Description
[Technical Field]
[0001] The present invention relates to a vehicle display control device, a vehicle display control system, a vehicle, a vehicle display control method, and a program. [Background technology]
[0002] Patent Document 1 discloses a vehicle display device that displays an image on the windshield using a head-up display device. This vehicle display device detects a guidance point where the vehicle must turn, and displays guidance marks superimposed on the road surface before and after the guidance point. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-21019 Summary of the Invention [Problem to be solved by the invention]
[0004] However, the device described in Patent Document 1 does not take into consideration the conditions for superimposing and displaying the guidance mark, so there is a possibility that the guidance mark will be displayed even if displaying the guidance mark would confuse the occupants.
[0005] An object of the present invention is to provide a vehicle display control device, a vehicle display control system, a vehicle, a vehicle display control method, and a program that can prevent occupants from becoming confused. [Means for solving the problem]
[0006] The vehicle display control device according to claim 1 includes an intersection information acquisition unit that acquires information about intersections that the vehicle is scheduled to pass through from a predetermined planned driving route of the vehicle, and an image display unit that, when the vehicle approaches the intersection, superimposes an animation of the vehicle heading toward the intersection on a display area provided in front of the occupant, and does not display the animation if the intersection satisfies the predetermined condition. a plurality of relay points are set on a planned driving route to the intersection, and if all of the relay points are within the range of the angle of view of the display area, the intersection is determined to be one at which animation is to be superimposed; and if a part of the relay points is not within the range of the angle of view of the display area, the intersection is determined to be one at which animation is not to be superimposed. .
[0007] In the vehicle display control device according to claim 1, the intersection information acquisition unit acquires information about intersections that the vehicle is scheduled to pass through from a preset planned driving route of the vehicle. Furthermore, when the vehicle approaches an intersection, the image display unit displays an animation of the vehicle heading toward the intersection superimposed on the foreground in a display area provided in front of the occupant. This allows the occupant to intuitively grasp the location of the intersection.
[0008] Furthermore, the image display unit does not display animation if the intersection satisfies predetermined conditions. As a result, display of animation is prohibited in cases where displaying animation would mislead occupants, such as at intersections with unusual shapes. Note that the term "superimposed display" as used herein is not limited to a configuration in which an image is superimposed on the foreground seen through the windshield glass, but is a broad concept that includes a configuration in which an image is superimposed on the foreground displayed on a display inside the vehicle.
[0009] A vehicle display control device according to claim 2 is the device of claim 1, wherein the image display unit does not display animation when the intersection shape is classified into a predetermined classification.
[0010] In the vehicle display control device according to claim 2, whether to display animation is determined based on the intersection shape classification. This makes it possible to easily determine whether to display animation by only referring to the shape classification information in the intersection information, thereby reducing the processing load.
[0011] The vehicle display control device of claim 3 is the same as claim 1, wherein the image display unit does not display the animation when at least a portion of the planned driving route from the vehicle's current position to the intersection is outside the angle of view of the display area.
[0012] In the vehicle display control device according to claim 3, if at least a part of the planned driving route to the intersection falls outside the viewing angle of the display area and the animation becomes unrecognizable along the way, the animation is not displayed, thereby preventing confusion among occupants.
[0013] A vehicular display control device according to claim 4 is the vehicle display control device according to claim 1, wherein when the distance between two intersections to be passed is equal to or shorter than a predetermined distance, the image display unit: displaying the animation for a first intersection; and The animation is not displayed for the second intersection.
[0014] In the vehicle display control device according to claim 4, when there are successive intersections, only the animation for the first intersection is displayed, thereby preventing the animation from being displayed successively and preventing confusion among occupants.
[0015] The vehicle display control device of claim 5 is the same as claim 1, and further includes a current location information acquisition unit that acquires current location information of the vehicle, and the image display unit does not display the animation when the reliability of the current location information is low.
[0016] In the vehicle display control device according to claim 5, animation is not displayed when the reliability of the vehicle's current location information is low, thereby avoiding a situation where animation is displayed in a direction different from the actual intersection.
