The vehicle control ECU 5 is based on detection signals output from various sensors such as an accelerator position sensor, a brake pedal force sensor, a steering angle sensor, and a wheel speed sensor mounted on the own vehicle, for example, an electronically controlled throttle, a brake actuator, and the like. A control signal is output to various drive control system devices such as an EPS motor (EPS: Electric Power Steering). Further, the vehicle control ECU 5 can output detection signals obtained from various sensors to the in-vehicle LAN.

The driving support ECU 6 supports the driving operation by the driver by cooperating with the vehicle control ECU 5, for example. The support provided by the driving support ECU 6 also includes an automatic driving function that automatically controls the running of the own vehicle. The driving support ECU 6 recognizes the driving environment of the own vehicle based on the vehicle position of the own vehicle acquired from the ADAS locator 3, the map data stored in the map DB 32, the sensing data acquired from the peripheral monitoring sensor 4, and the like. More specifically, the driving support ECU 6 recognizes the position, shape, moving state, etc. of an object existing in the vicinity of the own vehicle based on, for example, sensing data acquired from the peripheral monitoring sensor 4, or the own vehicle. It is possible to recognize the position, size, contents, etc. of road markings that exist in the vicinity of. Then, the driving support ECU 6 combines the information recognized in this way with information such as map data and the vehicle position of the own vehicle to create a virtual space that reproduces the actual driving environment around the own vehicle in three dimensions. It is possible to generate.

Further, the driving support ECU 6 generates a driving plan for automatically driving the own vehicle by the automatic driving function based on the recognized driving environment. As a driving plan, a long- to medium-term driving plan and a short-term driving plan can be generated. In a short-term driving plan, the generated virtual space around the own vehicle is used, for example, acceleration / deceleration control for maintaining the target inter-vehicle distance from the preceding vehicle, steering control for lane tracking and lane change, and collision avoidance. Braking control for this is determined. In the long- to medium-term driving plan, a route search for the own vehicle to reach the destination is carried out, and a driving schedule and the like are determined. The driving support ECU 6 may generate only one of a short-term running plan and a long- and medium-term running plan, for example, a short-term running plan.

The operation device 21 includes various switches operated by the driver of the own vehicle. The operation device 21 is composed of a steering switch or the like provided on the spokes of the steering of the own vehicle. As will be described later, the operation device 21 functions as a display operation unit for the HCU 20, and has a function for operating the display or non-display of the content display on the display unit 9 such as the HUD 230, which will be described later, by operating the operation device 21.

The DSM 22 includes, for example, a light source that generates near-infrared light, a near-infrared light camera that detects near-infrared light, a control unit that controls these, and the like. The DSM 22 is arranged on, for example, on the steering column cover or the upper surface of the instrument panel in a state where the near-infrared light camera is directed toward the driver's seat of the own vehicle. The DSM 22 uses a near-infrared light camera to image the head of the driver irradiated with near-infrared light from a near-infrared light source. Then, the image captured by the near-infrared light camera is image-analyzed by a control unit (not shown). For example, this control unit extracts the driver's eyes from the captured image and detects the position of the driver's eyes with respect to the reference position set in the vehicle interior of the own vehicle as the viewpoint position. As the reference position, for example, the installation position of the near-infrared light camera can be set. Then, the DSM 22 outputs the information indicating the detected viewpoint position of the driver to the HCU 20. Further, the control unit can identify or infer the driver's line of sight, that is, the direction in which the driver's eye is heading, by performing image analysis of the image captured by the near-infrared light camera. Then, the DSM 22 outputs the line-of-sight information indicating the direction of the line-of-sight of the specified or estimated driver to the HCU 20.

The display device 23 is configured as a head-up display 230 (HUD: Head Up Display). Hereinafter, the head-up display 230 will be referred to as a HUD 230. As illustrated in FIG. 2, the HUD 230 is provided, for example, on the instrument panel 12 of the own vehicle. The HUD 230 forms a display image based on the image data output from the HCU 20 by, for example, a liquid crystal type or a scanning type projector 231. The display image is, for example, an image showing information related to vehicle route guidance.

The HUD 230 projects the display image formed by the projector 231 onto the front windshield 10, which is an example of the projection unit, via an optical system 232 having, for example, a concave mirror. The front windshield 10 is provided with a projection area R, and the display image formed by the projector 231 is projected in the projection area R. The projection area R is provided so as to be located in front of the driver's seat, particularly in front of the driver seated in the driver's seat. The driver is an example of a user.

