[0003] [Patent Document 1] Japanese Patent Publication No. 2022-41244 Summary of the Invention [Problem to be solved by the invention]

[0004] Now, consider a situation where an image simulating a curved road (hereinafter simply referred to as a "curved road") is displayed on a display unit inside the vehicle when the road is traveled on a curved road. In this case, even if an image approximating the curvature of an actual curved road is displayed on a display unit inside the vehicle, the appearance of the curved road varies depending on the occupant, and the occupant of the vehicle may feel uncomfortable.

[0005] The in-vehicle display device disclosed in Patent Document 1 suppresses the display of images of surrounding objects other than a first preceding vehicle traveling ahead in the lane in which the vehicle is traveling on a head-up display, while displaying the first preceding vehicle on a meter display and displaying the other surrounding objects in gradually toned-down colors according to their importance.

[0006] However, Patent Document 1 does not take into consideration changing the curvature of a curved road drawn on an image that simulates a road.

[0007] The present invention aims to provide a vehicle display control device, a vehicle display control method, and a vehicle display control program that reduce the discomfort felt by occupants of a vehicle when an image showing the surrounding situation of the vehicle is presented to the occupants when the vehicle is traveling on a curved road. [Means for solving the problem]

[0008] The vehicle control device according to the first aspect is a display control device for a vehicle that includes an acquisition unit that acquires driving history data of the vehicle, and a display control unit that, when the road on which the vehicle is traveling is a curved road, changes the stage of change in curvature of the curved road depicted in an image that resembles the road in accordance with the driving history data, and displays, on a display unit, an image that resembles the road that corresponds to the curved road on which the vehicle is traveling, among the changed stages.

[0009] A vehicle control device according to a first aspect acquires driving history data of a host vehicle. When the driving path on which the host vehicle is traveling is a curved path, the vehicle control device changes the stage of change in curvature of the curved path depicted in an image simulating the driving path according to the driving history data, and displays, on a display unit, an image simulating the driving path corresponding to the curved path on which the host vehicle is traveling, among the changed stages, together with an image simulating the host vehicle. This reduces the discomfort felt by the occupants of the host vehicle when an image showing the surrounding conditions of the host vehicle is presented to the occupants while the vehicle is traveling on a curved path.

[0010] In a vehicle control device according to a second aspect, in the vehicle control device according to the first aspect, the driving history data is history data of steering operations of the driver of the host vehicle, and the display control unit changes the stage of change in the curvature based on the history data of the steering operations, thereby making it possible to reproduce the curvature of a curved road according to the speed of the steering operation of the driver of the host vehicle.

[0011] A vehicle control device according to a third aspect is the vehicle control device according to the first to second aspects, wherein the driving history data is history data of a road on which the host vehicle has traveled, and the display control unit changes the stage of change in curvature based on the history data of the road, thereby making it possible to reproduce the curvature of a curved road according to the driving history of the host vehicle.

[0012] A fourth aspect of the present invention relates to a vehicle display control method, in which a computer executes a process to acquire driving history data of a host vehicle, and, when the host vehicle is traveling on a curved road, change a stage of change in curvature of the curved road depicted in an image simulating the road in accordance with the driving history data, and display, on a display unit, an image simulating the road that corresponds to the curved road on which the host vehicle is traveling, among the changed stages, together with an image simulating the host vehicle. This makes it possible to reduce the discomfort felt by the occupants of the host vehicle when an image representing the surrounding situation of the host vehicle is presented to the occupants while the vehicle is traveling on a curved road.

[0013] A vehicle display control program according to a fifth aspect is a vehicle display control program for causing a computer to execute a process of acquiring driving history data of a host vehicle, changing a stage of change in curvature of the curved road depicted in an image simulating the road in accordance with the driving history data when the road on which the host vehicle is traveling is a curved road, and displaying, on a display unit, an image simulating the road that corresponds to the changed stage of the curved road on which the host vehicle is traveling, together with an image simulating the host vehicle. This makes it possible to reduce the discomfort felt by the occupants of the host vehicle when an image representing the surrounding situation of the host vehicle is presented to the occupants while the vehicle is traveling on a curved road. [Effects of the Invention]

[0016] First Embodiment Fig. 1 is a schematic configuration diagram of a vehicle display control system 10 according to a first embodiment. As shown in Fig. 1, the vehicle display control system 10 is mounted on a vehicle 12. Also, as shown in Fig. 1, the vehicle display control system 10 includes a camera 14, a radar device 15, a steering angle sensor 16, a display device 17, and a vehicle display control device 20.

