6D are views showing a display screen of the display 18 displaying oncoming vehicle information when the vehicle 21 makes a right turn, and FIG.
(A)-(c) is a figure which shows the display screen of the display 18 which displays the information of a forward crossing pedestrian.

First, in step S01 shown in FIG. 4, when the vehicle 21 enters the communication area of the information transmitting device 22, for example, as event information, for example, road regulation such as road works and width reduction, pedestrians and Information such as stopped vehicles, obstacles, falling objects, broken cars, accidents, traffic congestion, and other events, as well as information on road conditions caused by natural conditions including weather, such as rainfall and snowfall, is received. Next, in step S02, for example, as shown in FIG. 5 (a) or FIG. 6 (a), from a state where a navigation map used for route guidance or the like is displayed on the display screen of the display 18, for example. Then, a pop-up display screen P is generated and the display on the display 18 is switched.

Next, in step S03, on the pop-up display screen P generated on the display 18, the current position V of the vehicle 21 and the travel route information Q (for example, at a front intersection) are displayed on an enlarged map of the position related to the event information. 5A, etc., and the content R of the event information (for example, “Caution! Right turn oncoming vehicle” shown in FIG. 5A or “Caution! Forward pedestrian” shown in FIG. 6A). ) Are displayed by, for example, character data or the like.

Next, in step S04, the vehicle 2
1 (for example, “100 m” shown in FIG. 5A or FIG. 6A).
First). Next, in step S05, a simplified figure (for example, FIG. 5 ()) for an event (for example, an oncoming vehicle in FIGS. 5 (a) to 5 (c) or a pedestrian crossing in FIGS. 6 (a) and 6 (b)). Simplified figures A1, A2, A3 of oncoming vehicle in a) to (c) or FIG.
(A), (b) simplified pedestrian figure B1,
B2 etc.) are displayed.

Here, the vehicle 21 is positioned with respect to the event occurrence position.
As the vehicle approaches, the current position V of the vehicle 21 is displaced on the map displayed on the pop-up display screen P, and the display of the distance information S from the vehicle 21 to the position where the event has occurred is changed. Enlarged image is displayed. For example, as shown in FIGS. 5A to 5C, the display of the distance information S to the oncoming vehicle including one four-wheeled vehicle and two-wheeled vehicle is indicated by “100 m ahead”, “60 m ahead”, and “4 m”.
0m ahead ", the simplified graphic A1 of the oncoming vehicle is changed to the simplified graphic A2 larger than the simplified graphic A1, and further the simplified graphic A larger than the simplified graphic A2.
Change to 3 sequentially. In addition, for example, FIG.
As shown in (b), the display of the distance information S to the pedestrian who is traversing ahead is sequentially changed to “60 m ahead” and “40 m ahead”. ,
It is changed to a simplified graphic B2 larger than the simplified graphic B1.

Then, in step S06, as shown in FIG. 5D or FIG. 6C, for example, the pop-up display screen P is displayed when the event has disappeared or the vehicle 21 has passed the event occurrence position. After ending, for example, a navigation map indicating the current position V of the vehicle 21 is displayed, and a series of processing ends.

Hereinafter, an example of the type of display on the pop-up display screen P when the vehicle 21 makes a right turn at an intersection in front will be described with reference to the accompanying drawings. FIGS. 7A to 7D and FIGS.
(D) is a diagram showing a pop-up display screen P for displaying oncoming vehicle information at the time of a right turn, and FIGS. 9 (a) to 9 (d) are diagrams showing pop-up display screens P for displaying crossing pedestrian information ahead. is there.

For example, as shown in FIGS.
When there is one four-wheeled vehicle as the oncoming vehicle, the distance information S from the vehicle 21 to the four-wheeled vehicle (for example, “10
0 m ahead, 60 m ahead, 40 m ahead, etc.).
1, C2 and C3 are displayed. In addition, for example, FIG.
As shown in (d), when one two-wheeled vehicle exists as the oncoming vehicle, the distance from the vehicle 21 to the two-wheeled vehicle (for example, “100 m ahead”, “60 m ahead”, “40 m”)
A plurality of (for example, three types) simplified graphics D1, D2, and D3 having different sizes are displayed in accordance with the “destination” and the like. 9A to 9D, when there is a pedestrian crossing in front of the vehicle, the distance from the vehicle 21 to the pedestrian (for example, “100 m ahead”, “60 m ahead”). ",
A plurality (for example, three types) of simplified figures B1, B2, and B3 having different sizes according to “40 m ahead” or the like are displayed.

As described above, according to the in-vehicle display device 10 of the present embodiment, a simplified graphic of an event is displayed for the event information received from the outside of the vehicle 21.
The attention of the occupant can be easily urged, and the contents of the event information can be quickly and reliably grasped. Moreover, since the simplified graphic is enlarged and displayed as the vehicle 21 approaches the event occurrence position, in addition to the event occurrence,
The occupant can easily recognize the degree of approach to the event, and it is possible to prevent a delay in responding to the event and to respond at an appropriate timing.

In the present embodiment, when the event information is received, the display on the display 18 is changed from the display of the navigation map to the pop-up display screen P.
, But is not limited to this. For example, the display 18 according to a modification of the present embodiment shown in FIG.
When the event information is received, the display screen of the display 18 is divided into a plurality of screens (for example, two screens) as shown in FIG. A pop-up display screen P may be generated.

Further, in synchronization with the display of the event information on the pop-up display screen P, the content R of the event information (for example, as shown in the liquid crystal display screen of the display unit 16 shown in FIG. “Intersection”), distance information S (for example, “60 m ahead”) to the event occurrence position, and simplified graphic F1 indicating the event may be displayed on display unit 16.

In this case, for example, as shown in the liquid crystal display screen of the display unit 16 shown in FIG. 11B, the display unit 16 displays a figure F2 or character data T (for example, easily visible) as auxiliary information relating to an event. Only the “stop” as the alarm information is displayed, and on the pop-up display screen P of the display 18, as the detailed information on the event, the occurrence position of the event (for example, the position of the simplified graphic F3 on the map of the pop-up display screen P) ) And distance information S from the vehicle 21
(Eg, “60 m ahead”) and information such as the content R of the event information (eg, “stop at an intersection”) may be displayed.
