FIG. 5A is different from the above-described embodiment in that the remaining vehicle external information is displayed when the engine speed exceeds the threshold and the bar graph display enlarged image p3 is displayed on the interrupt overlap display portion P3. In the part P2, the map information image p2 is displayed as a reduced map information image p21 reduced. Therefore, in the vehicle external information display part P2 which is narrowed as a display area, the bar graph display enlarged image p3 occupies a part of the vehicle external information display part P2, and the aspect ratio of the display area of the vehicle external information display part P2 changes. Therefore, by displaying the reduced map information image p21 obtained by reducing the original map information image p2 as a whole, it is possible to grasp the entire map information. Therefore, the convenience of the vehicle information providing apparatus is improved. And it becomes possible to improve visibility.

Further, FIG. 5B is different from the above-described embodiment in that the engine speed exceeds the threshold value and the bar graph display enlarged image p3 is displayed on the interrupt overlap display portion P3. In the information display part P2, the map information image p2 is displayed as an enlarged map information image p22. Accordingly, by displaying the enlarged map information image p22 in the vehicle external information display portion P2 that is to be narrowed as a display area, it becomes possible to enlarge and change the necessary portion of the map information. The convenience and visibility of the vehicle information providing apparatus can be improved.

Further, FIG. 5C differs from the above-described embodiment in that when the bar graph interrupt display image of the engine speed is displayed on the interrupt overlap display portion P3, it is displayed as the transparent image p32. . Therefore, by displaying the transparent image p32 that enables the map information image p2 displayed on the vehicle external information display part P2 to be visually recognized, the transparent image p32 that displays the engine speed in a bar club shape together with the map information image p2 is visually recognized. Since both information can be viewed at the same time, the convenience and visibility of the vehicle information providing apparatus can be improved. 5C will be described in detail. If the first control unit 202 determines that the engine speed is 6000 r / min or more, the first control unit 202 displays the transparent image p32 on the interrupt overlap display P3. However, the transmission image p32 from the threshold value of 6000 r / min or more to the actual measurement value is displayed in a color tone different from that of the other Barclav display areas.

  Note that the interrupt display image p3 of the above-described embodiment has been described as an example of displaying the engine speed as a bar graph, but can be changed to various forms, for example, displaying a message or an icon. The present invention is not limited to this embodiment.

  Needless to say, the interrupt overlap display portion P3 can be changed to various forms as long as the region overlaps the vehicle external information display portion P2.

  The present invention relates to a vehicle information providing apparatus that provides various types of information using a vehicle-mounted display and an external device. For example, the display apparatus is mounted on a vehicle including an automobile, a motorcycle, an agricultural machine, or a construction machine. And is particularly suitable for a display device using a small vehicle-mounted display.