[0017] The camera 14 captures images of the surroundings of the vehicle and outputs the captured images.

[0018] The radar device 15 detects various objects such as surrounding vehicles present around the vehicle 12 as point cloud information.

[0019] The steering angle sensor 16 detects the steering angle θ of the vehicle 12 when the vehicle is steered.

[0020] The display device 17, which is an example of a display unit, is, for example, a meter display, a head-up display, or a car navigation display.

[0021] The vehicular display control device 20 is, for example, an ECU (Electronic Control Unit) that performs various controls. The vehicular display control device 20 displays an image showing the surrounding situation of the vehicle as seen from a virtual viewpoint on a display device 17 located near the driver's seat.

[0022] (Hardware configuration of the vehicle display control device 20) 1, the vehicle display control device 20 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.

[0023] 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.

[0024] 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 vehicle display control program for performing display processing and the like.

[0025] The communication interface 38 is an interface that enables the vehicle display control device 20 to communicate with a server and other devices, and is realized according to a technology using standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), or Wi-Fi (registered trademark).

[0026] The input / output interface 40 is connected to a camera 14 , a radar device 15 , a steering angle sensor 16 , and a display device 17 .

[0027] (Functional configuration of the vehicle display control device 20) The vehicular display control device 20 uses the above hardware resources to realize various functions. The functional configuration realized by the vehicular display control device 20 will be described with reference to FIG.

[0028] 2, the vehicle display control device 20 includes, as functional components, an acquisition unit 280, a display control unit 282, and a driving history data storage unit 284. Each functional component is realized by the CPU 30 reading and executing a program stored in the ROM 32 or the storage 36.

[0029] The acquisition unit 280 acquires the image captured by the camera 14 , the point cloud information detected by the radar device 15 , and the steering angle θ acquired by the steering angle sensor 16 .

[0030] The display control unit 282 generates an image representing the surrounding situation of the vehicle 12 based on the surrounding information including the image and point cloud information acquired by the acquisition unit 280. Then, the display control unit 282 causes the display device 17 to display the image representing the surrounding situation of the vehicle 12.

[0031] Fig. 3 is a diagram showing an example of an image showing the surrounding conditions of the host vehicle 12, displayed on the display device 17. As shown in Fig. 3, image 58 displays an image 64 that resembles the host vehicle, an image 66 that resembles the road on which the host vehicle is traveling, and images 70 and 72 that resemble surrounding vehicles present around the host vehicle. Note that, hereinafter, the image that resembles the road will be simply referred to as a "road image."

[0032] If the road on which the vehicle 12 is actually traveling is a curved road, the curved road is also depicted in the road image 66, as shown in Fig. 3. Whether the actual road is a curved road and its curvature can be obtained, for example, by processing the image captured by the camera 14 or the point cloud information acquired by the radar device 15 using a known method.

[0033] FIG. 4 is a diagram showing an example of a roadway image when representing a straight road and a curved road. The roadway image S in FIG. 4 represents that the roadway is a straight road. Furthermore, the roadway images C1 to C3 in FIG. 4 represent that the roadway is a curved road. The curvature of the curved road depicted in the roadway image C1, the curvature of the curved road depicted in the roadway image C2, and the curvature of the curved road depicted in the roadway image C3 are different. Note that the larger the curvature R, the gentler the degree of curvature of the curved road, and the smaller the curvature R, the sharper the degree of curvature of the curved road. Therefore, the curvature of the curved road depicted in the roadway image C1 is large, the curvature of the curved road depicted in the roadway image C2 is medium, and the curvature of the curved road depicted in the roadway image C3 is small. Note that while FIG. 4 shows an image of a roadway curving left, images of roadways curving right are also prepared in advance.

