Summary of the Invention

Problems to be Solved by the Invention

[0004] A vehicle may have a plurality of driving modes. It is required to make it easier for an operator to recognize the current driving mode.

[0005] Therefore, the purpose of this disclosure is to improve the recognizability of the current driving mode by the operator.

Means for Solving the Problems

[0006] A display system for a vehicle is a display system for a vehicle that can set a first driving mode and a second driving mode, and includes a display device that overlays and displays an information image indicating vehicle information on a background pattern, and a display control unit that sets a first background pattern as the background pattern when the first driving mode is set, and sets a second background pattern that is visually different from the first background pattern as the background pattern when the second driving mode is set, and controls the display of the display device.

[0007] Furthermore, the vehicle display method is a vehicle display method that allows setting a first driving mode and a second driving mode, wherein when the first driving mode is set, an information image showing vehicle information is superimposed on a first background pattern, and when the second driving mode is set, the information image is superimposed on a second background pattern that is visually different from the first background pattern. [Effects of the Invention]

[0008] This display system and method improves the operator's ability to recognize the current driving mode. [Brief explanation of the drawing]

[0009] [Figure 1] This is a schematic side view showing the overall configuration of a motorcycle according to the first embodiment. [Figure 2] This is a block diagram showing the electrical configuration of a motorcycle. [Figure 3] This figure shows an example of the display on the device during normal driving mode. [Figure 4] This figure shows an example of the display on the display device in walk mode. [Figure 5] This flowchart shows an example of the display process. [Figure 6] This flowchart shows an example of display processing according to the second embodiment. [Figure 7] This figure shows another example of the display on the device in normal driving mode. [Figure 8] This figure shows another example of the display on the display device in walk mode. [Modes for carrying out the invention]

[0010] {First Embodiment} <Overall Structure> The following describes a display system for vehicles, a vehicle, and a display method thereof according to the first embodiment. In this embodiment, an example in which the vehicle is a saddle-type vehicle is described. A saddle-type vehicle is a vehicle in which the driver straddles the seat when driving or when stopped. In this embodiment, an example in which the saddle-type vehicle is a motorcycle is described. Note that the motorcycle may be a scooter. It is not necessary for the saddle-type vehicle to be a motorcycle. The saddle-type vehicle may be an ATV (All Terrain Vehicle) such as a four-wheeled buggy vehicle, a personal watercraft, etc.

[0011] Figure 1 is a schematic side view showing the overall configuration of the motorcycle 10. In the following explanation, when referring to up and down, front and back, and left and right, each direction is defined as follows: The side of the motorcycle 10 where the front wheels 20 and rear wheels 22 are in contact with the road surface is down, and the opposite side is up. Also, the direction of travel when the motorcycle 10 is moving is forward, and the opposite side is backward. With the driver facing forward and riding the motorcycle 10, the left and right sides of the motorcycle 10 are relative to the driver.

[0012] The motorcycle 10 comprises a body frame 12, a front wheel 20, a rear wheel 22, and a power source 30. The front wheel 20 is rotatably supported on the front side of the body frame 12. The rear wheel 22 is rotatably supported on the rear side of the body frame 12. The power source 30 is mounted on the body frame 12. A handlebar device 40 is provided on the front side of the body frame 12. The direction of the front wheel 20 changes when the driver operates the handlebar device 40. The direction of travel of the motorcycle 10 changes as the direction of the front wheel 20 changes. A seat 28 on which the driver sits is provided on the upper side of the body frame 12, between the front wheel 20 and the rear wheel 22.

[0013] The power source 30 generates the power necessary for the motorcycle 10 to move. The power source 30 includes, for example, an electric motor for propulsion. In addition to, or instead of, the power source 30 may also include an internal combustion engine for propulsion. The following explanation mainly assumes that the power source 30 is an electric motor for propulsion. The power from the power source 30 is transmitted to the rear wheel 22 via a power transmission mechanism 32, thereby rotating the rear wheel 22. The power transmission mechanism 32 is, for example, a rotational transmission mechanism including a chain. The power transmission mechanism 32 may also include, for example, a gearbox that changes the rotational speed of the power source 30 by a combination of gears and transmits it to the rear wheel 22. The power source may be incorporated into the rear wheel or the front wheel. In this case, the power from the power source may be transmitted directly to the rear wheel or the front wheel.

[0014] The steering device 40 has a pair of left and right handle grips 42. The display device 50 is positioned around the steering device 40. For example, the display device 50 is positioned so that it can be seen by a driver seated on the seat 28 and holding the pair of handle grips 42. The display device 50 is positioned, for example, in front of the steering device 40. The display device 50 is supported by the steering device 40 and may rotate in conjunction with the steering of the steering device 40. The display device 50 may be supported in a fixed position on the vehicle frame 12 via a bracket or the like so that it does not rotate even when the steering device 40 is operated. The driver is both the operator of the motorcycle 10 and the operator of the display device 50.

[0015] The display device 50 is a device that displays an information image indicating vehicle information. The display device 50 is, for example, a liquid crystal display device or an organic EL (electro-luminescence) display device. The display device 50 is preferably capable of color display. As vehicle information, traveling information of the motorcycle 10 and state information of the motorcycle 10 itself are assumed. The information image is an image that shows information by symbols such as pictures, figures, or characters like pictograms. The information image includes information indicating the traveling state, information indicating the vehicle state, attached information, and the like. For example, the information image may include information indicating the traveling state that a driver needs to confirm during traveling, such as vehicle speed, outside air temperature, traveling distance, fuel consumption, and the like. Further, the information image may include information indicating the state of the vehicle, such as gear position, remaining fuel amount, engine temperature, traveling mode, abnormality display, and the like. Further, the information image may include attached information, information indicating new function information that does not affect traveling, for example, incoming call information of mail, phone, and the like. The incoming call information of mail and phone is incoming call information in a terminal device (such as a smartphone) possessed by a passenger, and is information acquired by a controller mounted on the vehicle communicating with the terminal device. A display example of the display device 50 will be described later.

[0016] The motorcycle 10 includes a walk mode switch 44. The walk mode switch 44 is a switch that switches the traveling mode of the motorcycle 10 between a normal traveling mode and a walk mode. The normal traveling mode is an example of the first traveling mode, and the walk mode is an example of the second traveling mode. The first traveling mode may be a mode with more traveling opportunities than the second traveling mode (that is, a mode with a high usage frequency, or a mode with a long usage time when assuming an average usage state). The first traveling mode may be a mode with fewer traveling restrictions than the second traveling mode. The second traveling mode may be a mode that requires a special operation by the driver to operate in the mode compared to the first traveling mode. The second traveling mode may be a mode with stricter conditions for execution than the first traveling mode.

