  FIG. 5 is a front view showing the completion of the start of the display 32 from the initial display 31 in the display 3 shown in FIG.

  The combination meter 1 that is a display device is arranged in front of the driver's seat of the automobile and displays various information related to the automobile.

  As shown in FIG. 1, the combination meter 1 according to the first embodiment includes a speedometer 2 that displays the traveling speed of the automobile and a liquid crystal panel 3 that is a single display that displays a plurality of information.

  The speedometer 2 includes a dial 21, a pointer 22 that rotates on the front surface thereof, and a movement 23 (FIG. 3) that is disposed behind the dial 21 and rotates the pointer 22. The movement 23 is composed of, for example, a cross coil actuator, a stepping motor, or the like, and rotates the pointer 22 by an angle corresponding to an external electric signal (vehicle speed signal).

  The liquid crystal panel 3 has a plurality of pieces of information with different starting points at which display can be started, the engine speed (Tacho) of the car, the travel distance (Odo), the time (Clock) of the car, and the engine coolant temperature ( Temp) and the fuel remaining amount (Fuel) of the vehicle. The engine speed, the coolant temperature of the engine, and the remaining amount of fuel are displayed by a digital bar, and the travel distance and time are displayed by numbers.

  The liquid crystal panel 3 is disposed in an opening provided in the design plate 8 for hiding each end of the dial 21.

  The liquid crystal panel 3 is formed with dot segments for displaying an engine speed (Tacho), an initial display 31 (FIG. 5) described later, and the like. As the liquid crystal panel 3 in the present embodiment, a liquid crystal panel that is translucent when no voltage is applied and is light-shielding when a voltage is applied is used. That is, when no voltage is applied, the whole is translucent, and when a voltage is applied, a predetermined dot segment is black, and a predetermined digital bar and characters (numbers) are displayed.

  FIG. 1 shows a state in which a voltage is applied to a predetermined dot segment to display all of a plurality of pieces of information such as the engine speed (Tacho).

  As shown in FIG. 2, a light-emitting diode 5 that transmits and illuminates the light-emitting diode 5 and a light diffusion plate 4 that diffuses light emitted from the light-emitting diode 5 and uniformly transmits and illuminates the liquid-crystal panel 3 are disposed behind the liquid-crystal panel 3. Is done. The reflector 9 guides light emitted from the light emitting diode 5 to the light diffusion plate 4.

  The movement 23 and the light emitting diode 5 described above are mounted on the printed circuit board 10, and the liquid crystal panel 3 is connected to the printed circuit board 10 by wiring (not shown). Further, a control device 11 (FIG. 3) for driving the movement 23, controlling the liquid crystal panel 3, and turning on / off the light emitting diode 5 is mounted on the printed circuit board 10.

  The electric circuit configuration of the combination meter 1 according to the first embodiment described above will be described with reference to FIG.

  The control device 11 is always supplied with electric power from a battery 17, and an ignition switch (I / G) 16 that is a power switch is connected so as to be able to detect its operation position (off position, on position). A speed sensor 12 for detecting the vehicle temperature, a water temperature sensor 13 for detecting the coolant temperature of the engine of the automobile, and a fuel level sensor 14 for detecting the remaining amount of fuel of the automobile are connected so that these detection signals can be input.

  The rotation sensor 15a for detecting the engine speed is connected to the control device 11 via an engine control device (E / G ECU) 15 so that these detection signals can be input. In addition, the movement 23, the liquid crystal panel 3, and the light emitting diode 5 that are driven by the control device 11 according to the detection signal from the vehicle speed sensor 12 are also connected to the control device 11.

  The control device 11 includes a microcomputer 11a, a power supply circuit 11d, an analog / digital converter (A / D converter) 11e, a serial communication integrated circuit (communication IC) 11f as serial communication means, and the like. The microcomputer 11a includes a central processor unit (CPU) 11b which is a control means, a memory 11c which is a storage means, and the like.

