Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This is a continuation application of the prior PCT application PCT/JP2011/068021, filed on Aug. 8, 2011, pending, which claims priority from a Japanese patent application No. 2010-177544, filed on Aug. 6, 2010, the entire content of which is incorporated herein by reference. 
     
    
     TECHNICAL FIELD 
       [0002]    The present invention relates to a vehicle evaluation apparatus, in particular, a vehicle evaluation apparatus that is effective in comparing and determining the economical advantages of a plurality of vehicles each of which is a candidate for a vehicle purchaser to purchase. 
       BACKGROUND 
       [0003]    There has been evaluation methods related to safe driving, evaluation methods related to ride quality, evaluation methods related to fuel consumption saving, methods for evaluating performance such as speed and steering, and the like, as vehicle evaluation methods. 
         [0004]    Recently, in warming problems and energy problems which are becoming obvious, fuel consumption and vehicle drive energy have drawn increasing attention. As a result, the prices of vehicles each designed for improving fuel efficiency and innovating vehicle drive energy are getting higher than before. In addition, the innovation and selection of vehicle drive energy make progress in each manufacturer, wherein vehicles in various drive energy modes, such as gasoline vehicles, hybrid vehicles, ethanol vehicles, and electric vehicles, are presented. In such circumstances, a perspective and an index are desired by vehicle purchasers, with which the cost effectiveness of those vehicles can be more clearly compared and examined, in the correlation between the prices of the abovementioned vehicles using various vehicle drive energy modes, and the fuel consumption and the drive energy consumption costs thereof. 
         [0005]    Technological developments for reducing discharge amount of heat-trapping gases and for further improving fuel efficiency are reflected in general to the price of a vehicle using said technology; therefore, the vehicle price becomes high. Meanwhile, when a vehicle is distributed, wherein the fuel efficiency thereof is improved and the drive energy cost thereof is low even with a high vehicle price, more detailed evaluation of pros and cons would be necessary for a vehicle purchaser to evaluate, in the relationship between the vehicle price, which is included in the initial cost of a vehicle, and the fuel consumption and drive energy cost, which are reflected to the running cost thereof. In other words, in the case of an electric vehicle, for example, the vehicle price is higher than existing gasoline vehicles, but the cost of electricity which is the drive energy for driving the vehicle is lower than the cost of the drive energy of a gasoline vehicle. Consequently, it is questioned what is an index with which it is possible to compare the cost effectiveness of an electric vehicle, of which the price is high but the drive energy price is low, with the cost effectiveness of a gasoline vehicle, for example. 
         [0006]    From this viewpoint, it would be important for the vehicle purchaser to compare/examine the relationship among the cost at the time of purchasing a vehicle, i.e., initial cost, the vehicle drive energy consumption cost which is a major part of the vehicle maintenance cost (running cost) thereof, and further, in the case of an electric vehicle comprising an electricity storing section capable of being charged as needed, the earning to be obtained by using the electricity storing section to an application other than driving the vehicle, with the relationships among other candidate vehicles for purchasing. There was no evaluation method from this viewpoint in existing vehicle evaluations. 
         [0007]    Provided are: a vehicle evaluation apparatus and a vehicle evaluation system, wherein when a vehicle purchaser newly purchases a vehicle, it is possible to calculate economical indexes for different vehicles, based on the relationship among the initial cost at the time of purchasing the vehicle, the vehicle drive energy consumption cost, which is a major part of the vehicle maintenance cost for everyday driving, and the purchaser planned vehicle running distance which is planned by the purchaser, thereby comparing the economical efficiencies of the vehicles by thus calculated indexes; and a vehicle evaluation apparatus and a vehicle evaluation system, wherein in a vehicle having an electricity storing section capable of being charged as needed, it is possible to calculate earning to be obtained by using the electricity storing section to an application other than driving the vehicle, thereby comparing the economical effectiveness of the vehicles by thus calculated indexes. 
         [0008]    In addition, the present invention presents an economical index for developmental technologies also to vehicle manufacturers, and the vehicle manufacturers would friendly compete with other vehicle manufactures in the pursuit of further technical innovation and cost effectiveness. As a result, vehicle purchasers would be able to enjoy continuous earning.

         [0023]    The present invention is effective, in particular, when a vehicle purchaser compares a vehicle with other candidate vehicles for purchasing, with respect the relationship between a cost for purchasing the vehicle, i.e., initial cost, and a drive energy consumption cost, which is a main part of maintenance cost necessary for everyday driving. 
