Description of the Related Art The fuel consumption rate (hereinafter referred to as fuel efficiency) of a vehicle is important as a cost for maintaining the vehicle, and has recently been discussed as a very important problem from the viewpoint of environmental protection. Have been. In particular, regarding fuel efficiency of trucks (lorries),
This has become a very important issue for companies that use trucks for transportation, since they have a significant effect on overall distribution costs. For these reasons, various companies have made various considerations, such as giving guidance to drivers driving trucks to improve fuel efficiency and purchasing devices that improve fuel efficiency.

[0003] By the way, the fuel efficiency is a traveling distance per unit fuel, and is usually calculated as a traveling distance per liter. Therefore, the fuel efficiency is calculated by dividing the traveling distance of the vehicle by the amount of fuel required to travel the traveling distance.
It can be obtained from two numerical values.

It is a feature. Here, the fixed data includes, for example, a vehicle type, a displacement, a weight, an engine type, an axle load, and the like. The flow data includes, for example, a load amount of a load, a traffic congestion state, and weather. , Temperature, heating time, cooling time, the degree of tire and tire wear, and the like. It should be noted that, in addition to these, the ratio of the travel time of the expressway or the travel time of the general road can also be mentioned. Further, to digitize the fixed data and the flow data means, for example, to assign a specific numerical value of “3” to an old vehicle and “1” to a new vehicle, Assuming that the vehicle is a truck, for example, if the truck is a 4-ton vehicle, the load is 3 tons when the load is 3 tons, and if the load is 1 ton, the load is 3 tons. Specifying a numerical value for each item, such as "1". Then, in the present invention, the added value obtained by adding a part or the whole of the value obtained by digitizing the fixed data or the flow data is multiplied by the value indicating the fuel efficiency using a computer, or added from the value indicating the fuel efficiency. The numerical value is divided, or the value indicating the fuel consumption and the added value are added, or the added value (or the value indicating the fuel consumption) is subtracted from the value indicating the fuel consumption (or from the added value).

A consumption fuel recording unit in which the amount is recorded, a fixed data recording unit in which fixed data such as a vehicle type of the vehicle is recorded, and a flow data recording unit in which flow data such as the load amount of the load loaded on the vehicle is recorded. , Data recording means for recording respective data, numerical value giving means for giving a numerical value corresponding to the recording data recorded in the fixed data recording section and the flow data recording section, and recording in the traveling distance recording section. Multiplied or divided by the divided value obtained by dividing the given value by the value recorded in the fuel consumption recording section, and the added value obtained by adding a part or all of the value given by the above-mentioned value providing section, or the division. Evaluation value calculating means for calculating an evaluation value by adding a value and the added numerical value or subtracting the divided numerical value and the added numerical value, an evaluation value display means for displaying an evaluation value by the evaluation value calculating means, It is characterized by comprising.

[0010] The second aspect of the invention comprises data recording means, numerical value assigning means, evaluation value calculating means, and evaluation value display means. The data recording unit includes a traveling distance recording unit that records a traveling distance of the vehicle;
A consumed fuel recording unit in which the amount of fuel required to travel the traveling distance recorded in the traveling distance recording unit is recorded; a fixed data recording unit in which fixed data such as a vehicle type of the vehicle is recorded; It is means for recording respective data in a flow data recording unit in which flow data such as the load amount of the loaded load is recorded. That is, the mileage recording unit records the mileage of the vehicle, records the amount of fuel required by the consumed fuel recording unit, records the fixed data in the fixed data recording unit,
This is means for recording flow data in the flow data recording unit.
This data recording means is performed by using a computer, and is performed by recording on a recording medium such as a hard disk constituting the computer or a recording medium mounted on the computer.

