Abstract

When an abnormality occurs, a warning is effectively transmitted to the driver without causing the driver to be dazzled by the brightness of the display, and when a plurality of abnormalities occur, a warning with high importance Facilitates discrimination from warnings of low importance.
When at least one of a plurality of warning display designs is illuminated, when a warning display command for illuminating at least one of the other warning display designs is input, the first illumination is already performed. The display priority assigned to the warning display design and the display priority assigned to the second warning display design instructed to be illuminated by the warning display command are discriminated (S18). Of the first warning display design and the second warning display design, the illumination luminance of the warning display design with a low display priority is lowered with respect to the illumination luminance of the warning display design with a high display priority (S19).

Description

  The present invention relates to a vehicle display device that can be used as an automobile meter, and more particularly to a vehicle display device that includes an illumination unit for illuminating a meter or a warning display design formed on the meter.

  Automotive meters placed in front of the driver's seat generally require instruments such as speedometers for displaying vehicle speed, tachometers for displaying engine speed, and various warning display designs. Accordingly, a warning display unit is provided for displaying (when an abnormality occurs). Typical examples of warning display designs include engine oil pressure abnormality, cooling water remaining amount abnormality, brake abnormality, and exhaust temperature abnormality.

  In general, an automobile meter is equipped with an illumination device for illuminating a meter so that the driver can easily recognize the display contents even when the automobile passes through a dark place or at night. That is, when it is dark, the light source of the lighting device is turned on to illuminate the instrument. In the case of an automobile meter called a so-called black face meter, the illumination is always turned on.

  In the black face meter, the scale on the dial of the instrument is made of a light-transmitting material, and the design such as the scale that can be seen from the driver side by illuminating the dial from the back side and its surroundings Increase the contrast. Since the display such as the scale is difficult to see in the state where the illumination is not performed, it is necessary to keep the illumination on all day and night in the case of a black face meter.

  The warning display unit of the automobile meter is provided with a design such as a figure, a mark, or a character string representing each warning display design and illumination for distinguishing display / non-display of each warning display costume. That is, when the occurrence of some abnormality is detected, the corresponding illumination is turned on to warn the driver of the abnormality, and the specific warning display design is switched from the non-display to the display state.

As a conventional technique related to the present invention, for example, techniques disclosed in Patent Documents 1 to 4 are known.
In Patent Document 1, when a plurality of abnormalities occur, the priority order regarding the display of each abnormal item is identified, and the display position of the warning display (warning symbol) of each abnormal item is arranged in a position corresponding to the priority order. Is controlling.

  Patent Document 2 proposes to display a plurality of display units in different display forms so that the user can easily recognize a display with high urgency and importance. Further, as specific examples of the display form, it is disclosed to perform display negative / positive inversion and to change the display color.

  Japanese Patent Application Laid-Open No. 2004-228561 proposes a technique for easily informing the user of the entire warning and details of individual display items even when there are a plurality of display items that require warning. Specifically, the warning lamps of all display items that require a warning are turned on, and details of each display item are sequentially displayed in order of priority. Furthermore, in order to make it possible to distinguish display items whose details are being displayed, it is disclosed that a corresponding warning light is blinked and its brightness is changed.

  In Patent Document 4, when displaying an instrument such as a speedometer and a warning display as images in the panel using a liquid crystal display panel, an image that prioritizes visibility and an image that prioritizes achievement of the display purpose, We propose a technique to display properly. In other words, if the gradation or illumination brightness of the entire LCD panel display image is lowered so that the LCD display does not appear brightly to the driver's eyes at night or when passing through a dark place, the warning display image will also be difficult to see dark. This makes it difficult for the driver to notify the driver of the occurrence of an abnormality. Therefore, in Patent Document 4, in the second mode, the meter display image and the warning display image are independently controlled in the gradation ratio, and the gradation ratio and brightness of the meter display image are made variable so that the gradation and brightness at night and the like are variable. It has been proposed to control the warning display image so as to maintain the gradation and brightness. Accordingly, at night, the display image of the speedometer or the like is displayed darker than in the daytime, so that it is easy for the driver to see. In addition, the warning display image displayed when some abnormality occurs is displayed at a relatively high gradation ratio and brightness even at night, so the driver can easily generate the abnormality by the warning display image. Can be recognized.

