  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The present invention is not limited to the following description, and can be implemented with various modifications.

  FIG. 1 shows a functional block diagram of a system according to the present invention. The system 100 includes a store subsystem 101-1, a management subsystem 101-2, and a user terminal 103. 1 shows one for each of the store subsystem 101-1, the management subsystem 101-2, and the user terminal 103, the store subsystem 101-1, the management subsystem 101-2. Each of the user terminals 103 can be an arbitrary number.

  The store subsystem 101-1 includes a store server 102, a supply device 104, a store terminal 105, and a communication device 106.

  The store server 102 transmits the information collected from the supply device 104, the store terminal 105, and the communication device 106 to the management server 111 constituting the management subsystem 101-2 via the communication network (network) 121. As the main information collected, there is driving information which is information representing the driving situation of the vehicle 10 as described below.

  The communication device 106 communicates with the vehicle-mounted device 11 and receives the vehicle information stored in the vehicle-mounted device 11. Here, the vehicle-mounted device 11 is mounted on the vehicle 10. The vehicle 10 is a vehicle that has arrived at the store where the store subsystem 101-1 is installed. The store is a facility that supplies a vehicle energy source. Specifically, a fuel station such as a gas station, a hydrogen station that supplies hydrogen to a fuel cell, and the like.

  FIG. 2 is a functional block diagram of the vehicle-mounted device 11 attached to the vehicle 10. The in-vehicle device 200 illustrated in FIG. 2 includes a connection unit 201, an ignition ON / OFF detection unit 202, a vehicle information reception unit 203, a vehicle information storage unit 204, and an in-vehicle communication unit 205.

  In the vehicle-mounted device 200, the vehicle information receiving unit 203 receives vehicle information related to driving of the vehicle from each control device (not shown) of the vehicle 10 via the connection unit 201. The control device is a sensor installed in the vehicle. Moreover, there exists an engine electronic control apparatus as a control apparatus. The vehicle information can be received from the control device in real time. Examples of the vehicle information include a travel distance per unit time, a travel time per unit time, and a fuel consumption per unit time. Other vehicle information includes, for example, sudden acceleration, sudden deceleration, sudden steering, speed, continuous operation time, presence / absence of seat belt use, presence / absence of use of mobile phone during driving, outside temperature, wiper operation date / time, ABS (Lock brake system) activation, steering wheel angle, blinker operation date, various information at the time of reverse traveling, fuel remaining amount, and the like. Further, the vehicle information receiving unit 203 can receive information related to ON / OFF of an ignition received from an ignition ON / OFF detecting unit 202 described later. Further, the vehicle information receiving unit 203 may receive information on the ON / OFF of the engine received from the connecting unit 201 without passing through the ignition ON / OFF detecting unit 202.

  The vehicle information received by the vehicle information receiving unit 203 is stored in the vehicle information storage unit 204. The vehicle information storage unit 204 includes a nonvolatile memory such as a flash memory, and the vehicle information is stored in the nonvolatile memory.

  FIG. 3 shows an example of vehicle information. In the example of FIG. 3, information regarding operation management 301, information regarding safe driving support 302, and information regarding inspection and maintenance 303 are shown as vehicle information. Among them, as information regarding the operation management 301, for example, the engine ON / OFF date and time, the travel distance per unit time, and the travel time per unit time are shown. The unit time refers to a predetermined length of time such as 1 minute or 24 hours. For example, the unit time may be an interval at which the vehicle information receiving unit 203 receives vehicle information via the connection unit 201.

  As information related to the safe driving support 302, for example, as information received for each event and in units of one day, the number of stored sudden accelerations, sudden decelerations, sudden steerings, the number of times the mobile phone is used during traveling, ABS, The number of activations, etc., and information received in units of one day include: stored continuous operation time, sudden start rate defined by average speed after n seconds after start, constant speed cruise rate, presence / absence of seat belt, There are outside temperature, blinker differential rate when changing lanes, number of pauses, speed during back travel, number of backs, etc.

