Description

[Technical Field]

[0001] The present disclosure relates to an information processing device. [Background technology]

[0002] Patent Document 1 discloses a technique in which an image showing the state of the surroundings of a vehicle is displayed on a display unit. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7086798 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, when an image showing the state of the surroundings of the vehicle is displayed on a display unit as in the technology of Patent Document 1, it is assumed that a background image displayed around the vehicle image showing the vehicle on the display unit moves at a speed corresponding to the vehicle speed in order to give the occupants of the vehicle a sense of speed. However, if the speed of movement of the background image continues to increase in proportion to an increase in the vehicle speed, the occupants may find the content displayed on the display unit annoying.

[0005] Therefore, the present disclosure aims to provide an information processing device that can reduce the annoyance that vehicle occupants feel from the display content of the display unit, compared to when the movement speed of the background image displayed on the display unit continues to increase in proportion to the increase in vehicle speed. [Means for solving the problem]

[0006] The information processing device of claim 1 displays, on a display unit, an animation in which a background image around a vehicle image showing the vehicle as seen from a virtual viewpoint moves in a predetermined direction at a moving speed corresponding to the vehicle speed, based on detection information detectable by the vehicle, and includes a control unit that gradually decreases the rate of change in the moving speed, which increases as the vehicle speed increases, as the vehicle speed increases.

[0007] In the information processing device according to claim 1, the control unit, based on the detection information, causes the display unit to display an animation in which a background image surrounding the vehicle image as seen from a virtual viewpoint moves in a predetermined direction at a speed corresponding to the vehicle speed. The control unit then gradually decreases the rate of change in the speed of the movement, which increases with increasing vehicle speed. This makes it possible for the information processing device to reduce the annoyance felt by vehicle occupants regarding the content displayed on the display unit, compared to when the speed of the background image displayed on the display unit continues to increase in proportion to the increase in vehicle speed.

[0008] The information processing device according to claim 2 is the information processing device according to claim 1, wherein the control unit stops the change in the moving speed when the vehicle speed increases to a predetermined value or more.

[0009] In the information processing device according to claim 2, the control unit stops changing the speed of movement of the background image when the vehicle speed increases to or exceeds a predetermined value. This makes it possible to prevent the background image from moving too fast and causing discomfort to vehicle occupants.

[0010] The information processing device according to claim 3 is the information processing device according to claim 1 or 2, wherein the control unit reduces the clarity of the background image when the vehicle speed increases to or exceeds a predetermined value.

[0011] In the information processing device according to claim 3, the control unit reduces the clarity of the background image when the vehicle speed increases to or above a predetermined value. As a result, according to the information processing device, the background image becomes difficult for the vehicle occupants to see when the vehicle speed increases to or above the predetermined value, thereby reducing the eyestrain of the occupants.

[0012] The information processing device of claim 4 is any one of claims 1 to 3, wherein when the control unit displays a landscape image on the display unit, the display size of the landscape image changes depending on the positional relationship with the vehicle, the control unit changes the display size of the landscape image regardless of changes in the vehicle speed.

[0013] In the information processing device according to claim 4, the control unit changes the display size of the scenic image regardless of changes in vehicle speed when displaying the scenic image on the display unit. This reduces the annoyance felt by vehicle occupants regarding the scenic image compared to when the display size of the scenic image changes continuously in response to changes in vehicle speed.

[0014] The information processing device of claim 5 is any one of claims 1 to 4, wherein the control unit moves the background image in the opposite direction to the traveling direction of the vehicle when the vehicle accelerates, and moves the background image in the traveling direction of the vehicle when the vehicle decelerates.

[0015] In the information processing device according to claim 5, the control unit moves the background image in the opposite direction to the vehicle's traveling direction when the vehicle accelerates, and moves the background image in the vehicle's traveling direction when the vehicle decelerates. As a result, the information processing device can express that the vehicle is traveling by moving the background image, and can make the vehicle occupants feel a sense of acceleration or deceleration based on the direction of movement of the background image. [Effects of the Invention]

[0016] As described above, the information processing device according to the present disclosure can reduce the annoyance felt by vehicle occupants regarding the content displayed on the display unit, compared to when the speed of movement of the background image displayed on the display unit continues to increase in proportion to an increase in vehicle speed.