  By the way, in the automobile meter, when an abnormality related to the main operation of the vehicle, that is, the operation of running, turning, or stopping, it is necessary to notify the driver of the abnormality with high priority. However, since there are many warning display designs on automobile meters, it is not possible for the driver to immediately distinguish whether an abnormality that has occurred is a serious abnormality from the contents of the warning display when an abnormality has occurred. Is the actual situation. In particular, when multiple abnormalities are detected, the corresponding warning display designs are in the display state (lighted state) at the same time, so it is difficult to distinguish between high-level warnings and low-level warnings. There is.

  For example, if the technique disclosed in Patent Document 1 is adopted, the display position can be controlled such that a warning display having a high importance level is displayed at a specific position among a plurality of detected abnormalities. However, the driver does not always know the position where the high-level warning display appears, and if the driver changes the posture or position, the relative positional relationship between the driver and the warning display changes. Therefore, it is difficult to distinguish the magnitude of importance only by the difference in position.

  In addition, as in Patent Document 2, it is necessary to employ an expensive display device in order to perform display negative / positive inversion or change display color in order to realize a plurality of display forms, and display control is also complicated. Therefore, an increase in device cost is inevitable.

  Further, when the technique disclosed in Patent Document 4 is adopted, only the brightness of the meter display image is lowered when the surroundings are dark, such as at night, so that the display content of the meter display image is easy to see. However, since the brightness of the warning display image does not change, the warning display may become too dazzling at night. In particular, when a plurality of warning display items are turned on at the same time, there is a possibility that the driver's vision is obscured by a warning display that is too bright, which may hinder driving.

  The present invention has been made in view of the circumstances described above, and its purpose is to effectively transmit a warning to the driver without causing the driver to be dazzled by the brightness of the display when an abnormality occurs, An object of the present invention is to provide a vehicular display device that can easily distinguish between a warning having a high importance level and a warning having a low importance level when a plurality of abnormalities have occurred.

In order to achieve the above-described object, the vehicle display device according to the present invention is characterized by the following (1) to (3).
(1) a dial plate on which a plurality of warning display designs for informing matters to be warned are formed;
A first illumination unit having a plurality of light sources for illuminating each of the warning display designs;
When a warning display command for illuminating at least one of the warning display designs is input, illumination luminance control means for controlling the illumination luminance of the light source of the first illumination unit to illuminate the warning display design;
With
When at least one of the plurality of warning display designs is illuminated, when a warning display command for illuminating at least one of the other warning display designs is input, the first warning already illuminated Display priority determining means for determining the level of the display priority assigned to the display design and the display priority assigned to the second warning display design instructed to be illuminated by the warning display command; In addition,
The illumination brightness control means is configured to set the illumination brightness of the warning display design having a low display priority among the first warning display design and the second warning display design to the illumination brightness of the warning display design having a high display priority. Lower,
thing.
(2) In the vehicle display device described in (1) above,
The dial is formed with at least one pointer driven according to a measurement value and at least a scale indicated by the pointer,
A second illuminator having at least one light source for illuminating the pointer or the scale,
The illumination luminance control means controls the illumination luminance of the light source of the second illumination unit when the warning display command for illuminating the warning display design having a display priority of a predetermined level or more is input, and the illumination luminance is controlled. Lower than steady state,
thing.
(3) In the vehicle display device according to (2),
The second illumination unit includes a first light source for illuminating the scale, and a second light source for illuminating the pointer,
When the illumination brightness control means inputs a warning display command for illuminating a warning display design with a display priority of a predetermined level or higher, the illumination brightness of the first light source is lowered, and the illumination brightness of the second light source is Maintain steady state,
thing.

