[Technical Field]

[0001] The present disclosure relates to a display control device, a display control method, and a program. [Background technology]

[0002] In recent vehicles, drivers not only drive manually but also sometimes receive assistance with various operations from advanced driver-assistance systems (ADAS), etc. There are various types of driving assistance, but the details of the driving assistance being implemented are generally communicated to the driver via a display device such as a monitor inside the vehicle.

[0003] The following Patent Document 1 describes a display device that displays behavior information showing the behavior of a vehicle over time based on operation history information of driving assistance by a driving assistance system and driving history information of the vehicle. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-139186 Summary of the Invention [Problem to be solved by the invention]

[0005] Various driving assistance systems are known. Specific examples include deceleration assistance that assists only with deceleration operations when specific conditions are met, and adaptive cruise control (ACC) that includes acceleration and deceleration assistance for following a preceding vehicle at a predetermined distance. The deceleration assistance and ACC described above differ in the scope of their assistance. On the other hand, the deceleration assistance and deceleration assistance performed during ACC operation are assistance operations that are generally recognized by the driver as the same control behavior, although there are differences in the detailed conditions, etc. Therefore, when displaying these functions, it is important to clearly inform the vehicle occupants, particularly the driver, of the functions, including the assistance content, at a glance, in order to prevent the driver from misunderstanding the assistance content, etc.

[0006] In view of the above-mentioned problems, the present disclosure aims to provide a display control device, a display control method, and a program that can inform occupants of information related to deceleration assistance in an easy-to-understand manner. [Means for solving the problem]

[0010] In the display control device according to claim 2, the deceleration support image itself is not changed, so there is no need to prepare multiple types of deceleration support images according to the exercise support mode currently being operated.

[0011] The display control device according to claim 3 of the present disclosure is a display control device according to claim 1 or claim 2, wherein the driving assistance modes include a deceleration assistance mode that only provides deceleration assistance, and an adaptive cruise control mode that includes acceleration / deceleration assistance for following a preceding vehicle at a fixed interval.

[0012] In the display control device according to claim 3, deceleration support images that represent deceleration support in different modes can be distinguished at a glance.

[0013] The display control device according to claim 4 of the present disclosure is the display control device according to claim 3 above, wherein the driving assistance mode further includes a congestion following mode that includes acceleration / deceleration assistance for following a preceding vehicle at a fixed interval when congestion occurs.

[0014] In the display control device according to claim 4, deceleration support images that represent deceleration support in different modes can be distinguished at a glance.

[0015] A display control device according to claim 5 of the present disclosure is the display control device according to any one of claims 1 to 4, wherein the deceleration support image is an icon representing an event requiring deceleration support.

[0016] In the display control device according to claim 5, by using icons as images, it becomes easier for the user to immediately grasp the meaning of the images.

[0018] In the display control method of claim 6, the display format of the deceleration support image is adjusted to correspond to the display format of the driving mode image before being displayed, so that the driving support mode in operation can be understood simply by looking at the deceleration support image.

[0019] The program according to claim 7 of the present disclosure causes a processor constituting a computer to execute the following processes: displaying a driving mode image corresponding to the driving assistance mode of the vehicle on a display device provided in the vehicle; adjusting the display format of the deceleration assistance image to a display format corresponding to the display format of the driving mode image when performing deceleration assistance; and displaying the adjusted deceleration assistance image together with the driving mode image.

[0020] In the program of claim 7, the display format of the deceleration support image is adjusted to correspond to the display format of the driving mode image before being displayed, so that the driving support mode in operation can be understood simply by looking at the deceleration support image. [Effects of the Invention]

[0023] Hereinafter, each embodiment for carrying out the present disclosure will be described with reference to the drawings. Note that the scope necessary for the explanation to achieve the object of the present disclosure will be schematically shown below, and the scope necessary for explaining the relevant parts of the present disclosure will be mainly explained, and the parts for which explanation is omitted will be referred to as publicly known technologies. Furthermore, identical or similar reference numerals will be used for identical or corresponding components in the drawings, and duplicate explanations will be omitted. Furthermore, when a plurality of identical or corresponding components are included in the drawings, only some of them may be referenced to make the drawings easier to understand.