  As information regarding the inspection and maintenance 303, for example, there is an entire travel distance measured by the vehicle. The total travel distance is always measured by the vehicle. Further, as other information related to the inspection and maintenance 303, there are information such as engine oil exchange, brake oil exchange, cooling water exchange, tire exchange, wiper rubber exchange, and brake pad exchange that are received and accumulated according to the date and time and travel distance. .

  When the driver of the vehicle arrives at a store (for example, a fueling service station) in which the store subsystem 101-1 is mounted and turns off the ignition, the ignition ON / OFF detection unit 202 of the vehicle-mounted device 11 (200) is connected. Based on the information received from the unit 201, the ignition OFF is detected. Information indicating the detected ignition OFF is transferred to the vehicle information receiving unit 203 and stored in the vehicle information storage unit 204. Information indicating the detected ignition OFF is also transferred to the in-vehicle communication unit 205.

  When the information indicating the ignition OFF is transferred, the in-vehicle communication unit 205 determines whether communication with the communication device 106 of the store subsystem 101-1 is possible. For example, the in-vehicle communication unit 205 determines whether WiFi communication with the communication device 106 can be established. In the present invention, the communication performed by the in-vehicle communication unit 205 with the communication device 106 is not limited to the one using WiFi, and other short-range wireless communication can be used.

  When communication with the communication device 106 is established, the in-vehicle communication unit 205 reads the vehicle information stored in the vehicle information storage unit 204 and transmits the vehicle information to the communication device 106. The vehicle information transmitted to the communicator 106 has been accumulated since the first ignition ON after the ignition OFF when the in-vehicle communication unit 205 established communication with the communicator 106 last time in order to prevent duplication and the like. Vehicle information is preferred.

  Returning to the description of the store subsystem 101-1. When the communication device 106 receives the vehicle information from the vehicle-mounted device 11, the communication device 106 transfers the vehicle information to the store server 102, and the store server 102 stores the vehicle information received by the transfer in the storage device.

  Moreover, the supply apparatus 104 supplies energy sources, such as gasoline, with respect to the vehicle 10 which arrived at the store. Other examples of energy sources include light oil, hydrogen, electricity and the like. When the supply of the energy source is completed, the supply device 104 transfers the amount of the energy source supplied to the vehicle 10 to the store server 102, and the store server 102 stores the amount of the energy source received by this transfer in the storage device. To do.

  The store terminal 105 is a terminal for paying the price of the energy source supplied to the vehicle 10 by the supply device 104. With this settlement, it is possible to specify which supply device 104 is used to supply the energy source to the vehicle 10. Further, when payment is made with a credit card, the payer is specified by the member information included in the credit card information or the credit card number itself. If the vehicle is associated with the payer, the vehicle is identified, and the vehicle information received by the communicator 106 can be identified.

  When a plurality of supply devices 104 are installed in the store where the store subsystem 101-1 is installed, the communication device 106 is obtained by photographing the vehicle number plate and recognizing the vehicle number and the shooting position. It is possible to identify which vehicle information the received vehicle information belongs to.

  FIG. 4 is a flowchart of processing of the vehicle-mounted device according to the present embodiment. In step S401, the ignition ON / OFF detection unit 202 determines whether information indicating ignition ON is received from the connection unit 201. If it is determined that the information indicating the ignition ON has been received, the process proceeds to step S402, the vehicle information receiving unit 203 receives the vehicle information via the connection unit 201, and the process of step S403 is performed. The vehicle information storage unit 204 stores the received vehicle information. In step S404, the ignition ON / OFF detection unit 202 determines whether information indicating ignition OFF is received from the connection unit 201. If information indicating ignition OFF is not received, the process returns to step S402. If information indicating OFF is received, the process proceeds to step S406.

  If it is determined in step S401 that information indicating ignition ON is not received, the process proceeds to step S405, and the ignition ON / OFF detection unit 202 indicates information indicating ignition OFF from the connection unit 201. Determine whether or not is received. If it is determined that information indicating ignition OFF has been received, the process proceeds to step S406, and the in-vehicle communication unit 205 determines whether communication with the communication device 106 is possible. If communication with the communication device 106 is possible, the process proceeds to step S407, and the vehicle information stored in the vehicle information storage unit 204 is transmitted. Further, as the processing in step S408, the vehicle information stored in the vehicle information storage unit 204 may be deleted from the vehicle information storage unit 204. Thereafter, the process returns to step S401.

