[0028] The display control device according to the present invention will be described. The display control device displays a predetermined image in a display area provided on the vehicle, superimposed on or adjacent to a moving object around the vehicle. When the moving object leaves the display area, the display control device changes the appearance of the predetermined image according to the distance between the vehicle and the moving object, and ends the display when a predetermined time has passed since the moving object left the display area.

[0029] [First embodiment] (Overall composition) The overall configuration of a vehicle 12 to which a display control device 10 according to the first embodiment is applied will be described with reference to FIG.

[0030] 1, an instrument panel 16 is provided in the front portion of a passenger compartment 14 of a vehicle 12. The instrument panel 16 extends in the vehicle width direction, and a windshield glass 18 is provided at the front end of the instrument panel 16. The windshield glass 18 extends from the front end of the instrument panel 16 toward the upper side of the vehicle, and separates the interior of the passenger compartment 14 of the vehicle 12 from the outside.

[0031] A head-up display (hereinafter referred to as "HUD") projection surface 20 having a display area 20A is provided on the windshield glass 18 above the vehicle meter display 22. The HUD projection surface 20 is a projection surface onto which an image is projected by a HUD device 21. Specifically, the HUD device 21 is provided on the vehicle front side of the instrument panel 16, and an image is projected from the HUD device 21 onto the HUD projection surface 20 on the windshield glass 18. In other words, the HUD projection surface 20 is part of the windshield glass 18.

[0032] The instrument panel 16 is provided with a meter display 22 having a display area 22A. The meter display 22 is provided on the right side of the instrument panel 16 in the vehicle width direction, in front of the driver's seat. The meter display 22 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.

[0033] A center display 24 having a display area 24A is provided on the instrument panel 16. The center display 24 is disposed in the center of the instrument panel 16 in the vehicle width direction.

[0034] (Hardware configuration of the display control device 10) The hardware configuration of the display control device 10 provided in the vehicle 12 will be described with reference to Fig. 2. The display control device 10 of this embodiment is configured to include an ECU (Electronic Control Unit) 26. Note that although this embodiment illustrates an example in which processing is performed by one ECU, a configuration in which multiple ECUs are provided and processing is performed across the multiple ECUs may also be adopted.

[0035] 2, the ECU 26 of the display control device 10 includes a CPU (Central Processing Unit: processor) 28, a ROM (Read Only Memory) 30, a RAM (Random Access Memory) 32, a storage 34, a communication interface (communication I / F) 36, and an input / output interface (input / output I / F) 38. Each component is connected to each other via a bus 40 so as to be able to communicate with each other.

[0036] The CPU 28 is a central processing unit that executes various programs and controls each part. That is, the CPU 28 reads a program from the ROM 30 or the storage 34 and executes the program using the RAM 32 as a work area.

[0037] The ROM 30 stores various programs and various data. The RAM 32 temporarily stores programs or data as a working area. The storage 34 is configured with an HDD (Hard Disk Drive) or an SSD (Solid State Drive) and stores various programs including an operating system and various data. In this embodiment, the ROM 30 or the storage 34 stores programs for performing display processing, various data, and the like.

[0038] Each program may be provided in a form recorded on a non-transitory recording medium such as a CD-ROM (Compact Disc Read Only Memory), a DVD-ROM (Digital Versatile Disc Read Only Memory), or a USB (Universal Serial Bus) memory. Also, the program may be downloaded from an external device via a network.

[0039] The input / output I / F 38 is connected to the HUD device 21, the meter display 22, the center display 24, and the sensor unit 42. The HUD device 21 projects an image onto the HUD projection surface 20.

[0040] The communication I / F 36 is an interface for the display control device 10 to communicate with a server and other devices (not shown), and uses standards such as Ethernet (registered trademark), LTE, FDDI, and Wi-Fi (registered trademark).

[0041] The sensor unit 42 includes a plurality of sensors selected from various sensors such as a camera, radar, lidar, GPS sensor, etc. In particular, the camera of this embodiment is configured to capture images of the periphery of the vehicle 12 and to include at least a front camera that captures images of the area ahead of the vehicle.

