Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention provides driving information including the fuel efficiency of a car, the distance it can travel with remaining fuel, etc., the status of functions related to the driving of a car, and predetermined periodic inspections. The present invention relates to a vehicle information display device for selectively displaying maintenance information indicating whether or not maintenance has been performed.

<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 driving of the vehicle are set, and signals indicating abnormal conditions at these points are sent in a predetermined priority order according to the degree of danger. A central warning device for a vehicle that generates a warning command signal has been proposed. Also, JP-A-57-1
Publication No. 2322 proposes a method for determining the remaining amount of fuel and fuel consumption, and calculating the possible cruising distance of a vehicle based on these data.

Such information display devices are useful for drivers to more accurately grasp the status of the vehicle, but as the number of information items to be displayed increases, handling of the display device becomes complicated and its use becomes difficult. Sexual problems are likely to occur.

<Problems to be Solved by the Invention> In view of the above problems of the prior art, the main object of the present invention is to provide a vehicle information display with excellent usability that allows easy selection of a large number of information items. The goal is to provide equipment.

Means for Solving the Problems According to the present invention, the present invention provides a driving information switch section that is operated to sequentially call up information on different items from among a plurality of driving information, and a plurality of maintenance points. A vehicle information display comprising: a maintenance information switch section that is operated to sequentially call up information on different items from among the information; and a display section that displays information on the items called up by both of the switch sections. This is accomplished by providing a device.

Function> Since the items to be displayed are classified into two groups, and information on different items is called up one after another by operating the switch section corresponding to each group, the selection operation section of the display device is is simplified, and desired information can be selected easily and quickly.

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

Similarly, if you press the trip function pushbutton 13 while these displays 31 to 35 are being displayed, the time display 30 will be obtained, and if you press this pushbutton 13 successively, the remaining distance/fuel remaining will be displayed in sequence. Display 36, trip/time display 37,
An instantaneous fuel consumption display 38 and an average fuel consumption display 39 are obtained. If the system check pushbutton 14 is pressed while these trip function displays 36 to 39 are being performed, a time display 30 is obtained.

According to this embodiment, the driving information (trip function) push button 13 is provided on the driver's seat side, and the maintenance information (system check) push button 14 is provided on the passenger seat side. This is done in consideration of the fact that the maintenance information pushbutton 14 is used relatively infrequently and is difficult to operate erroneously, whereas the maintenance information pushbutton 14 is used relatively frequently and easily.

Next, each display content will be explained in detail with respect to FIGS. 5 to 25.

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.

Figure 12 shows engine oil level display 3 under normal conditions.
3, and 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 in operation. Therefore, the engine oil level is checked when the ignition switch is turned on, and the engine oil level display 33 as shown in FIG. I'm trying to turn it on. If it is detected that the engine oil level is insufficient when the ignition switch is turned on, the display 33b as shown in FIG.
is carried out and held, the yellow lamp 41 of the display section lights up, and 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 the coolant level 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 Fig. 15, and the green lamp 40 is lit, indicating that the coolant level is correct. If it is insufficient, 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. Further, if the system check push button 14 is pressed, other display items are displayed, but when the oil level display 33 or the coolant level display 34 is displayed, the abnormality display will be displayed again.

Since both the periodic inspection time display 31 and the oil change time display 32 depend on the mileage, the state will normally change from a normal state to an abnormal state while the vehicle is running. Through the processing, display 31a (Fig. 7), display 31b (Fig. 8), display 32a, (10th
(Fig.), display 32b (Fig. 11), etc. will continue to be displayed unless the system check push button 14 is pressed, and this state will be stored until it is cleared by pressing the service reset key 26. be done.

The washer fluid level display 35 is obtained by constantly monitoring the washer fluid -13 level, and the abnormality display 35a (Fig. 19) is displayed at the same time when the washer fluid level falls below the specified value, and the washer fluid is refilled. If this is done, the normal display 35 (FIG. 18) will be immediately obtained. The key 28 is used for setting the time or resetting the odometer value.

FIG. 20 shows the drivable distance display 36, which continuously calculates and displays the drivable distance based on the average fuel consumption calculated as described later from the time the key 24 is pressed when the tank is full. It is something.

However, as the amount remaining in the fuel tank decreases, this display can have a considerable error, so
For example, when the remaining amount in the tank becomes 2.5 gallons or less, the display is switched to the remaining fuel amount display 36a (FIG. 22). At the same time, the yellow lamp 41 is turned on to prompt refueling.

Furthermore, when the remaining amount in the tank is less than 1 gallon, a display 36b (Fig. 22) to that effect is displayed, and a yellow lamp 4
1 is lit, and a warning lamp in the instrument panel 6 is lit to urge the driver to replenish the fuel immediately. If the reset key 29 is held down for 3 seconds or more while this mode is being displayed, the remaining fuel will be reset to the value when the tank is full.

FIG. 23 shows a state where the trip display 37 is displayed together with the time. This trip display 37 is reset by pressing and holding the trip reset key 25 for 2 seconds or more.

FIG. 24 shows the instantaneous fuel consumption display 38, which is calculated by dividing the 2-second mileage by the 2-second injector flow rate. The injector flow rate is calculated by the following formula.

F = Ton X KOn -N
X Ker However, F is the injector flow rate (cc
), 'ron represents the fuel injection time (seconds), KOn represents the fuel injection coefficient (cc/second), N represents the number of fuel injections (times), and Ker represents the invalid injection coefficient (cc/times).

FIG. 25 shows the average fuel efficiency display 39, which shows the average fuel efficiency calculated by dividing the mileage after resetting by the fuel efficiency reset key 24 by the injector flow rate after resetting by the fuel efficiency reset key 24. It is.

In displays 31, 32, 36 to 39, etc., the distance or amount of fuel is displayed, but by pressing the key 23,
Units can be switched between miles/gallons and kilometers/liters. For example, in display 38 of FIG. 24, mile/gallon display 42 is shown,
In Figure 25, kilometer/liter display 43
is being carried out.

<Effects of the Invention> As described above, according to the present invention, it is possible to display multiple items of information without complicating the operation, and the usability is good, so that the rational management of vehicles is facilitated. It becomes possible.
