Abstract

PROBLEM TO BE SOLVED: To provide an electronic system and a program that can display a current consumption condition of fuel in a vehicle so as to make a user practically feel the condition in real time.SOLUTION: A display part 14 for a fuel display device displays a variation image in which liquid level is moved upward with flow-down of a drip pattern 32 with fuel consumption in a measuring cylinder pattern 31. The number of drips and rising speed of the liquid level are varied with the fuel consumption. When the measuring cylinder pattern 31 is fulfilled, that is, a prescribe quantity of fuel is consumed, the measuring cylinder is made void to form an initial state and a tank pattern 33 having a larger scale unit displays the variation image showing the liquid level rising of a variation portion of the measuring cylinder pattern 31. When one operation is finished, the measuring cylinder pattern 31 and the tank pattern 33 are cleared and an integrated value with the fuel consumption in this time is reflected to next operation as the variation display of an integrated pattern 36.

Description

  The present invention relates to an electronic system and a program capable of variably displaying a current fuel consumption state of a vehicle on a display means.

Currently, fossil fuels are the main energy source. However, the amount of fossil fuel used can be further reduced due to the limited reserves of fossil fuels, the greenhouse effect of emitted CO2 and the effects of air pollution caused by nitrogen oxides. It has been demanded. For this reason, various improvements have been made in vehicles that use gasoline, light oil, natural gas, or the like as an energy source so that an engine with better fuel consumption (fuel consumption rate) is mounted or cleaner exhaust gas is discharged.

JP 2007-298491 A

On the other hand, the user is not very conscious about the amount of fuel consumed. The vague image is that the driving vehicle has good fuel efficiency and clean exhaust gas, but in general it is difficult to say that this practice is reflected in driving. In other words, it is not an ecological operation that actively consumes less fuel. One of the reasons is that it is impossible to realize how much fuel is actually consumed in real time.
Of course, since the vehicle is equipped with a fuel meter, to some extent it is possible to know how much fuel has decreased at the position of the meter, but basically the fuel meter is a notification device to prevent running out of fuel, From this information, it is not possible to realize that the amount of fuel consumed in real time varies depending on the amount of fuel consumed in real time and the way of driving.
In recent vehicles, there are models that display average fuel consumption and instantaneous fuel consumption on the display as numerical values. This is shown in Patent Document 1. However, Patent Document 1 is not information that reminds the user how much fuel is consumed. For example, it is not an information tool that makes you realize, “Oh, I used gasoline so much.
Therefore, there has been a demand for a device that allows the user to realize the fuel consumption situation in real time when driving the vehicle.
The present invention has been made to solve the above problems, and an object of the present invention is to provide an electronic system and program capable of displaying the current fuel consumption state of the vehicle so that the user can realize it in real time. It is in.

In order to achieve the above object, in the first means, the control means for variably displaying the current fuel consumption state on the display means at a speed corresponding to the fuel consumption speed based on the information on the fuel consumption obtained from the vehicle. The gist is that
With such a configuration, the control means calculates the fuel consumption speed based on the fuel consumption information acquired from the vehicle, and the current fuel consumption status is displayed on the display means in a variable manner corresponding to the fuel consumption speed. The user can realize how much fuel is actually consumed in real time by visually observing the fluctuation display displayed on the display means. As a result, for example, users can feel that fuel consumption increases when driving with heavy engine load, such as sudden acceleration or high rotation, so that ecological driving should be avoided while avoiding unnecessary fuel consumption. I will keep in mind.

Here, “display means” is assumed to be, for example, an organic EL display, a liquid crystal display, or a CRT display provided with a display unit for displaying moving images and still images.
Further, “information on fuel consumption acquired from the vehicle” includes, for example, vehicle speed, injection injection time, ignition timing, intake air amount, intake air temperature, water temperature, air fuel efficiency correction coefficient, battery voltage, remaining fuel amount, The flow rate pulse from the flow meter, the amount of oil supply, the engine speed, the throttle opening (accelerator opening), the throttle sensor voltage, the airflow voltage, the boost pressure and the like can be mentioned. “Fuel” is a concept including biofuel such as alcohol in addition to fuel derived from fossil fuel such as gasoline, light oil and natural gas.
Such information can be generally obtained from a K line or a CAN (Controller Area Network) in which terminals are provided on a vehicle diagnosis connector for ODB-II (On-Board Diagnostic System Stage 2), which is required to be installed in the vehicle. However, if there is means for obtaining data from other than the vehicle diagnostic connector in the vehicle, it is also free to use it.
Here, examples of the “electronic system” include an electronic device having a casing such as a fuel consumption display device, a radar detection device, or a navigation device. Further, the display means may be integrated with the control means on the electronic system side, or may exist as a single display means that is separated and output data from the control means wirelessly or by wire. In addition, the electronic system is not necessarily installed in the vehicle. For example, it is possible to control the housing including the control means to be installed outside the vehicle, receive vehicle information wirelessly, and display the current fuel consumption status on the display means arranged in the vehicle. . Further, all of the control means do not have to be in the vehicle, and some of them may exist outside the vehicle (for example, a server).

In the second means, in addition to the first means, the display means is provided, the control means is provided in the vehicle, and the display means is disposed at a position visible to the driver in the vehicle. The gist.
Although the display means can be configured separately, it is advantageous in handling that the display means is mounted on the vehicle together with the control means in at least the main body of the electronic system. When mounted on a vehicle here, the display means is disposed in the housing of the electronic system main body where the control means is disposed, and the display means is disposed in the vehicle separately from the electronic system main body. The control means includes both cases where the connection is made wirelessly or wired by cable or the like.

The gist of the third means is that, in addition to the first or second means, the change display is a display in which an object moves, appears or disappears according to the fuel consumption.
This is a more specific configuration of the variable display on the display means. Depending on the fuel consumption, a certain object or objects move up and down or left and right, and a display that leaves the display screen, or an object that appears on the screen or conversely exists on the screen. A display that disappears can be assumed. By making these visible to the user, it is possible to give a stronger image that “fuel is currently being consumed” and to realize that fuel is being consumed. For example, the object is preferably constituted by a symbol. The same applies to the following means.
In the fourth means, in addition to the third means, the object is an object of a liquid image (hereinafter, liquid object), and the change display is a display in which the liquid object flows down according to the fuel consumption. This is the gist.
This is a more specific configuration of the variable display on the display means. In this way, by displaying a fluctuation image as if the liquid flows down as a display mode on the display unit of the display means, the user is strongly given an image that “the fuel is currently consumed” and the fuel is consumed. It is because you can feel more.
Here, "variable display" is not only a display that moves smoothly in seconds, such as animation, but also a simple and simple unit that is expressed only by lighting a light spot. It is intended to include a display that operates slowly.

In the fifth means, in addition to the fourth means, the control means displays a container image object (hereinafter referred to as a container object) on the display means, and the change display indicates that the liquid object corresponds to the fuel consumption. The gist is that the display is a display in which the liquid level flows down into the container object, or a display in which the liquid object flows out of the container object and the liquid level in the container object decreases.
This is also a more specific configuration of the variable display on the display means. Thus, as the display mode, either a variation image in which the liquid flows down into the container and the liquid level rises, or conversely, a variation image in which the liquid flows out of the container and the liquid level descends is displayed on the display means. By displaying on the display unit, it gives a strong image to the user as if the fuel is currently being consumed, and can make the user feel more that fuel is being consumed, and driving that consumes fuel wastefully It tends to refrain from.