         [0024]    It is possible to provide each of the vehicle evaluation apparatuses in the claims of the present invention as a vehicle evaluation system, and each of the vehicle evaluation systems therein as a vehicle evaluation apparatus. 
         [0025]    Embodiment 1 of the present invention is configured in such a manner as to comprise a portion for calculating the relationship between a price of a vehicle, a cost for purchasing the vehicle, or a cost obtained by adding a cost for maintaining the vehicle to the cost for purchasing the vehicle (hereinafter referred to as “cost of vehicle purchasing cost and the like”), and a fuel distance (distance to empty in km per unit drive energy, expressed in km/L, km/kWh or the like) that is expressed as the fuel efficiency of the vehicle. Note that the vehicle herein is applicable to any vehicle such as, for example, passenger car, truck, bus, bike, and electric vehicle, that runs on the ground. In addition, the vehicle herein is applicable to any machine such as airplane that flies on air using drive energy, and helicopter. Furthermore, the vehicle herein is applicable to any machine such as ship that runs on the sea using drive energy. Moreover, the vehicle herein is applicable to any instrument and machine, such as home electric appliance and factory machine, which operate using drive energy. 
         [0026]    The portion for calculating the relationship between the cost of vehicle purchasing cost and the like, and the fuel distance of the vehicle can express, as an evaluation value, the ratio of vehicle fuel efficiency relative to the vehicle price (the larger the value is, the higher the cost effectiveness is), by dividing the fuel efficiency of the vehicle with the cost of vehicle purchasing cost and the like, for example. 
         [0027]    The portion for calculating the relationship between the cost of vehicle purchasing cost and the like, and the fuel distance of the vehicle can express, as an evaluation value, the ratio of vehicle price relative to fuel charge for 1 km (the smaller the value is, the higher the cost effectiveness is), by dividing the cost of vehicle purchasing cost and the like with the fuel efficiency of the vehicle, for example. Any evaluation method other than these examples, which is based on the comparison of the cost of vehicle purchasing cost and the like, and the fuel efficiency of the vehicle, may be applicable. For example, an evaluation value calculated using a predetermined coefficient and the like, based on the cost of vehicle purchasing cost and the like, and the fuel efficiency of the vehicle, can be expressed as the evaluation value of the present invention. In other word, embodiment 1 of the present invention is characterized in comparing the cost of vehicle purchasing cost and the like, with the fuel efficiency of the vehicle, to evaluate vehicles. 
         [0028]    Here, vehicle purchase price, tax (registration fee, weight tax and the like), insurance fee (compulsory automotive liability insurance fee, voluntary automotive insurance fee and the like) and the like, for example, are listed as the cost for purchasing vehicle and the like. Meanwhile, repair cost, automotive inspection cost, other inspection cost, parking fee, road fee (highway tolls and the like), drive energy consumption cost (note that the drive energy consumption cost is separately categorized and handled in the present invention to be explained by the embodiment below or the like), scrap cost and the like are listed as the maintenance cost of a vehicle. However, since the purpose of the present invention is to compare/examine cost effectiveness among candidate vehicles, when purchasing a vehicle, a numerical value, such as parking fee, having small differences with those of other vehicles does not have to be an important evaluation item. 
         [0029]    In embodiment 1 of the present invention, the evaluation value of a vehicle is represented, as the most convenient method, by a value obtained by dividing the fuel distance of a vehicle with the price of the vehicle. 
         [0030]    In other words, the fuel distance of a vehicle is apprehended as the most important information representing the cost effectiveness of the vehicle, and vehicle evaluation is made possible by dividing the numerical value of said fuel efficiency by the price of the vehicle, with which comparison with the vehicles of other manufacturers is possible in terms of how much technological development fee is reflected on the price of the vehicle in order to increase cost effectiveness. For example, in the comparison of vehicles of different manufactures, when the fuel efficiency and price of an A Company vehicle are 20 km/L and 1,000,000 yen, respectively, and the fuel efficiency and price of a B Company vehicle are 20 km/L and 1,500,000 yen, respectively, the evaluation value of the A Company vehicle is 0.00002 and the evaluation value of the B Company vehicle is 0.000013, which leads to an evaluation in which the A Company vehicle having a higher numerical value has a higher fuel efficiency relative to price, than the B Company vehicle. 
         [0031]    In addition, it is also possible as stated above to evaluate a vehicle planned to purchase, by using the cost for purchasing vehicle and the like as a cost necessary for purchasing the vehicle, and dividing said necessary cost by the fuel distance of the vehicle. 
