Display device

Abstract

A display device (1) according to the present disclosure is provided so as to be able to switch between a first display mode (4) and a second display mode (5) in which the display formats of content information and output information are different. A first frame line (51) having a shape that corresponds to a region where at least the output information is displayed, is displayed in the first display mode (4). When switching from the first display mode (4) to the second display mode (5), the display device (1) reproduces, in order, first transition moving images (61) and second transition moving images (62). In the first transition moving images (61), the brightness of the display content other than the first frame line (51) is reduced while the first frame line (51) is decreased in size toward the approximate center of the screen. In the second transition moving images (62), after the first frame line (51) has decreased in size toward the approximate center of the screen, a plurality of second frame lines (52) that are similar to the first frame line (51) are continuously displayed so as to gradually decrease in size toward the approximate center of the screen.

Description

[Technical Field]

[0001] The present invention relates to a display device that is mounted on a vehicle and displays vehicle speed information, output information, and the like. [Background technology]

[0002] Conventionally, among display devices that display vehicle speed information and output information (engine output-related information, motor output-related information, etc.) of a vehicle, there are known ones that display images that mimic existing analog meters. For example, there are known ones that display an image equivalent to the analog meter as viewed from the front, and ones that display an image equivalent to the analog meter as viewed obliquely from a viewpoint shifted from the front. It has also been proposed to make these display modes (image layouts) switchable (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-002808 Summary of the Invention [Problem to be solved by the invention]

[0004] In conventional display devices, the display position and size of information may change when the display mode is switched. This can easily confuse users about the change in display content before and after the switch, making it difficult to improve viewability. In particular, viewability is significantly reduced when the type or amount of information changes as a result of switching the display mode. Furthermore, if the image before the switch is simply erased and the image after the switch is suddenly displayed when switching the display mode, such a screen presentation may give the user a cheap impression and may degrade the user experience (emotions, impressions, and reactions that the user experiences through operation inputs to the display device and outputs from the display device, etc.).

[0005] One of the objectives of the present invention, which was conceived in light of the above-mentioned problems, is to provide a display device that improves the dramatic effect associated with switching display modes, thereby improving viewability and user experience. In addition to this objective, another objective of the present invention is to achieve effects derived from the configurations shown in the "Mode for Carrying Out the Invention" described below, which are not obtainable with conventional technology. [Means for solving the problem]

[0006] The disclosed display device can be realized as the following disclosed aspects or application examples, and solves at least part of the above-mentioned problems. The display device disclosed herein displays content information representing a vehicle's running state or an operating state of an in-vehicle device and output information representing an output of the vehicle, and is switchable between a first display mode and a second display mode in which the content information and the output information are displayed in different ways. In the first display mode, a first frame line having a shape corresponding to at least an area in which the output information is displayed is displayed.

[0007] Furthermore, when switching from the first display mode to the second display mode, a first transition video is played in sequence, in which the first frame line is reduced toward the center of the screen while the brightness of the display content other than the first frame line is reduced, and a second transition video is played in sequence, in which the first frame line is reduced toward the center of the screen, and then a plurality of second frame lines similar to the first frame line are displayed so as to be successively reduced toward the center of the screen. [Effects of the Invention]

[0008] According to the disclosed display device, when switching from the first display mode to the second display mode, the first transition video and the second transition video are played in sequence, thereby improving the presentation effect and improving viewability and user experience.

[0010] [1. Configuration] FIG. 1 is a block diagram showing the configuration of a display device 1 according to an embodiment. The display device 1 is a device mounted on a vehicle to display vehicle speed information and output information. The vehicle speed information is information that indicates the traveling speed of the vehicle. This vehicle speed information is generated by various ECUs, such as a vehicle ECU (Electronic Control Unit) and a powertrain ECU. It is also possible to generate the vehicle speed information within the display device 1 based on a vehicle speed signal transmitted from a vehicle speed sensor.

[0011] The output information is information relating to the output (power) of the vehicle's drive source. Specific examples of the output information include the engine rotation speed, engine torque, engine horsepower (power), traction motor rotation speed, traction motor torque, traction motor horsepower (power), power consumption of the traction motor, and power supply of the drive battery. The output information is generated, for example, by various ECUs and transmitted to the display device 1. Vehicle speed information can be considered to be included in the broad definition of output information.

[0012] The display device 1 can also display content information that indicates the vehicle's driving status and the operating status of in-vehicle devices. Specific examples of content information that indicates the vehicle's driving status include the shift position, the reduction ratio of the transmission, the name of the driving mode, the driving distance, the estimated remaining driving distance, the fuel economy, the electricity consumption, the remaining battery capacity, the yaw rate, the roll rate, the pitch rate, the longitudinal acceleration, the lateral acceleration, the road surface inclination angle, the tire pressure, the energy flow of the powertrain, the driving direction (orientation), the altitude, the temperature, and the road surface friction coefficient.

[0013] Furthermore, content information indicating the operating status of in-vehicle devices includes audio information, car navigation information, lighting status information, cruise control related information, vehicle distance information, various websites, etc. This information is generated or acquired by, for example, various ECUs, various in-vehicle devices, various sensors, etc., and transmitted to the display device 1.

[0014] As shown in FIG. 1, the display device 1 includes an electronic control device 2 and an output device 3. The electronic control device 2 is a computer for controlling the content displayed on the output device 3, and includes a processor (arithmetic processing unit) and a memory (storage device). The processing content (program) of the electronic control device 2 is stored in the memory, and is executed by loading the content into the processor as appropriate. The electronic control device 2 may be formed integrally with the output device 3 (built into the output device 3), or may be provided separately from the output device 3.

[0015] The output device 3 is a device that displays information about the vehicle, and is, for example, a liquid crystal display, an organic EL (Electro-Luminescence) display, or a projector. All information displayed on the output device 3 is controlled by the electronic control device 2. The shape of the information display area on the output device 3 is not particularly limited, but is, for example, rectangular. The output device 3 is placed in a position that is easily visible to the driver, such as in front of the driver (in front of the steering wheel) or in the front center of the vehicle compartment (forward between the driver's seat and the passenger seat). As ancillary devices of the output device 3, a touch panel device that detects touch operations on a screen, an input device provided with a keyboard, physical buttons, or touchpad, a gaze detection device that detects gaze, a gesture reading device that detects gesture operations, etc. may be provided.

[0016] A mode selector switch 6 and a main switch 7 are connected to the display device 1. The mode selector switch 6 is a toggle switch for switching the display mode (display manner) of information displayed on the output device 3. The main switch 7 is an on / off switch for switching the connection / disconnection state of the vehicle's main power supply. The mode selector switch 6 and the main switch 7 may be physical switches provided in the vehicle cabin, or may be virtual switches displayed on the output device 3 or another display. When these switches are virtual switches, an operation detection means for detecting a pressing operation or a gesture operation on the virtual switch may be used in combination.