[0017] The vehicle display control device of claim 6 is claim 1, wherein the image display unit displays information about the intersection as a still image when the distance to the intersection is equal to or less than a predetermined first distance, and displays the animation when the distance to the intersection is equal to or less than a second distance that is shorter than the first distance.
[0018] In the vehicle display control device according to claim 6, information about the intersection is displayed as a still image until the distance to the intersection is sufficiently close, thereby making the occupant aware in advance that they are approaching the intersection. Then, animation is displayed thereafter, allowing the occupant to intuitively grasp the location of the intersection.
[0019] A vehicle display control system according to a seventh aspect of the present invention includes the vehicle display control device according to any one of the first to sixth aspects of the present invention, and a display device that displays the animation in the display area.
[0020] A vehicle according to an eighth aspect of the present invention includes the vehicle display control system according to the seventh aspect of the present invention.
[0021] A display control method for a vehicle according to claim 9 includes acquiring information about an intersection that the vehicle is scheduled to pass through from a predetermined planned driving route of the vehicle, and if the intersection does not satisfy a predetermined condition, superimposing an animation of the vehicle heading toward the intersection on a display area provided in front of a vehicle occupant as the vehicle approaches the intersection, and prohibiting the display of the animation if the intersection satisfies the predetermined condition. a plurality of relay points are set on a planned driving route to the intersection, and if all of the relay points are within the range of the angle of view of the display area, the intersection is determined to be one at which animation is to be superimposed; and if a part of the relay points is not within the range of the angle of view of the display area, the intersection is determined to be one at which animation is not to be superimposed. .
[0022] The program according to claim 10 is a program for detecting intersections to be passed from a predetermined planned travel route of a vehicle. When the intersection information is acquired and the intersection does not satisfy a predetermined condition, an animation of the vehicle heading toward the intersection is superimposed on the foreground in a display area provided in front of the occupant as the vehicle approaches the intersection, and when the intersection satisfies the predetermined condition, the display of the animation is prohibited. a plurality of relay points are set on a planned driving route to the intersection, and if all of the relay points are within the range of the angle of view of the display area, the intersection is determined to be one at which animation is to be superimposed; and if a part of the relay points is not within the range of the angle of view of the display area, the intersection is determined to be one at which animation is not to be superimposed. , and have the computer execute the processing.

[0025] A vehicle display control system 10 including a vehicle display control device 28 according to an embodiment will be described with reference to the drawings. Note that the arrow UP in Fig. 1 indicates the upper side in the vehicle vertical direction, and the arrow RH indicates the right side in the vehicle width direction. In the following description, the vertical direction and the left-right direction refer to the up and down in the vehicle vertical direction and the left and right in the vehicle width direction, respectively.
[0026] 1, an instrument panel 14 is provided in the front portion of the cabin of a vehicle 12. The instrument panel 14 extends in the vehicle width direction, and a steering wheel 16 is provided on the right side of the instrument panel 14. That is, in this embodiment, as an example, the vehicle is a right-hand drive vehicle in which the steering wheel 16 is provided on the right side, and the driver's seat is located on the right side of the vehicle.
[0027] A windshield glass 18 is provided at the front end of the instrument panel 14. The windshield glass 18 extends in the vertical direction and the width direction of the vehicle, and separates the interior of the vehicle from the exterior of the vehicle.
[0028] The right end of the windshield glass 18 is fixed to a front pillar 20 on the right side of the vehicle. The front pillar 20 extends in the vertical direction of the vehicle, and the windshield glass 18 is fixed to the inner end of the front pillar 20 in the vehicle width direction. In addition, the front ends of front side windows 22 are fixed to the outer end of the front pillar 20 in the vehicle width direction. The left end of the windshield glass 18 is fixed to a front pillar on the left side of the vehicle (not shown).
