Abstract
Description
[Technical Field]
[0001] The present invention relates to an in-vehicle electronic device that employs a touch panel input method. [Background technology]
[0002] Regarding in-vehicle electronic devices that employ this type of input method, for example, as shown in FIG. 24(A), a technology has been proposed in which a sheet plate displaying operation contents is attached to a touch panel section that is detachable from the monitor body, and in-vehicle equipment can be selected and the operating mode of the selected equipment can be specified by touching a predetermined point on the sheet plate (Patent Document 1).
[0003] Furthermore, as shown in Figure 24(B), by providing a protrusion on the front of the touch panel so as to surround the operation switch display area, the operation switch display is not obscured by the step of the protrusion, and by positioning the protrusion in the switch inoperable area of the touch panel, the switch will not operate even if the protrusion is pressed, and there is also a proposal for a technology that prevents incorrect operation switch input (Patent Document 2).
[0004] Furthermore, as shown in Figure 24(C), in a touch panel device in which multiple transparent electrodes are formed on a touch panel substrate and connecting electrodes are individually connected to each of the transparent electrodes to form multiple electrostatic touch switches, each transparent electrode is formed on the touch panel substrate so that the outside of one transparent electrode is surrounded by other transparent electrodes, and a connecting electrode is connected to the outer edge of each of these outer transparent electrodes as viewed from the inner transparent electrode, and a tongue portion is formed integrally with the inner transparent electrode that passes between the outer transparent electrodes, and a connecting electrode is connected to the tip of the tongue portion, thereby making the shadow caused by the connecting electrode connected to the transparent electrode less noticeable (Patent Document 3).

[0005] [Patent Document 1] JP 6-110609 (Abstract, Figures 2, 4, and 6) [Patent Document 2] Patent Publication No. 2006-350789 (Abstract, Figure 2) [Patent Document 3] Patent Publication No. 2012-123449 (Abstract, Figures 2 and 3) Summary of the Invention [Problem to be solved by the invention]
[0006] These conventional technologies have the problem that complex touch detection areas must be set on the touch panel to realize various functions installed in the in-vehicle electronic device, making it difficult to apply these conventional technologies to compact in-vehicle electronic devices that take design into consideration.
[0007] Therefore, the present invention aims to provide a technology that enables various inputs without complexly setting the touch detection area in an in-vehicle electronic device that uses a touch panel input method, and that can be applied to compact in-vehicle electronic devices. [Means for solving the problem]
[0008] The in-vehicle electronic device of the present invention, which has been made to achieve the above-mentioned object, is characterized by comprising a display screen having a touch panel on the front, a control device that displays images on the display screen and performs various arithmetic processing based on touch operations on the touch panel, and also has the following configuration. (1) The touch panel has a plurality of sensor areas that divide the display screen along a predetermined direction, and the control device has a touch operation determination means that inputs the touch status of the plurality of sensor areas and determines whether the touch operation is a one-touch, long press, or flick.
[0009] For example, the sensor area is provided so as to divide the screen in one of the directions, such as left and right, up and down, diagonally, etc. By dividing the screen in a predetermined direction, it is possible to distinguish between touch methods that are ambiguous based on the user's senses, such as around the middle, left side, right side, top side, bottom side, etc., and to determine touch operations. If the screen were divided into squares or the like, a fairly accurate touch would be required, but since the screen is simply divided equally in a predetermined direction, the desired operation can be performed even with an ambiguous touch in terms of position.
[0010] Here, the in-vehicle electronic device of the present invention may be configured as follows. (2) The touch operation determination means is configured as a means for determining the type of touch operation based on the touch position, release position, and touch time.
[0011] It is possible to determine whether a flick operation is occurring based on whether the touch position and release position are the same or different. It is also possible to distinguish between a single touch and a long press based on the length of time from touch to release.
[0012] The in-vehicle electronic device of the present invention may be configured as follows. (3) The touch panel has a sensor area that divides the display screen into three parts in the vertical or horizontal direction.
[0013] Even on a fairly small screen, users will not find it difficult to use if they touch the center or near the edge. Furthermore, if the screen is divided equally, it will be even easier for users to operate.
[0014] The in-vehicle electronic device of the present invention may further include the following configuration. (4) The control device is provided with a display state switching means for switching between a first display state that uses the entire display screen and a second display state that displays an image in units of the sensor area.
[0015] The screen can be used for different purposes, such as using the entire screen for the standby screen, and using the sensor area for the settings screen.
[0016] Furthermore, the in-vehicle electronic device of the present invention may also have the following configuration. (5) When displaying an image in units of the plurality of sensor areas, the control device is configured to display the entire image in at least one sensor area, and to display a partial image in the sensor area adjacent to the sensor area in which the entire image is contained, so that the display state is biased away from the sensor area in which the entire image is contained.
[0017] For example, if the screen is divided into three parts horizontally, the screen corresponding to the center sensor area can be used to display an icon image representing the current setting item so that it fits entirely within the sensor area, and the right sensor area, which can be displayed by scrolling left, can display an icon for another setting item so that it is slightly visible.This allows, for example, when trying to move the icon image in the right sensor area to the center, the right sensor area can be reliably touched and flicked to the left, so that such partial image display improves operability and gives the user the feeling that the screen is switching smoothly.
[0018] Furthermore, the in-vehicle electronic device of the present invention may also have the following configuration. (6) The control device is provided with a setting condition selection screen display means for displaying a selection screen for various setting conditions for the in-vehicle electronic device by switching the image display content on the display screen based on the judgment result of the touch operation judgment means.