[0042] The vehicle 12 is also provided with a sensor unit 42 or a driving assistance unit capable of communicating with the sensor unit 42, which executes a plurality of driving assistance applications, and performs arithmetic processing based on information from the plurality of sensors. Examples of the driving assistance applications include collision avoidance control and adaptive cruise control (ACC). The ECU 26 can acquire information from the driving assistance applications and sensors via the input / output I / F 38.

[0043] (Functional configuration of the display control device 10) The functional configuration realized by the display control device 10 using the above hardware resources will be described with reference to FIG. 3 and FIGS. 4A to 4C.

[0044] 3, the ECU 26 of the display control device 10 includes, as functional components, an acquisition unit 26A and a control unit 26B. Each functional component is realized by the CPU 28 reading and executing a program stored in the ROM 30 or the storage 34.

[0045] The acquisition unit 26A acquires information about moving objects around the vehicle. Specifically, the acquisition unit 26A acquires information about the position of a leading vehicle 44 traveling ahead of the vehicle 12. For example, the acquisition unit 26A acquires captured image data of the area ahead of the vehicle captured by a front camera, and detects coordinate data of the leading vehicle 44 based on the acquired captured image data of the leading vehicle 44. Note that in this embodiment, the leading vehicle 44 is described as an example of a moving object, but the moving object may be another traffic participant such as a motorcycle or a bicycle. In that case, information about the type of moving object can be acquired from a driving assistance unit that executes multiple driving assistance applications.

[0046] The control unit 26B detects whether the leading vehicle 44 has moved out of the display area 20A of the HUD projection surface 20 based on the information about the position of the leading vehicle 44 acquired by the acquisition unit 26A. Specifically, as an example, position coordinates corresponding to the display area 20A are set in advance, and the control unit 26B determines whether the coordinate data of the leading vehicle 44 acquired by the acquisition unit 26A is inside or outside the display area 20A. If the leading vehicle 44 is outside the display area 20A, the control unit 26B detects that the leading vehicle 44 has moved out of the display area 20A of the HUD projection surface 20.

[0047] Furthermore, the control unit 26B generates images to be displayed on the HUD projection surface 20. The images generated by the control unit 26B include, in addition to the marker 46 as a predetermined image, for example, a meter image showing a meter display indicating the traveling speed of the vehicle 12, and various images intended to assist manual driving and automatic driving.

[0048] Furthermore, when the leading vehicle 44 is located within the display area 20A, the control unit 26B displays a marker 46 adjacent to the leading vehicle 44 in the display area 20A provided on the vehicle 12 according to the position of the leading vehicle 44 based on the acquired information about the leading vehicle 44. In particular, in this embodiment, when the ACC is activated, the linear marker 46 is displayed adjacent to the rear end of the leading vehicle 44 that is being followed. FIG. 4A is a diagram showing a state in which the ACC is activated and the marker 46 is displayed. FIG. 4B is a diagram showing a state in which the leading vehicle 44 is traveling faster than the vehicle 12 and is therefore further away from the vehicle 12 than in the state of FIG. 4A. FIG. 4C is a diagram showing a state in which the leading vehicle 44 continues to travel faster than the vehicle 12 and is therefore further away from the vehicle 12 than in the state of FIG. 4B.

[0049] Furthermore, when the leading vehicle 44 moves away from the vehicle 12 and thus moves out of the display area 20A, the control unit 26B continues to display the marker 46 until a predetermined time has passed since the leading vehicle 44 moved out of the display area 20A. In particular, in this embodiment, as shown in Fig. 4C, when the leading vehicle 44 moves out of the display area 20A, the control unit 26B displays the marker 46 at the position where it moved out for a predetermined time, and stops displaying the marker 46 after the predetermined time has passed.