[0029] Here, a first display unit 24 having an image display area V1 is provided on the instrument panel 14. The first display unit 24 is configured as a meter display provided in front of the driver's seat on the vehicle right side of the instrument panel 14. The first display unit 24 is connected to various meter devices mounted on the vehicle 12, and is provided in a position within the driver's field of view when the driver is looking forward.
[0030] The instrument panel 14 is provided with a second display unit 25 having an image display area V2. The second display unit 25 is configured by a center display disposed in the center of the instrument panel 14 in the vehicle width direction.
[0031] The windshield glass 18 is provided with a third display unit 26 having an image display area V3. The third display unit 26 is set above the first display unit 24 and is configured as a projection surface onto which an image is projected by a head-up display device 46 (see FIG. 2 ) serving as a display device. Specifically, the head-up display device 46 capable of projecting an image is provided on the vehicle front side of the instrument panel 14, and an image is projected from this head-up display device 46 onto the third display unit 26 of the windshield glass 18. In other words, the third display unit 26 is configured as part of the windshield glass 18 that serves as the projection surface for the head-up display device 46.
[0032] Here, the vehicle 12 is provided with a vehicle display control device 28 that constitutes the vehicle display control system 10. The vehicle display control device 28 of this embodiment is, for example, an ECU (Electronic Control Unit) that performs various controls.
[0033] (Hardware configuration of the vehicle display control device 28) 2, the vehicle display control device 28 includes a CPU (Central Processing Unit: processor) 30, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 34, a storage 36, a communication interface (communication I / F) 38, and an input / output interface (input / output I / F) 40. Each component is connected to each other via an internal bus 42 so as to be able to communicate with each other.
[0034] The CPU 30 is a central processing unit that executes various programs and controls each part. That is, the CPU 30 reads programs from the ROM 32 or storage 36 and executes the programs using the RAM 34 as a work area. The CPU 30 also controls the above-mentioned components and performs various arithmetic processing in accordance with the programs recorded in the ROM 32 or storage 36.
[0035] The ROM 32 stores various programs and various data. The RAM 34 temporarily stores programs or data as a working area. The storage 36 is configured by an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and is a non-temporary recording medium that stores various programs including an operating system and various data. In this embodiment, the ROM 32 or the storage 36 stores a display program for performing image display processing and the like.
[0036] The communication interface 38 is an interface through which the vehicle display control device 28 communicates with a server and other devices, and uses standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), and Wi-Fi (registered trademark).
[0037] The input / output interface 40 is connected to a gaze detection sensor 44, the first display unit 24, the second display unit 25, and a head-up display device 46. An image is projected onto the third display unit 26 by the head-up display device 46.
[0038] The gaze detection sensor 44 is provided, for example, on the instrument panel 14, and is arranged facing the face of the occupant (driver) seated in the driver's seat. The gaze detection sensor 44 detects the gaze direction of the occupant by recognizing the eyes of the occupant using principles such as the corneal reflex method and the scleral reflex method.
[0039] (Functional configuration of the vehicle display control device 28) The vehicular display control device 28 uses the above hardware resources to realize various functions. The functional configuration realized by the vehicular display control device 28 will be described with reference to FIG.
[0040] 3, the vehicle display control device 28 is configured to include, as functional components, a planned driving route acquisition unit 52, an intersection information acquisition unit 54, a current position information acquisition unit 56, a display possibility determination unit 58, and an image display unit 60. Each functional component is realized by the CPU 30 reading and executing a program stored in the ROM 32 or storage 36.
[0041] The planned driving route acquisition unit 52 acquires information about the planned driving route set by a navigation system or the like. For example, the planned driving route to the destination is set when the occupant inputs the destination into the navigation system or the like. The planned driving route includes information about roads along which the vehicle is to travel, and information about intersections where the vehicle will change course, such as turning right or left.
[0042] The planned driving route may be stored in a storage mounted on the vehicle 12, or may be stored outside the vehicle 12, such as in a server. When the planned driving route is stored in the storage of the vehicle 12, the planned driving route acquisition unit 52 accesses the storage to acquire information about the planned driving route. When the planned driving route is stored in a server or the like outside the vehicle 12, the planned driving route acquisition unit 52 may acquire the planned driving route from the server via the communication I / F 38.