  If it is determined in step S406 that the in-vehicle communication unit 205 cannot communicate with the communication device 106, and if it is determined in step S405 that information indicating ignition OFF is not received, the process proceeds to step S401. Return processing.

  FIG. 5 is a flowchart for explaining the processing of the store subsystem 101-1. In step S601, it is determined whether a vehicle is detected. For example, it is detected whether the vehicle is photographed by a camera or the like. If a vehicle is detected, the process proceeds to step S602, and it is determined whether communication with the vehicle-mounted device 11 is possible (step S602 may be performed as the process of step S601). If it is determined that communication with the vehicle-mounted device 11 is possible, the process proceeds to step S603, vehicle information is received, vehicle information is transferred from the communication device 106 to the store server 102, and vehicle information is transferred to the store server 102. Remember. In step S604, vehicle information is transmitted from the store server 102 to the management server 111. In the process of step S604, the information to be transmitted is not limited to vehicle information, but may include the amount of energy source supplied, information on the person who made the payment, the vehicle number, and the like.

  FIG. 6 shows an example of a data structure for the store server 102 to store information transmitted from the store server 102 to the management server 111. The date and time when the communicator 106 received the vehicle information, the vehicle identified by the information acquired by the store terminal 105, the vehicle ID identified by the recognized number, the date on which gasoline was supplied, and the vehicle information are associated. Is remembered.

  Returning to FIG. If no vehicle is detected in step S601, if communication is not possible in step S602, or if the process in step S604 is completed, the process returns to step S601.

  Next, the management server 111 of the management subsystem 101-2 will be described. FIG. 7 is a functional block diagram of the management server 111. The management server 500 shown in FIG. 7 includes a receiving unit 501, a vehicle information storage unit 502, an evaluation unit 503, an evaluation information storage unit 504, and an evaluation information transmission unit 505. The management server may be referred to as an evaluation server.

  The receiving unit 501 receives vehicle information from the store server 102 of the store subsystem 101-1 using the communication interface of the computer via the communication network 121. The received vehicle information is stored at a predetermined address in a memory of a computer for configuring the management server 111. As described above, the information received from the store server 102 is not limited to vehicle information, and may include a vehicle ID, a supply date and time, and an energy supply amount.

  The vehicle information storage unit 502 stores information received by the receiving unit 501. For example, vehicle information is read from the predetermined address and stored in a large-capacity storage device such as a hard disk of a computer.

  FIG. 8 shows a data structure for storing information by the vehicle information storage unit 502. As shown in FIG. 8, vehicle ID, which is identification information for identifying a vehicle, supply information (amount of supply of gasoline, etc.), total travel distance, travel distance, other information (vehicle ID, supply information, total travel distance, travel distance) Information is stored in each column of (information other than).

  In FIG. 8, the travel distance column stores the travel distance value in the vehicle information received by the receiving unit 501 for each row corresponding to the vehicle. In addition, when the travel distance per unit time is shown like the travel distance of the vehicle information shown in FIG. 3, and the value of several travel distance is contained in the vehicle information about one vehicle received by the receiving part 501. In this case, the sum of a plurality of travel distances can be set as the value of the travel distance column in the data structure of FIG. The total travel distance stores the value of the total travel distance in the vehicle information about one vehicle received by the receiving unit 501. When a plurality of total travel distance values are included in the vehicle information about one vehicle received by the receiving unit 501, the total travel distance with the latest time accumulated in the vehicle information storage unit 204 Can be the value of the total travel distance column in the data structure of FIG.

