Description

display device

[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.

[0002] Conventionally, among display devices that display vehicle speed information and output information (engine output-related information, motor output-related information, etc.), 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 offset from the front. It has also been proposed to enable these display modes (image layouts) to be switched (see Patent Document 1).

[0003] Japanese Patent Application Laid-Open No. 2016-002808

[0004] Images that mimic existing analog meters are well-suited to conveying vehicle speed information and output information in an easy-to-understand manner, regardless of the language used by the user (of the display device). However, they have a problem in that their information density (the amount of information per unit area of ​​the screen on which the image is displayed) is relatively low, making them a disadvantage when it comes to miniaturizing the display device. To address this problem, it is conceivable to increase the information density by reducing the size of the image that mimics the analog meter itself. However, in this case, the visibility and comprehensibility of the information contained in the image may decrease, and there is a risk that the correct information may not be conveyed.

[0005] One of the objectives of the present invention, which was devised in light of the above-mentioned problems, is to provide a display device that can improve information density without impairing the clarity of information. 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" below, which are not obtainable with conventional technologies.

[0006] The disclosed display device can be realized as the following aspects or application examples, and solves at least part of the above-mentioned problems. The disclosed display device has a first display mode that has: a first content display unit that displays information representing a driving state of a vehicle or an operating state of an in-vehicle device; a first output display unit that is arranged in an area including an area above the first content display unit and represents a first output of the vehicle by the length of a bar graph drawn therein; and a second output display unit that is arranged on the periphery of the first content display unit and the first output display unit in an area including at least the left and right sides and an area above the first content display unit and the first output display unit and represents a second output of the vehicle by the length of a bar graph drawn therein.

[0007] The disclosed display device can display a wide variety of information in an easy-to-understand, compact, and efficient manner, and can improve information density without impairing the ease of understanding of the information.

[0009] [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 mounted on a vehicle and displays vehicle speed information and output information. The vehicle speed information is information that indicates the vehicle's traveling speed. This vehicle speed information is generated by various ECUs, such as a vehicle ECU (Electronic Control Unit) or a powertrain ECU. Note that the vehicle speed information can also be generated within the display device 1 based on a vehicle speed signal transmitted from a vehicle speed sensor.

[0010] 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. Note that vehicle speed information can be considered to be included in the broad definition of output information.

[0011] The display device 1 can also display other information indicating the driving state of the vehicle and the operating state of on-board devices. Specific examples of information indicating the driving state of the vehicle 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 efficiency, 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.

[0012] Furthermore, information representing 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. Hereinafter, other information representing the running status of the vehicle and the operating status of in-vehicle devices will also be referred to as content information.

[0013] 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.

[0014] 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, a projector, or the like. All information displayed on the output device 3 is controlled by the electronic control unit 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). A touch panel device that detects touch operations on a screen, an input device equipped with a keyboard, physical buttons, or a touchpad, a gaze detection device that detects gaze, a gesture reading device that detects gesture operations, or the like may be provided as ancillary devices of the output device 3.

[0015] [2. Details of Display Mode] At least two types of display modes (display modes) with different layouts are prepared as display modes (display modes) of 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.

[0016] 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.

[0017] [2-1. First Display Mode] Fig. 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 component 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 (videos).

[0018] The first output display unit 11 is a component that represents the vehicle's 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 serve as an indicator of 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 resemble the shape of the letter L rotated 90 degrees clockwise (a rotated L-shape). Alternatively, the first output display unit 11 may resemble the shape of a rectangle with the bottom and right sides removed from the four sides that make up the outline of the rectangle.

[0019] 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 indicate the length of the bar graph. The second output display unit 12 is disposed on the 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.

[0020] The first display mode 4 shown in FIG. 2 includes a first remaining capacity display unit 13 and a first numeric vehicle speed display unit 14. The first remaining capacity display unit 13 displays information indicating the remaining capacity of the battery installed in the vehicle. The first remaining capacity display unit 13 is located 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 remaining capacity may be expressed concretely using a numerical value or a percentage, or abstractly using the color or shape of an icon. In an engine vehicle not equipped with a vehicle drive battery, the remaining capacity of the auxiliary battery may be displayed on the first remaining capacity display unit 13, or the first remaining capacity display unit 13 itself may be omitted.

[0021] 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 preset 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.

