Description

  The present invention relates to a fuel quality determination program, a fuel quality determination method, and a fuel quality determination device, and more particularly to a fuel quality determination program, a fuel quality determination method, and a fuel quality determination device that determine the quality of fuel in equipment.

  In recent years, as fuel costs of vehicles such as automobiles and motorcycles soar, awareness of fuel consumption by drivers (drivers) has increased.

  On the other hand, there is an undeniable possibility that poor quality fuel will be sold at the service station (SS).

  In such a situation, it can be said that it is the driver's natural psychology that makes the fuel quality questionable when the fuel economy of the vehicle he / she drives deteriorates.

Each SS generally has the brand name of the former dealer, and the former dealer has a demand to prevent the sales of bad products in its own brand in order to protect the corporate image.

  However, since the SS and the original dealer are separate companies, it is actually difficult for the original dealer to manage the quality of each SS. Even if it is possible to conduct an on-site survey for SSs, there are many SSs nationwide. In addition, a quality inspection of the SS fuel tank requires an investigation by a specialist. Therefore, there is a problem that such an on-site investigation is very expensive.

  The above-described problems are not limited to vehicles, but can be said to be common to devices that drive using fuel.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a fuel quality determination program, a fuel quality determination method, and a fuel quality determination apparatus that can appropriately determine the quality of fuel.

  Therefore, in order to solve the above-described problem, the fuel quality determination program causes the computer to record the subject information that identifies the device or the operator of the device every time the device is refueled, and the period of time since the last refueling. Refueling information input procedure for accepting input of information specifying the driving amount of the device and the consumption amount of fuel, fuel consumption is calculated based on the driving amount and the consumption amount for each period, and indicates the calculated fuel consumption A fuel efficiency calculation value for recording fuel efficiency information in association with the subject information in a storage device, and a function value of the fuel efficiency for each period with respect to the average value of the fuel efficiency for each set of fuel efficiency information associated with the same subject information And a quality determination procedure for determining the quality of the fuel for each period based on the function value.

  Such a fuel quality determination program can appropriately determine the quality of the fuel.

  ADVANTAGE OF THE INVENTION According to this invention, the fuel quality determination program, the fuel quality determination method, and fuel quality determination apparatus which can determine the quality of a fuel appropriately can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a network configuration example of a fuel management system according to an embodiment of the present invention. In FIG. 1, a host computer 100 includes a POS (Point Of Sales) terminal 2 installed in a gas station such as a service station (SS), a mail server 3 that controls transmission / reception of electronic mail, It is connected to a WWW server 4 that manages Web fuel consumption information related to driver fuel consumption.

  Vehicles 5 such as automobiles and motorcycles used by the driver are refueled at a service station as necessary. Further, the driver connects the Web fuel consumption information managed by the host computer to the WWW server via the Internet 7 using an information terminal 6 such as a PC (Personal Computer) or a mobile phone as necessary. refer. Further, the driver receives notification of information on fuel consumption from the host computer 100 via the mail server 3.

  The host computer 100 is a server computer that collects and manages information related to refueling and fuel consumption, and the entire apparatus is controlled by a CPU (Central Processing Unit). The host computer 100 includes, as software, an output control unit 101, an input control unit 102, a display control unit 103, a communication control unit 104, an installer 105, a customer information management unit 106, a mail server management unit 107, a WWW server management unit 108, and fuel consumption information. A management unit 109, a reliability determination unit 110, a quality determination unit 111, a fuel supply information table 121, a fuel consumption information table 122, a customer information table 123, a reliability determination master 124, a quality determination master 125, and the like. The functions in the host computer 100 may be made available in the form of an ASP (Application Service Provider) that provides collected information to a contracting institution.

  The output control unit 101 controls output data in accordance with an instruction from the CPU and outputs it to a printer or the like. The input control unit 102 controls input data input with a keyboard, a mouse, or the like. The display control unit 103 controls display data to control display on a monitor or the like.

  The communication control unit 104 controls communication with the POS terminal 2, the mail server 3, and the WWW server 4 of the service station, which is performed by the host computer 100 via a network such as the Internet or a LAN (Local Area Network).