Further, the numerical value assigning means assigns a numerical value corresponding to the recording data recorded in the fixed data recording section and the flow data recording section. For example, when an old vehicle type is recorded in the fixed data recording unit, a numerical value “3” is added, and when it is a new vehicle, a numerical value “1” is added. Also, assuming that the vehicle is a truck,
For example, if the truck is a 4 ton car,
When the load amount of the load is recorded as 3 tons in the flow data recording unit, a numerical value “3” is added, and when the load amount is 1 ton, a numerical value “1” is added. The numerical values assigned to individual data recorded in the fixed data recording unit and the flow data recording unit should be set to low numerical values if they are advantageous data for evaluating fuel economy, In addition to the case where a high numerical value is given in the case of, a high numerical value may be given in the case of advantageous data, and a low numerical value may be given in the case of disadvantageous data. In any case, the numerical value assigned by the numerical value assigning means is converted into a numerical value by a method capable of performing differentiation in accordance with various data recorded in the fixed data recording section or the flow data recording section. Is fine.

[0012] The evaluation value calculating means may calculate a value obtained by dividing the numerical value recorded in the mileage recording unit by the numerical value recorded in the fuel consumption recording unit. The evaluation value is calculated by, for example, multiplying an addition value obtained by adding all or all of the parts. The evaluation value to be evaluated is calculated by the evaluation value calculating means. In addition, this evaluation value is a low numerical value when the numerical value given to each data by the above-described numerical value giving means is advantageous data for evaluating the fuel efficiency, and a low numerical value when it becomes disadvantageous data. Is a case where a high numerical value is given. When the above “multiplication of the added numerical values” is performed, a high numerical value is high as an evaluation and a low numerical value is low as an evaluation. On the other hand, the numerical value assigning means assigns a high numerical value when it becomes advantageous data, and a low numerical value when it becomes disadvantageous data. The numerical value is high for the evaluation, and if the numerical value is high, the evaluation is low. In addition, when “the added numerical value is divided”, the result is opposite to the above result. And the evaluation value by such means is displayed by the evaluation value display means. That is, the evaluation value is displayed on a display device connected to the computer. The display method or display mode displayed by the evaluation value display means is not only a method of displaying a specific evaluation value for a specific vehicle, but also a transition of a series of past evaluation values of the specific vehicle.

This includes a mode in which the information is displayed.

[0013] Even in the case of the second invention having such a configuration, since the value taking into account the fixed data and the flow data is calculated, it is possible to achieve extremely rationality and suitability, and the driver who drives the vehicle It is possible to give appropriate guidance and advice to, and to find out the cause. In particular, according to the present invention, since the evaluation value is displayed on the display device, it is possible to clearly understand the state of the fuel efficiency of the vehicle by the display method or mode, and the display is displayed as a past transition. In this case, it can be used as an effective source for studying the cause of the transition and future countermeasures based on this cause.

If the latest evaluation value exceeds or falls below a predetermined range by comparison, the warning display means indicates the fact. That is, if the average value of the past evaluation values is “540” and the latest evaluation value is “450”, the comparison value is “90”. If the preset range is "50", it exceeds this value, and the warning display means displays that fact. However, whether “exceeds” or “belows” depends on the method of calculating the evaluation value. That is, a value obtained by dividing the numerical value recorded in the mileage recording unit by the numerical value recorded in the fuel consumption recording unit (fuel efficiency) and a part or all of the numerical value given by the numerical value giving unit are added. There are various differences depending on whether multiplication, division, addition, or subtraction is performed on the two numerical values with the added numerical value. Therefore, regardless of which calculation method is used, if the latest evaluation value exceeds the average value of the past evaluation values and the fuel efficiency falls below a preset range, the warning display means sets

Detailed information of the clicked vehicle is displayed on the monitor 8 (step st9). The detailed data includes a table and / or a past mileage, an amount of consumed fuel, fixed data and flow data, a past evaluation value, an average of evaluation values, and the like for the vehicle.
Alternatively, it is displayed in a graph. Then, in step st10, it is determined whether or not printing is to be performed. If printing is to be performed, printing is performed in step st11.
In addition, when a plurality of vehicles are displayed in the vehicle list displayed in step st5, and when detailed data of each of the vehicles is to be displayed, such operations are repeated.
When the work such as printing is completed or it is not necessary, the close button is clicked (the description is omitted in the flowchart) and there is no vehicle in which the evaluation value has decreased by a predetermined ratio or more in step st4. If determined to be, the process proceeds to step st12.