  That is, in the data structure of FIG. 8, the total travel distance column stores the distance that the vehicle has actually traveled so far, and the travel distance column previously received vehicle information from the store server 102. From this time, the distance in which the vehicle has traveled before the vehicle information is received from the store server 102 is stored. However, when the vehicle travels while the vehicle-mounted device 11 is not connected to the vehicle, there is a period during which the vehicle-mounted device 11 cannot receive vehicle information from the vehicle 10, so the column of travel distance includes a store server in the previous time. A value smaller than the distance traveled by the vehicle may be stored between the time when the vehicle information is received from 102 and the time when the vehicle information is received from the store server 102 at this time.

  In one embodiment of the present invention, from the history of the distance the vehicle has actually traveled so far, from the last time vehicle information was received from the store server 102 until the time when vehicle information was received from the store server 102 at this time The distance traveled by the vehicle during the period between the last time the vehicle information was received from the store server 102 and the time when the vehicle information was received from the store server 102 this time. Is determined to determine whether the vehicle-mounted device 11 has not been connected to the vehicle.

  The evaluation unit 503 uses the vehicle information stored in the vehicle information storage unit 502 to evaluate the driving status of the vehicle.

  Here, the evaluation unit 503 can include a connection rate calculation unit 507 and an operation evaluation unit 508.

  The connection rate calculation unit 507 calculates the ratio of the distance traveled when the vehicle-mounted device 11 is connected to the vehicle 10 with respect to the distance traveled by the actual travel of the vehicle 10. For this calculation, the evaluation unit 503 uses the data structure shown in FIG. That is, for each vehicle, the vehicle ID, the initial connection distance, the unconnected distance, and the total travel distance are associated with the table structure.

  The initial connection distance is the total travel distance obtained from the vehicle information received when the vehicle-mounted device is first connected to the vehicle specified by the vehicle ID. That is, it is the moving distance of the vehicle when the vehicle-mounted device is connected for the first time after the vehicle moves without being connected to the vehicle-mounted device. Therefore, if the initial connection distance is small, it is determined that the distance traveled by the vehicle without being connected to the vehicle-mounted device is also small.

  The unconnected distance is a distance traveled by the vehicle without being connected to the vehicle-mounted device after the vehicle-mounted device is connected to the vehicle for the first time. That is, after the on-vehicle device is connected, the distance between the on-vehicle device and the vehicle is disconnected for some reason, and the on-vehicle device cannot receive vehicle information from the vehicle. Therefore, if the unconnected distance is also small, it is determined that the distance traveled by the vehicle without being connected to the vehicle-mounted device is also small.

  The total travel distance stores the value of the total travel distance in the vehicle information about one vehicle received by the receiving unit 501.

  Therefore, as shown in FIG. 9A, for a vehicle with a vehicle ID of I1, when the initial connection distance is D11, the unconnected distance is D12, and the total travel distance is D13, the vehicle of I1 The distance traveled without connection is (D11 + D12), and the ratio of the distance traveled by the vehicle I1 without connecting the vehicle-mounted device to the total travel distance D13 is (D11 + D12) / D13. If this value is small, the vehicle information received by the management server 111 is close to the vehicle information when the vehicle actually moves, and it is considered that the reliability of evaluation based on such vehicle information is high. Therefore, in order to calculate (D11 + D12) / D13, the values of D11, D12, and D13 can be read from the storage device, stored in the register, and calculated by the CPU.

  Here, the calculation of the unconnected distance can be performed as follows. That is, as shown in FIG. 8, when the vehicle information received by the receiving unit 501 is stored, for the vehicle having I1 as the vehicle ID, the vehicle information is received from the store server 102 last time by the receiving unit 501. The distance traveled by the vehicle until the vehicle information is received by the receiving unit 501 from the store server 102 at this time is T1. In addition, the total travel distance when vehicle information is received by the receiving unit 501 from the store server 102 at this time is D1. On the other hand, since the total travel distance when the vehicle information is received by the receiving unit 501 from the store server 102 last time is D13, if the vehicle-mounted device continues to be connected to the vehicle, D13-D1 should be T1. It is. Therefore, if a difference between D13-D1 and T1 occurs, the vehicle information is received by the receiving unit 501 from the store server 102 last time until the vehicle information is received by the receiving unit 501 from the store server 102 this time. In the meantime, the vehicle has moved without being connected to the vehicle. That is, the distance traveled by the vehicle without connecting the vehicle-mounted device to the vehicle is (D13-D1) -T1.