[0043] The intersection information acquisition unit 54 acquires information about intersections that are to be passed from a predetermined planned driving route of the vehicle 12. In the present embodiment, as an example, information about intersections that are to be passed within a range of a predetermined distance from the vehicle 12 is acquired, but this is not limited thereto, and information about all intersections that are to be passed on the way to the destination may be acquired.
[0044] The current position information acquisition unit 56 acquires the current position of the vehicle 12. For example, the current position information acquisition unit 56 may acquire information from a GPS (Global Positioning Systems) sensor (not shown) mounted on the vehicle 12.
[0045] The display possibility determination unit 58 determines whether or not to display a predetermined animation. Specifically, if the intersection is an intersection that satisfies predetermined conditions, the display possibility determination unit 58 determines that the intersection is an intersection where animation should not be displayed. Furthermore, if the intersection is not an intersection that satisfies predetermined conditions, the display possibility determination unit 58 determines that the intersection is an intersection where animation should be displayed.
[0046] As an example in this embodiment, the display possibility determination unit 58 determines that an intersection at which animation should not be displayed is an intersection where the shape category of the intersection that the vehicle is to pass through corresponds to a predetermined category. FIG. 4 is a table showing the identification numbers and shapes of intersections with special shapes. In FIG. 4, intersections with identification numbers 003 to 007 are intersections that correspond to a predetermined category, and the display possibility determination unit 58 determines that the intersections at which animation should not be displayed are intersections. Furthermore, intersections with identification numbers 001 and 002 are intersections at which animation should be displayed. Note that intersections with ordinary shapes that are not special shapes are not shown in FIG. 4.
[0047] The intersection with the identification number 001 is an intersection where you turn right according to the road, and the intersection with the identification number 002 is an intersection where you turn left according to the road. For example, an intersection where you enter a service road from a priority road is an intersection where you turn right or left according to the road.
[0048] The intersection with identification number 003 is an intersection where you make a U-turn to the right, and the intersection with identification number 004 is an intersection where you make a U-turn to the left. These intersections are intersections where the path changes 180 degrees from the direction of travel.
[0049] The intersection with the identification number 005 is an intersection with a right-hand Michigan turn, and the intersection with the identification number 006 is an intersection with a left-hand Michigan turn. These intersections exist only in certain areas. Similarly, the intersection with the identification number 007 is an intersection with a hook turn that exists only in certain areas.
[0050] Furthermore, if at least a part of the planned driving route from the current position of the vehicle 12 to the intersection is outside the angle of view of the display area, the display possibility determining unit 58 determines that the intersection is one for which animation should not be displayed.
[0051] Fig. 5 is a diagram schematically showing a road from a vehicle to an intersection. As shown in Fig. 5, a plurality of relay points N1 to N5 are set on the planned driving route of the vehicle 12. The vehicle 12 and relay point N1 are connected by link L1, and relay point N1 and relay point N2 are connected by link L2. Furthermore, relay point N2 and relay point N3 are connected by link L3, and relay point N3 and relay point N4 are connected by link L4. Furthermore, relay point N4 and relay point N5 are connected by link L5.
[0052] In Fig. 5, relay points N1 to N3 are included within the range of the angle of view AV of the display area. In this case, the display possibility determination unit 58 determines that the intersection is one where animation should be displayed, because the entire planned driving route from the current position of the vehicle 12 to the intersection is included within the angle of view AV of the display area. On the other hand, in Fig. 5, if the curve to the intersection is sharp, some of relay points N1 to N3 may not be included within the range of the angle of view AV of the display area. In such a case, the display possibility determination unit 58 determines that the intersection is one where animation should not be displayed.
[0053] Furthermore, the display possibility determination unit 58 does not display animation when the reliability of the current location information of the vehicle 12 acquired by the current location information acquisition unit 56 is low. For example, when the GPS reception sensitivity is low, the reliability of the current location information of the vehicle 12 is low, so the display possibility determination unit 58 determines that the intersection is one where animation should not be displayed. Note that the reliability of the current location information of the vehicle 12 may be acquired immediately before the animation is displayed.