In the sixth means, in addition to the fifth means, the speed corresponding to the consumption speed of the fuel is the amount of fluctuation of the liquid level until the inside of the container object is filled from the empty state or the inside of the container object is full. The gist of the present invention is the speed corresponding to the amount consumed at the minute level in the idling state of the engine of the vehicle.
In other words, the liquid level moves so that the container fills up from the empty state or becomes empty from the full state even in the idling state even when the fuel consumption of the driving engine is the lowest. Since the change display is displayed, it is possible to realize that fuel is consumed even when the vehicle is not actually moving, and there is a tendency to refrain from driving that consumes fuel wastefully. Become.
Here, the “minute level” is from 1 minute to 60 minutes, and at that level, the liquid level in the container repeats the state of full and empty, giving a strong image of consuming fuel. It will be. On the other hand, if the repetition timing is set to a very short time, such as a few seconds level, the state of the liquid level moving up and down is displayed rapidly. In some cases, it is difficult to recognize the vertical movement of the. On the other hand, there are cases where the minute level is relatively short from the start to the stop of the engine, so there are cases where the liquid level is not repeated up and down once when the level is several tens of minutes. Therefore, the minute level here is preferably about 1 to 10 minutes (several minutes).

In the seventh means, in addition to the fifth or sixth means, the speed corresponding to the consumption speed of the fuel is the amount of fluctuation of the liquid level until the inside of the container object is filled from the empty state or the container object. The gist is that the amount of fluctuation of the liquid level from the full state to the empty state corresponds to the amount consumed at the second level at the maximum fuel flow rate of the vehicle.
That is, the fuel is consumed most at the highest fuel flow rate, and the fuel consumption rate is the highest. If the vertical movement of the liquid level can be recognized in the state where the fuel is consumed most, the vertical movement of the liquid level can be changed with a gentler behavior even in the same second unit in the normal operation state. As a result, the user can surely visually recognize the vertical movement of the liquid level in any driving situation.
Here, the “second level” is 1 second to 60 seconds, and at that second level, the operation of repeating the liquid level in the container in the empty state and the full state is performed in one operation, which consumes fuel. Will give a strong image. In some short seconds, it may be difficult for the user to recognize the vertical movement of the liquid level. Therefore, about 3 to 10 seconds (several seconds) is preferable as the second level here.

In the eighth means, in addition to any of the fourth to seventh means, the speed corresponding to the consumption speed of the fuel is the amount of change in the liquid level until the inside of the container object is full from the empty state or The gist is that the amount of change in the liquid level from the full state of the container object to the color is determined based on the average fuel consumption or average fuel flow rate of the vehicle.
In this way, based on the average fuel consumption or average fuel flow rate, it is possible to grasp how fast the fuel is consumed, so based on that information, set the appropriate vertical movement speed of the appropriate liquid level It becomes easy. For example, assuming that the average fuel flow rate is 120 ml (milliliter) per minute, if the vertical movement interval of the container is 240 ml, one vertical movement is completed in an average of 2 minutes. Although it depends on the vertical length of the container, if it is 2 minutes, the user will have just enough time to recognize the vertical movement of the liquid level. The control means sets the amount of fluctuation of the liquid level so that one up-and-down movement is completed in a predetermined time that is appropriate in advance. In other words, it is possible to calculate the capacity of the container from the average fuel consumption or the average fuel flow rate, assuming that one up / down movement time is constant.
Here, “determined based on the average fuel consumption or average fuel flow rate of the vehicle” may be determined directly or indirectly based on information acquired from the vehicle or the user, for example, from the average fuel consumption or average fuel flow rate of the vehicle type. An optimal fluctuation timing may be selected, and the user may appropriately input the average fuel consumption or the average fuel flow rate.

In addition to any of the fourth to eighth means in the ninth means, when the control means has a change in at least one of the average fuel consumption or the average fuel flow rate, the display mode of the liquid object according to the change The gist is to change the display mode to another type of display.
As a result, when there is a change in the driving situation that affects the increase or decrease in fuel consumption, the display mode of the liquid object is quickly changed, so the user can heavier driving that leads to wasteful fuel consumption, Try to drive with good fuel efficiency. Here, “change to another type of display mode” means, for example, that the heel object, which is a liquid object, falls sparsely in an idling state where fuel consumption is low, and a large amount of heel object falls in a state where fuel consumption is high There may be cases where the numbers are displayed in different numbers, or the sizes are displayed as small and large. Also, a change such as a difference in color or a difference in shape may be used.

In the tenth means, in addition to any of the fourth to ninth means, the control means changes the display mode of the liquid object during idling according to a change in at least one information of average fuel consumption or average fuel flow rate. The gist is that the unit change amount corresponding to the fuel flow rate per unit time can be changed while being variable.
With such a configuration, the unit change amount corresponding to the fuel flow rate per unit time when the display mode of the liquid object at the time of idling varies according to the change in at least one information of the average fuel consumption or the average fuel flow rate. By changing the, it is possible to set an optimal fluctuation pattern according to the vehicle type. Here, the “unit variation corresponding to the fuel flow rate per unit time” is the fuel flow rate within a certain time corresponding to a certain variation amount of a certain object.
As a result, the following measures can be taken. For example, it is assumed that there is a case where the fuel efficiency is very good in a certain vehicle type A. If the unit change amount set as the default is to display a fluctuation display in which one soot flows down every 3 seconds at the fuel flow rate aml (milliliter) at idling, this model A has a very slow timing (for example, 30 seconds). And so on) There is a possibility that the display will change so that one kite flows down. Then, since it is too slow as a fluctuation display, in that case, the fuel flow rate corresponding to the flow of one soot is set to be smaller so as to correspond to a vehicle type with good fuel efficiency. The “unit change amount” corresponds to the acquired fuel flow rate Bp in the following embodiment.
Here, as a method of changing the “unit change amount”, the control means may select an optimal fluctuation timing from the average fuel consumption or the average fuel flow rate of the vehicle type, or the user may appropriately input it.

In the eleventh means, in addition to any of the fourth to tenth means, the control means changes the display mode of the liquid object at the maximum fuel flow rate to a change in at least one information of average fuel consumption or average fuel flow rate. The gist of the invention is that the unit change amount corresponding to the fuel flow rate per unit time can be changed.
With such a configuration, the unit corresponding to the fuel flow rate per unit time when the display mode of the liquid object at the maximum fuel flow rate varies according to the change in at least one information of the average fuel consumption or the average fuel flow rate. By changing the amount of change, it is possible to set an optimal variation pattern according to the vehicle type. The definition of “unit variation corresponding to the fuel flow rate per unit time” is as described above.
As a result, the following measures can be taken. For example, it is assumed that there is a case where the fuel efficiency is very bad in a certain vehicle type B. In the unit change amount set by default, if a change display is made such that one soot flows down per second at the fuel flow rate bml (milliliter) at the maximum fuel flow rate, this model B has a very early timing (for example, 0.1 In some cases, the display may fluctuate so that one kite flows down. Then, since it is too early as a fluctuation display, in that case, the fuel flow rate corresponding to the flow of one soot is set more so as to correspond to the vehicle type with good fuel efficiency.
Here, as a method of changing the “unit change amount”, the control means may select an optimal fluctuation timing from the average fuel consumption or the average fuel flow rate of the vehicle type, or the user may appropriately input it.
Here, it is preferable to set not only the maximum fuel flow rate side but also the minimum fuel flow rate (that is, idling) at the same time. The variation display characteristic of the variation pattern between the maximum fuel flow rate and the minimum fuel flow rate may be linear (linear function) or curvilinear (high order function).