[0022] 4(A) and (B) are diagrams showing specific examples of first display mode 4. Fig. 4(A) is a display example for an internal combustion 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.

[0023] 3 is a diagram showing the screen configuration of the second display mode 5. The 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 running state of the vehicle 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.

[0024] 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.

[0025] 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 preset 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.

[0026] 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.

[0027] 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.

[0028] [2-3. First Output Display Unit, First Remaining Capacity Display Unit] Figures 6(A) and 6(B) are diagrams showing specific examples of the first output display unit 11 and the first remaining capacity display unit 13. Figure 6(A) is a display example for an engine vehicle, and Figure 6(B) is a display example for a hybrid vehicle. The first output display unit 11 has a first left output area 20 and a first upper output area 21. The first left output area 20 is a section extending in the vertical direction to the left of the first content display unit 10. The first upper output area 21 is a section extending in the right direction from the upper end of the first left output area 20 above the first content display unit 10. The first left output area 20 is an area that represents a relatively lower output than the first upper output area 21.

[0029] 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.

[0030] In the display example of Fig. 6(B), the 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 the 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.

[0031] When the output value is positive (during powering), as the absolute value of the output increases, the bar graph extends from the origin to the right along the extension direction of the first output upper region 21. On the other hand, when the output value is negative (during regeneration), as the output decreases (the absolute value of the output increases), the bar graph extends from the origin to the left along the extension direction of the first output upper region 21. After the bar graph reaches the vicinity of the left end of the first output upper region 21, as the output further decreases (the absolute value of the output increases), the bar graph extends downward along the extension direction of the first output left region 20.

[0032] The first remaining capacity display unit 13 is disposed adjacent to and below the first left output area 20 (charge area). In the display examples shown in Figures 6A and 6B, an image of a dry cell battery is displayed, including a bar graph that expands in proportion to the remaining capacity. The origin of this bar graph is disposed near the bottom end of the first remaining capacity display unit 13, and the bar graph expands upward from the origin as the remaining capacity increases.

[0033] In the display example of Fig. 6(A), the extension direction of the bar graph displayed in the first remaining capacity display unit 13 matches the extension direction of the bar graph displayed in the 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 the 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 the first remaining capacity display unit 13. This makes it easier to intuitively understand that regenerative power is being charged to the drive battery.

[0034] 7(A) and 7(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 the third output display unit 16. As the output increases, the bar graph extends from the origin to the right along the extension direction of the third output display unit 16.

[0035] In the display example of Fig. 7(B), the origin of the bar graph is positioned 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 rightward from the origin as the absolute value of the output increases. On the other hand, when the output value is negative (regenerating), the bar graph extends leftward from the origin as the output decreases (the absolute value of the output increases).

[0036] The second remaining capacity display unit 18 is disposed adjacent to the left of the third output display unit 16. In the display examples 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.

[0037] In the display example of Fig. 7(A), the extension direction of the bar graph displayed in the second remaining capacity display unit 18 matches the extension direction of the bar graph displayed in the third output display unit 16. This makes it easier to intuitively understand the output of the auxiliary battery and the engine. In addition, in the display example of Fig. 7(B), the extension direction of the output during regeneration displayed in the 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 the second remaining capacity display unit 18. This makes it easier to intuitively understand that regenerative power is being charged to the drive battery.

[0038] [2-5. Second Output Display Unit] FIG. 8 is a diagram illustrating 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 portion extending vertically 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 portion 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 portion 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 vertically.

[0039] In the display example of FIG. 8 , the origin (the mark indicating a vehicle speed of 0) of the bar graph representing the vehicle speed is located near the bottom end of the second output left region 22. As the vehicle speed increases, the bar graph extends upward from the origin along the extension direction of the second output left region 22. After the bar graph reaches near the top end of the second output left region 22, if the vehicle speed increases further, the bar graph extends rightward along the extension direction of the second output upper region 23. After the bar graph reaches near the right end of the second output upper region 23, if the vehicle speed increases further, the bar graph extends downward along the extension direction of the second output right region 24.

[0040] In the display examples of Figures 6(A) and 8, the extension direction of the bar graph in the second output display unit 12 (second output left area 22) matches the extension direction of the bar graph in 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 Figures 6(B) and 8, the extension direction of the bar graph in the second output display unit 12 (second output upper area 23) matches the extension direction of the bar graph (during powering) in 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.