[0017] The walk mode is a mode for controlling a traveling electric motor, which is an example of the traveling power source 30, in a state where at least a speed limit for throttle operation is imposed as compared with the normal traveling mode. The speed limit is, for example, a limit such that the speed is about the same as the walking speed, for example, a speed limit of 10 km / h or less at the maximum speed, or 6 km / h or less. The normal traveling mode is a normal driving mode in which the motorcycle 10 can travel on the road, and is a mode in which it can travel at a speed exceeding the maximum speed in the walk mode.

[0018] One of the pair of left and right handle grips 42 of the handle device 40 is a throttle. In the normal traveling mode and the walk mode, the rotational speed of the traveling power source 30 is controlled according to the throttle operation. In the walk mode, the motorcycle 10 is controlled to travel at a low speed under the above maximum speed limit. In the walk mode, compared with traveling in the normal traveling mode which is the first traveling mode, the change in driving force according to the increase or decrease in the grip operation amount or the amount of change per unit time may be slow.

[0019] The motorcycle 10 includes a start switch 46. The start switch 46 is a switch for switching the motorcycle 10 between a travelable state and a stopped state. By turning on the start switch 46, it can be switched to a travelable state in which the traveling power source 30 can be driven. By turning off the start switch 46, the power supply to the traveling power source 30 is cut off and it can be switched to a stopped state.

[0020] The walk mode switch 44 and the start switch 46 may be any man-machine interface that receives the operation of the driver, and may be, for example, a push switch, a slide switch, or a touch panel. The arrangement positions of the walk mode switch 44 and the start switch 46 are not particularly limited. The walk mode switch 44 and the start switch 46 may be provided on the handle device 40 or may be provided on the display device 50.

[0021] The motorcycle 10 may be equipped with brakes. For example, a brake lever may be mounted on at least one of the pair of handle grips 42. The rotational speed of the driving power source 30 may be controlled in response to the operation of the throttle and brake levers.

[0022] The power transmission mechanism 32 may include a gear shift mechanism with multiple gears. In this case, the speed control of the motorcycle 10 may be performed by controlling the driving power source 30 and the gear shift mechanism of the power transmission mechanism 32.

[0023] In walk mode, the motorcycle 10 may be capable of moving in reverse. For example, the motorcycle 10 may move forward by rotating the throttle from the neutral position in the forward direction, and the motorcycle 10 may move in reverse by rotating the throttle from the neutral position in the reverse direction. Switching between forward and reverse may be done by switching the control of the drive electric motor to switch the rotation direction of the driving power source 30 between the forward and reverse directions. Another example of forward / reverse switching is that the power transmission mechanism 32 has a gear for switching between forward and reverse, and by switching the gear, the rotation of the driving power source 30 in one direction may be switched and transmitted between rotation for forward and rotation for reverse.

[0024] The motorcycle 10 may be equipped with a battery 48. Power from the battery 48 is supplied to the drive power source 30 via a drive circuit 34. The drive circuit 34 is, for example, an inverter circuit.

[0025] The motorcycle 10 is equipped with a control device 61. The control device 61 is an electrical control device that controls various parts of the motorcycle 10. The control device 61 has a driving control processing function that includes a processing function for controlling the driving power source 30 via the driving drive circuit 34. In this embodiment, the motorcycle 10 can be set to a normal driving mode and a walk mode via a walk mode switch 44. When the normal driving mode is set, the control device 61 executes driving control processing that removes the restrictions imposed by the walk mode, and when the walk mode is set, it executes driving control processing with predetermined restrictions. The control device 61 has a processing function as a display control unit that controls the display of the display device 50.

[0026] <Block diagram> Figure 2 is a block diagram showing the electrical configuration of the motorcycle 10. The motorcycle 10 includes a display system 60 comprising a control device 61 and a display device 50.

[0027] The control device 61 is a microcomputer equipped with a processor 62, a storage device 64, etc. The control device 61 is an example of a processing circuit. The processor 62 is an electrical circuit including an arithmetic circuit, for example, a CPU (Central Processing Unit). The processor 62 may include one or more processor cores. Processing in the control device 61 may be realized by one or more processors 62 in the control device 61, or by the coordinated processing of multiple control devices. The storage device 64 is a non-volatile memory such as flash memory. The storage device 64 stores a software program 64a. The processor 62 executes arithmetic operations according to the processing procedures described in the program 64a, thereby executing processing to control the display of the display device 50, as will be described later. The storage device 64 also stores first background data 64b and second background data 64c. The first background data 64b and second background data 64c are data representing background patterns to be displayed as backgrounds placed around symbols shown as information images in the display device 50. The background pattern corresponds to the background image, or in other words, the margin, for the information image represented by the symbols. It is preferable that the background pattern create contrast with the information image to improve its visibility. For example, in the first driving mode, if the information image is black, the background pattern may be white. Alternatively, for example, in the first driving mode, if the information image is white, the background pattern may be black.

[0028] The control device 61 is connected to the display device 50, the drive circuit 34, the start switch 46, and the walk mode switch 44.

[0029] The display device 50 displays information according to the display control by the control device 61. The drive circuit 34 supplies power to the drive power source 30 in accordance with the control by the control device 61. The drive circuit 34 supplies power to control the rotational speed and rotational direction of the drive power source 30 in accordance with the command from the control device 61.

[0030] When the driver operates the start switch 46 or the walk mode switch 44, the operation is received by the start switch 46 or the walk mode switch 44. The received command is input from the start switch 46 or the walk mode switch 44 to the control device 61.

[0031] The control device 61 is connected to various other operation receiving devices 68 and various sensors 69.

[0032] The various operation receiving devices 68 are man-machine interfaces that receive operations from the driver, and are, for example, push switches, slide switches, or touch panels. The placement of the various operation receiving devices 68 is not particularly limited. Various commands to the motorcycle 10 are received through the various operation receiving devices 68 and input to the control device 61.

[0033] The various sensors 69 include, for example, a speed sensor, a sensor for measuring the remaining charge of the battery 48, a temperature sensor for the battery 48, or an illuminance sensor for detecting the brightness around the motorcycle 10. The detection results from the various sensors 69 are input to the control device 61.