[0019] In-vehicle electronic devices are required to be able to change various settings according to the user's preferences and usage conditions. On the other hand, there are users who want to display their preferred standby screen after completing the settings. Therefore, if the standby screen is displayed normally and a selection screen for various setting conditions is displayed when a certain touch operation is performed, the in-vehicle electronic device will be able to accurately meet the user's needs.
[0020] In this case, it is preferable to further include the following configuration. (7) The control device has, as the setting condition selection screen display means, a means for scrolling the screen to switch setting items when the touch operation determination means determines that the operation is a flick operation, and a means for forwarding the screen to switch setting conditions for the setting items when the touch operation determination means determines that the operation is a one-touch operation.
[0021] This is because various setting conditions for many setting items are determined in advance, and the setting conditions for the setting items desired by the user can be displayed by scrolling and turning the screen. The user's operations for this are one-touch and flick, so the scrolling and turning of the screen can be commanded intuitively.
[0022] Furthermore, the in-vehicle electronic device of the present invention may also have the following configuration. (8) The control device includes a long press response processing means for changing or confirming a display or setting state when the touch operation determination means determines that the touch operation is a long press.
[0023] When selecting the settings as described above, the user needs to finally set the desired settings. Also, the user needs to switch from the standby screen to the settings screen at the desired timing. In such cases, long press is intuitively suitable for switching between these displays and confirming the settings. [Effects of the Invention]
[0024] According to the present invention, in an in-vehicle electronic device that employs a touch panel input method, it is possible to provide a technology that enables various inputs without complexly setting the touch detection area, and that can be applied to compact in-vehicle electronic devices.

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific examples of the present invention will be described in detail with reference to the accompanying drawings. [Example]
[0027] As Example 1, we will explain an information display device 1, which is an in-vehicle electronic device for monitoring and displaying speed enforcement information. As shown in Fig. 1, this information display device 1 has a main body case 2 with a dice-shaped outer shape that is approximately equal in width, height, and depth, and is used by fixing it to any position on the dashboard via a support bracket 5.
[0028] The support bracket 5 is composed of a base member 5a that is attached to the dashboard by adhesion or suction, and a support member 5c that is connected to the base member 5a via a ball joint mechanism 5b. Four outward claws 6a to 6d protrude from the top surface of the support member 5c. The information display device 1 is attached by fitting these four outward claws 6a to 6d into four fitting portions 3a to 3d formed on the bottom surface of the main body case 2, and the information display device is installed on the dashboard by the base member 5a.
[0029] By attaching a support bracket 5, the information display device 1 can be rotated in any direction as shown by the arrows in Figures 1(C) to (D), and can be installed on the dashboard at an angle that is easy for the user to see.
[0030] As shown in FIG. 2, the information display device 1 has a display unit 10 on the front surface 2a, the aforementioned fitting portions 3a to 3d formed on the bottom surface 2b, push buttons 11 to 13 on the top surface 2c, an SD card insertion port 14 and an external input terminal insertion port 15 formed on the right side surface 2d, an exposed slide switch 16 and a DC jack insertion port 17 formed on the back surface 2f, and a main body case 2 with a dice-shaped external shape that is approximately equal in width, height, and depth.
[0031] 3, the main case 2 is constructed as an assembly of an upper case 21 integrally formed with a top surface 2c, a right side surface 2d, a left side surface 2e, and a back surface 2f, a bottom case 22 constituting the bottom surface 2b, and a front case 23 constituting the front surface 2a. At this time, the front case 23 is assembled by fitting its upper edge 23a and lower edge 23b behind an upper front edge 2g formed on the front part of the top surface of the upper case 21 and a lower front edge 2h formed on the front surface of the bottom case 22, and the main case 2 is assembled by fastening the upper case 21 and the bottom case 22 together with screws at four locations from below. The upper case 21, bottom case 22, and front case 23 are each manufactured integrally by synthetic resin injection molding.
[0032] At this time, a first board 31, which is equipped with a radar module 31a and a DC jack receptacle 31b and has a patch antenna 31c attached to its back surface, is fixed to the bottom case 22 from above with screws parallel to the bottom surface. A second board 32, which is equipped with a GPS module 32a, slide switch components 32b, a built-in speaker 32c, a backup battery 32d, and three tactile switches 32e-32g, is positioned so as to hang parallel to the top surface of the upper case 21 and is fixed to the bottom case 22 with screws from the back surface. A third board 33, which is equipped with an SD card slot component 33a, an external input terminal receptacle 33b, and an FM transmitter 33c, is sandwiched between support posts 22a-22d erected from the four corners of the bottom case 22 and four screw-receiving legs 21a-21d (see FIG. 4) hanging downward from the upper case 21 corresponding to the support posts 22a-22d. As a result, the first to third substrates 31 to 33 are all stored inside the main body case 2 at intervals in the height direction, with the plate surfaces facing up and down in a horizontally mounted state.
[0033] The front case 23 has a rectangular opening 23c that constitutes the display unit 10, and a display board 34 having a liquid crystal display 34a and a liquid crystal shield 34b mounted thereon is fixed with screws to the rear side, and an electrostatic touch panel 41 is fitted to the front side, with the front case 23 fitted inside the upper case 21 and the bottom case 22. As a result, the display board 34 is stored inside the main case 2 in a vertical position with its plate surface facing in the front-to-rear direction. A main control microcomputer including a CPU is also mounted on the rear side of the display board 34.
[0034] When the first board 31 is fixed to the upper case 21 with screws, elastomer push button parts 42 that operate the tactile switches 32e to 32g are attached, and the push buttons 11 to 13 are assembled so that they are exposed from the switch exposing openings 21e to 21g formed on the top surface of the upper case 21. A serial number sticker 43 is affixed to a rectangular recess 21h formed on the back surface of the upper case 21.