  According to the vehicular display device having the above configuration (1), it is possible to effectively notify the driver of warning indication items having a high display priority without obscuring the driver's vision due to the brightness of the display. it can. That is, even when multiple abnormalities occur and multiple warning display items are displayed (lighted) at the same time, the illumination brightness of the warning display item with a low display priority is set to the warning display item with a high display priority. Therefore, a warning with high importance can be reliably transmitted to the driver without increasing the overall luminance. In addition, the driver can easily discriminate between a warning with high importance and a warning with low importance due to the difference in illumination brightness.

  According to the vehicle display device having the configuration of (2) above, when an abnormality occurs and the warning display is turned on, the illuminance of the illumination for illuminating the instrument is automatically lowered from the steady state. Even if the brightness of the vehicle is not increased, the warning display is relatively conspicuous, and the occurrence of abnormality can be effectively communicated to the driver.

  According to the vehicle display device having the configuration (3) above, when the warning display is turned on, the illumination brightness of the scale of the instrument is lower than the steady state, but the illumination brightness of the pointer of the instrument is lower than the illumination brightness of the scale. Maintained high. Accordingly, when the warning display is turned on, the scale of the instrument is somewhat difficult to read, but the position of the pointer is clearly displayed, so the driver can grasp the approximate numerical value indicated by the pointer of the instrument from the position of the pointer.

  According to the vehicle display device of the present invention, when an abnormality occurs, a warning can be effectively transmitted to the driver without causing the driver to be dazzled by the brightness of the display. In addition, when a plurality of abnormalities occur, it is easy to distinguish between a high importance warning and a low importance warning due to differences in illumination brightness.

  The present invention has been briefly described above. Further, details of the present invention will be further clarified by reading through the modes for carrying out the invention described below with reference to the accompanying drawings.

It is a front view which shows the external appearance of a part of the display apparatus for vehicles of embodiment. It is a block diagram which shows the structure of the electric circuit of the display apparatus for vehicles shown in FIG. It is a flowchart which shows the main control operations of the display apparatus for vehicles shown in FIG.

  Embodiments relating to the vehicle display device of the present invention will be described below with reference to FIGS. The appearance of a part of the vehicle display device of the present embodiment is shown in FIG. The component shown in FIG. 1 represents the vicinity of the engine tachometer 10 included in the automobile meter. In addition to the engine tachometer 10, the car meter mounted on an actual car includes a meter that displays the vehicle speed, a thermometer that displays the temperature of the cooling water, and a fuel gauge that displays the remaining amount of fuel. In many cases.

  The components of the vehicle display device including the engine tachometer 10 shown in FIG. 1 are installed in front of the driver's seat of the automobile so that the display contents can be clearly seen from the driver. The engine tachometer 10 is provided with a dial 11 formed in a substantially circular shape. On the front side of the dial plate 11 (the side close to the driver), there is a turn 12 made of transparent or translucent resin or glass. This lookback 12 is provided in order to prevent external light such as direct sunlight from being reflected on the driver side and becoming difficult to see the display.

  As shown in FIG. 1, a pointer portion 13, a scale portion 14, and a warning display portion 15 are provided on the dial 11. The pointer portion 13 has a pointer that rotates around a rotation shaft disposed at a substantially central portion of the dial plate 11 and indicates a measured value, that is, an engine speed, according to the direction of the pointer.

  The scale portion 14 has a design including a scale formed in an arc shape along the outer periphery of the dial 11 at substantially equal intervals, a numerical value represented by each scale, and a display content of “× 1000 r / min”. . Each of these designs is formed in a shape that can read the position and numerical value of the scale, and is made of a transparent or translucent material.

  The warning display unit 15 includes six warning display designs 15a to 15f in order to enable display of six types of items to be warned (hereinafter, sometimes referred to as warning display items). Each of the warning display designs 15a to 15f has a shape of a symbol mark related to the assigned warning display item, and is made of a transparent or translucent material.

  The pointer of the pointer portion 13 on the dial 11 and the design of the scale portion 14 and the warning display portion 15 are formed so as not to stand out, so that even if the surroundings are bright as in the daytime, The displayed content is difficult to see. Therefore, in order to clearly display the elements of each design so as to be visible to the driver, it is necessary to always perform illumination.