[0034] The control device 61 can perform driving control of the motorcycle 10 and display control of the display device 50, etc., based on inputs from various operation receiving devices 68 and various sensors 69.

[0035] The control device 61 may be connected to a mobile terminal device such as a smartphone via a communication circuit to enable communication.

[0036] <Example of display on a display device> Figure 3 shows an example of the display on the display device 50 in normal driving mode. Figure 4 shows an example of the display on the display device 50 in walk mode.

[0037] The display device 50 has a display screen 52. On the display screen 52, an information image showing vehicle information is superimposed on a background pattern. In other words, the background pattern is displayed around the information image as a background or margin. The background pattern may have pattern information that includes the placement area of ​​the information image, and the placement area may be overwritten by the information image when it is superimposed on the background pattern. Alternatively, the background pattern may not have pattern information that includes the placement area of ​​the information image, and the background pattern may be displayed so as to spread around the information image.

[0038] Two background patterns are provided: a first background pattern 53a for normal driving mode and a second background pattern 53b for normal driving mode. The first background pattern 53a is defined by the first background data 64b, and the second background pattern 53b is defined by the second background data 64c. In the first driving mode, which is normal driving mode, the information image is superimposed on the first background pattern 53a. In the second driving mode, which is walk mode, the information image is superimposed on the second background pattern 53b, which is visually different from the first background pattern 53a.

[0039] Let us now explain in more detail an example of the display of the display device 50 in normal driving mode. In normal driving mode, the normal driving information image 54 and the common information image 55 are superimposed on the first background pattern 53a as information images for the first driving mode.

[0040] The normal driving information image 54 is an information image that is displayed in normal driving mode but not in walk mode. In other words, the normal driving information image is an information image exclusive to the first driving mode and is not displayed in the second driving mode. The normal driving information image 54 is an image that shows information related to driving in normal driving mode. In the first driving mode, several modes are further selectable. Specifically, the first mode is a mode with different output characteristics, and includes an eco mode that reduces fuel consumption, a sport mode that has improved output characteristics compared to eco mode, and a boost mode that temporarily increases acceleration performance. In this embodiment, the normal driving information image 54 includes an eco / sport mode information image 54a and a boost mode information image 54b. The eco / sport mode information image 54a is an information image that indicates whether it is a power-saving driving mode that limits the output of the driving power source 30 to suit power saving, or a sport mode in which the output limit for power saving is removed. Specifically, the eco / sport mode information image is displayed in the upper outer region, more specifically in the upper region. Boost mode is a mode that temporarily increases the output limit of the driving power source compared to the output limit during normal operation. Boost mode information image 54b is an image that shows the operating status of the boost mode.

[0041] The common information image 55 is an information image displayed in both normal driving mode and walking mode. The common information image is an image that shows information related to both normal driving mode and walking mode, or information that should be provided regardless of the mode. In this embodiment, the common information image 55 includes a speed information image 55a, a direction of travel information image 55b, a battery level image 55c, a battery temperature image 55d, an auxiliary driving information image 55e, a time image 55f, a setting image 55g, and a connection information image 55h. The common information image is preferably positioned near the center of the screen, specifically near the center in the vertical direction. In this embodiment, the common information images positioned near the center of the screen are the speed display image and the battery level display.

[0042] Speed ​​information image 55a is an image showing the speed of the motorcycle 10. Direction of travel information image 55b is an image showing the direction of travel of the motorcycle 10. For example, direction of travel information image 55b may display the forward state (D) in normal driving mode and the state in which forward and reverse movement is possible (F / R) in walk mode. If the vehicle is an HEV (Hybrid Electric Vehicle), direction of travel information image 55b may display the gear position (number from 1 to the last gear) in normal driving mode. Direction of travel information image 55b may display forward movement when moving forward (F) and reverse movement when moving backward (R). Battery level image 55c is an image showing the remaining charge of the battery 48. Multiple battery level images 55c can show the remaining charge of each battery 48 when multiple batteries 48 are provided. Battery temperature image 55d is an image showing the temperature of the battery 48. The auxiliary driving information image 55e is not mandatory to check while driving, but it contains information that may be useful as a reference, such as average fuel consumption and cumulative mileage. The time image 55f is an image that shows the current time. The setting image 55g is an image that shows that various settings are being made using switches or other devices separately provided on the vehicle. The connection information image 55h is an image that shows connection information between the motorcycle 10 and a mobile terminal device such as a smartphone.

[0043] The speed information image 55a is prominently located in the right-leaning area of ​​the vertical intermediate region. The direction of travel information image 55b is located to the left of the speed information image 55a. The two battery level images 55c are located to the left and right of the speed information image 55a and the direction of travel information image 55b.

[0044] The boost mode information image 54b is positioned between the vertical middle region and the upper edge region of the display screen 52, extending horizontally. The left edge of the boost mode information image 54b surrounds the top and right of the progress information image 55b. The boost mode information image 54b extends upward from its left edge to the right, and above the speed information image 55a, it extends horizontally.

[0045] The Eco / Sport mode information image 54a is located above the Boost mode information image 54b. The battery temperature image 55d is located to the left of both the Eco / Sport mode information image 54a and the Boost mode information image 54b.

[0046] The auxiliary driving information image 55e is located below the speed information image 55a, and the time image 55f, setting image 55g, and connection information image 55h are located below the battery level image 55c and direction of travel information image 55b on the left.

[0047] Let's explain in more detail an example of the display on the display device 50 in walk mode. The information image in normal driving mode and the information image in walk mode may be the same or different. In this embodiment, they are different.

[0048] In other words, in walk mode, the walk mode information image 56 and the common information image 55 are superimposed on the second background pattern 53b as information images for the second driving mode. The walk mode information image 56 is an information image that is displayed in walk mode but not in normal driving mode. In other words, the walk mode information image is an information image exclusive to the second driving mode that is not displayed in the first driving mode.

[0049] The walk mode information image 56 is an example of a second driving mode display image indicating that the vehicle is in walk mode. In this embodiment, the walk mode information image is an image showing the text "WALK MODE". The walk mode information image 56 does not have to be text; for example, it may be a diagram indicating that the vehicle is in walk mode. In walk mode, the normal driving information image 54 is not displayed, and instead, the walk mode information image 56 is displayed. By displaying the walk mode information image 56 instead of the normal driving information image 54, the display images on the display screen 52 are simplified and the amount of information is reduced. As a result, the walk mode information image 56 stands out in walk mode. Also, the second background pattern 53b is displayed more prominently. The walk mode information image 56 is located above the speed information image 55a. Displaying the walk mode information image 56 is not mandatory. It is preferable that the walk mode information image be positioned closer to the center of the screen, specifically closer to the vertical center. In this embodiment, it is positioned slightly above the center of the screen.