[0035] Of the boards housed within the main body case, the second board 32 and the third board 33 are connected by a BtoB connector, and the other boards are connected to each other by flexible flat cables. Therefore, during assembly, the third board 33 is connected via a BtoB connector to the underside of the second board 32, which is fixed with screws to the back surface of the upper case 21, the first board 31 is fixed with screws to the bottom of the bottom case 22 from above, and the display board 34, which is fixed with screws to the back surface of the front case 23, and the first board 31 and the third board 33 are connected with flexible flat cables, and then the front case 23 is sandwiched between the bottom case 22 and the upper case 21 and fixed with screws to perform assembly.
[0036] 4 shows perspective views of the upper case 21 as viewed from various directions. The aforementioned screw receiving legs 21a to 21d are integrally formed so as to hang down from the four inner corners of the top surface 2a of the upper case 21. Short screw receiving legs 21i to 21l are also integrally formed so as to hang down from positions inward in the front-to-rear direction relative to the screw receiving legs 21a to 21d. These short screw receiving legs 21i to 21l are used to secure the four corners of the second board 32 from below with screws. The second board 32 is positioned in the height direction by the lower ends of these short screw receiving legs 21i to 21l.
[0037] The right side surface 2d of the upper case 21 is formed with a long, narrow groove-like opening 21m that forms the SD card insertion slot 14, and a circular opening 21n that forms the external input terminal insertion slot 15. The back surface 2f of the upper case 21 is formed with a rectangular opening 21o that exposes the slide switch 16, and a circular opening 21p that forms the DC jack insertion slot 17. As shown in the figure, the rectangular opening 21o and the circular opening 21p on the back surface 2f are spaced apart in the vertical and horizontal directions.
[0038] Vertical ribs 21q and 21r are also integrally formed between the upper front edge 2g of the upper case 21 and the front screw-receiving legs 21a and 21b so as to protrude from the left and right side surfaces 21d and 21e. These vertical ribs 21q and 21r serve to position the rear surface of the front case 23 in the front-rear direction.
[0039] Furthermore, sound emission holes 21s are formed in a grid pattern at equal intervals on the top surface 2c of the upper case 21 to correspond to the installation positions of the built-in speakers 32c. Furthermore, recesses 21t are formed in a grid pattern at equal intervals on the left, right, and center of the sound emission holes 21s. A total of 3 × 18 sound emission holes 21s and recesses 21t are formed, with 3 × 10 recesses 21t on the left side and 3 × 3 recesses 21t on the right side. Of these 3 × 5 recesses 21t, 14 are sound emission holes 21s, excluding the center recess 21t, and the center recess 21t is also formed. By forming recesses 21t in addition to the sound emission holes 21s, the design does not make the speaker location stand out externally.
[0040] An oval cylindrical wall 21u hangs down from the back side of the top surface 2c so as to surround the sound emission hole 21s, and a long-legged oval cylindrical wall 21v hangs down from the outside of the oval cylindrical wall 21u. The inner oval cylindrical wall 21u abuts against the upper edge of the built-in speaker 32c, and the outer oval cylindrical wall 21v abuts against the side of the built-in speaker 32c, forming a void on the back side of the top surface 2c of the upper case 21 for sound to resonate without being dispersed within the main case.
[0041] 5 shows perspective views of the bottom case 22 viewed from various directions. The aforementioned support posts 22a to 22d are integrally formed at the four corners of the inside of the bottom case 22 so as to stand upright in the vertical direction. Directly below these support posts 22a to 22d, screw insertion holes 22e to 22h are formed, into which screws can be inserted from the bottom side. By inserting screws into these screw insertion holes 22e to 22h and screwing them into the screw-receiving legs 21a to 21d of the upper case 21, the third board 33 is sandwiched between the support posts 22a to 22d of the bottom case 22 and the screw-receiving legs 21a to 21d of the upper case 21, thereby positioning it in the height direction and assembling it so that it is horizontal.
[0042] Short bosses 22i to 22l are formed to protrude from the inside of the bottom surface of the bottom case 22 at inner positions in the front-rear direction of the support posts 22a to 22d. These short bosses 22i to 22l are used to screw and fix the first board 31. The first board 31 is positioned near the bottom surface by these short bosses 22i to 22l and fixed in a horizontal state.
[0043] In order to form the fitting portions 3a-3d, stepped rectangular holes 22m-22p, the front half of which is a wide rectangle and the rear half of which is a rectangle of half the width, are formed on the bottom surface of the bottom case 22, and stepped rectangular surfaces 22q-22t, which are shaped like the stepped rectangular holes 22m-22p but with the front and rear reversed, are integrally formed on the inner surface so as to be stepped upward. The outward claws 6a-6d of the support bracket 5 enter the fitting portions 3a-3d from the wide portions of the stepped rectangular holes 22m-22p, and by moving the information display device 1 so as to shift relatively forward, they move to the narrow portions of the stepped rectangular holes 22m-22p, thereby preventing it from coming out. By reversing the front-to-back directions of the stepped square holes 22m-22p and the stepped square surfaces 22q-22t, the fitting portions 3a-3d, which can be configured to have a retained state and a removable state by moving back and forth, can be integrally molded by injection molding.