The luminous flux of the display image projected on the front windshield 10 is perceived or visually recognized by the driver seated in the driver's seat. Further, the front windshield 10 is made of, for example, a translucent glass material, and the scenery, that is, the luminous flux in the foreground existing in front of the own vehicle is also perceived, that is, visually recognized by the driver seated in the driver's seat. To. As a result, the driver can visually recognize the virtual image of the display image formed in front of the front windshield 10 in a state of being superimposed on a part of the foreground as the virtual image content 100. That is, the HUD 230 realizes so-called AR display (AR: Augmented Reality) by superimposing the virtual image content 100 on the foreground of the own vehicle.

The virtual image content 100 is at least content that visually represents information related to the traveling support of the own vehicle, that is, traveling support-related information. Examples of the driving support-related information include route guidance-related information indicating the traveling direction of the own vehicle in the guidance route, automatic driving-related information indicating the course when the own vehicle is automatically controlled, and the lane in which the own vehicle travels. Lane information to be shown, curve notification information to notify the curve existing in front of the traveling direction of the own vehicle, pedestrian information to inform that there is a pedestrian in front of the traveling direction of the own vehicle, and a stop line in front of the traveling direction of the own vehicle. Various information can be applied as long as it is useful information for driving support of the own vehicle, such as stop line information for notifying the existence.

The projection area R on which the HUD 230 projects the virtual image content 100 is not limited to the front windshield 10, and may be configured by, for example, a translucent combiner. Further, the display device 23 may be configured by, for example, a combination meter, CUD (Center Information Display), or the like. In the present embodiment, the so-called windshield display will be described as being included in the HUD230.

The HCU 20 is mainly composed of a microcomputer including, for example, a processor, a volatile memory, a non-volatile memory, an input / output circuit, a bus connecting these, and the like. The HCU 20 is connected to the HUD 230 and the in-vehicle LAN. The HCU 20 functions as an in-vehicle display control device according to the present disclosure. The HCU 20 controls content display on display units such as the HUD 230, meter system display unit 7, and navigation display unit 8 by executing a control program stored in a storage medium such as a non-volatile memory.

This control program includes a vehicle display control program according to the present disclosure. Further, the HCU 20 executes the vehicle display control method according to the present disclosure by executing the control program. The memory is, for example, a non-transitory tangible storage medium that stores programs and data that can be read by a computer non-temporarily. Further, the non-transitional substantive storage medium can be realized by, for example, a semiconductor memory or a magnetic disk.

Further, as illustrated in FIG. 1, the vehicle system 1 further includes a meter system display unit 7. The meter system display unit 7 is an example of a display unit different from the front windshield 10 of the HUD 230, and is a display unit capable of displaying meter system information such as the traveling speed of the own vehicle and the rotation speed of the engine. Further, as will be described later, the meter system display unit 7 can display various types of information such as travel support-related information represented by the virtual image content 100 in a mode different from that of the virtual image content 100, for example, a liquid crystal display.

Further, the vehicle system 1 further includes a navigation display unit 8. The navigation display unit 8 constitutes a display of a navigation device mounted on the vehicle, and the route information to the destination searched by the navigation device is displayed on the navigation display unit 8. The navigation display unit 8 is an example of a display unit different from the front windshield 10 of the HUD 230. Further, the navigation display unit 8 can display various kinds of information such as the traveling support related information represented by the virtual image content 100 in a mode different from that of the virtual image content 100, for example, a liquid crystal display.

In the following description, the meter system display unit 7, the navigation display unit 8, and the projection area R of the HUD 230 may be collectively referred to as the display unit 9. Further, these display units 9 are drawing ranges in which the HCU 20 can draw various information. In the above description, the route search is performed by the navigation device, and the route information is displayed on the navigation display unit 8. Instead of this, the route information by the route search performed by the driving support ECU 6 is navigated. It may be displayed on the display unit 8. In this case, the navigation device or the driving support ECU 6 functions as a route search unit in the vehicle system 1, and the route information searched by the route search unit is output to the navigation display unit 8 to be output to the navigation display unit 8. Is displayed in.

As illustrated in FIG. 3, the projection area R of the HUD 230 is provided so as to be located in front of the driver's seat in the front windshield 10. Further, the meter system display unit 7 is provided on the instrument panel 12 at a position below the projection region R of the HUD 230 in front of the driver's seat. Further, the navigation display unit 8 is provided at a substantially central portion in the left-right direction of the instrument panel 12. The arrangement positions of the various display system components shown in FIG. 3 are merely examples, and the arrangement positions of the respective display system components can be appropriately changed and implemented.

