When an image is displayed so as to overlap the scenery in front of the moving object or a photographed image of the scenery, the display of the driver is obstructed by the display, so it is necessary to avoid unnecessary display. The head-up display described in Patent Document 1 uniformly displays the entire route image corresponding to the guide route included in the forward scenery. However, in this case, the display may be complicated depending on the traveling situation, and the field of view may be unnecessarily blocked by the route image. On the other hand, even a part of the guide route included in the forward scenery, there is a part that is less necessary for the driver to recognize immediately.

The present invention has been made to solve the above-described problems, and mainly provides a display device capable of displaying a route image suitably without unnecessarily blocking the driver's field of view. Objective.

The route image corresponding to the route within the predetermined range from the current position in the guide route and the route image corresponding to the route outside the predetermined range of the guide route are displayed in different modes. Display control means is provided.

The above display device displays a route image indicating the guide route to the destination in association with the guide route so as to overlap the scenery seen in front of the moving object or the image of the scenery. At this time, the display device includes a route image (also referred to as “first route image”) corresponding to a route within a predetermined range from the current position in the guide route, and a route outside the above-described predetermined range of the guide route. And the route image corresponding to (also referred to as “second route image”).

In general, when an image is displayed so as to overlap a frontal scene of a moving body or a live-action image obtained by capturing the scene, the display of the driver is blocked by the display, and thus unnecessary display must be avoided. Therefore, even in the case of displaying a route image, it is preferable to use the same display mode for a portion that the driver needs to recognize immediately and a portion that the driver does not need to recognize immediately. Absent. Considering the above, the display device described above changes the display mode between the first route image and the second route image.

[Configuration of head-up display]
FIG. 3 is a schematic configuration diagram of the head-up display 2. As shown in FIG. 3, the head-up display 2 according to the present embodiment includes a light source unit 4 and a combiner 9. The vehicle Ve includes a front window 25, a ceiling portion 27, a hood 28, a dashboard 29, and the like. It is attached.

The light source unit 4 is installed on the ceiling 27 in the passenger compartment via the

support members

5a and 5b, and emits light constituting an image indicating information for assisting driving toward the combiner 9. Specifically, the light source unit 4 generates an original image (real image) of the display image in the light source unit 4, and emits light constituting the image to the combiner 9, thereby allowing the driver to pass through the combiner 9. The virtual image “Iv” is visually recognized. The configuration of the light source unit 4 will be described in the section [Configuration of the light source unit].

The combiner 9 projects the display image emitted from the light source unit 4 and reflects the display image to the driver's eye point “Pe” to display the display image as a virtual image Iv. And the combiner 9 has the support shaft part 8 installed in the ceiling part 27, and rotates the support shaft part 8 as a spindle. The support shaft portion 8 is installed, for example, in the vicinity of the ceiling portion 27 in the vicinity of the upper end of the front window 25, in other words, the position where a sun visor (not shown) for the driver is installed. The support shaft portion 8 may be installed instead of the above-described sun visor. The light source unit 4 and the combiner 9 are examples of the “display unit” in the present invention.

[Configuration of light source unit]
FIG. 4 is a diagram schematically showing the configuration of the light source unit 4. As shown in FIG. 4, the light source unit 4 includes a light source 62, a communication unit 64, and a control unit 65.

The control unit 65 includes a CPU, a ROM that stores a control program executed by the CPU, data, and the like, and a RAM that sequentially reads and writes various data as a work memory when the CPU operates. Control. The controller 65 is an example of the “display control means” and “computer” in the present invention.

In particular, in the present embodiment, the control unit 65 causes the light source 62 to emit light that forms a route image indicating the guide route based on the information on the guide route received from the navigation device 1, so that the driver's front landscape is displayed. A route image indicating the guidance route is displayed on the combiner 9 so as to overlap.

[Display method of route image]
Next, a route image display method executed by the control unit 65 will be described. Schematically, the control unit 65 includes a route image corresponding to a route (also referred to as “first route portion R1”) within a predetermined distance along the guide route from the current position in the guide route, and the first route. The display mode is changed depending on the route image corresponding to the guide route other than the part R1 (also referred to as “second route part R2”). Specifically, the control unit 65 sets the portion of the route image corresponding to the second route portion R2 in a display mode that is less conspicuous than the portion of the route image corresponding to the first route portion R1. Thereby, it is suitably suppressed that the display of the route image is complicated during the U-turn or when traveling on the loop road.

Hereinafter, the above-mentioned predetermined distance for separating the first path part R1 and the second path part R2 is also referred to as “distance Lth”. Further, the route image corresponding to the first route portion R1 is also referred to as “first route image Im1”, and the route image corresponding to the second route portion R2 is also referred to as “second route image Im2.”