[0044] A rectangular recess 22v equipped with a partition 22u is formed in the center of the rear bottom surface of the bottom case 22. The inside of this rectangular recess 22v is closed by a flat plate portion 22w with a stepped upper portion. In addition, semicircular cross-sectional grooves 22x extending in the front-rear direction are formed immediately inside and in the center of the stepped square holes 22m-22p. A front-rear rib 6x protruding from the upper surface of the support portion 5c of the support bracket 5 and a rear-end elastic piece 6v with a claw (see FIG. 1) fit into these rectangular recesses 22v and semicircular cross-sectional grooves 22x, thereby fulfilling the function of positioning in the front-rear and left-right directions.
[0045] Note that cross-shaped protrusions 22y, 22y are formed between the lower front edge 2h of the bottom case 22 and the front support columns 22a, 22b, and are structured to position the lower rear end of the front case 23. In addition, spherical recesses 22z, 22z are formed on the front right and rear left of the central semicircular cross-sectional groove 22x.
[0046] 6 shows perspective views of the front case 23 viewed from various directions. As already mentioned, the front case 23 has an upper edge 23a that fits behind the upper front edge 2g of the upper case 22, a lower edge 23b that fits behind the lower front edge 2h of the bottom case 22, and a rectangular opening 23c in the center. This rectangular opening 23c is formed by a rectangular frame 23d. The electrostatic touch panel 42 is sized to fit inside this rectangular frame 23d. The electrostatic touch panel 42 is positioned in the front-to-rear direction by a frame-shaped receiving portion 23e that is integrally molded to protrude inside the rectangular frame 23d. Bosses 23f to 23i that are used to screw the display board 34 from the rear side are integrally molded on the rear surface of the frame-shaped receiving portion 23e. The front surface of the front frame 23j, which is formed so as to protrude slightly outward from the front surface of the rectangular frame 23d, becomes the front surface 2a of the main body case 2, and when assembled, it is flush with the lower end of the upper front edge 2g of the upper case 21 and the upper end of the lower front edge 2h of the bottom case 22.
[0047] Next, the morphological features of the main body case 2 will be described using cross-sectional views.
[0048] FIG. 7 shows a cross-sectional view taken along the line AA of the sound output hole 21s and the recess 21t, as well as a plan view showing the cutting position and the direction of the arrow. As shown, the upper surface of the upper case 21 has recesses 21t that are approximately one-third the thickness of the wall. The sound output holes 21s and recesses 21t penetrate the upper surface and are spaced equally apart. The inner oval cylindrical wall 21u abuts against the top surface of the built-in speaker 32c, forming a cavity 32v inside. The outer oval cylindrical wall 21v abuts against the side of the built-in speaker 32c, creating a double-surrounded cavity 32v. Sound output from the built-in speaker 32c resonates within the cavity 32v and is emitted to the outside through the sound output hole 21s. The cavity 32v resembles the body of a guitar or violin.
[0049] The side surfaces 2d and 2e are shaped to bulge outward via upper and lower tapered step portions 2d1 and 2e1, with partial bulges 2d2 and 2e2 formed at the top and bottom. These bulges 2d2 and 2e2 create an outward bulge in the main case 2, giving the main case 2 a sense of volume. This sense of volume is further emphasized by the presence of narrowed portions 2d3 and 2e3 in the middle of the height direction. In FIG. 7, reference numeral 2e4 denotes a recess formed as a concave portion for a logo or the like. This recess 2e4 for a logo or the like is formed as needed, and may be formed on a flat surface as shown in FIGS. 1 to 6.
[0050] FIG. 8 is a cross-sectional view taken along the line B-B, taken along a line passing through the three push buttons 11-13, and a plan view showing the cross-sectional position and the direction of the arrow. As in the cross-sectional view A-A, the side surfaces 2d and 2e have tapered steps 2d1 and 2e1, bulges 2d2 and 2e2, and narrowed portions 2d3 and 2e3, which give the push buttons 11-13 a sense of volume. The push buttons 11-13 abut against tactile switches 32e-32g mounted on the second substrate 32. The top surface 2c has raised ribs 2c1-2c3 formed on it, surrounding the push buttons 11-13. Because the ribs 2c1-2c3 surround the push buttons 11-13, the height of the push buttons 11-13 is not noticeable.
[0051] The SD card slot part 33a is attached so that its tip is exposed from the elongated groove-shaped opening 21m on the right side surface 2d. The elongated groove-shaped opening 21m is surrounded by a recess 21m1 that is approximately half the thickness of the wall. The formation of this recess 21m allows for smooth insertion and removal of the SD card. Note that in FIG. 8, the reference numeral 2d4 also represents a depression such as a logo formed as a recessed portion, and it may be formed on a flat surface as in FIGS. 1 to 6.
[0052] FIG. 9 is a cross-sectional view taken along the line CC, cut through the central push button 12, and a plan view showing the cut position and the direction of the arrow. It can be seen that the front and rear edges of the top surface 2c and the bottom surface 2b of the main body case 2 are made up of rounded curved surfaces 2c4, 2c5, 2b1, and 2b2. The presence of these curved surfaces 2c4 and others gives the information display device 1 a smooth, soft appearance without any angular edges. While this embodiment has a rectangular recess 21h on the back surface 2f for affixing a serial number sticker 43, a flat back surface without a recess may also be used.
[0053] Figure 10 is a cross-sectional view taken along the line DD, cut horizontally at the center in the front-to-rear direction, and a plan view showing the cut position and the direction of the arrow. From this figure, it can be seen that the side surfaces 2d and 2e have tapered steps 2d1 and 2e1, bulges 2d2 and 2e2, and narrowed portions 2d3 and 2e3, which give the device a sense of volume. The symbol 2d5 written above the card slot indicates the type of SD card in engraved form, but this may also be a flat surface, as shown in Figures 1 to 6.
