A unique button ID is assigned to each button, and the processing desired by the user can be specified from the button ID.

  The button ID for each button and the information for specifying the process corresponding to the button may be stored in the ROM or meter memory. The button ID of the button displayed on the center display 12 and the button ID of the button displayed on the meter display 23 may be the same or associated with each other. Details of the operation of the meter-side display control unit G1 will be described later.

  The meter-side operation accepting unit G2 accepts an operation by the driver for using the functions of the multimedia unit 10 or the portable terminal 40 via the steering switch 30. The functions provided in the multimedia unit 10 or the portable terminal 40 are functions that can be used by the user in the passenger compartment, such as the navigation function and the audio function described above. This meter side operation reception part G2 is equivalent to the 2nd operation reception part as described in a claim.

  The operations for using these functions include the movement of the cursor (or item) based on the push operation to the direction keys 32U to 32R and the selection operation of a desired button based on the push operation to the enter key 31. Point to. That is, it refers to an operation for selecting a desired function from a plurality of functions such as a navigation function and an audio function, a selection operation for executing a finer process belonging to the selected function (for example, selection of music), and the like. The operation of pushing the enter key 31 and selecting a desired button (that is, an item) corresponds to an example of an instruction operation described in the claims.

  Further, the meter side operation accepting unit G2 generates information (meter side operation information) indicating the content of the instruction operation by the driver accepted via the steering switch 30, and the multimedia unit via the meter side communication processing unit G3. 10 to provide. Similarly to the MM side operation information, the meter side operation information may be the button ID of the button selected by the driver.

  The meter side communication processing unit G3 performs communication processing with the multimedia unit 10. For example, the meter side operation information provided from the meter side operation reception unit G2 is transmitted to the multimedia unit 10. The meter side communication processing unit G3 acquires MM side operation information and display output data input from the multimedia unit 10. When the MM side operation information is acquired from the multimedia unit 10, the meter side communication processing unit G3 provides the MM side operation information to the meter side display control unit G1. Along with this, the meter-side display control unit G1 controls the display content of the meter display 23. The meter side communication processing unit G3 corresponds to the meter side communication unit described in the claims.

(About operation of MM side display controller F5)
Here, the operation of the MM side display control unit F5 will be described in more detail. The MM side display control unit F5 displays the main display unit illustrated in FIG. 3 immediately after activation of the multimedia unit 10 or when a predetermined process (for example, a route guidance process) is not executed. A predetermined image corresponding to the menu screen is displayed as a steady display image. The steady display image here refers to an image to be displayed when a user does not perform an instruction operation for a certain period of time (a holding time described later).

  When an instruction operation is performed by the user via the multimedia operation unit 14 or the steering switch 30, an image based on display output data output from the function provider is generated according to the instruction operation. And displayed on the center display 12. Hereinafter, an image displayed based on a user's instruction operation is also referred to as an operation-compatible image.

  Here, when the type of display output data input based on the instruction operation by the user (that is, the type of image to be displayed) is a predetermined type, the MM side display control unit F5 The operation corresponding image displayed based on the display output data is adopted as the steady display image. The type of image adopted as the steady display image is an image that does not require a subsequent user instruction operation such as a surrounding map image, a route guidance image, a music reproduction image, and a moving image reproduction image. The route guidance image is an image displayed based on display output data output while the navigation processing unit F1 executes the route guidance processing, and is an image that guides the driving route to the driver. The music playback image is an image showing information about the music data being played back.

  In addition, an image for setting a destination belonging to the navigation function, an image for selecting a music file to be played belonging to the audio function, and the like are images that require a subsequent user operation, and are displayed as steady display images. Shall not apply.

  When a plurality of display output data corresponding to the steady display image are input, an image corresponding to each of the display output data is displayed on the center display 12 with a predetermined layout. Just do it. A method for displaying an image corresponding to each of a plurality of types of functions may be realized with the aid of a well-known method as disclosed in, for example, WO 2006/022191.

  In addition, when the operation-corresponding image displayed based on the instruction operation by the user is a type of image that does not correspond to the steady display image, the MM side display control unit F5 displays the image for a certain time (referred to as a holding time). The display of the operation-compatible image is canceled. Here, the holding time may be a predesigned time, and is assumed to be 3 seconds as an example here. In addition, when the display of the operation corresponding image is canceled, the steady display image is displayed in a predetermined layout.

  However, a new instruction operation (referred to as a subsequent instruction operation) related to the instruction operation (referred to as the previous instruction operation) that has triggered the display of the operation-compatible image within the holding time after the operation corresponding image is displayed. If it has been performed, the operation corresponding image resulting from the subsequent instruction operation is displayed in the area where the original operation corresponding image was displayed. That is, while the user continues to perform an instruction operation for the same function, the display of the image corresponding to the function is continued.