In this step st12, as shown in FIG. 8, it is determined whether or not there is any vehicle whose target evaluation value set by the driver has not been achieved. Is displayed. In this case, the monitor 8 displays, for example, "The vehicles that have not achieved the target are as follows." And a list of the vehicle number, the department name, the driver's name, the latest evaluation value, and the target value. Is displayed. When the vehicle displayed on the list is clicked on the monitor 8 with a pointing device or the like, detailed data of the vehicle is displayed. Then, when such a list is displayed, it is determined in step st14 whether or not printing is to be performed, and if printing is to be performed, the list is printed by the printer 7 (step st15). If no print is made in step st14 (and if print is made), it is determined in step st16 whether or not a vehicle in the list is clicked, and if a specific vehicle is clicked (selected), The detailed information of the clicked vehicle is displayed on the monitor 8 (step s).
t17). This detailed data includes past mileage, fuel consumption, fixed and flow data,
Past evaluation values, average values of the evaluation values, and the like are displayed in a table and / or graph form. Then, step st18
In, it is determined whether or not to print, and if it is to be printed, it is printed in step st19. Note that when a plurality of vehicles are displayed in the vehicle list displayed in step st13, and when detailed data of each of the vehicles is to be displayed, such operations are repeated. If the work such as printing is completed or it is not necessary, it is determined that the close button is clicked (the description is omitted in the flowchart) and that there is no vehicle in which the target evaluation value has not been achieved in step st12. If so, the process proceeds to step st20.

In step st20, it is determined whether or not there is a vehicle whose evaluation value has decreased by a predetermined ratio or more and the target evaluation value set by the driver has not been achieved. If there is such a vehicle, the vehicle list is displayed in step st21, and if it is to be printed (step st22), it is printed (step st23).
As shown in FIG. 9, when a specific vehicle displayed in the vehicle list is clicked in the manner described above (step s).
At t24), detailed data of the vehicle is displayed (step st25). The detailed data of this vehicle is the same data as the data displayed in step st9 and step st17. Then, it is determined in step st26 whether or not the detailed data of the vehicle is to be printed. If the detailed data is to be printed (when an operation such as clicking a button for executing printing is performed), the detailed data is determined in step st27. Printed. Then, when the work such as printing is completed or it is not necessary, the close button is clicked (the description is omitted in the flowchart), if there is no corresponding vehicle in step st20, and the vehicle is selected in step st24. If not, the process proceeds to the operation content selection screen in step st28. In other words, in this system, even in a vehicle in which the above-described rate of decrease in the evaluation value exceeds a predetermined rate (a vehicle in which the fuel efficiency decreases at a predetermined rate), a vehicle in which the target evaluation value set by each driver is not achieved. Does not exist (when all target evaluation values have been achieved), step st
If it is determined in step 3 that the correct ID number and password have been input, this operation content selection screen is displayed on the monitor 8 in step st28. This operation content selection screen displays whether or not to input data, whether to display a list, whether to display a ranking list, whether or not the rate of decrease in the evaluation value exceeds a predetermined ratio, and whether or not the target evaluation value has not been achieved. Whether to display a list, whether to display a list in which the rate of decrease in the evaluation value exceeds a predetermined ratio and the target evaluation value has not been achieved, whether to change various set values, etc. A selection button (a site clicked by the pointing device) to be selected is displayed. Therefore, in this system, if there is a vehicle such that the rate of decrease in the evaluation value exceeds a predetermined ratio before the operation content selection screen is displayed on the monitor 8, the specific vehicle is automatically Is configured to be displayed.