[0034] FIG. 5 is a diagram for explaining the change in the stage of change of curvature R. As shown in FIG. 5(A), in this embodiment, the curvature of the curved road drawn on the travel road image is changed in stages according to the curvature R of the actual curved road. In the example shown in FIG. 5(A), if the actual curved road is a left curve and its curvature R is 1200 m or more, the straight travel road image S of FIG. 4 is displayed on the display device 17. If the curvature R of the actual curved road is 800 m or more and less than 1200 m, the travel road image C1 of FIG. 4 is displayed on the display device 17. If the curvature R of the actual curved road is 400 m or more and less than 800 m, the travel road image C2 of FIG. 4 is displayed on the display device 17. If the curvature R of the actual curved road is 200 m or more and less than 400 m, the travel road image C3 of FIG. 4 is displayed on the display device 17.

[0035] However, since the way a curved road is perceived varies depending on the occupant, even if the road image is displayed on the display device 17 with gradually changing curvature as shown in Figure 5, the occupant of the vehicle may feel uncomfortable.

[0036] Therefore, in this embodiment, the stage of change of the curved road is changed based on driving history data that represents the driving history of the vehicle 12. For example, even when driving a vehicle on the same curved road, there are drivers who drive the vehicle by turning the steering wheel slowly and drivers who drive the vehicle by turning the steering wheel abruptly. For this reason, the vehicle display control device 20 of the first embodiment learns the driving operation habits of the driver and changes the stage of change of the curvature of the curved road drawn in the road image according to the learning results.

[0037] Specifically, the vehicle display control device 20 of the first embodiment is capable of displaying on the display device 17 a roadway image depicting a gently curved road for a driver who drives the vehicle 12 by gently turning the steering wheel, and is capable of displaying on the display device 17 a roadway image depicting a sharply curved road for a driver who drives the vehicle 12 by rapidly turning the steering wheel.

[0038] 5(A), for example, the curvature changes in three stages, and when the road is a curved road, one of road image C1, road image C2, and road image C3 is displayed on the display device 17. In contrast, for example, the vehicle display control device 20 of the first embodiment increases the number of stages of change in curvature of the curved road depicted in the road image to five stages for an occupant who drives the vehicle 12 by turning the steering wheel suddenly.

[0039] In this case, for example, a new roadway image expressing a curvature between the curvature expressed in roadway image C1 and the curvature expressed in roadway image C2, and a new roadway image expressing a curvature between the curvature expressed in roadway image C2 and the curvature expressed in roadway image C3 are prepared, and one of these roadway images is displayed on display device 17 according to the curvature of the actual curved road. Alternatively, for example, a roadway image expressing a curved road with a smaller curvature corresponding to the curved road with a curvature R of less than 200 shown in Fig. 5(A) may be prepared, and one of these roadway images may be displayed on display device 17 according to the curvature of the actual curved road.

[0040] Furthermore, for example, the vehicle display control device 20 of the first embodiment reduces the number of stages of curvature change for a driver who drives the vehicle 12 by turning the steering wheel slowly. For example, if the curvature change is five stages, the change in curvature R is reduced to three stages. Alternatively, for example, road images depicting curved roads with larger curvatures, such as those corresponding to the curved roads with curvature R of 1200 or more shown in FIG. 5(A), may be prepared, and one of these road images may be displayed on the display device 17 depending on the curvature of the actual curved road.

[0041] This reduces the sense of discomfort felt by the driver, who is an occupant. Specifically, it is assumed that a driver who drives the vehicle 12 by making sudden steering turns will frequently recognize a curved road with sharp turns. On the other hand, it is assumed that a driver who drives the vehicle 12 by making gentle steering turns will frequently recognize a curved road with gentle turns. For this reason, by displaying a road image with an increased or decreased number of stages of curvature change in response to steering operation, the sense of discomfort felt by the driver is reduced.

[0042] The driving history data storage unit 284 sequentially stores driving history data of the driver of the host vehicle 12. Specifically, the driving history data in the first embodiment is history data of steering operations of the driver of the host vehicle 12. Therefore, the driving history data storage unit 284 stores steering operation history data obtained from the steering angle θ acquired by the acquisition unit 280. The steering operation history data is, for example, the amount of change in the steering angle θ within a predetermined time when a curved road is detected ahead of the host vehicle 12. Depending on the magnitude of the amount of change in the steering angle θ, it is possible to determine whether the driver's steering operation is sudden or gradual. Whether a curved road exists ahead of the host vehicle 12 is detected based on the image captured by the camera 14 and the point cloud information detected by the radar device 15.

