Description

  The present invention relates to a display control device and a display control method for a meter panel with a movable mechanism, and particularly suitable for use in a display control device for a meter panel having a movable mechanism for physically moving a decorative member on the front surface of the display. It is.

  Conventionally, there is a vehicle in which a meter panel assembled to a dashboard is configured by a liquid crystal display. This type of meter panel includes not only meter information necessary for vehicle travel, such as travel speed, engine speed, and fuel level, but also information indicating the shift position and a warning light that lights when an important device fails. Etc. are displayed. There is also a meter panel in which information related to navigation devices and audio devices is displayed.

  Also, some recent meter panels have a movable mechanism in which a decorative ring is arranged on the front surface of a liquid crystal display and the decorative ring is physically moved in accordance with the display state of the liquid crystal display.

  For example, as shown in FIG. 4A, when the vehicle accessory switch (ACC) is off and the liquid crystal display 11 is not displayed, the two decorative rings 12 are overlapped on the center of the liquid crystal display 11. When the ACC is turned on and meter information or the like is displayed on the liquid crystal display 11, the two decorative rings 12 are moved so as to be divided into left and right as shown in FIG. Each of the decorative rings 12 is stopped at the positions of the two pieces of meter information displayed on both the left and right sides. When the ACC is switched from on to off, the decorative ring 12 moves in the reverse direction as shown in FIGS. 4 (c) → (b) → (a).

  However, in the meter panel having the movable mechanism as described above, when the movable mechanism becomes inoperable due to some trouble during the movement of the decorative ring 12, it may be displayed on the liquid crystal display 11 depending on the stop position of the decorative ring 12. There is a problem that the information on the meter panel is hidden by the decorative ring 12 and may not be visible. For example, if the decoration ring 12 stops at a position as shown in FIG. 4B, it becomes difficult to see a part of the meter information, shift position information, and warning light display.

  The display comprises a liquid crystal display, a substantial meter arranged in front of the display, and a moving mechanism for moving the substantial meter, and the substantial meter is moved from the first position to the second position, or There has also been proposed a vehicular display device that displays a speed on a display when an operation state of a moving mechanism becomes abnormal for some reason while moving from a second position to a first position ( For example, see Patent Document 1).

  In addition, a display is provided between two analog-type instruments (speedometer and tachometer), and either one of the two instruments is selected depending on whether the left half or right half of the display has a larger amount of data. A movable meter has been proposed in which the visibility of the display is improved by moving it diagonally rearward of the display (see, for example, Patent Document 2).

JP 2009-52923 A JP 2010-190606 A

  The technique described in Patent Document 1 is to display the speed on the display instead of the actual meter when the moving meter has failed due to some cause and the actual meter stops, thereby improving the visibility of the display. It is not a thing. On the other hand, the technique described in Patent Document 2 is intended to improve the visibility of the display, but moves the instrument in accordance with the amount of data in the left and right areas of the display. It is not a solution to the problem when it becomes impossible. Therefore, even if any technique of patent documents 1 and 2 is used, the problem that it becomes difficult to see the display on the display when the movable mechanism becomes inoperable during the movement of the decorative ring cannot be solved.

  The present invention has been made to solve such problems, and even when the movable mechanism becomes inoperable during the movement of the decorative member, the information on the meter panel can be easily displayed on the display. The purpose is to do.

In order to solve the above-described problems, in the present invention, when an abnormal stop of a movable mechanism that physically moves the decorative member on the front surface of the display is detected, the display that does not overlap the decorative member from the stop position of the decorative member Non-overlapping display position, which is the upper display position, is detected, and some of the information that is normally displayed on the display when there is no abnormal stop of the movable mechanism is displayed in a non-overlapping manner It is displayed at the position .

  According to the present invention configured as described above, even when the movable mechanism becomes inoperable during the movement of the decorative member, the information on the meter panel is displayed at a position on the display that does not overlap with the decorative member stopped at an unexpected position. Therefore, it is possible to avoid the inconvenience that the information is hidden by the decorative member and cannot be seen, and the information on the meter panel can be easily displayed on the display.