[0050] Since Walk Mode is an example of a second driving mode, Walk Mode information image 56 is an example of a second driving mode information image that indicates that the vehicle is in the second driving mode.

[0051] The common information image 55 is an information image that is also displayed in normal driving mode. The direction of travel information image 55b is an image that indicates that the vehicle can selectively move forward or backward according to the throttle operation, and in this case, the letters "F / " or " / R" are displayed. In walk mode, the normal driving information image 54 may also be displayed. The letters "F / " or " / R" may also be displayed as a walk mode information image to indicate that the vehicle is not in drive mode.

[0052] In walk mode, the walk mode information image 56 is displayed, allowing the driver to recognize that they are in walk mode. To ensure that the driver is more reliably aware that they are in walk mode, the first background pattern 53a and the second background pattern 53b are visually different.

[0053] A background pattern is defined by one or more combinations of, for example, color, shape, or shading. The first background pattern and the second background pattern are information that is perceived as visually different. Shape may be perceived as a background pattern. The background pattern may be a geometric shape or image, or a repeating pattern of a geometric shape or image. The background pattern may be a solid color pattern spread uniformly. The first background pattern 53a and the second background pattern 53b are visually different if they are perceived as different backgrounds by the eye and are set to different display modes. The two background patterns may differ, for example, in color, shape, or shading. For example, the first background pattern 53a and the second background pattern 53b may differ in color to such an extent that they are perceived as visually different colors, or they may differ in the underlying map shape represented by a line diagram or a repeating pattern of color divisions, or they may differ in shading patterns within the same color system to such an extent that they are perceived as visually different. Furthermore, the first background pattern 53a and the second background pattern 53b may be perceived as different backgrounds due to differences in multiple aspects, such as color, shape, or shade. The visual difference in background patterns may be brought about by changes in one or more combinations of color, shape, or shade over time. For example, the first background pattern may be a pattern that always displays the same background pattern, while the second background pattern may be a flashing pattern that repeatedly displays and stops the background pattern. The examples above are not limited to the first background pattern and the second background pattern, and it is sufficient that they are perceived as visually different.

[0054] To improve the visibility of information images 54, 55, and 56, it is preferable to use a simple background pattern. Furthermore, it is preferable to make the first background pattern 53a and the second background pattern 53b visually distinct from each other, even if the backgrounds are simple. For example, the first background pattern 53a and the second background pattern 53b may have different hues, saturations, or brightness. In addition to having different hues, saturations, or brightness, they may also have different hues, saturations, or brightness. Hue refers to the color, such as red, green, blue, yellow, purple, etc. Saturation is the degree of vividness of a color, and the degree to which white, gray, and black are mixed in. Brightness is the degree of lightness of a color; the lower the brightness, the closer it is to black, and the higher the brightness, the closer it is to white.

[0055] In this embodiment, the first background pattern 53a in the normal driving mode is a single-color plain pattern, for example, a plain white pattern.

[0056] In walk mode, the second background pattern 53b differs from the first background pattern 53a in at least some of its brightness. In this embodiment, the second background pattern 53b is a gradient pattern that includes areas where the color gradually changes. The second background pattern 53b includes an upper and lower intermediate area 53b3 as an example of a central area, and an upper area 53b1 and a lower area 53b5 as examples of outer areas.

[0057] The central region is the region located in the center of the entire first background pattern 53a, either vertically or horizontally. In this embodiment, it is the vertical intermediate region 53b3, located in the vertical center. The outer regions are the regions located outside the central region to the top, bottom, left, or right. In this embodiment, these are the upper region 53b1 and the lower region 53b5. The brightness of the vertical intermediate region 53b3 is different from the brightness of the upper region 53b1 or the lower region 53b5.

[0058] The brightness difference between the information images (e.g., information images 55a, 55b) in the vertical intermediate region 53b3 is greater than the brightness difference between the information images in the upper region 53b1 or lower region 53b5 (e.g., the image below information image 55e). For example, the vertical intermediate region 53b3 is bright, and the information images in this vertical intermediate region 53b3 (e.g., information images 55a, 55b) are dark, resulting in a large brightness difference between the two. The upper region 53b1 or lower region 53b5 is dark, and these regions are the same color as the information images in the vertical intermediate region 53b3, and are therefore dark. For this reason, the brightness difference in the vertical intermediate region 53b3 is greater than the brightness difference in the upper region 53b1 or lower region 53b5, making it easier to recognize the information images in the vertical intermediate region 53b3 (e.g., information images 55a, 55b).

[0059] More specifically, the brightness of the vertical intermediate region 53b3 of the second background pattern 53b is higher than the brightness of the upper region 53b1 and the lower region 53b5. The color gradually changes in the boundary region 53b2 between the vertical intermediate region 53b3 and the upper region 53b1, and in the boundary region 53b4 between the vertical intermediate region 53b3 and the lower region 53b5. The vertical intermediate region 53b3 may be the vertically central region of the display screen 52, or it may be a region that is biased upward or downward from the center.

[0060] Furthermore, the above brightness difference is maintained even when the brightness is reversed due to switching between day and night displays, etc. Also, the brightness of the central region in the left-right direction of the first background pattern may be higher than the brightness of the region to its right or left.

[0061] Considering that the normal driving mode is the state in which the motorcycle 10 performs its intended driving function, and that the walk mode is a special mode that is not constant compared to the normal driving mode, it is preferable that the second background pattern 53b is a more special background pattern than the first background pattern 53a.

[0062] In this respect, the gradient pattern described above is a special pattern as a background color compared to a background pattern with a uniform color throughout. Therefore, if the first background pattern 53a is a pattern that does not include areas where the color gradually changes, and the second background pattern 53b includes a gradient pattern, the driver will easily notice the change to the second background pattern 53b. As a result, the driver will easily recognize the second background pattern 53b and realize that they are in walk mode. In addition, since the gradient pattern itself is not a very complex pattern, it will not significantly affect the recognitionability of images 54, 55, and 56.