[0024] 1 is a schematic block diagram showing an example of a display control device according to an embodiment of the present disclosure. A display control device 10 according to this embodiment is mounted on and used in a vehicle 1. In addition, this display control device 10 can be configured as part of a driving assistance ECU (Electronic Control Unit) that constitutes a driving assistance system represented by an ADAS.

[0025] The display control device 10 can be configured as a computer including a microcontroller, etc. The computer may include a processor 11, a ROM (Read Only Memory) 12 and a RAM (Random Access Memory) 13 as examples of memory, a storage 14, a communication interface 15, and an input / output interface 16. These components may be connected to each other via an internal bus so that they can communicate with each other.

[0026] The processor 11 may be configured, for example, as a CPU (Central Processing Unit) and may be capable of executing various programs and controlling each part. Specifically, the processor 11 may be capable of reading various programs stored in the ROM 12 or the storage 14 and executing the programs using the RAM 13 as a work area. The processor 11 may be capable of controlling each component constituting the display control device 10 and performing various arithmetic processing according to the programs.

[0027] The ROM 12 may be capable of storing various programs and various data, and the RAM 13 may be capable of temporarily storing programs or data as a working area.

[0028] The storage 14 may be configured with a recording medium such as a hard disk drive (HDD), a solid state drive (SSD), or a flash memory, and may store various programs including an operating system and various data necessary to operate the display control device 10. In this embodiment, the ROM 12 or the storage 14 may store programs and various data for displaying desired information on the display 30. In addition, the storage 14 may also store map data used by the ACC.

[0029] The storage 14 according to the present embodiment may also store data related to a driving mode image 71 to be displayed on the display 30, which is an example of a display device, in accordance with the driving assistance mode. The driving assistance modes may include at least a deceleration assistance mode that provides only deceleration assistance and an adaptive cruise control (ACC) mode that includes acceleration / deceleration assistance for following a preceding vehicle at a fixed interval. In this embodiment, in addition to the two modes described above, a congestion following mode that is selected when a traffic jam occurs and includes acceleration / deceleration assistance for following a preceding vehicle at a fixed interval (e.g., hands-off driving) is illustrated. The storage 14 may also store data related to a deceleration assistance image 61 to be displayed on the display 30 when deceleration assistance is performed. The deceleration assistance image according to the present embodiment may be configured, for example, with an icon (or mark) representing an event requiring deceleration assistance. Specific examples of the driving mode image 71 and the deceleration assistance image 61 will be described later.

[0030] The communication interface (I / F) 15 may be an interface capable of wireless communication, which enables the display control device 10 to communicate with a server computer (not shown), various databases, a terminal device of a user (e.g., a passenger of the vehicle 1), etc. via a network, etc. This communication interface 15 may use communication standards such as CAN (Controller Area Network), Ethernet (registered trademark), LTE (Long Term Evolution), FDDI (Fiber Distributed Data Interface), or Wi-Fi (registered trademark).

[0031] The input / output interface (I / F) 16 may be an interface for transmitting and receiving data, etc., between various components necessary for display control, mainly mounted on the vehicle 1. The components electrically connected to the input / output interface 16 may be selected as appropriate. As shown in FIG. 1 , the input / output interface 16 of this embodiment can acquire desired data from, for example, a radar 21, a camera 22, sensors 23, and an input unit 24. The input / output interface 16 of this embodiment can also output specific data to a display 30 and an actuator 40. The components from which the input / output interface 16 acquires data can be various components related to driving assistance and are not limited to those described above. The components from which the input / output interface 16 outputs data are also not limited to those described above.

[0032] The radar 21 may be a radar for identifying three-dimensional objects present around the vehicle 1. Specifically, the radar 21 includes, for example, a transmitter and a receiver, and emits millimeter-wave band radio waves (hereinafter simply referred to as "millimeter waves") from the transmitter to the periphery of the vehicle 1, and receives the reflected waves with the receiver. Then, based on the time when the reflected waves were received, the degree of attenuation, etc., the radar 21 identifies three-dimensional objects within the range where the millimeter waves were emitted. The identification results by the radar 21 are transmitted to the display control device 10.