In the twelfth means, in addition to any of the fourth to eleventh means, the speed corresponding to the fuel consumption speed does not display the object while the engine is stopped, and does not display when the engine is driven. The gist is to make it.
As a result, when there is no fuel consumption, the liquid object is not changed, and the liquid object is changed only while the engine that is consuming the fuel is being driven. As a result, the user is often made aware that he is consuming fuel. Here, since the state in which the engine is being driven and the fuel consumption is the least is the idling state, it can be interpreted here that the liquid object is changed more than the idling state.
In addition, when changing the liquid object, the number of instantaneous consumption fuel and the number of soot objects in a predetermined range may be allocated, and the number of liquid objects corresponding to the certain range of instantaneous consumption fuel may be displayed. And it is preferable that the number of soot objects to be assigned can be changed according to the average fuel consumption or average fuel flow rate of the vehicle. In the case of assignment, the control means may assign the number of soot objects as appropriate from the average fuel consumption or average fuel flow rate of the vehicle type, or the user may input it himself.

In the thirteenth means, in addition to any one of the first to twelfth means, as the change display, a plurality of different scale image objects that change in either the increasing or decreasing direction in conjunction with fuel consumption. The gist is to display (hereinafter, scale object).
As a result, a plurality of scale objects of different scale units are displayed on the screen, so that the user can simultaneously observe, for example, a scale object that fluctuates in a relatively short time to a more slowly changing scale object during driving. It is possible to obtain information on fuel consumption according to the situation.

In the fourteenth means, in addition to the thirteenth means, as the plurality of different scale objects, the scale object is filled with a scale object or becomes empty in a minute level in the idling state of the vehicle engine, the scale Is the scale object of the scale corresponding to the fuel consumption from one engine start to the engine stop, the scale object of the scale corresponding to the capacity of the fuel tank of the vehicle, the scale is the lifetime fuel consumption of the vehicle The gist is to have at least any two objects of corresponding scales.
In addition, the user can simultaneously obtain at least two of the four types of important fuel consumption information in different scale units, and can easily grasp what kind of consumption situation and consumption tendency.
Here, the “scale object corresponding to the fuel consumption from one engine start to engine stop” means the fuel consumption corresponding to the travel distance when one cycle from engine start to engine stop is relatively short For example, fuel consumption over a distance of about 5 to 20 km, such as commuting to a company, shopping in a suburban shopping mall, and picking up a child, is equivalent.

In the fifteenth means, in addition to the thirteenth or fourteenth means, among the plurality of different scale objects, when an object having a smaller scale unit becomes full or becomes empty, an object having a larger scale unit is changed to that. The gist is to provide a variable display of the full or empty capacity.
That is, when a small object of a certain scale unit becomes full or becomes empty, an object having a larger scale unit performs a predetermined variation display according to its capacity.
As a result, the display corresponding to the consumed fuel displayed by the increase / decrease of the small object in the scale unit shows the fluctuation amount in the larger object in the scale unit, so the real-time consumption situation is grasped with the small object in the scale unit. In addition, it is possible to grasp the total fuel consumption in the period that is a larger object of the scale unit.

In the sixteenth means, in addition to any of the thirteenth and fourteenth means, the plurality of different scale objects are displayed in a variable manner in either an increasing or decreasing direction in conjunction with fuel consumption. And
That is, as the fuel is consumed, a plurality of different scale objects change at the same time even if the scale units are different. Therefore, the fluctuation speed of each scale object is different from the natural one.

In the seventeenth means, in addition to any one of the first to twelfth means, as the fluctuation display, an object of an image of a first scale that fluctuates in either the increase or decrease direction in conjunction with fuel consumption ( Hereinafter, the gist is to display the scale object).
This is a more specific configuration of the variable display on the display means. In this way, as a display mode, by displaying on the display unit of the display means a scale fluctuation image that fluctuates in either the increase or decrease direction in conjunction with fuel consumption, the user is as if “the fuel is currently like this This is because it gives a quantitative image of “consumed at a certain level” in a quantitative manner and makes it possible to feel more that fuel is being consumed.
Here, the shape of the “first scale object” is not particularly limited as long as the variation is quantitative in either the increase or decrease direction. An obvious scale shape such as a bar graph, or a shape imitating a container such as a kettle, a beaker, a plastic tank, or a barrel may be used. Moreover, you may make it show with the number of lighting of a dot. Further, the capacity of the first scale and the current capacity in the first scale may be displayed numerically together with the variation image.

In the eighteenth means, in addition to any of the fifth to thirteenth and seventeenth means, the gist is that the first scale object is a container object.
If the container object means such a quantitative scale, it is possible to make the user feel more that fuel is consumed.

In the nineteenth means, in addition to any one of the seventeenth and eighteenth means, the control means displays the first scale object in a color different from the background color of the object. .
This also improves the visibility of the first scale object.

In the twentieth means, in addition to any of the seventeenth to nineteenth means, the control means causes the display means to display a past fuel consumption history, and the first scale object is accompanied by a constant fuel consumption. In addition, a display is made to return to the initial display state before the start of variation, and the constant fuel consumed this time is linked to the initial display state of the first scale object in the past fuel consumption history. The gist is that they are integrated and displayed.
As a result, the user sees that the first scale object repeats the increase and decrease of the scale corresponding to a certain consumption amount as the fuel is consumed, so that the operation and the fuel consumption are linked. Therefore, we will try to make ecological driving while avoiding driving that consumes fuel wastefully. Furthermore, since the display corresponding to the consumed fuel displayed by the increase / decrease of the first scale object is appropriately added to the past fuel consumption history and displayed, the user can visually check how much the fuel has been consumed in the past. Therefore, the relationship between driving and fuel consumption will be better understood.
Here, the “past fuel consumption history” may be the fuel consumption history from the most recent engine start to the present, or the total fuel consumption history since the electronic system of the present invention was installed in the vehicle. Alternatively, it may be a total fuel consumption history since the start of traveling of the vehicle. If the past fuel consumption history is the total fuel consumption history since the start of travel of the vehicle, the travel distance data is obtained from the vehicle when the electronic system of the present invention is attached to the vehicle, and this is used as the current average fuel consumption. Based on this, it is conceivable to calculate the fuel used, calculate a past fuel consumption history as a reference, and use it as an initial value. Further, the display mode of the past fuel consumption history may be a variation image or may be displayed numerically.

In the twenty-first means, in addition to any one of the seventeenth to nineteenth means, the control means restores the first scale object to the initial display state before the start of fluctuation with a constant fuel consumption. And displaying the second scale object having a larger scale unit than the first scale object that fluctuates in either the increasing or decreasing direction on the display means, and the first scale object is in an initial display state. When the operation is performed so that the second scale object is restored, the second scale object is displayed with a fluctuation amount corresponding to the constant fuel consumed this time in conjunction with the return operation.
As a result, the user sees that the first scale object repeats the increase and decrease of the scale corresponding to a certain consumption amount as the fuel is consumed, so that the operation and the fuel consumption are linked. Therefore, we will try to make ecological driving while avoiding driving that consumes fuel wastefully. Furthermore, since the display corresponding to the consumed fuel displayed by the increase / decrease of the first scale object is displayed by being integrated with the second scale object having a large scale unit, the user can also see how much the user has consumed in the past. Will be visually observed, and will better understand the relationship between operation and fuel consumption.
Here, the shape of the “second scale object” is not particularly limited as long as the variation is quantitative in either the increase or decrease direction. An obvious scale shape such as a bar graph, or a shape imitating a container such as a kettle, a beaker, a plastic tank, or a barrel may be used. Moreover, you may make it show with the number of lighting of a dot. Further, the capacity of the second scale and the current capacity in the second scale may be displayed numerically together with the variation image.