[Figure 3] 10 is a graph showing the relationship between vehicle speed and changes in the moving speed of a background image. [Figure 4] 10 is a first display example displayed on the monitor.

[0018] The vehicle 10 according to this embodiment will be described below. Fig. 1 is a block diagram showing the hardware configuration of a vehicle 10. As shown in Fig. 1, the vehicle 10 includes a meter ECU (Electronic Control Unit) 20. The vehicle 10 is an example of a "vehicle" in the present disclosure, and the meter ECU 20 is an example of an "information processing device" in the present disclosure.

[0019] The meter ECU 20 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, a storage 24, an in-vehicle communication I / F (Interface) 25, an input / output I / F 26, and a wireless communication I / F 27. The CPU 21, the ROM 22, the RAM 23, the storage 24, the in-vehicle communication I / F 25, the input / output I / F 26, and the wireless communication I / F 27 are connected to each other via an internal bus 28 so as to be able to communicate with each other.

[0020] The CPU 21 is a central processing unit that executes various programs and controls each part. That is, the CPU 21 reads programs from the ROM 22 or the storage 24 and executes the programs using the RAM 23 as a work area. The CPU 21 controls each of the above components and performs various arithmetic processing in accordance with the programs recorded in the ROM 22 or the storage 24.

[0021] The ROM 22 stores various programs and various data. The RAM 23 serves as a working area for temporarily storing programs or data.

[0022] The storage 24 is configured with a storage device such as an eMMC (embedded multi media card) or a UFS (universal flash storage), and stores various programs and various data. An information processing program 24A is stored in the storage 24. The information processing program 24A is a program for causing the CPU 21 to execute specific processing (see FIG. 2), which will be described later.

[0023] The in-vehicle communication I / F 25 is an interface for connecting to other ECUs 30. The interface uses a communication standard based on the CAN protocol. The in-vehicle communication I / F 25 is connected to an external bus 29. Although not shown, in addition to the ECU 30, multiple ECUs are provided for each function of the vehicle 10.

[0024] The input / output I / F 26 is an interface for communicating with an in-vehicle device 40 mounted on the vehicle 10 .

[0025] The on-vehicle devices 40 are various devices mounted on the vehicle 10. The vehicle 10 includes a sensor group 42 and a monitor 44 as examples of the on-vehicle devices 40.

[0026] The sensor group 42 includes sensors for detecting the state of the vehicle 10 and the situation around the vehicle 10, such as a 3D-LiDAR, a millimeter wave sensor, an infrared sensor, a blinker sensor, an accelerator position sensor, a vehicle speed sensor, a steering angle sensor, an angular velocity sensor, a GPS (Global Positioning System) sensor, an illuminance sensor, a gyro sensor, and an acceleration sensor, as well as a plurality of cameras for capturing images around the vehicle 10. The sensor group 42 outputs the detection results of each sensor and the captured images by each camera to the meter ECU 20, the ECU 30, etc.

[0027] The monitor 44 is provided on a meter panel located in front of the driver's seat of the vehicle 10, and is a meter display for displaying operation suggestions related to functions of the vehicle 10 and images explaining the functions, etc. The monitor 44 is an example of a "display unit" in the present disclosure.

[0028] The wireless communication I / F 27 is a wireless communication module for communicating with external devices, and uses communication standards such as 5G, LTE, Wi-Fi (registered trademark), and Bluetooth (registered trademark).

[0029] The CPU 21 of the meter ECU 20 has, as functional components, an acquisition unit 21A and a control unit 21B. Each functional component is realized by the CPU 21 reading and executing an information processing program 24A stored in the storage 24. The control unit 21B is an example of a "control unit" in the present disclosure.

[0030] The acquisition unit 21A acquires various types of information. For example, the acquisition unit 21A acquires, as the various types of information, detection information that can be detected by the vehicle 10. The detection information includes the detection results of each sensor constituting the sensor group 42, captured images by each camera, and the like.

[0031] The control unit 21B performs display control related to the display on the monitor 44. For example, as the display control, the control unit 21B causes the monitor 44 to display a vehicle image 10A (see FIG. 4, etc.) showing the vehicle 10 as seen from a virtual viewpoint, based on the detection information acquired by the acquisition unit 21A. The virtual viewpoint is set in a three-dimensional virtual space with the position of the vehicle image 10A as the origin, and is defined by viewpoint coordinates and a viewpoint angle (orientation) in the virtual space. As an example, the virtual viewpoint is a viewpoint seen from a specific viewpoint coordinate above the vehicle image 10A in the virtual space at a specific viewpoint angle.

