Hereinafter, a vehicle warning display device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram showing the configuration of the main part, and FIG. 2 is a vehicle instrument panel to which the present invention is applied. FIGS. 3 to 5 are diagrams for explaining the operation.
A vehicle panel to which the present invention is applied is provided with an instrument panel (meter panel) 1 as shown in FIG. The meter panel 1 shows a speedometer 2 indicating the vehicle speed, a tachometer 3 indicating the engine speed, a fuel meter 4 indicating the remaining amount of fuel, a water temperature meter 5 indicating the cooling water temperature, and front and rear brake air pressures. Pressure gauges 6 and 7 are provided. In addition to these meters 2 to 7, first to third warning light panels 8 to 10 that give various warnings according to the state of the vehicle are provided.

  Each of the first to third warning light panels 8 to 10 includes various warning lights. For example, the first warning light panel 8 includes a HI beam warning light, a seat belt non-wearing warning light, A side brake warning light, a battery lamp, and the like are provided. Note that the warning lights provided on these warning light panels 8 to 10 are mainly required by law and are conventionally known.

  The meter panel 1 is provided with a display (screen display means) 11 capable of color display. The display 11 displays vehicle driving information, time, etc. (hereinafter, such display is referred to as normal display). ), And when the abnormality of the vehicle occurs, the contents of the abnormality can be displayed (hereinafter, such display is referred to as a warning display). For example, a liquid crystal display or an organic EL display is used as the display 11.

  Here, the warning content displayed on the display 11 is not limited to what is required by laws and regulations unlike the warning displayed on the warning light panels 8 to 10 described above, and it is necessary to promptly notify the driver when an abnormality occurs. Some items or items that are indispensable for safe operation of vehicles are set as warning targets. Examples of such warning target devices include a mechanical automatic transmission, an idle stop start device, an air suspension, and the like.

  As shown in FIG. 1, a controller 12 is connected to the display 11. On the input side of the controller 12, a vehicle speed sensor 13 for detecting the vehicle speed, an engine speed sensor 14 for detecting the engine speed, a water temperature sensor 15 for detecting the temperature of the cooling water, a pressure sensor 16 for detecting the pressure in the air tank, and Various sensors not shown are connected. These sensors are also connected to the speedometer 2, the tachometer 3, the water temperature gauge 5, and the pressure gauges 6 and 7, respectively. The meters 2, 3, 5 to 7 are connected to these sensors. The output value of is displayed.

Further, in the controller 12, an abnormality detection means 17, a warning display means 18, and an operation information output means (normal display means) 19 are provided. Here, the abnormality detection means 17 detects or determines an abnormality of the vehicle (or various devices) based on information from various sensors, other controllers (not shown), and the like.
Further, when an abnormality is detected by the abnormality detection means 17, the warning display means 18 gives priority to the display on the display 11 over the normal display (warning display). The warning display means 18 may be added with a function for sounding a buzzer or the like (not shown) or generating a sound.

Further, the driving information output means 19 calculates average fuel consumption, average vehicle speed, etc. based on information from various sensors and other controllers, and outputs it as vehicle driving information, or outputs the current time, etc. The information from the driving information output means 19 is displayed on the display 11 as a normal display.
Further, unless an abnormality is detected by the abnormality detection means 17, normal display is performed on the display 11. However, when an abnormality is detected, the normal display is interrupted by an instruction from the abnormality detection means 17, and a warning is displayed. It is like that.

  A changeover switch (switching means) 20 is provided in the vicinity of the display 11 or in the vicinity of the driver's seat to arbitrarily switch between a warning display and a normal display during warning display. The changeover switch 20 has a function of sequentially switching a plurality of contents of the normal display in addition to switching between the warning display and the normal display. That is, as shown in FIG. 3, the present apparatus is configured to be able to switch various information screens displayed on the display 11, and the mileage (odd / Trip), date / time, timer, alarm, fuel consumption information, driving information, etc. can be switched.

  On the other hand, the abnormality detection means 17 not only detects an abnormality, but also determines what abnormality has occurred in which part of the vehicle (or various devices) based on information from the various sensors 13 to 16. And has a function of discriminating the degree of warning in accordance with the type of device in which an abnormality has occurred and the content of the abnormality. And this abnormality detection means 17 discriminate | determines abnormality in three steps of 1-3 in order with a high warning degree. The warning degree is stored in advance in a storage unit (not shown) for each abnormality content. For example, when a transmission system abnormality is determined, the warning degree is set to 1.

Further, the warning level is associated with color information. For example, the warning information is associated with color information in the order of red, orange, and green in descending order of warning level. That is, specifically, the associations such as warning degree 1 = red, 2 = orange, and 3 = green are executed.
In the warning display means 18, when an abnormality is detected by the abnormality detection means 17, the display screen of the display 11 is switched to a warning display to display the details of the abnormality, and the background color of the display 11 at this time is detected to be abnormal. The color associated with the means 17 is set. Therefore, for example, when an abnormality with a high degree of warning is detected, a warning such as “T / M system abnormality” is displayed with a red background color. Then, the abnormality content is displayed on the display 11 to notify the driver of the occurrence of the abnormality, and by setting a background color corresponding to the warning level, the driver is visually and intuitively notified of the warning level. .

