Description

Technical Field

[0001] The present invention relates to a display device mounted on a vehicle and displaying vehicle speed information, output information, etc. Background Art

[0002] Conventionally, in a display device that displays vehicle speed information, output information (engine output-related information, motor output-related information, etc.), there is known a device that displays an image imitating an existing analog instrument. For example, there is known a device that displays an image corresponding to a state of observing an analog instrument from the front, or a device that displays an image corresponding to a state of observing an analog instrument obliquely from a position deviated from the front. In addition, a scheme for switching these display modes (layouts of images) has been proposed (see Patent Document 1).

[0006] Technical Problem to be Solved by the Invention

[0007] An image imitating an existing analog instrument is independent of the language used by a user (a person who uses the display device), and is suitable for easily communicating vehicle speed information and output information. On the other hand, there is a technical problem that the information density (the amount of information per unit area of the display image screen) is relatively low, which is disadvantageous for miniaturizing the display device. For such a technical problem, it is also possible to consider improving the information density by reducing the size of the image imitating the analog instrument itself. However, in this case, the visual confirmability and understandability of the information contained in the image are reduced, and there is a concern that correct information cannot be transmitted. Summary of the Invention

[0008] One object of the present invention is to provide a display device that is created in view of the above technical problem and can improve the information density without impairing the understandability of information. In addition, not limited to this object, effects that are derived from each structure shown in the following "Detailed Description" and cannot be obtained by the prior art are also regarded as other objects of the present invention.

[0009] Technical Means for Solving the Technical Problem

[0010] The disclosed display device can be implemented as the following disclosed modes or application examples, and solves at least a part of the above technical problems.

[0011] The disclosed display device has a first display mode, which has: a first content display unit that displays information indicating the driving state of a vehicle or the operating state of in-vehicle equipment; a first output display unit that is arranged in a range above the first content display unit and represents the first output of the vehicle by the length of a bar graph drawn inside the first output display unit; and a second output display unit that is arranged on the outer periphery of the first content display unit and the first output display unit, in a range including at least the left and right sides and above the first content display unit and the first output display unit, and represents the second output of the vehicle by the length of a bar graph drawn inside the second output display unit.

[0012] Effect of the Invention

[0028] [1. Structure]

[0029] Figure 1 It is a block diagram showing the structure of the display device 1 as an embodiment. The display device 1 is a device mounted on a vehicle and displays vehicle speed information and output information. The vehicle speed information is information indicating the traveling speed of the vehicle. The vehicle speed information is generated by various ECUs such as a vehicle ECU (Electronic Control Unit) and a powertrain ECU, for example. In addition, the vehicle speed information can also be generated inside the display device 1 based on the vehicle speed signal transmitted from the vehicle speed sensor.

[0030] The output information is information about the output (power) of the vehicle's drive source. As specific examples of the output information, information such as the engine speed, engine torque, engine horsepower (power), the speed of the driving motor, the torque of the driving motor, the horsepower (power) of the driving motor, the power consumption of the driving motor, and the power supplied by the drive battery can be cited. The output information is generated by various ECUs, for example, and transmitted to the display device 1. In addition, the vehicle speed information can be regarded as being included in the broad sense of the output information.

[0031] In addition, the display device 1 can display other information indicating the driving state of the vehicle and the operating state of in-vehicle devices. As specific examples of the information indicating the driving state of the vehicle, information such as 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 consumption, the power 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 power train, the driving direction (azimuth), the altitude, the temperature, and the road surface friction coefficient can be cited.

[0032] In addition, the information indicating the operating state of in-vehicle devices can include audio information, vehicle navigation information, lighting state information, cruise control related information, inter-vehicle distance information, various websites, and the like. These information are generated or acquired by various ECUs, various in-vehicle devices, various sensors, etc., for example, and transmitted to the display device 1. Hereinafter, the other information indicating the driving state of the vehicle and the operating state of in-vehicle devices is also referred to as content information.

[0033] As Figure 1 shown, 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 has a built-in processor (arithmetic processing device) and a memory (storage device). The processing content (program) of the electronic control device 2 is stored in the memory and is executed by appropriately reading its content into the processor. In addition, the electronic control device 2 can be integrally formed with the output device 3 (built into the output device 3) or can be provided separately from the output device 3.

[0034] The output device 3 is a device that displays information related to the vehicle, such as a liquid crystal display, an organic EL (Electro-Luminescence) display, a projector, etc. All the information displayed on the output device 3 is controlled by the electronic control device 2. The shape of the display area of the information in the output device 3 is not particularly limited, for example, it is a rectangular shape. The output device 3 is arranged at a position in front of the driver (in front of the steering wheel), in front of the center of the vehicle compartment (in front of the middle of the driver's seat and the passenger seat), etc., where the driver can easily see. As an accessory device of the output device 3, it is also possible to provide: a touch panel device that detects touch operations on the screen; an input device provided with a keyboard, physical buttons, a touchpad; a gaze detection device that detects the line of sight; a gesture reading device that detects gesture operations, etc.

[0035] [Details of the display mode]

[0036] As the display mode (display method) of the information displayed on the output device 3, at least two modes with different layouts are prepared. One of these modes is called the first display mode 4, and the other mode is called the second display mode 5. These modes can be arbitrarily selected by the user.

