[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configurations of the following embodiments are examples, and the present invention is not limited to the configurations of the embodiments.

[0011] <First Embodiment> FIG. 1 is a diagram showing the interior of a vehicle 1 equipped with an information display system 100 according to the first embodiment. The information display system 100 is mounted on the vehicle 1 and includes a CID (Center Information Display) device 10, a detection unit 20, vehicle equipment 30, an ECU (electronic control unit) 40, and a HUD (Head-Up Display) 50.

[0012] The CID device 10 is a form of a display device that acquires vehicle information from a detection unit 20 and an ECU 40 provided in the vehicle 1 and displays the vehicle information to the user. The CID device 10 may have a function of displaying an operation switch (hereinafter also referred to as a soft SW) on the display unit by software and operating the vehicle equipment 30 and the like according to an operation on the soft SW. Further, the CID device 10 may be provided as an audio device having an audio function or a navigation device having a navigation function.

[0013] The detection unit 20 is, for example, a sensor that detects vehicle information indicating the state of the vehicle 1, such as the vehicle speed, steering angle, shift position, brake operation state, headlight lighting state, door opening / closing state, interior light lighting state, seat belt lock / unlock information, own vehicle position, acceleration, temperature, humidity, etc. of the vehicle 1. Further, the detection unit 20 may be a sensor that detects vehicle information indicating the situation around the vehicle 1, such as a millimeter-wave radar, LiDAR (Light Detection and Ranging), a temperature sensor, an illuminance sensor, etc. Further, the detection unit 20 may be an imaging device that captures an image of the surroundings or inside the vehicle 1 to obtain a captured image. Furthermore, the detection unit 20 may be a microphone that generates sound information (electrical signal) according to the sound around or inside the vehicle 1.

[0014] The vehicle equipment 30 includes equipment that can be operated by the user, such as an air conditioner, a clearance sonar, a traction control, a rear camera, headlights, a defroster, a drive recorder, an emergency flashing indicator, etc.

[0015] The ECU 40 is connected to the CID device 10 via a communication line such as CAN, and transmits the operation state of the vehicle 1 detected by the detection unit 20 to the CID device 10. Further, the ECU 40 may detect the state of the vehicle equipment 30, such as the window glass opening / closing switch and the headlight switch, and function as a detection unit.

[0016] The HUD 50 provides a transparent screen above the dashboard 11, for example, on the front glass, and projects and displays vehicle information and the like on the screen. Note that the HUD 50 is not limited to the projection type and may be of other forms.

[0017] [CID Device] FIG. 2 is a diagram showing the schematic configuration of the CID device 10, FIG. 3 is a front view showing the state where the CID device 10 is attached to the vehicle 1, and FIG. 4 is a side view of the CID device 10. The CID device 10 includes a control unit 12, a memory 13, an input / output IF (interface) 14, a communication IF 15, a display unit 16, and a housing 19. The CID device 10 of the present embodiment is an information processing device (computer) that performs processing to display on the display unit 16 based on the information acquired from the detection unit 20 or the ECU 40. The housing 19 is disposed on the back side of the display unit 16 and houses the control unit 12, the memory 13, the input / output IF (interface) 14, and the communication IF 15.

[0018] The CID device 10 is attached to a predetermined mounting surface, in this embodiment, to the dashboard 11 of the vehicle 1. Specifically, the housing 19 is inserted into a slot 111 provided in the dashboard 11, and while most of the housing 19 is disposed inside the dashboard 11, the display unit 16 is attached in a state of being disposed outside (the passenger compartment side) of the dashboard 11.

[0019] The control unit 12 processes the input information and outputs the processing results, thereby controlling the entire device. The control unit 12 is also called a CPU (Central Processing Unit) or an MPU (Micro-processing unit). The control unit 12 is not limited to a single processor and may be a multi-processor configuration. It may also be a multi-core configuration with multiple cores on a single chip connected by a single socket.