[0032] Furthermore, as the display control, based on the detection information acquired by the acquisition unit 21A, the control unit 21B causes the monitor 44 to display an animation in which a background image 60 (see FIG. 4, etc.) around the vehicle image 10A moves at a speed corresponding to the speed of the vehicle 10. The speed at which the background image 60 moves increases as the vehicle speed increases.

[0033] 2 is a flowchart showing the flow of the identification process executed by the meter ECU 20. The CPU 21 reads the information processing program 24A from the storage 24, loads it into the RAM 23, and executes it, thereby performing the identification process. As an example, the identification process is automatically and repeatedly performed at regular intervals.

[0034] 2, the CPU 21 acquires detection information that can be detected by the vehicle 10. Then, the CPU 21 proceeds to step S11.

[0035] In step S11, the CPU 21 displays various images on the monitor 44 based on the detection information acquired in step S10. The various images include a vehicle image 10A, a road image 50 (see FIG. 4, etc.) showing the road on which the vehicle 10 is traveling, and a background image 60. Specific examples of the various images will be described later. Then, the CPU 21 proceeds to step S12.

[0036] In step S12, the CPU 21 updates the display content of the monitor 44 based on the detection information acquired in step S10. For example, if the speed of the vehicle 10 increases, the CPU 21 increases the moving speed of the background image 60 displayed on the monitor 44, or if the vehicle 10 approaches another vehicle, the CPU 21 reduces the inter-vehicle distance between the vehicle image 10A on the monitor 44 and the image showing the other vehicle. Then, the CPU 21 proceeds to step S13.

[0037] In step S13, the CPU 21 determines whether the vehicle speed of the vehicle 10 is equal to or greater than a predetermined value, for example, 90 km / h. If the CPU 21 determines that the vehicle speed is equal to or greater than 90 km / h (step S13: YES), the process proceeds to step S14. On the other hand, if the CPU 21 determines that the vehicle speed is not equal to or greater than 90 km / h (step S13: NO), the process proceeds to step S16. As an example, the CPU 21 determines whether the vehicle speed is equal to or greater than 90 km / h, which is the predetermined value, based on the detection result of the vehicle speed sensor included in the sensor group 42.

[0038] In step S14, the CPU 21 stops changing the movement speed of the background image 60. That is, when the vehicle speed is 90 km / h or higher, the CPU 21 keeps the movement speed of the background image 60 constant regardless of an increase in vehicle speed. Then, the CPU 21 proceeds to step S15.

[0039] In step S15, the CPU 21 reduces the clarity of the background image 60 compared to when the vehicle speed is less than 90 km / h. In other words, when the vehicle speed is 90 km / h or higher, the CPU 21 reduces the ease with which the driver, who is an occupant of the vehicle 10, can visually confirm the background image 60. Then, the CPU 21 proceeds to step S16.

[0040] In step S16, the CPU 21 determines whether a predetermined termination condition is met. If the CPU 21 determines that the termination condition is met (step S16: YES), the CPU 21 terminates the specific processing. On the other hand, if the CPU 21 determines that the termination condition is not met (step S16: NO), the CPU 21 returns to step S10. As an example, the CPU 21 determines that the termination condition is met when the ignition switch of the vehicle 10 is turned off.

[0041] Next, the relationship between the vehicle speed and changes in the moving speed of the background image 60 will be described with reference to Fig. 3. Fig. 3 is a graph showing the relationship between the vehicle speed and changes in the moving speed of the background image 60. In this graph, the vertical axis represents the moving speed of the background image 60, and the horizontal axis represents the vehicle speed.

[0042] During a period T1 in which the vehicle speed is equal to or greater than 0 km / h and less than 30 km / h, the moving speed increases at the gradient indicated by line segment L1 as the vehicle speed increases.

[0043] During the period T2 when the vehicle speed is equal to or greater than 30 km / h and less than 60 km / h, the vehicle speed increases at the slope indicated by line segment L2, which is gentler than the slope indicated by line segment L1.

[0044] During a period T3 in which the vehicle speed is equal to or greater than 60 km / h but less than 90 km / h, the vehicle speed increases at the slope indicated by line segment L3, which is gentler than the slope indicated by line segment L2.

