  With reference to FIG. 6, the processing of the display content of the display area of the navigation system in the meter 50 will be described. This process is included in the navigation program 21p and is repeatedly executed together with other programs. First, meter display color data (that is, meter color information) displayed on the meter 50 is acquired from the meter ECU 40 (S1).

  Next, the navigation display content to be displayed on the display 54 of the meter 50 is determined (S2). This is the same as determining the display content of the display device 10 by the navigation device 100, and is a well-known function in the navigation device 100, such as displaying the current position of the vehicle with a road map superimposed thereon. I will omit the explanation.

  When the display content to be displayed on the display unit 54 is determined, the drawing unit 87 processes an adjacent region to the display region of the meter 50 according to the meter color information from the display content and the previously acquired display color of the meter 50. Then, a drawing process for creating navigation drawing data (details will be described later) is performed (S3).

  When the navigation drawing data is created, the drawing data is sent to the meter ECU 40 via the in-vehicle LAN 27. The meter ECU 40 sends the meter display drawing data and the navigation drawing data created by the drawing unit 43 in the meter control program 41p to the display 54, and the display 54 displays these drawing data (S4).

  A drawing process corresponding to step S3 in FIG. 6 will be described with reference to FIG. First, the type (edge type) or color of navigation display data in an area adjacent to the display area of the meter 50 is acquired (S11).

  Next, a processing method corresponding to the acquired edge type or color is determined (S12). The processing method is such that navigation display data in an area adjacent to the display area of the meter 50 is matched with the display color of the display area of the meter 50 for each map data, such as blurring, gradation, tone down (luminance change), etc. There is a way.

  As shown in FIG. 5, display colors are usually defined according to the type of map data. In addition, the range for processing the map data from the boundary line with the display area of the meter 50 is defined by the number of dots of the display 54. These data are stored as table data in a form included in the map data 21m of the HDD 21 and the like. The range of the processing dot number defined in this table data is processed. Similarly, display designs such as display colors and sizes are processed for character data such as place names and facility names.

  Next, the processing method of the adjacent map data is acquired (S13), and when the processing amount of the adjacent map data, that is, the number of processed dots is larger by referring to the table data (S14: YES) The processing amount of the map data is matched with the processing amount of the adjacent map data (S15). On the other hand, when the processing amount of the adjacent map data, that is, the number of processing dots is smaller (S14: NO), the processing amount of the adjacent map data is matched with the processing amount of the local map data (S17).

  FIG. 9 shows an example of processing. 63 is a display area of the navigation system and 64 is a display area of the meter. For each type of map data displayed in the display area 63 of the navigation system, the processing area is determined as processing areas A and B, for example, with reference to the table data. At this time, when the length from the boundary 65 of the processing area A (that is, the number of processing dots) is different from the number of processing dots in the processing area B, the length is adjusted to the one with the larger number of processing dots. Therefore, the number of processing dots in the processing area A and processing area B is finally the same.

  Then, the processing from steps S12 to S16 is repeated until the entire drawing processing content is determined (S16: YES).

  FIG. 8 shows a display example on the meter 50. In the example of FIG. 8, the entire surface of the display 54 is a liquid crystal display, including a water temperature display area 61, a vehicle speed display area 62, a display area 63 such as a travel distance / shift position, an engine speed display area 64, and a fuel gauge display. An area 65, a navigation system display area 66, and the like are included.

  In the example of FIG. 8, the display area 66 of the navigation system is not a rectangular shape that is conventionally used, but is a shape that enters the unused areas of the vehicle speed display area 62 and the engine speed display area 64 and is not necessarily rectangular. Need not be. With this configuration, the display area of the panel 54a can be used effectively, and the display area 66 of the navigation system can be widened. Further, the color of navigation data such as maps displayed in the unused area of the vehicle speed display area 62 and the engine speed display area 64 is processed so as to match the display color of each display area. Does not occur.

  In the display area 66 of the navigation system, the upper, lower, left and right peripheral parts are the background color of the meter display 54, the display color of the display area 63 such as the travel distance / shift position, the display color of the vehicle speed display area 62, and the engine speed display, respectively. The display design is processed so as to match the display color of the region 64.

(Modification 1)
In the above embodiment, the display area 66 of the navigation system is processed according to the display color on the meter 50. Conversely, the display area of the meter (for example, 62, 64) according to the display color of the navigation system. It is good also as a form which processes. In this case, the processing process of FIG. 6 and the drawing process of FIG. 7 are executed by being included in the meter control program 41p of the meter ECU 40, and the drawing unit 43 creates drawing data. In the example of FIG. 9, the processing area C is a processing target.

  In this embodiment, the meter color information acquisition process in step S1 in the above embodiment is a navigation color information acquisition process for acquiring drawing data (that is, color information) of the navigation system from the navigation device 100. Further, data corresponding to the table data in FIG. 5 is stored in the ROM 41b or a flash memory (not shown). For example, the number of processed dots is defined for the background, memory, characters, etc. of the meter 50.

Both areas to be processed are processed. As shown in FIG. 11, the drawing ECU 60 has the same configuration as the meter ECU 40, and is connected to the control unit 61 and the control unit 61 via an I / O 62 that is an input / output circuit. F64 and flash memory 65 are included.