[0037] The first display mode 4 is a mode that provides the appearance of a standard instrument display, and is a mode that displays vehicle speed information, output information, and content information. In addition, the second display mode 5 is a mode in which the display of content information is enhanced. In the second display mode 5, compared with the first display mode 4, the display area of the content information is enlarged, and the display area of the vehicle speed information is reduced.

[0038] [2-1. First display mode]

[0039] Figure 2 It is a diagram showing the screen composition of the first display mode 4. The first display mode 4 has at least a first content display section 10, a first output display section 11, and a second output display section 12. The first content display section 10 is a part that displays information (content information) indicating the driving state of the vehicle or the operating state of in-vehicle equipment. In the first content display section 10, information such as characters, numbers, pictograms, images, and videos (animations) can be displayed, for example.

[0040] The first output display section 11 is a part that represents the output (first output) of the vehicle by the length of a bar graph drawn inside it. Hereinafter, the description of "output" can also be understood by using another expression as "first output". At least a bar graph indicating the height of the output is displayed in the first output display section 11, and preferably, a scale, a pointer, a numerical value, a unit, etc., which are indicators of its length, are displayed. The first output display section 11 is arranged in a range that at least includes above the first content display section 10. Figure 2The first output display unit 11 shown is disposed to the left and above the first content display unit 10. The overall shape of the first output display unit 11 can be based on a shape obtained by rotating the letter L clockwise by 90 degrees (a rotated L shape). Alternatively, it can be based on a shape obtained by removing the lower side and the right side among the four sides forming the quadrilateral outline.

[0041] The second output display unit 12 is a part that represents the vehicle speed, which is the second output of the vehicle, by the length of a bar graph drawn inside it. Hereinafter, the description of "vehicle speed" can also be understood as being recorded in another expression as "second output". In addition, the second output includes not only the vehicle speed but also other outputs (for example, the first output). At least a bar graph representing the height of the vehicle speed is displayed on the second output display unit 12, and preferably, a scale, a pointer, a numerical value, a unit, etc., which are indicators of its length, are displayed. In addition, the second output display unit 12 is disposed in a range including at least the left and right sides and above of the first content display unit 10 and the first output display unit 11 on the outer periphery of the first content display unit 10 and the first output display unit 11. As Figure 2 shown, the overall shape of the second output display unit 12 can be based on a shape obtained by inverting the letter U upside down (an inverted U shape). Alternatively, it can be based on a shape obtained by removing only the lower side among the four sides forming the quadrilateral.

[0042] Figure 2 The first display mode 4 shown has a first remaining capacity display unit 13 and a first digital vehicle speed display unit 14. The first remaining capacity display unit 13 is a part that displays information representing the remaining capacity of the battery mounted on the vehicle. The first remaining capacity display unit 13 is disposed adjacent to the left of the first content display unit 10 and below the first output display unit 11. In a hybrid vehicle equipped with a driving motor and an engine with a generator, the remaining capacity of the driving battery (high-voltage battery) is displayed on the first remaining capacity display unit 13. The size of the remaining capacity can be specifically represented by a numerical value or a percentage, or can be abstractly represented by the color or shape of an icon. In addition, in an engine vehicle not equipped with a vehicle driving battery, the remaining capacity of the auxiliary equipment battery can be displayed on the first remaining capacity display unit 13, or the display of the first remaining capacity display unit 13 itself can be omitted.

[0043] The first digital vehicle speed display unit 14 is a part that separately displays the vehicle speed of the vehicle in digits from the second output display unit 12. The unit of the vehicle speed displayed here can be preset according to the destination of the vehicle, or can be arbitrarily set by the user. Specific examples of the unit of the vehicle speed can include km / h (kilometer per hour), mph (mile per hour), m / s (meter per second), etc. In addition, the user can arbitrarily select the on / off of the display of the first digital vehicle speed display unit 14.

[0044] Figure 4 Figs. (A) and (B) are diagrams showing specific examples of the first display mode 4. Figure 4 Fig. (A) is a display example in an engine vehicle, Figure 4 and Fig. (B) is a display example in a hybrid vehicle equipped with an electric motor for power running and regenerative power generation. In either display example, a first content display section 10, a first output display section 11, a second output display section 12, a first remaining capacity display section 13, and a first digital vehicle speed display section 14 are included. In addition, in parts other than these, in addition to the display time, outside air temperature, name of the driving mode, shift position, driving distance, etc., the type of information to be displayed in the first content display section 10 and icons for display settings are also displayed.

[0045] [2-2. Second Display Mode]

[0046] Figure 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 section 15, a third output display section 16, and a second digital vehicle speed display section 17. The second content display section 15 is a part for displaying information indicating the driving state of the vehicle or the operating state of in-vehicle equipment, and has a wider range than the first content display section 10. In the second content display section 15, information that is the same (or substantially the same) as the information displayed in the first content display section 10 can be displayed, or a detailed image illustrating the details of the information can be displayed.

[0047] The third output display section 16 is a part that represents the output of the vehicle by the length of a bar graph drawn inside it, like the first output display section 11. In the third output display section 16, at least a bar graph indicating the height of the output is displayed, and preferably, a scale, pointer, numerical value, unit, etc. as an index of its length are displayed. The third output display section 16 is arranged within a range including at least below the second content display section 15. Figure 3 The third output display section 16 shown is arranged substantially horizontally along the lower edge of the second content display section 15.