  Electric power is supplied from the battery 17 to the microcomputer 11a, the movement 23, the liquid crystal panel 3, and the light emitting diode 5 through the power supply circuit 11d. Detection signals from the speed sensor 12, the water temperature sensor 13, and the fuel level sensor 14 are taken into the CPU 11b via the A / D converter 11e. The detection signal of the rotation sensor 15a is taken into the CPU 11b via the E / G ECU 15 and the communication IC 11f.

  The A / D converter 11e converts each analog detection signal of the speed sensor 12 or the like into a digital signal, and the communication IC 11f receives a plurality of information signals and transmits them to the CPU 11b by using fewer signal lines. Communication control is performed.

  The CPU 11b controls the movement 23, the liquid crystal panel 3, the light emitting diode 5 and the like based on these signals and the like.

  The CPU 11b calculates the travel distance based on the speed signal from the speed sensor 12, and counts the time even when the ignition switch 16 is off.

  The remaining amount of fuel is information that is taken into the CPU 11b as the control means and requires a predetermined calculation process. That is, the CPU 11b calculates the remaining amount of fuel by performing an averaging process (calculation process for a certain period) that is a predetermined calculation process on the fuel level signal from the fuel level sensor 14.

  The display on the liquid crystal panel 3 is controlled by the CPU 11b based on the time information counted by the CPU 11b itself and the detection signals from the vehicle speed sensor 12, the water temperature sensor 13, the fuel level sensor 14, and the rotation sensor 15a.

  The memory 11c includes an electrically rewritable non-volatile memory or a backup RAM (random access memory) that stores the operation of the CPU 11b as a program, and accumulates data on the travel distance calculated by the CPU 11b.

  The CPU 11b counts the time even when the ignition switch (I / G) 16 is turned off. For this reason, the time (Clock) is determined when the ignition switch 16 is both on and off (ON / OFF), as shown in FIG. 4B. That is, the liquid crystal panel 3 can start displaying the time at the same time as the ignition switch 16 is turned on. That is, the start point at which the display can be started is at the same time as the ignition switch 16 is turned on.

  The memory 11c accumulates data on the travel distance (Odo) calculated by the CPU 11b even when the ignition switch 16 is off. For this reason, after the ignition switch 16 is turned on, the CPU 11b fetches the accumulated travel distance data from the memory 11c and displays it on the liquid crystal panel 3.

  Thereby, the display of the travel distance is delayed from the display of the time by the amount that the CPU 11b fetches the travel distance data from the memory 11c. As a result, the travel distance (Odo) is determined after an indefinite state (for example, 100 milliseconds (mS)) after the ignition switch 16 is turned on, as shown in FIG. 4C. That is, the liquid crystal panel 3 can start displaying the travel distance after a predetermined time (100 mS) after the ignition switch 16 is turned on. That is, the start time point at which display can be started is 100 ms after the ignition switch 16 is turned on.

  The detection signal of the water temperature sensor 13 is taken into the CPU 11b via the A / D converter 11e after the ignition switch 16 is turned on. The CPU 11 b displays information on the detection signal of the water temperature sensor 13 on the liquid crystal panel 3.

  As a result, the engine coolant temperature display indicates that the coolant temperature sensor 13 detects the engine coolant temperature and outputs a detection signal to the A / D converter 11e, and the A / D converter 11e outputs this signal. There is a delay from the display of the travel distance by the amount of A / D conversion. As a result, the coolant temperature (Temp) of the engine becomes indefinite for a longer time (for example, 200 mS) than the travel distance (Odo) after the ignition switch 16 is turned on, as shown in FIG. 4 (d). Confirmed.

  That is, the liquid crystal panel 3 can start displaying the engine coolant temperature after a predetermined time (200 mS) from when the ignition switch 16 is turned on. That is, the start time point at which the display can be started is 200 mS after the ignition switch 16 is turned on.