[0045] As shown above, during periods T1, T2, and T3 when the vehicle speed is greater than or equal to 0 km / h and less than 90 km / h, the moving speed increases as the vehicle speed increases, but the rate of change in moving speed indicated by the slope of the graph gradually decreases as the vehicle speed increases.

[0046] During a period T4 in which the vehicle speed is equal to or greater than 90 km / h, an example of a predetermined value, the slope is 0, as indicated by line segment L4. Thus, when the vehicle speed increases to 90 km / h or greater, the change in the movement speed of background image 60 stops. Then, during period T4, background image 60 moves at an upper limit speed, which is the upper limit of the movement speed.

[0047] Next, examples of displays on the monitor 44 will be described with reference to FIGS. 4 shows a first example of a display displayed in the display area X of the monitor 44. The display area X is a partial area of ​​the monitor 44, and is visible to the driver seated in the driver's seat through an opening in the steering wheel. As an example, FIG. 4 shows the display content when the vehicle 10 is accelerating.

[0048] 4, a vehicle image 10A is displayed on a road image 50, facing upward in the drawing, indicating the traveling direction of the vehicle 10. The road image 50 is an image showing the roads around the vehicle 10 shown in map data stored in an external server or storage 24, etc.

[0049] The vehicle image 10A is an image generated based on an illustration design of the vehicle 10 shown in the illustration data stored in the storage 24. As an example, the vehicle 10 is traveling on a straight road. Therefore, in FIG. 4, the vehicle image 10A is displayed from a viewpoint seen from the virtual viewpoint within the straight road shown in the road image 50. The vehicle image 10A is an example of a "vehicle image" in the present disclosure.

[0050] Additionally, a background image 60 represented by six streamlines extending to the left and right of the road image 50 is displayed around the vehicle image 10A. Here, as the vehicle 10 accelerates, the six streamlines move in the opposite direction to the traveling direction of the vehicle 10, specifically, downward in the drawing as indicated by arrow d1. Then, after moving to a predetermined lower end position, the streamlines temporarily disappear from the monitor 44, and then reappear from a predetermined upper end position and move downward again in the drawing. In this way, when the vehicle 10 accelerates, an animation in which the background image 60 moves downward in the drawing is displayed on the monitor 44. The background image 60 is an example of a "background image" in the present disclosure, and the downward direction in the drawing as indicated by arrow d1 is an example of a "predetermined direction" in the present disclosure.

[0051] As described above, during periods T1, T2, and T3 (see FIG. 3) when the vehicle speed is equal to or greater than 0 km / h and less than 90 km / h, the background image 60 moves faster downward in the drawing as the vehicle speed increases.

[0052] 4, a landscape image 70 showing the scenery around the vehicle 10 is displayed above the road image 50. The landscape image 70 is an image showing the scenery around the vehicle 10 identified from the map data. The landscape image 70 is an example of a "landscape image" in the present disclosure.

[0053] As an example, the landscape image 70 is an illustration image that imitates Mount A, which is present around the vehicle 10, as a landscape of a predetermined mountain road. The illustration data of Mount A is stored, for example, in the storage 24. When the traveling location of the vehicle 10 has changed to a mountain road, the CPU 21 acquires the illustration data of Mount A from the storage 24 and draws it as the landscape image 70. It should be noted that which part of the road shown in the map data corresponds to the mountain road is determined in advance, and the CPU 21 determines whether the traveling location of the vehicle 10 has changed to a mountain road based on the detection information and the map data.

[0054] Here, the display size of the landscape image 70 changes depending on the positional relationship with the vehicle 10. As an example, in this embodiment, the display sizes of the landscape image 70 are provided as a small size, a medium size larger than the small size, and a large size larger than the medium size.

[0055] As an example, when the distance between the vehicle 10 and Mount A is equal to or greater than a first distance, the CPU 21 displays the landscape image 70 in a small size. Furthermore, when the distance between the vehicle 10 and Mount A is less than the first distance and equal to or greater than a second distance shorter than the first distance, the CPU 21 displays the landscape image 70 in a medium size. Furthermore, when the distance between the vehicle 10 and Mount A is less than the second distance, the CPU 21 displays the landscape image 70 in a large size. Thus, unlike the background image 60, whose moving speed changes in response to changes in vehicle speed, the display size of the landscape image 70 changes depending on the distance between the vehicle 10 and Mount A, regardless of changes in vehicle speed. As an example, the display size of the landscape image 70 shown in FIG. 4 is medium.