         [0032]    Embodiment 2 of the present invention is configured in such a manner to have a portion for calculating the relationship between a cost obtained by subtracting the predicted reselling price after use of a vehicle from a cost which is a price of the vehicle, a cost for purchasing the vehicle, or a cost obtained by adding a cost for maintaining the vehicle to the cost for purchasing the vehicle (hereinafter referred to as “cost for purchasing vehicle and the like”), and the fuel distance that is expressed as the fuel efficiency of the vehicle. 
         [0033]    In embodiment 2 of the present invention, a cost element is set in addition to the evaluation calculation element of embodiment 1 of the present invention, said cost element being obtained by subtracting the predicted reselling price after use of the vehicle from the cost for purchasing vehicle and the like. The payment amount of the vehicle purchaser substantially for purchasing the vehicle is made clearer with the cost element. 
         [0034]    It is possible to estimate a predicted reselling price after use of a vehicle according to, for example, the model, type and purchase price of the vehicle, a vehicle using-year predicted by a purchaser, a vehicle running distance planned by the purchaser, history such as accident and failure, and the like. In addition, there are services, nowadays also on websites, for estimating and providing a reselling price of a vehicle, and a predicted price may be obtained by using said services. Furthermore, the vehicle evaluation system of the present invention may independently and separately have a predicted reselling price calculating portion for calculating the predicted reselling price of a vehicle. It is possible to calculate a predicted reselling price after use of a vehicle by the predicted reselling price calculating portion, by setting, as calculation elements, the model, type, and purchase price of the vehicle, the vehicle using-year predicted by the purchaser, the vehicle running distance predicted by the purchaser, the history of accident and failure, and the like, for example. 
         [0035]    In embodiment 2 of the present invention, the portion for calculating the relationship between a cost obtained by subtracting a predicted reselling price after use of the vehicle from the cost for purchasing vehicle and the like, and the fuel efficiency of the vehicle, is configured in such a manner as to express said relationship as an evaluation value of the cost effectiveness of the vehicle, by dividing the fuel distance of the vehicle by a cost obtained by subtracting the predicted reselling price after use of the vehicle from the cost for purchasing vehicle and the like. The reason why said relationship can be utilized as an evaluation value of cost effectiveness, and a specific example of the method therefor are the same as those of the example disclosed in embodiment 1 of the present invention. 
         [0036]    In addition, embodiment 2 of the present invention is not limited to the calculation method mentioned here, but may be any other evaluation method as far as said evaluation method is based on comparing a cost obtained by subtracting a predicted reselling price after use of the vehicle from the cost for purchasing vehicle and the like, with the fuel distance of the vehicle. For example, a calculation method for calculating an evaluation value by setting or using a certain coefficient, based on the cost obtained by subtracting a predicted reselling price after use of the vehicle from the cost for purchasing vehicle and the like, and the fuel distance of the vehicle, can be expressed as the evaluation value of the present invention. 
         [0037]    Embodiment 3 of the present invention is configured in such a manner as to comprise a portion for calculating the relationship among: a cost obtained by subtracting a predicted reselling price after use of a vehicle from a price of the vehicle, a cost for purchasing the vehicle, or a cost obtained by adding a cost (excluding drive energy consumption cost) for maintaining the vehicle to the cost for purchasing the vehicle (hereinafter referred to as “cost for purchasing vehicle and the like”); the fuel distance of the vehicle; a cost per certain unit of drive energy (cost per liter of a fuel such as gasoline, ethanol and hydrogen, or a cost per kWh of electricity, when a fuel efficiency is expressed in km/L, km/kWh or the like, respectively) that represents the fuel efficiency of the vehicle; and a using/running distance, which is planned by a purchaser (user) of the vehicle, or a vehicle using day, which is planned by the purchaser of the vehicle. The “portion for calculating the relationship” is explained below. 
         [0038]    If the fuel efficiency of a vehicle using gasoline as the vehicle drive energy, for example, is 20 km/L, it portion that said vehicle can run an average distance of 20 km with 1 liter of gasoline; therefore, the cost per certain unit of drive energy, which represents the fuel efficiency of the vehicle, portion the price of 1 liter of gasoline for the vehicle that can run an average distance of 20 km per 1 liter of gasoline at the time of calculation, for example. In other words, if the price of 1 liter of gasoline at a certain time is 130 yen, 130 is the numerical amount value. 