  More generalized: Of the vehicle information, the total travel distance is an example of a parameter value that is measured on the vehicle side to which the vehicle-mounted device is connected and monotonously increases with the driving of the vehicle. On the other hand, in the vehicle information, the travel distance is a parameter value received from the vehicle to which the vehicle-mounted device is connected at a time interval from the vehicle-mounted device, and from the previous reception to the current reception by the store subsystem. It is an example of the value for calculating | requiring the increment value of a parameter value. Therefore, in one embodiment of the present invention, the difference between the value obtained from the vehicle information received last time and the value obtained from the vehicle information received this time is about the parameter value that monotonously increases with the driving of the vehicle. To do that. Further, for the increment value of the parameter value, the sum of values obtained from the vehicle information received this time is obtained. Then, for each vehicle, the parameter value is updated to the parameter value until the current reception, and the increment value of the parameter when not connected is updated by adding the obtained sum.

  The initial connection distance is an example of a parameter value obtained from the vehicle when the vehicle-mounted device is connected to the vehicle for the first time. This value can be acquired from information that can be obtained when the vehicle-mounted device first communicates with the store subsystem. In addition, since the value of the parameter obtained from the vehicle when the OBE is connected to the vehicle for the first time is generally unchanged with respect to the OBE, even if the value at that time is stored in the OBE, It is considered that the storage area of the vehicle-mounted device is not compressed. Moreover, the value at that time may be transmitted every time when communicating with the store subsystem.

  Therefore, the connection rate calculation unit 507 updates D12 to a value obtained by adding the value of (D13−D1) −T1 to the current value of D12, and updates the value of D13 to D1. Such an update may be executed every time the receiving unit 501 receives vehicle information and the data structure shown in FIG. 8 is updated, or may be executed as a batch process at night.

  The parameter that increases monotonously with the driving of the vehicle can include fuel or power consumption. This is the parameter value received from the vehicle to which the OBE is connected at a time interval from the OBE in this case, and the increment value of the parameter value from the previous reception to the current reception is per unit time. Fuel or power consumption. For example, the fuel consumption calculated from the remaining amount of fuel can be used as a parameter that increases monotonously with the operation of the vehicle. In a gasoline engine or a diesel engine, the amount of fuel injected into the piston can be used. Therefore, the integrated value during the unit time can be used as the increment value.

  As another example, the total operating time length of the microcomputer that controls the vehicle can be used as a parameter that monotonously increases with the driving of the vehicle. It is possible to use the length of time during which the message is received.

  The driving evaluation unit 508 performs evaluation related to driving of the vehicle based on the vehicle information received by the receiving unit 501. Specifically, as shown in FIG. 9B, the vehicle information received by the receiving unit 501 this time is analyzed, and when (the date and time column in FIG. 9B), what kind of behavior is It is prepared for each vehicle as observed (sequence of vehicle behavior in FIG. 9B) and detection value at that time (vehicle operation data such as acceleration, wheel rotation, engine rotation, etc. in FIG. 9B). Add to the data structure you have. This addition may be executed whenever the receiving unit 501 receives vehicle information and the data structure shown in FIG. 8 is updated, or may be executed as a batch process at night.

  The evaluation information storage unit 504 stores the data structure shown in FIGS. 9A and 9B. For example, it is stored in a storage device capable of large-capacity storage.

  The evaluation information transmission unit 505 transmits the result of driving evaluation and the result of calculating the reliability of the evaluation for each vehicle or for each group of vehicles (for example, a group consisting of vehicles owned by a certain company). To do.