[0048] The second digital vehicle speed display section 17 is a part that represents the vehicle speed numerically, like the first digital vehicle speed display section 14. The unit of the vehicle speed displayed here can be preset according to the destination of the vehicle or can be arbitrarily set by the user. In the second display mode 5, the second digital vehicle speed display section 17 is always displayed, and the user cannot select the on / off of the display of the second digital vehicle speed display section 17.

[0049] Figure 3The second display mode 5 shown has a second remaining capacity display section 18. The second remaining capacity display section 18, like the first remaining capacity display section 13, is a part that displays information indicating the remaining capacity of the battery mounted on the vehicle. The second remaining capacity display section 18 is disposed adjacent to the left of the third output display section 16 below the second content display section 15. In a hybrid vehicle, the remaining capacity of the drive battery is displayed on the second remaining capacity display section 18. In an engine vehicle, the remaining capacity of the auxiliary equipment battery can be displayed on the second remaining capacity display section 18, or the display of the second remaining capacity display section 18 itself can be omitted.

[0050] Figure 5 (A) and (B) of FIG. are diagrams showing specific examples of the second display mode 5. Figure 5 (A) of FIG. is a display example in an engine vehicle, Figure 5 (B) of FIG. is a display example in a hybrid vehicle. In either display example, a second content display section 15, a third output display section 16, a second digital vehicle speed display section 17, and a second remaining capacity display section 18 are included. In addition, at positions other than these, in addition to displaying the time, outside air temperature, name of the driving mode, shift position, driving distance, etc., icons for selecting the type of information to be displayed on the second content display section 15 and display settings are also displayed.

[0051] [2-3. First Output Display Section, First Remaining Capacity Display Section]

[0052] Figure 6 (A) and (B) of FIG. are diagrams showing specific examples of the first output display section 11 and the first remaining capacity display section 13. Figure 6 (A) of FIG. is a display example in an engine vehicle, Figure 6 (B) of FIG. is a display example in a hybrid vehicle.

[0053] The first output display section 11 has a first output left region 20 and a first output upper region 21. The first output left region 20 is a part that extends in the vertical direction to the left of the first content display section 10. In addition, the first output upper region 21 is a part that extends in the right direction from the upper end of the first output left region 20 above the first content display section 10. The first output left region 20 is a region indicating a relatively lower output compared to the first output upper region 21.

[0054] In Figure 6In the display example of (A), the position of the origin of the bar graph indicating the output height (the scale indicating an output of 0) is arranged near the lower end of the first output left region 20. As the output increases, the bar graph extends upward from the origin along the extension direction of the first output left region 20. After the bar graph reaches near the upper end of the first output left region 20, if the output further increases, it extends rightward along the extension direction of the first output upper region 21.

[0055] In Figure 6 the display example of (B), the first output display unit 11 has a power region and a charging region. In addition, in Figure 6 the display example of (B), the position of the origin of the bar graph forming the boundary between the power region and the charging region is arranged near the middle part between the left end and the center of the first output upper region 21. The power region is a region indicating the power consumption of the motor, and the charging region is a region indicating the charging power of the drive battery.

[0056] When the output value is positive (during power operation), the bar graph extends rightward from the origin 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), as the output decreases (the absolute value of the output increases), it extends leftward from the origin along the extension direction of the first output upper region 21. After the bar graph reaches near 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.

[0057] The first remaining capacity display unit 13 is arranged adjacent to the lower side of the first output left region 20 (charging region). In Figure 6 the display examples of (A) and (B), an image in the shape of a dry battery including a bar graph that extends in proportion to the remaining capacity is displayed. The origin of this bar graph is arranged near the lower end of the first remaining capacity display unit 13, and the bar graph extends upward from the origin as the remaining capacity increases.

[0058] In Figure 6 the display example of (A), the extension direction of the bar graph displayed inside the first remaining capacity display unit 13 is the same as the extension direction of the bar graph displayed inside the first output left region 20. Thus, it is easy to intuitively understand the output of the auxiliary equipment battery and the engine. In addition, in Figure 6 the display example of (B), the extension direction of the output during regeneration (the direction in which the negative output value increases) displayed inside the first output display unit 11 becomes the opposite direction to the extension direction of the bar graph displayed inside the first remaining capacity display unit 13. Thus, it is easy to intuitively understand the situation where the regenerative power is charged to the drive battery.

[0059] [2-4. Third Output Display Section, Second Remaining Capacity Display Section]

[0060] Figure 7 In (A) and (B) thereof, there are diagrams showing specific examples of the third output display section 16 and the second remaining capacity display section 18. Figure 7 (A) thereof is an example of display in an engine vehicle, Figure 7 (B) thereof is an example of display in a hybrid vehicle.

[0061] In Figure 7 the display example of (A) thereof, the position of the origin of the bar graph is arranged near the left end portion of the third output display section 16. As the output becomes higher, the bar graph extends rightward from the origin along the extending direction of the third output display section 16.