[0054] Next, the positional relationship between the boards 31 to 34 will be described with reference to FIG. 11, which shows a state in which the upper case and front case have been removed.
[0055] As shown in the figure, the first to third substrates 31 to 33 are installed horizontally with their surfaces facing up and down and spaced apart in the vertical direction, while the display substrate 34 is installed vertically with its surface facing forward and backward.
[0056] The GPS module 32a is mounted on the top surface of the first board 32, which is mounted horizontally at the top, making it easy to receive radio waves from GPS satellites. Meanwhile, the radar module 31a, which is the heaviest component, is mounted on the bottom first board 31, allowing the device's center of gravity to be low. The SD card slot component 33a and external input terminal receptacle component 33b of the third board 33 face to the right, making it easy for the user in the driver's seat to insert and remove an SD card or an output terminal for a portable music player or the like.
[0057] In addition, patch antenna 31c is installed upright on the back side of first board 31, which is attached at the bottom, making it easy to catch microwaves and other signals from the front of the vehicle. Furthermore, slide switch component 32b is installed near the left rear end of second board 32, which is the top, and DC jack receptacle component 31b is installed near the right rear end of first board 31, which makes the DC jack and slide switch less noticeable from the front and can be placed at positions separated vertically and horizontally on the back. This prevents the power cord of the DC jack from being accidentally unplugged when operating the slide switch.
[0058] Unlike the first to third substrates, the display substrate 34 is attached vertically, so that the four substrates can be efficiently housed within the compact main body case 2.
[0059] According to the information display device 1 of Example 1, the main body case 2 is configured with a dice-shaped external shape with approximately the same width, height, and depth, which adds to the design interest, and by attaching the first to third boards 31 to 33 with their plate surfaces facing up and down, the electronic components for performing the original functions of the information display device 1 can be neatly stored inside the dice-shaped main body case. As a result, an information display device can be provided that does not impede the original functions from being performed, and that is attractive as an interior decoration for a vehicle due to the "solid feel" of the dice shape.
[0060] Furthermore, by placing the first board 31, on which the relatively heavy radar module 31a is mounted, at the bottom, the weight balance of the entire device is improved, and the forward tipping moment caused by the weight of the display unit 10 attached to the front is canceled out. Furthermore, since the GPS module 32a is mounted on the uppermost second board 32, it is easy to receive radio waves from GPS satellites. In addition, a patch antenna 31c is installed on the back side of the first board 31, standing upright so as to be approximately parallel to the back surface 2f of the main body case 2, which enables a compact design while maintaining sufficiently high detection capabilities of the radar module 31a.
[0061] Furthermore, a slide switch component 32b is installed on the left rear end of the top second board 32, and a DC jack receiving component 31b is installed on the right rear end of the bottom first board 31, making it easy to turn the power on / off and preventing the power cord from coming loose when touching it.
[0062] Additionally, by installing third substrate 33, the device can function as a music player while still being an in-vehicle information display device, thereby providing interesting functionality in addition to an interesting design. Push buttons 11-13 required to activate the added music playback function are located in the front half of the top surface of main body case 2 and are surrounded by protruding frames 2c1-2c3, so the design is not compromised, operability is good, and the buttons can be operated without having to touch the switches or power cord on the back.
[0063] Furthermore, the built-in speaker 32c is installed on the upper surface of the uppermost second substrate 32, and the sound emission holes 21s are formed in a grid pattern on the upper surface 2c of the main body case 2, and the recesses 21t give the design a sense of unity, making the speaker less conspicuous. A void 32v surrounded by oval cylindrical walls 21u and 21w is provided between the speaker 32c and the sound emission holes 21s, allowing sound to resonate well, and audio information such as warnings and cautions can be reliably conveyed to the driver through the speaker sound.
[0064] The main body case 2 is constructed by assembling an upper case 21 whose top, sides and back are integrally formed, a bottom case 22 which forms the bottom, and a front case 23 which fits behind an upper front edge 2g formed on the front part of the top surface of the upper case and a lower front edge 2h formed on the front surface of the bottom case, and is configured so that a display board 34 equipped with an LCD display 34a is attached to the back side of the front case 23, so that the main body case 2 is easy to assemble while having a sturdy structure, and the display panel can be securely attached.
[0065] In addition, since a touch panel 41 is attached to the front side of the display opening of the front case 23, various settings can be made naturally along with the contents of the display, and the adverse effect on design caused by providing switches, etc. can be eliminated.
[0066] Furthermore, the front and rear edges of the top surface and the front and rear edges of the bottom surface of the main body case 2 are made up of rounded curved surfaces 2c4, 2c5, 2b1, 2b2, which gives a smooth, "solid" impression, and makes it possible to predict the direction in which the case will likely roll if it were to roll, while also giving the user a "sense of security" that it will not hurt even if it hits them.
[0067] Furthermore, even though it is a speed enforcement monitoring device, the main body is dice-shaped, giving it a sense of "solidity," "solidity," and "mechanical impression," making it easy to accept as part of the interior of a car without feeling out of place.
[0068] Furthermore, the information display device 1 of the first embodiment realizes a music playback function by a main control microcomputer mounted on the back of the display board 34. Specifically, music data is read from an SD card inserted in the SD card slot, played, and output via the FM transmitter 33c, allowing the music to be played through the speakers of the in-car audio system. This music playback is performed by operating the push buttons 11 to 13 on the top surface to issue song selection and playback commands such as pause / play, rewind, and fast forward. Note that even when an external device such as a portable music player is connected to the external input terminal and music is played from the external device, the music can be transmitted to the in-car audio system via the FM transmitter 33c and enjoyed comfortably through the in-car speakers.