It is a figure which shows the structural example of the display system provided with the display control apparatus of the meter panel with a movable mechanism by this embodiment. It is a figure which shows the example of a display of a liquid crystal display at the time of abnormality occurrence of a movable mechanism. It is a flowchart which shows the operation example of the display control apparatus by this embodiment. It is a figure which shows the example of a movement of a decoration ring.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating a configuration example of a display system including a display control device for a meter panel with a movable mechanism according to the present embodiment. As shown in FIG. 1, the display system of this embodiment includes a meter panel 10 with a movable mechanism, and a display control device 20 that performs display control of information on a liquid crystal display 11 included in the meter panel 10. Yes.

  The meter panel 10 with a movable mechanism includes a liquid crystal display 11, two decorative rings 12 that physically move on the front surface of the liquid crystal display 11, and a drive unit 13 as a movable mechanism that moves the decorative ring 12. ing. The decoration ring 12 receives the drive signal from the drive unit 13 and operates in the same manner as shown in FIG.

  That is, when the vehicle ACC is off and the liquid crystal display 11 is not displayed, the two decorative rings 12 are overlapped on the center (standby position) of the liquid crystal display 11 as shown in FIG. When the ACC is turned on and meter information or the like is displayed on the liquid crystal display 11, the drive unit 13 outputs a drive signal, so that two decorative rings as shown in FIG. 4 (b) → (c). 12 is moved so as to be divided into left and right. Then, the decorative rings 12 are stopped at the positions (meter positions) of the two meter information displayed on the left and right sides of the liquid crystal display 11. At this time, the decoration ring 12 moves by a predetermined distance from the center of the liquid crystal display 11 toward the left and right sides each time a positive phase pulse is output once as a drive signal.

  After that, when the ACC is switched from on to off, the drive unit 13 outputs a drive signal composed of pulses having opposite phases, whereby the two decorative rings 12 are obtained as shown in FIG. 4 (c) → (b) → (a). Is moved from the meter position on both sides toward the center standby position. Then, the decorative rings 12 are overlapped and stopped at the standby position. At this time, the decoration ring 12 moves by a predetermined distance from the left and right sides of the liquid crystal display 11 toward the center every time a pulse having an opposite phase is output as a drive signal.

  The movable mechanism-equipped meter panel 10 includes a position sensor (not shown), and detects the position of the moving decoration ring 12 as needed, and sends the detected position information to the drive unit 13 as needed. For example, the position sensor of the meter panel 10 detects the phase of the pulse of the drive signal supplied from the drive unit 13 and counts the number of outputs, so that the decoration ring 12 is located on the left and right sides or both left and right sides from the center of the liquid crystal display 11. The amount of movement from the center to the center is grasped, and the current position of the decoration ring 12 is detected according to the amount of movement. The method for detecting the position of the decorative ring 12 described here is merely an example, and the present invention is not limited to this.

  The display control device 20 includes, as its functional configuration, a display information input unit 21, a normal display pattern data storage unit 22, an abnormal display pattern data storage unit 23, a display control unit 24, an abnormality detection unit 25, and a stop position detection unit 26. And a non-overlapping display position detector 27 is provided.

  Here, each function of the display information input unit 21, the display control unit 24, the abnormality detection unit 25, the stop position detection unit 26, and the non-superimposed display position detection unit 27 has a hardware configuration, a DSP (Digital Signal Processor), and software. Any of these can be realized. For example, when realized by software, each of the above functions is actually configured by including a computer CPU or MPU, RAM, ROM, and the like, and can be realized by operating a program stored in the RAM or ROM. The program may be stored in another recording medium such as a hard disk or a semiconductor memory.

  The display information input unit 21 inputs various display information through a CAN (Control Area Network) that is one of the in-vehicle networks. The display information input by the display information input unit 21 is output from, for example, meter information necessary for vehicle travel, such as travel speed and engine speed, information indicating a shift position, warning information for notifying important equipment failure, and a navigation device. Driving guidance information.

  The normal-time display pattern data storage unit 22 is data related to a display pattern when displaying the display information input by the display information input unit 21 on the liquid crystal display 11 when the movable mechanism of the meter panel 10 is operating normally. Is remembered. The state in which the display information is displayed according to the normal display pattern data is as shown in FIG.

  For example, regarding the meter information of the running speed and the engine speed, pattern data imitating a circular physical entity meter is stored in the normal display pattern data storage unit 22. That is, the pattern data is a pattern in which a plurality of numbers and scales are drawn along the circumference, and an indicator is drawn at a position corresponding to the traveling speed and engine speed input from the display information input unit 21. It is.