[0017] [2. Display mode details] At least two display modes (display modes) with different layouts (display modes) are prepared as display modes (display modes) for information displayed on the output device 3. One of these modes is called a first display mode 4, and the other mode is called a second display mode 5. The user can select any of these modes. In this embodiment, the first display mode 4 and the second display mode 5 are switched between by operating the mode selector switch 6. Furthermore, when the main power supply of the vehicle is turned on by operating the main switch 7, the display mode before the main power supply was turned off (the most recent display mode) is restored.

[0018] The first display mode 4 is a mode that provides a standard meter display appearance, and is a mode that displays vehicle speed information, output information, and content information. The second display mode 5 is a mode that enhances the display of content information. In the second display mode 5, the display area for content information is enlarged and the display area for vehicle speed information is reduced compared to the first display mode 4.

[0019] [2-1. Primary display mode] 2 is a diagram showing the screen configuration of the first display mode 4. The first display mode 4 has at least a first content display unit 10, a first output display unit 11, and a second output display unit 12. The first content display unit 10 is a part that displays information (content information) that indicates the running state of the vehicle or the operating state of on-board equipment. The first content display unit 10 can display information such as letters, numbers, pictograms, images, and videos (moving images).

[0020] The first output display unit 11 is a component that represents the vehicle output (first output) by the length of a bar graph drawn therein. Hereinafter, the term "output" may be understood as "first output." The first output display unit 11 displays at least a bar graph representing the height of the output, and preferably displays a scale, pointer, numerical value, unit, etc. that indicate the length. The first output display unit 11 is disposed in an area that includes at least the area above the first content display unit 10. The first output display unit 11 shown in FIG. 2 is disposed to the left and above the first content display unit 10. The overall shape of the first output display unit 11 may be similar to the shape of the letter L rotated 90 degrees clockwise (a rotated L-shape). Alternatively, it may be similar to the shape of a rectangle with the bottom and right sides removed from the four sides that make up the outline of the rectangle.

[0021] The second output display unit 12 is a component that displays the vehicle speed as a second output of the vehicle using the length of a bar graph drawn therein. Hereinafter, the term "vehicle speed" may be understood as the term "second output." The second output includes not only vehicle speed but also other outputs (e.g., the first output). The second output display unit 12 displays at least a bar graph representing the vehicle speed, and preferably displays a scale, pointer, numerical value, unit, etc., that serve as an indicator of the length. The second output display unit 12 is disposed on the outer periphery of the first content display unit 10 and the first output display unit 11, in a range that includes at least the left and right sides and above the first content display unit 10 and the first output display unit 11. The overall shape of the second output display unit 12 may resemble an upside-down U (an inverted U-shape), as shown in FIG. 2 . Alternatively, the second output display unit 12 may resemble a rectangle with only the bottom side removed from the four sides that make up the rectangle.

[0022] The first display mode 4 shown in FIG. 2 has a first remaining capacity display unit 13 and a first numeric vehicle speed display unit 14. The first remaining capacity display unit 13 is a component that displays information indicating the remaining capacity of a battery mounted on the vehicle. The first remaining capacity display unit 13 is disposed to the left of the first content display unit 10, adjacent to and below the first output display unit 11. In a hybrid vehicle equipped with a traction motor and an engine with a generator, the remaining capacity of the drive battery (high-voltage battery) is displayed on the first remaining capacity display unit 13. The magnitude of the remaining capacity may be expressed concretely using a numerical value or a percentage, or may be expressed abstractly using the color or shape of an icon. In an engine vehicle not equipped with a battery for driving the vehicle, the remaining capacity of the auxiliary battery may be displayed on the first remaining capacity display unit 13, or the display on the first remaining capacity display unit 13 itself may be omitted.

[0023] The first numeric vehicle speed display unit 14 is a component that displays the vehicle speed in numbers, separate from the second output display unit 12. The unit of vehicle speed displayed here may be set in advance according to the destination of the vehicle, or may be set arbitrarily by the user. Specific examples of vehicle speed units include km / h (kilometers per hour), mph (miles per hour), and m / s (meters per second). The user may also be able to arbitrarily select whether the display on the first numeric vehicle speed display unit 14 is on or off.

[0024] 4(A) and (B) are diagrams showing specific examples of the first display mode 4. Fig. 4(A) is a display example for an engine vehicle, and Fig. 4(B) is a display example for a hybrid vehicle equipped with a motor that performs power running and regenerative power generation. Both display examples include a first content display unit 10, a first output display unit 11, a second output display unit 12, a first remaining capacity display unit 13, and a first numeric vehicle speed display unit 14. In addition to these, the time, outside temperature, name of the driving mode, shift position, mileage, etc. are displayed, as well as icons for selecting the type of information to be displayed in the first content display unit 10 and display settings.

[0025] [2-2. Second display mode] 3 is a diagram showing the screen configuration of second display mode 5. Second display mode 5 has at least a second content display unit 15, a third output display unit 16, and a second numeric vehicle speed display unit 17. The second content display unit 15 is a section that displays information indicating the vehicle's running state or the operating state of on-board equipment, and has a larger area than the first content display unit 10. The second content display unit 15 may display the same (or substantially the same) information as that displayed in the first content display unit 10, or may display a detailed image illustrating the details of that information.

[0026] Similar to the first output display unit 11, the third output display unit 16 is a component that represents the vehicle output by the length of a bar graph drawn therein. The third output display unit 16 displays at least a bar graph representing the height of the output, and preferably displays a scale, pointer, numerical value, unit, etc. that serve as an indicator of the length. The third output display unit 16 is disposed in a range that includes at least the area below the second content display unit 15. The third output display unit 16 shown in FIG. 3 is disposed approximately horizontally along the bottom side of the second content display unit 15.

[0027] The second numeric vehicle speed display unit 17 is a part that indicates the vehicle speed in numbers, similar to the first numeric vehicle speed display unit 14. The unit of vehicle speed displayed here may be set in advance according to the destination of the vehicle, or may be set arbitrarily by the user. In the second display mode 5, the second numeric vehicle speed display unit 17 is always displayed, and the user cannot select whether the display of the second numeric vehicle speed display unit 17 is on or off.