  When the storage medium 20 storing a program for realizing processing in the host computer 100 is set in the driver, the installer 105 reads the program from the storage medium 20 and installs it in the auxiliary storage device. Execution of processing in the host computer 100 is realized by the CPU performing it according to a program installed in the auxiliary storage device. The recording medium 20 may be any medium that can be read by a computer. For example, it is a CD-ROM (Compact Disc Read-Only Memory). The program may be downloaded via a network and installed in the auxiliary storage device. Processing in the host computer 100 described below is executed under the control of the CPU.

  The customer information management unit 106 manages customer information related to drivers performing fuel efficiency management using the host computer 100 in the customer information table 123. The mail server management unit 107 notifies information about fuel consumption by e-mail. The WWW server management unit 108 updates the information disclosed on the WWW server based on the information received from the POS terminal 2 of the service station, or the WWW server 4 receives from the driver PC 6 via the Internet 7. Receive update information by information.

  The fuel consumption information management unit 109 manages the fuel supply information received from the POS terminal 2 for each member ID in the fuel supply information table 121. The fuel consumption information management unit 109 calculates fuel consumption information for each travel period (a period between a fueling date and a fueling date) based on the fueling information and the like, and manages the fuel consumption information in the fuel consumption information table 122. The refueling information table 121, the fuel consumption information table 122, the customer information table 123, and the like are recorded in the auxiliary storage device of the host computer 100, for example.

  Based on the reliability determination master 124, the reliability determination unit 110 determines reliable fuel consumption information in determining the fuel quality from the fuel efficiency information managed for each traveling period in the fuel efficiency information table 122. The reliability determination master 124 is information in which a reference (threshold value) that can be trusted in determining the quality of fuel is registered, and is recorded in, for example, an auxiliary storage device of the host computer 100.

  The quality determination unit 111 determines the quality of the fuel for each service station (SS) based on the fuel consumption information extracted by the reliability determination unit 110. The reason for determining the quality of the fuel based on the fuel efficiency information is that there is a very high correlation between the fuel efficiency and the quality of the fuel. However, the cause of the deterioration of fuel consumption is not limited to the quality of fuel. For example, (1) cause of the vehicle (decrease in tire pressure, oil deterioration, driving part failure, etc.), (2) cause by driving (change in driver, change in driving method, etc.), (3) driving environment (4) Causes caused by fuel (deterioration of quality due to poor use, etc. for a while) (4) Causes caused by slopes (winds, winds, snows, road conditions, etc.) Can be considered. Based on the quality determination master 125, the quality determination unit 111 appropriately determines the possibility that the fuel is a poor product from various possibilities. The quality determination master 125 is information in which determination criteria (threshold values) for fuel quality are registered, and is recorded in, for example, an auxiliary storage device of the host computer 100.

  Hereinafter, processing performed by the service station 2 and the host computer when the driver visits the service station 2 will be described.

  FIG. 2 is a flowchart for explaining a processing procedure when the driver visits the service station. In this embodiment, the full tank method will be described as an example. The full tank method is based on the premise that a full tank is always filled when refueling. Therefore, in the case of the full tank method, the fuel supply amount can be regarded as the consumption amount from the previous fuel supply to the present (current fuel supply).

  When the driver (customer) visits the service station 2 as a customer (S11), the serviceman determines whether the customer has already registered a member ID (S12). If it does not have a member ID, member registration is performed (S13). In member registration, customer information is input via the POS terminal 2, for example, and transmitted to the host computer 100. The customer information management unit 106 of the host computer 100 registers the customer information in the customer information table 123. Note that the POS terminal 2 is installed in a fueling machine, for example.

  FIG. 3 is a diagram illustrating a configuration example of a customer information table. In FIG. 3, the customer information table 123 manages information such as member ID, name, address, date of birth, gender, vehicle name, manufacturer, model number, fuel type, tank capacity, e-mail address, and remarks 1 to 3. It is a table and is configured for each member (for each vehicle). The member ID is automatically numbered and registered by the customer information management unit 106 at the time of member registration. As information other than the member ID, a value transferred from the POS terminal 2 is registered as customer information. The name, address, date of birth, gender, and e-mail address are the name, address, date of birth, gender, and e-mail address of the driver that is the object of membership registration. The vehicle name, manufacturer, model number, and tank capacity are the vehicle name (product name) of the driver, the manufacturer of the vehicle, the model number of the vehicle, and the fuel tank capacity of the vehicle. The fuel type is a type of fuel that can be used by the vehicle. Additional information is registered in the remarks.

