  The present invention relates to a driving performance reference system that records a driving performance of a driver and can refer to the driving performance.

  In recent years, in the car rental industry, a global positioning system receiver for detecting the position of a vehicle based on radio waves from a satellite, a service for delivering and collecting a rental car using a so-called GPS receiver, and locking a rental car with an IC card Service content such as management has been enhanced (see Patent Document 1). On the other hand, with regard to the rental fee system for rental cars, the rental fee per hour is often set uniformly according to the type of vehicle.

JP 2003-296894 A

  Such rental car rental fees may be accompanied by insurance premiums such as automobile insurance or liability insurance provided in the event of a car accident in addition to the normal rental charges. This insurance premium is often set uniformly regardless of who rents a car. However, the possibility of an accident varies from driver to driver. For example, it is estimated from experience that the former is more likely to have an accident between a driving beginner and a person with a rich driving record. Also, considering the occurrence of an accident in a rental car, it is difficult to cause an accident if the borrowed car model is similar in size to the borrower with a lot of driving experience and driving experience, and on the contrary, the borrowed car model can ride If it is different from the car model, it is presumed that an accident is likely to occur. Therefore, the insurance premium included in the rental fee is determined based on the past driving performance of each borrower, if possible, and the total rental fee should be determined accordingly. However, in order to operate such a rental fee system, it is essential to establish a system capable of recording the driving performance of each driver and referring to the information.

  This invention is made | formed in view of the said subject, and it aims at providing the driving performance reference system which can manage the past driving performance of each driver | operator, and can refer the content.

In order to solve the above problems, the operation performance reference system of the present invention is:
A detachable storage medium having a storage unit for readable and writable storage of driving performance information including a plurality of types of vehicle cases that distinguish vehicle sizes and mileage corresponding to each vehicle type;
A writing device mounted on a vehicle, provided with a holding unit that detachably holds the storage medium, and in which the vehicle case information and mileage information of the vehicle are captured and written to the storage medium;
A holding unit that accepts the recording medium in which a travel distance corresponding to the vehicle case and the distinction of the vehicle case is written, and is detachably held; A reading device for reading out the data of the mileage corresponding to the distinction between the vehicle case and the vehicle case stored in the recording medium;
It is characterized by including.

  According to the present invention, since the vehicle rating of the vehicle that the driver has driven in the past and the travel distance of the vehicle of the vehicle rating can be stored in the recording medium by the writing device mounted on the vehicle, The driver's individual driving performance information can be recorded on the recording medium and managed. In addition, since the recording medium is detachable from the writing device, when driving a different vehicle, the recording medium is taken out and mounted on the writing device of the next vehicle, and the driving performance in the vehicle is recorded. It can be recorded. And since the driving performance information accumulated in the recording medium in this way can be referred to by being read out by the reading device, it receives various services based on the driving performance of the individual driver or based on such driving performance. New services can be provided. These services include, for example, a service that discounts the rental fee of a rental car according to the driving record, a car insurance premium calculation system using the recording medium in which the driving record is recorded, and the like. If the rental fee is discounted, the rental car operator can use this driving performance reference system to understand the driving performance of the borrower of the rental car. If you have a service, you can provide a service that lowers the total rental fee including insurance premiums.

  In the driving performance reference system according to the present invention, the writing device removes the recording medium from the holding unit when it is detected that the vehicle has stopped in a state where the storage medium is held in the holding unit. When the instruction is detected, the mileage of the vehicle is added to the mileage stored in the storage medium so far in correspondence with the same vehicle case as that acquired at that time. The writing process may be performed so as to update the total traveling distance corresponding to the vehicle case.

  Thereby, since the update of the travel distance information which is driving performance information is performed at the time of a vehicle stop, the load of the writing device based on the information update during travel can be reduced. Further, when the recording medium is taken out from the writing device, it can be performed after the travel distance counted so far is recorded.