[0028] The second display mode 5 shown in FIG. 3 has a second remaining capacity display unit 18. Similar to the first remaining capacity display unit 13, the second remaining capacity display unit 18 is a component that displays information indicating the remaining capacity of the battery mounted on the vehicle. The second remaining capacity display unit 18 is disposed below the second content display unit 15 and adjacent to the left of the third output display unit 16. In a hybrid vehicle, the remaining capacity of the drive battery is displayed on the second remaining capacity display unit 18. In an engine vehicle, the remaining capacity of the auxiliary battery may be displayed on the second remaining capacity display unit 18, or the display on the second remaining capacity display unit 18 itself may be omitted.

[0029] 5(A) and (B) are diagrams showing specific examples of the second display mode 5. Fig. 5(A) is a display example for an engine vehicle, and Fig. 5(B) is a display example for a hybrid vehicle. Both display examples include a second content display unit 15, a third output display unit 16, a second numeric vehicle speed display unit 17, and a second remaining capacity display unit 18. In addition to these, the time, outside temperature, name of the driving mode, shift position, mileage, etc. are displayed, as well as icons for selecting the type of information to be displayed in the second content display unit 15 and display settings.

[0030] [2-3. First output display section, first remaining capacity display section] 6(A) and (B) are diagrams showing specific examples of the first output display unit 11 and the first remaining capacity display unit 13. Fig. 6(A) is a display example for an engine vehicle, and Fig. 6(B) is a display example for a hybrid vehicle. The first output display unit 11 has a first output left area 20 and a first output upper area 21. The first output left area 20 is a portion extending in the vertical direction on the left side of the first content display unit 10. The first output upper area 21 is a portion extending in the right direction from the upper end of the first output left area 20 above the first content display unit 10. The first output left area 20 is an area that represents a relatively lower output compared to the first output upper area 21.

[0031] In the display example of FIG. 6(A), the origin (the scale mark indicating that the output is 0) of the bar graph representing the output level is located near the bottom end of the first left output area 20. As the output increases, the bar graph extends upward from the origin along the extension direction of the first left output area 20. After the bar graph reaches near the top end of the first left output area 20, if the output increases further, it extends to the right along the extension direction of the first upper output area 21.

[0032] In the display example of Fig. 6(B), first output display unit 11 has a power region and a charge region. In addition, in the display example of Fig. 6(B), the origin of the bar graph that forms the boundary between the power region and the charge region is located near the midpoint between the left end and the center of first output upper region 21. The power region is a region that represents the power consumption of the motor, and the charge region is a region that represents the charging power of the drive battery.

[0033] When the output value is positive (during powering), the bar graph extends from the origin to the right along the extension direction of the first output upper region 21 as the absolute value of the output increases. On the other hand, when the output value is negative (during regeneration), the bar graph extends from the origin to the left along the extension direction of the first output upper region 21 as the output decreases (the absolute value of the output increases). After the bar graph reaches the vicinity of the left end of the first output upper region 21, if the output further decreases (the absolute value of the output increases), it extends downward along the extension direction of the first output left region 20.

[0034] The first remaining capacity display section 13 is disposed adjacent to and below the first left output area 20 (charge area). In the display example of Figures 6(A) and (B), an image of a dry cell shape including a bar graph that expands in proportion to the remaining capacity is displayed. The origin of this bar graph is disposed near the bottom end of the first remaining capacity display section 13, and the bar graph expands upward from the origin as the remaining capacity increases.

[0035] In the display example of FIG. 6(A), the extension direction of the bar graph displayed in first remaining capacity display unit 13 matches the extension direction of the bar graph displayed in first output left area 20. This makes it easier to intuitively understand the output of the auxiliary battery and the engine. Also, in the display example of FIG. 6(B), the extension direction of the output during regeneration displayed in first output display unit 11 (the direction in which the negative output value increases) is opposite to the extension direction of the bar graph displayed in first remaining capacity display unit 13. This makes it easier to intuitively understand that regenerative power is being charged to the drive battery.

[0036] [2-4. Third output display section, second remaining capacity display section] 7(A) and (B) are diagrams showing specific examples of the third output display unit 16 and the second remaining capacity display unit 18. Fig. 7(A) is a display example for an engine vehicle, and Fig. 7(B) is a display example for a hybrid vehicle. In the display example of Fig. 7(A), the origin of the bar graph is located near the left end of third output display unit 16. As the output increases, the bar graph extends from the origin to the right along the extension direction of third output display unit 16.

[0037] In the display example of Fig. 7(B), the origin of the bar graph is located near the midpoint between the left end and the center of the third output display section 16. When the output value is positive (powering), the bar graph extends from the origin to the right as the absolute value of the output increases. On the other hand, when the output value is negative (regenerating), the bar graph extends from the origin to the left as the output decreases (the absolute value of the output increases).

[0038] The second remaining capacity display unit 18 is disposed adjacent to the left of the third output display unit 16. In the display example of Figures 7(A) and (B), an image of a dry cell shape including a bar graph that expands in proportion to the remaining capacity is displayed. The origin of this bar graph is disposed near the left end of the second remaining capacity display unit 18, and the bar graph expands further to the right from the origin as the remaining capacity increases.

[0039] In the display example of Fig. 7(A), the extension direction of the bar graph displayed in second remaining capacity display unit 18 matches the extension direction of the bar graph displayed in third output display unit 16. This makes it easier to intuitively understand the output of the auxiliary battery and the engine. Also, in the display example of Fig. 7(B), the extension direction of the output during regeneration displayed in third output display unit 16 (the direction in which the negative output value increases) is opposite to the extension direction of the bar graph displayed in second remaining capacity display unit 18. This makes it easier to intuitively understand that regenerative power is being charged to the drive battery.

[0040] [2-5.Second output display section] FIG. 8 is a diagram showing a specific example of the second output display unit 12. The second output display unit 12 has a second output left area 22, a second output upper area 23, and a second output right area 24. The second output left area 22 is a region extending in the vertical direction to the left of the first output display unit 11 (e.g., the first output left area 20). The second output upper area 23 is a region extending rightward from the upper end of the second output left area 22 above the first output display unit 11 (e.g., the first output upper area 21). The second output right area 24 is a region extending downward from the right end of the second output upper area 23 to the right of the first output display unit 11 or the first content display unit 10. The second output left area 22 is a region representing a relatively low vehicle speed compared to the second output upper area 23 and the second output right area 24. The second output left area 22 and the second output right area 24 have their lower ends aligned in the vertical direction.

[0041] In the display example of FIG. 8 , a first frame line 51, a bar graph 53, a scale 54, a pointer 55, and an indicator number 56 are displayed on the second output display unit 12. The bar graph 53 is a bar-shaped figure whose length corresponds to the vehicle speed, and the shape of the expansion / contraction region is set so that it has an inverted U-shape when fully expanded. The origin of the bar graph 53 (the scale representing a vehicle speed of 0) is located near the bottom end of the second output left region 22. As the vehicle speed increases, the bar graph 53 expands upward from the origin along the extension direction of the second output left region 22. After the bar graph 53 reaches near the top end of the second output left region 22, if the vehicle speed further increases, the bar graph 53 expands rightward along the extension direction of the second output upper region 23. After the bar graph 53 reaches near the right end of the second output upper region 23, if the vehicle speed further increases, the bar graph 53 expands downward along the extension direction of the second output right region 24.