  The image displayed using the previous instruction operation as a trigger and the image displayed using the subsequent instruction operation as a trigger may be the same image. Further, in the present embodiment, when an instruction operation for the same function by the user is continuously executed, an image displayed as an operation corresponding image is sequentially updated to an image corresponding to each instruction operation. Not limited to this. While the user continues to perform the instruction operation for the same function, the same image may be continuously displayed.

  Whether or not the user continues the instruction operation for the same function may be determined based on the elapsed time since the previous instruction operation was input. For example, if the subsequent instruction operation is not performed within the holding time after the previous instruction operation is input, it may be determined that the user does not continue the instruction operation for the same function (that is, has been interrupted). .

  The new instruction operation related to the previous instruction operation includes an operation for performing the new instruction operation (referred to as a preliminary operation). The preliminary operation includes a cursor movement, a screen scroll operation, an enlarged / reduced display operation of the operation mode image, a character input operation, and the like.

  A flow of a series of processes performed by the MM side display control unit F5 described above will be described with reference to FIGS. 7, 8, and 9. FIG. FIG. 7 is an example of a display screen of the center display 12 when the route guidance image Im1 is displayed. Here, it is assumed that the route guidance image Im1 is adopted as a steady display image.

  In the state shown in FIG. 7, when the user selects and operates the button B2 for using the audio function, the MM-side display control unit F5 uses the display output data provided from the audio processing unit F2 as shown in FIG. The audio menu image Im2 shown in FIG. Note that the audio menu image Im2 is an image that does not correspond to the steady display image, and is an image that includes buttons B21 to B26 for selecting a desired subfunction among various subfunctions included in the audio processing unit F2. . In the present embodiment, as an example, an operation corresponding image that does not correspond to a steady display image is displayed as a pop-up on the steady display image.

  If a new instruction operation is performed on the audio processing unit F2 within the holding time after the audio menu image Im2 is displayed, a new instruction operation is performed in the area displaying the audio menu image Im2. The operation corresponding image Im3 corresponding to is displayed. That is, the display content in the pop-up window is changed while maintaining the display of the pop-up window.

  On the other hand, if a new instruction operation is not performed on the audio processing unit F2 within a certain time after the audio menu image Im2 is displayed, the pop-up window corresponding to the audio function is terminated, and FIG. Return to the display screen shown in.

  Note that the case where the instruction operation is received as described above is not only the case where the user performs an instruction operation via the multimedia operation unit 14, but also because the instruction operation via the steering switch 30 is performed by the driver. This is also the case. That is, even when meter-side operation information is input from the meter unit 20, the same operation as when the MM-side operation reception unit F6 receives an instruction operation by the user is performed.

(About operation of meter side display control part G1)
Next, the operation of the meter side display control unit G1 will be described. The meter-side display control unit G1 also displays an image corresponding to an instruction operation by the user (that is, an operation-corresponding image) on the meter display 23 as described above.

  The meter side display control unit G1 also sets and displays a steady display image on the meter display 23 as appropriate, similarly to the MM side display control unit F5. For example, immediately after the meter unit 20 is activated, a preset image is displayed as a steady display image. Thereafter, when a predetermined type of operation-corresponding image is displayed, the operation-corresponding image is adopted as a steady display image.

  The steady display image for the meter side display control unit G1 is an image that is displayed when an instruction operation is not performed by the user for a predetermined holding time, similarly to the steady display image for the MM side display control unit F5. . Note that the holding time of the meter-side display control unit G1 may be different from the holding time for the MM-side display control unit F5 (for example, 4 seconds).

  Incidentally, the meter display 23 is a display that is disposed in the driver's field of view and is conventionally disposed in an area for displaying vehicle information. Accordingly, the type of image corresponding to the steady display image on the meter display 23 is preferably an image of a type that supports the driving operation of the driver, such as an image that guides the travel route. The image that is displayed as a steady display image in the initial state is an image that represents information on the vehicle's shift position, azimuth angle, outside air temperature, vehicle interior temperature, and the like, and information on the environment outside and inside the vehicle interior. And it is sufficient. The steady display image may be changed based on a user operation.

  Here, the operation of the multimedia unit 10 and the meter unit 20 when the multimedia operation unit 14 is operated by the user will be described with reference to FIGS. 10 and 11. Here, as an example, it is assumed that the display screen of the center display 12 displays the route guidance image Im1 shown in FIG. 7 as a steady display image. That is, the navigation processing unit F1 is executing the route guidance process based on an instruction operation by the user, and the display output data corresponding to the route guidance process is being output.