[0020] Memory 13 includes main memory and auxiliary memory. Main memory is used as the work area of ​​the control unit 12, a storage area for temporarily storing information processed by the control unit 12, and a buffer area for communication data. Main memory is a storage medium for the control unit 12 to cache programs and data and expand the work area. Main memory includes, for example, RAM (Random Access Memory), ROM (Read Only Memory), and flash memory. Auxiliary memory is a storage medium that stores programs executed by the control unit 12, data used for information processing, and operation setting information. Auxiliary memory includes, for example, HDD (Hard-disk Drive), SSD (Solid State Drive), EPROM (Erasable Programmable ROM), flash memory, USB memory, and memory cards.

[0021] The input / output IF 14 is an interface for inputting and outputting data with other devices, such as the ECU 40. The input / output IF 14 performs data input and output with devices such as a disk drive that reads data from storage media such as CDs and DVDs, the detection unit 20, the vehicle equipment 30, and the ECU 40. The input / output IF 14 may receive information detected by the detection unit 20 or information from the vehicle equipment 30 directly from the detection unit 20 or the vehicle equipment 30, or it may receive it via the ECU 40. The operation unit 70 is an input means that detects user operations, generates operation information, and inputs it to the control unit 12 via the input / output IF 14. The operation unit 70 may be, for example, a touch panel provided on the display unit 16. The display unit 16 is an output means that displays vehicle information and other information to the user. The speaker 18 is an output means that outputs vehicle information, warnings, etc., as sound to the user.

[0022] Communication IF15 is an interface (communication module) that communicates with other devices via wired or wireless communication lines (network), and is also called a CCU (Communication Control Unit).

[0023] In the CID device 10 of this embodiment, the control unit 12 executes an application program, thereby enabling the control unit 12 to function as various processing units such as the vehicle information acquisition unit 121, the display control unit 122, the operation information acquisition unit 123, and the operation control unit 124. In other words, the control unit 12 can be used as various processing units depending on the software being executed. However, some or all of the above processing units are not implemented as hardware such as dedicated LSIs (large-scale integration) like DSPs (Digital Signal Processors), ASICs (Application Specific Integrated Circuits), FPGAs (Field-Programmable Gate Arrays), logic circuits, and other digital circuits. It may be configured in such a way. Furthermore, at least a part of each of the above-mentioned processing units may include an analog circuit. The control unit 12 may be configured in such a way that one processor functions as multiple processing units, or it may be configured in such a way that it comprises multiple processors, each functioning as a single processing unit.

[0024] The vehicle information acquisition unit 121 acquires vehicle information from the detection unit 20, vehicle equipment 30, or ECU 40 via the input / output IF 14. The vehicle information acquisition unit 121 acquires vehicle information such as vehicle speed, engine speed, whether the headlights are on high beam or not, shift position, outside temperature, room temperature, etc. Obtain the information.

[0025] The display control unit 122 displays vehicle information acquired by the vehicle information acquisition unit 121 on the display unit 16. The display control unit 122 also displays a map on the display unit 16 based on map information acquired from the auxiliary storage device. Furthermore, if a target value is entered by the user, the route from the current location to the destination may be displayed on the map. Note that the technology for determining the route based on the vehicle's position and vehicle driving information (vehicle information) can be based on known technology, so a detailed explanation is omitted.

[0026] The operation information acquisition unit 123 acquires operation information from the user via an operation unit 70, such as a touch panel, provided on the display unit 16.

[0027] The operation control unit 124 sends the operation information acquired by the operation information acquisition unit 123 to the vehicle equipment 30 and the control unit 12, and executes functions based on the operation information. For example, it operates functions such as the air conditioner, audio functions, and navigation functions in response to touch operations on the touch panel.

[0028] [Display] The display unit 16 includes a main display unit (first display unit) 61 that displays an image based on an image signal, and a transparent display panel 62 that includes a second display unit that displays an image based on an image signal different from the image signal for the main display unit 61 around the main display unit 61. The transparent display panel 62 is made of a transparent panel through which light can pass from the back to the front, at least in the display area. That is, the transparent display panel 62 is a so-called see-through type display unit through which the background is visible. The transparent display panel 62 of this embodiment is provided in front of the main display unit 61 and has a first region 601 through which the display image of the main display unit 61 is transmitted, and a second region 602 through which light can pass from the back to the front of the second display unit. On the other hand, the main display unit 61 is a display unit whose back side is shielded so that the background is not visible.

