Description

  The present invention relates to an analog meter mounted on a vehicle such as an automobile, and relates to a display unit driving method for a movable meter capable of moving a display unit.

  Analog vehicle meters mounted on vehicles such as automobiles include a speed meter that displays speed and a tachometer that displays engine speed. Various ideas for improving the visibility have been proposed for the display unit including these instruments. For example, a meter system (for example, refer to Patent Document 1) that rotates the dial of a speed meter to intuitively understand the arrival status of a pointer with respect to a speed limit, and two instruments are moved left and right to There is a combination instrument (see, for example, Patent Document 2) that allows another information to be displayed between instruments.

  Although it is the same that different information is displayed between the instruments, research is also being conducted on a movable meter in which two instruments are moved diagonally forward or diagonally backward. FIG. 9 and FIG. 10 are schematic diagrams showing how the conventional movable meter operates. As shown in FIG. 9, in this movable meter, the dials 22 and 32 of the two instruments (speedometer 20 and tachometer 30) are usually moved obliquely forward from the screen of the central display 50, Part of the left and right sides of the display 50 is covered (hereinafter referred to as an overlap region). At this time, on the display 50, only the minimum necessary information is displayed in the visible area.

  On the other hand, as shown in FIG. 10, when special information such as an emergency needs to be displayed largely, the dials of the two instruments move diagonally backward simultaneously, the overlap area disappears, and the display The entire 50 display becomes visible. Thus, since the instrument and the dial face move diagonally forward or diagonally backward, the viewing angle required for visual recognition of the display is smaller than when the instrument moves left and right as in the combination instrument disclosed in Patent Document 2. The display can be changed without spreading, and thus without reducing the driver's visibility.

  However, the movable meter described above has a problem that flexible display control cannot be performed because the two meters are uniformly moved obliquely rearward when performing special display on the display.

  For example, when a display prompting a right turn is displayed on the display, information is mainly displayed on the right half of the screen, so that it is not necessary to move backward to the instrument arranged on the left side of the display. Similarly, when the puncture of the left front wheel of the vehicle is notified, information is mainly displayed on the left half of the screen, and therefore, it is not necessary to move backward to the instrument arranged on the right side of the display. This is because the display of information presented to the driver is easier to visually recognize when concentrated in the center as much as possible.

  The present invention has been made in view of the above-described circumstances, and its purpose is to display the display by moving the instruments arranged on the left and right sides of the display independently and obliquely rearward in accordance with the display contents of the display. It is an object of the present invention to provide a method for driving a display unit of a movable meter that allows a driver to recognize whether the information to be performed is information related to the vehicle or to the left and right in the traveling direction, and can perform information display with high visibility.

Accordingly, a necessary display area is secured, and the driver can recognize whether the displayed information is information related to the vehicle or the right and left of the traveling direction, and information display with high visibility can be performed.
According to the display unit driving method of the movable meter having the configuration (2), the left and right overlap areas are eliminated and the display area is secured only when necessary. As a result, it is possible to make the driver recognize whether the displayed information is information related to the vehicle or the right and left in the traveling direction, and display information with high visibility.

In order to achieve the above-described object, the movable meter display unit driving method according to the present invention is characterized by the following (3).

Having

  According to the driving method of the movable meter having the configuration of (3) above, only one of the instruments moves diagonally backward based on the data on the left side or the right side included in the information displayed on the display, and overlaps. The area is eliminated. Accordingly, a necessary display area is secured, and the driver can recognize whether the displayed information is information related to the vehicle or the right and left of the traveling direction, and information display with high visibility can be performed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing a system configuration of a movable meter according to an embodiment of the present invention. The movable meter system 100 mainly includes a CPU 10, a speedometer 20, a tachometer 30, a graphic controller 40, a liquid crystal display (LCD) 50, a vehicle data input / output interface 60, an EEPROM 70, and the like.

  The CPU 10 is a control unit that controls the overall operation of the movable analog meter and the display, and the display unit driving method described later is realized by executing a program read into the CPU 10.

  The speedometer 20 is one of movable meters, and can be moved diagonally forward or diagonally backward by a speedometer moving motor 21. The tachometer 30 is also a movable meter, and can be moved diagonally forward or rearward by a tachometer moving motor 31. Note that the standard position of the two instruments (speedometer 20 and tachometer 30) is diagonally forward of the screen of LCD 50, and an overlap region occurs (normal time).

  The graphic controller 40 is a control unit for converting the generated or acquired image data into RGB image data that can be displayed on the LCD 50, and sending it to the LCD 50. The image data stored in the frame memory 41 is sent to the X driver 51 of the LCD 50 one screen at a time.

  The LCD 50 is a display disposed between two movable meters, and further includes a display unit including an X driver 51, a Y driver 52, an LCD power source 53, and the like. The RGB image data sent to the X driver 51 is displayed on the LCD 50 while being synchronized with the horizontal synchronizing signal sent to the X driver 51 and the vertical synchronizing signal sent to the Y driver 52.

