In this embodiment, the control unit 4 in the head-up display 2 switches the guide image to be displayed according to the traveling state of the vehicle. That is, the control unit 4 switches and displays a guide image suitable for the traveling state of the vehicle. Specifically, the control unit 4 determines whether the vehicle is at a predetermined speed or higher when the vehicle is stopped and when the vehicle is traveling at a speed lower than a predetermined speed (hereinafter referred to as “low speed driving” as appropriate). The guide image to be displayed is switched when the vehicle is traveling (hereinafter referred to as “at high speed” as appropriate). Specifically, the control unit 4 displays the display mode for the guide point information regarding the guide point where the vehicle is scheduled to pass and the route information indicating the route to the destination when the vehicle is stopped, when driving at a low speed, and when driving at a high speed. Change. In addition, the control unit 4 switches between displaying and hiding predetermined information when the vehicle is stopped, when traveling at a low speed, and when traveling at a high speed. For example, the control unit 4 displays a POI (Point Of Interest) existing on the route only when traveling at a low speed, and does not display such a POI when stopping or traveling at a high speed. In addition, for example, the control unit 4 displays traffic information only when traveling at a high speed, and does not display traffic information when stopped or traveling at a low speed.

The route information, guide point information, POI information, and traffic information described above are information included in the guide information. The CPU 22 in the navigation device 1 stores the map data and vehicle information stored in the data storage unit 36. It is generated based on the current position. The route information is information relating to a route from the departure point to the destination (may include a waypoint). The guide point information is information related to a guide point (such as an intersection) existing on such a route. For example, the guide point information is information including at least one or more of the name of the guide point, the direction to travel at the guide point (such as left turn or right turn), and the distance to the guide point. The POI indicates a facility or place registered as map data, or a specific facility or place designated by the user among these. The traffic information is traffic jam information, for example. The traffic jam information is information including a section of a road in which the traffic jam occurs and the degree of the traffic jam (for example, any one of “traffic jam”, “crowded”, and “smooth”). Such traffic information is received by the communication device 38 in the navigation device 1 communicating with a VICS (Vehicle Information and Communication System) center. “VICS” is a registered trademark (hereinafter the same).

Further, the CPU 22 in the navigation device 1 determines whether the vehicle is stopped, traveling at a low speed, or traveling at a high speed. For example, the CPU 22 makes the determination based on the vehicle speed pulse measured by the distance sensor 13 of the autonomous positioning device 10 and supplies the determination result to the control unit 4 in the head-up display 2.

Hereinafter, specific display examples by the control unit 4 in the head-up display 2 will be presented with reference to FIGS.

displays POI images

230 a and 230 b indicating POIs existing on the route corresponding to the route image 210 on the route image 210. The POI image 230a shows a gas station, and the POI image 230b shows a coffee shop. In this case, the control unit 4 changes the display size of the POI image 230 according to the distance from the current position to the POI position. Specifically, the control unit 4 increases the display size of the POI image 230 as the distance is shorter. The content of information corresponding to the POI, the position of the POI, and the like are stored as map data in the data storage unit 36 of the navigation device 1.

As described above with reference to FIG. 5, according to the present embodiment, information suitable for presentation during low-speed travel can be displayed in a mode suitable for low-speed travel. Therefore, when the vehicle is traveling at a low speed, the driver can appropriately grasp the route information, the guide point information, and the POI information. Specifically, the driver is made aware of route information within a relatively close range of the current position, guidance point information about a guidance point where the vehicle is scheduled to pass next, and information about POI existing on the route. be able to.

Next, FIG. 6 shows an example of a guidance image displayed when the vehicle is traveling at high speed. FIG. 6 also shows an example of a guidance image that the driver visually recognizes through the combiner 9.

As shown in FIG. 6, when the vehicle is traveling at a high speed (running at a predetermined speed or higher), the control unit 4 has a route image 310 corresponding to the route information and a guidance point image corresponding to the guidance point information. 320, concentric

distance display images

330a and 330b (330) indicating the same distance from the current position, and a direction display image 340 indicating a direction based on the current position are displayed as the guide images.

Specifically, the control unit 4 as the route image 310 shows a belt-like image that shows a route within the second range wider than the first range from the current position of the vehicle in the route to the destination. Is displayed. In this case, the control unit 4 displays a route image 310 indicating a route within a wide range that is relatively far from the current position.

Further, the control unit 4 displays a guide point image 320 indicating guide point information regarding a guide point one point ahead from the current position (that is, a guide point where the vehicle is scheduled to pass next). Specifically, the control unit 4 displays a guide point image 320 including an arrow image 320a indicating that a left turn should be made at the guide point and an image 320b indicating a distance from the current position to the guide point.

The control unit 4 also displays concentric

distance display images

330a and 330b connecting positions that are equidistant from the current position. The

distance display images

330a and 330b indicate distance intervals from the current position, and are drawn at equal intervals from the current position (“2.5 km” in the example illustrated in FIG. 6). Specifically, the distance display image 330a indicates a position “2.5 km” from the current position, and the distance display image 330b indicates a position “5 km” from the current position. In the above description, concentric circles are used to express the distance display image 330, but strictly speaking, the distance display image 330 is an image of a concentric arc. However, a concentric circle image in a strict sense may be used as the distance display image 330 instead of the concentric arc image.

In addition, the control unit 4 displays an arc-shaped direction display image 340 that indicates the direction when viewed from the same viewpoint as the route image 310 with the current position as the center, outside the distance display image 330b. . The position of “N” in the direction display image 340 indicates a north direction with the current position as a base point. Further, the lower end position of the direction display image 340 corresponds to the traveling direction of the vehicle. That is, the control unit 4 fixes the position corresponding to the traveling direction of the vehicle on the direction display image 340 to the lower end position. Further, the control unit 4 rotates the direction display image 340 according to the direction of the vehicle, so that an accurate direction is always displayed with respect to the current position. Instead of displaying the direction display image 340 outside the distance display image 330b, the direction display image 340 may be displayed inside the distance display image 330a.

Furthermore, the control unit 4 displays the traffic

jam display images

350a, 350b, 350c (350) indicating the traffic jam information on the route image 310 in an overlapping manner. That is, the control unit 4 displays a location where traffic congestion has occurred on the route image 310 with a predetermined color. Specifically, the traffic

jam display images

350a and 350c indicate that the degree of traffic jam is “traffic jam”, and for example, red is applied. Further, the traffic jam display image 350b indicates that the degree of traffic jam is “congested”, and orange, for example, is applied. The control unit 4 acquires the traffic information (information including the road section where the traffic jam occurs and the level of traffic jam) received by the communication device 38 in the navigation device 1 communicating with the VICS center. Such a traffic jam display image 350 is generated. In addition to the above-described traffic jam information, road regulation information (information indicating lane regulation, traffic closure, traffic regulation, etc.) may be displayed on the route image 310 as traffic information.

As described above with reference to FIG. 6, according to the present embodiment, information suitable for presentation at high speed travel can be displayed in a mode suitable for high speed travel. Therefore, when the vehicle is traveling at high speed, the driver can appropriately grasp the route information, the guide point information, and the traffic information. Specifically, the driver can be made aware of route information over a wide range, guidance point information regarding a guidance point where a vehicle is scheduled to pass next, and traffic information on the route. In this case, by displaying the distance display image 330 and the direction display image 340 together, the driver can accurately grasp the route information and the traffic information.

It should be noted that when the vehicle is traveling at high speed, POI information may be further displayed in the same manner as during low-speed traveling. In that case, POI information may be displayed on any of the route image 310, the distance display image 330, and the direction display image 340.