The HCU 20 executes a process of projecting the virtual image content 100 into the projection area R of the front windshield 10 so as to superimpose it on the foreground of the own vehicle. The content display indicating the direction of the destination, which will be described later, is displayed as the virtual image content 100.

Next, an in-vehicle display control device according to the present disclosure, in this case, an example of control by the HCU 20 will be described. As illustrated in FIG. 4, the HCU 20 determines whether or not the own vehicle is in a traffic jam (S1). Whether or not the own vehicle is in a traffic jam is determined by, for example, the vehicle speed data from the vehicle speed sensor provided in the vehicle. The vehicle speed data may be calculated from the position and time of the own vehicle sequentially positioned by the ADAS locator 3. Further, for example, it may be determined whether or not the own vehicle is encountering the traffic jam based on the traffic jam information acquired from the outside of the own vehicle via a communication module mounted on the vehicle or the like.

If the HCU 20 determines that the own vehicle has not encountered a traffic jam (S1: NO), it continues to determine whether or not the own vehicle has encountered a traffic jam (S1). When the HCU 20 determines that the vehicle is in a traffic jam (S1: YES), the HCU 20 determines whether or not there is a loophole for the route to the current destination (S2).

To determine whether or not there is a loophole, for example, the HCU 20 sends a request to the driving support ECU 6 to search for a route different from the route currently being traveled by the own vehicle, and the search for another route is required. This can be done depending on whether or not the difference between the time and the required time due to the route currently being driven is within the predetermined time. For example, if the difference in the required time is within the predetermined time, it is determined that there is a loophole. can do. The search for another route is based on, for example, congestion information acquired from the outside of the own vehicle via a communication module mounted on the vehicle, and is a search condition based on a route that does not pass through the congestion section where the own vehicle is encountering congestion. It may be executed by.

When the HCU 20 determines that there is no loophole to the destination (S2: NO), the HCU 20 returns to the original state and continues to determine whether or not the vehicle is in a traffic jam (S1). When the HCU 20 determines that there is a loophole (S2: YES), the HCU 20 determines whether or not the own vehicle is traveling on the highway (S3). Whether or not the own vehicle is traveling on the highway is determined based on the position data received by the HCU 20 from the ADAS locator 3. The position data of the own vehicle is specified by the ADAS locator 3 using the sensor information acquired by the GNSS receiver 30 and the inertial sensor 31 and the map data stored in the map DB 32.

When the HCU 20 determines that the own vehicle is traveling on the highway (S3: YES), the HCU 20 returns to the original state and continues to determine whether or not the own vehicle is in a traffic jam (S1). When the HCU 20 determines that the own vehicle is not traveling on the highway (S3: NO), the HCU 20 executes the display of the content display 11 to 15, that is, the direction display indicating the direction of the destination of the own vehicle (S4). As described above, the HCU 20 depends on whether the road on which the own vehicle is traveling is an expressway, that is, the type of road on which the own vehicle is traveling, in other words, the type of driving road on which the own vehicle is traveling. To determine whether or not the content display can be displayed. The content of the content display displayed in the direction display will be described later.

After performing the direction display (S4), the HCU 20 determines whether or not the display of the content display, that is, the end condition of the direction display is satisfied (S5). The condition for ending the content display is when the traffic jam ends, when the route to the destination is rerouted, or when the own vehicle enters a loophole. If the end condition of the direction display is not satisfied (S5: NO), the HCU 20 continues the direction display (S4). When the end condition of the direction display is satisfied (S5: YES), the HCU 20 executes a process of ending the direction display (S6). As described above, the display process of the content display is completed by the HCU 20.

Hereinafter, the content displays 11 to 15 displayed in the direction display indicating the direction of the destination of the own vehicle in step S4 will be described with reference to FIGS. 5 to 9.
The embodiment described with reference to FIG. 5 below is a case where the direction of the destination exists in the display unit 9, that is, the drawing range. The content display 11 showing the direction of the destination of the own vehicle shown in FIG. 5 shows a display example displayed on the meter system display unit 7 or the navigation display unit 8 as the display unit 9. In this case, the direction of the destination is indicated by displaying the content display 11 indicating the direction of the destination of the own vehicle. The direction of the destination is indicated by the direction of the arrow of the content display 11. Whether or not the driver recognizes the content display 11 displayed on the display unit 9 to change the route from which the own vehicle is currently traveling to a route using the loophole in the direction indicated by the content display 11. It becomes easy to make a judgment.

Although the content display 11 is displayed by the mark symbolizing the arrow in FIG. 5, the content display 11 may be a mark or the like having another shape. For example, the direction of the destination of the own vehicle may be set as the content display 11 indicating the direction of the destination of the own vehicle by arranging, for example, a mark symbolizing a circle mark at the position of the destination on the display unit 9. ..