[0041] [2-6. First Numeric Vehicle Speed ​​Display Unit, Second Numeric Vehicle Speed ​​Display Unit] Fig. 9(A) is a diagram showing a specific example of the first numeric vehicle speed display unit 14, and Fig. 9(B) is a diagram showing a specific example of the second numeric vehicle speed display unit 17. The first numeric vehicle speed display unit 14 has a numeric display area 25 that displays at least the vehicle speed in numbers. In addition, the 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 the cruise control display area 26, the regulations display area 27, and the conversion value display area 28 may be preset depending on the destination of the vehicle, or may be selectable by the user.

[0042] The 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 driver operation, and includes, for example, constant speed control on expressways, automatic following control for a preceding vehicle, and control for maintaining a safe distance between vehicles. Specifically, telltales (icons, marks) indicating that cruise control is being performed, telltales indicating the set vehicle speed during constant speed control, and telltales indicating that a preceding vehicle that should be followed is present and a predetermined safe distance is maintained are displayed. The legal regulations display area 27 is an area that displays information related to vehicle speeds that comply with legal regulations. The legal regulations display area 27 displays, for example, the legal maximum speed and the designated speed for each section of the road currently being traveled.

[0043] 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. The user may be able to select the unit to be converted here.

[0044] 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.

[0045] [2-7. First Content Display Unit] Fig. 10(A) is a diagram showing the screen configuration of the first content display unit 10, and Figs. 10(B) to (E) are diagrams showing specific examples of the first content display unit 10. The first content display unit 10 has a first title display area 30 in which the title of the information is displayed, a first content display area 31 in which 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.

[0046] 10(B) to 10(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.

[0047] 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 example display shown in Figure 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 aspect) and an item for selecting whether to turn the display of the first numeric vehicle speed display unit 14 on or off.

[0048] 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."

[0049] 11(A) is a diagram showing the screen configuration of the second content display unit 15, and FIGS. 11(B) to 11(E) are diagrams showing specific examples of the second content display unit 15. The second content display unit 15 has an area that is 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 cover the area where the first output display unit 11 and the second output display unit 12 were located.

[0050] 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.

[0051] Regarding the relationship between the first content display unit 10 and the second content display unit 15, the second title display area 34 is disposed above the first title display area 30, and the second boundary line 36 is disposed above the first boundary line 32. The second content display area 35 is formed to be larger in size than the first content display area 31, and is formed, for example, in a shape that expands the first content display area 31 upward, leftward, and rightward.

[0052] 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).

[0053] 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, the drive battery, the drive motor, and the drive wheels mounted on the vehicle are shown in perspective views, and the movement of energy (driving force or electric power) is represented by arrows.

[0054] 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 in size and show the layout of each display mode are displayed.

[0055] 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 as seen from above behind the vehicle. The viewpoint in the second perspective view is preferably set higher than the viewpoint in the first perspective view. This improves the readability of the second perspective view and provides a better view of a wider area.

[0056] 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, the second boundary line 36 and the second horizon 39 do not change even if the information displayed on the second content display unit 15 is switched. Note that the second boundary line 36 and the second horizon 39 do not have to have exactly the same shape.

[0057] [3. Effects] (1) The display device 1 of this embodiment has a first display mode 4 having 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 displays information indicating the driving state of the vehicle or the operating state of on-board equipment. The first output display unit 11 is arranged in an area including the upper part of the first content display unit 10, and the length of a bar graph drawn therein indicates the output of the vehicle. The second output display unit 12 is arranged on the outer periphery of the first content display unit 10 and the first output display unit 11, in an area including at least the left and right sides and the upper part of the first content display unit 10 and the first output display unit 11, and the length of a bar graph drawn therein indicates the vehicle speed.

[0058] This configuration allows a wide variety of information to be displayed clearly, compactly, and efficiently, improving information density without compromising the clarity of the information. For example, as shown in Figures 4(A) and 4(B), the second output display unit 12 can be placed on the outermost side of a rectangular display area, with the first content display unit 10 and the first output display unit 11 comfortably placed inside. This makes it easy to realize a display device 1 that is easy for users to see and understand the displayed content, and is highly convenient.

[0059] (2) The first output display unit 11 may be provided with a first left output area 20 and a first upper output area 21. The first left output area 20 extends in the vertical direction to the left of the first content display unit 10. The first upper output area 21 extends in the right direction from the upper end of the first left output area 20 above the first content display unit 10. Furthermore, the second output display unit 12 may be provided with a second left output area 22, a second upper output area 23, and a second right output area 24.