[0062] In Figure 7 the display example of (B) thereof, the position of the origin of the bar graph is arranged near the middle portion between the left end and the center of the third output display section 16. When the output value is positive (during power running), 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 (during regeneration), as the output becomes smaller (the absolute value of the output increases), it extends leftward from the origin.

[0063] The second remaining capacity display section 18 is arranged adjacent to the left of the third output display section 16. In Figure 7 the display examples of (A) and (B) thereof, an image in the shape of a dry cell including a bar graph that extends in proportion to the remaining capacity is displayed. The origin of this bar graph is arranged near the left end portion of the second remaining capacity display section 18, and the bar graph extends rightward from the origin as the remaining capacity increases.

[0064] In Figure 7 the display example of (A) thereof, the extending direction of the bar graph displayed inside the second remaining capacity display section 18 is the same as the extending direction of the bar graph displayed inside the third output display section 16. Thus, it is easy to intuitively understand the output of the auxiliary battery and the engine. Additionally, in Figure 7 the display example of (B) thereof, the extending direction of the output during regeneration (the direction in which the negative output value increases) displayed inside the third output display section 16 becomes the opposite direction to the extending direction of the bar graph displayed inside the second remaining capacity display section 18. Thus, it is easy to intuitively understand the situation where the regenerative power is charged to the driving battery.

[0065] [2-5. Second Output Display Section]

[0066] Figure 8It 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 region 22, a second output upper region 23, and a second output right region 24. The second output left region 22 is a part that extends vertically to the left of the first output display unit 11 (for example, the first output left region 20). The second output upper region 23 is a part that extends horizontally to the right from the upper end of the second output left region 22 above the first output display unit 11 (for example, the first output upper region 21). The second output right region 24 is a part that extends downward from the right end of the second output upper region 23 to the right of the first output display unit 11 and the first content display unit 10. The second output left region 22 is a region indicating a relatively low vehicle speed compared to the second output upper region 23 and the second output right region 24. The height positions of the lower ends of the second output left region 22 and the second output right region 24 are the same.

[0067] In Figure 8 In the display example, the position of the origin (the scale indicating a vehicle speed of 0) of the bar graph representing the height of the vehicle speed is arranged near the lower 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. When the bar graph reaches near the upper end of the second output left region 22 and the vehicle speed further increases, the bar graph extends horizontally to the right along the extension direction of the second output upper region 23. When the bar graph reaches near the right end of the second output upper region 23 and the vehicle speed further increases, the bar graph extends downward along the extension direction of the second output right region 24.

[0068] In Figure 6 In the (A) of Figure 8 In the display example, the extension direction of the bar graph inside the second output display unit 12 (the second output left region 22) is the same as the extension direction of the bar graph inside the first output display unit 11 (the first output left region 20). Thus, it is easy to intuitively understand the state of the vehicle speed and the engine output. Similarly, in Figure 6 In the (B) of Figure 8 In the display example, the extension direction of the bar graph inside the second output display unit 12 (the second output upper region 23) is the same as the extension direction of the bar graph (during power operation) inside the first output display unit 11 (the first output upper region 21). Thus, it is easy to intuitively understand the state of the vehicle speed and the motor output.

[0069] [2-6. First digital vehicle speed display unit, second digital vehicle speed display unit]

[0070] Figure 9 (A) of Figure 9(B) is a diagram showing a specific example of the second digital vehicle speed display unit 17. The first digital vehicle speed display unit 14 has a numerical display area 25 that displays at least the numerical value of the vehicle speed in digits. In addition, Figure 9 As shown in (A) of, the first digital vehicle speed display unit 14 also has a cruise control display area 26, a regulation display area 27, and a conversion value display area 28. For each of the displays in the cruise control display area 26, the regulation display area 27, and the conversion value display area 28, the on / off state can be preset according to the destination of the vehicle or can be arbitrarily selected by the user.

[0071] 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 the vehicle speed regardless of the driving operation, and includes, for example, constant speed driving control on highways, automatic following control of a preceding vehicle, and inter-vehicle distance maintenance control. Specifically, an indication signal (icon, mark) indicating that cruise control has been implemented, an indication signal indicating the set vehicle speed during constant speed driving control, an indication signal indicating that there is a preceding vehicle to be followed and a specified inter-vehicle distance has been ensured, etc. are displayed.

[0072] The regulation display area 27 is an area that displays information related to the vehicle speed based on regulations. For example, the legally specified maximum speed, the specified speed for each section designated on the road being traveled, etc. are displayed in the regulation display area 27.

[0073] The conversion value display area 28 is an area that displays a value obtained by converting the vehicle speed displayed in the second output display unit 12 and the numerical display area 25 into other units. For example, when the unit of the vehicle speed displayed in the second output display unit 12 and the numerical display area 25 is km / h (kilometers per hour), a value converted into a different unit (mph (miles per hour), m / s (meters per second), etc.) is displayed in the conversion value display area 28. In addition, the unit for this conversion can also be arbitrarily selected by the user.

[0074] Figure 9 The second digital vehicle speed display unit 17 shown in (B) has a numerical display area 25, a cruise control display area 26, a regulation display area 27, and a conversion value display area 28. The content displayed in each of these areas is the same as the content displayed in the first digital vehicle speed display unit 14, and only the display layout is different. Thus, when the display mode is switched between the first display mode 4 and the second display mode 5, the display content of the first digital vehicle speed display unit 14 and the second digital vehicle speed display unit 17 is not impaired.