In the twenty-second means, in addition to the twenty-first means, the control means displays the past fuel consumption history on the display means, and the first and second scale objects are changed before the start of change as the engine stops. The gist of the present invention is to operate so as to return to the initial display state and to display the fuel consumption amount from the most recent engine start to the engine stop by integrating the past fuel consumption history.
As a result, the fluctuation image of the first and second scale objects is restored to the initial display state before the fluctuation start every time the engine is started and stopped every time the engine is started. The amount of fuel consumed until the engine is stopped is displayed to the user via the first and second scale objects, and the fuel consumption state for each operation is very easy to understand. Furthermore, since the display corresponding to the consumed fuel displayed by the increase / decrease in the first and second scale objects is appropriately accumulated in the past fuel consumption history and displayed, the user can also see how much the past consumption has occurred. Will be visually observed, and will better understand the relationship between operation and fuel consumption.
Here, the “past fuel consumption history” may be a total fuel consumption history since the electronic system of the present invention was attached to the vehicle, or a total fuel consumption history since the vehicle started running. There may be. Further, the display mode of the past fuel consumption history may be a variation image or may be displayed numerically.

In the twenty-third means, in addition to the twenty-first means, the control means has a larger scale unit than the second scale object that fluctuates in either the increasing or decreasing direction on the display means. The third scale object is displayed, and when the engine is stopped, the first and second scale objects are operated so as to return to the initial display state before starting the change, and the fuel consumption from the latest engine start to the engine stop is performed. The gist is that the amount is integrated into the past fuel consumption history, and the third scale object is variably displayed with the variation corresponding to the fuel consumption.
As a result, the fluctuation image of the first and second scale objects is restored to the initial display state before the fluctuation start every time the engine is started and stopped every time the engine is started. The amount of fuel consumed until the engine is stopped is displayed to the user via the first and second scale objects, and the fuel consumption state for each operation is very easy to understand. Furthermore, since the display corresponding to the consumed fuel displayed by the increase / decrease of the first and second scale objects is displayed by being integrated with the second scale object having a large scale unit, how much consumption has occurred in the past. At the same time, the user will visually observe and understand the relationship between operation and fuel consumption.
Here, the shape of the “third scale object” is not particularly limited as long as the variation is quantitative in either the increase or decrease direction. It may be a clear scale shape such as a bar graph, or a shape imitating a container such as a kettle, a beaker, a plastic tank, or a barrel. Moreover, you may make it show with the number of lighting of a dot. Further, the capacity of the third scale and the current capacity in the second scale may be displayed numerically together with the variation image.

In the twenty-fourth means, in addition to any one of the twenty-first to twenty-third means, the maximum fluctuation amount of the second scale object corresponds to the maximum fuel consumption from engine start to engine stop. And
The maximum fuel consumption from the engine start to the engine stop is a so-called full tank in the fuel tank. This is because, if the scale unit of the second scale object is too small, the second scale object fluctuates too quickly, so that the second scale object is preferably a scale unit corresponding to a sufficient consumption amount. For example, a scale of about 30 to 100 liters (L) is assumed.
In the twenty-fifth means, in addition to any one of the first to twenty-fourth means, the maximum variation amount of the second scale object is changed according to the fuel tank capacity of the vehicle.
For example, some vehicles have poor fuel consumption such as trucks and have a very large fuel tank capacity, while others have relatively small fuel tank capacities such as mini cars. For this reason, it is desirable to appropriately set the scale unit according to the vehicle type. This can be realized by setting the scale of the second scale object optimally by the control means based on the information if the vehicle type can electrically sense the full tank in the fuel tank. Further, the user may input appropriately.

In the twenty-sixth means, in addition to any one of the seventeenth to twenty-fifth means, the fluctuation display is performed by either increasing the area or decreasing the area in conjunction with the consumption of the fuel. The gist is to display any one scale object.
This is an image in which the bar width of the bar graph is widened, and the visibility of the first scale object is further improved.

In the twenty-seventh means, in addition to any one of the first to twenty-sixth means, the display means displays the fuel consumption from the current engine start time to the current time as numerical information together with the change display. The gist.
As a result, at least the fuel consumption amount from the current engine start time to the current time point is displayed as a numerical value, so that the user can obtain more accurate information on fuel consumption together with image information such as fluctuation display. .
In the twenty-eighth means, in addition to any one of the first to twenty-seventh means, the display means displays at least one information of the fuel flow rate, the instantaneous fuel efficiency, and the average fuel efficiency as a numerical value together with the change display. To do.
As a result, at least one piece of information on at least fuel flow rate, instantaneous fuel consumption, and average fuel consumption is displayed as a numerical value. Therefore, the user must obtain more accurate information on these fuel consumptions together with imaginary information such as fluctuation display. Can do.
The gist of the twenty-ninth means is a program for causing a computer to realize the function of the control means in the electronic system according to any one of the first to twenty-eighth means.

  According to the present invention, the user can grasp the state of fuel consumption in real time by visually observing the fluctuation display displayed on the display means, and can realize how much fuel is actually consumed. For this reason, it is necessary to keep ecological driving while avoiding useless fuel consumption.

FIG. 1 is an external perspective view of a fuel consumption display device 10 as an electronic system (electronic device). The fuel consumption display device 10 has a mechanism housed in a substantially rectangular parallelepiped casing 11 serving as a main body, and is fixed in a vehicle, for example, on a dashboard via a mounting bracket 12.
A display unit 14 forming a part of display means is exposed in a frame-shaped front frame 13 disposed on the front surface of the housing 11 (surface facing the driver). In the present embodiment, the display unit 14 is composed of a small 2.4 inch liquid crystal display. The display unit 14 also serves as a touch panel as input means. A slot 15 for inserting an SD card as a storage medium is formed on the side surface of the housing 11. A main cable 17 extends from the rear surface of the housing 11 (the surface facing the front window). As shown in FIG. 2, a female connector 18 is fixed to the tip of the main cable 17. A power switch (not shown) is formed on the rear surface of the housing 11.
As shown in FIG. 2, the fuel consumption display device 10 is connected to a vehicle diagnostic connector 22 having a front shape as shown in FIG. 3 via a connection adapter 21. The vehicle diagnostic connector 22 is disposed at a predetermined position (not constant depending on the vehicle type) that does not interfere with driving in the vehicle. The connection adapter 21 has a male connector 24 and a connection connector 25 at both ends of the connection cable 23. A female connector 18 and a male connector 24 at the tip of the main cable 17 extending from the fuel consumption display device 10 are connected, and a connection connector 25 is connected to a vehicle diagnosis connector 22 installed on the vehicle side. In the present embodiment, the fuel consumption display device 10 obtains power from the IGN signal terminal in the vehicle diagnostic connector 22, but a DC power jack is provided to obtain power from a cigar socket, for example. It is also possible.

Next, the electrical configuration inside the housing 11 of the fuel consumption display device 10 will be described based on the block diagram of FIG. In addition, about the structure which is not directly related to this invention, it abbreviate | omits.
The display unit 14 and the memory card reader 27 are connected to the controller MC as a control means.
The controller MC includes a known CPU, a memory such as a ROM and a RAM, a timer, and the like. Various types of vehicle information output from the vehicle diagnosis connector 22 is arbitrarily acquired in the ROM of the controller MC, and calculation of fuel flow rate, instantaneous fuel consumption, average fuel consumption, fuel consumption, accumulated fuel use, etc. is executed based on the information. A fuel consumption calculation program, a fuel consumption display program for displaying the calculated result on the display unit 14, a variable display program for variably displaying a predetermined object on the display unit 14, a change in average fuel consumption or average fuel flow rate A variable display change program for changing a variable display mode of a predetermined object, various programs such as an OS (Operation System), object data to be displayed on the display unit 14, master image data, various font data to be displayed on the display unit 14, and the like are stored. Has been. In the RAM, various vehicle information acquired from the vehicle diagnosis connector 22 and calculated values calculated by the calculation program such as the fuel consumption are stored.
The controller MC converts the vehicle information output to the K line or CAN of the vehicle diagnosis connector 22 on the vehicle side via the interface 28 into a processable communication protocol, for example, a UART signal.

