  The in-vehicle audio unit 11 is a processing unit that performs reproduction of music data and video data, reception of radio broadcasting, television broadcasting, and the like. The navigation unit 12 is a processing unit that specifies position information of the host vehicle using a GPS artificial satellite or the like, guides a route to the destination, and provides information related to the area for traffic.

  The input unit 13 is a processing unit that performs user input to the in-vehicle device, and is realized by a switch, a touch panel display, or the like. The display 14 is a display output unit using a display medium such as a liquid crystal panel. The speaker 15 is sound output means for outputting sound to the vehicle interior.

  The communication unit 16 is a processing unit that performs communication connection with the mobile terminal devices 40a, 40b, and 40c, and the control table 17 is a table that is used when the output control unit 20 controls display output.

  The output control unit 20 is a control unit that integrally manages input / output of the in-vehicle device 10, particularly display output, and functions as an in-vehicle display control device. The output control device 20 includes a vehicle state determination unit 21, an information type determination unit 22, and a display image generation unit 23 as components that are particularly important in the present invention.

  The vehicle state determination unit 21 acquires information from the vehicle speed sensor 31, the engine control ECU 32, the brake control ECU 33, the parking brake 34, the in-vehicle audio unit 11, and the navigation unit 12, and determines the state of the host vehicle.

  Further, the information type determination unit 22 recognizes the type of information (traffic information, video, music, etc.) received by the communication unit 16 from the mobile terminal devices 40a, 40b, and 40c. For the recognition of this information type, identification information may be added in advance on the mobile terminal device side, or the type may be recognized by analyzing the information on the in-vehicle device side.

  The display image generation unit 23 is a processing unit that generates a display image to be displayed on the display 14. Specifically, the display image generation unit 23 refers to the control table 17 based on the state of the host vehicle and the information type, controls the display mode of each display output, and generates a display image.

  FIG. 2 is an explanatory diagram illustrating a specific example of a display image created by the display image generation unit 23. In the example shown in the figure, in addition to the navigation display 14a that is a display output used for navigation (route guidance), the display 14 receives the received image data 41a received from the mobile terminal device 40a and the mobile terminal device 40b. The received image data 41b and the received image data 41c received from the mobile terminal device 40c are displayed.

  Here, the received image data 41a uses a display area larger than the received image data 41b and 41c. The difference in the size of the display area is determined based on the vehicle state and the information type. is there.

  FIG. 3 is an explanatory diagram illustrating a specific example of the control table 17. In the control table shown in the figure, three types of information types are “traffic information”, “video”, and “music”, and vehicle states are “Naviroute setting”, “High speed driving”, “Steep curve driving” Or, the number of times the brake is operated within a certain period of time is more than a certain number, “running off the set route”, “playing music or video on the vehicle”, “operating parking brake”, “braking brake”, “ Eight states of “passing the dangerous part” are used as judgment materials.

  Specifically, when “navigating route is being set”, that is, when the navigation unit 12 sets a route to the destination and performs route guidance processing, the traffic information is preferentially displayed even if communication is not active, Video and music are displayed on a small screen. Thereby, a user can be notified of traffic information in real time at the time of route setting.

  In addition, when it is recognized that the vehicle is “at high speed” from the vehicle speed information from the vehicle speed sensor 31 or the information from the navigation unit 12 (type information of the traveling road), the traffic information is voiced with text information added as a display. Only video, video cannot be displayed, and music only audio is output and cannot be displayed. Thereby, a driver | operator's eyes | visual_axis movement can be prevented and it can contribute to safe driving | operation. In addition, when notifying emergency information (for example, passage of an ambulance or occurrence of an earthquake), it is possible to assist by avoiding danger by making a large notification using the display area.

  Further, when the vehicle is “running a sharp curve” based on position information, map information, steering wheel operation state, gyro sensor, or the like output from the navigation unit 12, or “operating the brake within a predetermined time” from the operation state of the brake control ECU 33. When the number of times is equal to or greater than a certain number, the received data from the mobile terminal device is not displayed. As a result, the driver can be concentrated on the driving operation.

