As shown in FIGS. 6 and 7, the management information D3 includes an event number, a user operation, and display areas (I) to (IV) (in FIG. 7, three display areas (I) to (III)). This is information that correlates display contents. Here, the event number is information (event specifying information) for managing an interrupt generated by the operation of the operation unit 14.
In FIGS. 6 and 7, information (a) to (l) indicated by lowercase letters indicates display image information previously associated with each value, and numbers (1) to (3) indicate the numbers. “−” Indicates that no screen transition is performed.

  As a specific example, in the management information D3 shown in FIG. 6, the display image information (a) is displayed in the display area (I) at the time of activation (when the event of event number 17 occurs), and displayed in the display area (II). Display image information (d), display image information (f) in display area (III), display image information (h) in display area (IV), and then event number (2) It is described that when the event occurs, the display area (I) is switched to the display image information (b), and the screens of the display areas (II) to (IV) are not changed. After that, when an event with event number (4) occurs, switching to template number (2) is described.

On the other hand, in the management information D3 shown in FIG. 7, the display image information (i) is displayed in the display area (I) at the time of activation (when the event of event number 14 occurs), and the display image information (k) is displayed in the display area (II). ) And display the display image information (l) in the display area (III). After that, when the event of the event number (2) occurs, the display area (I) is switched to the display image information (j). The display areas (II) and (III) are described not to transition to the screen. After that, when an event of event number (5) occurs, switching to template number (1) is described.
Thus, depending on the event, the display of all display areas is not switched, but only a part of the display areas is switched, so that the amount of display image information required for switching can be reduced.

In the portable terminal 21, a use template management table D4 shown in FIG. 8A and a display state management table D5 shown in FIG. 8B are stored in the storage unit 26 or the RAM.
As shown in FIG. 8A, the use template management table D4 is information describing the number of the display template being used. Accordingly, the mobile terminal 21 can grasp the display template being used by the in-vehicle device 11.
As shown in FIG. 8B, the display state management table D5 is information describing the display states (information indicating display image information) of the display areas (I) to (IV). Thereby, the mobile terminal 21 can grasp the information being displayed in each display area of the in-vehicle device 11.

Next, the operation during the cooperation process will be described using the configuration shown in FIG. 3 and FIG.
FIG. 9 is a diagram showing the flow of the cooperation processing, and FIG. 10 shows the continuation.
First, as illustrated in FIG. 9, in the in-vehicle device 11, when the start process is started, the event number transmission unit 51 (FIG. 3) specifies an event number (for identifying an event generated by the operation of the operation unit 14 (FIG. 2)). Event specifying information) is wirelessly transmitted to the portable terminal 21 via the transmission control unit 52 and the wireless communication unit 17 (step S1).

In the portable terminal 21, when the event number receiving unit 71 (FIG. 4) receives the event number wirelessly transmitted from the in-vehicle device 11 via the wireless communication unit 27 and the reception control unit 72, the template number determination unit 73 (FIG. 4). ) Refers to the management information D3 (FIG. 6) based on the event number and the use template management table D4 (FIG. 8A), and acquires the corresponding template number (step S2).
At the first activation, the use template management table D4 is set to a default value (template number (1)). For this reason, template number (1) is acquired in step S2.
In the portable terminal 21, the template number transmission unit 74 (FIG. 4) wirelessly transmits the acquired template number (template designation information) to the portable terminal 21 via the transmission control unit 75 and the wireless communication unit 27 (step). S3).

In the in-vehicle device 11, the template number receiving unit 53 (FIG. 3) receives the template number wirelessly transmitted from the mobile terminal 21 via the wireless communication unit 17 and the reception control unit 54 (FIG. 3), and the template presence / absence determining unit 55 (FIG. 3) determines whether or not the received template number exists (step S4).
In this case, the in-vehicle device 11 determines whether or not a display template corresponding to the received template number is stored in the storage unit 16. Then, when the display template does not exist, it is determined that the template number does not exist, and when the display template exists, it is determined that the template number exists.