         [0039]    In addition, there are various kinds of energy sources for driving a vehicle, such as gasoline (regular gasoline, high-octane gasoline, and the like), light oil, kerosene, gas, ethanol, hydrogen and electricity, but the cost per certain unit of drive energy for any energy source, which represents the fuel efficiency of the vehicle, is made possible to be set or inputted as a calculation item in the method for calculating the abovementioned relationship. For example, in the case where the fuel efficiency (electricity efficiency) is represented as 10 km/kWh, and electricity charge for 1 kWh is 22 yen, for example, the cost per certain unit of drive energy, which represents the fuel efficiency of the vehicle, is 22 (yen). 
         [0040]    The using/running distance of a vehicle, which is planned by a purchaser (user) of the vehicle, is explained below. The using/running distance of a vehicle, which is planned by a purchaser (user) of the vehicle, is a numerical value of predicted using/running distance of a candidate vehicle to be newly purchased. In order to set a using/running distance of the planned vehicle, a using/running distance of the vehicle to be purchased is predicted, for example, by considering the method for utilization (commuting, leisure, transportation, commercial and the like) of a vehicle that has been used in the past, and by confirming the running distance which the vehicle that has been used in the past has run, on the vehicle instrument thereof. Even a first-time vehicle purchaser can obtain a predicted using/running distance of a candidate vehicle to be purchase, by considering the method for utilization of the vehicle, using-year from now on, the using frequency (how many days a week, and how much distance to run per day), and the like. The planned using/running distance of the vehicle is configured in such a manner as to be substantially the same as those of other candidate vehicles to be compared with. 
         [0041]    The vehicle using day, which is planned by a purchaser of a vehicle, is a numerical value obtained by predicting the number of days in which a vehicle is planned to be used, from a time when the purchaser of a vehicle newly purchases the vehicle to a time when the vehicle purchaser relinquishes or scraps the vehicle. It is possible for the purchaser to predict said numerical value, from a similar viewpoint to the planned vehicle using/running distance. The vehicle using day, which is planned by the purchaser of the vehicle, is configured in such a manner as to be substantially the same as those of other candidate vehicles to be compared with. 
         [0042]    The “portion for calculating the relationship” in embodiment 3 of the present invention is configured, for example, in such a manner as to: multiply a numerical value obtained by dividing the vehicle using/running distance planned by a purchaser (user) of the vehicle, by the fuel distance (km) of the vehicle, with a cost per certain unit of drive energy, which represents the fuel efficiency of the vehicle; add the cost for purchasing vehicle and the like to thus obtained numerical value; subtract the predicted reselling price after use of the vehicle from thus obtained numerical value; and divide thus obtained numerical value by the vehicle using/running distance or vehicle using day, which are planned by the purchaser of the vehicle. Note that the calculation sequence is not limited to that indicated above, and any calculation method, which meets the intention of calculation method similar to the calculation method of the present invention, may be applicable. 
         [0043]    In addition, the invention as described in claims  12  and  13 , which discloses application models of embodiment 3 of the present invention, is configured, for example, in such a manner as to: multiply a numerical value obtained by dividing the vehicle using/running distance planned by a purchaser (user) of the vehicle by the fuel distance (km) of the vehicle, with a cost per certain unit of drive energy, which represents the fuel efficiency of the vehicle; add the cost for purchasing vehicle and the like to thus obtained numerical value; subtract the predicted reselling price after use of the vehicle from thus obtained numerical value; and divide thus obtained numerical value by the vehicle using/running distance or vehicle using day, which are planned by the purchaser of the vehicle. 
         [0044]    Embodiments of the present invention have been discussed so far, but the vehicle evaluation system of each of embodiments 1-3 may be configured in such a manner as to include a numerical value for evaluating the discharge amount of greenhouse gases. 
         [0045]    The discharge amount of greenhouse gases (mainly carbon dioxide) of a vehicle is determined by the drive energy type (fuel type) and the consumption amount thereof. For example, the calculating formula of a carbon dioxide emission coefficient for each drive energy type (fuel type) is expressed as: (CO 2  emission coefficient (kg-C/MJ))=(carbon content (kg-C/kg, kg-C/L or kg-C/Nm 3 ))/(unit calorific power (MJ/kg, MJ/L or MJ/Nm 3 )). In addition, a calculation formula of the discharge amount of carbon dioxide is expressed as, for example: (CO 2  discharge amount (kg-CO 2 ))=(fuel use (L))×(CO 2  emission coefficient (kg-CO 2 /L)). Accordingly, when a purchaser evaluates the discharge amount of carbon dioxide of a candidate vehicle for purchasing, the discharge amount of carbon dioxide thereof can be obtained by dividing the vehicle running distance planned by the purchaser, by the numerical value of the fuel efficiency of the vehicle, and by multiplying thus obtained numerical value with the discharge coefficient. It is possible to calculate and compare the discharge amounts of carbon dioxide of other vehicles, in a similar manner.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0052]    The system, as illustrated in  FIG. 1 , to which this invention is applied, is configured in such a manner as to: input a cost necessary for purchasing a vehicle, such as the cost for purchasing vehicle and the like; input/select the cost from a separately prepared database; or calculate, if needed, the cost based on data memorized in the database, in step  1  (S 1 ). Said step  1  is configured in such a manner as to, when using a database in such a manner as described above, for example, prepare the database for each vehicle model and each type, or calculate the database in a timely manner based on database information, and read, select and arrange, or automatically arrange the database. In addition, step  1  may be configured in such a manner as to, when using the database, read/select the cost for purchasing vehicle and the like, and the model and type of a vehicle that a purchaser plans to purchase by using a text retrieval function and the like. 