In such an electrical configuration, the controller MC outputs a command to the terminal of the K line or CAN of the vehicle diagnosis connector 22 using a predetermined protocol, acquires predetermined vehicle information via the K line or CAN, and calculates the fuel flow rate, instantaneous When calculation is necessary for fuel consumption, average fuel consumption, accumulated fuel consumption per driving, and accumulated fuel consumption of past driving, they are calculated and acquired.
There are several means for obtaining the fuel flow rate. First, when a fuel consumption value is periodically output from the vehicle side, the value is used as it is. On the other hand, when the value of the regular fuel consumption cannot be obtained, it can be calculated by a known method based on either the intake air amount or the injection injection time at a fixed sampling time. In this embodiment, the injection injection time is used. Although the sampling time is arbitrary, it is 1 second here.
The injection injection time (valve opening time) can be calculated by giving a predetermined correction value to the output of the air flow meter (the air flow rate of the intake duct) and the engine speed, and performing various predetermined corrections. This corrected fuel flow rate is taken as fuel consumption. The fuel flow rate for 1 second corresponding to the sampling time is taken as the acquired fuel flow rate Bp. By dividing the integrated value of the acquired fuel flow rate Bp at a predetermined time by that time, the average fuel flow rate Hp within that time can be calculated.
First, when the instantaneous fuel consumption is periodically output from the vehicle side, the value is used as it is. If it cannot be obtained, the travel distance is calculated from the speed and travel time of the vehicle at a fixed sampling time, divided by the fuel flow rate, and calculated by giving a correction value. The vehicle speed is obtained from the vehicle diagnosis connector 22 described above, and the time is obtained from a known timer attached to the controller MC. Alternatively, similar to the above, it may be calculated by giving a predetermined correction value to the output of the air flow meter and the engine speed, and performing various predetermined corrections. The average fuel consumption is calculated from the accumulated instantaneous fuel consumption and travel time. The controller MC calculates the average fuel consumption in the time from the start of the engine to the present time.
The accumulated fuel consumption amount ΔPc of this operation is calculated by integrating the acquired fuel flow rate Bp from the start to the stop of the engine.
The accumulated fuel consumption Pcc of past driving is calculated by integrating all the acquired fuel flow rates Bp from when the fuel consumption display device 10 was attached to the vehicle until the previous engine stop.

Next, the layout of the display unit 14 whose display is controlled by the controller MC will be described with reference to FIGS. The controller MC synthesizes various objects and numerical values on the master image stored in the ROM and displays them in a variable manner. The liquid crystal display of the display unit 14 generally displays characters and objects having saturation and lightness on a black background. However, in the present embodiment, for the convenience of illustration, the background is shown in white, and the characters and objects are displayed. It shall be expressed by black or hatch lines.
As shown in FIGS. 5 to 8, a container object and a graduated cylinder object 31 as a first scale object are arranged near the right end of the display unit 14. A heel object 32 as a liquid object is disposed at an upper position in the graduated cylinder object 31. A total of ten tank objects 33 as second scale objects having the same shape are arranged at five positions on the left side adjacent to the graduated cylinder object 31 in parallel in the vertical direction.
In the first area 34 above the graduated cylinder object 31 and the tank object 33, the characters “currently used fuel” are arranged, and the numerical value (ml unit) of the accumulated fuel consumption ΔPc from the current engine start to the present time is arranged. it's shown.
On the left side of the display unit 14 is disposed a stacked object 36 in which a large number of block objects 35 as third scale objects are stacked. In the second area 37 above the stacked object 36, the word “accumulated fuel” is arranged so that the accumulated fuel consumption ΔPc of the accumulated fuel consumption display device 10 is displayed in numerical liters (L). Yes.
In the third area 38 at the center of the display unit 14, characters “fuel flow rate”, “instantaneous fuel consumption”, and “average fuel consumption” are arranged in order from the top, and numerical values corresponding to these are displayed. .

Next, details of the graduated cylinder object 31, the saddle object 32, the tank object 33, and the block object 35 (laminated object 36) on the display unit 14, particularly the variation contents will be described.
The graduated cylinder object 31 is a container-shaped object with an upper opening, and has a graduation line with a full state of 10. As the fuel is consumed, the liquid in the graduated cylinder object 31 increases the image of fuel, and the moving image changes so that the liquid level rises. Furthermore, when the liquid level reaches the full tank position, the liquid disappears instantaneously and becomes a colored state. A video that repeats this empty to full state is displayed.
In this embodiment, the capacity of the graduated cylinder object 31, that is, the default fuel consumption corresponding to the amount of change from empty to full is set to 100 ml. However, as will be described later, this set value can be changed. This default fuel consumption amount is assumed to be an amount consumed by a vehicle with a predetermined fuel consumption in about 2 minutes with fuel consumption only in an idling state. In normal driving, the fuel consumption is two to three times the fuel consumption in the idling state, so that the liquid level of the liquid moving image of the graduated cylinder object 31 reaches the full tank position in approximately several tens of seconds. This is a variation such that the scale of the graduated cylinder object 31 rises at an appropriate speed when visually observed by the user.
The controller MC displays a color state on the graduated cylinder object 31 as an initial screen when the engine has not yet started. Then, the liquid moving image in which the liquid level rises by the amount of increase corresponding to the fuel consumption is changed. The controller MC performs control so as to raise the liquid level in an amount corresponding to the acquired fuel flow rate Bp acquired at a timing of every second. Specifically, if the reference fuel flow rate is Bp1, and the liquid level height data (for example, 30 mm on the screen) when the liquid level of the graduated cylinder object 31 is full is N1, the controller MC uses this Bp1 for 1 second. The amount of increase H1 of the liquid level that is raised every time can be expressed by the following equation.
H1 = (N1 · Bp1) / 100
That is, when the acquired fuel flow rate Bp is 0, for example, before the cell motor is driven and the key is located at the ACC power-on position, the graduated cylinder object 31 remains in the empty state. . However, once the cell motor is driven and at least in the idling state, the acquired fuel flow rate Bp can be acquired. Therefore, the controller MC changes the moving image such that the liquid level rises according to the above formula.
When the liquid level reaches the upper end of the graduated cylinder object 31, the controller MC changes the liquid moving image to disappear and return to the initial screen of the color. Further, the controller MC once clears the display of the graduated cylinder object 31 with the stop of the engine, and starts the change again from the initial screen of the color at the next engine start.
In this embodiment, the rising liquid moving image is displayed in red as a caution color for arousing suppression of fuel consumption. However, the color is not particularly limited to red as long as it is a conspicuous color with respect to the background.