When the operation content display screen is displayed as described above, then, as shown in FIG.
At t29, it is determined whether to input data.
That is, when the user clicks a button for inputting data using a pointing device or the like, it is then determined whether or not to input fixed data (step st30). If it is determined that fixed data is input, a fixed data input screen is displayed on the monitor 8 in step st31. This fixed data entry screen
For example, as shown in FIG. 5, the information is divided into items such as company outline, vehicle outline, vehicle attachment information, personnel information, etc. Each item includes a telephone number, a license plate (vehicle number), a total weight, an engine, and a total load capacity. And the like are provided. When various types of fixed data are input to the fixed data input screen, it is determined in step st33 whether to input flow data. It should be noted that, even if it is determined in step st30 that fixed data is not input, the process proceeds to step st33. If it is determined in step st33 that flow data is input, a flow data input screen is displayed in step st34. As the flow data input screen, for example, as shown in FIG. 6, three screens are alternatively displayed. That is, although the display on the flowchart is omitted, in step st32, when the fixed data is input (when the vehicle number is input), as shown in FIG. (B)
Alternatively, any flow data input screen shown in (C) is displayed in step st34. For example, for the vehicle specified by the vehicle number, on the fixed data input screen shown in FIG. 5, as the running content, "local vehicle", "high-speed regular vehicle", or "high-speed free vehicle" is input,
When "local vehicle" is input, the flow data input screen shown in FIG. 6A is input in step st34. On the other hand, when the process proceeds to step st33 without input on the fixed data input screen (when fixed data is input in the past), a screen for inputting the vehicle number is displayed on the monitor 8, and the vehicle number is displayed on this screen. Is input, a flow data input screen corresponding to the running content of the specific vehicle number is displayed in step st34. Although not shown in the flow data input screens shown in FIG. 6, the flow data input screens are also provided with a place for recording the daily mileage and the amount of fuel required for the mileage. ing. When each fixed data is input in step st32, the fixed data is recorded in the fixed data recording unit 12, and when flow data is input in step st35, the flow data is stored in the flow data recording unit 12. 13 is recorded.
In this embodiment, the data relating to the mileage and the data relating to the fuel consumption adopt a procedure of being entered on the flow data input screen, respectively. The data on the mileage is recorded in the mileage recording unit 10 and the data on the commercial fuel is recorded in the consumed fuel recording unit 11.

When the fixed data and the flow data are input or recorded, respectively, each data is digitized in step st36. The digitization means that a numerical value recorded in the digitizing basic data recording unit 15 is allocated to specific fixed data and flow data recorded in the above-described procedure. After such digitization, the evaluation value is calculated (step st37). In the present embodiment, the method of calculating the evaluation value is as follows. First, the numerical value indicating the mileage recorded as the flow data is divided by the numerical value indicating the amount of fuel required for the mileage. Rate) is calculated. In addition, the sum of the numerical values corresponding to the fixed data and the flow data is added to calculate the added numerical value. Then, the fuel consumption value and the added value are multiplied. The multiplied numerical value becomes the evaluation value. The method of calculating the evaluation value may be other than these methods,
The method is as described above. And step st
In 37, when such an evaluation value is calculated, the flow returns to step st29 again. By repeating such operations, evaluation values for each vehicle owned by the establishment 3 are calculated, and these evaluation values are stored in the evaluation value accumulating unit 17 for each vehicle.
Is accumulated in When a plurality of evaluation values stored in the evaluation value storage unit 17 are stored for a specific vehicle, the average value is automatically calculated, and the calculated average value is used as the average value storage unit. 18 is recorded.

If it is determined in step st29 that data has not been input, the process proceeds to step st38, as shown in FIG. 11, where it is determined whether or not to display a list. In
In step st39, it is determined whether or not to perform weekly display. If it is determined that weekly list display is to be performed, a weekly list is displayed (step st4).
0). The weekly list (the same as the monthly list and the yearly list described below) may be a weekly list of a specific vehicle. A list of all vehicles owned by each week (or month or year) may be used. Then, in step st41, it is determined whether or not to print this list.
At 2, the printer 7 is driven to print. If it is determined in step st41 that printing is not to be performed, the flow advances to step st43 to determine whether or not to display a graph. If it is determined that a graph is to be displayed, the monitor 8
The graph is displayed every week, and is printed when the user determines that it is necessary to print the graph (steps st45 and st46). The format of the graph display in step st44 is displayed as a pie chart, line graph, or bar graph. Note that the above step st3
When it is determined in step 9 that the list display is not performed every week and when it is determined that the graph display is not performed in step st43, the process proceeds to step st47 (see FIG. 12).