[0075] [2-7. First content display unit]

[0076] Figure 10The (A) is a diagram showing the screen configuration of the first content display section 10. Figure 10 The (B) to (E) are diagrams showing specific examples of the first content display section 10.

[0077] The first content display section 10 includes a first title display area 30 for displaying the title of the information, a first content display area 31 for displaying the content of the information, and a first boundary line 32 that divides them. The first boundary line 32 is a line that extends in the horizontal direction and divides 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.

[0078] As a specific example of the title displayed in the first title display area 30, for example, as Figure 10 shown in the (B) to (D), examples include "Drive Computer", "Energy Flow", "Settings", etc. As the content corresponding to the title "Drive Computer", in addition to Figure 10 the information on average fuel consumption and average vehicle speed shown in the (B), other examples include instantaneous fuel consumption, power consumption, driving time, estimated remaining driving distance, etc.

[0079] The title "Energy Flow" is the title of a diagram showing the state of energy movement between the engine with a generator, the drive battery, and the drive wheels. In Figure 10 the display example shown in the (C), each of the engine with a generator, the drive battery, and the drive wheels is represented by a simple icon, and the state of energy (driving force or electric power) movement is represented by an arrow. In addition, as the content corresponding to the title "Settings", examples include items for selecting the display mode (display method), items for selecting the on / off of the display of the first digital vehicle speed display section 14, etc.

[0080] As Figure 10As shown in (E), the first content display unit 10 has a function of using a first perspective view that imitates the state of looking down on the vehicle from above the rear of the vehicle to display the positional relationship between the vehicle and surrounding vehicles or obstacles. The first horizon line 33 depicted between the ground and the sky in the first perspective view is displayed at the same position in the same shape as the first boundary line 32 when other information is displayed. That is, even when 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. In addition, the first boundary line 32 and the first horizon line 33 may not be exactly the same shape. Additionally, the title of the first perspective view may be, for example, "ADAS (Advanced Driver Assistance System) Information".

[0081] [2-8. Second Content Display Unit]

[0082] Figure 11 (A) of FIG. is a diagram showing the screen configuration of the second content display unit 15. Figure 11 (B) to (E) of FIG. are diagrams showing specific examples of the second content display unit 15.

[0083] The second content display unit 15 has at least a wider range than the first content display unit 10. Figure 11 As shown in (A) of FIG., the second content display unit 15 is shaped to expand upward to the range where the first output display unit 11 and the second output display unit 12 are arranged, with the position of the first content display unit 10 as a reference.

[0084] The second content display unit 15 has a second title display area 34 for displaying the title of the information, a second content display area 35 for displaying the content of the information, and a second boundary line 36 that divides them. The second boundary line 36 is a line that extends in the horizontal direction and divides 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.

[0085] Regarding the relationship between the first content display unit 10 and the second content display unit 15, the second title display area 34 is arranged above the first title display area 30, and the second boundary line 36 is arranged above the first boundary line 32. The size of the second content display area 35 is formed to be larger than that of the first content display area 31, and is, for example, shaped to magnify the first content display area 31 upward, leftward, and rightward.

[0086] The second content display unit 15 can display at least the same information as the first content display unit 10. Preferably, since it has a wider range than the first content display unit 10, it displays in larger characters, larger images, or displays more information or detailed information than the first content display unit 10. For example, Figure 11 The display example of (B) (content corresponding to the title "Drive Computer") is Figure 10 an example of magnifying the display content of (B).

[0087] Figure 11 The display example of (C) (content corresponding to the title "Energy Flow") is a detailed image 37 that illustrates the details of the information shown in Figure 10 (C). In this detailed image, the positions of the engine with a generator, the drive battery, the drive motor, and the drive wheels mounted on the vehicle are represented in a three-dimensional diagram, and the movement state of energy (driving force or electric power) is indicated by an arrow.

[0088] In Figure 11 the display example of (D) (content corresponding to the title "Settings"), not only the information shown in Figure 10 (D) but also a detailed image 38 for supplementing and explaining the information recorded in the second content display area 35 is added. For example, in a state where an item for selecting a display mode among the setting items displayed in the second content display area 35 is selected, a detailed image 38 that reduces the layout of each display mode is displayed.

[0089] In addition, as shown in Figure 11 (E), the second content display unit 15 has a function of using a second perspective view that imitates the state of looking down on the vehicle from above the rear of the vehicle to display the positional relationship between the vehicle and surrounding vehicles or obstacles. The viewpoint position in the second perspective view is preferably set to a position higher than the viewpoint position in the first perspective view. Thereby, the readability of the second perspective view is improved and a wider range of vision is obtained.

[0090] The second horizon line 39 drawn between the ground and the sky in the second perspective view is displayed at the same position in the same shape as the second boundary line 36 when other information is displayed. That is, even if the information displayed on the second content display unit 15 is switched, the second boundary line 36 and the second horizon line 39 do not change. In addition, the second boundary line 36 and the second horizon line 39 may not have exactly the same shape.