  The vehicle data input / output interface 60 is an interface unit for acquiring measurement data from an external speed sensor or rotation speed sensor (both not shown). The indicated values of the pointers of the speedometer 20 and the tachometer 30 are determined based on data acquired through this interface. Further, LCD display-related data such as image information related to the traveling direction output from the navigation system (not shown) and notification information related to the vehicle such as tire punctures and failure points are also acquired via this interface.

  The EEPROM 70 is a rewritable memory for storing a program and data to be executed by the CPU 10, and an execution program for a display unit driving method described later is also stored here.

  Next, the operation of the movable meter configured as described above will be described.

  First, FIG. 2 is a flowchart showing a display operation procedure of the movable meter in the embodiment of the present invention. When the CPU 10 reads information relating to the vehicle or the traveling direction or the like via the vehicle data input / output interface 60 (step S10), the CPU 10 reads the analog instrument pointers of the speedometer 20 and the tachometer 30 according to the read instruction values. (Step S11).

  Next, the CPU 10 performs display processing of information displayed on the LCD 50 with the read information (step S12), and simultaneously performs display unit drive processing of the speedometer 20 and the tachometer 30 (step S13). The display unit driving process will be described later. The above is a series of display operation procedures.

[Embodiment 1]
FIG. 3 is a flowchart showing the display unit driving operation procedure of the movable meter according to the first embodiment of the present invention.

  First, the CPU 10 reads target image data to be sent from the graphic controller 40 to the X driver 51 (step S20), and divides the data amount into a left half and a right half of the screen (step S21).

  Next, the CPU 10 determines whether or not | A |> B by setting the right side data amount−the left side data amount = A in order to compare the data amount of the divided left and right data (step S22). (Step S23). Here, B is a predetermined set value, which means that the display unit driving operation is executed only when the difference between the left and right data amounts exceeds the predetermined value. That is, if | A |> B is not satisfied (No in step S23), the process ends without executing the display unit driving operation.

  FIG. 5 is a schematic diagram illustrating a display state of the movable meter before the display unit driving operation is performed. The dials 22 and 32 of the speedometer 20 and the tachometer 30 are moved diagonally forward of the screen of the LCD 50, and overlap areas are generated on both the left and right sides of the screen.

  Returning to the flowchart of FIG. 3, if the difference between the left and right data amounts exceeds a predetermined value (Yes in step S23) and A> 0 (Yes in step S24), the difference is displayed on the right half of the LCD 50. Therefore, the CPU 10 drives the tachometer moving motor 31 to move the tachometer 30 backward (step S25). Thereby, the overlap area on the right side of the screen of the LCD 50 is eliminated, and a large display area is secured on the right side of the screen. Here, the entire overlap area located on the right side of the screen of the LCD 50 is eliminated and a large display area is secured on the right side of the screen, but the rotation amount of the tachometer moving motor 31 is controlled to control the rotation amount. Even in a form in which a part of the overlap region is eliminated, it contributes to enlargement of the display region as compared with the conventional case.

  FIG. 6 is a schematic diagram illustrating a display state in which the tachometer 30 is moved obliquely rearward by the display unit driving process. The dial 22 of the speedometer 20 is left as it is, and only the dial 32 of the tachometer 30 is retracted to substantially the same plane as the screen of the LCD 50, and the overlap area on the right side of the screen is eliminated. Therefore, a guidance display that prompts a right turn in the traveling direction can be displayed largely on the right side of the screen.

  Returning to the flowchart of FIG. 3, after a predetermined time elapses (for example, after the right-turn screen display in FIG. 6 is erased), the CPU 10 drives the tachometer moving motor 31 to move the tachometer 30 forward. (Step S26). Thereby, the dial 32 of the tachometer 30 moves again to the center side (return to the initial position), and an overlap area is generated on the right side of the LCD 50 screen.

  On the other hand, if the difference between the left and right data amounts exceeds the predetermined value (Yes in step S23) and A> 0 is not satisfied (No in step S24), it is determined that there is a lot of data displayed on the left half of the LCD 50. Therefore, the CPU 10 drives the speedometer moving motor 21 to move the speedometer 20 backward (step S27). Thereby, the overlap area on the left side of the screen of the LCD 50 is eliminated, and a large display area is secured on the left side of the screen. Here, the entire overlap area located on the left side of the screen of the LCD 50 is eliminated and a large display area is secured on the left side of the screen. However, the rotation amount of the speedometer moving motor 21 is controlled to Even in a form in which a part of the overlap region is eliminated, it contributes to enlargement of the display region as compared with the conventional case.