Next, the eyelid object 32 will be described. The controller MC does not display the soot object 32 on the display unit 14 at the stage where the engine has not yet started, but displays it along with fuel consumption.
The heel object 32 is a bar-shaped object that appears from above the graduated cylinder object 31 at different timings. The controller MC holds the heel object 32 at a random position in the width direction of the graduated cylinder object 31 at a predetermined length. It is lowered (flowed down) and changed so as to collide with the bottom surface or liquid surface of the graduated cylinder object 31 and disappear. As the liquid level of the graduated cylinder object 31 rises, the descending distance gradually decreases, and a moving image is formed such that the liquid level is integrated with the liquid level almost simultaneously with the appearance near the upper end of the graduated cylinder object 31.
In the present embodiment, the controller MC causes the number of soot objects 32 corresponding to the acquired fuel flow rate Bp to appear at different timings every second and at random positions in the width direction. In the present embodiment, for example, the bag object 32 is set to be filed according to the table shown in FIG. 9A by default. For example, if the average fuel flow rate Hp is 125 ml / m and the acquired fuel flow rate Bp is 1.1 to 2.5 ml / s, the two soot objects 32 appear in one second. However, as will be described later, this set value can be changed by the average fuel flow rate Hp or the like. In this embodiment, the soot object 32 is displayed in red as a caution color for arousing suppression of fuel consumption, and in order to cooperate with the liquid animation of the graduated cylinder object 31, but it should be a conspicuous color with respect to the background. It is not limited to red.

Next, the tank object 33 will be described. The tank object 33 has a scale unit larger than that of the graduated cylinder object 31, and like the graduated cylinder object 31, the liquid that images the fuel increases in the tank object 33 and the moving image changes such that the liquid level rises. Since the fluctuation of the tank object 33 is linked with the fluctuation of the graduated cylinder object 31, the controller MC returns the liquid level of the graduated cylinder object 31 to the full tank position and returns to the initial screen of the color. A liquid moving image in which the liquid level rises in units corresponding to 100 ml is displayed on the tank object 33.
The change display of the tank object 33 is executed as follows. As the fuel is consumed, the controller MC causes the tank object 33 to fill up from the lowermost right side of the two tank objects 33 (the graduated cylinder object 31 side) so that the liquid that images the fuel rises in order. Then, when the lower tank object 33 becomes full, such as the left tank object 33 → the upper right tank object 33, the upper tank object 33 is changed in order.
The capacity (fuel consumption corresponding to the fluctuation amount) of one tank object 33 in the present embodiment is set to 5 liters (L) by default. Therefore, any tank object 33 is 5 L = 5000 ml and 5000 ÷ 100 = 50, and the liquid level rises 50 times corresponding to the vertical movement of the graduated cylinder object 31 50 times. It becomes a state. In other words, the amount H2 of increase in the liquid level of the tank object 33 that is raised each time the controller MC returns the graduated cylinder object 31 to the initial state can be expressed by the following equation where the height of the tank object 33 is N2.
H2 = N2 / 50
In the present embodiment, since there are ten tank objects 33 that can store up to 5L, it is possible to express 50L of fuel consumption. This number can be changed as appropriate. Further, as will be described later, the capacity of each tank object 33 can be changed. The controller MC once clears the display of all the tank objects 33 as the engine is stopped, and starts the change again from the initial screen of the rightmost lowermost color at the next engine start.

Next, the stacked object 36 and the block object 35 will be described. The stacked object 36 is an aggregate of 20 rectangular blocks and 10 rectangular block objects 35 which are larger in scale unit than the tank object 33. Although the block object 35 is a small shape, the block object 35 is a change object that changes like a tank object 33 such that the liquid that imagines fuel rises. One block object 35 indicates an amount corresponding to 50L. Therefore, it is possible to express a fuel consumption of 10,000 L. A numerical value indicating the integrated value is also written every 2000L. This number can be changed as appropriate. Further, as will be described later, the capacity of each block object 35 can be changed.
The controller MC changes the stacked object 36 (block object 35) in accordance with the past accumulated fuel consumption amount Pcc. The fluctuation of the stacked object 36 (block object 35) is linked with the fluctuation of the tank object 33 and the graduated cylinder object 31, and the total fuel consumption of the tank object 33 and the graduated cylinder object 31 is cleared when the engine is stopped. Then, the accumulated fuel consumption amount ΔPc of the current operation is newly added to the past accumulated fuel consumption amount Pcc. Therefore, the stacked object 36 (block object 35) does not change in real time during the operation of the vehicle, but displays a new accumulated fuel consumption Pcc different from the previous one at the next engine start after the engine is stopped. Shown as an embodiment.
A more specific variation method of the block object 35 will be described. As described above, the controller MC causes the stacked object 36 (block object 35) to display a display reflecting the accumulated fuel consumption amount Pcc obtained by adding the fuel consumption from the latest engine start to the engine stop. Here, the block object 35 indicates an amount corresponding to 50 L, but in the present embodiment, the liquid image is displayed in five stages in units of 10 L, and in this case, units of 10 L or less are discarded. For example, it is assumed that the integrated fuel consumption amount Pcc is 722L. In that case, 722 ÷ 50 = 14... That is, the 14 block objects 35 are displayed as full tanks, and the 15th is displayed for 22 L at the half end. At this time, 2L is discarded and only the liquid level corresponding to 20L is displayed. That is, the liquid image is displayed so that the liquid level is at a position 2/5 from the bottom of the height of the block object 35.
The display order, that is, the use order of the block object 35 is displayed in a full state from the lower left block object 35 toward the right, and when the column is used up, it moves to the upper stage and from the left block object 35 to the right. I will display the change toward the direction. In the present embodiment, the liquid image is displayed in red as a caution color for stimulating the suppression of fuel consumption. However, the liquid image is not particularly limited to red as long as it is a conspicuous color with respect to the background.

In the above, the default fuel consumption amount is set to 100 ml as the fuel consumption amount corresponding to the variation amount of the graduated cylinder object 31 from empty to full. However, the controller MC varies the capacity of the fuel consumption based on the average fuel flow rate Hp acquired from the vehicle. This is because, for example, when the fuel consumption per unit time is very large, the change from the graduated cylinder object 31 to the full tank is close instantaneously, or conversely, it is too fast and the fuel consumption is low. This is for solving the problem that the graduated cylinder object 31 does not move at all. Therefore, the average fuel flow rate Hp is acquired, and the change from the optimum color to the full tank is executed in accordance with the fuel consumption state. The controller MC calculates the average fuel flow rate Hp in a predetermined time (for example, the past 10 minutes), and based on the value, the fuel consumption corresponding to the amount of change from the color cylinder to the full tank of the graduated cylinder object 31 according to the table shown in FIG. Change the amount. The table values are merely examples, and other numerical values can be set.
In the above description, the number of soot objects 32 that appear in accordance with the acquired fuel flow rate Bp is FIG. 9A by default. However, the controller MC appropriately changes the number of appearances based on the average fuel flow rate Hp for a predetermined time (for example, the past 10 minutes). This is also the same as the above, and solves the problem that the moving image does not become an atmosphere such as “liquid falls down” when the fuel consumption is too small. That is, if the fuel consumption is high, the number of soot objects 32 to appear is reduced. Conversely, if the fuel consumption is low, the number of soot objects 32 is increased. The controller MC changes the number of spear objects 32 that appear in accordance with the tables shown in FIGS. The table values are merely examples, and other numerical values can be set.
In the above, the tank object 33 is set to a capacity (maximum storage amount) of 5 L by default. However, the controller MC varies the capacity based on the average fuel flow rate Hp acquired from the vehicle. This is because the tank object 33 wants to display the fuel tank capacity of the vehicle as a unit of the full tank of the tank object 33 as much as possible. Therefore, the capacity of the fuel tank of the vehicle type is determined from the average fuel flow rate Hp, and the tank object 33 is The optimal capacity is set. The controller MC calculates an average fuel flow rate Hp for a predetermined time (for example, the past 30 minutes), and changes the capacity based on the value according to the table shown in FIG. The table values are merely examples, and other numerical values can be set. In addition, when the tank capacity information can be acquired, the capacity may be changed based on the information.