[0033] The camera 22 may be an imaging device capable of capturing images mainly in front of the vehicle 1. The camera 22 may be configured as a two-dimensional camera including a well-known image sensor such as a CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor) image sensor. The image captured by the camera 22 is transmitted to the display control device 10.

[0034] The sensors 23 may include various sensors mounted on the vehicle 1. Specifically, the sensors may include a vehicle speed sensor, an acceleration sensor, an accelerator pedal sensor, a brake pedal sensor, a steering angle sensor, a shift lever sensor, an ultrasonic sensor, etc. The sensors 23 may also include a positioning device such as a GPS (Global Positioning System). The results detected by the sensors 23 are transmitted to the display control device 10.

[0035] The input unit 24 is capable of receiving input operations from the user. The input unit 24 may include various switches, touch panels, levers, etc. installed in the vehicle cabin. In addition, the input unit 24 of this embodiment includes a switch that can switch the driving assistance mode. The content input via the input unit 24 is transmitted to the display control device 10.

[0036] The display 30 is a device for displaying information transmitted from the display control device 10. The display 30 can be configured with a well-known display such as a liquid crystal display (LCD) or an organic electro-luminescent display (OLED). The display 30 may also include a display driver (not shown). The display 30 only needs to be disposed in a position visible from the driver's seat in the vehicle interior, and can be disposed in any position such as in front of the driver's seat or in the center of the front of the vehicle interior.

[0037] The actuator 40 is a device that operates to control the vehicle 1, for example, to assist driving. The actuator 40 may include at least an actuator for a drive system such as an engine, and an actuator for a brake system such as a braking device. Note that the types of actuators are not limited to those described above, and may include various types such as an actuator for a steering system.

[0038] Fig. 2 is a functional block diagram showing an example of the software configuration of the display control device shown in Fig. 1. As shown in Fig. 2, the display control device 10 of this embodiment includes a data acquisition unit 51 that acquires mode information including a driving assistance mode of the vehicle 1 and information related to deceleration assistance for decelerating the vehicle 1, and a display control unit 52 that displays a driving mode image 71 corresponding to the acquired mode information on the display 30, and also specifies the display format of a deceleration assistance image 61 to be displayed in relation to the deceleration assistance so as to correspond to the display format of the driving mode image 71, and displays the specified image on the display 30.

[0039] The data acquisition unit 51 can be mainly realized by the input / output interface 16, and includes at least a function for acquiring mode information and information related to deceleration assistance. As described above, the mode information includes information related to any one of the deceleration assistance mode, the ACC mode, and the congestion following mode. Note that the ACC mode in this embodiment can be a map-linked ACC mode that realizes driving assistance linked with map information based on the map data stored in the storage 14 and the positioning results of the positioning device. Furthermore, the information related to deceleration assistance includes, for example, information related to the circumstances requiring deceleration assistance that can be obtained while driving. The information related to deceleration assistance can be identified based on road signs captured by the camera 22, route information that can be identified by taking map information into consideration, and the like.

[0040] The display control unit 52 can be realized mainly by the processor 11, and includes a function of controlling the display content to be displayed on the display 30. The display control unit 52 may include an image specification unit 53 that specifies an image to be displayed on the display 30, and a display format specification unit 54 that specifies a display format for the image, in particular, the deceleration support image 61 (see FIG. 4, etc.).

[0041] The image specifying unit 53 includes a function to specify a driving mode image 71 (see FIG. 4 etc.) that matches the selected driving assistance mode to be displayed on the display 30, from the mode information acquired by the data acquiring unit 51. In addition, the image specifying unit 53 also includes a function to specify a deceleration assistance image 61 to be displayed on the display 30, from the information related to deceleration assistance acquired by the data acquiring unit 51.