[0060] The second left output area 22 extends vertically to the left of the first left output area 20. The second upper output area 23 extends rightward from the upper end of the second left output area 22 above the first upper output area 21. The second right output area 24 extends downward from the right end of the second upper output area 23 to the right of the first content display unit 10. With this configuration, the first left output area 20 and the second left output area 22 can be displayed side by side, improving information density without compromising the clarity of the information. This also further improves the convenience of the display device 1.

[0061] (3) The first display mode 4 may be provided with a first remaining capacity display unit 13. The first remaining capacity display unit 13 is disposed adjacent to and below the first output display unit 11 (first output left area 20) and displays information indicating the remaining capacity of the battery installed in the vehicle. By locating the first remaining capacity display unit 13 adjacent to and below the first output display unit 11 (first output left area 20) in this manner, the information density can be improved without compromising the readability of the information. Furthermore, the convenience of the display device 1 can be further improved.

[0062] (4) In a hybrid vehicle equipped with a motor that performs power running and regenerative power generation, a power area that indicates the power consumption of the motor and a charge area that indicates the charging power of the drive battery may be provided in the first output display unit 11. In this case, as shown in FIG. 6(B), the charge area may be located in at least the first left output area 20, and the first remaining capacity display unit 13 may be located adjacent to and below the charge area.

[0063] This configuration makes it possible to clearly see the relationship between the state of regenerative power generation by the motor and the resulting remaining capacity of the drive battery, and presents information in an easy-to-understand manner. Furthermore, in the display example of FIG. 6(B), the direction of increase in the output during regeneration (the direction in which the negative output value increases) displayed within the first output display unit 11 is opposite to the direction of increase in the bar graph displayed within the first remaining capacity display unit 13. This makes it easy to intuitively understand that regenerative power is being charged to the drive battery. Furthermore, the convenience of the display device 1 can be further improved.

[0064] (5) In the first display mode 4, a first numeric vehicle speed display unit 14 may be provided that indicates the vehicle speed in numbers, separate from the second output display unit 12. In this way, by displaying not only a bar graph but also the vehicle speed in numbers, the efficiency of information transmission can be improved. In addition, the convenience of the display device 1 can be further improved. Note that the numeric display is convenient when you want to instantly grasp the vehicle speed, because it does not require you to visually estimate the length of the bar graph using a scale or pointer, as is the case with a bar graph display.

[0065] (6) The first numeric vehicle speed display unit 14 may have additional areas for displaying information other than the numeric display area 25, such as a cruise control display area 26, a regulations display area 27, and a conversion value display area 28. The cruise control display area 26 is an area for displaying information related to cruise control, which automatically increases or decreases the vehicle speed without the driver's input. The regulations display area 27 is an area for displaying information related to the vehicle speed in accordance with the regulations, and the conversion value display area 28 is an area for displaying the vehicle speed converted into another unit.

[0066] By providing the above-described areas, information can be presented in an easily understandable manner in a limited space, improving information density. Furthermore, the convenience of the display device 1 can be further improved. The regulations display area 27 and the conversion value display area 28 may be added only when such display functions are required in the destination of the vehicle. Furthermore, the cruise control display area 26 is unnecessary for vehicles without a cruise control function. Note that the speed units commonly used in the destination and the speed units that are easy for users to understand do not necessarily coincide. Therefore, from the viewpoint of usability, the conversion value display area 28 may be provided as standard equipment on the first numeric vehicle speed display unit 14 regardless of the destination.

[0067] (7) The first content display unit 10 may be provided with a first title display area 30 displaying the title of the information, a first content display area 31 displaying the content of the information, and a first boundary line 32 extending horizontally and vertically separating the first title display area 30 from the first content display area 31. With this configuration, a user can quickly grasp the meaning and subject of the information displayed in the first content display area 31 simply by viewing the first title display area 30. Therefore, the information density can be improved without compromising the understandability of the information. Furthermore, by drawing the first boundary line 32 between the first title display area 30 and the first content display area 31, each piece of information can be clearly separated and presented within a limited space. Furthermore, the convenience of the display device 1 can be further improved.