  When the MM side display control unit F5 displays the route guidance image Im1 on the center display 12, the meter side display control unit G1 also displays a simple route guidance image Im1a corresponding to the route guidance image Im1. This simple route guidance image Im1a is an image for guiding the driving route to the driver.

  In the present embodiment, images displayed on the meter display 23 and the center display 12 are images having different display modes as images corresponding to the route guidance processing, but the present invention is not limited to this. As another aspect, the same image (for example, route guidance image Im1) may be displayed on each of the meter display 23 and the center display 12.

  In the state shown in FIG. 7, when the user (for example, a passenger in the passenger seat) touches the button B2 for using the audio function, the multimedia unit 10 indicates that the button B2 has been operated. The side operation information is transmitted to the meter unit 20.

  When the meter-side display control unit G1 acquires the MM-side operation information, the meter-side display control unit G1 generates an image corresponding to the user operation received by the MM-side operation reception unit based on the MM-side operation information and displays the image on the meter display 23. The user operation accepted by the MM side operation accepting unit here is an operation for using the audio function. That is, the meter-side display control unit G1 also displays an audio menu image Im2a that is an image including buttons B21 to B26 for selecting a desired sub-function among various sub-functions included in the audio processing unit F2. (See FIG. 11). The audio menu image Im2a is an image corresponding to the aforementioned audio menu image Im2 (FIG. 8).

  Since the audio menu image Im2a is not a steady display image, the meter-side display control unit G1 has not received a new operation instruction belonging to the audio function within the holding time after displaying the audio menu image Im2a. The display of this image is canceled. In that case, the display screen of the meter display 23 returns to the screen shown in FIG.

  Further, when a new operation instruction belonging to the audio function is given within the holding time after the audio menu image Im2a is displayed, an image related to the audio function is continuously displayed. That is, the display of the image related to the audio function is continued.

(Summary of embodiment)
According to the above configuration, an image corresponding to an operation performed by the user on the multimedia operation unit 14 is displayed not only on the center display 12 but also on the meter display 23. For example, when the passenger on the passenger seat performs an operation of selecting the button B2 for using the audio function on the multimedia operation unit 14, the audio menu image Im2a is displayed on the meter display 23.

  The driver recognizes that the audio menu image Im2a is displayed on the meter display 23, and paradoxically recognizes that the passenger in the passenger seat has performed an operation for using the audio function. Can do.

  In addition, regarding an operation corresponding image that is not designated as a steady display image, if a subsequent instruction operation is not performed before a predetermined holding time elapses after display, the display ends. Therefore, the image corresponding to the interrupted operation is not displayed indefinitely, and the visibility of the steady display image can be improved. In the meter display 23, the visibility of vehicle information and the like can be improved.

  Further, when a subsequent instruction operation is performed via the multimedia operation unit 14 after the operation-supporting image is displayed and a predetermined holding time elapses, an image of the function operated by the user on the meter display 23 Continue to display. Therefore, it is possible to prevent the image regarding the function being operated from being displayed on the meter display 23 even when the operation is being continued.

  Furthermore, if the display of all the operation-corresponding images is canceled after a certain time has elapsed since the display of the images, images corresponding to the route guidance process will not be displayed. Therefore, in the present embodiment, an image (that is, a steady display image) that continues to be displayed even after a predetermined time has elapsed since the start of display is set in advance, and the operation-corresponding image displayed based on the instruction operation by the user When it corresponds to the display image, the display of the image is continued. By setting it as such an aspect, a user's convenience can be improved.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, The following modification is also contained in the technical scope of this invention, Furthermore, the summary other than the following is also included. Various modifications can be made without departing from the scope.

<Modification 1>
In the above, when the type of image to be adopted as the steady display image is determined in advance, and the operation corresponding image displayed using the user's instruction operation as a trigger corresponds to the steady display image, the operation corresponding image is displayed as a steady display. The aspect employ | adopted as an image was illustrated. In other words, when the operation corresponding image displayed using the instruction operation by the user as a trigger is an image of a predetermined type, the display is continued even after the holding time has elapsed, and the operation corresponding image belonging to another function is displayed. The mode employ | adopted as an image displayed when canceling | released was illustrated.

  However, the operation of each display control unit is not limited to this. For example, as long as the subsequent operation is not performed within the holding time after displaying all the operation-corresponding images, the display may be canceled after the holding time has elapsed since the display. The image displayed after the display of the operation-compatible image may be an image of a type designated by the user before the operation-compatible image is displayed.

<Modification 2>
In the above-described embodiment, the display mode of the operation corresponding image on the center display 12 has been illustrated as being superimposed on the steady display image, but is not limited thereto. As illustrated in FIG. 12, the MM side display control unit F5 may display an operation corresponding image corresponding to an instruction operation by the user side by side on another image (that is, a steady display image). The layout of the display screen of the center display 12 (the arrangement and display size of each image) may be determined according to the combination of the types of images to be displayed. 12 is a screen corresponding to FIG. 8 and is displayed when the button B2 is selected in the situation where FIG. 7 is displayed.

