The CRT returns to a normal display after this turning-over of contents, but when the each function selecting key 22 of an operating key board 20, e.g., a trouble monitoring key is depressed when a vehicle stops, a required picture is indicated in the order of higher priority for a long period, e.g., for 5min.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vehicle display system, and more particularly to an improved vehicle display system that can correctly inform occupants of the functions of the vehicle itself or the various auxiliary equipment installed on the vehicle. .

In recent years, vehicles have been equipped with function displays that self-diagnose and display their driving conditions or engine conditions, and have also been provided with means for displaying the functions of various auxiliary machines. The various functions mentioned above include driving information, failure monitor, and diagnostic information for the vehicle itself, and the auxiliary equipment installed in the vehicle includes air conditioners, audio, television, navigation systems, maintenance memory, etc. In recent years, the number of functions has increased more and more, and in order to properly inform passengers, especially the driver, of these complex functions, vehicle display devices must be easy to read and provide optimal information as needed. There must be.

In conventional general vehicle display devices, separate display sections are provided in the vehicle interior for each of the predetermined counting functions, and necessary displays are provided by these display sections. For this reason, in the conventional device, the space of the display device inside the vehicle increases, and the reading becomes complicated, which causes problems such as interfering with driving the vehicle.

As a conventional improved vehicle display device, KOR inside the vehicle
A device has been proposed that uses a T (anode ray tube) to display the various information mentioned above. According to such a CRT, any information can be displayed as an image as needed, so the range of its use can be significantly expanded. There are hopes that this will be the case.

According to this new display method, the conventional display of simply lighting or blinking lamps can be further developed or made more complex, and the necessary digital display, graphic display, and other relatively large amounts of information can be provided to the crew. It has also become possible to display information in an interactive format based on input from passengers.

However, on the other hand, when such a versatile display system is adopted, a large capacity display can be easily performed, and new needs have arisen for its control system as well.

For example, when handling a failure or diagnosis monitor using this display method, it is possible to display not only the failure location (but also the treatment procedure at that time) on the screen at the same time.
Inevitably, one screen will be required for one failure, and from this, if multiple failures occur at the same time, *If you do not turn over several images, you will not be able to see the entire screen. A problem has arisen in that the state of the vehicle cannot be ascertained.

Conventionally, in the case of multiple simultaneous failures or other maintenance warnings such as maintenance memory, there has been a drawback that it is troublesome to operate multiple images or turn pages.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to sequentially display related screens within a predetermined selected function mode by only key operations for selecting the function mode. An object of the present invention is to provide an improved vehicle display method for display output.

In order to achieve the above object, the present invention provides a display system for a vehicle in which various information is displayed using an ORT installed in a vehicle interior and its operating keys. Display multiple different screens,
The screen switching is performed only by operating a function mode P selection key provided on the operating keypad.

Preferred embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a preferred embodiment of a vehicle to which the display method according to the present invention is applied, and the instrument panel has a built-in 0RTIO for displaying various functions for the vehicle. In order to switch and control the display and various function modes, the present invention uses a key mead 20.
Is there a key in the example? The keypad 20 is made up of a remote control keypad that can be removed from the instrument nozzle and can be operated at will by a vehicle occupant, and can switch the function mode and display using infrared beams. and key ty-)'2
The switching command from 0 is received by the remote controller 23, and based on this received signal, the functions of various auxiliary devices 24 are controlled, or the display of 0RT10 is switched independently.

A characteristic feature of the present invention is that when the screen display of the 0RTIO is required, when the necessary situation such as a failure occurs, the related multiple screen displays are automatically displayed in sequence for a short period of time, and thereby, The objective is to enable the occupant to grasp an overall overview of the failure and other matters, and then to enable the necessary screens to be sequentially displayed for a required length of time by manual operation by the occupant.

Figures 2 and 3 show actual examples of the C RTIO display screen according to the present invention, both of which are examples of failure monitors; Figure 2 shows the case of a blown fuse, and Figure 3 shows the case of an exhaust pipe. Indicates abnormal overheating.

As is clear from the above figures, the CRTIO screen displays c1 failures per screen, and the screen contains detailed information that is much easier to read than the conventional lamp display.

However, since one screen displays one failure, when multiple failures occur at the same time, the crew may not be able to see all of them and may not be able to take appropriate action.

In this regard, in the present invention, related screens are switched and displayed by manual operation as necessary.

FIG. 4 shows a flow diagram of a first preferred embodiment of the display system according to the present invention.

The display method starts when the ignition switch is turned on, and in normal cases, that is, when there is no failure, 0 RTIO
is showing the normal speedometer display. In this normal state, when the corresponding item malfunctions or maintenance memory is activated, for example, when the corresponding item occurs, such as when the engine oil has been changed for a preset number of kilometers, this is detected.
RTIO automatically displays related screens one at a time for a short period of time, in this embodiment 10 seconds. Therefore, even if a failure or a plurality of maintenance memory required items occur at the same time, the display will continue for a short period of 10 seconds until all of these relevant items are displayed, and all the necessary screens will be displayed.

From the above display, the occupant can roughly grasp the current state of the vehicle, and can appropriately select the next action to be taken.

After the automatic table of contents has been turned over, the 0RT10 returns to the normal speedometer display, but the occupants are asked to take appropriate action by turning over the table of contents, and are aware that they are about to stop the vehicle. Manual reading. In the embodiment, this manual reading is performed by manual operation of each function mode selection key 22 provided on the operation key date 2o. For example, when the failure monitor is activated, the function mode selection By pressing the failure monitor key in the key 22, the necessary screens are displayed in order of priority for a long period of time.

In the embodiment, the required long time is set to 5 minutes each, and is continuously displayed for 5 minutes after the failure monitor mode selection key 22 is operated.

Then, after 5 minutes have passed, the next highest priority screen will be displayed on the 01'LT10 screen, this will be repeated until all related screens are displayed, and finally the 0RTlO will automatically display the normal speedometer. to return to.

As described above, according to the present invention, related screens can be switched only by operating the function mode selection key provided on the operating keypad, and necessary related screens can be sequentially read out with an extremely simple operation. It becomes possible.

FIG. 5 shows a second embodiment of the display system according to the present invention, which is almost the same as the first embodiment, but differs in the manual page-turning part.

In the second embodiment, the screen page turning by manual operation continues until the selection key 22 is pressed by operating the function mode selection key 22, and only by the next selection key operation is the page turned to the display of the next higher priority screen. It is characterized by the fact that it is turned over.

When the front or sock key 24 is operated, the corresponding page remains displayed permanently, and the only way to release it is to operate the function mode selection key again.With this system, any malfunction will not occur. On the other hand, it is possible to display the screen continuously until the repair is completed, and when the repair is completed, the function mode P selection key can be operated to switch to the next screen.

Of course, if the screen lock key 24 is not operated, the next screen can be displayed sequentially every 5 minutes, as in the first embodiment.

As explained above, according to the present invention, when each function mode has a plurality of display screens, the screens within the several function modes can be switched one after another only by operating the corresponding function mode selection key. This makes it extremely easy to read all faults when a fault occurs, and for other functions such as audio control, the receiving station frequency screen, graphic display of the speaker system, and other related screens can be displayed one after another on a single screen. It becomes possible to select only with the function mode display key, and it becomes possible to use the ORT extremely effectively to provide an easy-to-read display.