  In FIG. 2, when the member registration is completed, the process proceeds to step S15.

  On the other hand, if the driver has registered as a member and has a member ID, the member ID is input to the POS terminal 2 by the service person. As a result, the POS terminal 2 acquires the member ID of the driver (S14).

  The service person refuels the driver's vehicle and sells the fuel, and inputs refueling information such as the refueling amount, the type of fuel refueled, and the price to the POS terminal 2 (S15). In this embodiment, since the full tank method is assumed, the fuel is supplied until the tank is full.

  Subsequently, the total travel distance of the vehicle is input to the POS terminal 2 by the service person (S16). The POS terminal 2 determines whether or not the input total travel distance is an appropriate value by comparing the input total travel distance with the previously registered total travel distance (S17). When it is not appropriate, the difference between the total travel distance input this time and the previous total travel distance (difference travel distance) is less than 0, or the fuel consumption calculated based on the difference travel distance is outside the preset range. This is the case in some cases. The previous total travel distance is registered in the refueling information table 121. Therefore, after the member ID is input, the POS terminal 2 can transmit the member ID to the host computer 100 and obtain the value corresponding to the member ID from the refueling information table 121 for the previous total travel distance. That's fine.

  If the total travel distance is reasonable, the process proceeds to step S18. If it is not appropriate, for example, as a precaution, the driver is asked to confirm and the total travel distance is acquired again and input to the POS terminal 2 (S16). In this case, the POS terminal 2 may be configured to have the determination process of step S17, or the host computer 100 may be inquired.

  Subsequently, the POS terminal 2 collects the member ID, the refueling information, the total travel distance, the unit price of the refueled fuel, and the ID for identifying the service station 2 (SS) (hereinafter referred to as “SSID”). ) Is transmitted to the host computer 100 (S18). The SSID may be stored in the POS terminal 2 in advance, or may be input to the POS terminal 2 by a service person. When the host computer 100 receives the refueling information from the POS terminal 2, the fuel efficiency information management unit 109 registers the refueling information regarding the member ID in the refueling information table 121.

  FIG. 4 is a diagram illustrating a configuration example of a fuel supply information table. In FIG. 4, a refueling information table 121 is a table for managing information such as date, total travel distance, refueling amount, tank capacity, fuel type, unit price, and SSID for each refueling (each time refueling information is received). Yes, created for each member (each vehicle). The date is the date on which refueling was performed. The values transmitted from the POS terminal 2 are registered in the total travel distance, the amount of fueling, the fuel type, the unit price, and the SSID. As the tank capacity, a value registered in the customer information table 123 corresponding to the member ID is posted.

  Assuming that the date of refueling in this embodiment (the refueling date) is February 7, in step S18, the date is “2007/2/7”, that is, the total travel distance is “6036”. In addition, a record with the oil supply amount “41.1”, the tank capacity “45”, the unit price “120”, and the SSID “EN0077” is registered in the oil supply information table 121.

  Subsequently, the fuel consumption information management unit 19 calculates each numerical value (fuel consumption information) based on the received fuel supply information and the like, and registers the fuel consumption information in the fuel consumption information table 122 (S19).