[0029] Figure 5A is a schematic cross-sectional view showing the configuration of the main display unit 61 and the transparent display panel 62. The transparent display panel 62 comprises a front protective plate 161, a touch panel 162, a display layer 163, and a rear protective plate 164. The front protective plate 161 and the rear protective plate 164 are highly rigid members that maintain the shape of the transparent display panel 160 and protect the touch panel 162 and the display layer 163. While it is preferable for the transparency of the front protective plate 161, touch panel 162, display layer 163, and rear protective plate 164 of the transparent display panel 62 to be as high as possible, it is not necessarily limited to the maximum transparency. For example, if the transparency of the material is 100%, the front protective plate 161, touch panel 162, display layer 163, and rear protective plate 164 may be formed with a transparency of less than 100% through surface treatment or coloring.

[0030] The touch panel 162 is, for example, a capacitive sensor that detects changes in capacitance as operation information when a user performs a touch operation. However, it is not limited to this; the sensor that detects operation information may be of other types, such as a resistive sensor or an infrared sensor.

[0031] The display layer 163 is a self-emissive display element such as an OLED (Organic Light Emitting Diode), in which pixels are arranged in a matrix, and each pixel displays an image. However, the display layer 163 may be a non-self-emissive display element such as a liquid crystal display element. In this case, a backlight may be provided on the back of the main display unit 61. The display layer 163 in Figure 5A is an example of a second display unit.

[0032] The main display unit 61 comprises a touch panel 166, a display layer 167, and a light-shielding layer 168. The touch panel 166 and the display layer 167 are the same as the touch panel 162 and the display layer 163 described above, so a further explanation is omitted. The light-shielding layer 168 allows the user to access the display layer 167 This is a non-transparent material that blocks light from the back side so that the background does not show through when viewing the displayed image.

[0033] In the example shown in Figure 5A, the main display unit 61 and the transparent display panel 62 are formed separately, but the invention is not limited to this, and the main display unit 61 and the transparent display panel 62 may be formed as a single unit. Figure 5B shows a display unit 16 in which the main display unit 61A and the transparent display panel 62A are formed as a single unit. As shown in Figure 5B, the transparent display panel 62A comprises a front protective plate 161, a touch panel 162, a display layer 163, a rear protective plate 164, and a light-shielding layer 168. Of these touch panel 162, display layer 163, and rear protective plate 164, the portion on the rear side with the light-shielding layer 168 is the main display unit 61A. Furthermore, of the front protective plate 161, the portion located in front of the main display unit 61A is the first region 601, and the portion located outside the first region 601 is the second region 602. A light-shielding layer 168 is provided on the back of the rear protective plate 164 that constitutes the main display unit 61A, and a housing 19 is attached to it, so that the back of the main display unit 61 is covered by the housing 19, and the transparent display panel 62A is held in the housing 19.

[0034] Each pixel in the display layer 163 is capable of emitting light in multiple primary colors, such as RGB, and by varying the brightness of these primary colors in multiple steps (gradations) and combining them, it can display multiple colors, including white. Furthermore, multiple display layers 163 may be provided. Figure 6 shows an example with two display layers 163 and 165. In Figure 6, in addition to the configuration of Figure 5B, a second display layer 165 is provided on the back of the first display layer 163. The second display layer 165 may be, for example, a liquid crystal display element that changes in multiple steps from transparent to black for each pixel. That is, the first display layer 163 displays RGB, and the second display layer 165 displays black. The second display layer 165 may, for example, black out pixels in the same locations as pixels displayed by the first display layer 163, thereby blocking light in those areas. In this case, the background will not show through in the areas displayed by the first display layer 163, and the display layer will no longer be transparent. In other words, the second region 602 of the transparent display panel 62 only needs to be transparent in areas where no display is being shown or at times when no display is being shown, and does not need to be transparent in areas where a display is being shown.