[0091] [3. Effects]

[0092] (1) The display device 1 of this embodiment includes: 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 in-vehicle devices. The first output display unit 11 is arranged in a range above the first content display unit 10, and represents the output of the vehicle by the length of a bar graph drawn therein. The second output display unit 12 is arranged in a range including at least the left and right sides and above of the first content display unit 10 and the first output display unit 11 on the outer periphery of the first content display unit 10 and the first output display unit 11, and represents the vehicle speed by the length of a bar graph drawn therein.

[0093] With such a structure, it is possible to display a variety of information easily, understandably, compactly, and efficiently, and improve the information density without impairing the understandability of the information. For example, as shown in (A) and (B) of Figure 4 , by arranging the second output display unit 12 on the outermost peripheral side in the rectangular display area, the first content display unit 10 and the first output display unit 11 can be arranged inside it without forcing. Therefore, it is possible to easily realize a display device 1 that is easy for users to observe, easy to understand the display content, and highly convenient.

[0094] (2) A first output left area 20 and a first output upper area 21 may be provided in the first output display unit 11. The first output left area 20 extends in the vertical direction to the left of the first content display unit 10. The first output upper area 21 extends in the right direction from the upper end of the first output left area 20 above the first content display unit 10. In addition, a second output left area 22, a second output upper area 23, and a second output right area 24 may be provided in the second output display unit 12.

[0095] The second output left area 22 extends in the vertical direction to the left of the first output left area 20. The second output upper area 23 extends in the right direction from the upper end of the second output left area 22 above the first output upper area 21. The second output right area 24 extends in the downward direction from the right end of the second output upper area 23 to the right of the first content display unit 10. With such a structure, the first output left area 20 and the second output left area 22 can be displayed side by side left and right, and the information density can be improved without impairing the understandability of the information. In addition, the convenience of the display device 1 can be further improved.

[0096] (3) The first remaining capacity display unit 13 may also be provided in the first display mode 4. The first remaining capacity display unit 13 is disposed adjacent to the lower side of the first output display unit 11 (the first output left region 20) to display information indicating the remaining capacity of the battery mounted on the vehicle. In this way, by disposing the first remaining capacity display unit 13 adjacent to the lower side of the first output display unit 11 (the first output left region 20), the information density can be improved without impairing the understandability of the information. In addition, the convenience of the display device 1 can be further enhanced.

[0097] (4) In a hybrid vehicle equipped with an electric motor that performs power running and regenerative power generation, a power region indicating the power consumption of the electric motor and a charging region indicating the charging power of the drive battery may also be provided in the first output display unit 11. In this case, as shown in (B) of Figure 6 , it may also be that the charging region is disposed at least in the first output left region 20, and the first remaining capacity display unit 13 is disposed adjacent to the lower side of the charging region.

[0098] With such a configuration, the relationship between the state of implementation of regenerative power generation in the electric motor and the remaining capacity of the drive battery charged as a result becomes clear at a glance, and information can be presented in an easily understandable manner. In addition, in Figure 6 the display example of (B), the elongation direction of the output during regeneration displayed inside the first output display unit 11 (the direction in which the negative output value increases) becomes the opposite direction to the elongation direction of the bar graph displayed inside the first remaining capacity display unit 13. Thereby, it is easy to intuitively understand the situation where the regenerative power is charged to the drive battery. In addition, the convenience of the display device 1 can be further enhanced.

[0099] (5) In the first display mode 4, the first digital vehicle speed display unit 14 that represents the vehicle speed numerically may also be provided separately from the second output display unit 12. In this way, not only the bar graph is displayed, but also the numerical vehicle speed is displayed together, so the information transmission efficiency can be improved. In addition, the convenience of the display device 1 can be further enhanced. In addition, since the numerical display does not require visual estimation of the length of the bar graph using scales and pointers as in the bar graph display, it is convenient when you want to grasp the vehicle speed instantaneously.

[0100] (6) Regions for additionally displaying information other than the numerical display region 25, such as a cruise control display region 26, a regulation display region 27, and a conversion value display region 28, may also be provided in the first digital vehicle speed display unit 14. The cruise control display region 26 is a region for displaying information related to cruise control that automatically increases or decreases the vehicle speed regardless of the driving operation. In addition, the regulation display region 27 is a region for displaying information related to the vehicle speed based on regulations, and the conversion value display region 28 is a region for displaying a value obtained by converting the vehicle speed of the vehicle into other units.

[0101] By setting the regions as described above, it is possible to easily present information in a limited space and improve the information density. In addition, the convenience of the display device 1 can be further enhanced. Furthermore, the regulation display region 27 and the conversion value display region 28 may be added only when such a display function is required for the destination of the vehicle. In addition, in a vehicle not equipped with a cruise control function, the cruise control display region 26 is not necessary. Moreover, the speed unit customary at the destination may not be the same as the speed unit easily understood by the user. Therefore, from the viewpoint of usability, the conversion value display region 28 may be standardly equipped in the first digital vehicle speed display unit 14 regardless of the destination.