[0043] The acquisition unit 280 acquires the driving history data of the vehicle 12 stored in the driving history data storage unit 284. When there are multiple drivers driving the vehicle 12, the acquisition unit 280 may identify the driver and acquire the driving history data based on, for example, a facial image of the driver captured by a driver monitor (not shown) installed in the vehicle 12 or information stored in a seat memory (not shown).

[0044] Next, the display control unit 282 causes the display device 17 to display an image simulating the host vehicle 12 and a road image as viewed from a virtual viewpoint. At this time, if the road on which the host vehicle 12 is traveling is curved, the display control unit 282 changes the level of change in curvature of the curved road depicted in the road image according to the driving history data acquired by the acquisition unit 280. The display control unit 282 calculates the curvature R of the road on which the host vehicle 12 is traveling (e.g., the road ahead of the host vehicle 12) and determines whether the road on which the host vehicle 12 is traveling is curved. Furthermore, if the amount of change in steering operation represented by the driving history data is large (e.g., equal to or greater than a predetermined first threshold), the display control unit 282 increases the level of change in curvature. On the other hand, if the amount of change in steering operation represented by the driving history data is small (e.g., equal to or less than a predetermined second threshold), the display control unit 282 decreases the level of change in curvature.

[0045] Then, based on the stage of change in curvature set above, the display control unit 282 causes the display device 17 to display a road image corresponding to the curvature of the actual curved road. Specifically, the display control unit 282 causes the display device 17 to display a road image corresponding to the curved road on which the host vehicle 12 is traveling, among the stages in which the stage of change in curvature has been changed, together with an image that resembles the host vehicle 12.

[0046] (action) Next, the operation of the vehicle display control system 10 of this embodiment will be described.

[0047] (Vehicle display control processing) The vehicular display control device 20 executes a vehicular display control processing routine shown in Fig. 6. This vehicular display control processing is executed by the CPU 30 reading out a vehicular display control program from the ROM 32 or the storage 36, expanding the program into the RAM 34, and executing the program.

[0048] In step S100, the acquisition unit 280 acquires steering operation history data, which is driving history data stored in the driving history data storage unit 284.

[0049] In step S102, the display control unit 282 changes the stage of change in curvature of the curved road depicted in the road image, depending on the steering operation history data, which is the driving history data acquired in step S100. For example, the display control unit 282 increases or decreases the stage of change in curvature of the curved road, depending on the steering operation history data.

[0050] In step S104, the display control unit 282 acquires peripheral information about the vehicle 12, including the image captured by the camera 14 and the point cloud information detected by the radar device 15. The display control unit 282 also calculates the curvature R of the road ahead of the vehicle 12 based on the peripheral information.

[0051] In step S106, the display control unit 282 determines whether or not a curved road exists ahead of the host vehicle 12, based on the curvature R of the road ahead of the host vehicle 12 calculated in step S104. The display control unit 282 determines whether or not a curved road exists ahead of the host vehicle 12 by threshold processing the curvature R of the road ahead of the host vehicle 12 calculated in step S104. If no curved road exists ahead of the host vehicle 12, the process proceeds to step S107. On the other hand, if a curved road exists ahead of the host vehicle 12, the process proceeds to step S108.

[0052] In step S107, the display control unit 282 causes the display device 17 to display a road image in which the road is represented by straight lines. For example, the road image S shown in FIG.

[0053] In step S108, the display control unit 282 selects a road image of a curved road that corresponds to the stage of change in curvature changed in step S102. For example, as shown in Fig. 5(A), when the curvature R of the curved road ahead of the vehicle 12 calculated in step S104 is R = 600, the road image C2 is selected.

[0054] In step S110, the display control unit 282 causes the display device 17 to display the road image selected in step S108.