         [0053]    Step  2  (S 2 ) of  FIG. 1  is configured in such a manner as to calculate the evaluation value of the candidate vehicle by dividing the fuel distance of the vehicle by the numerical valued obtained by step  1 . 
         [0054]    The fuel distance of the vehicle, which is used in step  2 , is configured in such a manner as to be inputted or read/selected from a separately prepared database. 
         [0055]    The purpose of the processing in step  3  (S 3 ) of  FIG. 1  is explained below. In step  2  of  FIG. 1 , wherein the price of a candidate vehicle for purchasing is 1,000,000 yen and the fuel efficiency thereof is 20 km/L, for example, the value obtained by dividing 20 by 1,000,000 is 0.00002. Said value is hard to see for the purchaser, or is expected to be confusing, so that a processing for multiplying the numerical value with 100,000, for example, makes the value to be 2, which is friendly. Step  3  in  FIG. 1  does not change the evaluation value itself; therefore, it may be possible to skip said step  3  and step  4 , i.e. go from step  2  (S 2 ) to step  5  (S 5 ). 
         [0056]    A similar effect of step  3  of  FIG. 1  can be achieved by changing the fuel distance display in step  2 . In other words, when the purchase price of a candidate vehicle for purchasing is 1,000,000 yen and the fuel efficiency thereof is 20 km/L, the evaluation value is 0.02 or 2 by setting the fuel distance to be 20,000 m/L or 2,000,000 cm/L, respectively. It may be possible to automatically convert the value of fuel efficiency from km/L to m/L or cm/L, in step  2  of  FIG. 1 , in order to obtain said effect. 
         [0057]    If multiplying a constant value is selected in step  3  of  FIG. 1 , the process goes to step  4 . 
         [0058]    If multiplying a constant value is not selected in step  3  of  FIG. 1 , the process goes to step  5 . 
         [0059]    In addition, it may be possible to skip the processing of step  3  of  FIG. 1 , and automatically multiply a constant numerical value to the numerical value obtained in step  2 . In this case, the process goes from step  2  to step  4 . 
         [0060]    Step  4  of  FIG. 1  is configured in such a manner as to multiply the numerical value obtained in step  2  with a constant numerical value. 
         [0061]    Step  5  of  FIG. 1  is configured in such a manner as to display the numerical value obtained in step  4  or step  2 . 
         [0062]    The system of  FIG. 1  of the present invention is explained here. Said system may be a method for processing steps  1 - 5  in one apparatus (terminal), and presenting an evaluation, or may be a system in which steps  1 - 4  for calculating/processing an evaluation and step  5  for displaying calculated evaluation are connected to each other via a network, such as the Internet. In other words, said system may be configured in such a manner that calculating/processing in steps  1 - 4  is performed in a server apparatus and displaying in step  5  is performed in a terminal connected to the server apparatus via a network, for example. In the case of a system in which apparatuses are connected to each other via a network, the abovementioned terminal may be better to be configured in such a manner as to perform the start and input processing in each step. 
         [0063]    Next, the system, as illustrated in  FIG. 2 , to which this invention is applied, is a system in which a step of “inputting and/or calculating a cost obtained by subtracting a predicted reselling price after use of a vehicle from the cost obtained in step  1 ”, which serves as step  2  (S 2 ) of  FIG. 2 , is inserted in step  1  (S 1 ) and step  2  (S 2 ) on the system illustrated and explained in  FIG. 1 . 