  Regarding the shift position information, the characters representing all the gear positions are drawn side by side, and the pattern data that is drawn with emphasis on the characters corresponding to the shift position input from the display information input unit 21 is normal. It is stored in the display pattern data storage unit 22.

  The warning information for notifying the failure of the important device is drawn with the warning lights representing the individual important devices arranged side by side, and the warning light corresponding to the warning information input from the display information input unit 21 is turned on. The pattern data thus made is stored in the normal display pattern data storage unit 22.

  As for the travel guide information, pattern data in which the travel guide information is drawn in a rectangular frame of a predetermined size is stored in the normal-time display pattern data storage unit 22. The pattern data for displaying the meter information, the shift position information, the warning information, and the travel guide information on the liquid crystal display 11 includes position / size information as to which position on the liquid crystal display 11 is to be displayed in which size.

  The abnormal-time display pattern data storage unit 23 is used when an abnormality occurs in the movable mechanism of the meter panel 10 and the decorative ring 12 stops at an unexpected position (a position that is neither the standby position nor the meter position). The display information input by the display information input unit 21 is stored with data relating to a display pattern when the liquid crystal display 11 is displayed. The display pattern data at the time of abnormality includes size information indicating which size the display information is displayed, but does not include position information indicating which position on the liquid crystal display 11 the display information is displayed. The state in which display information is displayed on the liquid crystal display 11 in accordance with the display pattern data at the time of abnormality will be described in detail later.

  The display control unit 24 has a movable mechanism for displaying display information input by the display information input unit 21 based on display pattern data stored in the normal display pattern data storage unit 22 or the abnormal display pattern data storage unit 23. It is displayed on the liquid crystal display 11 of the meter panel 10.

  The contents of the display control when the movable mechanism of the meter panel 10 is operating normally are as shown in FIG. That is, the display control unit 24 displays the meter information 41 and 42 of the running speed and the engine speed on both the left and right sides of the liquid crystal display 11 based on the normal display pattern data, and shift position information between both meters. 43, traveling guide information 44, and warning lamp 45 are displayed in order from the top. On the other hand, details of display control performed by the display control unit 24 when an abnormality occurs in the movable mechanism of the meter panel 10 will be described later in detail.

  The abnormality detection unit 25 detects that an abnormal stop has occurred in the movable mechanism of the meter panel 10. For example, the abnormality detection unit 25 detects that an abnormal stop of the movable mechanism has occurred when the return of position information is lost despite the drive unit 13 outputting a drive signal pulse. In addition, the abnormality detection unit 25 detects that an abnormal stop of the movable mechanism has occurred when there is no change in the returned position information no matter how many times the drive unit 13 outputs a drive signal pulse. .

  The stop position detection unit 26 detects the stop position of the decorative ring 12 when the abnormality detection unit 25 detects an abnormal stop of the movable mechanism. For example, when the abnormality detection unit 25 detects that the position information has not been returned even though the drive unit 13 has output the drive signal, at the position indicated by the position information sent immediately before the response is lost. It is determined that the decorative ring 12 has stopped. In addition, when the abnormality detection unit 25 detects that no change has occurred in the returned position information, no matter how many times the drive unit 13 outputs the drive signal, the position information indicated by the position information no longer changes is detected. It is determined that the decorative ring 12 has stopped.

  The non-superimposed display position detection unit 27 overlaps the decoration ring 12 based on the stop position of the decoration ring 12 detected by the stop position detection unit 26 when the abnormality detection unit 25 detects an abnormal stop of the movable mechanism. A non-overlapping display position that is a display position on the liquid crystal display 11 is detected. The non-superimposed display position detection unit 27 also detects a displayable area at the non-superimposed display position.

  For example, when the stop position detection unit 26 detects that the decoration ring 12 has stopped at the position shown in FIG. 4B, the non-overlapping display position and the displayable area that do not overlap with the decoration ring 12 at the stop position. Is detected. Since the size of the liquid crystal display 11 and the size and shape of the decoration ring 12 are known, the non-overlapping display position and the displayable area on the liquid crystal display 11 can be detected as long as the stop position of the decoration ring 12 is known.