  FIG. 5 is a diagram illustrating a configuration example of the fuel consumption information table. In FIG. 5, the fuel consumption information table 122 includes a travel distance, a fuel supply amount, a fuel consumption, a unit price, a cost efficiency, a tank capacity, a fuel supply rate, and a standard deviation for each travel period (a period from the previous refueling to the current refueling). Is a table for managing information such as deviation value, average ratio, elapsed days, and SSID, and is created for each member (for each vehicle). For example, when refueling is performed on February 7, 2007, the last record in FIG. 5 is registered. The travel distance is a travel distance during the travel period. The oil supply amount is the oil supply amount on the current oil supply date (“2007/2/7” for the last record). The fuel consumption is the fuel consumption during the travel period. The unit price is the unit price of fuel on this refueling date. The cost efficiency is a cost (amount) per 100 km during the traveling period. That is, the cost efficiency is an index that indicates economic efficiency including both the price of fuel and the fuel efficiency. The tank capacity is the capacity of the fuel tank of the member's vehicle. The meaning of the fueling rate, standard deviation, deviation value, average ratio, and elapsed days will be described when calculating the index. The SSID is an SSID of an SS (service station) that has been refueled on the refueling date that is the starting point of the travel period. Details of step S19 will be described later.

  Subsequently, the customer information management unit 106 of the host computer 100 searches the customer information table 123 for the customer information of the driver based on the member ID, and confirms whether or not the e-mail address is registered (S20). When the e-mail address is registered, the mail server management unit 107 creates an e-mail in which fuel consumption information by the current refueling is described, and provides the e-mail to the driver via the mail server 3 (S21). . Subsequently, the WWW server management unit 108 updates the fuel consumption information corresponding to the member ID managed by the WWW server 4 (S22), and ends the process of FIG.

  On the other hand, if the e-mail address is not registered, the WWW server management unit 108 updates the fuel consumption information corresponding to the member ID managed by the WWW server 4 without providing the fuel consumption information by e-mail (S22). ), The process of FIG.

  Next, fuel consumption information calculation and registration processing executed by the fuel consumption information management unit 109 in step S19 of FIG. 2 will be described. FIG. 6 is a flowchart for explaining calculation and registration processing of fuel consumption information by the fuel consumption information management unit.

In step S101, the member ID received together with the refueling information from the POS terminal 2 is acquired. (S101). Subsequently, the previous total travel distance (d ₀ ) and the previous refueling date (Date ₀ ) are acquired from the previous registration information (second record from the end) in the refueling information table 121 (S102). Subsequently, the current total travel distance (d ₁ ), the current refueling amount (L ₁ ), the current unit price (P ₁ ), and the current registration information (last record registered this time) in the refueling information table 121, Obtain the current refueling date (Date ₁ ).

Subsequently, by calculating the current total travel distance (d ₁ ) −the previous total travel distance (d ₀ ), the travel distance from the previous refueling time to the current refueling time (current travel time) (D ₁ ) is calculated (S104). Subsequently, the fuel consumption (N ₁ ) of the current travel period is calculated by calculating the travel distance (D ₁ ) / current oil supply amount (L ₁ ) of the current travel period (S 105). In the full tank method, the amount of fuel can be regarded as the amount of consumption, so the fuel consumption is calculated using the current amount of fuel. Subsequently, the current cost (C ₁ ) is calculated by calculating the current unit price (P ₁ ) × the current oil supply amount (L ₁ ) (S 106). Subsequently, the current cost efficiency (E ₁ ) is calculated by calculating the current cost (C ₁ ) / current travel distance (D ₁ ) × 100 (S 107).

  Subsequently, it is determined whether or not the number of refueling is 30 or more (whether or not the number of records in the refueling information table 121 is 30 or more) (S108). Here, the number of times of refueling is determined because an index calculated in the following is low in the reliability of the value unless there is a certain number of samples (number of times of refueling), and a criterion for judging the quality of fuel in the processing described later It is because it thinks that it is not appropriate to use for. Therefore, when the number of refueling is less than 30 (No in S108), the calculation results so far are registered in the fuel consumption information table 122 without executing steps S109 to S114 (S115).

When the number of times of refueling is 30 times or more (Yes in S108), the tank capacity (TL) is determined from the refueling information table 121 or the fuel consumption information table 122, the previous refueling amount (L ₀ ) is determined from the refueling information table 121, and the fuel consumption information table 122 is displayed. A past fuel consumption (N _n ) is acquired (S109). Here, the past fuel consumption (N _n ) refers to the fuel consumption in a predetermined number of records in all or newest order registered in the fuel consumption information table 122. Therefore, the past fuel consumption (N _n ) is composed of a plurality of fuel consumption values.