         [0064]    It is possible as mentioned above to predict a predicted reselling price after use of the vehicle, which is inputted and/or calculated in step  2  in the system of  FIG. 2 , according to the model, type, purchase price of the vehicle, the vehicle using-year predicted by the purchaser, the vehicle using/running distance planned by the purchaser, the history of accident and failure, and the like. In addition, there are services on the website nowadays, each of which predicts and provides a reselling price of a vehicle so that a predicted cost may be obtained by using such services. Furthermore, the vehicle evaluation system of the present invention may independently and separately have a predicted reselling price calculating portion for calculating the predicted reselling price of a vehicle. It is possible to calculate the reselling price after use of a vehicle in the predicted reselling price calculating portion, by setting, as calculation elements, the model, type and purchase price of the vehicle, the vehicle using-year predicted by the purchaser, the vehicle using/running distance planned by the purchaser, the history of accident and failure, and the like, for example. 
         [0065]    Step  4  (S 4 ) and step  5  (S 5 ) in the system of  FIG. 2  of the invention intend to provide the same meaning and effect as those of step  3  (S 3 ) and step  4  (S 4 ) of  FIG. 1 , the explanation on which is omitted here. It may be possible to skip step  4  (S 4 ) and step  5  (S 5 ) of  FIG. 2 , and go from step  3  (S 3 ) to step  6  (S 6 ). In addition, the system in  FIG. 2  of the invention may process steps  1 - 5  in a server apparatus, and step  6  and start in a terminal apparatus connected to the server apparatus via a network, for example. 
         [0066]    A system, to which this invention is applied, in such a manner as illustrated in  FIG. 3 , is explained next. The flow of step  1  (S 1 ) and step  2  (S 2 ) of the system of  FIG. 3  is the same as the flow of step  1  (S 1 ) and step  2  (S 2 ) of the system of  FIG. 2  so that the explanation thereon is omitted. 
         [0067]    Step  3  of  FIG. 3  is configure in such a manner as to calculate a vehicle energy consumption cost in the case where a vehicle has run the vehicle running distance, which is planned by a purchaser (user) of the vehicle, and to add the calculated cost to the cost obtained in step  2 . 
         [0068]    The using/running distance of a vehicle, which is planned by the purchaser of the vehicle, is a numerical value of predicted using/running distance of a candidate vehicle to be newly purchased, as discussed previously. The planned vehicle using/running distance is configured to set by the purchaser of the vehicle, such as 20,000 km or 50,000 km, for example. 
         [0069]    When the vehicle using/running distance planned by the purchaser of the vehicle is set in such a manner as described above, the vehicle drive energy consumption cost in the case where the vehicle has run the vehicle running distance planned by the purchaser of the vehicle can be calculated as a predicted value by using the fuel distance of the candidate vehicle for purchasing, and the drive energy unit price (for example, price per 1 liter of gasoline, in the case of a gasoline vehicle) of the vehicle at the time of calculation. 
         [0070]    For example, the drive energy consumption cost is 325,000 (=50,000/20×130) yen, in the case where the vehicle has run the vehicle running distance planned by the purchaser of the vehicle, wherein the vehicle running distance planned by the purchaser of the vehicle is 50,000 km, the fuel efficiency thereof is 20 km/L, and the price of 1 liter of gasoline is 130 yen at the time of calculation, for example. 
         [0071]    Accordingly, in the calculating portion up to step  3  of  FIG. 3 , if the cost in step  1  is 1,500,000 yen, the cost in step  2  is 500,000, the vehicle running distance planned by a purchaser (user) is 50,000 km, the fuel efficiency of the vehicle is 20 km/L and the price of 1 liter of gasoline at the time of calculation is 130 yen, for example, the calculation result up to step  3  of  FIG. 3  is 1,325,000 (=1,500,000−500,000+325,000) yen (where 325,000 is previously led from 50,000/20×130). 
         [0072]    Step  4  is configured in such a manner as to divide the numerical value obtained in step  3  by the vehicle using/running distance planned by the purchaser (user) or the number of vehicle using days planned by the purchaser. 
         [0073]    In step  4 , if the cost in step  1  is 1,500,000 yen, the cost in step  2  is 500,000 yen, and the vehicle running distance planned by the purchaser is 50,000 km, the fuel efficiency is 20 km/L, and the price of 1 liter of gasoline is 130 yen at the time of calculation, the abovementioned quotient is obtained by dividing the numerical value obtained in step  3  by 50,000 km, i.e., (1,500,000−500,000+325,000)/5000=26.5. This numerical value is obtained by dividing the numerical value, which is obtained by adding the initial cost at the time of purchasing and the running cost of the vehicle, by the planned vehicle running distance, and is effective as a numerical value for evaluating the cost effectiveness of the vehicle for purchasing. The calculating method of the evaluation numerical value can be regarded as the cost per km of running distance when the purchaser uses said vehicle. 