  A number of illumination light sources are provided on the back side of the dial 11 in order to illuminate the design elements of the pointer part 13, the scale part 14, and the warning display part 15. When each light source is turned on, the illumination light passes through the elements of the facing design and is displayed as a display content to the driver.

  Each of the six warning display designs 15a to 15f is turned on when the corresponding abnormality occurs, and is turned off when there is no abnormality. When a plurality of abnormalities occur, a plurality of warning display designs 15a to 15f are simultaneously turned on by illumination, and a plurality of warning displays are displayed.

  Specific examples of the warning display items corresponding to the warning display designs 15a to 15f include a decrease in the remaining amount of cooling water, a decrease in the remaining amount of engine oil, lighting of the headlight high beam, brake abnormality, exhaust temperature abnormality, battery voltage abnormality, and the like.

  Note that the dial 11 itself is also made of a translucent material, and the background area other than the pointer part 13, the scale part 14 and the warning display part 15 is also displayed so as to be dimly lit by the illumination light from the back side. Is done.

  Next, the configuration of the electric circuit will be described. FIG. 2 shows the configuration of the electric circuit of the vehicle display device including the engine tachometer 10 shown in FIG. As shown in FIG. 2, the electric circuit of the vehicle display device includes a microcomputer (CPU) 110, a power supply circuit 120, interfaces 130 and 140, operation switches 150, a motor driver 160, a liquid crystal display (LCD) 170, A liquid crystal driver 180, a nonvolatile memory (EEPROM) 190, an instrument illumination unit 210, a warning display illumination unit 220, and electric motors M1 and M2 are provided.

  The microcomputer 110 is a control unit for performing various controls related to the vehicle display device, and includes a microprocessor, a read-only memory (ROM) that holds predetermined programs and data, a readable / writable memory (RAM), and a communication function. Built-in (CAN: Controller Area Network).

  The power supply circuit 120 generates a stabilized DC voltage (VCC, VH) and a reset signal from the voltage (+ B) of the vehicle battery. A DC voltage (VCC) and a reset signal (RESE) are supplied from the output of the power supply circuit 120 to the input of the microcomputer 110.

  The interfaces 130 and 140 are used for signal conversion and noise removal. An ignition signal IGN generated in conjunction with the operation of the engine key is input to the microcomputer 110 via the interface 130. A signal (CA) appearing on the CAN communication path, for example, information such as engine speed and vehicle speed used for display on the vehicle display device, and information indicating the occurrence and state of various abnormalities are transmitted via the interface 140. Input to the microcomputer 110.

  The operation switch 150 connected to the input port of the microcomputer 110 is a switch that can be operated by the driver, and is used for resetting the distance meter (odometer / trip meter) and resetting the warning display. .

  The electric motor M1 shown in FIG. 3 has a drive shaft connected to a drive mechanism (not shown) that drives the pointer portion 13 of the engine tachometer 10, and indicates the engine speed by changing the direction of the pointer. Used. The electric motor M2 has a drive shaft connected to a drive mechanism (not shown) that drives a pointer of a vehicle speedometer (not shown), and is used to indicate the vehicle speed by changing the direction of the pointer.

  The two electric motors M1 and M2 are connected to the microcomputer 110 via the motor driver 160. Further, a sensor for detecting the position of each driven pointer is provided in the vicinity of each electric motor M1, M2, and the microcomputer 110 can grasp the position (orientation) of each pointer by a signal output from the sensor. The microcomputer 110 drives each of the electric motors M1 and M2 so that the correspondence between the measured values of the engine speed and the vehicle speed and the direction and scale of the pointer that indicates the engine speed matches.

  The liquid crystal display 170 has a function of displaying various information such as character strings. The liquid crystal display 170 is connected to the microcomputer 110 via the liquid crystal driver 180. The microcomputer 110 displays various information input via the CAN communication path, for example, the travel distance and time on the liquid crystal display 170 as necessary.

