Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides a method for selectively displaying maintenance information indicating the status of functions related to the running of an automobile or whether or not a predetermined periodic inspection has been performed. The present invention relates to a vehicle information display device.

<Prior Art> Various types of information display devices have been proposed for displaying the driving status of a vehicle or the status of each part of the vehicle.

For example, in Japanese Patent Publication No. 51-20787, several inspection points necessary for safe vehicle driving are set, and warning signals indicating abnormal conditions at these points are sent in a predetermined priority order according to the degree of danger. A central warning system for a vehicle that generates a command signal has been proposed. Since the display section of such an information display device is small, the amount of information that can be displayed simultaneously is limited. Therefore, for example, if a plurality of abnormalities occur in the vehicle condition, the driver may be able to detect only one abnormality and be unable to take appropriate action at an early stage.

Therefore, in Japanese Patent Application Laid-open No. 53-87694, the above-mentioned problem is avoided by displaying a message to that effect when there are multiple information items. However, when the display indicates that there is multiple pieces of information that should be displayed, there is a problem in that the specific abnormality is not displayed, which is inconvenient, and the information items that should be displayed are For example, there is a problem in that it is not easy to know how many abnormal locations there are.

<Problems to be Solved by the Invention> In view of the above-mentioned problems of the prior art, the main purpose of the present invention is to solve the problems in the relatively limited display area even when there are multiple information items to be displayed. An object of the present invention is to provide a vehicle information display device with an improved display circuit so that all information items can be easily recognized within the vehicle.

<Means for Solving the Problems> According to the present invention, the present invention provides a plurality of sensors for detecting the state of a vehicle, and detecting at least the state of the vehicle by receiving detection signals from the plurality of sensors. A vehicle information display device having a display section that displays one of the following: This is achieved by providing a vehicle information display device characterized by having a display means for indicating that there is other information to be displayed in addition to the information displayed on the display section by means of a signal.

When there are multiple information items that should be displayed in this way, by displaying that there are other abnormalities in part of the abnormality display for each item, the abnormalities and their number can be easily recognized. can be understood well.

Embodiments The present invention will now be described in detail with reference to specific embodiments with reference to the accompanying drawings.

FIG. 1 shows a dash board 1 for a vehicle to which a vehicle information display device according to the present invention is applied. A center console 2 equipped with audio equipment and the like is provided below the center of the dash board 1, and an air conditioner 3 and an air conditioning air outlet 4 are provided above the center console 2. In this embodiment, the information display device 5 according to the present invention is installed directly above the air outlet 4. In this embodiment, the driver's seat is provided on the left side of the vehicle interior in the direction of travel, and therefore the steering wheel 7 and the instrument panel 6 is provided on the left side of the information display device 5 or the center console 2.

FIGS. 2 and 3 show the above-mentioned information display device 5 in detail. This display device 5 consists of a relatively horizontally elongated box, with a display section 12 made of a fluorescent display tube provided at the front of the central portion, and relatively large push buttons 13 and 14 provided on the left and right sides of the display section 12. The lower ends of these push buttons 13.14 are connected to the main body via hinges 15.16, and the upper end of each push button 13.14 is provided with four parts 17.18 for engaging a finger. . These four parts 17
．． 18 by engaging a finger]; 3.
14 can be opened downward. In addition, each push button 1
Projections 8.9 are provided at the lower part of the back surface of 3.14, and these projections come into contact with elastic members 10.11 on the main body side, so that these push buttons 13.14 can be fully opened. This is to improve the opening/closing feeling of the push buttons 13.14 by always biasing the push buttons 13.14 in the closing direction except at certain times.

A protrusion 19.20 is also protruded from the rear surface of these push buttons 13.14 at a slightly upper part, and when these push buttons are pressed when the push button 13.14 is in a closed state, the protrusion 1
9.20 opens and closes the electric circuit by pressing the switch 21.22 provided on the main body side, and the push button 13
．． Fourteen functions are achieved. Furthermore, as clearly shown in FIG. 3, three and four switch keys 23 to 29 are provided on the back side of the push buttons 13 and 14, respectively.
is provided.

FIG. 4 is a conceptual diagram showing how to select information items displayed on the information display device shown in FIGS. 1 to 3, and the white arrow indicates the driving information (trip function) push button 13. The arrow with hatching indicates the action of pushing the maintenance information (system check) push button 14. Normally, a time display 30 is displayed on the display unit 12 as shown in FIG. Display 32, oil level display 33, coolant level display 34, washer fluid level display 35, and so on.
If the system check pushbutton 14 is pressed while the washer fluid level display 35 is displayed, the time display 30 will be displayed again. Furthermore, when these displays 31 to 35 are left in the selected state for a certain period of time, for example, 10 seconds, the time display 30 automatically comes to be displayed.