[0035] The display layer 163 is not limited to matrix-shaped display elements, but may also be segment-type display elements that display segments of a specific shape. For example, it may have a light-emitting segment in the shape of a soft switch, and the display layer may be configured to turn the segment on or off. Alternatively, it may be configured to represent characters or the state of a soft switch using a combination of segments.

[0036] Furthermore, in this embodiment, the main display unit 61 and the transparent display panel 62 are formed as a single unit, but this is not limited to this configuration. The main display unit 61 and the transparent display panel 62 may be formed as separate units, with the main display unit 61 positioned on the front side of the housing 19 and the transparent display panel 62 mounted around it.

[0037] As shown in Figure 3, when viewed from the front, the display unit 16 has an upper display area 621 of the transparent display panel 62 positioned above the main display unit 61. The lower display area 622 of the transparent display panel 62 is positioned below the main display unit 61, and the lateral display areas 623 of the transparent display panel 62 are positioned to the sides (left and right) of the main display unit 61. Thus, in this embodiment, the transparent display panel 62 extends outwards from the top, bottom, left, and right of the main display unit 61. In the case of a typical display unit, increasing the display area increases the feeling of being cramped. However, in this embodiment, because the outer portion of the display unit 16 is transparent, a large display area can be achieved while suppressing the feeling of being cramped. In particular, while a typical display unit cannot be placed above the dashboard 11 because the background is obscured, the transparent display panel 62 does not obstruct the driver's view and can therefore be placed above the dashboard 11.

[0038] Furthermore, as shown in Figure 4, the display unit 16 has a lateral section 64 extending from the upper edge of the main display unit 61 toward the rear side of the display unit 16, i.e., toward the front of the vehicle 1, and an upper display area 621 is erected on the front edge of the lateral section 64, facing diagonally upward toward the front. In other words, the display unit 16 has an S-shaped curve when viewed from the side. Thus, the upper display area 621 of the transparent display panel 62 is above the main display unit 61 and is positioned with a predetermined distance LA behind the display surface 611 of the main display unit 61. Also, as shown in Figure 3, the upper display area 621 of the transparent display panel 62 is spaced upward from the dashboard 11 and is positioned on the same line LA as at least a portion of the height of the display area 51 of the HUD 50, so that the user (driver) can check the display information of the HUD 50 and the display information of the upper display area 621 together. The upper display area 621 may extend straight upward from the main display unit 61, but as shown in Figure 4, it is provided by protruding to the rear side (front side of the vehicle) via the lateral section 64, so that it is positioned within the driver's forward field of vision and the information displayed in the upper display area 621 can be easily viewed while driving.

[0039] As shown in Figure 4, the lateral display area 623 of the transparent display panel 62 is positioned along the interior-side surface (mounting surface) 112 of the dashboard 11, at a predetermined distance LB from it. The lower display area 622 of the transparent display panel 62 is positioned below the dashboard 11 and is not overlapped with the dashboard 11 from the user's perspective. In this way, the lateral display area 623 and the lower display area 622 of the transparent display panel 62 are positioned away from the dashboard 11, making the displayed information appear to float and giving a novel impression.

[0040] The information displayed in the lateral display area 623 and the lower display area 622 is not particularly limited, but may include, for example, software switches for operating the functions of the CID device 10 or software switches for operating the vehicle equipment 30. The display unit 16 is also equipped with a touch panel (detection unit) 162, which can detect user touch operations on the display unit 16. For example, if software switches are displayed on the transparent display panel 62 and a user touches these software switches, the touch panel 162 detects this operation, and the control unit 12 controls the functions of the CID device 10 or the vehicle equipment 30. This allows operations on the CID device 10 and vehicle equipment 30 to be consolidated on the transparent display panel 62, and can be operated with a unified action such as touching the transparent display panel 62, thereby improving usability. In addition, by displaying software switches on the transparent display panel 62, even if many software switches are provided, a large transparent area can be used, reducing the feeling of being cramped.