[0063] To give the second background pattern 53b a special feel compared to the first background pattern 53a, for example, the first background pattern 53a may be an achromatic pattern and the second background pattern 53b may be a chromatic pattern. Achromatic colors are colors with zero saturation, such as white, black, or gray between white and black. Chromatic colors are colors other than achromatic colors. For example, in the second background pattern 53b shown in Figure 4, the upper and lower regions 53b1 and 53b5 are chromatic regions, and the color may gradually change from the white region of the upper and lower intermediate region 53b3 towards the chromatic region. The chromatic color can be any color, for example, brown, blue, green, red, etc. If the second background pattern is chromatic, it may be set to a reddish color (red, vermilion, orange, yellow) to express its specialness. In this embodiment, both the upper and lower sides of the second background pattern are set to orange.

[0064] In this case, the chromatic areas of the second background pattern 53b differ in hue, saturation, and brightness from the plain white areas of the first background pattern 53a.

[0065] Given that the second background pattern 53b is the gradient pattern described above and is a chromatic pattern as described above, it is preferable that the saturation of the upper region 53b1 and the lower region 53b5 is higher than the saturation of the upper intermediate region 53b3. If the saturation is low, the background is less noticeable, making it easier to recognize the image displayed in the low-saturation region. If the upper intermediate region 53b3 has low saturation, it is easier to recognize the information displayed in the upper intermediate part of the display screen 52, such as the speed information image 55a and the direction of travel information image 55b.

[0066] It is not necessary for the saturation of both the upper region 53b1 and the lower region 53b5 to be higher than the saturation of the upper-lower intermediate region 53b3. The saturation of either the upper region 53b1 or the lower region 53b5 may be higher than the saturation of the upper-lower intermediate region 53b3.

[0067] From this perspective, even if the second background pattern 53b is not a gradient pattern, and even if the saturation of the upper and lower regions is higher than that of the upper and lower intermediate regions, the image displayed in the upper and lower central region can be made easier to recognize.

[0068] Furthermore, it is preferable that the second background pattern is formed as a gradient pattern, and that the display area of ​​the walk mode information image 56 and / or the display area of ​​the common information image 55 are set to be close to the pattern of the same area in the first background pattern. This makes it easier to bring the visibility of the walk mode information image 56 and / or the common information image 55 closer to the visibility in the first driving mode. Areas of the second background pattern that are not the display area of ​​the walk mode information image 56 and / or the display area of ​​the common information image 55 may be set to be far removed from the pattern of the same area in the first background pattern. By making the background pattern of these areas significantly different from the background pattern of the first background pattern, it is possible to improve the visibility of the walk mode information image 56 and / or the common information image 55 while making it easier to notice the difference in the background pattern.

[0069] From a similar perspective, even if the saturation of the left and right regions is higher than that of the left-right intermediate region, the image displayed in the left-right central region can still be easily recognized.

[0070] As described above, when the second background pattern 53b, which is a chromatic pattern, is displayed, the speed information image 55a and the direction of travel information image 55b are mainly located in the upper and lower intermediate region 53b3, and the walk mode information image 56 is mainly located in the boundary region 53b2. For this reason, the surrounding regions of the speed information image 55a, the direction of travel information image 55b, and the walk mode information image 56 have lower saturation than the upper region 53b1 and the lower region 53b5, which exhibit the highest saturation. If the surrounding regions of the speed information image 55a, the direction of travel information image 55b, and the walk mode information image 56 have low saturation, the speed information image 55a, the direction of travel information image 55b, and the walk mode information image 56 are easier to recognize.

[0071] It is not essential that the saturation of all surrounding areas of the speed information image 55a, the direction of travel information image 55b, and the walk mode information image 56 be lower than the highest saturation among the second background pattern 53b. However, if the saturation of the surrounding area of ​​the speed information image 55a, the direction of travel information image 55b, or the walk mode information image 56 is lower than the highest saturation among the second background pattern 53b, the speed information image 55a, the direction of travel information image 55b, or the walk mode information image 56 surrounded by the area of ​​lower saturation will be easier to see.

[0072] In this embodiment, the normal driving mode is understood in comparison to the walk mode. Therefore, the normal driving mode includes the boost mode and the eco / sport mode. Of course, the first driving mode and the second driving mode are understood in relation to the eco mode or boost mode relative to the sport mode, and different background patterns may be displayed for each.

[0073] <Examples of display processing by control devices> Figure 5 is a flowchart showing an example of display processing by the control device 61. This processing is executed, for example, in parallel or as pseudo-parallel processing with respect to the processing that the control device 61 performs for the operation of the motorcycle 10.

[0074] As shown in step S1, the control device 61 determines whether the start switch 46 has been turned on. The process in step S1 is repeated until the driver turns on the start switch 46. Once it is determined that the start switch 46 has been turned on, the process proceeds to step S2.

[0075] In step S2, the first background pattern 53a is displayed on the display device 50.

[0076] In the next step S3, it is determined whether the walk mode switch 44 is off. If it is determined that the walk mode switch 44 is off, the process proceeds to step S4. If the process proceeds to step S4, the walk mode switch 44 is off, and therefore the control device 61 either transitions to the normal driving mode or maintains the normal driving mode. If the walk mode switch 44 is not off, that is, if the walk mode switch 44 is turned on by the driver, the process proceeds to step S6. If the process proceeds to step S6, the walk mode switch 44 is on, and therefore the control device 61 transitions to walk mode.

[0077] In step S4, vehicle information images 54 and 55 are superimposed on the first background pattern 53a and displayed. In step S4, it is assumed that the motorcycle 10 is driving normally, and that the speed and other information corresponding to that normal driving are displayed.

[0078] In the next step S5, it is determined whether the start switch 46 is turned off. If it is determined that the start switch 46 is turned off, the process ends. If it is determined that the start switch 46 is not turned off, the process returns to step S3 and repeats.

[0079] When proceeding from step S3 to step S6, in step S6, the second background pattern 53b is displayed on the display device 50.

[0080] In the next step S7, vehicle information images 55 and 56 are superimposed and displayed on the second background pattern 53b. For example, the walk mode information image 56 is displayed in the area where the normal driving information image 54 is scheduled to be displayed. In step S7, the motorcycle 10 is set to walk mode. Therefore, the motorcycle 10 travels at a low speed in response to the driver's throttle operation. For example, if the driver operates the throttle in the forward direction, the motorcycle 10 moves forward at a low speed. Also, for example, if the driver operates the throttle in the reverse direction, the motorcycle 10 moves backward at a low speed. Depending on whether it is moving forward or backward, the display of the direction of travel information image 55b switches to "F" or "R", and the low speed is displayed in the speed information image 55a.