In addition, the operation performance reference system of the present invention is
A detachable storage medium having a storage unit for readable and writable storage of driving performance information including a plurality of types of vehicle cases that distinguish vehicle sizes and mileage corresponding to each vehicle type;

  The vehicle speed sensor 116 includes a rotation detector such as a known resolver or rotary encoder in order to detect the speed of the vehicle. The detected vehicle speed data is sent to the control circuit 8 (CPU 81).

  The control circuit 108 is configured as a normal computer, and includes a well-known CPU 81, ROM 82, RAM 83, I / O 84 that is an input / output circuit, and a bus line 85 that connects these configurations. The CPU 81 performs control based on programs and data stored in the ROM 82 and RAM 83. The ROM 82 has a program storage area 82a and a data storage area 82b. A navigation program (hereinafter referred to as a navigation program) 82p is stored in the program storage area 82a. Data necessary for the operation of the navigation program 82p is stored in the data storage area 82b. The navigation program 82p operates on the RAM 83 in such a manner that the navigation program work memory 83w is used as a work area.

Become.

  Heretofore, the configuration of the driving performance reference system 100 according to the present embodiment and the update of the driving performance information to the IC card 10 have been described. In the following, a rental car service in which a rental car company can discount a rental fee based on a driving performance of a borrower using this driving performance reference system will be described.

  In the present embodiment, the driving record information is written to the IC card 10 by executing the IC card processing program 82q of the car navigation device 100. Hereinafter, the writing of the operation result information will be described with reference to FIGS. 4 and 5. 4 is a flowchart showing the flow of the IC card processing program 82q for writing the travel distance. FIG. 5 shows the flow of the travel distance addition processing program 82r for adding the travel distance in the IC card processing. It is a flowchart to show.

  First, in S101 of FIG. 4, it is determined whether or not both terminals of the card slot portion of the car navigation apparatus 100 and the IC card 10 are in a connected state. If the connection is established, the process proceeds to S102. If the connection is not established, S101 is repeatedly executed until the connection is confirmed. This determination is made by the CPU 81 based on a connection detection signal from the connection detection sensor 210 provided in the card slot portion.

  Next, in S102, vehicle status information of the vehicle on which the car navigation device (abbreviated as “navi” in the figure) is mounted is read from the external memory 109.

  In S103, it is determined whether or not there is a request to turn off the power of the car navigation device 100. If there is no request to turn off the power, the process proceeds to S104. If there is a request, the process proceeds to S107, the travel distance addition process shown in FIG. 5 is performed, the travel distance up to the time of the request is added to the travel distance stored in the IC card 10, and then this program is terminated. To do. The presence / absence of a power-off request is detected by detecting a signal based on a predetermined power-off operation (for example, turning off the main switch) on the navigation device 100.

  In the travel distance addition process shown in FIG. 5, first, in S201, among the travel distances stored in the IC card 10 corresponding to a plurality of types of vehicle grades, the total travel distance in the vehicle grades read out in S102 is calculated. read out. Next, in S202, the travel distance detected by the distance sensor (corresponding to the travel distance calculation means of the present invention) 104 is added to the travel distance read in S201. In S203, the total travel distance is updated by overwriting the travel distance added in S202 to the travel distance before addition stored in the IC card 10. Note that the distance sensor 104 of the present embodiment is in a state where the detected travel distance is reset when S202 ends, and the travel distance is counted from zero in the next detection. In addition, the travel distance added in S202 may be a travel distance detection means mounted on the vehicle, for example, a detection value of a travel distance meter or the like, instead of the calculated value of the travel distance calculation means included in the car navigation device. good.