Similarly, pressing the trip function pushbutton 13 while these displays 31 to 35 are in progress will provide the time display 30, and pressing this pushbutton 13 successively will cause
A travelable distance/remaining fuel consumption display 36, a trip/time display 37, an instant fuel consumption display 38, and an average fuel consumption display 39 are sequentially obtained. These trip function displays 36~
If the system check pushbutton 14 is pressed while 39 is being performed, the time display 30 is obtained.

Next, display contents related to maintenance information (system check) will be explained in detail with respect to FIGS. 5 to 22.

FIG. 5 shows a normal time display 30, which is no different from a normal digital clock as far as this display is concerned.

Figure 6 shows the periodic inspection timing display 31 during normal operation.
If the periodic inspection period is set to be performed, for example, every 7,500 miles, the service reset key 2
Pressing 6 always displays the mileage until the periodic inspection time, i.e. 7.
500 miles is displayed in the upper right corner of the display section 12. When the mileage until the next periodic inspection is less than 500 miles, a display 3 to that effect will be displayed as shown in Figure 7.
1a is performed and the yellow lamp 41 lights up.

Further, if the mileage corresponding to the periodic inspection period is exceeded without performing the periodic inspection, that is, without pressing the service reset key 26, the display 31b to that effect will be displayed at the eighth
This is carried out as shown in the figure, and a warning lamp disposed within the instrument panel 6 is activated. In addition, the displays 31a and 31b are obtained by interrupt processing at the moment when the mileage corresponding to the periodic inspection period has been exceeded, and when this operation is performed, a buzzer is activated. Note that the service reset key 26 is different from other keys 2.
Unlike keys 7 to 29, it hardly protrudes from the surface of the main body, but this is to prevent this key 26 from being pressed by mistake.

FIG. 9 shows an oil change timing display 32, and in this case as well, it is set that the oil should be changed every 7,500 miles as before. When the mileage until the oil change time is less than 500 miles, a display 32a indicating that the oil should be changed by the time the vehicle travels for 500 miles is displayed, as shown by reference numeral 32a in FIG. 10, and a yellow lamp 41 lights up. Furthermore, unless an oil change is performed, that is, unless the service reset key 26 is pressed,
A display 32b to that effect is displayed (FIG. 11). The oil change time can be freely set by the user, and when the service reset key 26 is pressed continuously for 2 seconds or more, the oil change time is displayed blinking on the display section 12. Next, press the arrow key 27 and the oil change time display will show 7500 miles.
6000 miles, 5000 miles, 4000 miles...
The oil change timing can be set to correspond to the desired mileage by pressing the set key 29 when the desired oil change time is displayed.

Incidentally, since the abnormality detection operations at the periodic inspection time and the oil change time both depend on the mileage, the display 31a (Fig. ), display 31b (Fig. 8), display 32a, (Fig. 10), display 32b (first
1), etc., and these displays remain as they are unless the service reset key 26 or push button 13, 14 is pressed.

Figure 12 shows the engine oil level under normal conditions = 10
= This indicates a small display 33. During normal driving, a display 33a as shown in FIG. 13 is displayed, indicating that the engine oil level has not been detected. This is because the oil level of the engine cannot be detected because the oil level fluctuates while the engine is running. Therefore,
The engine oil level is checked when the ignition switch is turned on. If the engine oil level is appropriate, the engine oil level display 33 as shown in FIG.
Only the minutes are displayed and the green lamp 40 is turned on at the same time. If it is detected that the engine oil level is insufficient when the ignition switch is turned on, a display 33b as shown in FIG. At the same time, a warning lamp disposed within the instrument panel 6, for example, is activated. A buzzer is also activated during interrupt processing.

Figures 15 to 17 show the coolant level display 34 that indicates whether there is an excess or deficiency of engine cooling water.Since the coolant level cannot be accurately detected during engine operation, it is not possible to detect it during normal engine operation. The display 34a shown in FIG. 16 indicates that the coolant level has not been detected. The coolant level is detected when the ignition switch is turned on, and if the coolant level is appropriate, a display to that effect is displayed as shown in Figure 15, and the green lamp 40 is lit, indicating that the coolant level is insufficient. If so, a display 34b as shown in FIG. 17 is displayed, the yellow lamp 41 is turned on, and the warning lamp or warning buzzer provided in the instrument panel 6 is activated in the same manner as described above.

FIG. 18 shows the washer fluid level display 35 in a normal state, and FIG. 19 shows the washer fluid level display 35a in an abnormal state. The green lamp 40 lights up in normal times, and the yellow lamp 41 lights up in abnormal times.

Washer fluid can be detected continuously even while the vehicle is running, and as long as the washer fluid level is appropriate, the
The display 35 shown in FIG. 8 continues.

Of the display information items described above, the oil level display 33 and the coolant level 34 are performed only when the vehicle is started.If an abnormality in the oil level or coolant level is detected when the vehicle is started, the display 33b is displayed by interrupt processing. (Fig. 14) or display 34b (Fig. 17) is performed, and this state is stored until oil replenishment or coolant replenishment is performed. Furthermore, if the system check push button 14 is pressed, other display items are displayed, but the abnormal condition is still stored, and when the oil level display 33 or coolant level display 34 is performed, the abnormality display will be displayed again. becomes.