[0069] Next, the control system of the information display device 1 will be described. As shown in FIG. 12, the control system of this information display device 1 is centered around a microcomputer 50 for display control. The microcomputer 50 receives signals from the radar module 31a, GPS module 32a, tactile switches 32e to 32g, SD card slot component 33a, and electrostatic touch panel 41, performs various arithmetic operations, and outputs control signals to the built-in speaker 32c, FM transmitter 33c, and LCD display 34a. The radar module 31a also receives a microwave detection signal from the patch antenna 31c. The FM transmitter 33c is configured to transmit not only the music playback signal received from the microcomputer 50 but also the music playback signal received from the external input terminal receptacle component 33b. The music playback signal transmitted from the FM transmitter 33c is received by a car stereo 60 and output via an in-vehicle speaker 61.
[0070] In this embodiment, the audio output destination for speed enforcement information monitoring control can be selected to be the built-in speaker 32c or the in-vehicle speaker 61. This is achieved by setting the audio output destination to the FM transmitter 33c in the microcomputer 50. The microcomputer 50 also has a music playback program that reads and plays music data from an SD card inserted in the SD card slot component 33a. Music played by this music playback program can be heard on the in-vehicle speaker 61 via the FM transmitter 33c. Meanwhile, in this embodiment, music playback data can be input from a portable music player as an external input, and can be heard on the in-vehicle speaker 61 via the FM transmitter 33c. To achieve these controls, the following control programs are installed in the microcomputer 50.
[0071] As shown in FIG. 13A, when a command to switch the audio output destination is received from the touch panel 41 (S10), the microcomputer 50 switches the audio output destination to the FM transmitter 33c (S20). The default audio output destination is the built-in speaker 32c. Next, it is determined whether or not an input is being received from the external input terminal (S30). If an input is being received from the external input terminal (S30: YES), regardless of the audio output destination switching command received in S10, the audio output destination is forcibly returned to the built-in speaker 32c (S40). Then, when the audio notification timing arrives (S50: YES), audio is output at a predetermined volume (S60).
[0072] Also, as shown in FIG. 13(B), when push buttons 11 to 13 are operated (S110: YES), it is determined whether the operation is for song selection (S120). If it is for song selection (S120: YES), music information is read from the SD card inserted in the SD slot and displayed on the LCD display (S130). When a playback command is input (S140: YES), music is played (S150) and it is determined whether an alarm timing has arrived (S160). If an alarm timing has arrived (S160: YES), the volume is forcibly lowered (S170) regardless of the set volume and output to FM transmitter 33c (S180). If it is not an alarm timing, the set volume is output to the FM transmitter (S160: NO → S180). The determination of S160 is always made during MP3 playback (S180 → S60). This allows the driver to enjoy music through the in-vehicle speaker 61 without interfering with the notification voice based on the monitoring results of speed enforcement information.
[0073] As a result of the above control processing, the priority order is as shown in the upper table of Figure 13(C), with the alarm sound (RD) always taking top priority. The default condition is to set the built-in speaker (SP) as the alarm sound output destination, but when using MP3, the user can also set the FM transmitter (FMT) as the output destination. In this case, as mentioned above, the volume of the MP3 playback sound is lowered at the time of the alarm regardless of the volume setting, so it does not interfere with the alarm sound. Furthermore, when using an external input, the alarm sound (RD) is fixed to the built-in speaker (SP), so the alarm sound will not blend in with the music and become difficult to hear.
[0074] According to this embodiment, various settings can be made using the touch panel 41 on the front, even complex settings, with a natural feel. In addition, the music playback push buttons 11 to 13, which are likely to be operated frequently due to the MP3 playback function, are provided as dedicated buttons in the front half of the top surface of the main body case 2, making it easy to operate.
[0075] Next, various setting inputs using the electrostatic touch panel 41 will be described. As shown in FIG. 14, the electrostatic touch panel 41 is divided into three equal parts: a left sensor area 71, a central sensor area 72, and a right sensor area 73. The wiring can be configured, for example, as shown in FIG. 14(B), from independent wiring 71a to 73a from each of the sensor areas 71 to 73 and a common loop wiring 74 arranged to surround all of the sensor areas. With this configuration, when any of the sensor areas is touched with a finger, a change in capacitance occurs, making it possible to detect which sensor area has been touched.
[0076] An input method using electrostatic touch panel 41 with the sensor area divided into three will be described with reference to the flowcharts of Figures 15 to 20. This processing is performed by microcomputer 50 executing a program that has been installed in advance.
[0077] 15, in the touch operation determination routine, when a change in capacitance occurs in any of the three sensor areas 71-73 of the touch panel 41 (S210), it is determined whether the change in capacitance is due to an initial touch (S220). If it is determined to be an initial touch (S220: YES), the sensor area where the capacitance changed due to the finger touch is identified as touch position A and stored in memory together with the detection time (S225). If it is determined not to be an initial touch (S220: NO), it is determined whether or not a release has occurred (S230). If the result is "YES," the sensor area where the capacitance changed due to the finger being removed is identified as release position B and stored in memory together with the detection time (S235).
[0078] Next, it is determined whether both touch position A and release position B are stored in memory (S240). If both are stored (S240: YES), it is determined whether touch position A and release position B match (S250). If it is determined that they match (S250: YES), it is determined whether there was a long press (S260). Whether there was a long press can be determined, for example, from a predetermined long press determination time and the difference between the release position detection time and the touch position detection time. If it is determined that there was a long press (S260: YES), information specifying "touch position A and long press" is stored in memory as "touch panel operation information" (S270). On the other hand, if it is determined that there was not a long press (S260: NO), information specifying "touch position A and one touch" is stored in memory as touch panel operation information (S275).