When the template number does not exist, in the in-vehicle device 11, the display template request transmission unit 56 (FIG. 3) makes a request for the template to the portable terminal 21 via the transmission control unit 52 and the wireless communication unit 17 ( Step S5). In this case, in the portable terminal 21, when the display template request receiving unit 76 (FIG. 4) receives the request, the display template transmitting unit 77 (FIG. 4) sends the requested display template information D1 to the in-vehicle device 11. Wireless transmission is performed (step S6 in FIG. 8).
Thus, after the display template information D1 is received by the display template receiving unit 57 of the in-vehicle device 11 and stored in the storage unit 16, the display unit 13 draws a display template corresponding to the template number on the screen 11X. The process to perform is executed (step S7).

  On the other hand, when a template number exists, it transfers to step S7 and the process which draws a display template on the screen 11X is performed in the vehicle-mounted apparatus 11. FIG. The above steps S2 to S7 are “template determination process + template drawing process”.

  Next, in the portable terminal 21, the display state acquisition unit 78 (FIG. 4) acquires each display area (display areas (I) to (IV) of the template number (1)) from the display state management table D5 (step) S8). In addition, the display image number determination unit 79 refers to the management information D3 based on the event number and the display state management table D5, and displays the display image information ((a) to (f) in FIG. 6) for display or screen transition. Such information is acquired (step S9). In this case, the use template acquisition unit 80 specifies the display template being used by referring to the display state management table D5.

When the information acquired in step S9 is “− (no screen transition)” (step S10; YES), the process proceeds to step S8 to confirm the next display area.
On the other hand, when the information acquired in step S9 is “(transition to another template)” (step S11; YES), the usage template management table D4 (FIG. 8A) is updated (step S12), and the event number 17 Is set (step S13), and the display state of all display areas is set to no display (step S14). Then, the process proceeds to step S2.

When the information acquired in step S9 is “display image” (step S15; YES), the display image acquisition unit 81 (FIG. 4) acquires display image information corresponding to the display image (step S15). Here, the display image information is information held in the mobile terminal 21 (in the application program) (for example, an operation image corresponding to a soft key), or information acquired from the server by the mobile terminal 21 (for example, on the Internet). Browsing image).
At this time, the display image acquisition unit 81 also performs data conversion processing for converting the display image information into data in accordance with the screen size (aspect ratio and resolution), the number of pixels (density), and the number of colors of the display area of the display destination. . That is, the display image acquisition unit 81 also functions as a conversion processing unit that converts the display image information into information matched to the display area.

  Next, in the mobile terminal 21, the display area number transmission unit 82 (FIG. 4) wirelessly transmits the display area number (display destination designation information) indicating the display destination to the in-vehicle device 11, and the display image transmission unit 83 displays the display area number. Display image information matched to the area is wirelessly transmitted to the in-vehicle device 11 (step S16).

Subsequently, in the in-vehicle device 11, when the display area number receiving unit 58 (FIG. 3) receives the display area number and the display image receiving unit 59 receives the display image information, the display area number is received in the display area corresponding to the display area number. Then, an image corresponding to the received display image information is displayed (step S17).
Thereafter, in the in-vehicle device 11, the drawing result is determined by the display drawing determination unit 60, and the drawing result (information specifying the drawn display area number and the drawn display image) is sent to the portable terminal 21 by the drawing result transmission unit 61. Radio transmission is performed (step S18).

In the portable terminal 21, the drawing result receiving unit 84 (FIG. 4) determines the received drawing result, and determines whether or not the drawing is performed as specified (consistency with the transmission result in step S16) (step S19). ). If the drawing result is OK, the display state management table D5 (FIG. 8B) is updated to update the display area of the display area (step S20), and step S8 is performed to display the next display area. Migrate to
On the other hand, if the drawing result is NO, the process proceeds to step S8 without performing step S20. In this way, the processing from step S8 to step S20 is repeated by the number of display areas. The above steps S8 to S20 are “drawing image determination process on display area + display area drawing process”.

In the in-vehicle device 11, the interrupt process determination unit 50 (FIG. 3) monitors the operation of the operation unit 14 (FIG. 2), and performs an interrupt process when an operation is detected.