The washer fluid level display 35 is obtained by constantly monitoring the washer fluid level, and the abnormality display 35
Step a (FIG. 19) is performed at the same time as the washer fluid level falls below the specified value, and the normal display 35 (FIG. 18) is obtained immediately after the washer fluid is replenished. The key 28 is used for setting the time or resetting the odometer value.

The above displays are for cases where each abnormal location occurs alone, but next we will explain how to display when a plurality of abnormal locations occur.

In this embodiment, each abnormality is stored in the stack memory in the order of occurrence, and when a new abnormality occurs, the abnormality is displayed.

Therefore, for example, if an oil level abnormality is detected during startup, a display 33b as shown in FIG. 14 is displayed and maintained as is. At this time, if there are no other abnormalities, by pressing the push button 14, the display 34 and 35 are displayed in a predetermined order, and the time display 30 shown in FIG. 5 is displayed.
is obtained. Furthermore, by pressing the pushbuttons 14 one after another, all the inspection items display 31 are displayed in the order shown in FIG.
．． 32.33b, 34.35.30 are performed sequentially.

Next, for example, if the number of miles traveled before requiring periodic inspection is 5.
Assume that the distance is less than 00 miles. A display 31a to this effect will be performed as an interrupt process as shown in FIG. 7, but since there are two abnormalities, the actual display 31c will be as follows: As shown in Figure 20, at the end of the message II &l
An l mark 44 is added. If the push button 14 is pressed in this state, a display 33c indicating an oil level abnormality as shown in FIG. 21 will be obtained, but this display also indicates that the number of miles traveled that requires periodic inspection is approaching. , a &''' mark 44 is added to the end of the message.Furthermore, when the pushbutton 14 is pressed, unless there are other abnormalities, the display 34 and 35 are displayed in the same manner as before, in the predetermined order. The time display 30 shown in FIG. 5 is obtained.

Furthermore, when the push buttons 14 are pressed one after another, all inspection item displays 31c, 32.3 are displayed in the order shown in FIG.
3c, 34, 35, and 30 are performed sequentially.

The above procedure applies equally to other abnormal item displays. Even if an abnormal state transitions to a normal state, it is handled in the same way as the above-mentioned abnormal item display. For example, when the engine is started after replenishing engine oil, the display 33d shown in Fig. 22 is obtained, but periodic inspection Since the number of miles traveled that is approaching the required number has not been resolved,
An II &l+ mark 44 is added to the end of the message displayed in display 33d. However, regarding the abnormal item display, even if the display is once erased, the abnormal part is still retained in the stack memory and will be recalled again with priority, whereas when the abnormal state changes to the normal state, the notification will be displayed once. When displayed, it is cleared from stack memory. Therefore, if the push button 14 is pressed in this state, the time display 30 will be obtained via the displays 31c, 32.33d, and 34.35 unless there are other abnormalities, and if the push button 14 is further pushed, the display 31a, 32, 33, 34, 35, and 30 are obtained in this order.

However, for example, if the oil level abnormality display 33c (Fig. 21) is obtained after the oil change time abnormality display 32a (Fig. 10), the push button is pressed after the oil level abnormality display 33c is performed by interrupt processing. When push button 14 is pressed, the oil change time abnormal display is displayed with priority, but when push button 14 is further pressed, time display 30 is immediately obtained since display 33c has just been displayed. That is, if two abnormal displays A and B that are adjacent in the normal display order are performed, and abnormal display B that is later in the order has been performed most recently, pressing the push button 14 will display the next abnormal display in the order. The previous abnormality display A is preferentially displayed, but if the push button 14 is further pressed, the time display 30 is immediately obtained without repeating the display B that was just seen.

As can be understood from the above, abnormal states and transitions from normal states to abnormal states are displayed preferentially in the order of newest, but once the time display 30 is displayed, the above order of priority will no longer be considered. First, each display is performed in the predetermined order shown in FIG. Further, for example, when an abnormal state occurs and a transition from a normal state to an abnormal state occurs at the same time, such as during startup, the occurrence of the abnormal state may be displayed preferentially.

In the above embodiment, although the TI & TI mark indicates the presence of a plurality of abnormal locations, the actual number of abnormal locations could not be immediately grasped.

Therefore, for example, a register is provided to store the number of data stored in the stack memory, and the value is set as TI &
! It is also possible to display it next to the + mark. Also,
Other symbols can be used as appropriate in place of the &pa mark.

<Effects of the Invention> As described above, according to the present invention, even when there are multiple information items to be displayed, it is possible to easily grasp the abnormalities and their number, which not only improves the usability but also improves the usability. ,
Vehicles can be rationally managed.
