication unit 24. The request input unit 52 inputs a request signal from the request output unit 30. This corresponds to inputting a request signal from the communication device 10 when the image data from the communication device 10 is image data by an in-vehicle application. The request input unit 52 outputs a request signal to the instruction unit 42. When the request signal from the request input unit 52 is input, the instruction unit 42 does not output a stop signal to the output switching unit 48 even if the travel information is travel. This corresponds to canceling the suspension of the display of the image data when a request signal is input.

  Note that the travel information determined by the travel determination unit 40 is output to the monitoring unit 22 via the communication unit 44 and the communication unit 24. These outputs are made periodically. Based on the travel information, the monitoring unit 22 detects the transition from running to stop or detects the transition from stop to running. The monitoring unit 22 executes the above-described process when a transition is detected. Moreover, the monitoring part 22 may perform the above-mentioned process regularly.

  This configuration can be realized in terms of hardware by a CPU, memory, or other LSI of any computer, and in terms of software, it can be realized by a program loaded in the memory, but here it is realized by their cooperation. Draw functional blocks. Accordingly, those skilled in the art will understand that these functional blocks can be realized in various forms only by hardware, or by a combination of hardware and software.

  The operation of the communication system 100 configured as above will be described. FIG. 4 is a sequence diagram illustrating a transmission procedure performed by the communication system 100. Communication device 10 and in-vehicle device 12 are connected (S10). The communication device 10 transmits capability information to the in-vehicle device 12 (S12). The communication device 10 transmits request information to the in-vehicle device 12 (S14). The communication device 10 transmits image data to the in-vehicle device 12 even when traveling (S16).

  FIG. 5 is a flowchart showing a transmission procedure by the communication apparatus 10. If there is no change in the running state (N in S20) and the regular time has not elapsed (N in S22), the process returns to Step 20. When the running state has changed (Y in S20), or when the regular time has elapsed (Y in S22), the monitoring unit 22 determines the type of the application, so that the in-vehicle application is operating (S24). Y), the request output unit 30 transmits a request signal (S26). If the in-vehicle application is not operating (N in S24), step 26 is skipped. If the connection is not terminated (N in S28), the process returns to step 20. If the connection is terminated (Y in S28), the process is terminated.

  FIG. 6 is a flowchart showing a display procedure by the in-vehicle device 12. If the request input unit 52 does not receive the request signal (N in S30) and is traveling (Y in S32), the display unit 50 stops the display (S34). When the request input unit 52 receives the request signal (Y in S30), or when it is not running (N in S32), the display unit 50 displays (S36). If the connection is not terminated (N in S38), the process returns to step 30. If the connection is terminated (Y in S38), the process is terminated.

  According to the embodiment of the present invention, since the display is stopped during traveling, safe driving can be executed. Further, in the case of an in-vehicle application, a request signal for continuing the display is transmitted even during traveling, so that the image data of the in-vehicle application can be displayed during traveling. Moreover, since it changes whether it displays according to the kind of application, the display according to a condition can be performed. In addition, since a non-in-vehicle application is not displayed during traveling, even a non-in-vehicle application can perform cooperation between the in-vehicle device and the communication device in compliance with the travel regulations.

As in the first embodiment, the second embodiment also relates to a communication system that includes a vehicle-mounted device and a communication device that can be connected to the vehicle-mounted device. Also in the second embodiment, the image data of the in-vehicle application is displayed even while traveling, but the image data of the non-in-vehicle application is not displayed during traveling. On the other hand, in the second embodiment, even if it is an in-vehicle application that should be displayed even while traveling, if the travel regulation is performed, the travel regulation process according to the travel regulation is executed for the in-vehicle application. When the in-vehicle application is navigation, the destination cannot be input during traveling by the travel regulation process. Since such travel regulations differ depending on the country and the automobile manufacturer, information on these is output from the in-vehicle device to the communication device. In the communication process, the travel restriction process is executed based on the information related thereto. The communication system 100 according to the second embodiment is the same type as that shown in FIG. Here, it demonstrates centering on the difference from before.

The manufacturer of the vehicle 14 is indicated by the destination (manufacturer). The vehicle information indicates a vehicle (SPD) and a vehicle (PKB). The vehicle speed value of the vehicle 14 is indicated by the vehicle (SPD). The vehicle (PKB) indicates whether the parking brake is on or off. Returning to FIG. In the second embodiment, vehicle information is not output.

  The information input unit 32 inputs destination information from the information output unit 54. The information input unit 32 outputs the destination information to the instruction unit 34 and also outputs the travel information to the instruction unit 34. The instruction unit 34 stores in advance a travel regulation process corresponding to each destination information. The instruction unit 34 selects a travel regulation process corresponding to the destination information from the information input unit 32. When the travel information from the information input unit 32 indicates travel, the instruction unit 34 instructs the application processing unit 28 to execute the selected travel restriction process.

  When the application processing unit 28 receives an instruction from the instruction unit 34, the application processing unit 28 also executes the selected travel restriction process when executing the in-vehicle application. As described above, the travel regulation process is a process for stopping some functions of the in-vehicle application. The application processing unit 28 outputs the image data that has also undergone the travel restriction process to the video / audio output unit 26. This image data is also displayed on the display unit 50.