[0042] The first frame line 51 is a frame line having a shape corresponding to an area in which at least some output information is displayed. In this embodiment, the first frame line 51 is a line drawn on the outer periphery of the screen of the second output display unit 12, forming the outer periphery of the outline of the bar graph 53 and shaped like an inverted U-shaped gate. This first frame line 51 is marked with scales 54 that indicate the length of the bar graph 53. The scales 54 are multiple marks marked at approximately equal intervals from the origin of the bar graph 53, and are arranged along the first frame line 51 to indicate regular speed intervals corresponding to, for example, 5 km / h or 10 km / h. The scales 54 shown in FIG. 8 include thick scales indicating that the vehicle speed value is a multiple of 10 and thin scales indicating that the vehicle speed value has a 5 digit. The indicator numbers 56 indicate the specific vehicle speed value represented by each scale 54.

[0043] The pointer 55 is a mark added to highlight the position of the top of the bar graph 53, and is drawn as a bar longer than the width of the bar graph 53. The position of the pointer 55 (the position of the pointer 55 in the extension direction of the first frame line 51) moves in accordance with the expansion and contraction of the bar graph 53. The user can easily grasp the vehicle speed value (the length of the bar graph 53) by reading the relative position of the pointer 55 with respect to the scale 54 and referring to the indicator number 56 displayed near the pointer 55.

[0044] In the display examples of FIGS. 6(A) and 8, the extension direction of the bar graph 53 inside the second output display unit 12 (second output left area 22) matches the extension direction of the bar graph inside the first output display unit 11 (first output left area 20). This makes it easier to intuitively understand the vehicle speed and engine output state. Similarly, in the display examples of FIGS. 6(B) and 8, the extension direction of the bar graph 53 inside the second output display unit 12 (second output upper area 23) matches the extension direction of the bar graph (during powering) inside the first output display unit 11 (first output upper area 21). This makes it easier to intuitively understand the vehicle speed and motor output state.

[0045] [2-6. First numerical vehicle speed display section, second numerical vehicle speed display section] Fig. 9(A) is a diagram showing a specific example of first numeric vehicle speed display unit 14, and Fig. 9(B) is a diagram showing a specific example of second numeric vehicle speed display unit 17. First numeric vehicle speed display unit 14 has a numeric display area 25 that displays at least the vehicle speed in numbers. In addition, first numeric vehicle speed display unit 14 shown in Fig. 9(A) also has a cruise control display area 26, a regulations display area 27, and a conversion value display area 28. The on / off display of cruise control display area 26, regulations display area 27, and conversion value display area 28 may be preset according to the destination of the vehicle, or may be selectable by the user.

[0046] Cruise control display area 26 is an area that displays information related to cruise control. Cruise control is a control that automatically increases or decreases vehicle speed without relying on driving operations, and includes, for example, constant speed driving control on expressways, automatic following control for a preceding vehicle, and control for maintaining a distance between vehicles. Specifically, telltales (icons, marks) that indicate that cruise control is being performed, telltales that indicate the set vehicle speed during constant speed driving control, and telltales that indicate that a preceding vehicle that should be followed is present and that a predetermined distance between vehicles is maintained are displayed. The legal regulations display area 27 is an area that displays information about the vehicle speed that complies with the legal regulations. For example, the legal maximum speed and the designated speed for each section of the road on which the vehicle is traveling are displayed in the legal regulations display area 27.

[0047] The converted value display area 28 is an area for displaying a value obtained by converting the vehicle speed displayed on the second output display unit 12 or the numeric display area 25 into another unit. For example, when the vehicle speed displayed on the second output display unit 12 or the numeric display area 25 is in km / h (kilometers per hour), a value converted into a different unit (e.g., mph (miles per hour), m / s (meters per second)) is displayed in the converted value display area 28. Note that the user may be allowed to select any unit to be converted here.

[0048] 9(B) has a numeric display area 25, a cruise control display area 26, a regulations display area 27, and a conversion value display area 28. The content displayed in each of these areas is the same as that displayed in the first numeric vehicle speed display area 14; only the display layout is different. This prevents the display content of the first numeric vehicle speed display area 14 and the second numeric vehicle speed display area 17 from being lost when the display mode is switched between the first display mode 4 and the second display mode 5.

[0049] [2-7. First content display section] FIG. 10(A) is a diagram showing the screen configuration of the first content display section 10, and FIGS. 10(B) to 10(E) are diagrams showing specific examples of the first content display section 10. As shown in FIG. The first content display unit 10 has a first title display area 30 where the title of the information is displayed, a first content display area 31 where the content of the information is displayed, and a first boundary line 32 that separates these areas. The first boundary line 32 is a line that extends horizontally and separates the first title display area 30 and the first content display area 31 in the vertical direction. The display positions and area sizes of the first title display area 30, the first content display area 31, and the first boundary line 32 do not change regardless of the content.

[0050] 10(B) to (D), specific examples of headings displayed in the first heading display area 30 include "Drive Computer," "Energy Flow," and "Various Settings." Contents corresponding to the heading "Drive Computer" include information on average fuel consumption and average vehicle speed as shown in FIG. 10(B), as well as instantaneous fuel consumption, electricity consumption, driving time, estimated cruising range, and the like.

[0051] The heading "Energy Flow" is the title of a diagram showing the state of energy transfer between the engine with generator, the drive battery, and the drive wheels. In the display example shown in Fig. 10(C), the engine with generator, the drive battery, and the drive wheels are each represented by a simple icon, and the state of energy (driving force or electric power) transfer is represented by an arrow. In addition, the contents corresponding to the heading "Various Settings" include an item for selecting the display mode (display manner) and an item for selecting whether to turn the display on or off on the first numeric vehicle speed display unit 14.

[0052] As shown in FIG. 10(E), the first content display unit 10 has a function for displaying the positional relationship between the vehicle and surrounding vehicles or obstacles using a first perspective view that simulates a state in which the vehicle is viewed from above behind the vehicle. A first horizon line 33 drawn between the ground and the sky in the first perspective view is displayed in the same shape and at the same position as the first boundary line 32 when other information is displayed. In other words, even if the information displayed on the first content display unit 10 is switched, the first boundary line 32 and the first horizon line 33 do not change. Note that the first boundary line 32 and the first horizon line 33 do not need to have exactly the same shape. Furthermore, the title of the first perspective view may be, for example, "ADAS (Advanced Driver Assistance System) Information."