(1) Processing Flow FIG. 5 is a flowchart showing a route image display process executed by the control unit 65. The control unit 65 executes the process of the flowchart shown in FIG. 5 every time the navigation device 1 executes the route search process.

First, the control unit 65 acquires information on the guide route determined by the route search process from the navigation device 1 (step S101). Specifically, first, when a destination is input from the input device 60, the system controller 20 of the navigation device 1 performs a route search process from the current position measured by the GPS receiver 18 to the destination, and provides guidance. A route that is a candidate for the route is displayed on the display unit 40. Then, the system controller 20 sets the route selected by the input to the input device 60 by the user as the guide route that the vehicle Ve is scheduled to travel, and transmits information on the guide route to the head-up display 2 by the communication device 38. . And the control part 65 receives the information of the above-mentioned guidance route via the communication part 64. FIG.

Next, the control unit 65 has a first route portion R1 that is within the distance Lth along the guide route from the current position, and a second route portion R2 that is separated from the current position by the distance Lth along the guide route. (Step S102). Here, the distance Lth is, for example, the portion of the guide route that the driver should recognize immediately during driving is the first route portion R1, and the portion of the guide route that the driver does not need to recognize immediately during driving is the first route portion R1. Based on an experiment or the like so as to be the second path portion R2, it is stored in the memory or the like of the control unit 65. The controller 65 divides the guide route into the first route portion R1 and the second route portion R2 by referring to the distance Lth described above based on the current position information received from the navigation device 1.

Next, the control unit 65 displays on the combiner 9 such that the second route image Im2 indicating the second route portion R2 is less noticeable than the first route image Im1 indicating the first route portion R1 ( Step S103). In this case, the control unit 65 causes the light source 62 to emit light constituting these route images toward the combiner 9. As described above, the control unit 65 suitably suppresses the complication of the display by making the second route image Im2 showing the second route unit R2 that does not need to be recognized immediately by the driver inconspicuous. be able to.

Here, a supplementary description will be given of the display mode of the first route image Im1 and the second route image Im2. In the first example, the control unit 65 hides the second route image Im2 so that the driver cannot visually recognize it. In the second example, the control unit 65 sets the luminance of the second path image Im2 to be lower than the luminance of the first path image Im1. In this case, the control unit 65 may display the first route image Im1 as brightly as if a spotlight was applied, and display the second route image Im2 as darkly as if no spotlight was applied. In the third example, the control unit 65 highlights the first route image Im1 by adding a bordering effect or the like.

And the control part 65 determines whether it arrived at the destination (step S104). If the control unit 65 determines that it has arrived at the destination (step S104; Yes), it is not necessary to display a route image, and thus the process of the flowchart ends. On the other hand, when it has not arrived at the destination (step S104; No), the control unit 65 returns the process to step S102, and re-establishes the first route unit R1 and the second route unit R2 based on the current position of the vehicle Ve. Recognize and display the route image.

(2) Specific Example Next, a specific example of the route image display process will be described with reference to FIGS.

FIG. 6 (A) is a diagram showing a positional relationship between the first path portion R1 and the second path portion R2 when approaching the intersection where the U-turn is performed. In FIG. 6A and FIG. 6B described later, the first path portion R1 is indicated by a solid line, and the second path portion R2 is indicated by a broken line.

In the example of FIG. 6 (A), the control unit 65 sets the first guide route that is within the distance Lth along the guide route from the current position indicated by the host vehicle position mark 21 and is in front of the intersection 70 that makes a U-turn. Recognized as a route part R1. Further, the control unit 65 recognizes, as the second route portion R2, a guide route that is separated from the current position indicated by the host vehicle position mark 21 along the guide route from the distance Lth and includes the route after turning back at the intersection 70.

As in the example of FIG. 6A, when the vehicle Ve makes a U-turn in the opposite lane of the currently running lane, the guide route before the U-turn and the guide route after the U-turn are close to each other. . Therefore, when the head-up display 2 displays a route image in association with the guidance route included in the forward scenery, in addition to the route image corresponding to the guidance route before the U-turn, the route corresponding to the guidance route after the U-turn. It is also necessary to display an image. On the other hand, the second route portion R2 including the guide route after the U-turn is separated from the current position by a distance Lth along the guide route. Therefore, the driver does not need to recognize the second path portion R2 immediately after driving.

Considering the above, the head-up display 2 displays the second path image Im2 corresponding to the second path part R2 in a less conspicuous manner than the first path image Im1 corresponding to the first path part R1. Thereby, the head-up display 2 can suitably suppress the driver's field of view from being unnecessarily blocked by the route image. A display example corresponding to FIG. 6A will be described later with reference to FIG.