[0055] As described above, the vehicle display control device of the first embodiment acquires driving history data of the host vehicle. The vehicle display control device displays, on a display device, an image of the host vehicle and a driving road image as viewed from a virtual viewpoint. When the driving road on which the host vehicle is traveling is curved, the vehicle display control device changes the stage of change in curved road curvature depicted on the driving road image according to the driving history data. The vehicle display control device then displays, on the display device, a driving road image corresponding to the curved road on which the host vehicle is traveling, among the changed stages. This reduces the discomfort felt by the occupants of the host vehicle when an image showing the surrounding conditions of the host vehicle is presented to the occupants while the vehicle is traveling on a curved road.

[0056] Second Embodiment Next, a second embodiment will be described. The driving history data of the second embodiment is history data of the roads on which the vehicle has traveled, and the vehicle display control system of the second embodiment differs from the first embodiment in that it changes the stage of change in curvature of a curved road based on the history data of the road. Note that the configuration of the vehicle display control system of the second embodiment is similar to that of the vehicle display control system 10 of the first embodiment, and therefore a description thereof will be omitted.

[0057] The vehicle display control device of the second embodiment learns what types of roads the host vehicle 12 frequently travels on and changes the stage of change in curvature of a curved road based on the learning results. Therefore, the driving history data in the second embodiment is history data of roads traveled by the host vehicle 12. The history data of roads is collected, for example, based on images captured by the camera 14 and point cloud information detected by the radar device 15 while the host vehicle 12 is traveling. Specifically, the curvature R of the curved roads actually traveled by the host vehicle 12 is acquired by analyzing the images captured by the camera 14 and the point cloud information detected by the radar device 15 using a known method, and the curvature R is stored in the driving history data storage unit 284. Alternatively, the curvature R of the curved roads actually traveled by the host vehicle 12 is acquired based on position information acquired by a GPS device mounted on the host vehicle 12 and map data reflecting information on the curvature of the curved road, and the curvature R is stored in the driving history data storage unit 284.

[0058] For example, consider a case where the historical data of the curvature R of curved roads that the vehicle 12 has actually traveled indicates that the frequency of curved roads with R=700 m and the frequency of curved roads with R=500 m are high. In this case, the display control unit 282 changes the stage of change in curvature shown in FIG. 5(A) to the stage of change in curvature shown in FIG. 5(B) so that the two curved roads can be distinguished. As a result, the image of a road with R=700 m and the image of a road with R=500 m, which the vehicle 12 usually travels on, are adjusted to be different images. As a result, the curved road with R=700 m and the curved road with R=500 m can be distinguished on the display device 17, reducing the sense of discomfort felt by the occupants.

[0059] Alternatively, for example, consider a case where the historical data on the curvature R of curved roads that the vehicle 12 has actually traveled indicates that the frequency of curved roads with R=600 m, R=400 m, and R=250 m is high. In this case, the display control unit 282 increases the number of stages of curvature change to four, as shown in FIG. 5(C), so that the three curved roads can be distinguished. In this case, a new road image X is prepared, as shown in FIG. 5(C). This makes it possible to distinguish on the display device 17 the curved roads with R=600 m, R=400 m, and R=250 m, which the vehicle 12 usually travels on frequently, and reduces the sense of discomfort felt by the occupants.

[0060] As described above, the vehicle display control device of the second embodiment changes the stage of change in curved road curvature based on the history data of the road on which the host vehicle has traveled. This reduces the sense of discomfort felt by the occupants of the host vehicle. Specifically, the occupants of the host vehicle 12 can distinguish between curved roads on which the host vehicle 12 normally travels, thereby reducing the sense of discomfort felt when viewing the road image.

[0061] Although the vehicle display control system 10 according to each embodiment has been described above, 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.

[0062] For example, the processing executed by the CPU 30 after reading the program in the above embodiment may be executed by various processors other than the CPU 30. Examples of such processors include programmable logic devices (PLDs) whose circuit configuration can be changed after fabrication, such as field-programmable gate arrays (FPGAs), and dedicated electrical circuits, such as application-specific integrated circuits (ASICs), which are processors having a circuit configuration specifically designed to execute specific processing. Furthermore, the processing may be executed 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. Furthermore, the hardware structure of these various processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.

[0063] 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 and data are stored in these recording media.

[0064] 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 gist. [Explanation of symbols]