  The non-volatile memory 190 holds in advance various information that the microcomputer 110 uses for control. For example, a priority table that holds the priorities of a plurality of warning display items also exists on the nonvolatile memory 190.

  The instrument illumination unit 210 includes a number of light emitting diodes (LEDs) for illuminating each part of the instrument. For example, a light-emitting diode that illuminates the pointer of the pointer portion 13 of the engine tachometer 10 shown in FIG. 1, each scale of the scale portion 14, a number that represents a numerical value of the scale, and a design of “× 1000 r / min” are illuminated. A light emitting diode is included in the instrument illumination unit 210.

  Among the light-emitting diodes of the instrument illumination unit 210, the light-emitting diodes that illuminate the pointer and the light-emitting diodes that illuminate other locations are different output ports of the microcomputer 110 in order to independently control the light emission luminance, that is, the illumination luminance. It is connected to the. The light emission luminance of each light-emitting diode when it is lit is turned on and off alternately and periodically by a pulsed control signal output from the microcomputer 110, and the ratio (duty) between the on time and the off time. It can be controlled by changing.

  The warning display illumination unit 220 includes six light emitting diodes (LEDs) for independently illuminating (displaying) the warning display designs 15a to 15f of the warning display unit 15. These light emitting diodes are connected to different output ports of the microcomputer 110 in order to independently control the light emission luminance, that is, the illumination luminance.

  The contents of the control related to the illumination of the vehicle display device shown in FIG. 2 are shown in FIG. The control shown in FIG. 3 is realized by the processing of the microcomputer 110. Actually, in addition to the control shown in FIG. 3, the control for communication, the control for driving the electric motors M1 and M2 to move the pointer of each meter, and the display content of the liquid crystal display 170 are controlled. These processes are executed by the microcomputer 110.

The contents of the control shown in FIG. 3 will be described below.
In step S11, in order to reset the operation of the vehicular display device, the microcomputer 110 initializes the stored contents and the control state. For example, all the warning display illumination units 220 that perform illumination related to the warning display are turned off to hide the warning display, and each of them is stored in a non-display state. As for illumination of each instrument, since the instrument cannot be seen from the driver unless it is illuminated day or night, each light emitting diode of the instrument illumination unit 210 is always lit.

  In step S12, the microcomputer 110 identifies whether a warning display command has been input. When an electronic control unit (ECU: not shown) that manages the automobile detects the occurrence of any abnormality on the automobile, it inputs a warning display command to warn it to the microcomputer 110 via the interface 140. To do. This warning display command includes information on warning display items to be displayed. In step S12, the microcomputer 110 identifies whether this warning display command has been input.

  In step S13, the microcomputer 110 examines the contents of the input warning display command and identifies warning display items. In other words, it is identified which warning should be issued among a decrease in the remaining amount of cooling water, a decrease in the remaining amount of engine oil, lighting of the headlight high beam, brake abnormality, exhaust temperature abnormality, battery voltage abnormality, and the like.

  In step S14, the microcomputer 110 switches the light emitting diodes (specific light emitting diodes in the warning display illumination unit 220) that illuminate the warning display designs 15a to 15f corresponding to the warning display items identified in step S13 to a lighting state.

  In step S15, the microcomputer 110 stores the control state of the warning display item whose illumination is switched to the lighting state (displayed the warning) in step S14 as a display state in a predetermined area on the internal memory.

  In step S <b> 16, the microcomputer 110 identifies whether the illumination of other warning display items other than the warning display item corresponding to the warning display command input this time is already on. Information on the control state indicating whether or not the illumination of each warning display item is on is stored in the internal memory, and is identified by referring to this information. If the other warning display items are already lit, the process proceeds to step S17, and if not, the process proceeds to step S19.

  In step S <b> 17, the microcomputer 110 refers to the contents of the priority table 50 and acquires priority information for each warning display item when the illumination is on. The priority table 50 is provided on the non-volatile memory 190, and holds priority information related to display for each warning display item.