  In the case of “running off the set route”, traffic information is preferentially displayed even if communication is not active, and moving images and music are displayed on a small screen. Thereby, driving operation in consideration of real-time traffic information can be supported.

  In addition, when “on-vehicle device (vehicle audio device 11) is playing music or video”, traffic information is displayed on a small screen, and video and music are displayed on a small screen with received information (video or music title, etc.). The reproduction output can be selected by the user operation.

  Further, when “the parking brake 34 is in operation”, that is, when the parking brake 34 is parked, the active one of the mobile communication terminals is displayed on the full screen.

  In addition, when the position information or map information output from the navigation unit 12 indicates “passing the dangerous part”, the reception data from the mobile terminal device is not displayed.

  FIG. 4 is an explanatory diagram for explaining the operation timing of the output control unit 20. In the example shown in the figure, first, the communication unit 16 is connected to the device A at time t1, communication is established at time t2, data identification information (ID) is acquired at time t3, and device A from time t4. The data received from is displayed on the screen.

  Thereafter, if the communication unit 16 connects to the device B at time t5, communication is established at time t6, and data identification information (ID) is acquired at time t7, the data are received from the devices A and B from time t8. Display the combined data together on the screen.

  Further, when the communication with the device A is completed at the time t9, the data received from the device B from the time t10 is displayed on the screen. This screen display is continued until communication with the device B is completed at time t11.

  Next, the processing operation of the output control unit 20 will be described with reference to FIG. The flowchart shown in FIG. 5 is a main flow that the output control unit 20 repeatedly executes.

  The output control unit 20 first determines whether or not the communication unit 16 has received data (display information) to be displayed from the mobile terminal information (step S101). If not received (step S101, No), it remains as it is. The process ends.

  On the other hand, when display information is received (step S101, Yes), the vehicle state determination part 21 acquires a vehicle state (step S102), and refers to the control table 17 using the received display information type and vehicle state. (Step S103).

  The display image generation unit 23 determines the display mode of each display information using the reference result of the control table, creates a display screen (step S104), performs display output, and ends the process.

  As described above, in the in-vehicle device 10 according to the present embodiment, when the information received from the portable information terminal is displayed and output, the traveling state of the host vehicle is determined and displayed using the traveling state and the information type. Control the output mode. Therefore, it is possible to provide a plurality of screen data in a form suitable for the traveling state of the vehicle so that the user can easily grasp the screen data.

  Note that the configuration and operation shown in this embodiment are merely examples, and the present invention can be implemented by appropriately changing the configuration and operation. For example, FIG. 1 illustrates an example in which the present invention is applied to a vehicle-mounted device incorporating a vehicle-mounted audio unit and a navigation unit. However, the device does not have these functions and is specialized for input / output control. The present invention can also be applied.

  The in-vehicle device 10a illustrated in FIG. 6 is a configuration example in the case where the mobile terminal device 40a performs navigation of the vehicle without including the in-vehicle audio unit and the navigation unit. In the configuration shown in the figure, the display control unit 20a supplies the navigation information received from the mobile terminal device 40a to the vehicle state determination unit 21 for use in determination of the vehicle state, and also supplies it to the information type determination unit 22. It is treated as one piece of information to be displayed. In the case where the external device performs the navigation function in this way, the type of information related to navigation may be “traffic information”, but it is desirable that the navigation information be defined as a different type.

  Since other configurations and operations are the same as those of the in-vehicle device 10 shown in FIG. 1, the same components are denoted by the same reference numerals and description thereof is omitted.

  As described above, the vehicle-mounted display control device and the vehicle-mounted display control method according to the present invention are useful for display control of a vehicle-mounted display, and are particularly suitable for display control of data received from a mobile terminal device.