[0053] [2-8. Second content display section] FIG. 11(A) is a diagram showing the screen configuration of the second content display section 15, and FIGS. 11(B) to 11(E) are diagrams showing specific examples of the second content display section 15. As shown in FIG. The second content display unit 15 has an area at least larger than that of the first content display unit 10. The second content display unit 15 shown in Fig. 11(A) has a shape that expands upward from the position of the first content display unit 10 to the area where the first output display unit 11 and the second output display unit 12 were located.

[0054] The second content display unit 15 has a second title display area 34 where the title of the information is displayed, a second content display area 35 where the content of the information is displayed, and a second boundary line 36 that separates these areas. The second boundary line 36 is a line that extends horizontally and separates the second title display area 34 and the second content display area 35 in the vertical direction. The display positions and area sizes of the second title display area 34, the second content display area 35, and the second boundary line 36 do not change regardless of the content.

[0055] Regarding the relationship between the first content display section 10 and the second content display section 15, the second title display section 34 is disposed above the first title display section 30, and the second boundary line 36 is disposed above the first boundary line 32. The second content display section 35 is formed to be larger in size than the first content display section 31, and is formed, for example, in a shape that expands the first content display section 31 upward, leftward, and rightward.

[0056] The second content display unit 15 is capable of displaying at least the same information as the first content display unit 10. Preferably, since the second content display unit 15 has a larger area than the first content display unit 10, larger characters and images are displayed than in the first content display unit 10, or more information or more detailed information is displayed than in the first content display unit 10. For example, the display example in FIG. 11(B) (content corresponding to the title "Drive Computer") is an enlarged version of the display content in FIG. 10(B).

[0057] The display example of Fig. 11(C) (content corresponding to the title "Energy Flow") is a detailed image 37 illustrating the details of the information shown in Fig. 10(C). In this detailed image, the positions of the engine with generator, drive battery, drive motor, and drive wheels mounted on the vehicle are shown in perspective views, and the movement of energy (driving force or electric power) is expressed by arrows.

[0058] 11(D) (contents corresponding to the title "Various Settings"), in addition to the information shown in Fig. 10(D), detailed images 38 are added to supplement the information written in the second content display area 35. For example, when an item for selecting a display mode is selected among the setting items displayed in the second content display area 35, detailed images 38 that are reduced versions of the layout of each display mode are displayed.

[0059] 11(E), the second content display unit 15 has a function of displaying the positional relationship between the vehicle and surrounding vehicles or obstacles using a second perspective view that simulates a view of the vehicle from above behind the vehicle. The viewpoint position in the second perspective view is preferably set to a higher position than the viewpoint position in the first perspective view. This improves the readability of the second perspective view and provides a better view of a wider area.

[0060] The second horizon 39 drawn between the ground and the sky in the second perspective view is displayed in the same shape and at the same position as the second boundary line 36 when other information is displayed. In other words, even if the information displayed in the second content display unit 15 is switched, the second boundary line 36 and the second horizon 39 do not change. Note that the second boundary line 36 and the second horizon 39 do not have to have exactly the same shape.

[0061] [3. Animation] [3-1. When switching modes] 12(A) to 12(J) are diagrams for explaining animations (moving images) displayed when the display mode is switched. Each of FIGS. 12(A) to 12(J) sequentially shows the screen contents of one cut (one frame) included in a series of animations displayed when switching from first display mode 4 to second display mode 5. Note that the images actually displayed on the output device 3 are assumed to be equivalent to the images shown in each of FIGS. 12(A) to 12(J) with black and white reversed (images with a black background and images and text in bright white or color). Furthermore, when switching from second display mode 5 to first display mode 4, each cut is played back in reverse order.

[0062] When switching from the first display mode 4 to the second display mode 5, the display device 1 of this embodiment sequentially plays back and displays a first transition moving image 61, a second transition moving image 62, and a third transition moving image 63. FIG. 12(A) shows a screen in the first display mode 4, and FIGS. 12(B) and 12(C) show screens included in the first transition moving image 61. Also, FIGS. 12(D) and 12(E) show screens included in the second transition moving image 62, FIGS. 12(F) to 12(I) show screens included in the third transition moving image 63, and FIG. 12(H) shows a screen in the second display mode 5.

[0063] The first transition video 61 is an animation in which the first frame 51 displayed on the second output display unit 12 shrinks toward the center of the screen while decreasing the brightness of the display content other than the first frame 51. In the first transition video 61, the display content is gradually reduced toward the center of the screen, as shown in FIGS. 12(B) and 12(C). At this time, the brightness of elements other than the first frame 51 (e.g., the bar graph 53, scale 54, pointer 55, and indicator numeral 56 of the first content display unit 10, first output display unit 11, and second output display unit 12) is gradually reduced, and characters and images other than the first frame 51 are gradually displayed as if they are disappearing. By gradually hiding elements other than the first frame 51, the first transition video 61 creates the impression that the stage has been darkened and creates a sense of anticipation for a change in the screen. It is preferable that the display content of the first numeric vehicle speed display unit 14 is always clearly displayed.

[0064] The second transition video 62 is an animation in which, after the first frame line 51 in the first transition video 61 shrinks toward the center of the screen, multiple second frame lines 52 having a shape similar to the first frame line 51 are displayed in succession, sequentially shrinking toward the center of the screen. That is, in the second transition video 62, a video is played in which multiple second frame lines 52 appear one after another and move while repeatedly shrinking toward the center of the screen. The second frame lines 52 preferably have a shape similar to the first frame line 51, but they do not need to be strictly similar in shape as long as they are at least similar in shape to the first frame line 51. Each second frame line 52 is drawn shrinking toward the center of the screen, as indicated by the white arrow in FIG. 12(D).

[0065] As a result, the second transitional video 62 gives the user the sensation that the second frame line 52 is moving forward in a space drawn in one-point perspective (in other words, the user has a mysterious sensation that they are moving backward in a virtual tunnel). It is preferable that the display content of the first numeric vehicle speed display unit 14 is eventually taken over by the second numeric vehicle speed display unit 17 (when the display mode has completely shifted to the second display mode 5). Therefore, the display position of the first numeric vehicle speed display unit 14 may be gradually moved toward the intended display position of the second numeric vehicle speed display unit 17.