[0056] Fig. 5 is a second display example displayed in the display area X of the monitor 44. As an example, Fig. 5 shows the display content when the vehicle speed increases to 90 km / h or more. Fig. 5 shows the case when the vehicle 10 accelerates from the state shown in Fig. 4, and the six streamlines shown as the background image 60 move downward in the drawing as indicated by arrow d1 compared to Fig. 4.

[0057] As described above, when the vehicle speed increases to 90 km / h or more, the CPU 21 stops changing the movement speed of the background image 60. Therefore, in the state shown in Fig. 5, the background image 60 moves downward in the drawing, as indicated by the arrow d1, at a constant upper limit speed, regardless of the increase in vehicle speed.

[0058] Furthermore, as described above, when the vehicle speed increases to 90 km / h or higher, the CPU 21 reduces the clarity of the background image 60. In this embodiment, the clarity of the background image 60 is reduced by reducing the thickness of the six streamlines shown in the background image 60. Therefore, the background image 60 shown in FIG. 5 has thinner six streamlines than the background image 60 shown in FIG. 4.

[0059] Fig. 6 is a third display example displayed in the display area X of the monitor 44. As an example, Fig. 6 shows the display content when the vehicle 10 is decelerating. Fig. 6 shows a case where the vehicle 10 has decelerated from the state shown in Fig. 4, and the six streamlines shown as the background image 60 have moved upward in the drawing, as indicated by arrow d2, compared to Fig. 4.

[0060] 6 displays a vehicle image 10A, a road image 50, a background image 60, and a landscape image 70. The display manner of each of the above images is the same as in FIG. 4, so the description will be omitted or simplified.

[0061] 4 and 5, the background image 60 is shown by six streamlines extending to the left and right of the road image 50. Here, when the vehicle 10 decelerates, the six streamlines move in the traveling direction of the vehicle 10, specifically, upward in the drawing as indicated by arrow d2. Then, after moving to a predetermined upper end position, the streamlines temporarily disappear from the monitor 44, and then reappear from a predetermined lower end position and move upward again in the drawing. In this way, when the vehicle 10 decelerates, an animation of the background image 60 moving upward in the drawing is displayed on the monitor 44.

[0062] As described above, in the meter ECU 20, the CPU 21, as a function of the control unit 21B, based on the detection information, causes the monitor 44 to display an animation in which the background image 60 around the vehicle image 10A as seen from a virtual viewpoint moves downward in the drawings (opposite to the traveling direction of the vehicle 10) as indicated by the arrow d1 in FIGS. 4 and 6 at a moving speed corresponding to the vehicle speed of the vehicle 10. Then, the CPU 21, as a function of the control unit 21B, gradually decreases the rate of change in the moving speed, which increases with an increase in vehicle speed, as the vehicle speed increases. As a result, the meter ECU 20 can reduce the annoyance felt by the driver regarding the display content on the monitor 44, compared to when the moving speed of the background image 60 displayed on the monitor 44 continues to increase in proportion to an increase in vehicle speed.

[0063] Furthermore, in the meter ECU 20, the CPU 21, as a function of the control unit 21B, stops the change in the moving speed of the background image 60 when the vehicle speed increases to 90 km / h or more, which is an example of a predetermined value. As a result, the meter ECU 20 can prevent the moving speed of the background image 60 from becoming too fast and causing the driver to feel annoyed.

[0064] Furthermore, in the meter ECU 20, the CPU 21, as a function of the control unit 21B, reduces the clarity of the background image 60 when the vehicle speed increases to 90 km / h or higher. As a result, according to the meter ECU 20, the background image 60 becomes difficult for the driver to see when the vehicle speed increases to 90 km / h or higher, thereby reducing eye strain on the driver.

[0065] Furthermore, in the meter ECU 20, the CPU 21, as a function of the control unit 21B, changes the display size of the scenic image 70 regardless of changes in vehicle speed when displaying the scenic image 70 on the monitor 44. As a result, the meter ECU 20 can reduce the annoyance felt by the driver regarding the scenic image 70 compared to when the display size of the scenic image 70 continuously changes in response to changes in vehicle speed.