[0042] FIG. 3 is a diagram showing an example of a deceleration support image. The deceleration support image 61 identified by the image identification unit 53 may include an icon image that illustrates an event requiring deceleration support that the vehicle 1 encounters while traveling. Specifically, the image may include images such as those shown in FIGS. 3A to 3H. That is, examples of the deceleration support image include a deceleration support image 61A indicating a curve (see FIG. 3A), a deceleration support image 61B indicating a traffic light lane (see FIG. 3B), a deceleration support image 61C indicating an approaching vehicle ahead (see FIG. 3C), a deceleration support image 61D indicating a stop sign (see FIG. 3D), a deceleration support image 61E indicating a toll booth (see FIG. 3E), a deceleration support image 61F indicating a roundabout (circular intersection) (see FIG. 3F), a deceleration support image 61G indicating a yield (see FIG. 3G), and a deceleration support image 61H indicating a T-junction (see FIG. 3H). In this way, it is preferable to use an icon image that illustrates the above-mentioned event requiring deceleration support (such as the above-mentioned curve or traffic light lane) as the deceleration support image 61, because this allows the user to infer the event at a glance. Note that the deceleration support image 61 is not limited to the above-mentioned image as long as it is an image related to an event requiring deceleration support. Furthermore, among the above-mentioned deceleration support images 61A to 61H, the deceleration support images 61D to 61H correspond to landmarks that can be recognized in advance in the map-linked ACC mode.

[0043] Incidentally, even if the event requiring deceleration assistance is the same, the control behavior (for example, the trigger for starting deceleration assistance) may differ strictly depending on the driving assistance mode of the vehicle 1. In such a case, if the same image is displayed as the deceleration assistance image 61 on the display 30 regardless of the driving assistance mode, a driver who sees the image cannot identify at a glance in which driving assistance mode the deceleration assistance is being performed. Therefore, even if the same deceleration assistance image 61 is displayed, the control behavior may differ, and some drivers may feel uncomfortable with the behavior of the vehicle 1. In consideration of the above points, the display control device 10 according to the present embodiment employs an image that is easy for the user to understand at a glance, while providing a deceleration assistance image 61 to which information regarding the driving assistance mode currently in operation is also added, thereby eliminating the discomfort that the driver may feel.

[0044] In consideration of the above, the display control unit 52 of the display control device 10 according to this embodiment includes the display format specification unit 54, as described above. This display format specification unit 54 functions to specify the display format of an image to be displayed on the display 30, in particular the deceleration support image 61. Here, the display format may include at least one of the color of the deceleration support image 61, the line thickness of the deceleration support image 61, and the size of the deceleration support image 61. In the following description, an example in which the display format specification unit 54 specifies the color of the deceleration support image 61 will be given.

[0045] The display image displayed on the display 30 by the display control unit 52 will be described below with reference to FIGS.

[0046] FIG. 4 is a diagram showing an example of a display image in the deceleration assist mode. In the deceleration assist mode, the display 30 of the vehicle 1 may display a driving mode image 71A, or the driving mode image 71A and a deceleration assist image 61. As shown in FIG. 4, the driving mode image 71A may be configured, for example, with a host vehicle image 72 corresponding to the vehicle 1, a driving lane image 73 corresponding to the driving lane in which the vehicle 1 is traveling, and a white line image 74 corresponding to white lines indicating center lines, side strips, etc. extending along the driving lane. The deceleration assist image 61 may be configured, for example, with an icon indicating that the driving lane on the route is curved. Note that in the display image shown in FIG. 4, the deceleration assist image 61 is arranged so as to be connected to the end of the driving lane image 73 in the driving mode image 71A, but the position of the deceleration assist image 61 may be changed as appropriate.

[0047] The driving mode image 71 is displayed with each portion colored in an arbitrary color. Specifically, as shown in FIG. 4 , the driving mode image 71A in the display image displayed during the deceleration support mode is displayed with the driving lane image 73 portion, or the driving lane image 73 portion and the white line image 74 portion, colored in an arbitrary color, for example, gray. In the display control device 10 according to this embodiment, the display format specification unit 54 specifies the color of the deceleration support image 61 displayed together with the driving mode image 71A to a color corresponding to the color of the driving mode image 71A, i.e., gray. Once the color to be colored is specified, the deceleration support image 61 is displayed on the display 30 together with the driving mode image 71A after coloring an arbitrary region in the deceleration support image 61, for example, the icon portion 62 and the frame portion 63 surrounding it, gray. In this embodiment, the icon portion 62 and the frame portion 63 surrounding it of the deceleration support image 61 are colored gray as an example, but the colored portions are not limited to this. For example, it is possible to color the area inside the frame portion 63 but excluding the icon portion 62, or to color only either the icon portion 62 or the frame portion 63. Furthermore, it is sufficient for the color of the deceleration support image 61 to correspond to the color of the driving mode image 71, and the color shade, etc. may be different.