FIG. 6 (B) is a diagram showing the first route portion R1 and the second route portion R2 when approaching the loop road.

In the example of FIG. 6B, the control unit 65 recognizes a portion that is within a distance Lth along the guide route from the current position indicated by the host vehicle position mark 21 and that has reached the loop road as the first route unit R1. To do. In addition, the control unit 65 recognizes, as the second route part R2, a route that is separated from the current position indicated by the vehicle position mark 21 along the guide route by a distance Lth and includes a looping part.

When the vehicle Ve travels on a loop type road as in the example of FIG. 6 (B), in addition to the road that is currently traveling, the head up is performed not only on the road that loops up and down the road that is currently traveling. It is included in the display range of the display 2. On the other hand, as in FIG. 6A, the second route portion R2 including the route after the loop is separated from the current position by the distance Lth along the guide route. There is no need to be aware of. Therefore, in this case, the head-up display 2 displays the second path image Im2 corresponding to the second path part R2 in a less conspicuous manner than the first path image Im1 corresponding to the first path part R1. Thereby, the head up display 2 can suppress suitably that the display which overlaps with a landscape becomes complicated.

Next, a specific display example of the head-up display 2 will be described. FIG. 7 shows an example of the driver's field of view under the same situation as FIG.

In the example of FIG. 7, the control unit 65 displays only the cable-shaped first route image Im1 corresponding to the first route portion R1 as the route image, and operates the second route image Im2 corresponding to the second route portion R2. It is hidden so that no one can see it. In FIG. 7, for convenience of explanation, the outer edge of the second route image Im2 is indicated by a broken line. In this way, the control unit 65 determines that the driver does not necessarily need the information for the second route portion R2 that is separated from the current position along the guide route by the distance Lth, and hides the second route image Im2. To do. Thereby, the head-up display 2 can suitably suppress the scenery from being blocked from view by the second path image Im2.

On the other hand, if the head-up display 2 displays the second route image Im2 of the second route part R2 in the same manner as the first route image Im1 of the first route part R1, the head-up display 2 displays the second route image Im2 in the landscape. (A building in FIG. 7) is displayed in an overlapping manner, and the driver's view is obstructed unnecessarily. As described above, since the head-up display 2 displays the scene that is actually viewed by the driver, it is necessary to narrow down the information to be displayed only to the information that the driver needs most recently.

In consideration of the above, in FIG. 7, the head-up display 2 hides the second route image Im2 of the second route portion R2 that the driver does not need to know immediately, and the driver should know immediately. The first path image Im1 of the first path part R1 is displayed. Thereby, the head-up display 2 can suppress the complication of the display which overlaps with scenery, and can improve a driver | operator's visibility.

As described above, the head-up display 2 according to the present embodiment displays a route image indicating the guide route to the destination in association with the guide route so as to overlap with the scenery seen in front of the vehicle Ve. The control unit 65 of the head-up display 2 functions as a display control unit, and the first route image Im1 corresponding to the first route part R1 within the predetermined range from the current position in the guide route, and the guide route The display mode is changed with the second route image Im2 corresponding to the second route part R2 outside the predetermined range from the current position. Thereby, the head-up display 2 can suppress the complication of the display which overlaps with scenery, and can improve a driver | operator's visibility suitably.

[Modification]
Hereinafter, modified examples suitable for the above-described embodiments will be described. The following modifications may be applied in any combination to the above-described embodiments.

(Modification 1)
In step S102 of FIG. 5, the control unit 65 divides the guide route into the first route portion R1 and the second route portion R2 based on the distance from the current position along the guide route. However, the method to which the present invention is applicable is not limited to this.

Alternatively, the control unit 65 may divide the guide route into the first route unit R1 and the second route unit R2 based on the estimated required time considering the traffic jam information. Specifically, the control unit 65 recognizes, as the first route unit R1, a route that is within a predetermined time (also referred to as “time Tth”) within the guidance route, in which the estimated required time considering traffic jam information is considered. The guide route other than the one route part R1 is recognized as the second route part R2. The above-described time Tth is a threshold value of an estimated required time for determining whether or not the route should be immediately known by the driver, and is set to an appropriate value (for example, 1 minute) in advance based on, for example, an experiment. Stored in the memory of the unit 65.

In this case, for example, the control unit 65 calculates the estimated required time to each point of the guide route based on the presence / absence of traffic jams and the presence / absence of intersections in addition to the distance from the current position. At this time, the control unit 65 uses the communication unit 64 to acquire traffic jam information such as VICS information or to refer to map data stored in the guide route navigation device 1. And the control part 65 recognizes 1st path | route part R1 and 2nd path | route part R2 based on the estimated required time of each point and time Tth. And the control part 65 sets the 2nd path | route image Im2 corresponding to the above-mentioned 2nd path | route part R2 to a display mode which is not conspicuous rather than the 1st path | route image Im1 corresponding to the above-mentioned 1st path | route part R1.