[0054] 3, the image display unit 60 displays a still image and an animation of a vehicle heading toward an intersection superimposed on the foreground in a display area provided in front of the occupant. Specifically, the image display unit 60 displays information about the intersection as a still image in the display area when the distance to the intersection is equal to or shorter than a predetermined first distance, and displays an animation in the display area when the distance to the intersection is equal to or shorter than a second distance that is shorter than the first distance. Also, in this embodiment, as an example, the image display unit 60 displays an image and an animation in the display area V3 of the third display unit 26 using the head-up display device 46.
[0055] Fig. 6 shows an example of the display in the display area V3 when the distance to the intersection is equal to or shorter than a first distance. As shown in Fig. 6, the image display unit 60 displays a still image M1 and a still image M2 in the display area V3. In the present embodiment, as an example, the image display unit 60 displays the still image M1 in the display area V3 when the distance to the intersection is equal to or shorter than 300 m. Note that the still image M2 is always displayed while the vehicle 12 is traveling, and indicates the speed of the vehicle 12.
[0056] The still image M1 shows the direction to turn at the intersection and the distance to the intersection. The distance to the intersection may be changed depending on the current position of the vehicle 12.
[0057] Fig. 7 shows an example of the display in the display area V3 when the distance to the intersection is equal to or shorter than the second distance. As shown in Fig. 7, an animation M3 is displayed in the display area V3 by the head-up display device 46. In this embodiment, as an example, the image display unit 60 displays the animation M3 in the display area V3 when the distance to the intersection is equal to or shorter than 80 m.
[0058] Specifically, when the distance to the intersection is 80 meters or less, the image display unit 60 deletes the display of image M1. Then, in place of image M1, the image display unit 60 displays animation M3, which shows the two images moving along a virtual line as seen by the occupant. Also, in Figure 5, if the planned driving route curves, such as at relay point N2, animation M3 is displayed as if the vehicle is moving toward relay point N3, which is an intersection, while tracing a smooth curve along the planned driving route.
[0059] In this embodiment, when the display possibility determination unit 58 determines that the intersection is one where the animation M3 should not be displayed, the image display unit 60 displays only the still image M1 and does not display the animation M3. Therefore, the state in which the still image M1 is displayed is maintained until the intersection is reached. Therefore, even at an intersection where the animation M3 should not be displayed, the still image M1 is displayed, allowing the occupant to grasp information about the intersection.
[0060] 3, if the distance between two intersections to be passed is equal to or less than a predetermined distance, the display determination unit 58 does not display the animation M3 for the second intersection. Specifically, if the distance between the intersections is equal to or less than 95 m, the display determination unit 58 does not display the animation M3 for the second intersection. If the animation M3 were to be displayed even when the distance between the intersections is equal to or less than 95 m, after the vehicle 12 passes the first intersection, the still image M1 would be displayed momentarily, and the animation M3 would be displayed immediately thereafter, which may cause discomfort to the occupants.
[0061] (action) Next, the operation of this embodiment will be described.
[0062] (Image display processing) An example of image display processing for displaying a still image M1 and an animation M3 on the third display unit 26, which is the projection screen of the head-up display device 46, will be described with reference to the flowchart shown in Fig. 8. This image display processing is executed by the CPU 30 reading a display program from the ROM 32 or storage 36, expanding the program in the RAM 34, and executing it. The image display processing is also executed when the vehicle 12 approaches an intersection.
[0063] In step S102, the CPU 30 acquires intersection information. Specifically, the CPU 30 uses the function of the intersection information acquisition unit 54 to acquire information about intersections that the vehicle 12 is scheduled to pass through within a predetermined distance from the vehicle 12.
[0064] In step S104, CPU 30 displays still image M1. Specifically, when the distance to the intersection becomes equal to or shorter than the first distance, CPU 30 causes the image display unit 60 to project still image M3 from the head-up display device 46 onto display area V3, thereby superimposing still image M3 on the foreground of display area V3.