By the way, as described above, in the present apparatus, the change-over switch 20 can be operated so that other information can be confirmed even when a warning is being displayed, thereby switching to the original normal display.
However, if the display is switched to the normal display while the warning is being displayed (during the occurrence of an abnormality), the driver may forget the occurrence of the abnormality and continue driving as usual.

  Therefore, in the present apparatus, when the display 11 is switched to the normal display even though the warning is being displayed, the edge of the display screen of the display 11 is displayed as a border over the entire circumference. The situation can be appropriately determined according to the size of the entire display and the size of a display screen portion (dead space) that is not used for information transmission. In this embodiment, several dots (for example, upper and lower 3 dots, left and right 2 dots) around the liquid crystal display 11 are trimmed. Note that such an edge may not be the entire circumference, and only a part of the edge (for example, only the left and right edges, only the upper and lower edges, etc.) may be displayed as an edge.

Therefore, even if the driver switches to the normal display during the warning display, by performing the border display on the edge of the display screen of the display 11, the normal occurrence is displayed and the abnormality is generated in the driver while satisfying the driver's request. It is possible to inform the user and avoid a situation in which the driver forgets about the occurrence of the abnormality.
The display color of the border display is set to the same color as the background color of the warning display, so that the driver can always recognize the warning level even when switching to the normal display.

When multiple abnormalities occur, the warning display displays the details of each abnormality.However, when the display is switched to the normal display after that, the color with the highest warning level is selected and the border is displayed. It is supposed to be.
Since the vehicle warning display device of the present invention is configured as described above, an example of its operation will be described with reference to FIG. First, as shown in FIG. 4A, only normal display is executed when no abnormality has occurred. In this case, as described with reference to FIG. 3, the changeover switch 20 allows the driver to arbitrarily select information he wants to know. FIG. 4A shows a display state when average fuel consumption information and average vehicle speed information are selected.

  When the abnormality detection means 17 determines that an abnormality has occurred in the vehicle based on the information from the sensors, the abnormality content and the warning degree are determined, and the warning display screen displays the color corresponding to the warning degree as a background color. 11 display screen is switched. Switching from the normal display screen to the warning display screen is forcibly (or automatically) performed. For example, when a system abnormality occurs in the engine, the warning degree is set to 2, the color is set to orange, and, as shown in FIG. 4B, a chest in which the system abnormality has occurred in the engine is displayed as a warning. Further, when a predetermined time has elapsed from this warning display, as shown in FIG. 4C, a warning prompting the driver to respond such as “Please stop at a safe place” is displayed.

  In this case, unless the occupant (mainly the driver) switches the screen, the warning shown in FIG. 4C continues to be displayed, but the occupant operates the changeover switch 20 to know other information (for example, average fuel consumption). When the screen of the display 11 is switched to the normal display, as shown in FIG. 4D, the edge of the screen of the display 11 has the same color as the background color of the warning display (in this case) , Orange) is displayed in color (border display).

Therefore, the driver can always recognize the abnormality of the vehicle even when switching to the normal display, and can avoid running for a long time in the abnormal state. Furthermore, it is possible to make the driver always recognize the degree of warning (severity).
In addition, when a plurality of abnormalities occur, the contents of each abnormality are displayed as shown in FIG. 5A, and when the display is switched to the normal display, the color with the highest warning level among the plurality of abnormalities is displayed. Since the portion is colored, the driver can be made aware of the seriousness of the warning. In FIG. 5A, a warning is given when a transmission abnormality occurs in the vehicle, the cooling water amount is insufficient (all warning level 1, background color: red), and an engine system abnormality (warning level 2, background color: orange) occurs. It is an example of a display, (b) is a figure which shows the case where it switches to normal display (in this case, comparison with the past average fuel consumption and the present average fuel consumption) during such warning display.

  As described above, according to the present apparatus, when the display is switched to the normal display when an abnormality occurs in the vehicle, the edge of the display 11 is displayed in a framed manner, so that the abnormality is generated while displaying the contents of the normal display on the driver. Can inform the driver. Therefore, since the driver can surely recognize the abnormality of the vehicle, there is an advantage that the situation where the driver forgets the occurrence of the abnormality and keeps running as usual can be avoided and safety can be improved. Further, since it is not necessary to add other parts for the warning display, it is not necessary to provide a new installation space and the cost is not increased.

  In addition, since only a part or all of the edge of the display 11 is displayed in a framed manner, the display other than the edge can be the same as the normal display, and the driver does not feel uncomfortable. In addition, since it is not necessary to change the display contents (arrangement and color scheme) in the display 11, a newly added program can be reduced. In particular, since the edge of the display screen of the display 11 is a dead space that is not normally used for information display, there is an advantage that a warning can be issued to the driver without sacrificing normal information display.

  In addition, this invention is not limited to such embodiment, A various deformation | transformation is possible. For example, when switching to normal display during warning display, the border area of the display 11 may be increased as the warning level increases. Further, the border may be blinked when switching to the normal display during the warning display. In this case, it is preferable to increase the blinking speed of the border as the degree of warning increases. And also when comprised in this way, the effect similar to the above-mentioned embodiment can be acquired. Further, the warning level is not limited to three levels as in this embodiment, and may be set to two levels or four or more levels.