[0081] In the next step S8, it is determined whether the walk mode switch 44 is off. If it is determined that the walk mode switch 44 is off, the process proceeds to step S9. If the walk mode switch 44 is not off, the process returns to step S7 and continues in walk mode.

[0082] Step S9 determines whether the start switch 46 is turned off. If it is determined that the start switch 46 is turned off, the process ends. If it is determined that the start switch 46 is not turned off, the process returns to step S2, returns to normal driving mode, and repeats the subsequent process.

[0083] According to the display system 60 for the motorcycle 10, the motorcycle 10, and its display method configured as described above, the display of the display device 50 is controlled so that when the normal driving mode is set, the first background pattern 53a is set as the background pattern, and when the second driving mode is set, the second background pattern 53b, which is visually different from the first background pattern 53a, is set as the background pattern. As a result, the driver of the motorcycle 10 can recognize whether it is in normal driving mode or walking mode by looking at the background patterns 53a and 53b that spread out as the background on the display device 50. This makes it easy for the driver to recognize the current driving mode.

[0084] In particular, when the motorcycle 10 is a vehicle powered by an electric motor, the sound of the power source 30 is more difficult to recognize compared to a vehicle powered by an internal combustion engine. Therefore, it may be difficult to recognize differences in driving modes using the sound of the power source 30 in response to throttle and other operations as a clue. In such cases, the driver can easily recognize the current driving mode by looking at the background pattern.

[0085] Furthermore, if the hue, saturation, or brightness of the first background pattern 53a and the second background pattern 53b are different, the first background pattern and the second background pattern can be distinguished by these differences in hue, saturation, or brightness. For example, compared to cases where the shapes or patterns constituting the background patterns are different, even monotonous and inconspicuous patterns can be easily distinguished.

[0086] Furthermore, if the first background pattern 53a is a grayscale pattern and the second background pattern 53b is a chromatic pattern, the chromatic second background pattern 53b is easier to recognize. Therefore, the driver can more easily recognize that they are in walk mode.

[0087] In this case, if the second background pattern 53b, which is a chromatic pattern, includes an intermediate region 53b3 in the vertical direction, and an upper region 53b1 or lower region 53b5 with higher saturation than the intermediate region 53b3 in the vertical direction, the speed information image 55a and the direction of travel information image 55b can be more easily recognized in the intermediate region 53b3 in the vertical direction. In addition, by increasing the saturation of the upper region 53b1 or lower region 53b5, the second background pattern 53b can be more easily recognized due to its vividness.

[0088] Furthermore, the information image in walk mode includes a speed information image 55a, a direction of travel information image 55b, or a walk mode information image 56, and the surrounding area of ​​the speed information image 55a, direction of travel information image 55b, or walk mode information image 56 in the chromatic pattern has a lower saturation than the highest saturation in the chromatic pattern. Therefore, compared to the case where the speed information image 55a, direction of travel information image 55b, or walk mode information image 56 is surrounded by a high-saturation area, the displayed content of the speed information image 55a, direction of travel information image 55b, or walk mode information image 56 is easier to recognize.

[0089] Furthermore, since the second background pattern 53b is a gradient pattern, the vertical intermediate region 53b3, which is part of the background pattern, makes it easier to recognize the speed information image 55a and the direction of travel information image 55b, while the region where the color gradually changes gives a sense of specialness, making it easier for the driver to recognize that it is in walk mode.

[0090] Furthermore, in walk mode, the walk mode information image 56 is displayed on the second background pattern 53b. As a result, the driver can view the walk mode information image 56 with a visually altered appearance provided by the second background pattern 53b, and recognize the meaning of the change to the second background pattern 53b, that is, the current driving mode.

[0091] Furthermore, if the first driving mode is the normal driving mode and the second driving mode is an abnormal mode, the driver can easily recognize that they have switched to an abnormal mode that is different from the normal mode. The abnormal mode may be a mode in which the usage time in a saddle-type vehicle is shorter compared to the normal driving mode.

[0092] In particular, if the second driving mode is Walk mode, the driver can easily recognize that the current driving mode has changed to Walk mode.

[0093] {Second Embodiment} A display system for a saddle-type vehicle, a saddle-type vehicle, and a display method thereof according to the second embodiment will be described. In this description of the second embodiment, the differences from the first embodiment will be explained in particular.

[0094] In the second embodiment, an example is shown in which the control device 61 changes the brightness of the first background pattern and the second background pattern respectively according to the brightness of the environment to which the display device 50 is exposed.

[0095] In other words, the motorcycle 10 includes an illuminance sensor as one of the various sensors 69 that detects the brightness around the display device 50. The detection result of the illuminance sensor is output to the control device 61. The control device 61 compares the detection result of the illuminance sensor with preset brightness conditions to determine whether the environment to which the display device 50 is exposed is a bright environment or a dark environment. A bright environment is, for example, the brightness of daytime, and a dark environment is the brightness of nighttime. Rainy weather, cloudy weather, or evening conditions may be either a bright environment or a dark environment.

[0096] Figure 6 is a flowchart showing an example of display processing by the control device 61. The differences from the flowchart shown in Figure 5 will be explained in detail.

[0097] After step S1, the process proceeds to step S21. In step S21, it is determined whether or not the brightness condition is met based on the detection result of the illuminance sensor. For example, the illuminance based on the detection result of the illuminance sensor is compared with a threshold that defines the brightness condition. If the illuminance is equal to or greater than the threshold, it is determined that the brightness condition is met. If the illuminance based on the detection result of the illuminance sensor is less than or equal to the threshold, it is determined that the brightness condition is not met. If the illuminance based on the detection result of the illuminance sensor is the same as the threshold, it may be determined that the brightness condition is met or not met.

[0098] If it is determined that the brightness conditions are met, the process proceeds to step S2a, where the first background pattern 53a for a bright environment is displayed. Then, the process proceeds to step S3. If it is determined that the brightness conditions are not met, the process proceeds to step S2b, where the first background pattern 153a for a dark environment is displayed. Then, the process proceeds to step S3.

[0099] Examples of the first background pattern 53a for bright environments and the first background pattern 153a for dark environments will be explained later.

[0100] In step S3, it is determined whether the walk mode switch 44 is off. If it is determined that the walk mode switch 44 is off, the process proceeds to step S4. If the walk mode switch 44 is not off, that is, if the walk mode switch 44 has been turned on by the driver, the process proceeds to step S22.