Subsequently, by calculating the previous refueling amount (L ₀ ) / tank capacity (TL), the proportion of the fuel refueled in the fuel tank at the last refueling (current travel period) (ie, An oil supply rate (PP ₁ ) which is the concentration of fuel supplied last time) is calculated (S110). Subsequently, a standard deviation (HH ₁ ) of a set (existing fuel consumption N) of past fuel consumption (N _n ) and current fuel consumption (N ₁ ) is calculated (S111). Subsequently, the deviation value (NH ₁ ) of the current fuel consumption (N ₁ ) in the existing fuel consumption N is calculated (S 112). Subsequently, an average ratio (HW ₁ ) that is a ratio of the current fuel efficiency (N ₁ ) to the existing average value of the fuel efficiency N is calculated (S113). Subsequently, the number of elapsed days (KD ₁ ) (that is, the number of days in the current travel period) is calculated by calculating the current refueling date (Date ₁ ) −the previous refueling date (Date ₀ ) (S 114). Subsequently, the calculation results and the like so far are registered in the fuel consumption information table 122 (S115). The previous refueling date (Date ₀ ) is registered as the start date (self) of the travel period, and the current refueling date (Date ₁ ) is registered as the end date (solstice) of the travel period. In addition, the SSID on the previous refueling date is transferred from the refueling information table 121 to the SSID. This is because the fuel used in the current traveling period was refueled on the previous refueling day.

  Subsequently, processing executed by the reliability determination unit 110 will be described. The reliability determination unit 110 is asynchronous with the above-described process (for example, once a day), and the reliability of each record registered in each fuel consumption information table 122 of all members (based on the fuel quality determination criteria). (Relevance to use) is determined, and a process for selecting (extracting) a reliable record is executed. The reliability determination unit 110 determines the reliability of the current record by comparing the current record with the conditions registered in the reliability determination master 124.

  FIG. 7 is a diagram illustrating a configuration example of the reliability determination master. As shown in the figure, in the reliability determination master 124, a determination oil supply rate, a determination standard deviation, and a determination freshness are set as reliability determination criteria (threshold values). In the example of the figure, the determination oil supply rate is 85%, the determination standard deviation is 1 km / l, and the determination freshness is 15 days. Freshness refers to the freshness of fuel, and is a reference value for the number of days elapsed in the record of the fuel consumption information table 122. The reason why the fueling rate is used as a criterion is that it is not appropriate to use the fuel efficiency calculated in a state where the mixing rate of fuel supplied in other SSs is high for the determination of fuel quality of a specific SS. . The reason why the standard deviation is used as a criterion is that it is not appropriate to judge the quality of the fuel based on data having a large variation in fuel consumption. The criterion for freshness is that the quality of fuel tends to deteriorate over time, so it is not appropriate to use data over a long period of travel as a criterion for quality of fuel sales. Because. Note that the value of the reliability determination master 124 is preferably editable. By doing so, the value may be changed according to the operation. Further, the parameters used as the determination criteria may be changed as appropriate.

  FIG. 8 is a flowchart for explaining reliability determination processing by the reliability determination unit.

  In step S201, a record in which the fueling rate is higher than the determined fueling rate is extracted (searched) from all the records registered in each fuel consumption information table 122 of all members. Subsequently, a record having a standard deviation lower than the determination standard deviation is extracted from the extracted records (S202). Subsequently, a record in which the number of elapsed days (the number of days in the travel period) is smaller than the number of days indicated in the determination freshness is extracted from the extracted records (S203). Subsequently, the extracted records are classified by SSID (by service station (SS)), and fuel efficiency data by SS is created for each classified record (S203). The created data is recorded in the storage device of the host computer 100.

  FIG. 9 is a diagram showing a configuration example of SS fuel efficiency data. In the figure, each record of the fuel efficiency information data 151 by SS has items such as a refueling date, an update date, a deviation value, an average ratio, and an SSID. The values of these items are transcribed from the records extracted from the fuel consumption information table 122. However, for the sake of convenience, the contents of FIG. 9 do not correspond to FIG. The refueling date corresponds to the start date of the travel period. The update date corresponds to the end date of the travel period.