<Modification 3>
In general, the in-vehicle device incorporates a function (that is, a travel forcing function) that prohibits execution of a predetermined process when the vehicle is traveling. The multimedia control unit 11 in the third modification also has a travel forcing function that prohibits execution of some of the processes provided by various function providers when the vehicle is traveling. The configuration and operation of the multimedia control unit 11 in such an aspect will be described.

  In the third modification, a storage area such as a ROM of the multimedia control unit 11 stores a list of processes to be subjected to the travel forcing function, an instruction operation (button ID, etc.) for executing the process, and an image ID. It is assumed that The image ID here is an identification number unique to each image generated by the MM side display control unit F5 based on display output data from each function provider.

  The MM side operation reception unit F6 can determine whether or not the user's instruction operation is an instruction operation that is a target of the travel forcing function by referring to the list. Further, the MM-side display control unit F5 can determine whether the operation-corresponding image currently displayed temporarily is an image corresponding to the instruction operation that is the target of the travel forcing function.

  Moreover, the multimedia control part 11 in the modification 3 is provided with the driving | running | working state determination part F9 in addition to the above-mentioned various functional blocks (F1-F8), as shown in FIG. The traveling state determination unit F9 determines whether or not the vehicle is traveling based on the detection result of an in-vehicle sensor (not shown).

  When the traveling state determination unit F9 determines that the vehicle is stopped, when the shift position is the parking position or when the parking brake is on, the vehicle speed is 0 km / h (or a predetermined value). Or less). Further, when the traveling state determination unit F9 determines that the vehicle is traveling, the vehicle speed is greater than a predetermined threshold (for example, 0 km / h), or the shift position is other than the parking position. For example, the position may be set. Alternatively, it may be determined that the vehicle is traveling when the steering angle is changing.

  The traveling state determination unit F9 may determine whether or not the vehicle is traveling by appropriately combining the conditions exemplified here. Further, it may be determined whether or not the vehicle is traveling by a known method other than those exemplified here. The traveling state determination unit F9 detects that the vehicle has started to travel based on the transition from the stopped state to the traveling state. The traveling state determination unit F9 corresponds to the traveling determination unit described in the claims.

  When the driving state determination unit F9 detects that the vehicle has started to travel, when the operation-corresponding image corresponding to the instruction operation targeted for the traveling forcing function is displayed on the center display 12, The MM side display control unit F5 cancels the display of the image even before the holding time has elapsed.

  In addition, not only when the operation corresponding image corresponding to the instruction operation targeted for the travel forcing function is displayed, the subsequent instruction operation that can be input by the user in the currently displayed operation corresponding image is the Even in the case of the target, the display of the operation corresponding image may be canceled.

<Modification 4>
In the above-described third modification, the aspect in which the display state of the operation corresponding image corresponding to the instruction operation that is the target of the travel forcing function is exemplified in the multimedia unit 10, but the meter unit 20 performs the same processing. You may let them.

  In other words, the meter control unit 21 also has a function corresponding to the traveling state determination unit F9, and an operation corresponding to the instruction operation that is the target of the traveling forcing function when it is detected that the vehicle has started traveling by the function. When the corresponding image is displayed on the meter display 23, the meter-side display control unit G1 cancels the display of the image even before the holding time has elapsed. According to such an aspect, the visibility of vehicle information and the like can be improved.

<Modification 5>
In the above, an image whose display is canceled as the holding time elapses may be temporarily saved in a RAM or the like and redisplayed based on a user operation. According to such an aspect, the user can continue the instruction operation subsequent to the operation corresponding image that is once not displayed.

  For example, for an image whose display is canceled with the lapse of the holding time, an icon image for calling the image is displayed at the corner of each display. Then, when the icon image is selected by the user, the operation corresponding image corresponding to the selected icon image may be displayed again. This modification 5 may be realized with the aid of the technique of Patent Document 1, for example.

<Modification 6>
In the above-described embodiment, the multimedia control unit 11 exemplifies a mode in which an instruction operation by a user with respect to various function providers is received via the multimedia operation unit 14 and the steering switch 30 mounted on the vehicle. Not exclusively. For example, the multimedia control unit 11 may accept an instruction operation by a user for various function providers via an external operation device such as the mobile terminal 40. That is, the user may execute instructions for various function providers using an input device or a voice recognition function provided in the mobile terminal 40.

  For such an instruction operation by the user via the external operation device, the same processing as the instruction operation by the user via the multimedia operation unit 14 may be performed.