  When the abnormality detecting unit 25 detects an abnormal stop of the movable mechanism, the above-described display control unit 24 detects an abnormality with respect to the displayable area of the non-superimposed display position detected by the non-superimposed display position detection unit 27. Based on the display pattern data at the time of abnormality stored in the hour display pattern data storage unit 23, control is performed to display various display information input by the display information input unit 21.

  In the present embodiment, the display control unit 24 non-superimposes a part of predetermined display information among a plurality of display information normally displayed on the liquid crystal display 11 when the abnormal stop of the movable mechanism has not occurred. Control to display at the display position. That is, which information is displayed as a part of display information is stored in the abnormal-time display pattern data storage unit 23 as abnormal-time display pattern data.

  Some pieces of information that the display control unit 24 displays at the non-overlapping display position when an abnormality occurs in the movable mechanism are travel speed information, shift position information, and warning lamp information. This is because these pieces of information are particularly important for driving safety. On the other hand, the information on the engine speed and the travel guide information are not displayed on the liquid crystal display 11 when an abnormality occurs in the movable mechanism.

  In addition, the display control unit 24 does not display the display information in the form normally displayed on the liquid crystal display 11 when the movable mechanism has not stopped abnormally, but displays the display information by changing the display form of the display information. To control. The display mode in which the display information is displayed is also stored in the abnormal-time display pattern data storage unit 23 as display pattern data at the time of abnormality.

  FIG. 2 is a diagram illustrating a display example of the liquid crystal display 11 when an abnormality occurs in the movable mechanism. When the decorative ring 12 abnormally stops at the position shown in FIG. 2, the display control unit 24 moves the moving speed information, the shift position information, and the warning light information within the displayable area of the non-superimposed display position. When the abnormal stop is not generated, the display is performed in a mode different from the mode normally displayed on the liquid crystal display 11.

  Specifically, the travel speed information is controlled so as to be displayed only as the number 51 of the corresponding speed indicated by the travel speed information input by the display information input unit 21, not in a form simulating a circular substantial meter. To do. Further, the shift position information is controlled to be displayed only as the character 52 of the corresponding position indicated by the shift position information input by the display information input unit 21. The warning light information is controlled to be displayed only as the warning light 53 of the corresponding warning indicated by the warning information input by the display information input unit 21.

  Where the travel speed information 51, the shift position information 52, and the warning light information 53 are displayed on the liquid crystal display 11, the size of each display information indicated by the display pattern data at the time of abnormality, and the non-overlapping display position The display control unit 24 determines based on the displayable area at the non-overlapping display position detected by the detection unit 27. That is, the display control unit 24 displays each display information at a position where the size indicated by the display pattern data at the time of abnormality falls within the displayable area. Any display position can be used as long as it is within the displayable area. For example, each display information is displayed in preference to the four corner positions of the liquid crystal display 11.

  Here, the display control unit 24 displays the display information when the displayable area is small and the display information cannot be displayed in the size corresponding to the display pattern data at the time of abnormality within the displayable area. The display may be reduced to fit within the possible area.

  FIG. 3 is a flowchart showing an operation example of the display control apparatus 20 according to the present embodiment configured as described above. The flowchart shown in FIG. 3 starts when ACC is turned on. When ACC is turned off, the display on the liquid crystal display 11 is completely erased, so display control by the display control device 20 is unnecessary.

  When the ACC is turned on, the display control unit 24 first displays the display information input by the display information input unit 21 based on the normal display pattern data stored in the normal display pattern data storage unit 22. It is displayed on the liquid crystal display 11 (step S1).

  Next, the abnormality detection unit 25 determines whether or not an abnormal stop of the movable mechanism has occurred (step S2). Here, when the occurrence of abnormality of the movable mechanism is not detected, the stop position detection unit 26 determines whether or not the decoration ring 12 has reached the meter position (step S3).

  When the stop position detection unit 26 detects that the decoration ring 12 has reached the meter position, the process of the flowchart shown in FIG. 3 ends. On the other hand, if the decorative ring 12 has not yet reached the meter position, the process returns to step S2. If the occurrence of an abnormality in the movable mechanism is detected in step S2, the stop position detection unit 26 detects the stop position of the decorative ring 12 (step S4).

  Subsequently, the non-superimposed display position detecting unit 27 is a non-superimposed display position that is a display position on the liquid crystal display 11 that does not overlap with the decorative ring 12 based on the stop position of the decorative ring 12 detected by the stop position detecting unit 26. Is detected (step S5). Then, the display control unit 24 switches the normal display pattern to the abnormal display pattern, and causes the liquid crystal display 11 to display a part of the display information input by the display information input unit 21 (step S6).