[0102] (7) A first title display region 30 for displaying the title of the display information, a first content display region 31 for displaying the content of the display information, and a first boundary line 32 extending in the horizontal direction and dividing the first title display region 30 and the first content display region 31 in the vertical direction may also be provided in the first content display unit 10. With such a structure, by simply viewing the first title display region 30, it is possible to quickly grasp the meaning and theme of the information displayed in the first content display region 31. Therefore, the information density can be improved without sacrificing the understandability of the information. In addition, by drawing the first boundary line 32 between the first title display region 30 and the first content display region 31, each piece of information can be clearly separated and presented in a limited space. In addition, the convenience of the display device 1 can be further enhanced.

[0103] (8) As shown in (E) of Figure 10 , the first content display unit 10 may also have a function of using a first perspective view imitating the state of looking down on the vehicle from above the rear of the vehicle to display the positional relationship between the vehicle and surrounding vehicles or obstacles. In this case, it is preferable that the first horizon line 33 between the ground and the sky in the first perspective view is displayed at the same position as the first boundary line 32. In this way, by making the first horizon line 33 of the first perspective view and the first boundary line 32 coincide on the screen, even when the display content of the first content display unit 10 is switched, a sense of unity can be given to the display content, and various types of information can be easily displayed without giving the user a sense of incongruity. In addition, the convenience of the display device 1 can be further enhanced.

[0104] (9) The above-described display device 1 may also have a second display mode 5 including a second content display section 15, a third output display section 16, and a second digital vehicle speed display section 17. The second content display section 15 has a larger range than the first content display section 10 and is a part for displaying information indicating the driving state of the vehicle or the operating state of in-vehicle devices. The third output display section 16 is disposed below the second content display section 15 and is a part for representing the output of the vehicle by the length of a bar graph drawn therein. The second digital vehicle speed display section 17 is disposed above the second content display section 15 and is a part for representing the vehicle speed numerically. Additionally, preferably, the first display mode 4 and the second display mode 5 can be switched.

[0105] With such a configuration, compared with the first display mode 4, information indicating the driving state of the vehicle or the operating state of in-vehicle devices can be easily displayed in a large area and understood. For example, as shown in (A) and (B) of Figure 5 , a plurality of pieces of information can be displayed inside the wide second content display section 15, or information can be displayed using enlarged images and characters. Therefore, it is possible to easily implement the display device 1 that is easy for the user to observe, easy to understand the display content, and highly convenient.

[0106] (10) A second remaining capacity display section 18 may also be provided in the second display mode 5. The second remaining capacity display section 18 is disposed adjacent to the left of the third output display section 16 and displays information indicating the remaining capacity of the battery mounted on the vehicle. In this way, by disposing the second remaining capacity display section 18 adjacent to the left of the third output display section 16, the information density can be improved without impairing the understandability of the information. Additionally, the convenience of the display device 1 can be further enhanced.

[0107] (11) A cruise control display area 26, a regulation display area 27, a conversion value display area 28, etc. may also be provided in the second digital vehicle speed display section 17 in the same manner as the above-described first digital vehicle speed display section 14. By providing these areas, information can be easily presented and understood in a limited space, and the information density can be improved. Additionally, by making the content displayed on the first digital vehicle speed display section 14 and the content displayed on the second digital vehicle speed display section 17 consistent, the display content can be maintained before and after the switching between the first display mode 4 and the second display mode 5, and the convenience can be improved.

[0108] (12) A second title display area 34 for displaying the title of the display information, a second content display area 35 for displaying the content of the display information, and a second boundary line 36 extending horizontally and dividing the second title display area 34 and the second content display area 35 in the vertical direction may also be provided in the second content display section 15. In this case, preferably, the second boundary line 36 is disposed above the first boundary line 32.

[0109] According to the above structure, by simply viewing the second title display area 34, it is possible to quickly grasp the meaning and theme of the information displayed in the second content display area 35. Therefore, the information density can be improved without sacrificing the understandability of the information. In addition, 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. In addition, by arranging the second boundary line 36 above the first boundary line 32, the display area of the second content display area 35 can be expanded, the readability of the information can be easily improved, and the amount of information can be easily increased. In addition, the convenience of the display device 1 can be further improved.

[0110] (13) As shown in (E) of Figure 11 , the second content display unit 15 may also have a function of using a second perspective view imitating the state of looking down on the vehicle from above the rear of the vehicle to display the positional relationship between the vehicle and surrounding vehicles or obstacles. In this case, the second horizon line 39 between the ground and the sky in the second perspective view is preferably displayed at the same position as the second boundary line 36. In this way, by making the second horizon line 39 of the second perspective view and the second boundary line 36 coincide on the screen, even when the display content of the second content display unit 15 is switched, a sense of unity can be given to the display content, and various pieces of information can be easily displayed without giving the user a sense of incongruity. In addition, the convenience of the display device 1 can be further improved.

[0111] (14) For example, as shown in (B) of Figure 10 and (B) of Figure 11 , the second content display unit 15 may also display information that is substantially the same as the information displayed in the first content display unit 10. In addition, as shown in (C) of Figure 10 and (C) of Figure 11 , a detail image 37 that illustrates the details of the information displayed in the first content display unit 10 may also be displayed. Or, as shown in (D) of Figure 10 and (D) of Figure 11 , a detail image 38 for supplementary explanation that illustrates the details of the information displayed in the first content display unit 10 may also be displayed. In this way, by additionally displaying the detail images 37 and 38, the information can be presented in an easily understandable manner, and the convenience can be improved.