  The detection signal of the rotation sensor 15a is taken into the CPU 11b via the E / G ECU 15 and the communication IC 11f after the ignition switch 16 is turned on. The CPU 11b displays information on the detection signal of the rotation sensor 15a on the liquid crystal panel 3.

  Thereby, the display of the engine speed is delayed from the display of the coolant temperature of the engine by the amount of serial communication control by the communication IC 11f. As a result, as shown in FIG. 4E, the engine speed (Tacho) is in an indefinite state for a longer time (for example, 300 mS) than the engine coolant temperature (Temp) after the ignition switch 16 is turned on. Will be finalized.

  That is, the liquid crystal panel 3 can start displaying the engine speed after a predetermined time (300 mS) after the ignition switch 16 is turned on. That is, the start time point at which the display can be started is 300 mS after the ignition switch 16 is turned on.

  The detection signal of the fuel level sensor 14 is taken into the CPU 11b via the A / D converter 11e after the ignition switch 16 is turned on. The CPU 11b calculates the remaining amount of fuel by averaging the data of the A / D conversion words taken for a certain period (calculation process for a certain period). The CPU 11b displays information on the calculated remaining fuel amount on the liquid crystal panel 3.

  Thereby, the display of the remaining amount of fuel is delayed from the display of the coolant temperature of the engine by the amount that the CPU 11b performs the averaging process (calculation process for a certain period). Also, since the averaging processing time by the CPU 11b is longer than the serial communication control time by the communication IC 11f, the display of the remaining amount of fuel is delayed from the display of the engine speed by this difference.

  As a result, as shown in FIG. 4E, the remaining amount of fuel (Fuel) is longer than both the engine coolant temperature (Temp) and the engine speed (Tacho) after the ignition switch 16 is turned on. It is determined after the time (for example, 800 mS) becomes indefinite. That is, the liquid crystal panel 3 can start displaying the engine speed after a predetermined time (800 mS) after the ignition switch 16 is turned on. That is, the start time point at which the display can be started is 800 mS after the ignition switch 16 is turned on.

  As described above, the earliest information having the earliest start point, that is, the information that can be displayed earliest by the liquid crystal panel 3 is “time”. The plurality of pieces of information displayed on the liquid crystal panel 3 are “time”, “travel distance”, “cooling water temperature”, “rotation speed”, and “remaining amount of fuel” in order of earlier display start time.

  As shown in FIG. 1, the liquid crystal panel 3 displays the “time” of the earliest information at the center in the vertical direction indicated by the arrow in FIG. ”,“ Travel distance ”, and“ rotation speed ”. Further, the liquid crystal panel 3 is configured to display “time”, “cooling water temperature”, and “remaining amount of fuel” in order from the center toward the lower side in the order of starting time.

  As shown in FIG. 5, when the ignition switch 16 is turned on, the liquid crystal panel 3 performs an initial display 31, and continuously expands the “time” display 32 in the vertical direction from the center to start the display 31. To do. Furthermore, from the start of “cooling water temperature”, the display 32 of “travel distance” and “cooling water temperature” starts to expand continuously in the vertical direction, and from the start of “remaining fuel”, The display 32 of “number” and “remaining amount of fuel” starts to continue in the vertical direction.

  As the display 32 is enlarged, the initial display 31 is reduced, and when the enlargement (start) of all the displays 32 is completed, the initial display 31 is switched to the display 32. As shown in FIG. 5, the liquid crystal panel 3 is configured such that the initial display 31 is broken from the central portion and proceeds in the vertical direction as the display 32 is enlarged.

  The operation of the combination meter 1 which is the display device according to the first embodiment of the present invention described above will be described focusing on the display on the liquid crystal panel 3.

  In the control device 11, the CPU 11b performs the following control according to the program stored in the memory 11c.