  As described above, the fuel efficiency information data by SS is created for each SS. The SS fuel consumption data 151 shown in FIG. 9 is SS fuel consumption data for an SS with an SSID of “EN0075”.

  Subsequently, based on the SS fuel consumption data 151 and the quality determination master 125 created for each SS by the reliability determination unit 110, the quality determination unit 111 determines the quality of the fuel sold at each SS. .

  FIG. 10 is a diagram illustrating a configuration example of the quality determination master. As shown in the figure, in the quality judgment master 125, the judgment average ratio, the number of data cases, and the abnormal data ratio are set as quality judgment criteria (threshold values). The meaning of each value is clarified in the processing procedure described later. The value of the quality judgment master 125 is preferably editable. By doing so, the value may be changed according to the operation. Further, the parameters used as the determination criteria may be changed as appropriate.

  FIG. 11 is a flowchart for explaining fuel quality determination processing by the quality determination unit. The process in FIG. 11 is performed batchwise for each SS fuel efficiency information data 151 (for each SS). For example, it may be performed periodically such as once a day or once a week.

  First, in the fuel efficiency information data by SS 151 to be processed, the presence / absence of a refueling date having abnormality data is determined for each refueling date within the past month starting from the time when the processing is performed (S301). Here, the abnormal data refers to records whose average ratio value is less than the quality determination master 125 determination average ratio. For example, in the fuel efficiency information data 151 by SS shown in FIG. 9, there are three records of 2007/1/26 (in FIG. 9, for convenience, a horizontal line is drawn for each refueling day). In this case, if there is at least one record (that is, abnormal data) whose average ratio value is less than the determination average ratio among the three records, the refueling date is determined as “abnormal data present” in step S301.

  The average ratio is the ratio of the fuel consumption related to each refueling day to the average of all the existing fuel consumptions (the normal fuel consumption of the member). Therefore, the smaller the value is, the worse the fuel consumption during the running period after the refueling date is compared to the normal time. Therefore, when the average ratio value is smaller than the value set as the determination average ratio, the quality determination unit 111 determines that there is a probability that the quality of the fuel is bad.

  If there is a refueling date corresponding to the determination in step S301 (Yes in S301), it is determined whether or not there is a refueling date in which the ratio of abnormal data is equal to or higher than the abnormal data ratio in the quality determination master 125 (S302). . For example, in the fuel efficiency information data 151 by SS shown in FIG. 9, there are four records whose refueling date is 2007/2/2, all of which are abnormal data. In this case, it is determined that the abnormal data ratio of the fueling date is 100 (%).

  The reason for making the determination based on the abnormal data ratio is that it is appropriate to doubt the quality of the fuel at the SS when the fuel efficiency is worse than usual at a large number of members. In other words, if the fuel efficiency of only a small number of members is worse than normal, it is considered appropriate to judge that the fuel economy has deteriorated due to the individual circumstances of the member.

  When there is a refueling date corresponding to the determination in step S302 (Yes in S302), it is determined whether or not the number of records of the refueling date is equal to or greater than the number of data in the quality determination master 125 (S303). For example, the number of records of 2007/2/2 is four, which is equal to or greater than the number of data items in the quality determination master 125 in FIG. 10, and therefore the refueling date corresponds to the determination in step S303. Note that the reason why the number of records of the corresponding refueling date is used as a criterion is that the reliability of information is considered to vary depending on the number of samples.

  If there is a refueling date corresponding to the determination in step S303 (Yes in S303), information for notifying that there is a high possibility that the quality of the fuel of the SS is bad is given by a predetermined user (for example, the original It transmits to the person in charge of the quality of each SS, such as the person in charge of a seller (S304). The information to be notified may be, for example, a table as shown in FIG.

  FIG. 12 is a diagram illustrating an example of a normal / abnormal data count table. In the normal / abnormal data number table shown in the figure, for each SSID (SS), the number of normal data (records) and the number of abnormal data (records) are shown for each refueling date in the past month. . The predetermined user can know the tendency of the quality of the fuel in the SS by referring to such a table.

