Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle display device.

[0002]

[Prior art]

 In recent years, vehicular display devices have been proposed that use a liquid crystal display to display time and engine speed.

In such a vehicle display device, when any abnormality occurs in the vehicle, the abnormality content is displayed on the entire screen of the liquid crystal display to alert the driver and give an alarm. There is one. In other words, normally, information necessary for driving such as time and engine speed is displayed (hereinafter referred to as normal display), and when an abnormality occurs in the vehicle, the abnormality content is displayed on the entire screen of the liquid crystal display. (Alarm display). Then, when the driver confirms the details of the abnormality (hereinafter referred to as the alarm content) and presses the confirmation button (or the switch for switching the screen display), the original normal display is restored.

[0004]

[Problems to be solved by the device]

 However, when the driver concentrates on driving, the alarm display may be forgotten after a while after returning to the normal display. In such a case, the conventional method does not have a function to redisplay the alarm content that was once erased from the liquid crystal display screen, so it was not possible to respond appropriately to the alarm content.

Therefore, a method has been considered in which the alarm content is displayed small on a part of the screen of the liquid crystal display even if the normal display is restored. However, even with such a method, when a plurality of abnormalities occur at the same time and the content of the alarm increases, particularly, the alarm display that appears first (entire screen) and the alarm display that appears thereafter (one of the screens). There was a problem that the driver was confused because it was difficult to understand the relationship with the department.

The present invention has been made to solve the above problems, and an object thereof is to provide a vehicular display device capable of accurately giving a warning to a driver. .

[0007]

[Means for Solving the Problems]

 The present invention normally displays information necessary for driving the vehicle on the display screen, and when any abnormality occurs in the vehicle, first, the abnormality content is displayed on the display screen instead of the information required for driving the vehicle. When it is displayed in a large size and the driver confirms the details of the abnormality, the content of the abnormality is gradually reduced and moved to a predetermined position on the display screen. The gist of the invention is to provide a display means for displaying the abnormality content at a predetermined position on the display screen.

[0008]

[Action]

 Therefore, according to the present invention, even when a plurality of abnormalities occur at the same time and the alarm content increases, the alarm display that appears first (entire screen) and the alarm display that appears after that (a part of the screen). This makes it easier to understand the relationship and gives the driver an appropriate warning.

【Example】

 An embodiment in which the present invention is embodied in a display device for an industrial vehicle will be described below with reference to FIGS.

FIG. 1 shows a screen 1 of a liquid crystal display in a normal display. Here, there is no abnormality in the vehicle and there is no alarm content. What is required for normal operation of the industrial vehicle is a clock display (PM 3:05), a tachometer display (1000 RPM), an integrated time meter display (0053H), and the like. Therefore, these values are displayed digitally. In addition to the digital display of numerical values (1000 RPM), the tachometer display also provides an analog display using a histogram (section A in the figure) to make it easier for the driver to intuitively understand.

FIG. 2 shows a screen 1 of the liquid crystal display in the alarm display. In this example, as the content of the alarm, a case where the battery liquid is insufficient is shown. In the alarm display, the code number (E003) corresponding to the alarm content, the symbol corresponding to the alarm content (B part in the drawing; a battery is illustrated), and a text that specifically describes the alarm content (“Battery Exhaust”) ), And a sentence explaining how to respond to the alarm content (“Houjuushi Techidai”) are displayed at the same time.

In particular, the symbol corresponding to the alarm content is displayed in a large size on the entire screen of the liquid crystal display so as to increase the driver's recognition. Then, when the driver sees the alarm display shown in FIG. 2 and presses the confirmation button (or the switch for switching the screen display), the screen 1 of the liquid crystal display sequentially changes as shown in FIGS.

That is, as shown in FIGS. 3 and 4, a display other than a symbol corresponding to the alarm content (a code number corresponding to the alarm content, a sentence specifically explaining the alarm content, and a method of responding to the alarm content) (The text explaining) is erased, and only the relevant symbol is displayed so that it becomes smaller gradually.

Subsequently, as shown in FIG. 5, the symbol corresponding to the alarm content is displayed in a small size at the lower left portion (C portion in the figure) of the screen of the liquid crystal display. At this time, the small symbol displayed in the lower left part of the screen of the liquid crystal display blinks for a few seconds (about 3 seconds) and then is fixedly displayed by all lights.

Next, as shown in FIG. 6, the symbol corresponding to the alarm content is displayed small in the lower left part of the screen of the liquid crystal display, and the normal display is resumed. As a result, the driver can easily determine that the first warning display (insufficient battery fluid) remained in the lower left part of the final screen (Fig. 6).

After that, when another alarm content is output, the same processing as above is performed with the alarm display (insufficient battery liquid) that was output first remaining, and finally the lower part of the screen of the liquid crystal display. The small symbols are arranged in order from the left side.

Therefore, even when a plurality of abnormalities occur at the same time and the alarm content increases, it is possible to determine the relationship between the first alarm content (entire screen) and the subsequent alarm content (part of the screen). Easy to drive and no more confusion for the driver.

The present invention is not limited to the above embodiment, but may be carried out as follows. 1) In the normal display shown in FIGS. 1 and 6, displays other than those shown (speedometer display, etc.) are performed.

2) In FIGS. 3 to 5, displays other than the symbols corresponding to the alarm contents (code numbers corresponding to the alarm contents, texts specifically explaining the alarm contents, and texts explaining a response method to the alarm contents ) Is left without being erased.

3) In the alarm display shown in FIG. 2, the code number corresponding to the alarm content, the symbol corresponding to the alarm content, the text specifically describing the alarm content, and the text describing the method of responding to the alarm content are all at the same time. Instead of displaying only the appropriate ones (eg symbols and corresponding methods) are displayed.

4) In FIG. 5, the symbol corresponding to the alarm content is not blinked. 5) In FIGS. 3 to 6, the symbols corresponding to the alarm contents are displayed gradually smaller and are not left on the final screen, but the code numbers corresponding to the alarm contents or the texts specifically explaining the alarm contents. Is displayed so that it becomes smaller and remains on the final screen.

6) On the final screen, the symbol corresponding to the alarm content is displayed at an appropriate position other than the lower part of the screen. 7) Display using a CRT or plasma display instead of a liquid crystal display.

8) It is applied to vehicles other than industrial vehicles (for example, passenger cars). 9) It is carried out by appropriately combining the above 1) to 8).