  That is, the display control unit 24 displays the non-superimposed display position detected by the non-superimposed display position detection unit 27 based on the display pattern data at the time of abnormality stored in the abnormal-time display pattern data storage unit 23. Control to display a part of the information. Thereby, the process of the flowchart shown in FIG. 3 is completed.

  As described above in detail, in this embodiment, when an abnormal stop of the movable mechanism that physically moves the decoration ring 12 is detected on the front surface of the liquid crystal display 11, the decoration ring 12 is moved from the stop position of the decoration ring 12. A non-superimposed display position that is a display position on the liquid crystal display 11 that is not superimposed is detected, and a part of the display information is displayed at the non-superimposed display position.

  According to the present embodiment configured as described above, even when the movable mechanism becomes inoperable during the movement of the decoration ring 12, the position on the liquid crystal display 11 does not overlap with the decoration ring 12 stopped at an unexpected position. Since the information on the meter panel is displayed, it is possible to avoid the inconvenience that the information is hidden by the decorative ring 12 and cannot be seen, and the information on the meter panel can be displayed on the liquid crystal display 11 in an easy-to-understand manner.

  In the present embodiment, among the various types of display information displayed when the movable mechanism is normal, only a part of the display information that is important for traveling safety is displayed at the non-overlapping display position. Further, in the present embodiment, a part of the display information is displayed at the non-overlapping display position instead of the mode displayed when the movable mechanism is normal, instead of the simplified mode dedicated to the time of abnormality. Thereby, even when the displayable area of the non-superimposed display position cannot be increased because the decoration ring 12 stops at an unexpected position, important display information can be displayed on the liquid crystal display 11 in an easily understandable manner.

  In addition, although the said embodiment demonstrated the example which uses the liquid crystal display 11 for the meter panel 10 with a movable mechanism, this invention is not limited to this. Any other display such as an organic EL display or a plasma display may be used as long as it can control the display of information as electronic processing.

  Moreover, although the said embodiment demonstrated the example using the circular decoration ring 12 as an example of a decoration member, this invention is not limited to this. As long as it is a decorative member that moves in front of the display, the shape and size are not particularly limited.

  In the above embodiment, the example in which the decoration ring 12 moves as shown in FIG. 4 when the ACC is turned on or off has been described. However, the timing at which the decoration ring 12 starts to move and the movement method are described in this example. It is not limited.

  In the above embodiment, the display information displayed by the display control unit 24 at the non-superimposed display position has been described by taking three examples of travel speed information, shift position information, and warning light information. The invention is not limited to this. At least one of these three pieces of information may be used, or other information may be used.

  Moreover, although the said embodiment demonstrated the example which displays display information according to the simplified display pattern at the time of abnormality when a movable mechanism generate | occur | produces, this invention is not limited to this. For example, when the display information can be displayed within the displayable area of the non-superimposed display position according to the normal display pattern that is not simplified, the display control unit 24 displays the display information according to the normal display pattern. It may be.

  Further, in the above embodiment, when the display information cannot be displayed in the size corresponding to the pattern data at the time of abnormality within the displayable area at the non-overlapping display position, the display information is reduced so as to be within the displayable area. However, the present invention is not limited to this. For example, the display information at the time of abnormality stored in the display pattern data storage unit 23 at the time of abnormality is not provided with size information, but is adjusted to a size that fits within the displayable area of the non-superimposed display position and the display information is displayed. You may do it.

  Alternatively, the following may be performed. That is, the display control unit 24 displays the display information according to the normal display pattern when the display information can be displayed within the displayable area of the non-superimposed display position according to the normal display pattern that is not simplified. On the other hand, if this is not possible, display information that is displayed in the normal mode when it is normal can be reduced to fit within the displayable area, or display information can be displayed according to a simplified display pattern that is exclusively for abnormal use. Is displayed within the displayable area of the non-overlapping display position.

  In the above-described embodiment, the example in which the non-superimposed display position is detected outside the decorative ring 12 has been described. However, the non-superimposed display position may be detected inside the decorative ring 12.

  In addition, each of the above-described embodiments is merely an example of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed in a limited manner. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