         [0074]    In addition, in step  4 , if the cost in step  1  is 1,500,000 yen, the cost in step  2  is 500,000 yen, and the vehicle running distance planned by the purchaser is 50,000 km, the fuel efficiency is 20 km/L, the vehicle using day planned by the purchaser is 2,000 days, and the price of 1 liter of gasoline is 130 yen at the time of calculation, the abovementioned quotient is obtained by dividing the numerical value obtained in step  3  by 2,000 days, i.e., (1,500,000−500,000+325,000)/2000=662.5. The calculating method of the evaluation numerical value can be regarded as the cost for moving per day when the purchaser uses said vehicle. 
         [0075]    The steps after step  5  (S 5 ) of  FIG. 3  intend the same meaning and effect as those of the steps after step  3  (S 3 ) of  FIG. 1 , the explanation on which is omitted here. Accordingly, it may be possible to skip step  5  (S 5 ) and step  6  (S 6 ) of  FIG. 3 , and go from step  4  (S 4 ) to step  7  (S 7 ). In addition, a system such as the system of  FIG. 3 , to which this invention is applied, may process steps  1 - 5  in a server apparatus, for example, and step  7  and start in a terminal apparatus connected to said server apparatus via a network, for example, in such a manner as the systems in  FIG. 1  and  FIG. 2 . 
         [0076]    A system such as the system of  FIG. 4 , to which this invention is applied, is explained next. The vehicle identification information displaying portion is configured in such a manner that the vehicle identification information on each of a plurality of vehicles of respective vehicle manufacturers, such as model, type, vehicle type, vehicle weight, displacement, category, fuel efficiency, weight tax, and acquisition tax, is memorized or inputted by a purchaser (user) in said portion. The weight tax, replacement, category and the like, which are considered to be unnecessary for, in particular, comparing the cost effectiveness with other candidate vehicles for purchasing, are allowed to miss. The structure of an apparatus for storing information in the vehicle identification information displaying portion is configured with, for examples, memory media such as, hard disk drive, CD-ROM, DVD-ROM and BD-ROM, memories and the like. The storage method therein is configured in such a manner as to describe and store information as a table format. The information, for example, on a plurality of vehicles of the respective vehicle manufacturers to be stored in the vehicle identification information displaying portion may be configured in such a manner as to be designed and set based on the information that the respective vehicle manufacturers publish, based on the specification of Ministry of Land, Infrastructure, Transport and Tourism (MLIT). 
         [0077]    The information to be memorized or inputted in the vehicle identification displaying portion is configured in such a manner as to be read and selected, or inputted and selected in a timely and sequential manner, as an element for calculating an evaluation value of the vehicle, by an information reading/selecting portion to be described below. In addition, the information reading/selecting portion to be described below is configured in such a manner as to have, for example, a text retrieval function and a voice retrieval function, and retrieve, read and select vehicle identification information from the vehicle identification information displaying portion in which the vehicle identification information is memorized as a database, by the action of a user to input the model, type and vehicle type of a vehicle to examine to the information reading/selecting portion to be described below. 
         [0078]    A vehicle purchasing cost and the like displaying portion is configured in such a manner that the price of each of the plurality of vehicles of the respective vehicle manufactures, the cost for purchasing each of the plurality of vehicles, or the cost (hereinafter referred to as “cost for purchasing vehicle and the like”) obtained by adding the cost for maintaining (excluding drive energy consumption cost) each of the plurality of vehicles, is memorized or inputted by a purchaser. The cost for purchasing vehicle and the like is as mentioned above. The vehicle purchasing cost and the like displaying portion is configured with, for example, the abovementioned memory media and memories when storing the cost for purchasing vehicle and the like. 
         [0079]    In addition, when each of the vehicle identification information displaying portion and the vehicle purchasing cost and the like displaying portion stores each piece of information in each portion, the pieces of information of the same vehicle among the plurality of vehicles of the respective vehicle manufacturers are configured in such a manner as to be mutually linked information. In other words, for example, the items, such as the model, type, vehicle model of the vehicle identified by and stored in the vehicle identification information displaying portion, and one or plurality items, such as a unique identification number set for each vehicle, are configured in such a manner as to be contained in the information on the same vehicle in the vehicle purchasing cost and the like displaying portion, wherein the information in the vehicle identification information displaying portion, and the information in the vehicle purchasing cost and the like displaying portion can be linked as a database. Accordingly, when vehicle identification information on one vehicle is retrieved and read from the vehicle identification information displaying portion by the information reading/selecting portion to be described below, for example, the cost for purchasing vehicle and the like of the same vehicle as the one vehicle may be configured in such a manner as to be simultaneously read from or generated by the vehicle purchasing cost and the like displaying portion, by the information reading/selecting portion to be described below. 