  When the ignition switch 16 is turned on, in FIG. 3, the control device 11 detects it and starts operation. Specifically, when the ignition switch 16 is operated to the on position, the movement of the vehicle is calculated based on the output signal from the speed sensor 12 and the pointer 22 is rotated by an angle corresponding to the calculated vehicle speed. 23 is driven. Further, the display of the liquid crystal panel 3 is controlled based on the time information counted by the CPU 11b and the detection signals from the vehicle speed sensor 12, the water temperature sensor 13, the fuel level sensor 14 and the rotation sensor 15a, and the light emitting diode 5 is controlled. Turn on.

  Hereinafter, the display of the liquid crystal panel 3 will be described with reference to FIGS. 4 and 5.

  As described above, the time (Clock) starts at the same time as the ignition switch 16 is turned on, and the travel distance (Odo) starts at 100 ms after the ignition switch 16 is turned on. The start time of the water temperature (Temp) is 200 mS after the ignition switch 16 is turned on, and the start time of the engine speed (Tacho) is 300 mS after the ignition switch 16 is turned on. The start time of the remaining amount (Fuel) is 800 mS after the ignition switch 16 is turned on.

  In accordance with the program and data stored in the memory 11c, the CPU 11b displays an initial display 32 as shown in FIG. 5 (a) at the same time when the ignition switch 16 is turned on, and displays a "time" display 32 from the center. The display 31 of “time” is started by expanding continuously in the vertical direction to the state shown in FIG.

  Furthermore, from the start of the “cooling water temperature” (200 mS after the ignition switch 16 is turned on), the display 32 of “travel distance” and “cooling water temperature” starts to expand continuously in the vertical direction. From the starting point of “fuel remaining amount” (800 mS after the ignition switch 16 is turned on), the display 32 of “the number of revolutions” and “the remaining amount of fuel” starts to expand continuously in the vertical direction.

  The CPU 11b reduces the initial display 31 as the display 32 is enlarged, and switches the initial display 31 to the display 32 when the enlargement (start) of all the displays 32 is completed. Further, the liquid crystal panel 3 is controlled so that the initial display 31 is broken from the central portion and proceeds in the vertical direction as the display 32 is enlarged.

  As shown in FIG. 1, the liquid crystal panel 3 displays the “time” of the earliest information at the center in the vertical direction indicated by the arrow in FIG. ”,“ Travel distance ”, and“ rotation speed ”. Further, the liquid crystal panel 3 is configured to display “time”, “cooling water temperature”, and “remaining amount of fuel” in order from the center toward the lower side in the order of starting time.

  Accordingly, the display of information displayed adjacent to each other in the upward and downward directions from the center of the liquid crystal panel 3 is started in the order from the earliest start point. For this reason, it is possible to give a sense of connection to the start of display of the plurality of pieces of information, and as a result, it is possible to give a sense of quality.

  Further, the display of the plurality of pieces of information is continuously enlarged from the central portion. As a result, a sense of connection can be further provided, and the display can be enjoyed and surprised.

  The combination meter 1 that is the display device according to the first embodiment of the present invention described above displays a plurality of pieces of information that are different from each other at the start time at which the display 32 can be started after the ignition switch 16 that is a power switch is turned on. The meter 1 displays a plurality of pieces of information arranged in a predetermined direction from one side to the other in the order of the start time, and information displayed adjacent to each other in a predetermined direction is displayed on the ignition switch 16. The display is configured to start in the order from the earliest start time after being turned on.

  Thereby, it is possible to give a sense of connection to the start of display of a plurality of information, and as a result, it is possible to give a high-class feeling.

  In the above example, the “time” is displayed at the center of the liquid crystal panel 3, but it is not necessary to be limited to this, and it is displayed at the lower end, the right end, etc. It can be configured to display in the order of “travel distance”, “cooling water temperature”, “number of revolutions”, and “remaining amount of fuel”.

  Further, in the above-described example, each display 2 is configured to start by continuously enlarging from the start time, but it can be configured to display all of the display 2 at the start time. That is, in FIG. 5, simultaneously with the ignition switch 16 being turned on, the state shown in FIG. 5A is displayed, and then the state shown in FIG. 5B is displayed immediately. Thereafter, the state shown in FIG. 5C is displayed at the start time of the “cooling water temperature” (200 mS after the ignition switch 16 is turned on), and the start time of the “remaining amount of fuel” (the ignition switch 16 is turned on). After 800 mS, the state shown in FIG. 5D is displayed.