  Moreover, it is good also considering the graph as shown in FIG. 13 as notification information. FIG. 13 is a graph showing the average ratio of the past month in time series. In the graph of the figure, the horizontal axis represents the fueling date and the vertical axis represents the average ratio. The predetermined user can easily grasp the tendency of the fuel quality in the SS by referring to such a graph.

  On the other hand, when there is no refueling date corresponding to the determination in step S303 (No in S303), warning information (for example, SS name) indicating that the quality of the SS may be poor is electronically transmitted to a predetermined user or call center. It is transmitted by e-mail or the like (S305).

  Further, when there is no refueling date corresponding to the determination in step S302 (No in S302), in step S306, for the refueling date corresponding to the determination in step S301 (the refueling date with abnormality data), the same as in step S303. Make a decision. If there is a refueling date corresponding to the determination in step S306 (Yes in S306), reference information notifying that abnormal data existed in the past is transmitted to the call center by e-mail or the like (S307). When there is no refueling date corresponding to the determination in step S306 (No in S306), there is a high possibility that the abnormal data is a member's individual circumstances, and no notification is given (S308).

  On the other hand, when there is no refueling date corresponding to the determination in step S301 (No in S301), it is determined whether the number of records of any refueling date is equal to or greater than the number of data in the quality determination master 125 (S309). When the determination is affirmative (Yes in S309), the SS transmits information notifying that the SS is highly safe with respect to quality, for example, to a call center by e-mail or the like (S310). If the determination is negative (No in S309), the process is terminated without any particular notification (S311).

  In addition, although the example which determines the quality of quality using an average ratio was shown above, you may use a deviation value instead of an average ratio or with an average ratio. In this case, a determination deviation value (deviation value threshold value) may be set in the quality determination master 125 instead of the determination average ratio or together with the determination average ratio. When the deviation value of the fuel consumption is lower than the determination deviation value, it may be determined that the fuel consumption is worse than usual. Similarly, an absolute value of fuel consumption may be used.

  However, since the absolute value of the fuel efficiency differs depending on the driver and the vehicle type, it is preferable to determine the quality based on the deviation value or the average ratio when the quality determination master 125 determines the quality uniformly. For drivers with small variations in standard deviation, a slight difference in fuel consumption may greatly affect the deviation value. In view of such points, the average ratio is preferable to the deviation value.

  As described above, according to the host computer 100 in the present embodiment, the quality of the fuel is determined based on the function value with respect to the average value of the fuel consumption such as the average ratio and deviation value calculated for each member and for each travel period. The Therefore, it is possible to determine the quality of the fuel for each traveling period (each refueling day) by absorbing differences in various circumstances and vehicle types for each member.

  Further, since the fuel consumption information and the like are managed in association with the SSID, it is possible to specify an SS that is estimated to have poor quality.

  In addition, by enabling judgment of fuel quality, the original dealer can respond to complaints from users logically about the cause of fuel consumption deterioration and can also answer about guarantee of gasoline quality. . Therefore, the brand image can be maintained.

  In addition, it is possible to give the service station a psychological deterrent against the handling of inferior goods, in which the fuel quality is monitored.

  Further, even when an on-site inspection or the like is required for the service station, it is possible to narrow down the service stations with questionable quality, and thus the cost for the inspection can be reduced.

  In addition, the service station can gain the trust of the user by appealing that it is participating in the system.

Furthermore, the user can purchase the service station adopting this system with confidence in the quality of the fuel. In this embodiment, for the sake of convenience, the fuel supply amount is regarded as the fuel consumption amount. An example in which the full tank method was adopted was explained. However, it is not necessary to use the full tank method for a vehicle in which the remaining amount of fuel in the fuel tank can be measured by a sensor or the like. In this case, the difference between the remaining amount after the previous refueling and the remaining amount before the current refueling may be used as the fuel consumption.

  Further, the application target of the fuel quality determination method and the like in the present embodiment is not limited to the vehicle. Any device that is driven by fuel may be used.

  As mentioned above, although the Example of this invention was explained in full detail, this invention is not limited to such specific embodiment, In the range of the summary of this invention described in the claim, various deformation | transformation・ Change is possible.