[0079] On the other hand, if touch position A and release position B are different (S250: NO), it is determined whether release position B is in an area to the left of touch position A (S280). If the determination is "YES", a "left flick" is stored in memory as "touch operation information" (S290), and if the determination is "NO", a "right flick" is stored in memory as "touch operation information" (S295).
[0080] The microcomputer 50 executes the following process based on the touch operation information. This process is also executed according to a pre-installed program, and as shown in Fig. 16(A), it determines whether the current display state is the "standby screen" (S310), and if it is not the standby screen, it exits this routine and proceeds to S410.
[0081] If the standby screen is displayed (S310: YES), it is determined whether the touch operation information is a center one-touch (S320). If it is determined to be a center one-touch (S320: YES), the standby screen is switched to the next standby screen (S330). This standby screen switching is performed as shown in FIG. 16(B), by switching from "Radarscope" to "Clock" to "Speed" to "Eco-Driving" to "Positioning Information" to "OFF" to "Radarscope" to... and then to the rotary. Note that "Eco-Driving" is a standby screen that calculates and displays a comprehensive evaluation result of four items: sudden acceleration, sudden deceleration, idling time, and deviation from economical speed based on GPS speed data, and displays the score.
[0082] On the other hand, if it is determined that the touch was not a one-touch touch in the center (S320: NO), it is determined whether it was a long press or not (S340). If it is determined that the touch was a long press (S340: YES), it is determined whether the touch position at the time of the long press was left / center / right (S350). If it was a long press in the center (S350: center), the display of the "standby screen" is stopped and the display switches to the "setting mode icon screen" (S360). As shown in the center of Figure 17(C), the icon representing the setting mode is displayed in the center of the screen. At this time, the icon for the city map service is visible on the right side of the screen, about one-third of the way up.
[0083] If the left button is pressed and held (S350: left), the volume bar is superimposed and volume down processing is executed (S370). For example, the amount of volume down from the current volume setting is calculated based on the length of time the button is pressed and held, and processing is executed to update the volume setting. In this embodiment, if the command is to lower the volume setting below "zero," silent mode is set. An example of the screen display during volume down processing when the standby screen is a clock is shown on the left side of Figure 17(C). As shown, silent mode is entered at VOL0.
[0084] If the right button is pressed and held (S350: left), the volume bar is superimposed and volume-up processing is executed (S375). For example, the amount of volume increase from the current volume setting is calculated based on the length of time the button was pressed and held, and the volume setting is updated. If the phone is currently in silent mode, the silent mode is first canceled. The right side of Figure 17(C) shows an example of the screen display during volume-up processing when the standby screen is a clock. As shown, the volume increases to the maximum value VOL7 and then stops.
[0085] If S310 returns "NO," the routine shown in FIG. 17A is executed, and it is determined whether the current display state is the "setting mode icon screen" (S410). If it is the setting start screen (S410: YES), it is determined whether the touch operation was a center one-touch (S420). If it is determined "YES," the process proceeds to the setting item screen (S430). This allows conditions for various setting items to be set. On the other hand, if it is not a center one-touch (S420: NO), it is determined whether it is a left flick (S440). If it is determined "YES," the screen is scrolled to the left (S450). In this embodiment, scrolling this screen to the left brings the city map service screen to the center. Note that this routine is exited without any action being taken for touch operations other than the center one-touch and left scroll. Figure 17(B) shows how a single touch on the center of the setting mode icon takes you to the setting item screen, and Figure 17(c) shows how a left flick scrolls the screen from the setting mode icon to the city map icon.
[0086] If both S310 and S410 are judged "NO," the routine shown in FIG. 18A is executed to determine whether the current display state is the "setting item screen" (S510). If it is the setting item screen (S510: YES), it is determined whether the touch operation was a center one-touch (S520). If the determination is "YES," the center display is switched to the next setting condition screen for the current setting item (S530). On the other hand, if it is determined that it was a left scroll rather than a center one-touch (S520: NO, S540: YES), the screen is scrolled left to display the next setting item screen (S550). Conversely, if it is determined that it was a right flick (S520: NO, S540: NO, S560: YES), the screen is scrolled right to display the previous setting item screen (S570). The setting item screens are switched using a rotary, so that scrolling further left from the last setting item screen switches to the first setting item screen, and scrolling right from the first setting item screen switches to the last setting item screen. Figure 18(B) shows an example of how the setting item screens are switched by flicking left or right, and how a single touch in the center moves to the setting condition screen.
[0087] If S310, S410, and S510 are all determined to be "NO," the routine shown in FIG. 19A is executed to determine whether the current display state is the "setting condition screen" (S610). If it is the setting condition screen (S610: YES), it is determined whether the touch operation was a one-touch operation at the center (S620). If the determination is "YES," the setting conditions of the current setting item screen are advanced (S630). On the other hand, if it is determined that the touch operation was a long press at the center rather than a one-touch operation at the center (S620: NO, S640: YES), the content corresponding to the current screen display is set as the setting condition for that setting item (S650). If it is determined that the touch operation was a left flick rather than a one-touch operation at the center or a long press at the center (S620: NO, S640: NO, S660: YES), the screen is scrolled left to display the next setting item screen (S670). Conversely, if it is determined that the flick is to the right (S620: NO, S640: NO, S660: NO, S680: YES), the screen is scrolled to the right to display the previous setting item screen (S690). This setting item screen switching is performed using a rotary scroll. Figure 19(B) illustrates how the setting condition screen advances to the next setting condition screen with a single touch of the center, how the condition is set by pressing and holding the center, and how the setting item is switched by flicking left or right.