[0050] By having control unit 26B display marker 46 for a predetermined time, it is possible to reduce the risk of the driver feeling uneasy when the superimposed display suddenly disappears if the preceding vehicle leaves the display area. Also, when the preceding vehicle (i.e., preceding vehicle 44) repeatedly enters and leaves the display area, the superimposed display is repeatedly displayed and hidden, which can reduce the risk of the display becoming cumbersome. Furthermore, by ending the display of marker 46 after the predetermined time has elapsed, it is possible to reduce the risk of the driver feeling uncomfortable as a result of the superimposed display being continued in a situation where it cannot be displayed in accordance with the preceding vehicle.

[0051] In this embodiment, the marker 46 continues to be displayed while the ACC is activated. However, the marker 46 may be displayed only for a predetermined period after the ACC is activated, even if the preceding vehicle 44 is present in the display area 20A. In the case where the marker 46 is displayed only for a predetermined period after the ACC is activated, the above control is performed if the preceding vehicle 44 leaves the display area 20A within the predetermined period. The marker 46 may be, for example, an image of any shape, and may be superimposed on the entire preceding vehicle 44. The shape of the marker 46 may also be selected based on the type of moving object.

[0052] Note that the control unit 26B may be configured to suppress the display of the marker 46 when the preceding vehicle 44 moves away from the vehicle 12 and thus moves out of the display area 20A, and the distance between the vehicle 12 and the preceding vehicle 44 becomes a predetermined distance. Even in this case, the marker 46 does not suddenly disappear even when the preceding vehicle 44 moves out of the display area 20A, so it is possible to suppress the sense of discomfort felt by the occupants.

[0053] (Flow of Control) The flow of processing executed by the display control device 10 of this embodiment will be described using the flowchart in Fig. 5 and examples of displays related to the marker 46 in Fig. 4A to Fig. 4C. The processing in the display control device 10 is executed by the ECU 26 functioning as an acquisition unit 26A and a control unit 26B.

[0054] In step S100, the ECU 26 acquires information about the driving assistance application through the input / output I / F 38. In particular, in this embodiment, information about the ACC and information about the following preceding vehicle 44 is acquired. This information includes, for example, a signal indicating whether the ACC is operating, information about the distance to the preceding vehicle 44, information about the coordinates of the preceding vehicle 44, and the like.

[0055] In step S102, the ECU 26 determines whether the ACC is operating. If the determination is negative (NO in step S102), the ECU 26 ends the flow. On the other hand, if the determination is positive (YES in step S102), the ECU 26 proceeds to step S104.

[0056] In step S104, based on the acquired information, ECU 26 displays marker 46 adjacent to the rear end of leading vehicle 44. That is, as shown in FIG. 4A, marker 46 is displayed adjacent to the bottom edge of the real image of leading vehicle 44 in display area 20A.

[0057] In step S106, the ECU 26 determines whether the preceding vehicle 44 has left the display area 20A. If the determination is negative (NO in step S106), the ECU 26 returns to step S104 and continues to display the marker 46. On the other hand, if the determination is positive (YES in step S106), the ECU 26 proceeds to step S108.

[0058] In step S108, the ECU 26 changes the state of the marker 46 depending on the position of the leading vehicle 44. For example, the ECU 26 may display the marker 46 with a lower brightness as the distance between the leading vehicle 44 and the vehicle 12 increases, or may display the marker 46 with a lighter color as the distance between the leading vehicle 44 and the vehicle 12 increases.

[0059] In step S110, the ECU 26 determines whether a predetermined time has elapsed since the preceding vehicle 44 left the display area 20 A. If the determination is negative (NO in step S110), the ECU 26 returns to step S106, and if the determination is affirmative (YES in step S110), the ECU 26 proceeds to step S112.

[0060] In step S112, the ECU 26 erases the marker 46, which has been displayed adjacent to the rear end of the leading vehicle 44, from the display area 20A. For example, the marker 46 may be gradually erased from the display area 20A, or the marker 46 may flash multiple times before being erased from the display area 20A. The gradual erasure may be achieved by gradually decreasing the brightness or gradually increasing the transparency.