[0065] In step S106, the CPU 30 determines whether the intersection through which the vehicle 12 is scheduled to pass is in a predetermined category. Specifically, the CPU 30 refers to the table in Fig. 4 using the function of the display possibility determination unit 58. If the intersection category is one of the intersections with identification numbers 003 to 007 in Fig. 4, the CPU 30 ends the image display process. In this case, the CPU 30 ends the display of the still image M1 after the vehicle 12 passes through the intersection, and does not display the animation M3.
[0066] On the other hand, if the intersection category is not one of the intersections with identification numbers 003 to 007 in FIG. 4 in step S106, the CPU 30 proceeds to the process of step S108.
[0067] In step S108, the CPU 30 determines whether the reliability of the location information is low. Specifically, if the reliability of the current location information of the vehicle 12 acquired by the current location information acquisition unit 56 is low, the CPU 30 determines that the reliability of the location information is low. For example, if the location accuracy of the vehicle 12 is output on a five-point scale, the reliability may be determined to be low if it is 2 or less.
[0068] If it is determined in step S108 that the reliability of the location information is low, the CPU 30 ends the image display process. After the vehicle 12 passes through the intersection, the CPU 30 ends the display of the still image M1 and does not display the animation M3.
[0069] On the other hand, if the reliability of the location information is not low in step S108, CPU 30 proceeds to processing in step S110 and determines whether the distance between the closest intersection and the second closest intersection among the intersections to be passed is short. Specifically, CPU 30 acquires the distance between the two intersections to be passed, and if this distance is 95 m or less, determines that the distance between the intersections is short. In this case, CPU 30 proceeds to processing in step S112.
[0070] In step S112, the CPU 30 prohibits the display of the animation M3 of the second intersection, and then the CPU 30 proceeds to the process of step S114.
[0071] On the other hand, if the distance between the intersections is longer than 95 m in step S110, the CPU 30 skips step S112 and proceeds to step S114 to set a virtual line. Specifically, the CPU 30 sets a virtual line connecting the relay points set on the planned travel route. In the example of FIG. 5, the CPU 30 sets a virtual line connecting relay point N1 close to the vehicle 12 to relay point N3 at the intersection. At this time, the CPU 30 sets the virtual line so that it draws a smooth curve at a curved location such as relay point N2.
[0072] In step S116, the CPU 30 determines whether the virtual line is outside the angle of view. Specifically, if at least a portion of the virtual line set in step S112 is outside the range of the angle of view of the display region V3, the CPU 30 determines that the virtual line is outside the angle of view. In this case, the CPU 30 ends the image display process. Furthermore, after the vehicle 12 passes through the intersection, the CPU 30 ends the display of the still image M1 and does not display the animation M3.
[0073] On the other hand, if, in step S116, all of the virtual lines set in step S114 fall within the angle of view of display region V3, CPU 30 proceeds to processing in step S118 and displays animation M3. Specifically, when the distance to the intersection is equal to or less than the second distance, CPU 30 causes the image display unit 60 to project an image from the head-up display device 46 onto display region V3, thereby superimposing and displaying animation M3 in the foreground of display region V3. Then, CPU 30 ends the image display processing.
[0074] As described above, in the vehicle display control system 10 equipped with the vehicle display control device 28 according to this embodiment, the intersection information acquisition unit 54 acquires information about intersections that the vehicle 12 is scheduled to pass through from a predetermined planned driving route of the vehicle 12. Furthermore, when the vehicle 12 approaches an intersection, the image display unit 60 displays an animation M3 showing the vehicle heading toward the intersection superimposed on the foreground in the display area V3 provided in front of the occupant. This allows the occupant to intuitively grasp the location of the intersection.
[0075] Furthermore, if the intersection satisfies a predetermined condition, the image display unit 60 does not display the animation M3. As a result, if displaying the animation M3 would mislead the passengers, the display of the animation is prohibited, thereby preventing the passengers from being confused.