[0112] [4. Others]

[0113] The above embodiments are merely illustrative and are not intended to exclude various modifications and applications of technologies not explicitly shown in this embodiment. Each structure of this embodiment can be implemented with various modifications within the scope not departing from these main ideas. In addition, each structure of this embodiment can be selected for inclusion or exclusion as needed, or can be appropriately combined. For example, although the above-described display device 1 has a first display mode 4 and a second display mode 5, the second display mode 5 can be omitted. In addition, the display elements in the first display mode 4 and the second display mode 5 can be appropriately changed.

[0114] Figure 12 It is a diagram illustrating the minimum configuration of the screen of the first display mode 4. The first display mode 4 only needs to have at least a first content display unit 10, a first output display unit 11, and a second output display unit 12. In addition, the first output display unit 11 may be arranged in a range above the first content display unit 10. Furthermore, the second output display unit 12 may be arranged in a range including at least the left and right sides and above of the first content display unit 10 and the first output display unit 11 on the outer periphery of the first content display unit 10 and the first output display unit 11. With such a structure, it is possible to easily understand and compactly and efficiently present various kinds of information, and to improve the information density without sacrificing the understandability of the information. In addition, the convenience of the display device 1 can be improved.

[0115] Figure 13 It is a diagram illustrating the minimum configuration of the screen of the second display mode 5 when the second display mode 5 is set. The second display mode 5 only needs to have at least a second content display unit 15, a third output display unit 16, and a second digital vehicle speed display unit 17. In addition, the third output display unit 16 may be arranged below the second content display unit 15, and the second digital vehicle speed display unit 17 may be arranged above the second content display unit 15. With such a structure, it is possible to easily understand and compactly and efficiently present various kinds of information, and to improve the information density without sacrificing the understandability of the information. In addition, the convenience of the display device 1 can be further improved.

[0116] The 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 arbitrarily set. It can be considered that there are various combinations of the specific output information displayed on the first output display unit 11, the second output display unit 12, and the third output display unit 16.

[0117] Figure 14 It is a diagram showing a modified example (motor vehicle) of the first display mode 4. The specific content shown in the second output display unit 12 and the specific shape of the bar graph can also be appropriately changed. For example, as Figure 14 shown, the upper limit value of the vehicle speed displayed can be 200 km / h or more (Figure 14 When it is about 230 km / h, the length of the bar graph can also be extended according to the increase of the upper limit value. Figure 14 The shape of the extended part (lower right part) of the bar graph shown corresponds to the shape obtained by inverting the upper right part up and down. In addition, the same shape can also be applied to the lower left part of the bar graph to make the overall shape an octagonal shape.

[0118] With such a structure of the display screen, it is possible to ensure the length of the display area of the bar graph without impairing the sense of unity and design of the appearance. In addition, compared with the case where the bar graph is extended vertically downward, by extending the extended part (lower right part) of the bar graph obliquely downward to the left, the vertical dimension of the second output display unit 12 can be shortened. Therefore, such a structure of the display screen is useful when it is desired to dispose an indicator or the like below the second output display unit 12, and information can be displayed compactly and efficiently.

[0119] In addition, the above-described embodiment related to the hybrid vehicle can be applied to a plug-in hybrid vehicle (PHEV) capable of external charging or external power supply. A plug-in hybrid vehicle is a hybrid vehicle (hybrid electric vehicle, HEV, Hybrid Electric Vehicle) equipped with an engine and an electric motor as drive sources, a generator as a power generation device, and a battery as a power storage device, and having a structure capable of external charging of the battery or external power supply from the battery.

[0120] In the former plug-in hybrid vehicle, a charging port (inlet) for inserting a charging cable for delivering electric power from an external charging device, a non-contact power receiving device, etc. are provided. In the latter plug-in hybrid vehicle, an external power supply socket (outlet), a non-contact power supply device, etc. are provided. The above charging port and socket can also be provided together in one plug-in hybrid vehicle.

[0121] In addition, the layout of the first output display unit 11 and the second output display unit 12 can be reversed left and right with respect to the display area of the output device 3. For example, Figure 4The overall shape of the first output display unit 11 shown in (A) and (B) is the shape obtained by rotating the letter L 90 degrees clockwise (the rotated L shape), but the overall shape of the first output display unit 11 may also be the shape that is the mirror image of the shape obtained by rotating the letter L 90 degrees clockwise. In this case, the bar graph drawn inside the first output display unit 11 may also be reversed left and right in the same way, or it may not be. For example, the position of the origin (the scale indicating an output of 0) of the bar graph representing the output height may be set in the lower right part of the first output display unit 11, or may be set at the left end of the first output display unit 11. In addition, what is reversed 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 size do not need to be reversed left and right.

[0122] In addition, in Figure 8 In the second output display unit 12 shown, the position of the origin (the scale indicating a vehicle speed of 0) of the bar graph representing the vehicle speed height is arranged near the lower end of the second output left region 22, but the position of the origin may also be arranged near the lower end of the second output right region 24. That is, the change in vehicle speed may also be represented in such a way that the bar graph extends counterclockwise as the vehicle speed increases. In this way, the specific content shown in the first output display unit 11 and the second output display unit 12 and the specific shape of the bar graph are appropriately changed.