In FIG. 5, as described above, when the HCU 20 determines that the own vehicle is not traveling on the highway (S3: NO), the control for displaying the content display indicating the direction of the destination of the own vehicle is illustrated. However, instead of the above control, the control of the HCU 20 may be operated by the operation of the operation device 21 by a driver or the like, whereby the content display 11 may be displayed on the display unit 9. In this way, the direction of the destination of the own vehicle can be confirmed at any time by the operation of the driver. Further, the content display indicating the home direction may be displayed by operating the operation device 21 by a driver or the like.

Next, the embodiment described with reference to FIG. 6 is applied to both the case where the direction of the destination exists in the display unit 9, that is, the drawing range, and the case where the direction of the destination does not exist in the drawing range. it can. The content display 12 showing the direction of the destination of the own vehicle shown in FIG. 6 shows a display example displayed on the meter system display unit 7 or the navigation display unit 8 as the display unit 9. In this case, the direction of the destination is indicated by displaying the content display 12, which is a map display showing a reduced map in which the entire route from the current location of the own vehicle to the destination is reduced to a recognizable scale. By recognizing the content display 12 displayed on the display unit 9, the driver changes the route from which the own vehicle is currently traveling to a route using a loophole in the direction of the destination indicated by the content display 12. It becomes easy to judge whether or not.

In the above example, as the content display indicating the direction of the destination, the content display 12 showing a reduced map capable of recognizing the entire route from the current location of the own vehicle to the destination is illustrated, but instead of this, the scale is scaled. A content display showing an enlarged map of the image may be displayed. By displaying the content display showing the enlarged map, the road conditions around the vehicle can be grasped in detail, and it becomes easy to judge whether or not the vehicle can enter the loophole in a timely manner from the road on which the vehicle is currently traveling. ..

Next, a display example of the content display to be displayed when the direction of the destination does not exist in the display unit 9, that is, the drawing range, will be described with reference to FIGS. 7 to 9.

The contents displays 13 and 14 shown in FIGS. 7 and 8 show a display example displayed as the display unit 9 in the projection area R of, for example, the front windshield 10. In this case, the direction of the destination is indicated by displaying the content display 13 or the content display 14 shown in the projection area R.

In FIG. 7, the content display 13 is displayed as a fan shape arranged in the upper right corner of the rectangular projection area R. In this example, the content display 13 indicates that the destination exists in the right-hand direction with respect to the traveling direction of the own vehicle. Whether or not the driver recognizes the content display 13 displayed on the display unit 9 to change the route from which the own vehicle is currently traveling to a route using the loophole in the direction indicated by the content display 13. It becomes easy to make a judgment.

In FIG. 8, the content display 14 is displayed as a fan shape arranged in the lower right corner of the rectangular projection area R. In this example, the content display 14 indicates that the destination exists behind the right hand side with respect to the traveling direction of the own vehicle. Whether or not the driver recognizes the content display 14 displayed on the display unit 9 to change the route from which the own vehicle is currently traveling to a route using the loophole in the direction indicated by the content display 14. It becomes easy to make a judgment.

In FIG. 9, the content display 15 shows another example of the content display displayed in the rectangular projection area R. In FIG. 9, the content display 15 is displayed so as to be a strip-shaped horizontally long rectangle arranged along the side located at the upper part of the horizontally long rectangular projection area R. In this example, the content display 15 indicates that the destination exists behind the traveling direction of the own vehicle. Whether or not the driver recognizes the content display 15 displayed on the display unit 9 to change the route from which the own vehicle is currently traveling to a route using the loophole in the direction indicated by the content display 15. It becomes easy to make a judgment.

As described above with reference to FIGS. 5 to 9, the display method of the content display when the direction of the destination exists in the display unit 9, that is, the drawing range, and the direction of the destination exists in the drawing range. If not, the display method of the content display is different.

In the description of the above embodiment, in step S4 for carrying out the direction display, an example of displaying the content displays 11 to 15 indicating the direction of the destination of the own vehicle is shown, but instead of the content display indicating the direction of the destination, Alternatively, the content display indicating the direction of the home may be displayed in addition to the content display indicating the direction of the destination. Similar to the above, the display method may be the same as above, when the content display indicating the home direction is displayed in the display unit 9, and when the home direction exists in the display unit 9, the display method shown in FIG. 5 may be adopted. it can. Further, when the home direction does not exist in the display unit 9, the display methods shown in FIGS. 7 to 9 can be adopted.