[0076] In particular, in this embodiment, whether or not to display animation M3 is determined based on the classification of the intersection shape, so it is possible to easily determine whether or not to display animation M3 by simply referring to the intersection information acquired by intersection information acquisition unit 54, thereby reducing the processing load on CPU 30.
[0077] In this embodiment, if at least a part of the planned route to the intersection falls outside the viewing angle of the display area and the animation becomes unrecognizable, the animation is not displayed. This prevents the animation from being cut off midway through the intersection, which can confuse the vehicle occupants.
[0078] Furthermore, in this embodiment, when there are consecutive intersections, only the animation M3 for the first intersection is displayed, and the animation for the second intersection is prohibited. This prevents the still image M1 from being displayed momentarily after the vehicle 12 passes through the first intersection, which can confuse the occupants.
[0079] Furthermore, in this embodiment, animation M3 is not displayed when the reliability of the current location information is low, so the animation is not displayed in a direction different from the actual intersection, and passengers are not confused.
[0080] In this embodiment, when the distance to the intersection is equal to or less than a first distance, information about the intersection is displayed as a still image M1, thereby making the occupant aware in advance that they are approaching the intersection. Then, when the distance to the intersection is equal to or less than a second distance, an animation M3 is displayed, allowing the occupant to intuitively grasp the location of the intersection.
[0081] The above describes the vehicle display control system 10, the vehicle display control device 28, and the vehicle 12 according to the embodiment. However, it goes without saying that the present invention can be embodied in various forms without departing from the spirit and scope of the present invention. For example, in the above embodiment, as shown in FIG. 7, the animation M3 is displayed in a generally arrow-like shape, but this is not limited thereto and other shapes may be used. Also, in FIG. 5, the animation M3 is displayed using two arrow-shaped marks, but this is not limited thereto and three or more marks may be displayed, or the animation M3 may be displayed using only one mark.
[0082] In the above embodiment, the intersections with identification numbers 003 to 007 in the table shown in Fig. 4 are determined to be intersections that fall into a predetermined category, but this is not limiting. For example, intersections of other shapes may also be included. For example, a roundabout may also be determined to be an intersection for which animation is not to be displayed.
[0083] Furthermore, in the above embodiment, the animation M3 is not displayed if any one of the following conditions is met: the intersection has an unusual shape, the reliability of the location information is low, or at least a portion of the planned driving route is outside the angle of view of the display area. However, this is not limited to this. For example, the animation M3 may not be displayed only if two or more of the above conditions are met. Also, for example, whether or not to display the animation M3 may be determined based on only one of the above conditions.
[0084] Furthermore, in the above embodiment, a configuration in which information is superimposed on the display area V3 of the third display unit 26 has been described, but the present invention is not limited to this. For example, a configuration in which information is superimposed on the display area V1 of the first display unit 24 or the display area V2 of the second display unit 25 may be adopted. In this case, the information is superimposed on an image of the surroundings of the vehicle 12 captured by a front camera or the like.
[0085] Furthermore, the processing performed by the CPU 30 after reading the program in the above embodiment may be performed by various processors other than the CPU 30. Examples of such processors include dedicated electrical circuits, such as programmable logic devices (PLDs) (such as field-programmable gate arrays (FPGAs)) whose circuit configuration can be changed after fabrication, and application-specific integrated circuits (ASICs) that are processors with circuit configurations specifically designed to perform specific processing. The processing may be performed by one of these various processors, or by a combination of two or more processors of the same or different types, such as multiple FPGAs or a combination of a CPU and an FPGA. The hardware structure of these various processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.
[0086] Furthermore, in the above embodiment, various data is stored in the storage 36, but this is not limiting. For example, a non-transitory recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), or a USB (Universal Serial Bus) memory may be used as the storage unit. In this case, various programs, data, etc. are stored in these recording media.
[0087] Furthermore, the processing flow described in the above embodiment is an example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be changed within the scope of the main idea. [Explanation of symbols]