[0066] Furthermore, in the meter ECU 20, the CPU 21, as a function of the control unit 21B, moves the background image 60 in the opposite direction to the traveling direction of the vehicle 10 when the vehicle 10 accelerates, and moves the background image in the traveling direction of the vehicle 10 when the vehicle 10 decelerates. As a result, the meter ECU 20 can express that the vehicle 10 is traveling by moving the background image 60, and can make the driver feel a sense of acceleration or deceleration based on the direction of movement of the background image 60.

[0067] (others) Although the embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings, the technical scope of the present disclosure is not limited to such examples. It is clear that a person skilled in the art of the present disclosure can conceive of various modifications or alterations within the scope of the technical idea described in the claims, and it is understood that these modifications or alterations also naturally fall within the technical scope of the present disclosure.

[0068] Furthermore, the effects described in the above embodiments are explanatory or exemplary and are not limited to those described in the above embodiments. In other words, the technology according to the present disclosure may achieve other effects that are obvious to a person skilled in the art of the present disclosure from the description in the above embodiments, in addition to or instead of the effects described in the above embodiments.

[0069] The processes described in the above embodiments can also be realized by dedicated hardware circuits, in which case they may be executed by a single piece of hardware or by multiple pieces of hardware.

[0070] In the above embodiment, the information processing program 24A is stored in the storage 24. However, this is not limitative, and the information processing program 24A may be stored in the ROM 22.

[0071] In the above embodiment, the background image 60 is expressed by flow lines, but the display content of the background image 60 is not limited to this. For example, the background image 60 may be an image showing targets such as poles, roadside trees, and buildings that are identified based on the detection information.

[0072] In the above embodiment, the landscape image 70 is an image that imitates a mountain to show the scenery of a predetermined mountain path, but the display content of the landscape image 70 is not limited to this. For example, the landscape image 70 may be an image that imitates the sea to show the scenery of a predetermined seaside, or an image that imitates a building to show the scenery of a predetermined urban area, etc.

[0073] In the above embodiment, the clarity of the background image 60 is reduced by thinning the thickness of the six streamlines shown as the background image 60, but the method of reducing the clarity is not limited to this. For example, the clarity of the background image 60 may be reduced by reducing the number of streamlines from six to four, lightening the color of the streamlines, or the like.

[0074] In the above embodiment, the change in the movement speed of the background image 60 is stopped when the vehicle speed increases to or above a predetermined value. However, this is not limited to this. For example, depending on the state of the vehicle 10 and the location where the vehicle 10 is traveling, the change in the movement speed of the background image 60 may not be stopped and the movement speed of the background image 60 may be increased as the vehicle speed increases, even when the vehicle speed increases to or above a predetermined value. Specifically, when the vehicle 10 is in an autonomous driving mode in which the ECU 30 performs some or all of the driving operations of the vehicle 10, such as acceleration, braking, and steering, without the driver's intervention, the CPU 21 may increase the movement speed of the background image 60 as the vehicle speed increases, even after the vehicle speed increases to or above a predetermined value. Furthermore, when the vehicle 10 is traveling in a specific location where motorsports are held, such as a circuit or rally course, where sports driving is possible, where the vehicle 10's speed limiter is activated and the vehicle is driven at a higher speed, the CPU 21 may increase the movement speed of the background image 60 as the vehicle speed increases, even after the vehicle speed increases to or above a predetermined value.

[0075] In the above embodiment, the CPU 21 may change the display mode of the background image 60 depending on whether the vehicle 10 is accelerating or decelerating. In other words, the CPU 21 may change the display mode of the background image 60 depending on whether the background image 60 is moved opposite to the traveling direction of the vehicle 10 or towards the traveling direction of the vehicle 10. For example, the CPU 21 may change the color of the six streamlines shown as the background image 60 depending on whether the vehicle 10 is accelerating or decelerating.

[0076] In the above embodiment, the monitor 44, which is a meter display, is an example of a "display unit" of the present disclosure, but the "display unit" is not limited to a meter display. For example, the "display unit" may be another display such as a center display or a head-up display (HUD). Furthermore, the "display unit" may be a combination of multiple displays such as a meter display and a center display.

[0077] In the above embodiment, the meter ECU 20 executes the specific processing shown in Fig. 2. However, the present invention is not limited to this, and the specific processing may be executed by the meter ECU 20 in cooperation with another ECU.