Thus, also by this modification, the control unit 65 may more accurately determine whether the driver is route information necessary for the latest driving, and suitably limit the display target of the head-up display 2. it can.

(Modification 2)

FIG. 8 shows a schematic configuration diagram of a display system 100A according to the present modification. As illustrated in FIG. 8, the display system 100 A includes a server device 3 that is connected to the head-up display 2 via a network 200 and performs route search processing instead of the navigation device 1.

In this configuration, the head-up display 2 includes an input unit and a GPS receiver (not shown). When the input unit detects an input related to the destination, the information on the destination is detected by the GPS receiver. It transmits to the server apparatus 3 with information. The server device 3 performs route search processing based on the received current position information and destination information, and transmits the guide route information determined by the route search processing to the head-up display 2. Then, the head-up display 2 displays a route image as in the embodiment by executing the processing of the flowchart shown in FIG.

In addition to the configuration shown in FIG. 8, the display system 100 A may include the navigation device 1. In this case, the navigation device 1 transmits the destination information input by the input device 60 and the current position information detected by the GPS receiver 18 to the server device 3, and the route search processing result from the server device 3. As a guide route information. As in the embodiment, the navigation device 1 transmits the received guide route information to the head-up display 2, and the head-up display 2 displays a route image by executing the processing of the flowchart shown in FIG. .

In yet another configuration example, the display system 100 may include only the head-up display 2. In this case, the head-up display 2 includes a GPS receiver necessary for navigation processing, an input unit, map data, and the like, and further executes route search processing based on user input.

(Modification 3)
In the embodiment, the control unit 65 of the head-up display 2 executes the process of the flowchart shown in FIG. 5, but instead of this, the system controller 20 of the navigation device 1 may execute the process of the flowchart shown in FIG. Good.

In this case, the system controller 20 first determines the guide route by route search processing in step S101, and then in step S102 divides the guide route into the first route portion R1 and the second route portion R2. Thereafter, in step S103, the system controller 20 instructs to display the second path image Im2 corresponding to the second path part R2 so that it is less conspicuous than the first path image Im1 corresponding to the first path part R1. A signal is transmitted to the head-up display 2.

As described above, also in the present modification, the head-up display 2 may make the second route image Im2 less conspicuous than the first route image Im1 when displaying the route image as in the embodiment. it can. In the present modification, the navigation device 1 and the head-up display 2 are examples of the “display device” in the present invention. The navigation device 1 is an example of the “computer” in the present invention.

(Modification 4)
The display method to which the present invention can be applied is not limited to the display by the head-up display 2. Instead of this, the navigation device 1 may be connected to a camera that captures the front scenery of the vehicle Ve, and the route image may be superimposed on the actual image captured by the camera and displayed on the display unit 40.

FIG. 9 shows a display example of the display 44 of the display unit 40 in which a route image is superimposed on a real image captured by the camera. In FIG. 9, it is assumed that the vehicle Ve exists at the same position as the example of FIG.

As shown in FIG. 9, the system controller 20 displays a live-action image 90 captured by the camera on the display 44, recognizes the first route portion R1 and the second route portion R2 from the guide route, and the first route portion R1. The first route image Im1 corresponding to is superimposed on the photographed image 90. In FIG. 9, as in the example of FIG. 7, the system controller 20 hides the second route image Im 2 corresponding to the second route portion R 2 that is not necessary for the driver immediately after driving so that the driver cannot visually recognize the second route image Im 2. I have to. Thereby, the system controller 20 suitably suppresses the partial display of the live-action image 90 from being unnecessarily obstructed due to the display of the second route image Im2 that the driver does not need to recognize immediately in driving. Can do.

(Modification 5)
In FIG. 3, the head-up display 2 has a combiner 9 and makes the driver visually recognize the virtual image Iv based on the emitted light of the light source unit 4 reflected by the combiner 9. However, the configuration to which the present invention is applicable is not limited to this. Instead of this, the head-up display 2 may not have the combiner 9 and may allow the driver to visually recognize the virtual image Iv based on the emitted light of the light source unit 4 reflected by the windshield 25.

Further, the position of the light source unit 4 is not limited to the case where it is installed on the ceiling portion 27. Instead, the light source unit 4 may be installed inside the dashboard 29. In this case, the dashboard 29 is provided with an opening for allowing light to pass through the combiner 9 or the windshield 25.