  If there is no request for turning off the power of the car navigation device 100 in S103, it is determined in S104 whether there is a request for taking out the IC card 10. If there is a take-out request, the above-mentioned travel distance addition process (FIG. 5) is performed in S106, and the total travel distance of the IC card 10 is updated. In this process, the travel distance detected by the distance sensor 104 up to the time when the take-out request is made is added to the total travel distance, and the travel distance information is updated. After the update, the process returns to S101 again. At this time, the IC card 10 is taken out from the card insertion slot of the car navigation device 100 based on another program. Whether or not there is a request for removing the IC card 10 is determined by detecting a signal based on a predetermined operation for removing the IC card, such as when an IC card removal switch included in the operation switch group 107 is pressed. To do.

  If there is no request for removing the IC card 10 in S104, it is determined in S105 whether or not the vehicle is stopped. If the vehicle is not stopped, the process returns to S103 again. If the vehicle is in a stopped state, a travel distance addition process (FIG. 5) is performed in S106, and a process of updating the total travel distance of the IC card 10 is performed. In this process, the travel distance detected by the distance sensor 104 until the current vehicle stop state is added to the total travel distance, and the travel distance information is updated. Then, after the update, the process returns to S101 again. Note that the vehicle stop state is determined based on the fact that the vehicle speed sensor 116 detects zero, but it is also possible to perform the determination by detecting a parking signal of the vehicle.

  As described above, in this program, the processing is repeated until the power-off request of the car navigation device 100 is issued in S103, and the total travel distance information stored in the IC card 10 is updated.

  Note that the vehicle class information, which is driving performance information, is stored in advance in the external memory 109 of the car navigation apparatus 100, and in S102, the vehicle class information stored in the external memory 109 is read out. The writing of the vehicle qualification information to the external memory 109 is performed by, for example, writing by input from the operation switch group 107 of the car navigation device 100. However, it does not necessarily have to be performed via the operation switch group 107, and may be performed by another method as long as at least a predetermined storage area in which vehicle information is to be stored can be written. For example, a dedicated input device for writing directly to the external memory 109 may be used, and in this case, there is an advantage of preventing writing of vehicle qualification information by a general user.

  Thus, the driving performance reference system of the present invention is configured such that the driving performance of the driver is written on the IC card by the car navigation device mounted on the vehicle. As a result, when a driver drives a different vehicle, the IC card is removed from the car navigation device of the current vehicle and inserted into the car navigation device of the next vehicle. Information can be stored in the IC card 10 in the same manner as the previous vehicle. At this time, even if the vehicle grade is different between the preceding vehicle and the subsequent vehicle, the travel distance is added to the IC card according to the vehicle case.

  In the above, the operation performance reference system of the present invention has been described by taking as an example the case where the system is used as a system for discounting the rental fee of a rental car. In the following, a case will be described in which a rental car company actually uses this system to provide a rental car rental service.

  In the rental car rental service using the driving performance reference system of the present invention, the rental car dealer having the card reader device 20 and the personal computer 30 stores the driving performance information of the person for the rental car borrower. The rental procedure proceeds in the form submitted by the IC card 10. There are various types of rental procedures. For example, the following procedure can be considered.

  First, the rental car company receives the IC card 10 from the borrower, reads the information stored in the IC card 10 (the personal information of the cardholder and the driving performance information) by the IC card reader device 20, and displays the information on the personal computer 30. The information is confirmed on 36. At this time, a table in which personal information of the borrower (upper column in FIG. 6) and driving performance information (lower column in FIG. 6) are collected is displayed on the screen as shown in FIG. At this time, the car rental company confirms the identity from the displayed personal information. When the identity verification is completed, it is determined to which vehicle type the rental car model desired by the borrower belongs. Then, the total mileage of the desired rental car is confirmed from the table on the display 36, the discount amount of the rental fee is determined according to the length of the mileage in the vehicle, and the rental fee is determined. Calculate the total amount.

  In the calculation of the rental fee in this case, the final rental fee is determined by determining the discount amount based on the mileage against the normal rental fee (rental fee when there is no driving record). This substantially means that the result of a predetermined discount on the insurance premium included in the normal rental fee is reflected.