In step st47, it is determined whether or not to output the monthly list. If it is determined that the monthly list is to be output, the monthly list is displayed on the monitor 8 (step st48). ). If the user wants to print this list, the list is printed (steps st49 and st5).
0) Then, it is determined whether or not to display a graph (step st51). If a graph is displayed, the evaluation value for each month is displayed as a graph (step st52). When the graph is printed, the process proceeds to steps st53 and st54, and is printed. Further, when it is not determined that the monthly list is output in step st47, and in step st51
If it is determined in step st53 that no graph display is to be performed, and if it is determined in step st53 that printing is not to be performed, the process proceeds to step st55 (see FIG. 13), and the year list display, its printing, graph display, and its printing processes ( (Steps similar to those described above) (step st56)
... Step st62), and proceed to step st63 (see FIG. 14). In this step st63, it is determined whether or not to output (display) a list indicating how the evaluation values of the entire vehicle owned by the establishment 3 are changing, and it is determined that the comprehensive list is to be displayed. In this case, the comprehensive list is displayed on the monitor 8 in step st64. Subsequent procedures include steps st49 to st54 and step st57 described above.
The operation is performed in the same procedure as that from step st61 to step st61 (step st65... Step st70). In this embodiment, as a method of displaying a list,
The method of listing by week, month and year was adopted.
A method of listing by week, month, and year may be adopted.

When the ranking list displayed on the operation content selection screen is selected (step s)
At t71), it is determined whether to display the fuel efficiency ranking list as shown in FIG. 15 (step st7).
2). If it is determined that the fuel efficiency ranking list is to be displayed, the fuel efficiency ranking list is displayed in step st73. This fuel efficiency ranking list is based on the above fuel efficiency values (the values before the evaluation value is calculated) based on the establishment 3
Is a list ranked in all the vehicles possessed, and it is determined in step st74 whether or not the list is to be printed. If the list is to be printed, the list is printed by the printer 7 (step st75). If it is determined in step st72 that the fuel efficiency ranking list is not displayed, and if it is determined in step st74 that printing is not to be performed, it is determined in step st76 whether or not the evaluation value ranking list is displayed. When it is determined in step st76 that the ranking list is displayed, the ranking list of the evaluation values is displayed on the monitor 8. The ranking list of the evaluation values is a list in which all the vehicles owned by the establishment 3 are ranked based on the evaluation values calculated by the calculation method described above. Then, in step st78, it is determined whether or not this evaluation value ranking list is printed,
If it is determined that printing is to be performed, printing is performed by the printer 7 (step st79).

If it is determined in step st76 that the evaluation value ranking list is not to be displayed, or if it is determined in step st78 that printing is not to be performed, the rate of decrease in evaluation value is determined in step st80 (see FIG. 16). It is determined whether to display a ranking list that exceeds a preset ratio. Step st80
In step S81, if it is determined that the ranking list is to be displayed, the list is displayed in step st81. If printing is to be performed, the program 7 is driven to perform printing (step st83). Step st80
In the case where it is determined that the ranking list in which the rate of decrease in the evaluation value exceeds the preset rate is not displayed,
If it is determined in step st82 that printing is not to be performed, it is determined in step st84 whether or not to display a vehicle ranking list for which the target evaluation rate has not been achieved. If it is determined in step st84 that the ranking list is to be displayed, the ranking is displayed (step s84).
t85), whether or not to print the list is determined in step st8
If it is determined in step 6 that printing is to be performed, printing is performed in step st87. If it is determined in step st80 and step st84 that none of the ranking lists is displayed, the process proceeds to step st88 (see FIG. 17). In step st88, the list is displayed in step st81 and step st85.
It is determined whether or not to display a ranking list of vehicles to be displayed in the above. In this step st88,
If it is determined that the ranking list is to be displayed, the ranking list is displayed in step st89, and whether or not to print the ranking list is determined in step s89.