[0068] (8) As shown in FIG. 10(E), the first content display unit 10 may have a function for displaying the positional relationship between the vehicle and surrounding vehicles or obstacles using a first perspective view that simulates a view of the vehicle as seen from above and behind the vehicle. In this case, it is preferable that the first horizon 33 between the ground and the sky in the first perspective view is displayed at the same position as the first boundary line 32. By aligning the first horizon 33 and the first boundary line 32 on the screen in this way, even when the display content of the first content display unit 10 is switched, a sense of unity can be imparted to the display content, allowing a wide variety of information to be displayed in an easy-to-understand manner without causing the user to feel uncomfortable. This also further improves the convenience of the display device 1.

[0069] (9) The display device 1 may also have a second display mode 5 including 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 has a larger area than the first content display unit 10 and displays information indicating the vehicle's running state or the operating state of on-board equipment. The third output display unit 16 is disposed below the second content display unit 15 and represents the vehicle's output by the length of a bar graph drawn therein. The second numeric vehicle speed display unit 17 is disposed above the second content display unit 15 and represents the vehicle's speed in numbers. Preferably, the first display mode 4 and the second display mode 5 are switchable.

[0070] With this configuration, information indicating the vehicle's running state or the operating state of on-board equipment can be displayed in a larger area than in first display mode 4. For example, as shown in Figures 5(A) and 5(B), a large amount of information can be displayed inside the large second content display section 15, or information can be displayed using enlarged images or characters. Therefore, it is possible to easily realize a display device 1 that is easy for the user to see and understand the displayed content, and is highly convenient.

[0071] (10) The second display mode 5 may be provided with a second remaining capacity display unit 18. The second remaining capacity display unit 18 is disposed adjacent to the left of the third output display unit 16 and displays information indicating the remaining capacity of the battery installed in the vehicle. By locating the second remaining capacity display unit 18 adjacent to the left of the third output display unit 16 in this manner, the information density can be improved without impairing the readability of the information. Furthermore, the convenience of the display device 1 can be further improved.

[0072] (11) The second numeric vehicle speed display unit 17 may be provided with a cruise control display area 26, a regulations display area 27, a conversion value display area 28, etc., similar to the first numeric vehicle speed display unit 14. By providing these areas, information can be presented in an easy-to-understand manner in a limited space, improving information density. Furthermore, by aligning the content displayed on the first numeric vehicle speed display unit 14 with the content displayed on the second numeric vehicle speed display unit 17, the display content can be maintained before and after switching between the first display mode 4 and the second display mode 5, improving convenience.

[0073] (12) The second content display unit 15 may be provided with a second title display area 34 in which the title of the information is displayed, a second content display area 35 in which the content of the information is displayed, and a second boundary line 36 extending horizontally to vertically separate the second title display area 34 from the second content display area 35. In this case, the second boundary line 36 is preferably positioned above the first boundary line 32.

[0074] With the above configuration, the meaning and subject of the information displayed in the second content display area 35 can be quickly grasped simply by viewing the second title display area 34. Therefore, the information density can be improved without compromising the clarity of the information. Furthermore, by drawing the second boundary line 36 between the second title display area 34 and the second content display area 35, each piece of information can be clearly separated and presented within a limited space. Furthermore, by positioning the second boundary line 36 above the first boundary line 32, the display area of ​​the second content display area 35 can be expanded, thereby easily improving the readability of information and easily increasing the amount of information. Furthermore, the convenience of the display device 1 can be further improved.

[0075] (13) As shown in FIG. 11(E), the second content display unit 15 may have a function for displaying the positional relationship between the vehicle and surrounding vehicles or obstacles using a second perspective view simulating a view of the vehicle as seen from above and behind the vehicle. In this case, it is preferable that the second horizon 39 between the ground and the sky in the second perspective view is displayed at the same position as the second boundary line 36. By aligning the second horizon 39 and the second boundary line 36 on the screen in this way, even when the display content of the second content display unit 15 is switched, a sense of unity can be imparted to the display content, allowing a wide variety of information to be displayed in an easy-to-understand manner without causing the user to feel uncomfortable. This also further improves the convenience of the display device 1.

[0076] (14) The second content display unit 15 may display substantially the same information as the information displayed in the first content display unit 10, as shown in, for example, Figures 10(B) and 11(B). Alternatively, as shown in Figures 10(C) and 11(C), the second content display unit 15 may display a detailed image 37 illustrating details of the information displayed in the first content display unit 10. Alternatively, as shown in Figures 10(D) and 11(D), the second content display unit 15 may display a detailed image 38 for supplemental explanation illustrating details of the information displayed in the first content display unit 10. By additionally displaying the detailed images 37 and 38 in this way, information can be presented in an easily understandable manner, thereby improving convenience.