[0101] In step S22, similar to step S21, it is determined whether the brightness conditions are met based on the detection results of the illuminance sensor. If it is determined that the brightness conditions are met, the process proceeds to step S6a, where the second background pattern 53b for a bright environment is displayed. Then, the process proceeds to step S7. If it is determined that the brightness conditions are not met, the process proceeds to step S6b, where the second background pattern 153b for a dark environment is displayed. Then, the process proceeds to step S7.

[0102] Examples of the second background pattern 53b for bright environments and the second background pattern 153b for dark environments will be explained later.

[0103] If it is determined in steps S5 and S9 that the start switch 46 is not turned off, the process returns to step S21. Also, if it is determined in step S8 that the walk mode switch 44 is not turned off, the process returns to step S22. Other processes are the same as those shown in Figure 5.

[0104] The first background pattern 53a for bright environments and the first background pattern 153a for dark environments will be described below. It is assumed that the degree of pupil dilation of the driver's pupils will differ depending on the ambient brightness. It is assumed that the degree of pupil dilation in dark environments will be smaller than that in bright environments. Therefore, by making the brightness of the first background pattern 153a for dark environments lower than that of the first background pattern 53a for bright environments, the driver will be able to see the information displayed on the display device 50 more easily.

[0105] For example, the first background pattern 53a for a bright environment may be a background pattern with high brightness, such as a plain white background, as shown in Figure 3. In contrast, the first background pattern 153a for a dark environment may be a background pattern with lower brightness than the first background pattern 53a, such as a plain black background pattern, as shown in Figure 7. For example, the first background pattern 153a may be a pattern in which the brightness of the first background pattern 53a is reversed. In this case, the information image may be a white-on-white image.

[0106] Similarly, for example, the second background pattern 53b for a bright environment may be a background pattern with high brightness, such as a gradient pattern that changes from white to another color, as shown in Figure 4. In contrast, the second background pattern 153b for a dark environment may be a background pattern with low brightness, such as a gradient pattern that changes from black to another color, as shown in Figure 8. The other color may be achromatic or chromatic. For example, the second background pattern 153b may be a pattern in which the brightness of the second background pattern 53b is reversed. In this case, the information image may be a white-on-white image.

[0107] According to the second embodiment, the same effects and advantages as in the first embodiment can be obtained. In addition, by changing the brightness of the first background patterns 53a, 153a and the second background patterns 53b, 153b according to the ambient brightness, the information displayed on the display device 50 can be made easier to recognize.

[0108] In this example, the brightness levels are classified into two categories, and an example was described in which the first background patterns 53a and 153a and the second background patterns 53b and 153b are each changed to two levels of brightness. The brightness levels may be classified into more categories, and the first background patterns 53a and 153a and the second background patterns 53b and 153b may each be changed to more levels of brightness.

[0109] {Example} In the first and second embodiments, an example was described in which the first driving mode is a normal driving mode and the second driving mode is a walking mode.

[0110] It is not necessary for the first and second driving modes to be the examples shown above. The first and second driving modes only need to differ in terms of vehicle driving restrictions. For example, the degree of driving restrictions may differ, or the presence or absence of restrictions may differ.

[0111] One possible combination of modes with different degrees of driving restrictions is the normal driving mode and the limp mode. The limp mode is a mode that limits the maximum speed, etc., in order to allow the rider to reach their home or a repair shop where a malfunction in the motorcycle can be resolved. Another possible combination of modes with different degrees of driving restrictions is the normal driving mode and the boost mode. The boost mode is a mode that temporarily increases the upper limit of the output of the driving power source compared to the normal driving mode.

[0112] One possible combination of modes with and without driving restrictions is the normal driving mode when the smart key is not lost, and the smart key loss detection mode. In other words, in motorcycles equipped with a smart key system that uses wireless communication for authentication, the system may periodically communicate with the smart key during driving to determine whether the smart key is lost or not. If the smart key is determined to be not lost, the motorcycle can be turned on again after authentication using the smart key, even if the motorcycle is turned off. If the smart key is determined to be lost, the motorcycle will not be able to be driven if it is turned off and the authentication authority is interrupted, as authentication using the smart key will not be possible. Therefore, the smart key not lost mode is a state without driving restrictions, while the smart key loss detection mode can be said to be a state with driving restrictions in that once it is turned off, it will not be able to be driven again.

[0113] As a specific example of a second driving mode, as already explained, it may be a mode with different driving characteristics, such as an eco mode or a sport mode, where the degree of driving restrictions differs from that of the first driving mode. Alternatively, the second driving mode may not be a mode with different driving restrictions, for example, a mode that indicates a difference in the power source compared to the first driving mode (a mode where the power source is an engine, a mode where the power source is a hybrid of an engine and an electric motor, or a mode where the power source is an electric motor). Thus, the second driving mode may be a mode in which the vehicle behavior in response to driving operations differs from that of the first driving mode.

[0114] The display in the first driving mode and the display in the second driving mode differ only in their backgrounds, and it may be understood that the information to be displayed is the same in both modes. Furthermore, it is preferable that the display system be applied to a display device for displaying various vehicle information, such as a display device used as the instrument panel of a vehicle, rather than a rearview monitor for displaying the back of the vehicle.

[0115] As examples of information images exclusive to the first driving mode, a mode display that distinguishes output characteristics (eco / sport) and a vehicle status display that shows special driving conditions such as boost mode have been provided, but this embodiment is not limited to these. Either a special driving condition or a mode that distinguishes output characteristics may be displayed. In addition, information images such as gear display, fuel consumption, and mileage display may be set as information images exclusive to the first driving mode.

[0116] Furthermore, this embodiment may also include cases where the walk mode information image 56 is not displayed.

[0117] Furthermore, the first driving mode may be understood as a normal driving mode, and the second driving mode may be understood as an abnormal mode in which the driving control for at least one operation differs from that of the first driving mode. The at least one operation may be, for example, throttle operation or operation to the start switch. The driving control may be rotational speed or output control of the driving power source, driving speed control, or on / off control of the operation of the driving power source.

[0118] In the first embodiment, the maximum speed limit for throttle operation differs between the normal driving mode and the walk mode. Therefore, the walk mode is an example of an abnormal mode in which the driving control for at least one operation differs compared to the normal driving mode.