Next, an example of a fuel consumption display routine executed by the controller MC will be described based on a flowchart.
First, the fuel consumption display main routine will be described with reference to FIG.
When the controller MC detects the ON state of the ACC power supply in step S1, the controller MC starts a display operation on the display unit 14. Specifically, the master image is displayed, and the accumulated fuel consumption Pcc up to the previous time is displayed as a numerical value in the second area 37, and the number of block objects corresponding to the numerical value (the half-minute portion is displayed in increments of 10L) The 35 liquid images are displayed in red from the lower side according to the display order.
When the controller MC detects the start of the engine from the engine speed in the fluctuation display subroutine in step S2, the controller MC starts the fluctuation display of the liquid moving image of the graduated cylinder object 31 and the soot object 32 in red on the display unit 14 according to the fuel consumption. .
Then, in step S3, the controller MC detects whether or not the engine is stopped from the engine speed. When the engine stop is detected, the fuel consumption from the start of the engine to the stop of the engine is added to the past accumulated fuel consumption Pcc. In step S4, the flag F set in step S2 is set to 0 as will be described later, and the main routine is terminated. On the other hand, if it is determined in step S3 that the engine is not stopped, the process proceeds to step S2.

Next, the variation display subroutine will be described with reference to FIG. In the present embodiment, the controller MC executes this subroutine at a timing of 1 second intervals.
In step S11, the controller MC causes the graduated cylinder object 31 and the saddle object 32 to display a predetermined variation according to the acquired fuel flow rate Bp acquired at the current timing. Next, in step S12, it is determined whether or not the flag F is 0. If the flag F is 0, a value obtained by adding the newly calculated acquired fuel flow rate Bp to the accumulated fuel consumption amount ΔPc since the engine start in step S13. Is 100 or more, that is, whether the default capacity 100 ml of the graduated cylinder object 31 is full. The flag F is set here for the following reason. The capacity of the graduated cylinder object 31 is 0 ml at the start of operation. However, when the obtained fuel flow rate Bp is added up and the tank reaches a full tank, there may be a case where the remainder does not become exactly 100 ml. Then, in order to display an accurate fuel consumption, the remainder needs to be used as a basis for the next integration. Therefore, the flag F is set in order to distinguish between the first full start of operation and the second and subsequent times. If the controller MC determines that the value (Pc + Bp) has not reached 100, the routine is once terminated.
On the other hand, if the controller MC determines that the value (Pc + Bp) is 100 or more in step S13, the controller MC causes the graduated cylinder object 31 to change the liquid moving image once in step S14, assuming that the tank is full. At the same time, the tank object 33 is displayed to raise the liquid moving image corresponding to 100 ml. Then, a residual T0 is calculated by subtracting 100 from the value (Pc + Bp) when reaching 100 ml in step S15, a flag is set to 1, and this residual T0 is stored. Step S15 is a process for setting the remainder of 100 or more as a base for integration up to the next 100 in consideration of the case where the integrated value is not 100 but 100 or more.
On the other hand, when the flag F is 1 in step S12, it is determined that the graduated cylinder object 31 has been filled once or more in the past, and in step S16, the residual T0 that is the previous remainder is determined. It is determined whether or not the value obtained by adding the newly calculated acquired fuel flow rate Bp is 100 or more. If the controller MC determines that the value (T0 + Bp) has not reached 100, the routine is once terminated.
On the other hand, if the controller MC determines that the value (T0 + Bp) is 100 or more in step S16, the controller MC makes the same fluctuation as in step S14 in step S17 because it is full. In step S18, a new residual T0 is calculated by subtracting 100 from the value (T0 + Bp) when 100 ml is reached, this residual T0 is stored, and the routine is temporarily terminated.

Next, the outline | summary of the various fluctuation | variation expand | deployed on the display part 14 of such a fuel consumption display apparatus 10 is demonstrated.
The user connects the fuel consumption display device 10 to the vehicle diagnostic connector 22 via the connection adapter 21 to display the current fuel consumption state as shown in FIGS. It is possible to grasp the consumption situation.
FIG. 5 shows the display unit 14 immediately after the start of traveling. A liquid moving image in which the liquid level has risen to about half (that is, 50 ml) is displayed on the graduated cylinder object 31. At this stage, there is no change in the tank object 33. Further, the accumulated fuel consumption Pcc up to the previous time is displayed on the stacked object 36 (block object 35).
FIG. 6 shows the display unit 14 at the stage where the vehicle has traveled for about one hour. For example, assuming that the average fuel flow rate Hp is 120 ml per minute, an extra 7.2 L is consumed, so the first tank object 33A is full and the second tank object 33B is currently changing.
FIG. 7 shows the display unit 14 in a state where the load is large at a certain timing. When the load is large, the fuel flow rate and the fuel consumption amount increase, and accordingly, the numerical value of the fuel flow rate displayed on the display unit 14 tends to increase, while the instantaneous fuel consumption value and the average fuel consumption value tend to decrease. In a state where the load is large, the soot object 32 is poured onto the liquid level of the graduated cylinder object 31 in large quantities due to the large fuel flow rate. At this time, the rising speed of the liquid level of the graduated cylinder object 31 is also increased.
FIG. 8 shows the display unit 14 in an idling state. The soot object 32 becomes a small amount and is poured onto the liquid surface of the graduated cylinder object 31. This amount of pouring is the smallest in this vehicle. At this time, the rising speed of the liquid level of the graduated cylinder object 31 is the slowest in this vehicle.

By configuring as described above, the following effects are exhibited in the present embodiment.
(1) Since the user visually observes the display unit 14 of the fuel consumption display device 10, the display corresponding to the fuel consumption by his / her driving is displayed in real time by the moving images of the graduated cylinder object 31 and the soot object 32. It is possible to understand well that fuel consumption is linked to fuel consumption, and to keep ecological driving ahead of driving that consumes fuel wastefully.
(2) Since the graduated cylinder object 31 has its shape and scale, it gives the user an image of consuming fuel every moment, and the heel object 32 is expressed by a moving image that falls into the graduated cylinder object 31. Therefore, since the moving image having a very strong impact as a whole is viewed, the psychological effect for driving ecologically is high.
(3) Since the rising speed of the liquid level of the graduated cylinder object 31 increases as the fuel consumption speed increases, the number of soot objects 32 also increases. I will try to drive properly.
(4) By attaching a tank object 33 having a large scale unit to the graduated cylinder object 31 that fluctuates with fuel consumption, the graduated cylinder object 31 is caused to move sensitively to the fuel consumption speed. Therefore, even if the screen is small, it is possible to make the user visually observe a moving image highlighting the impression that fuel consumption is sufficiently consumed.
(5) When the graduated cylinder object 31 becomes empty, the display corresponding to the amount is accumulated on the tank object 33 side, so that the fuel consumed by the operation can be simultaneously observed, and the real-time fuel in a short time This will help you understand not only the consumption of fuel but also the consumption of fuel through driving, and this will also contribute to ecological driving.
(6) The accumulated fuel consumption Pcc up to the previous time is displayed on the stacked object 36 (block object 35) by starting the engine anew, and how much fuel has been consumed so far Thus, the details of fuel consumption can be easily understood.
(7) Optimum state of fuel consumption corresponding to the amount of variation from the graduated cylinder object 31 to the full tank, the number of soot objects 32, and the maximum storage amount of the tank object 33 according to the average fuel flow rate Hp of the vehicle concerned Therefore, it is possible to provide a fluctuation screen that is most easily seen by the user.
(8) Accurate numerical values such as fuel consumption in this driving, current fuel flow rate, instantaneous fuel consumption, average fuel consumption, past accumulated fuel consumption Pcc, etc. are also displayed. Information.