[0048] A user, particularly a driver, who views the display image shown in Figure 4 can immediately understand from the deceleration support image 61 displayed in a display format corresponding to the driving mode image 71A that deceleration support due to a curve on the route is being performed in deceleration support mode.

[0049] FIG. 5 is a diagram showing an example of a display image in ACC mode. In ACC mode, the display 30 of the vehicle 1 may display a driving mode image 71B, or the driving mode image 71B and a deceleration support image 61. As shown in FIG. 5, the driving mode image 71B may be configured, for example, with a host vehicle image 72, a driving lane image 73, a white line image 74, and a leading vehicle image 75 indicating a leading vehicle that is traveling ahead of the vehicle 1 and is the target of following. Similarly to FIG. 4, the deceleration support image 61 may be configured, for example, with an icon indicating a curve. Note that FIG. 5 illustrates an example in which the deceleration support image 61 is arranged to the side of the driving mode image 71B. Furthermore, the host vehicle image 72 and the leading vehicle image 75 may be colored in any desired manner.

[0050] As shown in FIG. 5 , the driving mode image 71B in the display image displayed in the ACC mode is displayed with the driving lane image 73 portion, or the driving lane image 73 portion and the white line image 74 portion, colored in an arbitrary color, for example, green, different from that of the driving mode image 71A. Changing the color used in the display image for each mode is effective in quickly informing a user viewing the display image of the current mode. In the display control device 10 according to this embodiment, the display format specification unit 54 specifies the color of the deceleration support image 61 displayed together with the driving mode image 71B to a color corresponding to the color of the driving mode image 71B, i.e., green. Once the color to be used is specified, the deceleration support image 61 is displayed on the display 30 together with the driving mode image 71B with any region of the deceleration support image 61, for example, the icon portion 62 and the frame portion 63 surrounding it, colored green.

[0051] A user, particularly a driver, who sees the display image shown in Figure 5 can immediately understand from the deceleration support image 61 displayed in a display format corresponding to the driving mode image 71B that deceleration support due to a curve on the route is being performed in ACC mode.

[0052] FIG. 6 is a diagram showing an example of a display image in the congestion following mode. In the congestion following mode, the display 30 of the vehicle 1 may display a driving mode image 71C, or the driving mode image 71C and a deceleration support image 61. As shown in FIG. 6, the driving mode image 71C may be configured, for example, with a host vehicle image 72, a driving lane image 73, a white line image 74, and a leading vehicle image 75, as well as a predicted driving trajectory image 76 that connects the host vehicle image 72 and the leading vehicle image 75 and indicates the predicted driving trajectory of the host vehicle. Similarly to FIG. 5, the deceleration support image 61 may be configured with an icon indicating a curve, for example, and may be arranged to the side of the driving mode image 71B.

[0053] 6, in a driving mode image 71C in a display image displayed during the congestion following mode, a driving lane image 73 portion, or a driving lane image 73 portion and a white line image 74 portion, are displayed in an arbitrary color, for example, blue, different from those of the driving mode images 71A and 71B. In the display control device 10 according to this embodiment, the display format specification unit 54 specifies the color of the deceleration support image 61 displayed together with the driving mode image 71C to a color corresponding to the color of the driving mode image 71C, that is, blue. Once the color to be used is specified, the deceleration support image 61 is displayed together with the driving mode image 71C after an arbitrary region in the deceleration support image 61, for example, an icon portion 62 and a frame portion 63 surrounding it, is colored blue.