[0066] The third transition video 63 is an animation in which the second boundary line 36 is displayed, and a moving object 57, which is a shape obtained by deforming the second frame line 52 in the second transition video 62, is further shrunk toward the second boundary line 36 and disappears. In the third transition video 63, as shown in FIG. 12(F), for example, the second boundary line 36, which has the same shape as that displayed in the second content display unit 15 in the second display mode 5, is displayed in the same position as that displayed in the second content display unit 15. Next, as shown in FIG. 12(G), the second frame line 52, which has shrunk and moved toward the center of the screen, is transformed while rotating clockwise, and a moving object 57 having an abstract shape resembling a vehicle (for example, a shape resembling an oval frame) is drawn.

[0067] 12(H) and (I), the moving object 57 is rendered as it shrinks and moves toward a vanishing point on the second boundary line 36. This vanishing point is preferably located at the center of the second boundary line 36 in the horizontal direction. The position of the vanishing point may coincide with the center position of the shrinking movement of the second frame line 52 in the second transition video 62. The third transition video 63 gives the user a sense of loneliness, as if the second frame line 52 has transformed into the moving object 57 and then flown away forward. Further thereafter, as shown in FIG. 12(J), the second content display unit 15, the third output display unit 16, the second numeric vehicle speed display unit 17, etc. are displayed, completing the screen transition from the first display mode 4 to the second display mode 5.

[0068] 13(A) to 13(H) are diagrams illustrating a modified example of the animation (moving image) displayed when switching from the first display mode 4 to the second display mode 5. In this modified example, a fourth transition moving image 64 is played following the third transition moving image 63. Each of FIGS. 13(A) to 13(H) shows the contents of a single cut (one frame) included in a series of animations inserted between FIGS. 12(I) and 12(J). FIGS. 13(A) to 13(C) show images included in the third transition moving image 63, FIGS. 13(D) to 13(G) show images included in the fourth transition moving image 64, and FIG. 13(H) shows an image in the second display mode 5. Note that the images actually displayed on the output device 3 are assumed to be equivalent to the images shown in FIGS. 13(A) to 13(H) with inverted black and white (images with a black background and images and text in bright white or other colors).

[0069] The fourth transition video 64 is an animation that follows the third transition video 63 and displays a first light ray 58 that spreads horizontally from the point where the moving object 57 (a shape obtained by deforming the second frame line 52) disappears in the third transition video 63, along the second boundary line 36. As shown in FIGS. 13(A) to 13(C), the moving object 57 moves while shrinking so as to disappear, for example, toward the center in the left-right direction of the second boundary line 36.

[0070] Next, as shown in Fig. 13(D), a sparkling dot of light is displayed near the vanishing point of moving object 57. This dot of light, for example, is surrounded by multiple tiny bright dots and spreads left and right from the vanishing point of moving object 57. As a result, a shining line (first light ray 58) is drawn along second boundary line 36, as shown in Figs. 13(E) and (F). Fourth transition video 64 gives the user a sense of exhilaration, like the light of dawn spreading along the horizon, and a sense of anticipation, like the dawn of a new day.

[0071] After that, when almost the entire second boundary line 36 is covered by the first light beam 58 and emits light, the brightness of the first light beam 58 is gradually reduced. Furthermore, as shown in FIG. 13(G), the brightness of the second content display unit 15, the third output display unit 16, the second numeric vehicle speed display unit 17, etc. gradually increases, and the screen of second display mode 5 is displayed as if it is gradually emerging from the darkness. Further thereafter, as shown in FIG. 13(H), the second content display unit 15, the third output display unit 16, the second numeric vehicle speed display unit 17, etc. are completely displayed, and the screen transition from first display mode 4 to second display mode 5 is completed.

[0072] [3-2. When the vehicle's main power is turned on] 14(A) to 14(H) are diagrams illustrating animations (moving images) that are displayed when the main power supply of a vehicle is turned on. The display mode immediately after the main power supply is turned on is the same as the display mode immediately before the main power supply is turned off, and may be either first display mode 4 or second display mode 5. In this embodiment, the case where first display mode 4 is selected will be described. Each of FIGS. 14(A) to 14(H) shows the contents of a single cut (one frame) included in a series of animations. Note that the images actually displayed on the output device 3 are assumed to be equivalent to the images shown in each of FIGS. 14(A) to 14(H) with inverted black and white (images with a black background and images and text in bright white or other colors).

[0073] When the main power supply of the vehicle is turned on, the display device 1 of this embodiment sequentially plays back and displays a first startup video 71, a second startup video 72, and a third startup video 73. Figures 14(A) to 14(C) show screens included in the first startup video 71, and Figures 14(D) to 14(F) show screens included in the second startup video 72. Figure 14(G) shows a screen included in the third startup video 73, and Figure 14(H) shows a screen in first display mode 4.

[0074] The first startup video 71 is an animation that displays an image of a vehicle approaching with its headlights on. The image displayed in the first startup video 71 is an image of the vehicle photographed (or rendered as 3D CG) at an angle of view and from a shooting direction that allows the headlights to be seen. Specific examples of this image include an image of a moving vehicle viewed from above, or an image of an approaching vehicle viewed from the road ahead. The first startup video 71 acts to make the user anticipate changes to the screen as the vehicle approaches.

[0075] 14(A) to 14(C) is an image showing the front design of the vehicle as it turns forward, and is an image of the vehicle photographed almost horizontally from the outside of the turning course. By using an image of the vehicle turning while moving forward in this way, the change in the screen displayed on the output device 3 makes a strong impression on the user, and also implicitly notifies the user that the vehicle is starting up (that is, that the vehicle is about to enter a standby state where it can start driving).

[0076] Furthermore, the first startup video 71 may initially display an image in which only the headlights of the vehicle are visible and no body of the vehicle is visible, and then display an image of the vehicle turning forward while the brightness of the body of the vehicle is increased. For example, as shown in Figure 14(A), a vehicle may appear from the darkness with only the light from the headlights visible, and then, as shown in Figures 14(B) and (C), the brightness of the body of the vehicle may gradually increase so that the outline of the vehicle becomes visible. This type of presentation creates an unexpected and mysterious atmosphere, as if the vehicle had suddenly appeared out of the darkness.

[0077] The second startup video 72 is an animation that displays a second ray of light 59 extending horizontally from the vehicle's headlight displayed on the screen. For example, as shown in FIG. 14(D), a sparkling dot of light is first displayed near the vehicle's headlight. This dot of light, surrounded by multiple tiny bright spots, extends horizontally to the left and right of the headlight. This results in the depiction of a second ray of light 59 extending horizontally from the headlight, as shown in FIGS. 14(E) and 14(F). By extending the light from the headlight horizontally as the second ray of light 59, the second startup video 72 creates a sense of anticipation in the user, as if a new world is opening up, and a thrilling feeling for the scene change.