[0041] As described above, in this embodiment, since the transparent display panel 62 is extended around the main display unit 61, even if the display area is enlarged, the transparent display panel 62 located near the outer edge is transparent, making it appear substantially smaller and reducing the feeling of being cramped.

[0042] <Second Embodiment> Figure 7 shows the configuration of the information display system 200 according to the second embodiment, and Figure 8 shows the configuration of the CID device 10A according to the second embodiment. This embodiment differs from the first embodiment described above in that it displays a warning when an object left in the storage compartment is detected, but the other configurations are the same. For this reason, elements similar to those in the first embodiment are denoted by the same reference numerals, and further explanation is omitted.

[0043] The information display system 200 of this embodiment, in addition to the configuration of the information display system 100 described above, is equipped with a storage tray 80 on the upper part of the center console. The storage tray 80 is provided at a spaced position below the second display unit and is one form of storage unit in this disclosure. The storage tray 80 has a peripheral wall 82 erected on the outer edge of the bottom plate 81, and a storage space 83 recessed from the top to the bottom is provided. The storage space 83 is for storing items such as smartphones and wallets. It is a space in which items can be stored. In this embodiment, storage in the storage tray 80 is not limited to completely placing items within the storage space 83, but also includes placing items on the bottom plate or otherwise positioning at least a part of the items within the storage space 83.

[0044] The CID device 10A includes an object detection unit 21 that detects objects stored in the storage tray 80. The object detection unit 21 emits an infrared signal toward the storage tray 80, receives the signal reflected by the object, and detects the presence or absence of an object based on this reflected signal. For example, if there is an object on the storage tray 80, the intensity of the received reflected signal will be higher (more light will be received) compared to when there is no object. Therefore, the object detection unit 21 can detect the presence or absence of an object based on the change in the reflected signal. Note that the object detection unit 21 is not limited to an infrared type, and may be a detection unit of other types, such as one that captures an image of the storage tray 80 and detects objects on the storage tray 80 by image processing, or one that detects objects using a ToF (Time of Flight) sensor or a three-dimensional scanner.

[0045] In addition to the configuration shown in Figure 2, the control unit 12 includes a disembarkation determination unit 125 for determining when a user has disembarked, a lost item determination unit 126, and a lost item warning unit 127.

[0046] The disembarkation determination unit 125 determines that the user has exited the vehicle 1 and that the use of the CID device 10A has ended. For example, the disembarkation determination unit 125 determines that the user has exited the vehicle when the vehicle information detected by the detection unit 20 satisfies predetermined conditions, such as when the accessory power of the vehicle 1 is turned OFF, the doors are locked, or the seat sensor no longer detects an occupant (the occupant has stood up). The disembarkation determination unit 125 is not limited to determining when the user has completely exited the vehicle 1, but may also determine the state immediately before the user exits. For example, the disembarkation determination unit 125 may determine that the user is about to exit when a predetermined time has elapsed since the accessory power was turned OFF, or when the doors are opened.

[0047] The lost item detection unit 126 determines whether or not there are any lost items in the storage tray 80. For example, if the disembarkation detection unit 125 determines that the user has disembarked, and there are items in the storage tray 80, the lost item detection unit 126 determines that these are lost items. The lost item detection unit 126 may also determine that items are lost if the number of items has increased compared to the state when the user last disembarked. In other words, items that were left behind since the user last disembarked do not need to be determined as lost items. The lost item detection unit 126 also attempts to connect with the user's smartphone via the communication IF 15 using NFC (Near Field Communication) or Bluetooth (registered trademark) with the communication range limited to the vicinity of the storage tray, and determines that there are lost items (smartphone) if a connection is possible when the user disembarks. In this case, the communication IF 15 functions as the object detection unit 21.