The present invention may be embodied in the following manner.
In the above embodiment, the fuel consumption is represented by a moving image in which a liquid object such as the spear object 32 flows down and is stored in the graduated cylinder object 31. It may be a moving image in which liquid comes out of the container.
For example, as shown in FIG. 15, the fuel consumption state may be expressed in such a manner that there is no graduated cylinder object 31 and the saddle object 32 simply flows down from above and disappears. This is because it can be visually observed that the number of liquid objects and the density of fuel are consumed in real time. In the above embodiment, the fuel consumption once accumulated in the graduated cylinder object 31 is moved to the tank object 33 and displayed in a batch. In FIG. 15, the tank object 33 gradually disappears as the dredge object 32 disappears. A fluctuation that raises the liquid level of the liquid moving image is preferable.
In the above embodiment, the setting is such that the appearance number of the soot object 32 increases as the fuel consumption increases. However, the shape or color of the soot object 32 may be changed according to the fuel consumption. Is also possible.

In the above embodiment, “the fuel consumption corresponding to the amount of variation of the measuring cylinder object 31 from the color to the full tank”, “the number of dredging objects 32”, and “the maximum storage amount of the tank object 33” are the average fuel flow rate of the vehicle. Although it was automatically set to a suitable setting based on Hp, when the user operates the touch panel of the display unit 14, the fuel corresponding to the amount of change from the color of the graduated cylinder object 31 to the full tank in paragraph 0037 is displayed. “Consumption amount”, “Number of basket objects 32”, and “Maximum storage amount of tank object 33” may be set.
First, the setting of “a fuel consumption amount corresponding to a variation amount of the measuring cylinder object 31 from the color to the full tank (hereinafter simply referred to as a fuel consumption amount)” will be described.
The user touches the touch panel of the display unit 14 to select a desired menu screen in order from the upper hierarchy (FIGS. 14A and 14B). Then, the user selects and confirms the average fuel consumption (here, less than 5 to 15) corresponding to his / her vehicle as a default. Similarly, for “number of soot objects 32” and “maximum storage amount of tank object 33”, a target menu screen is selected from FIG. 14A, and the number of soot objects 32 corresponding to the average fuel consumption of the vehicle is selected. The maximum storage amount of the tank object 33 is selected. Also, numerical values may be input on the screen.
Note that the user's selection here is an automatic "fuel consumption corresponding to the amount of variation of the graduated cylinder object 31 from color to full" and "number of soot objects 32" as determined by the controller MC in paragraph 0037. , Priority may be given to setting the “maximum storage amount of the tank object 33”, and the judgment of the controller MC may be given priority as an initial set value.
In addition, when the user makes a selection, it may be set by touching the screen on the display unit 14 as described above, or the SD card may be taken out and input from a personal computer.

In the above embodiment, the fuel consumption corresponding to the amount of variation of the graduated cylinder object 31 from color to full, the number of soot objects 32 and the fuel consumption of the tank object 33 are automatically based on the average fuel flow rate Hp. Although the set values are changed, the set values may be automatically changed based on the average fuel consumption. Alternatively, the user may select either the average fuel consumption or the average fuel flow rate Hp.
In the above, the capacity of the graduated cylinder object 31, that is, the default fuel consumption corresponding to the fluctuation amount from the color to the full tank is set to 100 ml, and this amount is the fuel when the vehicle with the predetermined fuel consumption is only in the idling state. The amount consumed in about 2 minutes at the flow rate was assumed.
On the other hand, it is also possible to set the default fuel consumption corresponding to the fluctuation amount from empty to full to the amount consumed in a few seconds at the fuel flow rate (maximum fuel flow rate) during operation under a very heavy load. is there. If the vertical movement of the liquid level can be recognized in the state where the fuel is consumed most, the vertical movement of the liquid level can be changed with a gentler behavior even in the same second unit in the normal operation state. As a result, the user can surely visually recognize the vertical movement of the liquid level in any driving situation.

The shape and arrangement position of the graduated cylinder object 31 as the first scale object are not limited to the above. Of course other than the shape of the graduated cylinder.
The shape, number, and arrangement position of the tank object 33 as the second scale object are not limited to the above. Further, the order of the change display accompanying the fuel consumption, that is, which tank object 33 is changed from can be changed as appropriate.
The shape, number, and arrangement position of the stacked object 36 (block object 35) as the third scale object are not limited to the above. In addition, the order of the change display accompanying fuel consumption, that is, from which block object 35 the change is made can be changed as appropriate.
The stacked object 36 (block object 35) may be eliminated and only the value of the accumulated fuel consumption amount Pcc may be displayed.
The tank object 33 may be eliminated, and only the numerical value of the accumulated fuel consumption amount ΔPc from the current engine start may be displayed.

Although the fuel consumption display device 10 has been described in the above embodiment, the present invention may be applied to other electronic devices such as radar devices and navigation devices.
-You may display a mileage on the display part 14. FIG.
-You may display on the display part 14 the time from engine starting to the present.
The current time may be displayed on the display unit 14.
-The screen size of the display unit 14 can be changed.
In the above embodiment as the control means, the controller MC is disposed in the fuel consumption display device 10, but the main body including the controller MC is installed outside the vehicle, wirelessly transmits and receives data, and only the display means You may make it install in a vehicle.
In the above embodiment, the graduated cylinder object 31 and the tank object 33 are displayed on the display unit 14 two-dimensionally. However, the image is displayed on the display unit 14 three-dimensionally, that is, as an image having a depth. You may do it.
If the total travel distance of the vehicle can be acquired as information from the vehicle, when the fuel consumption display device 10 is attached, the accumulated fuel consumption Pcc from the travel distance and the average fuel consumption until the fuel consumption display device 10 is attached is calculated. By calculating, it is possible to display the integrated fuel consumption amount Pcc that takes into account not only after the fuel consumption display device 10 is attached but also between the start of traveling of the vehicle and the fuel consumption display device 10 is attached. .
-As long as vehicle information can be acquired, you may make it acquire information from output parts other than the connector 22 for vehicle diagnosis for ODB-II.

In the above embodiment, the graduated cylinder object 31 is displayed as the first scale object, the tank object 33 is displayed as the second scale object, and the stacked object 36 is displayed as the third scale object. Since the scale unit is considerably large between the object 31 and the tank object 33, another object corresponding to the fuel consumption from the intermediate engine start to stop may be displayed during this period.
As such a scale object, when the cycle from engine start to stop is relatively short, for example, a distance of about 5 to 20 km such as commuting to a company, shopping in a suburban shopping mall, picking up a child, etc. It is assumed that an object corresponding to the fuel consumption amount (hereinafter referred to as a short-distance fuel consumption object) is displayed. The new short-distance fuel consumption object may be used in addition to the three kinds of scale objects or used in place of the tank object 33.
In the above embodiment, the graduated cylinder object 31 is an object that constantly changes when the engine is driven, and the tank object 33 and the stacked object 36 do not always change, and change when other conditions are satisfied. It was something to do. However, when the measuring cylinder object 31, the tank object 33, the stacked object 36, or the short-distance fuel consumption object is displayed in the above, the display mode is such that these are constantly changed when the engine is driven. It is also possible.
-The present invention can be freely implemented in a modified form without departing from the spirit of the present invention.