[0088] If the results of S310, S410, S510, and S610 are all "NO," the routine shown in FIG. 20(A) is executed, and it is determined whether the current display state is the "city map icon screen" (S710). If it is the city map icon screen (S710: YES), it is determined whether the touch operation was a center one-touch (S720). If the result is "YES," a two-dimensional barcode indicating the current location based on GPS positioning information is displayed (S730), as shown in FIG. 20(B). The user can receive a service that displays a map and information of the surrounding area on their mobile phone by reading and transmitting this two-dimensional barcode using the barcode reading function of their mobile phone. Note that touching again returns to the icon screen.
[0089] As shown in FIG. 21(A), the information display device 1 of this embodiment can set various conditions for various items. This condition setting can be performed according to the flow shown in FIG. 21(B), and the calculation process described with reference to FIGS. 15 to 20 is executed during this process. Note that the setting conditions marked with a star for each setting item in FIG. 21(A) are the initial values. By displaying and long-pressing the setting initialization icon, the settings can be returned to the initial settings marked with a star. Furthermore, as described above, the information display device 1 of this embodiment can play MP3 data, and as shown in FIG. 21(C), can display a music player screen as the standby screen.
[0090] As shown in Figure 22(A), this music player screen becomes the standby screen only when a microSD card is inserted in the SD card slot. Subfolders can be stored in the microSD card, and the standby screen displays the song title, artist name, album name, folder name, playback mode (repeat mode), and operation status (play icon), as well as the playback time, as shown in Figure 22(B). The operation status, as shown in Figures 22(C) and (D), can be set by pressing the push buttons 11 to 13 on the top of the device, to play, stop, fast-forward, skip to the next song, rewind, or go to the beginning of the song.
[0091] In this way, the information display device 1 of this embodiment divides the electrostatic touch panel 41 into thirds in the left-right direction, particularly into three equal parts to form the sensor area, so that it is possible to distinguish between touch methods that are ambiguous based on the user's intuition, such as those around the middle, left, and right, and to determine touch operations. Furthermore, by dividing the sensor area into three equal parts, it is possible to accurately and easily determine whether a flick operation has occurred based on whether the touch position and release position are aligned or not, without requiring the user to perform precise operations. It is also possible to clearly distinguish between a single touch and a long press based on the length of the touch time from touch to release.
[0092] For example, even if the device has a small external shape of less than 100mm square and the screen is only a few inches in size, it is divided into three equal parts: left, center, and right, so users will not find it difficult to touch the center or near the edges.
[0093] On the other hand, the standby screen uses the entire screen, while the settings screen is divided into sensor areas, allowing different screens to be used depending on their purpose. On the settings screen, icon images are displayed so that they fit within the central sensor area, while the icons for the next and previous settings are shifted to the outside, so that only about one-third of the screen is visible. Therefore, when scrolling to the next setting item, the user naturally touches near the right edge, making it easy to perform a reliable flick operation unconsciously. This gives the user the feeling of a smooth screen transition.
[0094] Also, the screen scrolling is done by flicking, and screen advancement to change setting conditions within the same setting item is done with one touch, so the operation feel and the way the screen changes are consistent. In addition, operations based on the user's clear intention, such as switching from the standby screen to the setting screen or confirming setting conditions on the setting screen, require a long press, which also matches the user's sense and the operation content.
[0095] Furthermore, in the device of the embodiment, since it is equipped with a music playback function, playback operations, which are likely to be performed frequently, are performed using dedicated push buttons 11 to 13 located in the front half area of the top surface of the main body case rather than touching the music player standby screen, making it easy to operate, and by displaying song information on the music player display on the standby screen, users can easily select their favorite songs.
[0096] According to this embodiment, in an in-vehicle electronic device that employs a touch panel input method, various inputs can be made without complexly setting the touch detection area, and a technology that can be applied to compact in-vehicle electronic devices can be provided. [Example]
[0097] Next, a manufacturing example of the main body case 2 will be described as Example 2. As shown in Figure 23, the dimensions are W = 56 mm, H = 54 mm, D = 53 mm, and the bulge of the side is 0.5 mm. The side is painted with a metallic look, while the other surfaces are matte painted. Furthermore, raised engraving is applied to the top of the SD card slot and external input terminal slot on the right side, and recessed engraving is applied to the narrowed portion to create a sheet metal look. Furthermore, symbols indicating the functions of the push buttons and the type of device are printed on the top surface. The main body case is an injection-molded synthetic resin product.
[0098] According to this manufacturing example, the "matt paint" gives a "solid feel" and a luxurious feel, and the "metallic look paint" gives a "solid impression" that the contents are well protected, while the "part of the side with the metallic look paint protrudes when viewed from the front" creates a "mechanical impression." In addition, the engraving on the right side, together with the metallic look paint, gives the impression of sheet metal, further enhancing the mechanical impression.
[0099] According to Example 1 and its manufacturing example (Example 2), when installed in a vehicle, for example, on the dashboard, the information can be viewed by the driver, and there is no hindrance to the performance of the original function, and an information display device that is attractive as interior décor in the vehicle can be provided.
[0100] And despite its small body measuring just 50mm square, various settings can be easily controlled by touching the touch panel.
[0101] Although the embodiments for carrying out the invention have been described above, the present invention is not limited to these, and various modifications are possible within the scope of the gist of the invention.
[0102] For example, the present invention can be applied to car navigation systems and other in-vehicle electronic devices. Also, when the alarm function is ON, the control content may be set to lower the volume of MP3 playback. [Industrial Applicability]