[0119] The limp mode and boost mode described above are examples of non-normal modes in which the driving control for at least one operation differs from that of the normal driving mode. The smart key loss detection mode is also an example of a non-normal mode, as it differs from the normal driving mode in that the driving control for the power-on operation after the power-off operation is either permitted or denied. Switching between the normal driving mode and the limp mode, or between the normal driving mode and the smart key loss detection mode, may be done not by a switch operation by the driver, but based on the output of a sensor that detects a malfunction or the communication status of the smart key through a communication circuit.

[0120] Furthermore, the first driving mode and the second driving mode are assumed to be modes set to differ in the degree or presence of driving restrictions. For this reason, the first background pattern 53a displayed in the first driving mode and the second background pattern 53b displayed in the second driving mode are assumed to be background patterns displayed while driving. Accordingly, for example, the state of setting up a motorcycle using the display device, the state of starting up a motorcycle, or the state of filling up are not states that are set as driving modes. Also, even if a different background pattern from the normal driving mode is displayed on the display device during setting up, starting up, or filling up, this does not mean that the first background pattern is set in the first driving mode setting state and the first background pattern is set in the second driving mode setting state. Similarly, even if a different background pattern is displayed on the display device between daytime and nighttime, regardless of the driving mode, this display control does not mean that the first background pattern is set in the first driving mode setting state and the first background pattern is set in the second driving mode setting state.

[0121] In each of the embodiments described above, the case where the first background pattern 53a and the second background pattern 53b cover the entire display screen 52 was explained. The area over which the first background pattern and the second background pattern, which are changed according to the mode, extend may be only a part of the display screen.

[0122] Furthermore, the configurations described in each of the above embodiments and modifications can be combined as appropriate, as long as they do not contradict each other.

[0123] Furthermore, the display system according to this embodiment can be similarly applied to vehicles other than saddle-type vehicles. The vehicle may be a bicycle or a vehicle with three or more wheels. The vehicle may not be a saddle-type vehicle where the rider straddles the seat, but rather a vehicle in which steps are formed in front of the seat where both feet are placed.

[0124] The display device may be achromatic, with multi-level brightness adjustment. Alternatively, if the brightness is adjustable in multiple levels, it may be fixed to a single saturation level and not change.

[0125] The display device may have two types of displays, one inverting black and white depending on the ambient light. The driver may choose which of the two inverted black and white displays to use according to their preference. Alternatively, this embodiment may also include a display with only one of the black and white options.

[0126] Information images may be set separately depending on whether the surrounding environment is bright or dark. Furthermore, the central area of ​​the background pattern may be set to white when the environment is bright, and to black when the environment is dark.

[0127] This specification and its drawings disclose the following embodiments.

[0128] The first embodiment is a display system for a vehicle capable of setting a first driving mode and a second driving mode, comprising: a display device that displays an information image showing vehicle information superimposed on a background pattern; and a display control unit that controls the display of the display device so as to set a first background pattern as the background pattern when the first driving mode is set, and set a second background pattern that is visually different from the first background pattern as the background pattern when the second driving mode is set.

[0129] According to the first embodiment, when a first driving mode is set, a first background pattern is set as the background pattern, and when a second driving mode is set, a second background pattern that is visually different from the first background pattern is set as the background pattern. As a result, the operator of the vehicle can recognize whether it is in the first or second driving mode by looking at the background pattern displayed on the display device. This makes it easy for the operator to recognize the current driving mode.

[0130] The second embodiment is a vehicle display system according to the first embodiment, wherein the first background pattern and the second background pattern differ in hue, saturation, or brightness.

[0131] Thus, the first background pattern and the second background pattern are distinguished by differences in hue, saturation, or brightness.

[0132] The third embodiment is a vehicle display system according to the first or second embodiment, wherein the first background pattern is a grayscale pattern and the second background pattern is a chromatic pattern.

[0133] In this case, the second background pattern, which is a chromatic pattern, is easier to recognize. Therefore, the operator can more easily recognize that it is in the second driving mode.

[0134] A fourth embodiment is a vehicle display system according to any one of the first to third embodiments, wherein the second background pattern includes a central region and an outer region located outside the central region and having a different brightness from the central region, the brightness difference with respect to the information image in the central region is the same as that of the outer region in This is greater than the brightness difference with respect to the aforementioned information image.

[0135] In this way, by increasing the brightness difference in the central region of the information image, it becomes easier to recognize the information image in that central region.

[0141] This allows the operator to recognize the meaning of the second background pattern by viewing the second driving mode display image.

[0142] The eighth aspect is a vehicle display system according to any one of the first to seventh aspects, wherein the display control unit changes the brightness of the first background pattern and the second background pattern in accordance with the brightness of the environment to which the display device is exposed.

[0143] By changing the brightness of the first and second background patterns in accordance with the ambient light, the information displayed on the display device can be easily recognized.

[0144] The ninth embodiment is a display system for a vehicle according to any one of the first to eighth embodiments, wherein the first driving mode is a normal driving mode, and the second driving mode may be an abnormal mode in which the driving control for at least one operation is different compared to the first driving mode.

[0145] In this case, when the vehicle switches from normal driving mode to abnormal mode, the operator can easily recognize that it has switched to abnormal mode.

[0146] The tenth embodiment is a vehicle display system according to any one of the first to ninth embodiments, wherein the second driving mode is a walk mode in which, compared to the first driving mode, at least a speed limit is imposed on throttle operation.

[0147] In this case, the operator can easily recognize that they are in walk mode.

[0148] The eleventh embodiment is a vehicle equipped with a vehicle display system according to any one of the first to tenth embodiments.

[0149] This allows the vehicle operator to easily recognize the current driving mode.

[0150] The twelfth aspect is a display method for a vehicle in which a first driving mode and a second driving mode can be set, wherein when the first driving mode is set, an information image showing vehicle information is superimposed on a first background pattern, and when the second driving mode is set, the information image is superimposed on a second background pattern that is visually perceived differently from the first background pattern.

[0151] According to the twelfth embodiment, the operator of the vehicle can recognize whether it is in the first or second driving mode by looking at the background pattern displayed on the display device. This allows the operator to easily recognize the current driving mode.

[0152] Furthermore, this disclosure discloses a program and recording medium for implementing a process in which a computer that controls a display device for a vehicle capable of setting a first driving mode and a second driving mode superimposes an information image showing vehicle information onto a first background pattern when the first driving mode is set, and superimposes the information image onto a second background pattern that is visually different from the first background pattern when the second driving mode is set.

[0153] The above description is illustrative in all respects, and the invention is not limited thereto. It is understood that countless variations not illustrated can be conceivable without falling outside the scope of this invention. [Explanation of symbols]