[0077] [4. Other] The above-described embodiments are merely illustrative and are not intended to exclude various modifications or applications of techniques not explicitly stated in the present embodiments. Each configuration of the present embodiments can be modified in various ways without departing from the spirit of the present embodiments. Furthermore, each configuration of the present embodiments can be selected or combined as needed. For example, while the display device 1 described above has a first display mode 4 and a second display mode 5, the second display mode 5 can be omitted. Furthermore, the display elements in the first display mode 4 and the second display mode 5 can be changed as needed.

[0078] FIG. 12 is a diagram illustrating an example of the minimum configuration of a screen in first display mode 4. First display mode 4 may include at least a first content display unit 10, a first output display unit 11, and a second output display unit 12. The first output display unit 11 may be disposed in a range including the area above the first content display unit 10. The second output display unit 12 may be disposed around the periphery of the first content display unit 10 and the first output display unit 11, in a range including at least the left and right sides and the area above the first content display unit 10 and the first output display unit 11. This configuration allows a wide variety of information to be presented in an easy-to-understand, compact, and efficient manner, improving information density without compromising the understandability of the information. Furthermore, the convenience of the display device 1 may be improved.

[0079] FIG. 13 is a diagram illustrating an example of the minimum configuration of the screen of second display mode 5 when second display mode 5 is provided. Second display mode 5 may include at least second content display unit 15, third output display unit 16, and second numeric vehicle speed display unit 17. Furthermore, third output display unit 16 may be disposed below second content display unit 15, and second numeric vehicle speed display unit 17 may be disposed above second content display unit 15. This configuration allows a wide variety of information to be presented in an easy-to-understand, compact, and efficient manner, improving information density without compromising the understandability of the information. Furthermore, the convenience of the display device 1 can be further improved.

[0080] Specific parameters of the first output and the third output displayed on the first output display unit 11 and the third output display unit 16, and the second output displayed on the second output display unit 12, can be set arbitrarily. Various combinations of specific output information to be displayed on each of the first output display unit 11, the second output display unit 12, and the third output display unit 16 are conceivable.

[0081] FIG. 14 shows a modified example of first display mode 4 (engine vehicle). The specific content and the specific shape of the bar graph displayed on the second output display unit 12 may be changed as appropriate. For example, as shown in FIG. 14 , the upper limit of the displayed vehicle speed may be set to 200 km / h or higher (approximately 230 km / h in FIG. 14 ), and the length of the bar graph may be extended as the upper limit increases. The shape of the extended portion (lower right portion) of the bar graph shown in FIG. 14 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.

[0082] 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 reduces 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.

[0083] The above-described embodiment of 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.

[0084] 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 external power supply outlet (outlet), a wireless power supply device, etc. It is possible to install both the above charging port and outlet in a single plug-in hybrid vehicle.

[0085] Furthermore, the layout of the first output display unit 11 and the second output display unit 12 may be flipped left and right relative to the display area of ​​the output device 3. For example, the overall shape of the first output display unit 11 shown in FIGS. 4A and 4B has the shape of the letter L rotated 90 degrees clockwise (a rotated L-shape), but the overall shape of the first output display unit 11 may be a mirror image of this shape. In this case, the bar graph drawn inside the first output display unit 11 may or may not be flipped left and right in the same way. For example, the origin (the scale indicating that the output is 0) of the bar graph representing the output level may be set to the lower right part of the first output display unit 11 or to the left end of the first output display unit 11. Note that what is flipped left and right here is the overall shape of the first output display unit 11 and the bar graph, and the numerical values ​​and characters representing the output magnitude do not need to be flipped left and right.

[0086] 8, the origin of the bar graph representing the vehicle speed (the scale mark representing a vehicle speed of 0) is located near the bottom end of the second output left area 22, but the origin may be located near the bottom end of the second output right area 24. In other words, the change in vehicle speed may be represented by the bar graph extending counterclockwise as the vehicle speed increases. In this way, the specific content and the specific shape of the bar graph shown on the first output display unit 11 and the second output display unit 12 may be changed as appropriate.

[0087] 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.