  FIG. 7 is a schematic diagram illustrating a display state in which the speedometer 20 is moved obliquely rearward by the display unit driving process. The dial 32 of the tachometer 30 is left as it is, and only the dial 22 of the speedometer 20 is retracted to substantially the same plane as the screen of the LCD 50, and the overlap area on the left side of the screen is eliminated. Therefore, it is possible to display a guidance display for notifying the puncture (abnormality) of the vehicle left front wheel on the left side of the screen.

  Returning to the flowchart of FIG. 3, after a predetermined time has elapsed (for example, after the screen display for notifying abnormality in FIG. 7 is deleted), the CPU 10 drives the speedometer moving motor 21 to move the speedometer 20 forward. Move (step S28). As a result, the dial 22 of the speedometer 20 moves again to the center side (return to the initial position), and an overlap area is generated on the left side of the LCD 50 screen.

  The display unit driving operation is executed by the above procedure. The display area on the left or right side of the screen is enlarged only when necessary, so that the driver can also display information related to the vehicle or to the left or right of the traveling direction, for example, the brake failure location, punctured tire, head It is possible to appropriately recognize a failure point of a light, a left turn, a right turn, etc., and display information with high visibility.

[Embodiment 2]
Next, FIG. 4 is a flowchart showing the display unit driving operation procedure of the movable meter according to the second embodiment of the present invention.

  First, the CPU 10 receives image information related to a traveling direction output from a navigation system (not shown), a tire puncture or failure location, a headlight failure location, a left turn, a right turn, or the like via a vehicle data input / output interface 60. The LCD display related data such as the notification information including the left and right concepts regarding the traveling direction of the vehicle is read (step S30). For example, as shown in FIG. 8, the LCD display-related data is information regarding whether the data is display data mainly occupying the left side of the screen of the LCD 50 or display data mainly occupying the right side of the screen. Bit information is held at a predetermined position. Therefore, by analyzing the data, it is possible to determine which of the left and right overlap areas of the LCD 50 should be performed so as to eliminate the entire overlap area or a part thereof.

  The CPU 10 determines whether or not the read data is target data for an operation of moving the tachometer 30 obliquely backward (that is, display data mainly occupying the right side of the screen) (step S31). If the target data is for moving the tachometer 30 obliquely rearward (Yes in step S31), it is determined that there is a lot of data displayed on the right half of the LCD 50, so the CPU 10 turns the tachometer moving motor 31 off. The tachometer 30 is driven to move the tachometer 30 backward (step S32). Thereby, the overlap area on the right side of the screen of the LCD 50 is eliminated, and a large display area is secured on the right side of the screen. Here, the entire overlap area located on the right side of the screen of the LCD 50 is eliminated and a large display area is secured on the right side of the screen, but the rotation amount of the tachometer moving motor 31 is controlled to control the rotation amount. Even in a form in which a part of the overlap region is eliminated, it contributes to enlargement of the display region as compared with the conventional case.

  On the other hand, when the data is not the target data for the operation of moving the tachometer 30 obliquely rearward (No in step S31), the CPU 10 determines that the read data is the target data for the operation of moving the speedometer 20 obliquely rearward (that is, the left side of the screen). (Display data mainly occupied) is determined (step S33). If the target data is an operation data for moving the speedometer 20 obliquely backward (Yes in step S33), it is determined that there is a lot of data displayed on the left half of the LCD 50. Driven to move the speedometer 20 backward (step S34). Thereby, the overlap area on the left side of the screen of the LCD 50 is eliminated, and a large display area is secured on the left side of the screen. Here, the entire overlap area located on the left side of the screen of the LCD 50 is eliminated and a large display area is secured on the left side of the screen. However, the rotation amount of the speedometer moving motor 21 is controlled to Even in a form in which a part of the overlap region is eliminated, it contributes to enlargement of the display region as compared with the conventional case. On the other hand, if the target data is not the operation data for moving the speedometer 20 obliquely backward (No in step S33), the CPU 10 ends the process without executing the display unit driving operation.

  The display unit driving operation is executed by the above procedure. Since the display area on the left or right side of the screen is enlarged only when necessary, the driver can also appropriately recognize whether the displayed information is information related to the vehicle or the left and right of the traveling direction, Information display with high visibility can be performed.

  In the above embodiment, the description has been made using a speedometer and a tachometer as an example of the movable meter. However, the present invention is not limited thereto, and is an analog type and can be driven obliquely forward or obliquely backward. Any indicating instrument may be used as long as the movable meter has a possible configuration.

  As described above in detail, according to the display unit driving method of the movable meter of the present invention, the driver appropriately recognizes whether the displayed information is information related to the vehicle or the left and right of the traveling direction. It is possible to display information with high visibility.

  The display unit driving method of the movable meter according to the present invention has an effect that the driver can appropriately recognize whether the displayed information is information related to the vehicle or the right and left of the traveling direction. It is useful as an information display with high visibility.