  For example, the evaluation information transmission unit 505 performs driving evaluation based on information stored in the data structure illustrated in FIG. For example, reference is made to information such as recorded sudden acceleration, sudden deceleration, sudden steering, etc., which shows the behavior of the vehicle, and is compared with standard driving information. That is, when the number of sudden acceleration, sudden deceleration, and sudden steering is larger than the value specified by the standard driving information, the load applied to the vehicle body is large, and therefore, evaluation is made that the driving is not good. Such evaluation can be performed for each item of vehicle information such as sudden acceleration, sudden deceleration, sudden steering, etc., and for each item, a comparison is made with the values specified in the standard driving information, depending on the magnitude relationship Evaluation can be made. Further, the standard driving information can be provided according to the type of vehicle (for example, the type according to the engine displacement, the type such as the vehicle type).

  Moreover, the evaluation information transmission part 505 can calculate the reliability of driving | running evaluation based on the information stored in the data structure shown to FIG. 8 (A), for example. That is, for each vehicle, a value of (first connection distance + unconnected distance) / total travel distance is calculated, and reliability is calculated according to this value. That is, the value of (first connection distance + unconnected distance) / total travel distance is directly used as a value representing reliability, or (initial connection distance + unconnected distance) / total travel distance is 1.0 or less. .9 or more can have a reliability of “E”, and 0.9 or less of 0.8 or more can have a reliability of “D” or the like.

  The use of the value of (distance at initial connection + non-connection distance) / total travel distance is merely an example. For example, it is possible to use a value calculated by a function that monotonously increases for the initial connection distance and non-connection distance and monotonously decreases for the entire travel distance. In addition, when the initial connection distance is equal to or less than the distance required for normal vehicle delivery, the reliability may be calculated by regarding the initial connection distance as 0. Whether the distance at the time of the first connection is less than the distance required for normal delivery is determined by, for example, the address of the nearest vehicle dealer of the vehicle owner based on the relationship between the vehicle manufacturer and the address of the vehicle owner. Can be determined by calculating the distance to the address of the owner of the vehicle and comparing it with the distance at the first connection.

  In addition, when using a function that increases monotonously for the initial connection distance and unconnected distance and decreases monotonously for the total travel distance, the ratio of the change in the value of the function due to the change in the initial connection distance is It can be made larger than the rate of change in the value of the function due to the change in distance. Thereby, the influence which the distance at the time of first connection has on reliability becomes large, and it can work to connect an onboard equipment as soon as possible after delivery.

  FIG. 10 is a flowchart for explaining the processing of the management server 111. In step S1001, it waits until vehicle information is received by the receiving unit 501. If vehicle information is received, the process proceeds to step S1002, and the vehicle information storage unit 502 stores the received vehicle information. For example, the vehicle information storage unit 502 stores the data in the data structure shown in FIG.

  In step S1003, it is determined whether the vehicle ID has been registered. Usually, when selling an on-vehicle device, the vehicle ID to which the on-vehicle device is connected is determined, and, for example, an entry corresponding to the vehicle is created in the data structure shown in FIGS. However, even if an entry is not made at the time of sale of the vehicle-mounted device, it can be made when the vehicle ID is not registered, and the labor associated with the sale can be saved. That is, it is determined whether or not the vehicle ID is registered, that is, whether or not there is an entry corresponding to the vehicle in the data structures of FIGS.

  If it is determined in step S1003 that there is an entry corresponding to the vehicle, the unconnected distance column is updated as the process of step S1004, and the total travel distance is updated as the process of step S1005. In addition, if the value of the first connection distance column in the data structure of FIG. 9A is an empty value or the like and is indefinite, the value of the total travel distance can be set as the value of the first connection distance column. .

  As processing of Step S1006, processing for updating evaluation information is performed. For example, the data structure corresponding to the vehicle shown in FIG. 9B is updated. Then, the process returns to step S1001.

  If it is determined in step S1003 that there is no entry corresponding to the vehicle, the process proceeds to step S1007, and an entry corresponding to the vehicle is prepared in the data structure shown in FIGS. In step S1008, the total travel distance value is set in the first connection distance column. Further, the column of unconnected distance is set to 0, the column of total travel distance is set to the value of total travel distance, and the process proceeds to step S1006.

  Returning to the description of the management subsystem 101-2.