[0054] A user, particularly a driver, who sees the display image shown in Figure 6 can immediately understand from the deceleration support image 61 displayed in a display format corresponding to the driving mode image 71C that deceleration support due to a curve on the route is being performed in congestion following mode.

[0055] As described above, according to the display control device 10 of this embodiment, a format corresponding to the display format of the selected driving assistance mode is adopted as the display format of the deceleration assistance image 61 displayed on the display 30. In other words, according to the display control device 10 of this embodiment, information about the driving assistance mode currently in operation is added to the deceleration assistance image by changing only the display format without changing the shape of the icon displayed as the deceleration assistance image, etc. This allows a user who views the image displayed on the display 30 to immediately and accurately grasp both the selected driving assistance mode and the details of the deceleration assistance.

[0056] Next, a display control method according to this embodiment will be described. The following describes, by way of example, a case in which the display control method according to this embodiment is implemented in a vehicle 1 including the above-described display control device 10. The display control method described below may be implemented by causing at least one processor 11 of a computer constituting the display control device 10 to execute a program that causes the computer to perform a predetermined operation. This program may be stored in a storage means such as the ROM 12 or the storage 14, or may be provided in the form of a non-transitory computer-readable recording medium.

[0057] The display control method according to this embodiment includes at least the steps of: displaying a driving mode image 71 corresponding to a driving assistance mode of the vehicle 1 on the display 30 provided in the vehicle 1 (corresponding to step S02 described later); adjusting the display format of the deceleration assistance image 61 to a display format corresponding to the display format of the driving mode image 71 when performing deceleration assistance (corresponding to step S05 described later); and displaying the adjusted deceleration assistance image 61 together with the driving mode image 71 (corresponding to step S06 described later). A specific example will be described below.

[0058] 7 is a flowchart showing an example of a display control method according to an embodiment of the present disclosure. The display control method according to this embodiment is started when the vehicle 1 is powered on and the user selects a driving assistance mode via the input unit 24. When a predetermined driving assistance mode is selected by the user, the display control device 10 acquires mode information using the data acquisition unit 51 (step S01). Next, the display control unit 52 identifies a driving mode image 71 that matches the acquired mode information so that the user can understand the driving assistance mode that is currently operating, and starts displaying the driving mode image 71 on the display 30 (step S02).

[0059] After the display of the driving mode image has started, if an event requiring deceleration support is detected, for example, a curve ahead is detected by the camera 22 of the vehicle 1 (Yes in step S03), the display process of the deceleration support image 61 is started. Specifically, first, the display control unit 52 identifies the deceleration support image 61 corresponding to the detected event requiring deceleration support (step S04). Next, the display control unit 52 adjusts the display format of the identified deceleration support image 61 to match the display format of the driving mode image 71 already displayed on the display 30 (step S05). In this embodiment, the display format is adjusted by adjusting the color of the deceleration support image 61 to be similar to the color of the driving mode image 71. Then, the display control unit 52 displays the deceleration support image 61 after the display format has been adjusted, together with the driving mode image 71, on the display 30 (step S06). Through the above process, the display control unit 52 completes the display of the deceleration support image 61. Note that the display of the displayed deceleration support image 61 is terminated when the event requiring deceleration support is resolved (for example, when the vehicle has completed negotiating the curve). Furthermore, when the driving assistance mode is changed, the display content of the driving mode image 71 is switched.

[0060] As described above, in the display control method and program according to this embodiment, the display format of the deceleration assistance image is adjusted to be the same as the display format of the driving mode image 71 being displayed on the display 30, so that the user can be immediately and accurately informed of both the event that caused the deceleration assistance and the operation assistance mode that is the premise for the deceleration assistance.

[0061] In addition, in each of the above embodiments, processor 11 refers to a processor in a broad sense, and includes general-purpose processors and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Specific Integrated Circuit, FPGA: Field Programmable Gate Array, programmable logic device, etc.).

[0062] Furthermore, the operations of the processor in each of the above embodiments may be performed not only by a single processor but also by multiple processors located at physically separate locations working together. Also, the order of the operations of the processor is not limited to the order described in each of the above embodiments and may be changed as appropriate.

[0063] The present disclosure is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present disclosure.