  In this way, by realizing the rental car rental service using the driving performance reference system of the present invention, it becomes possible to rent a rental car at a low price, and the number of rental car users is increased, especially those with abundant driving experience. Can be expected. In addition, in order to realize a discount system based on the above driving results, in general, a rental car company prompts the user (borrower) to register in the vehicle rental system, and the registered user's individual A system is constructed in which information and operation performance information are collected and stored and managed in a central management system having a predetermined server or the like. In this case, since the system becomes extremely large, it is not easy to realize such as an increase in the initial investment amount. However, in the rental car service using the driving performance reference system of the present invention, an IC card owned by the borrower, the IC card reader device 20, and a personal computer (hereinafter also abbreviated as a personal computer) connectable to the IC card reader device 20. Therefore, it can be operated as a relatively small system that is completed at each agency of the rental car dealer.

  In addition, it is not preferable that the owner of the vehicle performs the writing of the vehicle case information in the above embodiment. Assuming that the vehicle owner can arbitrarily input the vehicle case information, the vehicle case information can be written with different information at the vehicle owner's will, causing a problem in the reliability of the written information. . Therefore, it is desirable that the vehicle type information should be entered by a person other than a general user such as the vehicle owner when the car navigation device is mounted, for example, an installer who installs the car navigation device with responsibility so that there is no input error. In addition, it is necessary to take measures to prevent easy rewriting of the car information.

  In addition, the writing of the travel distance in the above embodiment is not limited to the method by the above program, but at least the travel distance detected by the distance sensor is appropriately added to the total travel distance stored in the IC card. I just need it. For example, every predetermined cycle (for example, every 5 seconds), the travel distance detected by the distance sensor may be added to the total travel distance. It is assumed that the detection value of the distance sensor is reset every time the value is added. In this case, since the information update interval is short, even if the distance sensor or the like cannot detect the distance due to some trouble, the travel distance up to that point is added, so the addition loss is small.

  Further, the writing device according to the present invention does not need to be the main body of the car navigation device as in the above embodiment, and can be mounted on at least an unspecified number of vehicles that are expected to be driven by rental car borrowers. As long as the driving performance information can be written in the card 10, the vehicle may be provided as a vehicle-mounted device different from the car navigation device.

  In the driving performance reference system in the above embodiment, the read driving performance information can be referred to, and each value of the read driving performance information is used as a parameter by the rental fee calculation program 33s stored in the HDD 33 of the personal computer 30. It is also possible to calculate rental fees for rental cars.

  When the rental fee calculation program 33s is executed, the rental fee is determined according to the flow shown in FIG. First, the rental car desired by the borrower is input to the personal computer 30 by the input means 37 (S301). Next, the car class of the input car is determined (S302), and the total travel distance of the determined car class is read from the IC card 10 (S303). Based on the travel distance, a discount rate x (%) of the entire rental fee is determined (S305). The discount rate x (%) is determined so that the travel distance is divided in advance for each predetermined range and is determined for each range, and the range where the total travel distance is longer is higher. In this case, the discount rate x (%) is determined by determining which travel distance range the total travel distance belongs to. Finally, the rental fee when the discount rate is 0%, that is, when there is no discount is set as A, and the final rental fee S is calculated by performing an operation of multiplying the fee A by the discount rate x. In the case of the present embodiment, the final rental fee is calculated as S = A × x / 100. Thereby, after reading the information of the IC card 10 into the personal computer 30, the rental fee can be automatically obtained by simply inputting the type or car model of the rental car desired by the borrower.

  As mentioned above, although the Example of this invention was described, these are only illustrations, this invention is not limited to these, A various change is possible unless it deviates from the meaning of a claim. . The present invention is a system that can refer to the driving performance information of the driver. Therefore, the present invention can be applied to various services that utilize the driving performance information. For example, a vehicle insurance company can use the driving performance reference system of the present invention. In this case, the insurance premium can be calculated based on the driving performance stored in the IC card.