[0048] The lost item warning unit 127, when the lost item detection unit 126 determines that an item has been left behind, causes the display unit 16, namely the first display unit (main display unit 61) and the second display unit (transparent display panel 62), to display a warning indicating that an item has been left behind. For example, it may cause the upper display area 621 to flash, display a message such as "You have left something behind," or display an arrow moving from top to bottom in the side display area 623 and the lower display area 622 to warn the user that an item has been left behind. Note that specific displays such as flashing, message display, and moving arrow display may be performed in all or some of the display areas (upper, side, and lower) of the second display unit. In this example, the CID device 10 can make it easier for the user to notice that an item has been left behind by displaying a specific display in the lower display area 622, which is close to the storage tray 80, thereby reminding the user that they placed an item there.

[0049] Furthermore, if the CID device 10A detects a forgotten item and displays a warning after the accessory power is turned off, it may be equipped with a built-in battery to perform these operations. The ID device 10A may be connected to the vehicle's battery so that it can receive power even when the accessory power is OFF.

[0050] Figure 9 shows the flow of the display method executed by the control unit 12 of the CID device 10A. When power is supplied to the CID device 10A, such as when the accessory power of the vehicle 1 is turned ON, the control unit 12 starts the process shown in Figure 9. The control unit 12 then periodically executes the process shown in Figure 9 until the power supply is stopped.

[0051] In step S10, the control unit 12 acquires vehicle information of vehicle 1 from the detection unit 20 or the ECU 40.

[0052] In step S20, the control unit 12 determines whether the user has exited the vehicle 1 or is about to exit (these states are also referred to as the exit state), that is, whether the use of the CID device 10A has ended. For example, the exit determination unit 125 determines that the user has exited (affirmative determination) if the accessory power of the vehicle 1 is turned OFF and the doors of the vehicle 1 are locked. If the determination in step S20 is negative, the control unit 12 terminates the process shown in Figure 9, and if the determination in step S20 is affirmative, it proceeds to step S30.

[0053] In step S30, the control unit 12 determines whether or not there is a forgotten item based on the detection result of the object detection unit 21. If the control unit 12 determines in step S30 that there is no forgotten item, it terminates the process shown in Figure 9. If the control unit 12 determines in step S30 that there is no forgotten item, it proceeds to step S40.

[0054] In step S40, the control unit 12 causes the display unit 16 to display a warning indicating that an item has been left behind. In addition to the warning display, a warning sound or voice message may also be output from the speaker. When the warning is displayed on the transparent display panel 62 in this way, the transparent display panel 62 is located on the outer edge of the display unit 16, making it easily visible to users who have disembarked or are about to disembark, thus making the user aware of the item they have left behind.

[0055] In this embodiment, the CID device 10A determines that an item such as a smartphone is lost if it is found in the storage tray 80 when use has ended, and displays a warning on the display unit 16. This warns the user and prevents them from leaving behind their smartphone, wallet, or other items.

[0056] <Variation> Figure 10 shows a modified CID device 10B. In the second embodiment described above, the information display system 200 was equipped with a storage tray (storage section) 80 that was configured separately from the CID device 10A. In this modified example, the CID device 10B is equipped with the storage section. Note that the other components are the same as in the first embodiment described above, so the same elements are denoted by the same reference numerals and further explanation is omitted.

[0057] As shown in Figure 10, the CID device 10B has a storage tray (storage section) 180 provided on the lower front side of the housing 19 via a stay 182 that extends downward. That is, the storage tray 180 is located below the transparent display panel 62.

[0058] In this modification, when the storage tray 180 is positioned below the display unit 16, the stored items are easily hidden by the display unit, making it easy for items to be forgotten. In contrast, in this modified example, the transparent display panel 62 is transparent, so the items stored in the storage tray 180 are not hidden, thus preventing items from being forgotten. In this modified example, the configuration other than the storage tray 180 is the same as in the first embodiment, but it is not limited to this, and it may also be the same as in the second embodiment, with a configuration that detects forgotten items on the storage tray 180 and displays a warning.

[0059] Although embodiments of the present invention have been described above, these are merely illustrative examples, and the present invention is not limited thereto. Various modifications based on the knowledge of those skilled in the art are possible, as long as they do not depart from the spirit of the claims. [Explanation of Symbols]