  Further, after the start of all the display is completed, that is, after the state shown in FIG. 5D is displayed, a plurality of pieces of information are configured to be displayed by changing the display arrangement. be able to. Thereby, the arrangement | positioning of the display of information can be changed, obtaining the above-mentioned effect. That is, it is possible to arrange more important information at a position that is easier to see. For example, after displaying the state shown in FIG. 5 (d), the engine speed (Tacho) is displayed at the center of the liquid crystal panel 3 and the time (clock) is displayed at the upper end of the liquid crystal panel 3. And display.

  Instead of the initial display 31, it is possible to make a state in which nothing is displayed. In this case, the liquid crystal panel 3 gradually opens the screen of the display 32 in FIG.

(Second Embodiment)
FIG. 6 is a front view of the combination meter 1 which is a display device according to the second embodiment of the present invention.

  FIG. 7 is a front view showing the completion of the start of the display 72 from the initial display 71 in the combination meter 1 shown in FIG.

  In the combination meter 1 which is a vehicle meter according to the second embodiment of the present invention, unlike the first embodiment, the liquid crystal panel 3 is abolished, and the engine speed (Tacho) displayed on the liquid crystal panel 3 is changed to a pointer meter. The indicator / warning 7 is provided. The indicator / warning 7 is composed of an indicator for notifying the operating state of the equipment provided in the host vehicle and a warning for warning an abnormality of the host vehicle.

  The indicator / warning 7 is disposed in an opening provided in the design plate 8 around the speedometer 2 and the tachometer 6. Each indicator / warning 7 is composed of a translucent plate material on which a predetermined indicator or warning mark is formed, a light emitting diode provided behind this and illuminating it. Each indicator / warning 7 turns on itself (turns on a light emitting diode) to inform the information.

  The start points at which each indicator / warning 7 can start displaying the information are different from each other, and the indicators / warnings 7 are arranged in a predetermined direction in the order of the start point in the same manner as in the first embodiment. .

  Each indicator / warning 7 indicates that it is before the display start time by turning on itself until the display of the information can be started after the ignition switch 16 is turned on (before the display start time). Inform. That is, the initial display 71 (FIG. 7) is performed by this dot.

  Each indicator / warning 7 then informs that the display start time has been reached by erasing itself when it can start displaying the information (at the start of display). That is, the display 72 (FIG. 7) is started by this disappearance. That is, each indicator / warning 7 indicates that it has reached a state where it can inform the information.

  The indicator / warning 7 is arranged from the left and right ends in the left and right direction indicated by the arrows in FIG.

  Thereby, as shown in FIG. 7A, the indicator / warning 7 is displayed until the display of the information of the indicator / warning 7 at the left and right ends after the ignition switch 16 is turned on (before the display start time). Until the indicator / warning 7 is turned on, the initial display 71 is performed. Thereafter, each time the indicator / warning 7 reaches the display start time, as shown in FIGS. 7B to 7D, the indicator / warning 7 starts the display 72 by erasing itself.

  Accordingly, the display of the information displayed adjacent to each other from the left and right end portions in the left and right direction of the combination meter 1 to the center portion is started in the order from the earliest start time. Thereby, it is possible to give a sense of connection to the start of display of the plurality of pieces of information, and as a result, it is possible to give a sense of quality.

  In FIG. 6, all indicators / warnings 7 indicate the state of the initial display 71.

  The display device need not be the combination meter 1.

  Further, the start points of the plurality of information do not have to be different from each other, and the present invention can be applied even if some of them are the same.

  In addition, it is not necessary to configure the display of information displayed adjacent to each other in all directions in the order from the earliest start time, and information displayed adjacent to each other in a predetermined direction is started. It is sufficient if the display is started in the order of the time.