         [0080]    Furthermore, in the information in the vehicle identification information displaying portion and the information in the vehicle purchasing cost and the like displaying portion, for example, multiple pieces of information on the same vehicle among the plurality of vehicles of the respective vehicle manufacturers can be linked as a hyperlink structure in items, such as vehicle model and unique identification number, in the information on said same vehicle. 
         [0081]    Moreover, in the information in the vehicle identification information displaying portion and the information in the vehicle purchasing cost and the like displaying portion, information on the same vehicle among the plurality of vehicles of the respective vehicle manufacturers may be configured in such a manner as to be programmed in advance using a programming language such as CGI (Common Gateway Interface), PHP (Hypertext Preprocessor) and JavaScript, in order to be simultaneously called as linked associated information. Note that, in the information in the vehicle identification information displaying portion and the information in the vehicle purchasing cost and the like displaying portion, the method for generating linked information from multiple pieces of information on the same vehicle among the plurality of vehicles of the respective vehicle manufacturers is not limited to the method mentioned here. In addition, in the “linked” relationship of vehicle identification information displaying portion with the vehicle purchasing cost and the like displaying portion, the cost for purchasing vehicle and the like stored in the vehicle purchasing cost and the like displaying portion may be stored in the vehicle purchasing cost and the like displaying portion as part of the information thereof. 
         [0082]    The purchaser planned vehicle running distance displaying portion is configured in such a manner that a purchaser planned vehicle running distance is memorized, memorized and calculated, or inputted therein. Here, an example in which a purchaser planned vehicle running distance is stored in a storage of a purchaser planned vehicle running distance displaying portion, is configured in such a manner as to set and store 1,000 km as the minimum numerical value, set and memorize numerical values obtained by extending said distance by 100 km in sequence in the storage unit, and set and memorize  100 , 000  km as the maximum numerical value, for example. The purchaser planned vehicle running distance displaying portion may also be configured in such a manner that a purchaser can read and select a numerical value memorized in the memory unit from said portion, by a pull-down displaying method in a hyper text markup language (html) format, for example. The minimum value, values obtained by extending the distance in sequence, and maximum value are not limited to the values disclosed here. When the purchaser planned vehicle running distance displaying portion memorizes, or memorizes and calculates, as described above, the structure of an apparatus for memorizing is configured with the abovementioned memory media and memories.

       INDUSTRIAL APPLICABILITY 
       [0120]    The present invention enables comparison/evaluation of the cost effectiveness of a vehicle by comparing mainly vehicle price, fuel efficiency, and energy consumption cost with those of other vehicles, promotes cost competition, function improvement, quality improvements and the like among vehicle manufactures, and, as a result, makes a contribution on creation of low carbon society, and benefit of purchasers. In addition, the present invention also provides, in a new way, comparison of a vehicle that a purchaser plans to purchase, which comprises an electricity storing section capable of being charged as needed, with other vehicles, wherein the earning that the purchaser of the vehicle obtains by using the electricity storing section in an application other than running the vehicle is predicted and calculated. 
         [0121]    Furthermore, the present invention can be used for evaluating electric/electronic apparatuses other than evaluating cost effectiveness of a vehicle. In other words, the research and development of electric/electronic apparatuses has been active for the creation of low carbon society, as well as vehicles, and it becomes important to compare how the cost used for the research and development is reflected to the price thereof, with how energy consumption is improved thereby as a result. 
         [0122]    Electricity consumption (W) is indicated on an electric/electronic apparatus, with which it is possible to calculate electricity charge in a planned using time of each electric/electronic apparatus. Consequently, it is possible to calculate evaluation of the cost effectiveness of an electric/electronic apparatus, based on electricity charge in a planned using time of each electric/electronic apparatus, and a planned using period. 
         [0123]    For example, in the case where the price of a candidate refrigerator for purchasing is 100,000 yen, the electricity consumption thereof is 100 W, the electricity charge at a certain time in a certain area is 20 yen/kWh (average of daytime electricity charge and nighttime electricity charge), and said refrigerator is used for three years (1095 days), it is possible to provide an evaluation numerical value of (0.1 (kW)×1,095 (days)×24 (hours)×20 (yen/kWh)+100,000 (yen))/1,095 (days)=139.3 (yen/day).