[0078] Compared to the image of the vehicle approaching in the first startup video 71, the second startup video 72 shown in FIGS. 14(D) to (F) displays an image of the vehicle accelerating toward the front of the screen and moving off the screen, superimposed with the second light ray 59. By accelerating the movement of the vehicle on the screen in the second startup video 72 compared to the first startup video 71, the user is more impressed with the sense of speed and quality of the vehicle's startup sequence. Furthermore, the position of the second light ray 59 on the screen is fixed near the headlight in FIG. 14(D). Therefore, in FIG. 14(E), the second light ray 59 is displayed at a position shifted from the vicinity of the headlight. This leaves a strong impression on the user of the sparkling second light ray 59, leaving a lingering impression like an afterimage of the headlight.

[0079] The third startup video 73 is an animation that displays the first boundary line 32 or the second boundary line 36 at the same position as the second light ray 59. If the display mode immediately after the main power is turned on is first display mode 4, the first boundary line 32 is displayed at the same position as the second light ray 59. If the display mode immediately after the main power is turned on is second display mode 5, the second boundary line 36 is displayed at the same position as the second light ray 59. In other words, the second light ray 59 of the second startup video 72 is displayed at the position where the first boundary line 32 or the second boundary line 36 is intended to be displayed in the third startup video 73. For example, as shown in FIG. 14(G), the first boundary line 32 is drawn at a position overlapping with the second light ray 59. The third startup video 73 impresses the user with the unexpectedness of the second light ray 59 transforming directly into the first boundary line 32 and the stability of the position of the first boundary line 32.

[0080] The third startup video 73 shown in Fig. 14(G) displays an image in which the brightness of the content information gradually increases while maintaining the position of the first boundary line 32. That is, the content information displayed in the first content display unit 10 is displayed so that it gradually emerges from the darkness. At this time, the brightness of display contents other than those in the first content display unit 10 may also be similarly gradually increased. Thereafter, as shown in Fig. 14(H), the first content display unit 10, first output display unit 11, second output display unit 12, etc. are fully displayed, completing the display of first display mode 4.

[0081] [4. Effects] (1) The display device 1 of this embodiment displays content information that indicates the running state of the vehicle or the operating state of on-board equipment, and output information that indicates the output of the vehicle, and is switchable between a first display mode 4 and a second display mode 5, which differ in the display manner of the content information and the output information. In the first display mode 4, a first frame line 51 having a shape that corresponds to at least the area in which the output information is displayed is displayed.

[0082] Furthermore, when switching from the first display mode 4 to the second display mode 5, the display device 1 sequentially plays back a first transition moving image 61 and a second transition moving image 62. The first transition moving image 61 is a moving image in which the first frame line 51 shrinks toward the center of the screen while decreasing the brightness of the display content other than the first frame line 51. The second transition moving image 62 is a moving image in which, after the first frame line 51 shrinks toward the center of the screen, a plurality of second frame lines 52 similar to the first frame line 51 are continuously displayed so as to shrink sequentially toward the center of the screen.

[0083] This configuration allows the display mode of the content information and output information (including vehicle speed information) to change smoothly and naturally, improving screen visibility. Furthermore, when switching from the first display mode 4 to the second display mode 5, the first transition video 61 and the second transition video 62 are played in sequence, improving the dramatic effect. For example, the first transition video 61 can heighten the user's sense of anticipation for the scene change caused by the stage going dark. Furthermore, the second transition video 62 can provide the user with a mysterious and novel sensation, as if the user were reversing through a virtual tunnel. This increases the excitement associated with switching display modes, creates a sporty and stylish appearance, and exudes a sophisticated and luxurious feel. Therefore, the user experience can be improved.

[0084] (2) In the first display mode 4 of this embodiment, a first boundary line 32 that vertically divides the title and content of the content information is displayed. Similarly, in the second display mode 5, a second boundary line 36 that vertically divides the title and content of the content information is displayed. Furthermore, when switching from the first display mode 4 to the second display mode 5, the display device 1 can play a third transition moving image 63 following the second transition moving image 62. The third transition moving image 63 displays the second boundary line 36 and causes a moving object 57, which is a shape obtained by deforming the second frame line 52 in the second transition moving image 62, to shrink further toward the second boundary line 36 and disappear.

[0085] In this way, the dramatic effect can be further improved by sequentially playing the first transition video 61, the second transition video 62, and the third transition video 63. For example, the third transition video 63 can give the user a sense of loneliness and tranquility, as if the moving object 57, formed by deforming the second frame line 52, has flown away forward, further enhancing the sophisticated and luxurious impression associated with switching the display mode. This can therefore improve the user experience.

[0086] (3) In this embodiment, when switching from the first display mode 4 to the second display mode 5, the fourth transition video 64 may be displayed following the third transition video 63. The fourth transition video 64 is a video that displays a first light ray 58 that spreads horizontally from the point where the moving object 57 (figure) disappears along the second boundary line 36. In this way, by displaying the fourth transition video 64 following the third transition video 63, the user can be given a sense of exhilaration and anticipation, like dawn, and the sophisticated impression and sense of luxury associated with the display mode switch can be further enhanced. This can improve the user experience.

[0087] (4) The first display mode 4 of this embodiment is provided with a second output display unit 12 that includes a first frame line 51 and indicates vehicle speed by the length of a bar graph 53, a first numeric vehicle speed display unit 14 that indicates vehicle speed in numbers separately from the second output display unit 12, and a first content display unit 10 that includes a first boundary line 32 and displays content information. The second display mode 5 is provided with a second numeric vehicle speed display unit 17 that indicates vehicle speed in numbers and a second content display unit 15 that includes a second boundary line 36 and displays content information.

[0088] When switching from the first display mode 4 to the second display mode 5, the bar graph 53 on the second output display unit 12 is displayed with its brightness gradually decreasing. This enhances the dramatic effect of the displayed content disappearing. On the other hand, by displaying the first numeric vehicle speed display unit 14 separately from the second output display unit 12, vehicle speed information can be presented to the user even when the bar graph 53 is not visible. Furthermore, by providing the first content display unit 10 and the second content display unit 15, content information can be displayed in either display mode. This improves the user experience.

[0089] (5) The display content of the first numeric vehicle speed display unit 14 can be set to be the same as the display content of the second numeric vehicle speed display unit 17. In this case, it is preferable that the display content of the first numeric vehicle speed display unit 14 or the second numeric vehicle speed display unit 17 continues to be displayed at all times when switching from the first display mode 4 to the second display mode 5. For example, it is preferable that the display content of the first numeric vehicle speed display unit 14 is taken over to the second numeric vehicle speed display unit 17 when the display mode is completely switched to the second display mode 5.