[0061] In another aspect, for example, the ECU 26 may display the marker 48A smaller as the distance between the leading vehicle 44 and the vehicle 12 increases. Explaining this with reference to FIGS. 6A, 6B, and 6C, the distance between the leading vehicle 44 and the vehicle 12 increases in the order of FIGS. 6A to 6C, and the images of the markers 48A, 48B, and 48C become smaller in this order. By displaying the marker 48A smaller as the distance between the leading vehicle 44 and the vehicle 12 increases, it becomes easier to grasp the sense of distance to the leading vehicle 44 as a moving object, and it is possible to further reduce the driver's sense of discomfort. In this aspect, the markers 48A, 48B, and 48C are examples of predetermined images.

[0062] In yet another aspect, for example, the ECU 26 may display a broken line with a bent portion protruding upward in the display area 20A adjacent to the rear end of the leading vehicle 44. In this case, the greater the distance between the leading vehicle 44 and the vehicle 12, the smaller the displayed inferior angle of the bent portion. Referring to FIGS. 7A, 7B, and 7C, the distance between the leading vehicle 44 and the vehicle 12 increases in the order of FIGS. 7A, 7B, and 7C, and the inferior angle of the bent portion decreases in the order of marker 50A, marker 50B, and marker 50C. By displaying the inferior angle of the bent portion smaller as the distance between the leading vehicle 44 and the vehicle 12 increases, the driver can more easily grasp the sense of distance from the leading vehicle 44, thereby further reducing the sense of discomfort felt by the driver. In this aspect, the markers 50A, 50B, and 50C are examples of predetermined images.

[0063] [Second embodiment] In the above embodiment, the display area 20A is configured by the HUD projection surface 20, but the present invention is not limited to this. As in a second embodiment shown in FIG. 8, the marker 46 may be displayed in the display area of ​​the center display 24 provided on the instrument panel 16.

[0064] 8, in the second embodiment, the display area 24A of the center display 24 is divided into upper and lower halves. An upper portion 52 of the display area 24A displays a foreground image showing the foreground of the vehicle 12, and a lower portion 54 of the display area 24A displays a map image M showing the current position of the vehicle 12.

[0065] The foreground image is configured, for example, by a captured image captured by a front camera constituting the sensor unit 42. Unlike the first embodiment, in the second embodiment, when the leading vehicle 44 moves out of the upper part 52 of the display area 24A, that is, when the leading vehicle 44 is no longer present within the angle of view of the captured image displayed in the upper part 52 of the display area 24A, a marker 46 is displayed for a predetermined time at the position in the upper part 52 of the display area 24A where the leading vehicle 44 moves out (the edge of the display area 24A).

[0066] In the second embodiment, a marker 46 is displayed on the center display 24 provided on the instrument panel 16, and when the preceding vehicle 44 moves out of the upper portion 52 of the display area 24A, the marker 46 is displayed for a predetermined time at the position in the display area 24A where the preceding vehicle 44 moves out (at the edge of the display area 24A). This makes it possible to prevent the driver from feeling uncomfortable when viewing the center display 24, regardless of the seating position, as in the first embodiment.

[0067] [Third embodiment] In the third embodiment, a captured image captured by the front camera constituting the sensor unit 42 and a marker 46 are displayed in a display area 22A of a meter display 22 provided in front of the driver's seat. Because the meter display 22 is provided in front of the driver's seat, the occupant in the driver's seat can view the meter display 22 without moving their line of sight from the foreground of the vehicle.

[0068] [remarks] In the above embodiment, various processes executed by the CPU 28 after reading software (programs) may be executed by various processors other than a CPU. Examples of such processors include 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 dedicated electrical circuits designed specifically to execute specific processes. Each of the above processes may be executed by one of these processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, or a combination of a CPU and an FPGA). The hardware structure of these processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.

[0069] Although the embodiments of the present invention have been described above, the present invention is not limited to the above examples and various modifications are possible. For example, the processing flow described in the above embodiments is an example, and unnecessary steps may be deleted, new steps may be added, or the processing order may be changed, without departing from the scope of the present invention.
