Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to electronic instrument panels for vehicles.

[Month of invention]

For example, as a method for displaying the mileage of product 31, JP-A-55-1
No. 03409 is known.

4'lt n Distance 1iiiif is stored, and conventionally, the distance traveled since the vehicle was manufactured is Il'D P;
It also has an engine oil change alarm, a tire rotation alarm, and other functions that issue an alarm when a preset distance is reached.

However, such cumulative distance is stored in, for example, a trip meter, and only one point in time can be set, so for example, when driving, the distance traveled from the starting point is displayed, but the distance traveled during that time is For example, information such as the distance traveled from a resting place or the distance traveled from a refueling place had to be calculated by recording the odometer or trip meter values each time.

[Inventive consideration]

Therefore, an object of the present invention is to provide an electronic instrument panel that can display the distance from a predetermined point to an origin point with a simple configuration.

[Summary of the invention]

In order to achieve such an object, the present invention provides a nonvolatile memory that sequentially stores cumulative distance, and an operation that calculates the distance from a predetermined point to the origin based on information stored in the nonvolatile memory. The computer includes a calculator and a display that displays information obtained by the calculator.

[Embodiments of the invention]

Japanese Patent Publication No. 55-103409 is known as the Ichiko Keiki board.

The present invention will be explained in detail below using Examples.

FIG. 1 shows Plockton I, which is an embodiment of the first embodiment of the present invention. In the figure, the output of a microcomputer 1 is input to a display 3 via a drive circuit 2. The display device 3 is equipped with a speed indicator 4, a tachometer indicator 5, a caustic indicator 6, a water temperature indicator 7.11, a secondary odometer 8, and an electronic trip meter 9. The microcomputer 1 includes a nonvolatile memory 11.
is connected, and this non-volatile memory 11 stores information such as cumulative travel (b'l'fat), mileage at the time of setting for the IJ tube meter, distance set for other alarms, and information on fuel consumption bonds. has been done. The above information in the non-volatile memory 11 is displayed on a predetermined indicator of the display 3 by operating the keyboard 12. Note that this keyboard 12 is equipped with a scan switch 14 and a reset switch 15.

The microcomputer 1 operates according to the flow shown in FIG. This flow is shown in Figure 2 (
It consists of the main processing flow shown in a) and the interrupt processing shown in FIG. 2(b). The main processing is engine rotation count, engine rotation display, vehicle speed count, vehicle speed display, and remaining fuel level display.

The steps of displaying the remaining fuel amount, measuring the water temperature, displaying the water temperature, counting the distance traveled, and storing the cumulative distance in the non-volatile memory are successively repeated. Further, in the interrupt processing, it is determined whether the scan switch is ON or not by operating a keyboard switch. If it is ON, the next item in the main process is displayed, and then it is determined whether the reset switch is ON. Note that if the scan switch is not ON in the above step, the next item in the main process is not displayed and it is determined whether the reset switch is ON or OFF. When the reset switch is ON, the numerical values of the displayed items are reset and the process returns to the main process.

In addition, in the above step, the reset switch is set to O.
In the case of FF, the numerical values of the display items are not reset and the process returns to the main process.

In the electronic instrument panel configured in this way, each time the scan switch 14 of the keyboard 12 is pressed, the non-volatile memory 11 is
The information that is out of memory is displayed one after another. for example,
As shown in FIG. 3, the trip meter A is first displayed, and by pressing the reset switch 15 at this time, the cumulative distance from that point on is displayed. Next, when the scan switch 14 is pressed once, the trip meter B is displayed, and when the reset switch 15 is pressed, the cumulative distance from that point is displayed. The same holds true for the next trip meter C (steps 16 to 18 in the figure).

Next, the distance setting for the oil change time will be displayed, and by keying in the set distance on the keyboard 12 when this display appears, the distance will be set when the cumulative distance from that point reaches the set value. Even if an item is displayed on another item, it will be displayed with priority and the display will repeatedly flash as an alarm (
Step 19).

The same operation is performed at the next tire rotation (step 20) and regular inspection period (step 21). Furthermore, a settable distance alarm is output when replacing the oil filter (step 22) and replacing the plug (step 23). In addition, steps 24 to 26 in the figure are fuel consumption accumulation areas, step 24 is a display of accumulated consumption since the car was produced and started running, and step 2
5 and 26 display the cumulative fuel consumption from the time when the reset button 15 of the keyboard 12 was pressed. Further, steps 27 to 29 are average fuel efficiency areas, step 27 is the average fuel consumption since the vehicle was produced, and steps 28 and 29 are the average fuel efficiency areas mentioned above in steps 25 and 29.
It is designed to display the average fuel consumption corresponding to.

With this configuration, since an electronic odometer using a non-volatile memory number is used, it is possible to set as many trip meters as the trip meter setting allows. That is, if the initial setting is A, the product η distance at the set h point is stored in the area of memory A,
If you need information on the mileage from the time the trip meter was set, please check 1. By subtracting the settlement distance stored in the area of memory A from the li '11 distance, the traveling vehicle Mlt from the set point in time can be displayed. Therefore, at the time when you want to measure as an arbitrary trip meter, you can record them in memory areas B, C, D, etc. according to the settings, and if necessary, you can recall them and calculate and display them. It is possible.

14th period: There is a warning hakama, and while conventionally the system is such that an F: f warning is issued when the driver travels a predetermined distance, in this example, the F: f warning is issued based on changes in the vehicle width condition. The value of Jl can be freely set accordingly. That is,
Since a '+ii' type odometer using non-volatile memory is used, the setting of the 5th report timing is as described in 1. above. I.J.
As with the tube meter, it is possible to set as many as the memory capacity allows, and the periodic inspection distance, oil change distance, tire rotation distance, and other distances can be set in the memory area of the nonvolatile memory using the keyboard 12. If you memorize it, you can issue a warning when the set distance is reached.

Since each of these pieces of information is stored in nonvolatile memory, it will not be erased even if the battery is removed or the like.

〔Effect of the invention〕

As is clear from the above description, according to the electronic instrument panel according to the present invention, the distance from a predetermined point to a relevant point can be displayed with a simple configuration.