  In other words, when an abnormality relating to the main operation of the vehicle, such as running, turning, or stopping, occurs, it is necessary to inform the driver of the abnormality with high priority. Therefore, for example, the priority of the warning display item of “brake abnormality” is determined to be higher than the priority of the warning display item of “headlight high beam on”, and such priority information is previously set as a constant. Registered in the priority table 50.

  In step S18, the microcomputer 110 compares the priority acquired in step S17 with respect to each warning display item during lighting, and the illumination of the warning display item having a relatively high priority and the warning display having a low priority. Control the lighting of the matter independently. And about the illumination of the warning display design 15a-15f corresponding to the warning display item with a low priority, the illumination brightness | luminance is lowered | hung rather than a steady state by controlling the duty of energization on / off. About the illumination of the warning display designs 15a-15f corresponding to the warning display item with a high priority, it maintains the illumination brightness of a steady state. That is, the illumination luminance of the warning display designs 15a to 15f corresponding to the warning display items having a relatively low priority is lowered than the illumination luminance of the warning display designs 15a to 15f corresponding to the warning display items having a high priority.

  As a result, a warning display item with a high priority is displayed with a relatively high illumination brightness compared to a warning display item with a low priority. High warning display items are displayed prominently. That is, the driver can immediately recognize a warning display having a high importance level among a plurality of displays. In addition, since the illumination brightness of the warning display item having a high priority is maintained in a steady state and the brightness of the entire display does not increase, a situation in which the driver's vision is not obscured by this control does not occur.

  For example, if an abnormality of “brake abnormality” occurs while lighting of the warning display designs 15a to 15f corresponding to the warning display item “headlight high beam is on”, the former priority is higher than the latter priority. Since it is low, the former illumination luminance is lower than the steady state, and the latter illumination luminance is controlled by the microcomputer 110 so as to be maintained in the steady state.

  In step S19, the microcomputer 110 controls the brightness of the instrument illumination unit 210 that illuminates each instrument. Specifically, for the illumination of relatively less important instruments, that is, each scale, each number representing the scale value, and a light emitting diode that illuminates “× 1000 r / min”, the duty of energization on / off is controlled. As a result, the illumination brightness is lowered compared to the steady state. In addition, since the display of the pointer of the pointer portion 13 is relatively high in importance, the light emitting diode that illuminates the pointer is maintained at the steady state illumination luminance.

  In the case of a vehicle display device equipped with a plurality of instruments, the illumination brightness of the speedometer and fuel gauge pointers, which are relatively important instruments, is maintained in a steady state, and the instrument having a relatively low importance. The engine tachometer pointer may be processed in step S19 so as to lower the illumination brightness in the same manner as the scale.

  In step S20, the microcomputer 110 identifies whether or not a predetermined warning cancellation command has been input. In this embodiment, when the microcomputer 110 detects that the operation switch 150 has been continuously pressed twice, it is controlled so that a warning cancel command is input. If a warning cancel command is input, the process proceeds to step S21. If not input, the process returns to step S12.

  In step S21, the microcomputer 110 turns off the illumination of the warning display designs 15a to 15f corresponding to all the warning display items, clears the memory of the display state related to the warning display items, and sets the illumination brightness of the instruments to a steady state. return.

  As described above, by performing the control shown in FIG. 3, when the illumination of a plurality of warning display items is turned on simultaneously and displayed, the illumination brightness of the low priority warning display items is automatically set. Therefore, when a high-priority warning occurs, the driver can immediately recognize the display of the high-priority warning display item without being obscured by the lighting. Further, when displaying a warning, the illumination brightness of the instrument other than the warning display is also lowered, so that the display of the warning display item with a high priority becomes more conspicuous. The control of the illumination brightness can be easily changed by adjusting the duty for controlling the light source such as the light emitting diode, so that it is not necessary to add a special component, and the cost of the apparatus can be suppressed.

  The above embodiment assumes the case of a black face meter that constantly illuminates the instruments, but the illumination of the instruments is when the surroundings are dark, such as when passing through a dark place or at night. You may control so that it only lights.