[0090] With this configuration, vehicle speed information can be displayed at all times during the process of switching from the first display mode 4 to the second display mode 5. The display position of the first numeric vehicle speed display unit 14 may be gradually moved toward the display position of the second numeric vehicle speed display unit 17. This makes it less likely that the user will lose track of where the vehicle speed information has moved before and after switching from the first display mode 4 to the second display mode 5, greatly improving the readability of information and the convenience of the display device 1.

[0091] (6) As shown in Fig. 2, the second output display unit 12 of this embodiment can be arranged on the outer periphery of the first content display unit 10 in a range that includes at least the left and right sides and the top of the first content display unit 10. Also, as shown in Fig. 8, the first frame line 51 is a line drawn on the outer periphery of the second output display unit 12, and is a line on which a scale 54 indicating the length of a bar graph 53 is marked.

[0092] When switching from the first display mode 4 to the second display mode 5 in which the second output display unit 12 is displayed, the bar graph 53 and the scale 54 are darkened while the first frame line 51 remains visible, thereby enhancing the dramatic effect. In addition, since the overall shape of the first frame line 51 resembles a gate, the second transition video 62 provides the user with a mysterious sensation as if the user is retreating through a virtual tunnel. This creates a sporty and stylish look, while also creating a sophisticated and luxurious impression. This improves the user experience.

[0093] (7) When the main power supply of a vehicle equipped with the display device 1 is turned on, the display device 1 of this embodiment sequentially plays a first startup video 71, a second startup video 72, and a third startup video 73. The first startup video 71 is a video that displays an image of a vehicle approaching with its headlights on. The second startup video 72 is a video that displays a second light ray 59 extending horizontally from the vehicle's headlights. The third startup video 73 is a video that displays the first boundary line 32 (or the second boundary line 36) in the same position as the second light ray 59.

[0094] In this way, by displaying the first boundary line 32 (or the second boundary line 36) at the same position as the second light ray 59 of the second startup video 72, the screen display mode can be naturally guided to the first display mode 4 or the second display mode 5, improving the user experience. For example, the first startup video 71 can make the user anticipate a change in the screen as the vehicle approaches, clearly indicating to the user that the vehicle startup sequence has begun. Furthermore, the second startup video 72 can provide the user with a sense of anticipation, as if a new world is about to open up, by extending the second light ray 59 horizontally. Furthermore, the third startup video 73 can impress upon the user the unexpectedness of the second light ray 59 directly changing into the first boundary line 32 and the stability of the position of the first boundary line 32.

[0095] (8) In this embodiment, the first startup video 71 displays an image showing the front design of the vehicle as it turns forward. The second startup video 72 displays an image of the vehicle moving toward the front of the screen, accelerating more rapidly than when it approached in the first startup video 71, and moving off the screen, superimposed with the second light ray 59. The third startup video 73 displays an image that increases the brightness of the content information while maintaining the position of the first boundary line 32 (or the second boundary line 36).

[0096] This configuration enhances the visual effect of the screen and further improves the user experience. For example, the first startup video 71 uses an image of a vehicle moving forward and turning, giving the user the impression that the vehicle is making an effort to enter standby mode of its own accord. The second startup video 72 accelerates the movement of the vehicle displayed on the screen, giving the user a strong impression of the speed and high quality of the vehicle's startup sequence. The third startup video 73 makes it appear as if the first content display unit 10 is emerging from the darkness without disrupting the overall layout defined by the first boundary line 32 (or the second boundary line 36), thereby creating a sophisticated and luxurious impression.

[0097] (9) In this embodiment, the first startup video 71 first displays an image in which only the headlights of the vehicle are visible, with no visible body, as shown in FIG. 14(A). Next, as shown in FIGS. 14(B) and 14(C), an image of the vehicle turning forward is displayed while the brightness of the body increases. This effect creates a sense of surprise and mystery, as if the vehicle suddenly appeared out of the darkness. This improves the dramatic effect associated with turning on the main power supply, thereby improving the user experience.

[0098] [5. Other] The above-described embodiment is merely illustrative, and is not intended to exclude various modifications and applications of techniques not explicitly stated in the present embodiment. Each configuration of the present embodiment can be modified in various ways without departing from the spirit of the present embodiment. Furthermore, each configuration of the present embodiment can be selected or combined as needed.

[0099] In the above embodiment, the first transition moving image 61 is exemplified, in which the first frame line 51 of the second output display unit 12 shrinks toward the center of the screen. However, it is also conceivable to apply a first transition moving image 61 in which the frame line of the first output display unit 11 shrinks toward the center of the screen, instead of the first frame line 51 of the second output display unit 12. In other words, the first frame line of the first transition moving image 61 may be any frame line having a shape corresponding to at least an area in which some output information is displayed, and is not limited to the frame line of the second output display unit 12.

[0100] FIG. 15 is a diagram showing a modified example of first display mode 4 (engine vehicle). The specific content shown on second output display unit 12 and the specific shape of the bar graph may be changed as appropriate. For example, as shown in FIG. 15, the upper limit of the displayed vehicle speed may be set to 200 km / h or more (approximately 230 km / h in FIG. 15), and the length of the bar graph may be extended in accordance with the increase in the upper limit. The shape of the extended portion (lower right portion) of the bar graph shown in FIG. 15 corresponds to the shape of the upper right portion flipped upside down. Note that a similar shape may be applied to the lower left portion of the bar graph, making the overall shape octagonal.

[0101] This display screen configuration ensures the length of the bar graph display area without compromising the visual unity or design. Furthermore, compared to when the bar graph extends vertically downward, extending the extended portion (lower right portion) of the bar graph diagonally downward and to the left can shorten the vertical dimension of the second output display unit 12. Therefore, this display screen configuration is useful when it is desired to arrange indicators below the second output display unit 12, and allows information to be displayed compactly and efficiently.

[0102] The above-described embodiments relating to the hybrid vehicle can be applied to a plug-in hybrid vehicle (PHEV) that can be externally charged or externally fed with power. A plug-in hybrid vehicle is a hybrid vehicle (HEV) that is equipped with an engine and a motor as a drive source, a generator as a power generation device, and a battery as a power storage device, and that can be externally charged or externally fed with power from the battery.

[0103] The former plug-in hybrid vehicle is equipped with a charging port (inlet) for inserting a charging cable that supplies power from an external charging facility, a wireless power receiving device, etc. The latter plug-in hybrid vehicle is equipped with an outlet for external power supply, a wireless power supply device, etc. It is possible to install both the above charging port and outlet on the same plug-in hybrid vehicle. [Industrial Applicability]

[0104] The present invention is applicable to the manufacturing industry of display devices mounted on vehicles, and also applicable to the manufacturing industry of vehicles equipped with such display devices. [Explanation of symbols]
